Technology and the Large Class Bill Vining Department of Chemistry and Biochemistry Celebration of Teaching, November 2

1. Dealing with a large class? Technology can help: • Tablet computer develops material as you go and • records entire lecture. Students who miss class • can watch the lecture online and then come in • with questions. • Clicker use during class aids communication betweenyou and your students, and between students. • Online homework can serve as to keep students upto date with material and you up to date withtheir progress. TABLET COMPUTERS use a pen to write on the screen during a lecture presentation. Record the entire Lecture: video of screen + voice . ONLINE HOMEWORK (OWL) serves to: Give automatically graded homework Provide 1st-level tutorial help Act as a mastery system Provide students an indication of their progress and randomized study examples Provide you data on: - student progress - time spent working on HW - warning reports of all students below a certain level - quick communication with groups of students based on progress Technology and the Large ClassBill Vining Department of Chemistry and BiochemistryCelebration of Teaching, November 2009 PowerPoint saves the handwritten notes made on slides. You can post both original and annotated versions. Student response is highly favorable. Question: How does this method of lecture delivery compare with normal PowerPoint use? CLICKERS use student-held response devices where they “vote” on questions you ask. Uses: Attendance Quick check on understanding Keeping class attention In-Class quizzing Getting student opinions Drive class discussions Producing and posting a recorded lecture takes about 30 minutes of computer time, but only ~2 minutes of work. Students were asked (via clickers) which aspects of the course best helped them learn the material. Homework was found most useful; the physical textbook least useful.
