Most students enter their first formal science courses with intelligently conceived and sophisticated concepts of science. Some of these may be compatible with the principles of modern science, but others may be incorrect, inadequate, outdated, or otherwise unacceptable. Conceptual frameworks based on intuitive misperceptions, naive inferences,…

Traditionally, illustrations used in instruction have been concrete in nature with the learning outcome not always considered in the design of the illustrations. This study investigated whether concrete or abstract illustrations were more effective for supporting acquisition of abstract concepts in print media when evaluated by immediate and…

Knowledge representations and mental models from graphically presented information were investigated for 98 college students with different levels of mathematics experience. The subjects were drawn from a remedial algebra course (n=35), a second semester calculus course (n=35), and a calculus-based statistics course (n=28); they were all exposed…

This study explored the relationship between conceptual level, a social cognitive variable, and second language communicative competence. The subjects were female secondary school students in five second-year French classes. The research hypotheses stated that conceptual level was related to the development of communicative competence while…

Research is reviewed on second language learning and implications for student assessment and placement of limited English proficient (LEP) students in special education are addressed. To support her contention that the most effective mode of instruction for an LEP child requiring special education should be within the framework of the child's own…

This study concerns children's understanding of spatial relationships and their expression in drawings and photographs. Sixty children (ages 5, 8, and 11) were asked to discriminate and reproduce three types of depth relationships in either drawings or photographs: enclosure, where a larger object is placed directly behind a smaller object;…

The research described here is part of a larger study dealing with the acquisition of language awareness in young children. (RM)

Describes research studies stimulated by the concern for facilitation of logical operations in elementary school and junior high school children and based on the assumption that the level of reasoning used for inquiry and concept acquisition by every individual is substantially below his capacity. (PEB)

The development of abstract mathematical thinking is an essential part of mathematics and the geometry is regarded as a suitable domain to serve this purpose. As different technologies such as computers and graphing calculators are widely being used, curriculum developers on geometry should take these technologies into consideration. Several…

This paper examines children's preferences and understanding of stories and story elements by analyzing an extensive collection of art, writing, and teacher observations of one child, Virginia. The paper traces the progession of Virginia's understanding of character, setting, action/plot, and preference for fairy tale structures as evidenced in…

The factor-referenced kits developed by the Educational Testing Service (ETS) are assessed. With support from the National Science Foundation, the researcher surveyed the total range of research done over the past 65 years on the identification of cognitive abilities, principally through factor analysis. From a corpus of an estimated 2,000 data…

Students come to the classroom with theories that they have actively constructed from their everyday experiences. However, some of these theories are incomplete half-truths. Although such misconceptions interfere with new learning, students are often emotionally and intellectually attached to them. Some common mathematical misconceptions involve:…

This proposed alternative instruction model is based on the teach-practice-apply (TPA) paradigm. This paradigm provides a structure facilitating change, while ensuring the enhancement of instructional effectiveness. Suggestions are provided that secondary teachers can use in their classrooms. The steps inherent in the use of each teaching strategy…

The purpose of this study was to: (1) investigate the relationship between the learning approaches of high school students, their prior knowledge, and their attitudes toward chemistry, and their performance on a misconceptions test; and (2) describe and analyze the differences between the responses of students of different learning approaches on…
