Over half of the 101 preservice elementary teachers studied accepted inductive arguments as valid mathematical proofs, while over 60 percent accepted correct deductive arguments. Over one-third simultaneously accepted inductive and deductive arguments. More examples of the limitations of empirical evidence and of the power of mathematical proof…

Three important elements needed for constructing expert mathematics lessons are described: rich agendas, consistent but flexible lesson structures, and clear, understandable explanations. Each is discussed in terms of its hypothetical characteristics and then tested by comparing two novice and four expert elementary mathematics teachers. (MNS)

Students at concrete or formal operational reasoning levels made similarity judgments on geometric concepts and mathematical expressions on ratio, proportion, and similarity. Clear prototypical maps could be derived for both groups. Formal operational students structured subject matter content significantly more like subject matter experts than…

Studied were the misconceptions that preservice elementary teachers have about multiplication and division. Results indicated that they are influenced by the same primitive models as students; the most common errors made by both groups are quite similar. (MNS)

This aptitude-treatment interaction study explored the relationship between cognitive restructuring ability and treatments varying in the amounts of teacher guidance on tasks with fractions. An interaction was found between cognitive restructuring ability and levels of teacher guidance for items having continuous perceptual distracters. (MNS)

Investigates whether introduction of music reading activities during beginning instrumental music instruction impedes student's development of aural musicianship and instrumental performance skills because of the division of attention between aural and visual activities. Concludes that music reading activities do not adversely affect the…

Examines group influences regarding music preferences to determine the effect that conformity has on the decision-making process. The study tested participants selections of popular and orchestral excerpts which had altered pitch and/or tempo. Concludes that preferences of music majors regarding orchestral music are not significantly affected by…

Studies reliability of the Measures of Creativity in Sound and Music (MCSM), a test developed by Cecilia Wang. Compares the MCSM scores with subjects' academic achievement scores, sex, and age with music and classroom teacher ratings of subjects' creativity. Concludes that research is still needed to define a theory of musical creativity, define…

Examines the relative effects of the five practice conditions of modeling, singing, silent analysis, free practice, and control on instrumentalists' performance. Finds significant differences in subjects' performance of correct rhythms, phrasing or dynamics, and tempo, and insignificant differences among performances of correct notes and…

Examines the professionalization of high school cheerleading, investigating the impact of a national association which establishes cheerleading standards and is involved in cheerleader selection. Finds that the increased status and skill associated with this national organization results in a bureaucratization of cheerleading and usurpation of…

Examines the effect of economics instruction on ninth-grade student attitudes toward economic topics using the Economics Values Inventory. Finds that economics instruction has a measurable impact on student economic attitudes and reinforces developmental trends resulting in greater commitment to the system of economic production and diminished…

Explores the reliability and validity of an affective domain instrument, the "Survey on Economic Attitudes," by providing new norms and a discussion of the properties of the national sample of high school students used. Presents current information about the economic attitudes of U.S. high school students and raises some important questions about…

The effects of teaching strategy, relevant knowledge, and strategy length on high school students' mathematical learning ability were studied. Performance was found to increase as levels of relevant knowledge increased. Characterization strategies were found to be more effective than exemplification strategies for students with high relevant…

Classroom interactions of seventh-grade girls and boys who differed in confidence in their ability to learn mathematics were compared. Boys were involved in more public interactions with their teacher than girls. High-and low-confidence students differed very little in their interactions with the teacher. (Author/DC)

This study investigated the relationship between mathematical performance and mathematics self-efficacy, attitudes toward mathematics, and the choice of mathematics-related majors by college women and men. Performance and self-efficacy correlate positively with attitudes, masculine sex-role orientation, and a mathematics-related major. (Author/DC)
