MPTL11

Background

• 1999 – reform of Polish educational system performed,• ICT introduced into the core curricula of science,• 1999 – 2004 - all secondary schools equipped with

computers - used mostly for learning of basic ICT skills,• no improvement of the quality of science education,

because: - lack of good educational software and laboratory

equipment, - low level of teachers’ competencies at the effective use

of ICT, • 2003 , on 5th December - decision of EU Council promoting

an efficient use of ICT for education.

MPTL11

• Taking these into account we created the network of 3 Universities (Poznan, Bialystok and Torun) working on enhancing the efficiency of teaching with the use of ICT.

MPTL11

Structure of the Multimedia Mini - Laboratories Network

• each university collaborates with the group of 10 – 15 science teachers (physics, chemistry and biology),

• the effectiveness of methods and tools in process of science teaching and learning is quite well documented in the literature (for example: Rogers, Pinto, Pecori, Sassi, Frost, Lavonen, Demkanin, Mioduszewska, Ellermeijer, Turlo et al.),

• teachers are elaborating the examples of ICT methods and tools applied to science teaching and learning,

• the results of their work are discussed and applied by other teachers within the network.

MPTL11

Steps of the Project’s execution

• Planning of propositions based on literature and teachers’ classroom experience, which reflects students’ misconceptions,

• the assumed educational objectives are the mostimportant for selection of the topics,

• financial support was provided by the National Ministryof Education,

• schools were equipped with some necessary hardware(interfaces, sensors, video cameras, etc.) and appropriatesoftware – mostly COACH, produced by CMA Amsterdam,

• local training courses for teachers were organised, the first onewas taking place in Poznan (see picture).

Examples of the first teachers’ project results from Kujawsko-Pomorskie Region

Let’s present some examples of the project results from 2004:

MPTL11

1. Physics and astronomy curriculum at the lower secondary school aided by experiments driven by Coachlab II and software Coach 5 (by MSc. Stanislaw Niedbalski). This is a mature proposition of complete list of MBL school experiments correlated with the school textbook edited by „New Age” (in Polish „Nowa Era”) and aimed at increasing the efficiency of teaching and learning.

I. Physics

2. Studies of magnet falling down in tubes made from different materials.

MSc. Tadeusz Kubiak showing the experiment MPTL11

The MBL investigations of strong magnet falling down in plastic, copper and aluminium tubes allow:

• to study the changes of magnet motion parameters (velocity and acceleration) and evaluate the g value,

• to compare the motion parameters for magnet falling down in the gravitation field (inside a plastic tube) with a motion inside diamagnetic (copper) and paramagnetic (aluminium) metal tubes,

• to verify the induction phenomena (caused by induction of electromagnetic force inside a metal tubes) and Lenz’ principle.

The obtained results allow students to withdrawn conclusion, that the plants have to respire also at the night (in darkness).

5. Monitoring of germination and fermentation processes (by MSc. Piotr Felski).

Furthermore, precise analysis of the achieved data permit to find the relation between O2 and CO2 concentrations. The plants respire using the oxygen and dose out CO2 in proportion 1:1.

The other biological experiments are related to oxygen process of plants germination and non-oxygen – alcoholic fermentation.

In the first experiment we can observe the results of germination of pea in darkness during 2 days.

Changes of oxygen and CO2 concentrations during pea germination in darkness.

Thus, germination is the oxygen process, when oxygen concentration decreases, concentration of CO2 increases.

In this experiment students can verify what are the effects of different medicaments on different diseases, as stomach over - acidity or pain.

International SOCRATES Cominius Project:Effective Use of ICT in Science Education (EU ISE)

Initiation

The initiators of EU ISE Project at the meeting in Kopenhaga (from the left: Peter Demkanin, Jozefa Guitart,

Bob Kibble, Jari Lavonen, Jozefina Turlo)

MPTL11

The Project’s rationale

According to an OECD (2004) survey, the use of ICT in education in most countries concentrates on sporadic and mechanical information retrieval from the Internet.

Therefore, the main goal of project EU ISE is to collect the best practices on the integration of ICT into science education, that can also motivate students and teachers and improve the quality of science teaching and learning.

These best practices can demonstrate how ICT use can make science education more versatile and goal-oriented, inspire students active and creative self-learning, promote co-operation and study in authentic contexts.

Objectives: 1. To identify the best practice of using different methods and tools of

ICT in science education across Europe, propose system for benchmarking this area,

2. designed and test a course for in-service and pre-service teacher training in such way.

MPTL11

Target Groups: Teachers of science in schools age 10-18 and trainee teachers of science. Lecturers with responsibility for in-service and pre-service teachers training

Main activities:1. Identification of the bet practices (based on literature and the examples of the

effective use of ICT in school).2. Creation of a training module for teachers.3. Organisation of the international workshop for teacher trainers on EU-ISE.

The first activity International Questionnaire for teachers: „Making the use of ICT in science

teaching” (http://www.fizyka.umk.pl/test/data.php) Until now the Polish partner collected about 90 answers (60 from women and

30 from men, among them more than 50% of physics teachers) We got some answer to the questions: when, for what and in which way the

ICT methods and tools are used in science education. But we are still collecting more data and planing the international comparison of the results

MPTL11

Further activities

Creation of the national extended network of science teachers and giving information about the Project.

MPTL11

Experiments with the use of Ultrasound motion detector

• inexpensive detector working with continuous, coherent wave of 40 kHz frequency, working with microcontroler PIC 16C84 and memory EEPROM,

• aimed at investigation a position, velocity and acceleration of the moving bodies,

• measuring the distance with the resolution below 0.2 mm, time with the resolution of 300 s,

MPTL11

Discussion the teacher solutions during the consecutive meetings

MPTL11

• As the result within three last editions of this competition we got more than 110 papers with interesting propositions from the field of physics, biology, chemistry and environmental education.

• Some science teachers propositions have been already checked in school practice as the ecological refrigerator shown below.

Additional Polish activity

General Polish competition on Multimedia Aided Science Experiments

MPTL11

Dissemination of the Project results

• Some multimedia aided experiments were presented by Krzysztof Sluzewski to school students from other european countries.

• The best teacher solutions have been presented during the workshops of the Polish Association of Science Teachers on: How ICT is used in science education? organised by us in the year 2005 (Opole) and 2006 (Warszawa).

MPTL11

• In the next steps we would like to extend our Miltimedia Mini - Laboratory network to whole Poland!

Thank You for your attention!
