Computational thinking (CT) is a way of making sense of the natural world and problem solving with computer science concepts and skills. Although CT and science integrations have been called for in the literature, empirical investigations of such integrations are lacking. Prior work in natural selection education indicates students struggle to…

In the United States, research on beginning science teachers provides little guidance regarding empirical minimum levels of discipline-specific science coursework for sufficient subject matter knowledge to teach science. Accordingly, in this study we analyzed secondary physical science teachers' science coursework for subject matter knowledge…

There is a concern that materialistic thinking--meaning the tendency to attribute a set of matter-like properties to nonmatter concepts--is one of the central barriers that students face in the journey toward understanding scientific concepts. The cross-sectional study presented here used the Sound Concept Inventory Instrument (SCII) (Eshach,…

This study aims to identify students' misconceptions regarding covalent bonds. Seventy-seven graduate students in the middle of Indonesia participated in the study. Data were collected in three stages. First, misconceptions were identified by using the Semi Open Diagnostic Test. Ten students who experienced the worst misconceptions were…

The connection between the molecular-level structure of a substance and its macroscopic properties is a fundamental concept in chemistry. Students in college-level general and organic chemistry courses were interviewed to investigate how they used structure-property relationships to predict properties such as melting and boiling points. Although…

Despite concerted efforts by science educators to understand patterns of evolutionary reasoning in science students and teachers, the vast majority of evolution education studies have failed to carefully consider or control for item feature effects in knowledge measurement. Our study explores whether robust contextualization patterns emerge within…

The purpose of this study was to examine the ways in which elementary teachers applied their understanding of conceptual learning and teaching to their instructional practices as they became knowledgeable about conceptual change pedagogy. Teachers' various ways to interpret and utilize students' prior ideas were analyzed in both epistemological…

Ninth- and 10th-grade students (n=310) participated in a study designed to determine the effect of three variables (viewing a demonstration, engaging in student to student discussion, and/or reading a refutational text) on conceptual change in physics. Results revealed that reading the refutational text helped students change their intuitive ideas…

This study was based on the framework of the "conflict map" to facilitate student conceptual learning about causes of the seasons. Instruction guided by the conflict map emphasizes not only the use of discrepant events, but also the resolution of conflict between students' alternative conceptions and scientific conceptions, using…

This study questions the effectiveness of a traditional teaching-by-example technique when used with students who hold misconceptions. Interview techniques were used to explore students' (n=21) responses to two different uses of examples and to provide indications of student reasoning. Results indicate that when students hold a misconception,…

Criticizes an article by Browning and Lehman (1988) for (1) using "gene" instead of allele, (2) misusing the word "misconception," and (3) the possible influences of the computer environment on the results of the study. (PR)

Authors respond to criticisms by Smith in the same issue and defend their use of the term "gene" and "misconception." Authors indicate that they did not believe that the use of computers significantly skewed their data concerning student errors. (PR)

Reports the relationship between student characteristics and results of a test of misunderstanding administered to 49 suburban high school students enrolled in a New York State Regents Chemistry Class. A multiple regression analysis of data revealed that the best predictors of performance on the posttest misunderstanding test was the pretest score…

Explores the relationships between seventh-grade students' misconceptions of genetics and natural selection and four cognitive variables: reasoning ability; mental capacity; verbal intelligence; and cognitive style. Reports that only the reasoning ability was significantly related to the number of misconceptions. (Author/YP)

Discusses the correctness of the directions of acceleration at various points in a pendulum problem shown in Reif (1987). Provides the author's responses to the comments on the problem. (YP)
