Presents science investigations that involve some challenging mathematics related to proportional reasoning. Can be embedded in thematic, interdisciplinary units to reinforce understanding of specific proportions, provide practice in proportional thinking, or assess abilities in solving problems that involve proportions.

Studied black five-year olds from a school in an impoverished urban area (n=32) and white five-year olds from a blue-collar suburban area (n=32) for their school achievement at the end of kindergarten. The same cognitive intervention was attempted with children from both school populations. Discusses research methodology and research findings. (KW)

Describes a study of faculty at Tennessee Technological University regarding their teaching styles and perceptions of student deficiencies and necessary study skills content. Indicates that faculty cited critical thinking, personal responsibility, time management, and problem-solving skills as essential and reported that students lacked critical…

Investigates the effect of mental schemes corresponding to additive and multiplicative situations in the process of interpreting and solving problems. Classifies relative difficulties of problems according to their situations which are considered through a written test administered to pupils in grades 2, 3, and 4. Supports the assumption that…

A study involving 36 British children with autism, 21 children with severe learning difficulties, and 54 controls found correlations between false belief and subtractive reasoning tasks; however, results indicate ability in subtractive reasoning was a necessary but not sufficient component of successful performance in the false belief tasks.…

Explains the importance of an integrated science class setting in students' ability to engage in decision making and develop skills required to design investigations. Presents an example of a science classroom in which students participate in a guided inquiry activity and design an investigation. Points to the potential of group projects in…

Presents activities on insects for second grade students. In the first activity, students build a butterfly garden. In the second activity, students observe stimuli reactions with mealworms in the larval stage. Describes the assessment process and discusses the effects of pollution on living things. (YDS)

Assesses the combined effects of goal setting and different types of comparative information on fourth-grade students' (N=84) self-efficacy and fraction skill, particularly within a Taiwanese classroom. Results reveal that children in the self-referenced groups demonstrated significantly higher fraction skill and self-efficacy than did children in…

Examines gender differences in EXPLORE scores of gifted third through sixth graders. Results reveal that boys performed better on Mathematics and Science reasoning, and girls performed better on Reading, but effect sizes were negligible. Test performance of boys in mathematics was somewhat stronger than that of girls, but results favoring girls in…

Explains the game of Oware, an African board game that provides rich opportunities for all children to build and extend arithmetical ideas and number sense, develop strategic thinking, and explore important social behaviors. (Contains 22 references.) (ASK)

Focuses on learning difficulties in procedural knowledge, and assesses the procedural difficulties of grade 12 and first- and third-year university students based on common sense reasoning in two areas of chemistry--chemical equilibrium and geometry, and polarity of molecules. (Contains 55 references.) (Author/YDS)

Uses a methodology for probing systems-thinking developed and used to investigate the way children (N=35) think about the natural environment. Findings suggest that eight-year-old children are capable of this type of thinking. (DDR)

Compares a group of expert cancer researchers with four groups of fourth year medical students (the "novice" groups) engaged in the task of designing a clinical trial to test a new cancer drug using a computer-based modeling tool, the Oncology Thinking Cap. (Contains 24 references.) (Author/YDS)

An instructional program focused on story theme was administered to 2nd and 3rd graders in a high-poverty school. Compared with traditional instruction, the program improved theme comprehension and identification of instructed themes in new stories. However, the program did not help students apply a theme to real-life situations or identify and…

Describes the role of an instructional sequence and two accompanying computer-based tools in supporting students' developing understandings of statistical data analysis. Documents the emergence of the sociomathematical norm of what counts as a mathematical argument in the context of data analysis. (Author/MM)
