Tasks |
|
|
Seven steps that comprise the learning design are: Observing
a chemistry phenomenon; describing and representing what is
occuring at the molecular level; discussing with a peer; viewing
an animation portraying the phenomenon at the molecular level;
reflecting with a peer; relating the molecular-level perspective
to the symbolic representation; and adapting the mental model
to a similar phenomenon...

|
|
|
|
| |
Resources |
|
|
Resources provided include: Lab-level phenomenon as a demonstration,
or on video/CD, or in the lab; VisChem molecular-level animations;
follow-up online multimedia...
|
| |
|
|
|
|
| |
Supports |
|
|
Supports provided include: the lecturer, a visual summary
handout to assist the students to understand the relationship
between the physical phenomenon, its molecular-level representation
and the symbolic notation...

Setting
Notes |
|
The learning design is currently implemented in a face-to-face
lecture environment, with students able to work in pairs and
with the support of an experienced lecturer to maintain focus
on key features, and facilitate discussion...
|
| |
|
|
|
| |
Outcomes |
|
Build scientifically-acceptable mental models of substances
and reactions at the molecular level; relate these models
to the laboratory level and symbolic level in chemistry; apply
their models to new substances and reactions;...
|
| |
|
|
|
| |
Assesment |
|
Students are required to use the three-thinking-level approach,
and draw molecular-level representations, in lab classes and
in their reports for assessment...
|
| |
|
|
|
| |
ICT
Contribution |
|
The initial use of ICT was to produce and present the VisChem
animations in a constructivist teaching strategy, whilst requiring
a skilled educator to guide the process...

Pedagogy
Notes |
|
The educational foundation for this learning design is based
on combining three models for learning...
|
| |
|
|
|
| |
History |
|
The need for the VisChem animations became apparent from
a frustration with teaching students about the 3-D, dynamic
molecular world using 2-D, static teaching resources...
|
| |
|
|
|
| |
Evaluation |
|
A Ph.D study by Rebecca Dalton has focused on the evaluation
of the VisChem animations and their effectiveness in assisting
students to build mental models of the molecular world...

Designer
Debrief |
|
The learning design works very well if the essential features
of the design are implemented...
