Three modules on chemical equilibrium, developed as resource materials for a content-methodology course in chemistry for intending teachers and also for general chemistry courses at the senior secondary and tertiary levels, are described. The use of these modules in a methodology course showed a significant development of competence in the…

Three groups of sixth, eighth, and tenth graders took pre- and posttests on a Piagetian problem and a problem that evoked a misconception. Two intervention groups engaged in group transactions intended to create inter- and intrapersonal conflicts or took a multiple-choice test. Results indicated that treatment groups progressed on the Piagetian…

The education crisis is like TV violence; the worse it gets, the more inert we become. Truth is that Americans do not really care about education. The young are adept at "reading" adult hypocrisy. Commercialism rules. There is nothing in Homer, Virginia Woolf, Shakespeare, or teaching that will bring youngsters big bucks. Freedom and…

Male undergraduates (n=165) at Kansas State University (Manhattan) were more likely than female undergraduates (n=187) to misperceive behavior of a videotaped professor interacting with a cross-sex student. Results suggest that men view interpersonal interactions in more sexual terms than do women, a finding with implications for study of sexual…

Whether software-based mediated instruction reduces the incidence of misconceptions and errors by children learning the LOGO computer language was studied with 24 fourth and 46 second graders. Mediated instruction reduced errors and misconceptions compared to those detected in prior studies. The roles of working memory and true misunderstandings…

National testing will not improve teacher's genius, students' prospects in life, or learning opportunities in school's immediate surroundings. Too much emphasis will be placed on comparisons among districts, counties, and states. Money will be pumped into raising scores, not decreasing class size or giving teachers more time to work with children.…

Provided is a perspective on the teaching of a unit on the Earth in space. The themes to be found within the unit, approaches and resources that can be used for teaching and learning the subject, and some of the typical ideas that children hold about astronomical subjects are provided. (KR)

Discussed is how modern physics is usually approached via the photoelectric effect and how this can lead to a physically wrong picture of light. The importance of using the quantum theory developed after 1920 to explain the properties of light is discussed. (KR)

Discussed are the recognition and the relevance, in terms of teacher/student awareness and subsequent effective teacher treatment techniques, of cognitive disequilibrium as experienced by the student, when such disequilibrium is provoked by mathematical contradictions and/or counterexamples, within the classroom paradigm of constructivism. (JJK)

Discussed are the results of a test administered to nonmajor biology students on the topic of natural selection. The description of student conceptions, effects of instruction, and the effects of a belief in evolution are included. (KR)

Four college educators critically examine an interaction in an introductory college physics classroom (HE 532 013). They explore the role of prior knowledge and new learning in the classroom discussion, misconceptions, the nature and content of the discussion, classroom techniques, use of language, and the process of concept formation. (MSE)

A questionnaire administered to 288 seventh- through tenth-grade students in 3 rural Oregon school districts revealed students' knowledge concerning the transmission and prevention of AIDS, student attitudes toward AIDS patients, and source of student knowledge; showed improvement over a previous survey of middle school students; and confirms the…

Presents a case study of a special education teacher candidate with a learning disability in mathematics. Issues discussed include the nature of learning disabilities in adults; possibility of workable interventions at the adult level; implications of these problems in teacher candidates; and implications for teacher education programs. (27…

Sketches a theory for designing teaching based on mathematical activity, situations, tasks, and interventions, exposing and resolving cognitive conflicts, changes of structure and context, feedback, reflection and review. Reviews the main psychological principles underlying this theory, then considers some examples of teaching designs in light of…

Considers topics about cell function often misunderstood, misrepresented, or omitted from biology textbooks: enzyme catalyzed reactions; RNA as a catalyst; protein levels in cells; amino acids; organic acids; glucose and fructose; gluconeogenesis; fatty acids and ketone bodies; diffusion; and transport across membranes. (Contains 25 references.)…
