1 Impact of Blackboard on Students Academic Performance and Teaching-as- Research in an Organic Chemistry Class Shimelis Hailu Howard University

2 INTRODUCTION: Role of quizzes in class activities Post-lecture Quizzing is an established method for increasing students learning An alternative method for quizzing is Pre-lecture approach to increase the likelihood that students read the assigned material

3 Project Goals/Objectives Collect evidence for the Impact of pre-lecture online quizzes on students performance. Improve students academic performance. Facilitate coverage of course content.

4 METHOD Participants Data was collected using Blackboard technology from an Organic Chemistry II course ( N= 60) at Howard University. Because of pre-lecture posting, more attention is given to the more difficult materials in class lectures. Assessment Measurements Quizzes Exams Time spent on reading pre-lecture materials

5 Hits Percent Up to exam From exam 1 to exam From exam 2 to exam Comparison on 1 st, 2 nd and 3 rd exam

6 Was reading pre-lecture document helpful? Average grade on the 1 st exam was out of 200 grade point. number of quizzes taken no. of stud. greater than average A total of 53% of students are equal to or greater than average in this 1 st exam.

7 27% of students are those who didn't take or took one time 73% of students are those that took two times or three times No. of quizzes taken Percent above average grade

14 Effect of pre-lecture online quizzes on reading the lecture material before class. No. of quizzes taken Hits Hits per student

15 CONCLUSION Online pre-lecture quizzes are useful in forcing students to read the lecture Material. Pre-lecture posting and quizzing facilitates Teaching-as- research as a result of proactive assessment and learning through diversity. Enables students to engage in active learning Changes student studying behaviour

16 Conclusion contd. Absence of in-class time for pre-lecture quizzes The relative ease with which instructors could incorporate them into a course The increased efficiency of students time
