An Inquiry/Technology Based Approach to Introductory Chemistry
Video demonstrations:Video demonstrations are macroscopic
demonstrations of chemical phenomenon. Students will be able to collect qualitative
and/or quantitative data with the aid of an activity guide to assist the student
in collecting, analyzing and interpreting the data. The activity guide will
consist of instructions for the student to follow and questions for them to
answer based on their review of a video. The activity guide can be hard copy,
in which case the student would complete the answers to the questions and turn
it in, or the activity could be a form on the web that integrates the video
with the questions. The student follows the instructions, watches the video
and answers the questions. In either form, written or on the web, the activity
can be done individually or as cooperative group investigation. The video demonstrations
can be viewed on the Web independently by the students, in groups, or during
a lecture/discussion class.
Here is a draft example of a video demonstration. The example is drawn from
chemical equilibrium. In the video demonstration students watch several videos
and answer questions related to what they observe. Again the activity could
be used in a variety of ways; as a pre-lecture inquiry activity (the students
do the activity before the material is covered in lecture), as an in-class activity
(discussion between the students and instructor in lecture), or as a homework
assignment (done following a discussion of chemical equilibrium). However the
video demonstration is used students could work on it indivdually or as a small
group.
Please not in the sample provided on the CD-ROM that the form feature will
not work properly. In order to work properly the files must be running froma
web server. The example on this CD-ROM uses links to move from page 1 of the
activity to page 2. You will receive an error message if you click on the Submit
