Although taxonomic proficiency is a prerequisite for understanding ideas central to biology, previous research has established that learners frequently misclassify animals by not following the tenets of accepted taxonomic rubrics. This has immediate relevance with the recently revised English National Curriculum now requiring concepts of animal…

This article reports on a study that was designed to describe prospective elementary teachers' prior verbal and diagrammatic knowledge about various aspects of light, seeing, shadows, and mirror images. Data were collected through individual interviews using simple apparatus. Included are some inferences about how students' ideas may have emerged…

Among the conclusions from an microanalysis of 29 high school physics student's concept mapping behaviors were that concept maps lead to sustained discourse on the topic and improved declarative knowledge. On the negative side, concept maps let scientifically incorrect notions become ingrained and go unchallenged. (PR)

This research used semistructured interviews to investigate students' (n=32) understanding of electrochemistry following a 7-9 week course of instruction. Three misconceptions were identified and incorporated with five previously reported into an alternative framework about electric current involving drifting electrons. Also noted was the tendency…

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)

The experimental/analogy group scored significantly higher than the control group on a posttest question that required the definition of diffusion (n=77 community college students). Hypothetico-deductive reasoning skill was significantly related to correct application of the diffusion concept to a change from the misapplication of the polarity and…

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…

Investigates South African teachers as a possible source of pupils' erroneous ideas about respiration. The views of 136 teachers were elicited by means of an analysis of how teachers marked an essay containing errors commonly found among year-12 students. Teacher responses suggest that many of them as well might have erroneous ideas. (PR)

Data were collected via semistructured interviews on female college students views about the natural world. Fundamental beliefs are presented as a concept map and characterized by bipolar descriptive codes. The most intriguing observation of the study was science's apparent lack of influence on students' beliefs about nature even though these…

Identifies misconceptions related to the fundamental characteristics of atoms and molecules held by twelfth-grade students. Data were obtained by administration of semistructured interviews to a stratified, random sample of 30 students. Fifty-two misconceptions were observed and reported. Some of the misconceptions identified parallel the…

Students' understanding of the concept of relative speed is described. A variety of ways of understanding relative speed and of viewing a problem that dealt with this concept were uncovered. The results are used to suggest ways for teachers to proceed in assisting students to enhance their understanding of relative speed. (PR)

This study found no significant relations between junior high school students' (n=50) prior alternative frameworks on energy and their cognitive levels of operation. Significant differences in learning outcomes were achieved by students (n=29) who had higher cognitive level scores. The extent to which students succeeded in learning the energy…

This article aims to present the results obtained from science teachers about their attitudes toward students' conceptions and the use of teaching strategies based on these conceptions. The results may contribute to the planning of inservice courses. (Author)

This article reports on answers by children (grades 1-9, n=83) to oral and written questions concerning the phase change from liquid to gas. The development of concepts was followed, proceeding from concrete to abstract ideas. Many students were found to experience difficulties in problem solving even though they may have had the necessary level…
