DeBoer, George E.; Quellmalz, Edys S.; Davenport, Jodi L.; Timms, Michael J.; Herrmann-Abell, Cari F.; Buckley, Barbara C.; Jordan, Kevin A.; Huang, Chun-Wei; Flanagan, Jean C. – Journal of Research in Science Teaching, 2014
Online testing holds much promise for assessing students' complex science knowledge and inquiry skills. In the current study, we examined the comparative effectiveness of assessment tasks and test items presented in online modules that used either a static, active, or interactive modality. A total of 1,836 students from the classrooms of 22 middle…

Development and Application of a Two-Tier Diagnostic Test Measuring College Biology Students' Understanding of Diffusion and Osmosis after a Course of Instruction.
Peer reviewed Peer reviewed
Odom, Arthur Louis; Barrow, Lloyd H. – Journal of Research in Science Teaching, 1995
Presents a diagnostic test for measuring college biology students' understanding of diffusion. Three general steps were used: (1) defining the content boundaries; (2) collecting information on students' misconceptions; and (3) instrument development. The split half reliability was 0.74, difficulty indices ranged from 0.23 to 0.95, and the…

Psychometric Models of Student Conceptions in Science: Reconciling Qualitative Studies and Distractor-Driven Assessment Instruments.
Peer reviewed Peer reviewed
Sadler, Philip M. – Journal of Research in Science Teaching, 1998
Reports on a study that uses psychometric modeling to rank the appeal of a variety of children's astronomical ideas on a single uniform scale. Findings support the view that alternative conceptions may be markers of progress toward understanding. Contains 82 references. (DDR)

Identification of Student Misconceptions in Genetics Problem Solving via Computer Program.
Peer reviewed Peer reviewed
Browning, Mark E.; Lehman, James D. – Journal of Research in Science Teaching, 1988
Describes a computer program presenting four genetics problems to monitor the problem solving process of college students. Identifies three main areas of difficulty: computational skills; determination of gametes; and application of previous learning to new situations. (Author/YP)

Development and Application of a Diagnostic Instrument to Evaluate Grade-11 and -12 Students' Concepts of Covalent Bonding and Structure Following a Course of Instruction.
Peer reviewed Peer reviewed
Peterson, Raymond F.; And Others – Journal of Research in Science Teaching, 1989
Outlines a procedure used to develop a written diagnostic instrument to identify misconceptions and misunderstandings of the chemistry topic. Reports the characteristic data for the instrument, and student understanding of covalent bonding and structure. (Author/YP)

Student Conceptions of Natural Selection and Its Role in Evolution.
Peer reviewed Peer reviewed
Bishop, Beth A.; Anderson, Charles W. – Journal of Research in Science Teaching, 1990
Discussed are the results of a test administered to nonmajor biology students on the topic of natural selection. The description of student conceptions, effects of instruction, and the effects of a belief in evolution are included. (KR)

Alternative Conceptions in Animal Classification: A Cross-Age Study.
Peer reviewed Peer reviewed
Trowbridge, John E.; Mintzes, Joel J. – Journal of Research in Science Teaching, 1988
Examined the extent to which students' alternative conceptions changed as a function of age. Reports that many alternative views remain intact throughout the school years. Provides several suggestions for teaching and research within the context of a neoconstructivist view of learning. (Author/YP)
