Objectives
Biology is the study of living organisms.
It seems that this subject is so big that there are a lot of facts
for students to memorize.
However, studying biology is not as difficult as many students think.
To learn about the inside of the body and how different parts
work is very exciting!
Together with the recent development of information technology,
students can become much more actively involve in
the learning processes.
Therefore, Power Point, Internet and other technology are used
in this lecture to produce text, graphics, video and
animation to try to make studying the types of
blood vessels, the structure of the heart and
the like easier and more enjoyable.
Characteristics
1/ Nowadays in Hong Kong, to avoid virus transmission,
any experiment requiring the use of human blood cannot be
performed in school laboratory.
Therefore, compatibility of any two blood types cannot be tested
in real time.
This academic multimedia package allows this dangerous experiment :
Human Blood Group Experiment, to be simulated in a classroom
or in a laboratory,
thus enhancing in-class activities and capturing student attention.
2/ The heart beat is demonstrated in the Heart Video so as to show the
size of the real human beat and the ‘lub’ and ‘dup’ sounds clearly.
3/ Biological key words’ pronunciation are recorded.
4/ The content page allows teachers to focus on process,
collaborative writing.
5/ Parts called checkpoints are given in each section can help students
grasp and remember the main ideas and concepts.
Use these to emphasize what students need to learn and thus can be
used to evaluate the teaching or learning processes.
6/ Independent learning is facilitated when students connect their
personal computers to the Internet and using this package.
This powerpoint can serve as self-review after lesson.
7/ Use the linked homepage to monitor education related listservs on
the Internet.
This keeps teachers and students in touch with the current trends.
Provide a channel for students asking question independently and
at home.
8/ Homework is given at the end of the unit.

User guide
1/ PC requires the QuickTime for Windows and the Sound Application.
2/ Run the program after putting the msvbvm50.zip file into
‘ \windows\system\ ‘ through the unzip program.
3/ It is recommended for students to work in the groups.
4/ At the beginning of each page is a key question, which relate
the content of the next page.
Teachers are recommended to ask students to answer these before
going to the next part.
