Langley, Dorothy; And Others – Journal of Research in Science Teaching, 1997
Investigates the conceptions and representations of light propagation, image formation, and sight typical to preinstruction learners (N=139). Findings indicate that preinstructional students display some familiarity with optical systems, light propagation, and illumination patterns and have not developed a consistent descriptive and explanatory…

Ritchie, Stephen M.; And Others – Journal of Research in Science Teaching, 1997
Examines which of the warrants of authority, coherence, and empirical evidence were invoked by grade 8 science classroom participants in their daily interactions, and whether these were linked to particular teaching referents. Results indicate that when the teacher embraced a context exposure referent at the expense of constructivism, the warrant…

Eryilmaz, Ali – Journal of Research in Science Teaching, 2002
Investigates the effects of conceptual assignments and conceptual change discussions on high school students' achievement and misconceptions about force and motion. Analyzes pretest and posttest data from the Force Misconception and Force Achievement Tests (FMFAT). Discusses the effects on the conceptual change discussion on reducing…

Haidar, Abdullateef H.; Abraham, Michael R. – Journal of Research in Science Teaching, 1991
High school chemistry students' (n=183) applied and theoretical knowledge of dissolution, diffusion, effusion, and states of matter were compared. Study found that students' formal reasoning ability and their preexisting knowledge are associated with their conceptions and use of particulate theory. A significant difference between applied and…

Huddle, P. A.; Pillay, A. E. – Journal of Research in Science Teaching, 1996
Analyzes students' attempts to answer examination questions involving stoichiometry and chemical equilibrium and reports that the majority of the students do not fully understand either concept. Concludes that the main difficulty with these topics is that they are highly abstract and first taught to students before they have reached the stage of…

Garnett, Pamela J.; Treagust, David F. – Journal of Research in Science Teaching, 1992
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…

Brown, David E. – Journal of Research in Science Teaching, 1992
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,…

Gussarsky, Esther; Gorodetsky, Malka – Journal of Research in Science Teaching, 1990
Word associations were used to map high school students' concepts of "chemical equilibrium" and "equilibrium." It was found that the preconception of the two concepts was differentiated on noncritical dimensions. (Author/CW)

de Berg, Kevin Charles – Journal of Research in Science Teaching, 1995
Investigation of (n=101) 17- to 18-year-old students' responses to a task relating to Boyle's Law for gases found that 34% to 38% of students did not understand the concepts of volume and mass, respectively, of a gas under the given circumstances. (Author/MKR)

Westbrook, Susan L.; Marek, Edmund A. – Journal of Research in Science Teaching, 1991
Examines seventh grade life science students, tenth grade biology students, and college zoology students for understanding of the concept of diffusion. Describes the differences among the grade levels in sound or partial understanding, misconceptions, and no understanding. Discusses the effect of developmental level on understanding. (KR)

BouJaoude, Saouma B. – Journal of Research in Science Teaching, 1992
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…

Harrison, Allan G.; Grayson, Diane J.; Treagust, David F. – Journal of Research in Science Teaching, 1999
Focuses on cognitive and affective changes that occurred in one student during the study of heat and temperature. Initially the student's conceptual framework was undifferentiated with regard to heat and temperature; however, course activities and concomitant use of concept substitution helped the student differentiate these concepts and integrate…

Lee, Gyoungho; Kwon, Jaesool; Park, Sang-Suk; Kim, Jung-Whan; Kwon, Hyeok-Gu; Park, Hac-Kyoo – Journal of Research in Science Teaching, 2003
Develops an instrument for measuring secondary students' cognitive conflict levels as they learn science. Indicates that cognitive conflict consists of four constructs: (1) recognition of an anomalous situation; (2) interest; (3) anxiety; and (4) cognitive reappraisal of the conflict situation. Discusses implications for instruction and…

Lawson, Anton E.; Thompson, Lois D. – Journal of Research in Science Teaching, 1988
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)
