Ben, a good mathematics student, participated in a seven-week study. Describes three tasks that reflect impact of textbooks, real-life connections, and mathematical symbols. Shows that Ben's notion of one-half was task-dependent, concrete, and based on physical actions. (NI)

Considered are two commonly used techniques, the interview and word association techniques. Highlighted is a third technique called the repertory grid. This third technique can be used to interpret students' knowledge based on an explicit, psychological theory of human behavior. (Author/CW)

The focus of this document is on students' understanding of symbolization processes in algebra, and specifically their understanding of semantically laden letters. In the first four sections, four inappropriate ways in which many college students use semantically laden letters are described. Evidence from clinical interview protocols demonstrate…

Interview data exemplify students' attempts to integrate the concepts of electrochemistry with related knowledge that they had previously constructed or acquired in other classes. The implications for minimizing potential misconceptions center on the difficulties students experience when using more than one model for explaining scientific…

Compares the effect of weak, flexible, and rigid family structures on the cognitive development of 61 Scottish and 40 Pakistani school children in Glasgow, Scotland. In a problem-solving test, children from flexible environments outperformed those from either weakly or rigidly structured homes. This difference was reflected in the school…

Discusses the frequent misconception displayed by students that chromosome structure is a function of chromosome number or ploidy. Provides detailed analyses of the evidence concerning the prevalence of this ploidy/structure misconception among students of introductory genetics and the potential sources for inaccurate communication that it can…

The second in a series of manuals on adults with learning disabilities, the booklet covers assessment techniques. The nature of assessment as an ongoing process is stressed, and the role of observation (both systematic and nonsystematic) and interview data are discussed. A seven-step evaluation sequence is proposed, with the major goal of…

This project was designed to produce a program evaluation and needs assessment of the 1982 Alberta Elementary School Mathematics Program in terms of cognitive level comparisons between student responses and curricular demands. Assessment procedures consisted of 14 individual interviews and 8 paper-and-pencil tests based on children's responses to…

Identifies the unsophisticated assumptions and conjectures, both intuitive and empirical in character, underlying secondary school science students' (n=25) portrayal of scientific knowledge and its production. Structured interview protocols explored not only the students' substantive knowledge base but, perhaps more important, their ability to…

Interviews with 72 mixed ability students, aged 7 to 12, about arithmetic problem-solving strategies, indicated that the preference between procedural and deductive strategies becomes a divergent reality across ability levels. Among the conclusions is that more able children tend to be doing a qualitatively different sort of mathematics than their…

A study interviewed 6 grade-6 students after participation in 21 lessons on basic concepts of fractions and decimals to determine how different children construct rational number concepts. Discussed the formation of the key concept of equivalent fractions based on student responses to interview questions. (MDH)

Reports results of procedures directed at isolating and identifying students' difficulties in comprehending the concepts involved in lessons about gas exchange and respiration. Indicates that pupils (n=137) had deficient understanding of prerequisite concepts and tended to operate at the concrete operational level, whereas the highly abstract…

Correlates 46 Dutch high school students' attitudes toward nuclear war, sexism, ethnocentrism, and authoritarianism with their moral judgment level. Finds political attitudes related to moral judgment level. Qualitative data was obtained from interviews with 19 of the 46 students further develops the relationships. (CH)
