This paper describes an introductory biology course for undergraduates that heavily incorporates quantitative problem solving in activities and homework assignments. The course is broken up into a series of units, each organized around a motivating biological question or theme. Homework assignments address the theme or question, and typically…

In large, introductory courses, instructors and teaching assistants often struggle to provide detailed feedback on student homework in a timely manner. Here we describe a peer-reviewed homework system that provides quick turnaround while offering flexibility in the construction of homework problems. Homework is administered through a cycle, which…

Studying physics for nonphysics majors at college level is usually a process of learning new problem-solving skills and sometimes seems a frustrating experience. In an attempt to provide students with more learning resources, online homework was required to supplement the instruction. This study reveals the role of the online homework assignments…

New technological developments have minimized training, hardware expense, and distribution problems for the production and use of instructional videos, and any science instructor can now make instructional videos for their classes. We created short "Khan style" videos for the topic of buffers in biochemistry and assigned them as…

To improve students' retention rates in general chemistry, online homework was introduced into our curriculum. Replacing quizzes directly by online homework significantly improved (p less than 0.0005) success rates in second-term general chemistry. Attitudinal Likert survey results indicate that the majority of students completed the online…

A homework problem that can be graded quickly, involve students in problem solving, and provide feedback on their problem-solving ability is described. A two-part homework problem is assigned: part one stated in the usual manner, and part two consisting of a description with segments left blank for students to fill in. (Author/JN)

Examines student success in a freshman chemistry course that involves students who are at risk of failure. (Contains 14 references.) (YDS)

Suggested are ways that problem solving can be integrated into existing college courses. Modification of assignments, reduction of class examples, developing the structure of knowledge, finding time to teach process skills, and developing student awareness are discussed. A self-assessment form for students is included. (CW)
