Describes an investigation of first-year chemical engineering students' understanding of the mole concept. Finds that a series of activities designed to provide students with visual or experiential points of reference for the mole concept had a strong positive effect on student misconceptions. Contains 16 references. (Author/WRM)

Reports on the findings of a research project involving decimals and students' misconceptions about them. Offers some practical activities that may help children understand decimals better. (ASK)

Multiple choice questions are a common method of assessing student understanding. In this article, the authors discuss and evaluate a student-focused collaborative learning strategy for working with such questions that results in greater student learning and allows instructors to better understand student thinking and ultimately to write better…

This paper describes a sequence of lessons from two Calculus I classes for teaching the epsilon-delta definition of a limit. In these lessons, the author elicited students' misconceptions and perceptions of this definition through a reading/writing lesson and then used these student ideas to design a lesson aimed at addressing these misconceptions…

Physicists have known for some time that pendulum motion is a useful analogy for other physical processes. Chemists have played with the idea from time to time but the strength of the analogy between pendulum motion and chemical processes has only received prominent published recognition since about 1980, although there are details of the analogy…

The implications of history and philosophy of chemistry are explored in the context of chemical models. Models and modeling provide the context through which epistemological aspects of chemistry can be promoted. In this work, the development of ideas and models about acids and bases (with emphasis on the Arrhenius, the Bronsted-Lowry, and the…

The persistence of students' misconceptions about motion illustrates the enormous difficulty that teachers face in their attempts to overcome these with traditional physics instruction. An understanding of students' ideas about motion and ways to incorporate them into successful instructional approaches can be obtained from an analysis of…

The author cites research from students' misconceptions of decimal notation that indicates that many students treat decimals as another whole number to the right of the decimal point. This "whole number thinking" leads some students to believe, in the context of comparing decimals, that "longer is larger" (for example, 0.45 is…

Affirmative action, a controversial topic about which students have many misconceptions, lends itself especially well to a sociological analysis. This paper describes an approach to teaching that: (1) informs students of different affirmative action programs; (2) gives them the opportunity to apply and integrate a variety of concepts and research…

The 10th International Conference on Educational Data Mining (EDM 2017) is held under the auspices of the International Educational Data Mining Society at the Optics Velley Kingdom Plaza Hotel, Wuhan, Hubei Province, in China. This years conference features two invited talks by: Dr. Jie Tang, Associate Professor with the Department of Computer…

This paper describes research conducted in a classroom devoted to conceptual change instruction. The teacher in this class of fifth grade students at a midwestern parochial school made explicit attempts to have her students comment on the conceptions they held, their justification for those conceptions, and the status they attached to their…

Fact-filled textbooks that stress memorization and drilling are not very good for teaching students how to think mathematically and solve problems. But this is a book that comes to the rescue with an instructional approach that helps students in every grade level truly understand math concepts so they can apply them on high-stakes assessments,…

Discusses strategies for overcoming common student misconceptions. Strategies include using pretests followed by teaching techniques planned to contrast new information with students' previous ideas; using pretests followed by time for students to question ideas and test their knowledge; and giving students a real-world task that can only be…

Argues that surveying what new students understand about the basics of a subject can be illuminating. Presents a case study of A-level chemistry students and suggests that, although the details of what was uncovered are idiosyncratic, the paucity of understanding of fundamental concepts may be common. Presents suggestions for responding to such a…

Reports on research into the cognitive basis of children's alternative conceptions regarding light and sight. Highlights three factors that were found to interfere with effective teaching in science and suggests ways teachers can modify their approaches to circumvent them. Discusses ambiguity and the role of language, experience and concepts, and…
