Examined alternative conceptions of animals and animal classification by interviewing fifth grade, eighth grade, and freshmen/sophmore college students (N=62). Subjects were asked to name five animals, state critical attributes, and complete a classification task. Results indicate all ages fail to generalize and discriminate among examples and…

Describes three studies in which students (N=515; N=60; N=135) were asked to indicate appropriate operations and numbers used in solving open mathematical sentences. Analysis of data and interviews suggest two error patterns: "finding a solution" and "inverse operation." Indicates that "finding a solution" strategy can be corrected with…

Surveys 11 inservice teacher centers to provide activities for the improvement of teacher effectiveness in the critical academic areas of science, mathematics, and language arts. Reports 54 ranked needs of science teachers. Lists teacher and school demographic characteristics. (MVL)

Reports that young children in the pedestrian accident prone age range of four-eight years hold a variety of naive conceptions regarding speed. Proposes a primary science unit using a conceptual change approach. (MVL)

Discusses aspects of using anecdotes in the classroom including vividness, the downside, high inferential risks, and low inferential risks. Reviews research underpinnings. (MVL)

Describes a study in a large metropolitan high school to ascertain what influence the use of regular writing in algebra classes would have on students' attitudes towards algebra and their skills in algebra. Reports the simpler and more direct the writing topics the better. (MVL)

Notes that as the student progresses through school, science experiences hold a less positive view. Used are teacher interviews and classroom observations conducted to determine possible explanations. Points out that schools need to help students realize how much science affects their everyday lives. (MVL)

Describes and synthesizes the findings of 11 case studies which comprise the Exemplary Practice in Science and Mathematics Education Study. Reports four assertions in which exemplary teachers used strategies for management, encouraging students to participate, increasing understanding of science and math, and maintaining a favorable classroom…

Provided is a unit which relates the fulcrum of a lever system and the mean of a distribution of scores. The objective, rationale, two student laboratories, and an evaluation system are outlined. Content background on statistics is offered. (MVL)

Three computer programs for the Apple II family are reviewed: (1) "Super Vocab Machine"--vocabulary self-tutorial; (2) "Elements, Compounds, and Mixtures: A Matter of Mystery"--database for the elements; and (3) "That's Life: Human Body Exploration"--information about the human body. (MVL)

Investigates similarities and differences of science and mathematics teachers' teaching practices related to critical thinking. Compares the two groups of teachers in terms of objectives and assessment techniques, teaching preferences, various activities, and use of cooperative groups. Reports the results for all of 53 items. (YP)

Presented are three cases for intuitive understanding in secondary and college level geometry. Four ways to develop the intuition (physical experience, mutable manipulatives, visualization, and looking back) step are discussed. (YP)

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)

Examines the students' understanding of mathematical structure and the relationship between problem solving and the identification of the structure in 13 word problems. Multidimensional scaling and hierarchical cluster analysis were used to assess how subjects organized word problems in their minds. (YP)

Investigates the effects of verbal fluency and curiosity in deductive or inductive treatment on tests dealing with various species interactions. Reports that neither psychomoter or written curiosity measures interacted significantly with any of the treatments and that eighth graders with good verbal ability did significantly better in the…
