This study examined the effect of formal and concrete instruction upon science achievement and intellectual development of sixth grade students. Formal instruction, which emphasized oral and written language, included lecture, discussion, oral quizzes, written assignments, reading assignments, films, film strips, written tests, and quizzes.…

Investigated relationships among attitudes toward science, interest in science, science curiosity, and self-concept of science ability. Data, obtained from 228 sixth-grade students, show that attitudes toward science, interest in science, and science curiosity are highly related. Implications of these findings for science instruction are…

The conceptual frameworks of Thai children (n=48) related to causes of health and sickness were analyzed using the "Interview-about-Instances" and the "Conceptual Profile Inventory" techniques. The results indicate that Thai schoolchildren hold considerable personal knowledge about the causes of health and sickness that does…

The purpose of this study was twofold: (1) to understand the conceptual frameworks that sixth-grade students use to explain the nature and structure of matter and molecules; and (2) to assess the effectiveness of two alternate instructional units in helping students change those conceptions. The study involved 15 sixth-grade classes taught by 12…

This paper describes the development of a sixth-grade "Matter and Molecules" unit using a new curriculum development model based on conceptual change research, the field testing of this unit in 15 classrooms and the field test results. The development process and the resulting unit are contrasted with the unit's predecessor, the "Models of Matter"…

This study analyzed the differences in attitude and achievement of fifth- and sixth-grade subjects presented with a series of science lessons directed toward instructional procedures which addressed the right hemisphere, the left hemisphere, or both hemispheric processing modes. The study used 65 randomly selected students divided into four…

The effect of pictures on reading comprehension under different levels of text organization was investigated. Sixth graders (N=132) read three science passages, presented with or without pictures representing text content. Picture condition was crossed with three levels of text organization. Multiple-choice test scores were analyzed using reading…

Conducted a study (n=26) to test descriptions about learning associated with open-ended design projects and to clarify the notion of ownership of resources and practices. Reports that conceptual and material resources were shared among students and that tool-related practices were appropriated as newcomers participated with more competent others…

Microcomputer-based laboratories (MBL), the use of microcomputers for student-directed data acquisition and analysis, represents a promising new development in science laboratory instruction. This descriptive study determined the impact of MBLs on middle school students' understanding of graphs of distance and velocity. The study was based on the…

The question of how children solve force and motion problems in computer simulations without explicit knowledge of the underlying physics was investigated. Keystroke sequences made by children were saved and analyzed, and children were interviewed to understand their perception of the relationship between keyboard input and on-screen action. (CW)

Examined is the role of middle school science textbooks in dealing with sensitive social and scientific issues. Ten widely used textbooks are compared to determine the amount and depth of content presented on five major global issues, including nuclear weapons. Implications are discussed within the context of a television culture. (KR)

The purpose of this study was to investigate the effects of the 4MAT instructional system on achievement and attitudes in science. Fifty-four academically gifted sixth grade students in three schools in the Chapel Hill-Carrboro (North Carolina) City Schools were randomly assigned to two groups, a 4MAT group and a Restricted-Textbook group that…

The middle school years can be important for developing student attitudes about learning, school, and careers. However, it is often difficult to involve parents in working with middle schools to help adolescents form positive attitudes toward school and science. This exploratory study investigates a method of potentially having all of a teacher's…

Describes the effects upon the attitude and achievement of a group of below average sixth grade readers generated by enriching the language arts curriculum from a literature base to a science base. Results indicate that attitude did not improve overall, but the achievement measure increased for 12 of the 17 students. The attitude survey is…

Reports on student attitudes toward science-technology-society (STS) after visiting a science-technology museum and considers what variable factors of the visitation impacted these attitudes. Results indicated that significant differences in attitudes were present between visiting and nonvisiting students and between grade levels. (TW)
