Computer as Tools
Tool for What?
Tool or “Fool”?
Give me some research and development money, I will
develop my great invention of writing. People can then……
Thot
The discovery of the alphabet will create forgetfulness in the learners'
souls, because they will not use their memories; they will trust to the
external written characters and not remember of themselves. Your
invention is not an aid to memory...you give your disciples not truth, but only the semblance of truth;
they will be the hearers of many things and they will learn nothing.
ThamusPlato: Pheadrus.
Is Writing Useful?
Do we forget things because of writing?
Tools for the complement of human mind
Writing What else?
Human Minds are limited
limited capacity of human short-term and working memory,
knowledge in long-term memory may not be well-organized
May not use some effective cognitive strategies
Writing

What expected ?
Tools that extend the human abilities
Cognitive Tools
mental and/or technological devices which support, guide and extend the thinking processes of their users
simplifies, rather than complicates the user's tasks aid the construction of knowledge by compensating f
or three major constraints of the human cognitive system: the limited capacity of human short-term and working mem
ory, the organisation of knowledge in long-term memory, and the learner's use of cognitive strategies.

Cognitive Tools
Internal: such as cognitive and metacognitive strategies
External, extend the thinking processes of learners. engage learners in more meaningful cognitive processing. used for the construction and facilitation of knowledge can be applied to mediate learning in most subjects. prece

Instruction versus Learning
Why mindtools but not CAI?
information or intelligence (in many different forms) is encoded visually or verbally
learners perceive the messages encoded in the medium and sometime "interact" with the technology
Interaction is normally operationalized in terms of student input to the technology, which triggers some form of answer judging and response from the technology in the form of some previously encoded (canned) message.
Technologies as conveyors of information have been used for centuries to "teach" students by presenting prescribed information to them which they are obligated to "learn."

Instructional Design Models

Objectivity:•Objective Reality •Common perception
Assumptions
Technology controlled by Experts
the process of learning is holistic. It cannot be understood by simply analyzing human responses to attributes of technologies that carry the messages to be learned.
In fact, it is difficult, if not impossible, to isolate the effects of the affordances of technologies.
Our instructional design models are grounded on two essential components of reality--objectivity and causality--both integral components of western consciousness.
Objective reality is predicated on a number of assumptions, such as commonality of perception which supposedly enables us to observe and describe the physical world and to convey those descriptions to others as reality.
Drawbacks of Instructional Model
Knowledge Construction, Not Reproduction
How we construct knowledge depends upon what the learner already knows which depends on the kinds of experiences that the learner has had, how the learner has organized those experiences into knowledge structures, and the learner's beliefs that are used to interpret objects and events that s/he encounters in the world.
Cognitive tools are tools for helping learners to organize and represent what they know. Constructivists claim that we construct our own reality through interpreting experiences in the world.
What is Learning? Constructivism: knowledge is built by the learner, not supplied by t
he teacher. The learner is actively engaged in interpreting the external world, but with social negotiation of meaning, i.e. common representations are shared with others. Mindtools facillitate this knowledge construction, in which learners organize and represent what they know. The learning processes of mindtools are active, creative, and student-controlled.
Reflective Thinking: involves inferences, implications, reasoning which requires some deliberation. Opposed to experiential thinking, which occurs automatically or reflexively during one's experiences in the world. Mindtools engage learners in reflective thinking, which leads to knowledge construction.
Constructionism: an extension of constructivism which states that the learner can especially construct his or her own knowledge when building an external or sharable product, such as a sand castle or a hypermedia computer project.
What expected from IT
To instruct someone to learn perform some activities which result in your under
standing of, and durable memory for, this material.
A cognitive tool gives the learner just such a ready made set of activities. Motivate students to learn actively
Difference between Instruction and the use of Cognitive Tools
Computer-based Cognitive tools
activate and perhaps model cognitive operations provide external resources that compensate for
the limited capacity of human memory. aid thinking, problem solving and learning by:
making large amounts of information immediately available for the learner's use,
making it easy to retrieve relevant, previously learnt information
prompting the learner to structure, integrate and to interconnect new ideas with previously acquired ones;
providing for self-testing, thus rehearsing the recall of previously learned information and thus increasing its retrievability;
enabling the learner to represent ideas verbally, pictorially and graphically;
providing for the easy movement, consolidation and restructuring of information needed by individuals as their knowledge base grows.
Rationales for Using Technology as Cognitive Tools
Designers as Learners 教學相長 Learners as Designers:
Students learn and retain the most from "mindful" engagement
cognitive tools require students to think mindfully in order to use the application to represent what they know
What are Mindtools
a way of using a computer application program to engage learners in constructive, higher-order, critical thinking about the subjects they are studying".
The learner enters an intellectual partnership with the computer and begins to access and interpret information, and organize personal knowledge in new ways.
Mindtools are computer-based tools and learning environments which serve as extensions of the mind.
Use of Cognitive tools
the traditional design and development processes are eliminated Technology given to the learner to use as media for representing
and expressing what they know. Learners function as designers using the technology as tools for
analyzing the world, accessing information, interpreting and organizing their personal knowledge, and representing what they know to others.
Distributing Cognitive Processing
Cognitive technologies are tools that may be provided by any medium and that help learners transcend the limitations of their minds, such as memory, thinking, or problem solving limitations (Pea, 1985). Example: Language, computer off-load some of the unproductive memorizing
tasks to the computer, allowing the learner to think more productively
Cognitive Tools
generalizable computer tools that are intended to engage and facilitate cognitive processing-
are both mental and computational devices that support, guide, and extend the thinking processes of their users
knowledge construction and facilitation tools that can be applied to a variety of subject matter domains.
students cannot use these tools without thinking deeply about the content that they are learning,
and second, if they choose to use these tools to help them learn, the tools will facilitate the learning process.
Practical Reasons for Using Mindtools
Lack of Software: available Computer Assisted Instruction materials only cover a fraction of the curricula.
Cost: purchasing even just a few CAI programs is very expensive.
Efficiency: a small set of mindtools can be used across the curricula. This is also more time efficient, because less time spent learning to use different programs.
Pedagogical Criteria for Evaluating Mindtools
The application can be used to represent knowledge.
Generalizable to content in different subjects. Engages learner in critical thinking about subject. Develops skills transferable to other subjects. Significantly restructures or amplifies thinking (provi
des alternative simple, powerful formalism for representing ideas).
Software should be learnable in 2 hours or less.

Generic Skills Acquired
the development of knowledge representation skills,
problem solving, planning and management of study, and students' self-monitoring and evaluation.
Graphical Organizers as Thinking Technology by Jamie McKenzie
Graphical Organizers convert complex and messy information collections into
meaningful displays. They compress. They focus. They make interpretation, understanding and insight much easier.
help keep students plan their research forays. They guide the gathering. They focus purpose. They show what is gained. They show what is still missing.
sometimes act like mind maps. They point to the destination. They identify related sites and sights.
