WORKING SCENARIO

Using this module, the idea is that students should become experts in biotechnology and that, after performing a series of activities, they should be able to develop a communication campaign as a final product to explain what biotechnologies are, focusing on the field of biomedicine.

With this aim, they cover different aspects of biotechnology: what it consists of, applications, advantages and disadvantages, etc. Although the focus of the work is mainly scientific, the legal and social aspects that often block the advance of particular lines of research in this field are not ignored.

The suggested activities in this module deal with current research issues and are dynamic, practical and experimental. In this way, the idea is that students should learn in a competence-based, meaningful way, controlling their own learning process and building a solid structure allowing them to apply the knowledge learned in many areas of their life, becoming citizens with opinions based on scientific evidence and critical reasoning.

COMPETENCES ACQUIRED

Level Key stage 4 (year 11)

Contributions to key cross-disciplinary competences

Linguistic sphere

Linguistic and communication competences are constantly covered throughout the module, as in each of the activities the students need to interpret and/or express concepts, thoughts, facts and opinions, both orally and in writing.

Page 7: The biotechnology revolution - Xplore Health · Characterisation of the cell division process by mitosis. 20. Characterisation of the cell division process by meiosis. 21. Cell differentiation

TEACHING GUIDE / THE BIOTECHNOLOGY REVOLUTION / 7

Personal and social sphere

So that students acquire a sufficient level of awareness of their own intellectual, emotional and physical capacities, throughout the module there are activities allowing them to direct their own learning (Review of the definition of biotechnology, Table 13) and control it (creating the conceptual map, Table 8). In this way, they are helped to acquire the skills, strategies and procedures necessary to continue learning increasingly effectively and autonomously.

During the module, many activities are carried out in small groups (What is biotechnology, Table 2; DNA, the essence of biotechnology, Table 3, etc.). This allows interaction between the students and the consequent acquisition of values such as respect, comradeship and cooperation.

Most activities, with their corresponding discussions, allow students to learn from their own mistakes and those of others, as well as developing personal attitudes and values, such as responsibility, perseverance and self-knowledge.

Digital sphere

A great deal of use of digital technologies is made throughout this module: almost all the activities begin by showing a video (DNA, the essence of biotechnology, Table 3 and How can DNA be manipulated?, Table 5) or with a computer game (Help me cure Nàdia’s cancer!, Table 10). Other activities also use virtual laboratories to bring research into the classroom (Use organisms to develop a pharmaceutical!, Table 7). The idea of this is that students should develop the capacity to search for and select information which can then be turned into knowledge.

In addition, they work on the capacity to use computers and the applications included in them autonomously, effectively and efficiently.

Specifically, the competences worked on are as follows:

Competence 2. To use text editing applications and multimedia applications to produce documents.

Students are often asked to use digital technologies to create documents, either to share information with classmates or to summarise particular content.

Competence 4. To search for, check and select appropriate digital information for the job to be done, considering various digital sources and media.

Throughout the module, students have to extract information based on various digital sources such as: animations, simulations, video reports, computer games and virtual laboratories.

Competence 7. To participate in virtual interpersonal communication and publication environments to share information.

Students are invited to share what they produce virtually using the Xplore Health blog or other digital platforms chosen by the teacher. In addition, the final aim of the module – to carry out a campaign on biotechnologies – leads to the students undertaking a communication action aimed at society (whatever the means of communication they chose to do it: exhibition at the school, reader’s letter in a newspaper, blog, etc.)

Contributions to scientific and technological competences

The competences in this sphere are intended, on one hand, to use knowledge and a particular methodology to explain nature and, on the other hand, to apply this knowledge and methodology in response to human needs.

Specifically, the competences worked on in this module are as follows:

Competence 2. To identify and characterise biological systems from the point of view of the models for communicating and predicting the behaviour of natural phenomena.

Page 8: The biotechnology revolution - Xplore Health · Characterisation of the cell division process by mitosis. 20. Characterisation of the cell division process by meiosis. 21. Cell differentiation

TEACHING GUIDE / THE BIOTECHNOLOGY REVOLUTION / 8

The use of models is necessary and fundamental for understanding what DNA is and how it works (Table 3 and Table 4), how DNA can be manipulated (Table 5), what the lipid bilayer of a cell is like and what happens when it is mixed with soap (Laboratory practical, Table 6), how the cell cycle goes and the stages that make up the processes of cell division by mitosis and by meiosis (Help me cure Nàdia’s cancer!, Table 10), etc. It is also possible to refer to the model living creature, one of the key biological models, to remember that cells are the fundamental units of life.

Competence 4. To identify and solve scientific problems suitable for investigation in a school context, involving the design, carrying out and communication of experimental research.

This competence is worked on in the laboratory practical (Table 6), in which the students carry out an experimental process allowing them to extract their own DNA.

With a low level of investigation, the practical can be carried out with students only having to follow the protocol to observe a certain phenomenon. If you wish to increase the level of investigation in the practical (and make the work on this competence more meaningful), the students can be made to ask a research question (such as: “How can DNA be extracted from mouth cells?”) and design the most suitable protocol to do this.

This competence is also covered in the virtual laboratory, in the activity Use organisms to develop a pharmaceutical! (Table 7).

Competence 5. Use scientific reasoning to solve everyday problems.

The computer game Help me cure Nàdia’s cancer! (Table 10) means students have to apply different treatments against cancer to help cure Nàdia’s leukaemia. Although this does not take place in an environment very close to students’ lives, they adopt a role in which they have to solve a real life problem by applying scientific reasoning.

Competence 6. Recognise and apply the processes involved in creating and confirming scientific knowledge.

The laboratory practical (Table 6) allows space for the teacher to deal with aspects concerning the nature of science: multidisciplinary teams, work in groups, presence of women in the world of research, etc. It can also be acknowledged that established scientific knowledge, beliefs, expectations, values, conditions and the circumstances of the sociocultural context in which they are developed have an effect when it comes to planning experiments and compiling and interpreting data.

In the case of the activity Help me cure Nàdia’s cancer! (Table 10), it is noted that there is not yet a 100% effective treatment to cure cancer, so reference can be made to the limits currently shown by science or the evolutionary nature of science.

Also during the debate (Table 14) on controversial aspects surrounding biotechnology (gene therapy, cloning, stem cells, etc.) the interpretations and statements related to science published in the media can be evaluated.

Level Key stage 5

Contributions to general Key stage 5 competences

The competences covered in this module are as follows:

Communication competence:

This competence is covered in a cross-disciplinary way throughout the module because in all the activities students have to master both comprehension and expression in oral and written language.

Competence in managing and dealing with information:

The capacity to obtain information from videos is covered in the activities: What is biotechnology? (Table 2), DNA, the essence of biotechnology (Table 3), The biological functions of DNA (Table 4), How is DNA manipulated?(Table 5) and We can cure with cells (Table 11).

Page 9: The biotechnology revolution - Xplore Health · Characterisation of the cell division process by mitosis. 20. Characterisation of the cell division process by meiosis. 21. Cell differentiation

TEACHING GUIDE / THE BIOTECHNOLOGY REVOLUTION / 9

With activities like Use organisms to develop a pharmaceutical! (Table 7), Become a doctor! (Table 9), Help me cure Nadia’s cancer! (Table 10) or Produce skin (Table 12), the information is obtained from computer games.

In either case, students need to turn this information into useful knowledge.

Digital competence:

This competence is covered in a cross-disciplinary way, as each activity in the module uses technological tools, either to process information or provide interaction with virtual networks (like the Xplore Health blog).

As well as providing students with information in the form of videos or computer games in most cases, they are also asked to produce work in which technological tools have to be used. This is the case with the production of a poster (Table 11) or the conceptual map (Table 8) or the dossier with the laboratory practical (Table 6).

Personal and interpersonal competence:

This competence is covered throughout the module, as activities are carried out in pairs or groups of 4 based on cooperative work. This contributes to the development of skills such as self-control, creativity, enterprise and flexibility, allowing each student to achieve self-knowledge and knowledge of others.

Competence in knowledge and interaction with the world:

All activities in the module are intended to provide the students with real situations so that they mobilise their knowledge to carry out actions to solve problems, some of which may be real ones. In this way, throughout the module, students are encouraged to learn from the world (observing it, understanding it and asking themselves questions) and for the world (providing answers to real problems and carrying out actions to improve it). Some of the activities allowing knowledge transfer between the school world and the physical world are: Become a doctor! (Table 9) and Help me cure Nàdia’s cancer! (Table 10).

Contributions to specific subject competences (Biology)

The competences covered in this module are as follows:

Competence in investigation and experimentation:

In the activities Use organisms to develop a pharmaceutical! (Table 7) and Produce skin (Table 12), students find out about laboratory working methods, as well as some of the equipment needed for carrying out research.

Also, the laboratory practical (Table 6) promotes students’ capacity to follow a protocol and acquire habits in the laboratory.

Competence in comprehension and capacity to affect the physical world:

Of all the competences covered, this is the one that best fits with the overall nature of the module, as the ultimate aim of all the activities is for students to be capable of transferring school knowledge into the physical world so they can ask themselves questions, solve real problems and undertake actions with a critical mind, values and ethical criteria.

For example, in the activities Become a doctor! (Table 9) and Help me cure Nàdia’s cancer! (Table 10), students have to make a series of informed decisions to solve a series of problems from the physical world. The debate activity Is biotechnology good for us? (Table 14) promotes students’ critical capacity as, once they have made the fundamental concepts and principles of science their own, they have to position themselves when faced with a series of controversial ethical and social aspects. This subsequently determines their effect on the physical world.

TEACHING ACTIVITIES

We will now explain the different teaching activities proposed in the general sequence: they are placed at the relevant level, an accurate description is made of each one, the content covered is listed, different classroom dynamics are proposed (which you will find described in Appendix 1), as well as control and evaluation activities (see evaluation tools in the section of the same name). Finally, a timing is suggested for each activity. In this sequence, the activities correspond to the numbering in the students’ guide.

For each activity proposed in the module (or small groups of closely related activities), an explanation has been developed, which you will find in the following tables:

TIMING

Reading (1) – Task.

To begin the module, the students read the task suggested to them; they need to become experts in biotechnology to organise a communication campaign offering a more objective image of biotechnologies.

1.Concept of biotechnology.

24.Ethical and social implications of biotechnology.

*In this introductory text the content is not covered in depth, only certain aspects are mentioned.

The reading is done in groups of 4. Each group member reads a paragraph. The member to the right of the one who has read summarises what has just been read and the other two confirm that it has been understood properly.

Finally, the teacher makes an overall explanation summarising the task and placing its importance in context. The teaching intention of this activity must be borne in mind: to motivate students to acquire all the knowledge in the module, as only in this way can they carry out the task.

In Appendix 1 you will find a description of the teaching methods mentioned in this table.

DESCRIPTION CONTENT COVERED PROPOSAL FOR

CLASSROOM TEACHING CONTROL AND EVALUATION TIMING

Activity 1.In this introductory activity, the students are asked what they think biotechnology is.

Activity 2 and 3.They are then shown a video allowing them to improve their expertise on the topic.

Activity 4.They create a description defining what biotechnology is and the applications it has.

Reading (2).They read a text from the student’s material classifying the types of biotechnology depending on their applications.

1. Concept of biotechnology.

2. Fields of application of biotechnology.

Groups of 4 members are set up and all the activities are resolved following the 1-2-4 technique. In addition, at the end of each activity there is a discussion with the whole group/class.

The final reading is done in the same groups of 4. Each group member reads a point. The member to the right of the one who has read summarises what has just been read and the other two confirm that it has been understood properly.

In Appendix 1 you will find a description of the teaching methods mentioned in this table.

Control: this activity at the beginning of the module tries to get the students to externalise their previous ideas and become aware of what they know and what they do not.With this aim, they have to fill in the table in exercise 2 in which they have to write the topic they consider most important and the aspects they do not yet understand.

In addition, in the group work they compare their initial knowledge with that of the classmates, which also promotes control and comparison of this knowledge.

CONTROL AND EVALUATION TIMING

Activity 5. In this activity, the students describe what the DNA molecule is, based on seeing a video.

Activity 6. They then make a three-dimensional representation of the DNA molecule.

Activity 7. Finally, they are led to ask how genetic information is stored in DNA.

3. DNA structure.

4. DNA composition.

5. Information storage in DNA.

Groups of 4 members are set up (these can be the same ones as in the previous session).

After the whole group/class has seen the video, the students describe what the DNA molecule is like, in groups of 4. The answer is then talked about with the whole group/class, using the Number technique.

The three-dimensional representation of the DNA molecule is made in pairs within the group of 4. When it is finished, the 2 pairs from the same group of 4 exchange their 3D structures. Each pair has to check that the other pair’s molecule has no errors in its structure.

The students resolve how information is stored in DNA using the Socratic method directed by the teacher.

In Appendix 1 you will find a description of the teaching methods mentioned in this table.

Control: the construction of the three-dimensional model of the DNA molecule allows students to consolidate the concepts from the previous activity and check whether they have understood what the DNA structure is like or whether, on the other hand, there is an aspect they are still not sure about.

In addition, using the Number technique, there is a discussion, based on which the students can compare their answers with those of the other class members.

Co-evaluation: each pair of students constructs a three-dimensional DNA molecule and corrects what the other pair in the initial group of 4 has built.To make this correction easier, the students can use the Co-evaluation sheet.

You will find the tools mentioned here in the evaluation section.

TITLE: The biological functions of DNA

DESCRIPTION CONTENT COVERED

PROPOSAL FOR CLASSROOM TEACHING CONTROL AND EVALUATION TIMING

Based on seeing some animations they cover the replication, transcription and translation of DNA.

Once the 3 biological functions of DNA have been covered, the following aspects are emphasised:

The replication of a fragment of DNA (activity 8).

The meaning of expression of DNA (activity 9).

The expression of a fragment of DNA using genetic code (activity 10).

Finally, they see a video of these 3 DNA processes.

6. The biological functions of DNA.

Replication.

Transcription.

Translation.

7. Concept of expression of DNA.

8. Concept and use of genetic code.

The replication, transcription and translation of DNA are covered using the Puzzle technique.

So, each base group is formed by 3 students and each of them has to specialise in one of the 3 DNA processes. The specialisation process is carried out with the group of specialists, formed by 4-5 students. Depending on the total number of students in the group/class, there will be one or more in a group specialising in each of the 3 DNA processes.

When the students are experts on a topic, they go back to their base group and exchange the information with their fellow members. All 3 members of the base group end up understanding all the DNA processes.

The activities are carried out in the same groups of 3 and they are corrected jointly with the group/class using the Number technique.

The final video is seen by the whole group/class.

In Appendix 1 you will find a description of the teaching methods mentioned in this table.

Control: in the base groups, the students discuss what they have already covered with the group of specialists, asking questions about aspects they do not understand.This encourages students to control their own learning.

Carrying out activities 8 and 10 (after having covered the 3 DNA processes) helps students put into practice what they have just learned, making them aware of what they have understood and what they have not.

The discussion of the answers to the activities also allows each student to control his or her own learning.

Evaluation: the teacher corrects exercises 8, 9 and 10, giving a mark (forming part of the summative evaluation).

70 minutes*:

5 min for the contextualisation of the topic and the explanation of the dynamic

20 min for the specialists

TEACHING CONTROL AND EVALUATION TIMING

Activity 11. After seeing the video What is a gene? the students are asked to invent a gene for themselves, together with the function it could perform in an organism.

Activity 12 and 14. The students explain the diagram on the manipulation of DNA.They then see animations about this process and, finally, complete their initial explanation.

9. Concept of gene.

10. Concepts of genetic engineering (gene, DNA, restriction enzyme, PCR, amplification, duplication, protein, translation, recombinant DNA, special interest gene).

11. Characterisation of the transgenesis process.

The video What is a gene? is seen by the whole group/class together.

Each student then invents their gene and, using the1-2-4 technique, they discuss them with their fellow group members. The discussion with the group/class is carried out with the Plenary technique.

The explanation of how DNA is manipulated is made using the 1-2-4 technique.

The videos on the manipulation of DNA are seen together with the whole group/class. A few minutes are then left for complementing the previous explanation and, finally, a discussion is held on this process using the plenary technique.

In Appendix 1 you will find a description of the teaching methods mentioned in this table.

Control: exercise 12 explains a process to students who do not know much about it, so it is quite possible that some previously held ideas will be expressed. After finding out about the process through videos, they can modify and/or complement the explanation they gave earlier. In this way, by comparing what they knew before and after seeing the videos, they become aware of their own learning process.In order to demonstrate this to the students, the teacher needs to give an oral commentary.

LEVEL KEY STAGES 4 AND 5 TITLE: Laboratory practical: DNA extraction

DESCRIPTION CONTENT COVERED

PROPOSAL FOR CLASSROOM TEACHING

CONTROL AND EVALUATION TIMING

The idea of the practical is for the students to extract and see their own DNA. To do this they have two possible protocols: a simple one (carried out with domestic products) and a complex one (which can be found on the Xplore Health website). If the simple one is chosen, they have to complete exercise 15.

In all cases, the students will do the practical and answer questions in relation to what has happened and the application of this technique in real cases.

The teacher can make use of this practical to highlight aspects of the Nature of Science such as: working in a research team, the presence of women, etc.

12. DNA extraction process.

The laboratory practical is carried out in groups of 4 members, in which everyone has a role that they have to play throughout the practical. The 4 roles that have to be distributed among the students are as follows:

Researcher: the person who handles the materials and reagents.

Research assistant: responsible for making sure the protocol is strictly followed.

Secretary: takes care of making sure the questions on the protocol are answered while the practical is being done. Although everyone has to think about the answer, the secretary has to write it down.

Laboratory technician: in charge of providing the material the researcher needs.

If you wish, roles can be swapped during the course of the practical.

Evaluation: the students are asked for a practical report in which they basically explain the procedure followed, give reasons why each step is carried out and provide a response to the questions raised. To draw up the practical report, the model suggested in Appendix 1 of the student’s materials can be followed. Ultimately, as it is a practical in which nothing is investigated, the students merely follow a protocol for extracting and observing DNA, there are sections that cannot be filled in (such as the research question, the hypotheses, etc.).In all cases, it is up to the teacher to provide the practical with a research aspect by generating a question, hypothesis, etc.

This report is evaluated individually, using Rubric 1.

You will find the tools mentioned here in the evaluation section.

55 minutes*:

5 min for the initial explanation of the session

10 min for reading and understanding the protocol

30 min for doing the practical and answering the questions

Activity 19. The idea is that, through a computer game, the students should understand the relationship between DNA and biotechnology.

Specifically, using the virtual laboratory they can produce pharmaceuticals inside organisms (bacteria, animals and plants) and later check whether they have been able to manage to produce them in each case and in what quantities.

13. Genetic engineering techniques: introducing genetic material into an organism.

14. Use of organisms in industrial processes.

Depending on the conditions at the school (number of computers, etc.), they play the computer game individually or in pairs.

In the case of year 11 students, only the first phase of the virtual laboratory game is played. Year 13 students can play the three phases of the game, but they perhaps ought to finish it at home if time is short.

The question in exercise 19 is answered individually and afterwards they each discuss it with their partners.

Finally, the answers are discussed with the whole group/class.

TITLE: Conceptual map

DESCRIPTION CONTENT COVERED

PROPOSAL FOR CLASSROOM TEACHING CONTROL AND EVALUATION TIMING

Activity 20. The students summarise all the concepts, processes and techniques they have dealt with on a conceptual map.

All the content already covered.

The conceptual map is made in pairs following this methodology:

Each student makes an individual map (limited time).

Pairs are formed to discuss the two versions, exchange opinions, etc.

Finally, the pair makes a new conceptual map including the ideas of both group members.

When finished, the conceptual map is handed in and returned with a mark and comments for improvement. The teacher can also make another map and give it to the students so they have it as a model.

While the map created by year 11 and year 13 students follows the pattern of activity 20, the map created by the year 12 students is intended to be a summary of the teaching activity (as it is made at the last but one session of the proposed teaching sequence instead of doing it half way through, as is done by the year 11 and year 13 students).

Control: the summary activity of making a conceptual map allows the students to evaluate their own learning process. The working system (first individually and then in pairs) means it can be the students who, firstly, bring out their knowledge and, secondly, enrich their ideas based on exchanging knowledge with their partners.Finally, with the improvement comment that the teacher includes and the conceptual map they have as a model, they can complement their own map.

Evaluation: the conceptual map of each pair of students is evaluated according to Rubric 2. Optionally (and with a bonus of +X points) students can be offered the chance to hand the map in again after incorporating all the corrections.

Activity 21. Using a computer game, the students adopt the role of doctor and have the responsibility of giving each patient the best treatment depending on their disease and the symptoms they present.

In this way, they have to describe the action mechanism of some of the treatments and present them to the rest of the group/class.

Alongside this, they need to fill in the table in Appendix 2 of the student’s materials.

15. Types of pharmaceuticals and treatments provided by biotechnology.

16. Cancer:

18. AIDS:

Characterisation of the disease and of HIV.

Treatments.

The students play the computer game individually at home. The teacher suggests that they work with all kinds of treatments, but allocates a specific one to each student so they can study it in depth and explain it to the group/class.

With the allocated treatment, they have to make a poster explaining the action mechanism of the chosen treatment.

In class, the students share the information on their posters using the gallery technique.

So, in class, each student has the objective of filling in the Classes of pharmaceuticals available on the market table (Appendix 2 of the student’s material), bringing together the information presented overall by their classmates. Each student also answers any queries their poster has generated among classmates.

The session ends with a discussion.

In Appendix 1 you will find a description of the teaching methods mentioned in this table.

Control: thanks to the discussion after the gallery, the students have the chance to compare the information they have been compiling individually on the different kinds of pharmaceuticals with the overall comments of the group/class.

Evaluation: a co-evaluation activity is carried out in which each student has to evaluate another without that student knowing he/she is being evaluated. The co-evaluations are made following Rubric 3.

DESCRIPTION CONTENT COVERED

PROPOSAL FOR CLASSROOM TEACHING

CONTROL AND EVALUATION TIMING

This activity covers the current controversies around biotechnology.

Firstly, ethical, legal and socioeconomic questions related to biotechnology are drawn up.

A debate is then held based on a series of statements.

Then a video is shown expressing arguments for and against the previous statements.

Finally, the initial questions are asked again to see if anyone has changed their opinion.

24.Ethical and social implications of biotechnology.

25.Critical evaluation of the social and ethical implications of the use of stem cells.

26. Critical evaluation of the advances of biomedicine in the treatment of disease.

27.Argued evaluation of some contributions of genetics to human health: ethical dilemmas with early detection of genetic diseases and gene therapy.

The questions are asked by the teacher and written on the board. The students answer them individually.

The debate is held following the Dialogue game rules. Groups of 5-6 students are set up and 6 cards are given to each group.

Firstly, each group places the cards in a line running from the “AGREE” end to the “DISAGREE” end. This exercise creates debate in the group of 5-6 members.

Afterwards, the different groups compare the order in which they have placed the cards and there is once again a debate with the whole group/class.

They watch the video together.

The students ask the initial questions and alter them if they think it appropriate. There is a discussion of the answers.

In Appendix 1 you will find a description of the teaching methods mentioned in this table.

Control: the asking of a series of questions at the beginning and end of the activity makes it possible for students to become aware of the progression of their thoughts, as they have looked at the topic in greater depth (either using the video or exchanging opinions with their classmates). Under no circumstances must the initial answers be rubbed out. Instead, any answer will be positively valued, provided it is well argued.

Evaluation: the students self-evaluate and co-evaluate the group work and each member’s participation in the debate. Meanwhile, the teacher can also evaluate each student.Rubric 5 is used.

Justification of the rubric

This rubric has not taken account of some fundamental sections of a laboratory report (such as the research question, the hypotheses, the objectives, the results and the conclusions). Instead, because of the type of practical involved, more emphasis has been placed on the procedure and the justification of the steps.

Concerning the justification of the steps, it is highly desirable that the students should associate their prior theoretical knowledge with what is observed in the practical. For this reason, it is a good idea for the students to make predictions of what they expect to observe before actually carrying out a step, so they can then compare it with what they have actually observed and can give reasons for it with their theoretical knowledge.

Usage recommendations

Share the rubric with students to get them involved with the criteria being evaluated.

Evaluate the student both for the report itself and for his/her competences that have (or should have been) developed while drawing it up.

APPENDIX

The classroom teaching methods mentioned above are described below:

1-2-4

1. Within a base team, everyone first thinks individually (1) about the right answer to a question or task set by the teacher.

2. They are put into pairs (2) and exchange their answers, talking about them and improving them.

3. Finally, the whole team (4) has to decide on the best answer to the question or task set.

The number

The teacher sets the whole class a task. The students, in their base team, have to do the task, making sure that all the members know how to do it properly.

Each student from the class has a number (for example the one corresponding to them in alphabetical order). Once the time allocated for doing the task has elapsed, the teacher draws a random number from a bag in which there are as many numbers as students.

The student with the number drawn has to explain the task they have done to the whole class.

The Socratic method

The use of Socratic dialogue is intended to be an alternative to the traditional teacher’s explanation intended to encourage each student’s active participation in the progress of the class and particularly to help construct and put into practice dynamic mental representations (models) that gradually become more satisfactory and scientific.

The dialogue is intended to turn more or less accepted prior knowledge which is normally passive into more mature, more dynamic knowledge, allowing students to make inferences.

It is therefore the teacher who, by questioning one student, gets him/her to induce scientific concepts and give arguments. The teacher notices the difficulties students find in making the new knowledge their own and can help them by rephrasing the questions.

Socratic dialogue with one student in front of the others contributes to capturing the students’ attention, as they identify more easily with what their classmate does in response to the situations raised by the teacher than with any reasoning the teacher might present.

Dialogue alone is not enough to guarantee learning, but constitutes a tool for blazing a trail which must later be consolidated.

The puzzle

The teacher assigns the students to the base team (varied group). With 3 to 5 members. This can be the normal classroom working team, so it can even have a name in order to strengthen its identity.

Each member of the base team is allocated to a group of experts, which has to learn part of the unit or carry out part of the task. The teacher must therefore divide the information on the unit or actions of the task into as many parts as there are members of the base teams. That means, if the team consists of 4 students, the unit is divided into four parts and each member will be assigned to a group of experts on the corresponding part.

In the group of experts, each student must ensure that his/her classmates become experts, working in depth and in detail on the task set by the teacher.

Page 46: The biotechnology revolution - Xplore Health · Characterisation of the cell division process by mitosis. 20. Characterisation of the cell division process by meiosis. 21. Cell differentiation

TEACHING GUIDE / THE BIOTECHNOLOGY REVOLUTION / 46

Finally, the students return to the base team. The students explain the parts on which they have become experts to their fellow team members. The teacher controls the time and pace of the explanations and can offer support for students who need more help in giving their presentations. If students do not understand their classmates’ explanations, extra time may be given. Sometimes it can be a good idea if the teacher closes this phase with a general comment to the group/class making it possible to clear up doubts, expanding the content covered or giving examples.

The plenary

Discussion in which one of the members, representing the team of 2, 3 or 4 members selected at random explains the processes and results of their teamwork.

The other subgroups ask the group spokesperson questions and make comments. If time allows, all the teams can give explanations; if not, only those selected at random are called on.

The aspects the teams need to highlight and the ones that will be taken account at the end in the self-evaluation and the group evaluation must be agreed at the start.

The gallery

A positive social interdependence strategy, also known as the exhibition. It consists of placing the results of the students’ work (posters) in different places in the classroom and inviting the whole group to visit the exhibition, promoting the exchange of knowledge among the group/class.

Pencil in the middle

The teacher offers each team a sheet with as many questions or exercises on the topic worked on in class as members of the base team (generally, 4).

Each student has to deal with one question or exercise:

He/she reads it aloud.

His/her classmates provide information and express their opinion.

They check that everyone knows and understands the agreed response.

When a student reads “his/her” question out loud and everyone discusses what to do and decides on the correct answer, everyone’s pencils are placed in the middle of the table to indicate that at this point they can only speak and listen but not write. When everyone is sure what they need to answer in each exercise, they all pick up their pencils and write the relevant answer on their sheets. At this point, they cannot speak, only write.

Then they put their pencils on the table again and proceed in the same way, but with another question directed by another student.

The substance

This is a suitable structure for determining the main ideas (the substantial part) of a text or a topic.

The teacher invites each student in a base team to write a sentence about the main idea of a text or topic. Once this has been written, they show it to their fellow team members and the team discusses whether it is right; they correct it; they add shades of meaning, etc. They can also discard it if they consider that it is incorrect.

They then do the same with each of the sentences written by all members of the team.

As many rounds as are necessary are carried out with the group/class so that the key or substantial ideas emerge.

In this way, a summary is made of the key ideas on the topic.

Technique intended to promote participation in a large group. It is one of the best-known forms of the small group discussion method. It consists of dividing a large group into subgroups of 6 people who interact for 6 minutes.

They are used both to discuss any topic and to make participative decisions in large groups when it is not possible for each member to give his/her opinion.

The subgroups set up discuss the same topic or similar and complementary topics. Each subgroup chooses its spokesperson. It is often a good idea for each subgroup to draw up a summary of their point of view on a piece of paper or in a digital document which can then be shared so everyone can see it.
