Chapter 5
This chapter focuses on how pedagogical theory
can be applied to tutoring systems in which the previous
chapters did not cover as extensively. Intelligent tutoring
systems are helpful for procedural tasks, but in complex
problems and situations, it is very difficult or nearly
impossible to find all of the solutions for that problem.
Also, many people feel that a tutoring systems should
facilitate and allow students to construct their own
knowledge, instead of actually forcing them down a solution
path and diagnosing student’s problem for them
(ex: ITS).
The author notes that tutoring systems should include
research on both cognitive psychology and instructional
theory. He then presents eight principles to abide by
in order for building a computer-based tutoring system
in which will include both these researches (cognitive
psychology and instructional theory). I think these
principles really give students more self-control of
their own environment while providing them with support
and collaborative learning. I thought HERON (a computer-assisted
learning system) is a great tool for students to learn
difficult and complex math problems. The visual (tree-like)
representation provides a very thorough breakdown of
the word problem. As I was reading one of the example
math word problems, I found it very difficult to solve.
But as I got a chance to look at the complete problem
in a visual tree-like structure (solution trees), it
started to make more sense and I eventually understood
how the problem was solved. Without it, it would be
much more difficult to solve. I think this software
can be very helpful for young kids to see how the problem
is broken down, because it allows them to actually visualize
all the pieces to the problem. Although HERON is not
an intelligent tutoring system, it does provide feedback
and detailed task analysis. It is also able to monitor
student activity by planning and creating a solution
tree. By allowing students to work on teams, this system
can work very effectively.
Chapter 6
This chapter focuses on pedagogic computer tools, specifically
Writing Partner. The author proposes that “no
tool is ‘good’ or ‘bad’ in and
of itself; the quality of the tool is a result from
and contributes to the whole Gestalt of events, functions,
and factors in the context of which it is being used”.
I think he makes a really good point. For example, let’s
say a person is preparing for a big race. Since the
race was going to be held on a flat surface road, he
decided to buy the best running shoes for flat surfaces.
But on the day of the race, he found out that the race
involved a lot of hiking and tough terrains. Although
the shoe is very good for flat surfaces, it does not
work as effectively in tough and heavy terrains. So,
in essence, the whole Gestalt of events (the big race),
functions (running shoes but for hiking purposes), and
factors in the context of which is being used has a
big impact on the quality of the tool (in this case,
the shoes).
The author also proposes that useful computers tools
for educational purposes should stimulate higher order
thinking and allow learners to think more freely and
independently. It seems as though the author opposes
intelligent tutoring systems (ITS), because it diagnoses
the problem for the learner and doesn’t allow
them to think and explore solutions on their own. He
wants a system in which will help the learner if he/she
gets stuck but does not implicitly tell them what to
do. It will also act as a partner in which both will
share different tasks. The computer tool will usually
do the lower level tasks such as computational operations,
while the learner will generate ideas and draw conclusions
to the situation or problem. I think this is a great
way for learners to think more critically and obtain
the knowledge more in-dept and also be able to retrieve
that knowledge much conclusively than having the computer
provide them with the solution to the problem (ex: ITS).
The computer tool, Writing Partner, acts as a partner
and helps the learner through the process of writing.
It goes through several processes such as planning their
stories, brainstorming, and outlining. The partner is
basically there to help the learner when they are stuck.
The tool does not necessary teach the learners to write
or corrects their errors. The learner does most of the
thinking and the partner (tool) is there to provide
them with guidance. I think this tool is very effective
for its purposes. But the only negative side is the
learner’s capabilities to generate ideas on their
own. Some learners find it very difficult to generate
ideas on their own, so it might not be as effective
on some learners. But I think it also depends on how
the tool is used in that particular environment. If
the tool is to be effectively implemented in classrooms,
then the classroom learning environment must change.
The tool does not work as effectively if the teachers
are still teaching the same way as if the tool wasn’t
implemented.
Chapter 7
This chapter discusses about knowledge design and how
hypermedia compositions can teach students instructional
design and also allow for a deep understanding of a
certain topic (in this case, the Civil War). The author
considers knowledge as a process of design (also as
a metaphor of design as well) and his methods of using
this approach are very interesting. The framework for
hypercomposition-based design is very similar to that
of the instructional design process. In his study, he
used 10 students and divided them up into two different
groups. One group was the overachievers (A students)
and the other group was the underachiever (C or below
students). Both group were required to do research about
the Civil War and eventually present it to the entire
class when they are finished. The results showed that
both groups showed teamwork, collaboration, and had
a much deeper understanding of the Civil War than the
other students that were not involved in the study.
I find this study to be very interesting. This type
of activity gives students much more control of their
own learning, which allows them to decide what goes
where, who should do what, how much information should
be covered, how it should be presented, and in what
order to present it in. I also think that students learn
more as well, because they know that they have to present
the information and are given a deadline, so they will
try to work harder and also try to find as much information
as possible on the topic.
Chapter 8
This chapter discusses collaboration and focuses on
qualitative modeling to enable learners to gain deep
knowledge on a particular topic. For this research,
they focused on learning velocity and acceleration.
Basically, they used two male students (15 years old)
and ask them to work together in solving problems on
a computer screen. Without knowing that the topic is
related to velocity and acceleration, the students
must try to figure out how to solve the problems that
are given to them. This is a very interesting study.
It really shows how much collaboration can help solve
abstract and difficult problems. The students discussed
issues among one another and really tried to solve
the problems by working as a team. I think complex
problem solving tasks is very difficult without having
any outside help. This brings me to a interesting question.
Does collaboration only happen in a synchronous environment
or can it happen with asynchronous environment? I can
see how collaboration can occur face-to-face, phone,
video conference, or chat rooms. But what about user-forums
or emails? I can see how collaboration can occur during
email replies and replying on user forums. For example,
let’s say I email a problem to an associate of
mine. He replies back with some of his thoughts and
ideas on tackling the problem. So, then I reply back
with him with my ideas on solving the problem. This
happens back and forth several times. In the end, both
of us shared our concepts and different views on the
problem. Wouldn’t that be considered collaboration
or not?
