Presents the Vector Knowledge Test that was designed to see if beginning physics students possess the minimal basic knowledge of vectors that will allow them to proceed with a study of Newtonian mechanics. Concludes that only one-third of the students in a calculus-based introductory course at California Polytechnic had sufficient vector…

The misconceptions related to the concepts of force and acceleration among college students are explored. Misconceptions are identified and their occurrence among a large percentage of students are observed. Provided are some implications for physics teaching and an eight-item test. (Author/YP)

Tests on diffusion and osmosis given to (n=116) secondary biology students, (n=123) nonbiology majors, and (n=117) biology majors found that, even after instruction, students continue to have misconceptions about these ideas. Appendix includes diffusion and osmosis test. (MKR)

Discussed are problems revealed in student responses to a practical task which formed part of an advanced level examination. The frequencies with which some misconceptions about cell reproduction and genetics occurred are presented. The nature of these misconceptions is analyzed and their implications discussed. (CW)

Examined are tenth-grade Western Australian students' conceptual knowledge of gravity and the motion of the planets. Students were interviewed with seven cards, and a four-item diagnostic test based on the interview data on the first four cards was developed. A total of 113 students' responses to the test are summarized. (YP)

Illustrated is the confusion over centrifugal force in sample problems, diagrams, formulas, and examples. Some recommendations to remedy the situation are suggested. (YP)

A questionnaire and demonstrations were used to identify students' conceptions about the composition of orthogonal velocities. Four questions from the questionnaire are provided and the results for each question are reported. The four implicit vector characteristics of this study are appended. (YP)

Described are the results of a conceptual physics survey given to a small group of high school physics students with the goal of identifying common misconceptions held by students. Three common misconceptions were identified and are discussed in detail. (CW)

This study was designed to identify students' misconceptions concerning frictional force, and Newton's laws of motion. It was also designed to determine the effectiveness of using instructions based on students' misconceptions to improve the teaching of physics. A pencil-and-paper test was administered to three groups of 16-year-old students:…

An investigation of Ontario high school students' understanding of acids and bases with quantitative and qualitative methods revealed misconceptions. A concept map, based on the objectives of the Chemistry Curriculum Guideline, generated multiple-choice items and interview questions. The multiple-choice test was administered to 34 grade 12…

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)

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)

Based on the premise that multiple choice tests can be used as diagnostic tools for teachers in identifying and remedying student misconceptions, this study focused on the development of an instrument for diagnosing secondary students' understanding of photosynthesis and respiration. Information is presented on: (1) procedures of development of…

Three purposes of this study were to: (1) propose some organizing theoretical and observational definitions of the anchor construct; (2) present some initial findings from a diagnostic test designed to uncover anchors for high school physics instruction; and (3) provoke an initial discussion of the new methodological issues that arise in this…

This paper describes the characterization of a student's framework of heat and temperature, and the development of a microcomputer-based laboratories (MBL) intervention program for grade 9 and grade ll students. The report presents the results of classroom study, including interview questions and answers and pretest/posttest, from experimental and…
