1 Shimelis Hailu Howard University Impact of Blackboard on Students Academic Performance and Teaching-as-Research in an Organic Chemistry ClassShimelis HailuHoward 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 theassigned 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 • Quizzes METHOD Participants Assessment Measurements ► 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

15 • Changes student studying behaviour 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 learningthrough diversity.• Enables students to engage in active learning• Changes student studying behaviour
16 ► Absence of in-class time for pre-lecture quizzes 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
