A study investigated the relationships among prior topic knowledge, information in elementary science text, and the construction of visual representation of key text ideas. Eight preservice elementary teachers were first interviewed on two topics in science ("how plants get their food" and "air and weather"); then they read…

Many educators in facilitative roles have approached the subject of visual disabilities by constructing activities designed to simulate blindness, using a blindfold or similar device. Participants are subsequently encouraged to perform rudimentary tasks such as eating a meal or moving about with a sighted companion as a guide. Frequently,…

The nature of qualitative understanding and associated learning processes in the context of a computer simulation called the "Envisioning Machine" (EM) are investigated. The questions focused on in this paper include the following: What sorts of knowledge do students' construct? What role does prior knowledge play in the construction of…

In this article, the author compares the arguments of Susan Swartzlander, Diana Pace, and Virginia Lee Stamler (1993) who note the contradiction between the "shockingly unprofessional" practice of asking students to write about their personal traumas in writing courses and the common occurrence of such assignments with Jeffrey Berman…

The Rule Space Model, a cognitive error diagnostic methodology, is discussed, and the philosophy behind it is related to the question of what really determines item response curves. The Rule Space approach integrates Item Response Theory and the algebraic theory of databases. An application of Graph Theory is introduced as a way to acquire a list…

Contemporary researchers often refer to the information processing paradigm to exlain the relative ineffectiveness of contemporary instructional techniques for modifying incorrect scientific concepts that students often bring to a learning situation. As a result of this research, instructional procedures have been developed that maximize the…

Examines the nature of selected traditional cosmological concepts among literate and nonliterate Nigerians. Findings indicate that the respondents, regardless of their status, hold both scientific and traditional notions of the universe. A preference for a scientific world view was evidenced by those who experienced a history/philosophy of science…

Explores how a set of possible student misconceptions about solving a complex problem can be used in computer-based intelligent tutoring systems and in computer-based exercise and test generation. Topics discussed include expert systems, misconception covers, discrimination trees, methods of acquiring the set of misconceptions, and protocol…

Bill Gates and the governors were quite vague about what makes the schools obsolete or what to do about it. What is it, exactly, that schools are not teaching that they need to? Bill Gates also claimed that American kids were at the top in fourth grade, but at the bottom by 12th. The author congratulates Gates for focusing some attention on…

The purpose of this study was to examine pre-service elementary teachers' understanding of the concept of photosynthesis and inheritance, to explore their self-efficacy beliefs in teaching science, and to investigate the relationship between these two issues. Data were gathered through the use of misconception and science teaching efficacy beliefs…

Research shows that one of the most important prerequisites for student success is for teachers to understand and respect individuals from different cultures, and to understand the communities from which they come (Ilmer, Synder, Erbaugh & Kurtz, 1997). Thus, if we want students to succeed, what they bring into the science classroom in terms of…

The focus of the study was to identify and describe environmental preconceptions held by preservice elementary teachers about three issues: greenhouse effect, ozone layer depletion, and acid rain. One hundred and thirteen junior or senior level elementary education majors enrolled in science methods courses at a large Midwestern university…

An innovation-focused Organisation of Economic Cooperation and Development (OECD) study of 13 nations participating in the Third International Mathematics and Science Study (TIMSS) found universal unhappiness with the state of mathematics and science education. There was no link among successful test scores, improvement goals, or satisfaction of…

Richard Rothstein's booklet "What Do We Know About Declining (Or Rising) Student Achievement?" claims that anecdotes about past educational practices are unreliable and difficult to relate to today's schools. Curricula and tests change; so do student populations. There are no solid historical measures, including three well-known…

Recounts the perspectives of several biologists who believe that evolutionary theory is the key to an understanding of biology. Cites examples from textbooks and educational practices which support the theory that many students develop and maintain misconceptions about evolution due to instruction. Contains 53 references.
