Steps in the TAR ProcessTeaching foundational knowledgeCreating objectives for students learningDeveloping hypothesis for practices that
enable students to achieve the learning objectives
Defining measures of successDeveloping and implementing teaching
practices within an experimental designCollecting and analyzing dataUsing data to guide teaching practiceReflecting, evaluating, and iterating

Typical (Conventional) Organic Chemistry Classroom SettingStudents attend class and are bombarded with
new materialsStudents are expected to revise lecture notes
and do additional readingOccasional post-lecture quizzes are givenA few exams are given, lumping lecture
materialsFinal exams are cumulativeStudents are given an overall class grade
based on their quiz and exam performancesAbout 50% of class earn F, D, W

Project Goals/ObjectivesTo apply the TAR steps in generating a project
that involves the use of technology to enhance teaching and learning
To encourage pre-lecture reading via pre-lecture quizzes
To conduct weekly surveys to integrate technology into pedagogy
To collect evidence for the impact of pre-lecture quizzes on student performances
To use the data obtained from the surveys as guidance in the re-lecture of a specific concept and to monitor students’/professor’s progress

About 65% earned A,B, or C at the end of the semester, as compared to about 50% in a typical organic chem class
![Page 20: Yakini Brandy, Shimelis Hailu, Pogisego Dinake, Folahan O. Ayorinde Howard University Presented at The 238 th American Chemical Society National Meeting](https://reader034.vdocument.in/reader034/viewer/2022042822/56649e9f5503460f94ba2085/html5/thumbnails/20.jpg)
Online pre-lecture quizzes are useful in forcing students to read the lecture material
Pre-lecture posting, quizzing and post lecture surveys facilitate Teaching-As-Research as a result of proactive assessment and reiteration.Enable students to engage in active learning in the classroomChanges students’ studying behaviorGive professor more time to cover course content
Effort should be made to inform students of the importance of maintaining survey integrity.Learning outcome surveys would be skewed if different
students take the initial and final surveys The survey project is still ongoing in the organic
chemistry class to improve the teaching practices and learning experience of the students and professors.
