Abstract

Analysis of the effect of course structure, including motivational tools, laboratory and how problem solving was presented in lecture on students' exam performance, attitudes toward the subject of chemistry, and problem solving strategy use. Exam performance indicates that the use of ressurection points on the final exam benefits students' learning, especially for the Middle Bottom quartile of students. Laboratory improves students' understanding when the exams correspond to laboratory content. Attitude differences, as measured by the Attitude toward the subject of chemistry inventory version 2, show some differences and the influence of the level of expertise in graduate student teaching assistants. The use of dimensional analysis to solve stoichiometry problems in lecture leads students to use that process to solve novel tasks in a similiar way, even if it is not efficient or effective. The students' familiarity with the content,as well as the problem solving process, influence how they solve tasks.
