The overall goal of our work is to disrupt pervasive narratives and misplaced assessments of what defines scientific brilliance, specifically in the introductory chemistry classroom. The traditional design of science, technology, education, and math (STEM) courses perpetuates the narrow view that intelligence is characterized by innate talent,…

Holly Hiscox was concerned that many of her A-level students -- asked to evaluate three different historical interpretations for their non-examined assessment task -- still tended to hold unhelpful misconceptions about the nature of interpretations. In this article she explains how she created an introductory scheme of work to help them understand…

Courses: The exercise is designed for an introduction to public-speaking course or a "basic course" with a major public-speaking assignment. Objectives: By the end of this activity, students will be able to (1) identify their own misconceptions about public speaking, (2) recognize the relevance of public-speaking skills to their career…

The K-W-L method of teaching is a simple method that actively engages students in their own learning. It has been used with kindergarten and elementary grades to teach other subjects. The authors have successfully used it to teach physics at the college level. In their introductory physics labs, the K-W-L method helped students think about what…

Acceleration is a fundamental concept in physics which is taught in mechanics at all levels. Here, we discuss some challenges in teaching this concept effectively when the path along which the object is moving has a curvature and centripetal acceleration is present. We discuss examples illustrating that both physics teachers and students have…

We tested the effectiveness of hands-on nighttime laboratories that challenged student misconceptions, using a new assessment exam to measure learning in a nonmajor introductory astronomy class at Rensselaer Polytechnic Institute. We were able to increase learning at the 8.0 sigma level on one of the Moon phase objectives that was addressed in a…

Identifies some of the erroneous and misleading statements discovered in the three-volume middle and junior high school integrated science text, SCIENCE Interactions. (ZWH)

Supplemental instruction classes have been shown in many studies to enhance performance in the supported courses and even to improve graduation rates. Generally, there has been little evidence of a differential impact on students from different ethnic/racial backgrounds. At San Francisco State University, however, supplemental instruction in the…

Presents results of a study examining how introductory economics students use graphic analysis. Concludes that the difficulties students have in analyzing an economic problem graphically result from problems with concept formation. Suggests that videotaping can assist instructors to understand and anticipate the learning processes that students…

Maintains that having students estimate the size and width of a class waste paper can (placed on a desk) is a simple and effective way of illustrating perceptual distortion. Tests show that people will consistently overestimate the height of the can, allowing for a useful discussion on sensory distortion. (MJP)
