Help tutors understand the course
Can review/learn content
Can share ideas, explanations and
strategies with colleagues
10. Pre-Calculus Study
1st year students had weak pre-calculus
knowledge
Posted mini-clips 3 weeks before a
diagnostic test
289 engineering & science students
189 males, 100 females
11. Results - Overview
Frequency of Use
Mini-clips visited 4681 times
Average time per visit was 6 min (358 sec)
Usefulness
87% of students rated mini clips as useful or
very useful
12. Results - Survey

14. Conclusions
Students liked using mini-clips
◦ Easy to use
◦ Control over use
◦ Helped learning
◦ Better than just text
Use of mini-clips was positively correlated
with perceived change in students
knowledge
15. Practical Implications
Mini-clips are a viable, useful resource to
help student learning
Potential to save time
More closely match current student’s
learning style
17. Future Research - Resources
Future Research
