Using “YouTube” in Calculus I

1. Using “YouTube” in Calculus I Using pre-lecture video technique to increase class participation in calculus I

8. Understanding everything • They are too confused to ask any question • They do not even know what to ask • There are other factors, for example, some students are shy to speak out in the classroom setting.

9. Why so confused??? Forget pre-calculus materials Break of study May be some topics skipped in pre-calculus Other reasons include “lack of motivation”, “laziness”, “don’t care mentality” etc

10. Post pre-lecture videos on blackboard • All students must watch it before they come to the lecture. That is why it is called pre-lecture video • Each video is approximately 10 minutes long based on some specific topics • Usually topics are selected from pre-calculus. This will refresh their mind on that particular topic. • For example, students watch the video on the factoring of trinomials and the next day I gave lecture on the finding limit using algebraic approach. Believe it or not approximately 50% of the students have problem factoring – a topic in remedial math course.

11. What I get out of it?

12. What I get out of it? • Students are getting less confused in the lecture

13. What I get out of it? • Students are getting less confused in the lecture • Students are more focused during the lecture.

14. What I get out of it? • Students are getting less confused in the lecture • Students are more focused during the lecture. • Class participation triple. From 2/3 students to 9/10 students. Still low for a class size of 30 students but at least this is an improvement.

15. What I get out of it? • Students are getting less confused in the lecture • Students are more focused during the lecture. • Class participation triple. From 2/3 students to 9/10 students. Still low for a class size of 30 students but at least this is an improvement. • More students asking questions about the calculus part of the lecture instead of the basic things.

16. Advantages • Spending less time explaining basic stuff

17. Advantages • Spending less time explaining basic stuff • Students are more prepare to understand the lecture

18. Advantages • Spending less time explaining basic stuff • Students are more prepare to understand the lecture • More participation means more encouragement for me

19. Advantages • Spending less time explaining basic stuff • Students are more prepare to understand the lecture • More participation means more encouragement for me • Sometimes students learn more that one way of solving a problem – one from the pre-lecture video and the other from the lecture

20. Advantages • Spending less time explaining basic stuff • Students are more prepare to understand the lecture • More participation means more encouragement for me • Sometimes students learn more that one way of solving a problem – one from the pre-lecture video and the other from the lecture • Students like to watch instead of reading. This may not be a good thing but it is the reality

24. Disadvantages

25. Disadvantages • How to make sure all students watch the pre-lecture video that is posted?

26. Disadvantages • How to make sure all students watch the pre-lecture video that is posted? • Sometimes in the video wrong information is posted. So you need to watch the entire video before posting it in the blackboard

27. Disadvantages • How to make sure all students watch the pre-lecture video that is posted? • Sometimes in the video wrong information is posted. So you need to watch the entire video before posting it in the blackboard • Not all has high speed internet in their home and some do not even have a computer

28. Disadvantages • How to make sure all students watch the pre-lecture video that is posted? • Sometimes in the video wrong information is posted. So you need to watch the entire video before posting it in the blackboard • Not all has high speed internet in their home and some do not even have a computer • Technical difficulties

29. This is a very individualize experience • It may not be appropriate for other subjects and other colleges Thank you
