Although making errors in the learning process is common, it is usually perceived by students as something negative and a potential threat to self-esteem. Such perception often prevents students from considering errors as learning opportunities. By using errors as integral elements of the learning process within the science classrooms, and…

Students in introductory college science courses often have a simplified understanding of the scientific method. To introduce students to the complexity of the scientific process and the value of empirical observations, I implemented a semester-long assignment that required introductory-level college science students to build and calibrate weather…

Half of students who start college pursuing a degree in science drop out of the sciences by their senior year. This is due, in part, to low attendance and lack of preparation by the students. The failure to develop instructional strategies that actively engage students in science, however, is also a marked factor. A crucial need to reform how…

The authors explored whether a new pedagogy using personal response systems (clickers) along with case study teaching improved students' perceptions of their understanding of science in large introductory biology classrooms. Twelve faculty from nine institutions and 1,457 students across the United States and Canada participated in this study.…

Attitudes toward science may develop as early as middle school and often differ between genders. Do these gender-based differences in attitude persist into the college years? In a survey of 376 university students, male students reported a stronger self-concept, more motivation, and more enjoyment of science than did female students, and female…

Peer-led team learning (PLTL) has been widely adopted for enhanced learning in a variety of disciplines, mostly in introductory chemistry, but also in organic chemistry, as in this study (Tien, Roth, and Kampmeier 2002). This pedagogical approach forms student groups led by students who have previously done well in the course (standard peer…

This study is an analysis of the effectiveness of a faculty-designed laboratory experience about a difficult topic, cellular respiration. The activity involves a hands-on model of the cellular-respiration process, making use of wooden ball-and-stick chemistry models and small toy trucks on a table top model of the mitochondrion. Students…

Most of the research on case-based science teaching at the university level involves comparative studies, which contrast student perceptions of case-based science teaching with more traditional teaching. Sometimes this type of research is being done to convince colleagues that case-based science teaching is equally effective if not better than…

College students often struggle to understand complex technical language inherent in scientific communication. In some cases, this struggle leads to plagiarism. We performed a statistical analysis to find which teaching strategies are best suited to significantly reducing plagiarism in science courses. (Contains 1 table and 7 figures.)

This case teaches students to be skeptical of "scientific claims," especially those that are sensational and fall outside the boundaries of normal scientific explanation. Students read the case scenario and then evaluate data to determine whether they believe there is enough scientific evidence to confirm the existence of extrasensory perception.…
