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 this article, the authors describe how classroom observations were used to characterize differences in instructional practices among undergraduate science courses. Student and faculty behaviors and dialogues were quantified using the Teaching Dimensions Observation Protocol (TDOP) in introductory science courses across multiple disciplines…

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…

Introductory science courses serve a population of students in the major (i.e., chemistry) as well as those students outside the discipline (i.e., premed, biology, engineering). In an effort to help this diverse population of students connect personally with the content of the course, we sought ways to include student-centered activities, provide…

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…

Science teaching and learning can be made both engaging and student-centered using pedagogical, computer-based learning tools. We have developed self-paced interactive problem-solving tutorials for introductory physics. These tutorials can provide guidance and support for a variety of problem-solving techniques, as well as opportunities for…

Student performance in lecture-based versus case study-based instruction was compared in this study. Case-based teaching that emphasized problem solving and discussion significantly improved student performance on exams throughout the semester and enhanced students' abilities to correctly answer application- and analysis-type questions. (Contains…

This article describes an interdisciplinary course that develops essential mathematical modeling skills within an introductory biology setting. The course embodies recent recommendations regarding the need for interdisciplinary, inquiry-based mathematical preparation of undergraduates in the biological sciences. Evaluation indicates that the…

Describes the use of supplemental instruction in an introductory chemistry course designed for freshman nursing students and explores its impact on student performance and response to the program. Results indicate a positive impact of supplemental instruction and its popularity with students. Contains 22 references. (JRH)

Students crave problem-solving strategies that promise increased achievement on tests. Student ambitions seem to align with teacher goals, yet students resist using these strategies for various reasons. We seek to establish a pedagogy modifying student behavior so they are more likely to use any strategy a teacher deems useful. (Contains 1 figure…

The National Inquiry Standard for Science Education Preparation requires science teachers to introduce students to scientific inquiry to solve problems by various methods, including active learning in a collaborative environment. In order for science teachers to comply with this inquiry standard, activities must be designed for students to…

Discusses the lack of study skills found among non-science majors. Provides examples of how science courses differ from other courses. Gives some methods to help students study more effectively. (MVL)

Points out that college freshmen expect major changes in the academic environment as they move from secondary school. Recommends that faculty use this opportunity to show students how to think for themselves. (DDR)
