Reports a study (n=41) of the effectiveness of in-depth, conceptually integrated instruction delivered via a videodisc program in eliminating children's alternative frameworks in science. This curriculum, which did not directly address alternative frameworks during instruction, changed 92% of the alternative frameworks held by students to…

Although increased attention to testing has resulted in improved guidelines for measuring skills and interpreting test results, educators are confused about certain testing problems and appropriate ameliorative strategies. Changing from multiple-choice formats to authentic performances will not reform education. Highly valuable outcomes such as…

Describes an interview-a-scientist assignment for preservice elementary teachers. Preservice teachers realized that scientists frequently repeat experimental work, that science is not neat and tidy, and that science requires patience and perseverance. (PR)

Students experience the distinction between observable fact and scientific theory by taking a critical look at how spaghetti can be sucked up into the mouth. A demonstration shows that air is needed to suck up the spaghetti but that the scientific explanation is not as simple. (MDH)

Three teaching experiments are reported which study aspects of a diagnostic teaching methodology. An experiment in the field of directional quantities showed a positive relationship between the intensity of discussion and amount of learning; one on fractions and another on geometric reflections showed good two-month retention under the…

Discusses the results of a four-year study of the conceptions of energy held by science teachers in training. Concludes that the group held a number of different alternative conceptual frameworks. Contains 20 references. (DDR)

Many South Chicago schools are successfully using older technologies, including photomechanical language-lab consoles, revamped and networked PCs, and "ancient" software packages rivaling today's expensive, repackaged products. Re-use is cost-effective. Schools should differentiate among computers' capabilities. Despite big industry's…

Despite six decades of leading researchers' research findings upholding progressive, whole-language reading approaches, consensus is lacking. Pundits tend to discredit educational research. News media promulgate tougher standards while overlooking progressive classroom successes. Parents may fear children's exploration of a wide variety of books…

Provides a detailed account of the significant components of Sister M. Gertrude Hennessey's instruction for conceptual change learning in an elementary science classroom. Discusses the implications of this case study for the practices of other teachers. Contains 40 references. (Author/WRM)

Examines two myths or misperceptions associated with premedical education, that of the "premedical syndrome" (over-achieving, competitive, cynical, and narrowly focused students), and the "cutthroat medical student" (competitive to the point of undermining others). The origins of the myths, the purposes they may serve, why they…

Investigates the conceptual-change process in grade 10 students during a computer-supported physics unit. Finds that many students vacillated between alternative and scientific conceptions from one context to another during instruction, and those few students who did exhibit context-independent and stable conceptual change appeared able to accept…

The current emphasis on accountability, standards, and assessment is missing one important dimension--connection to a sense of values and beliefs. In California, standards are stifling creativity and flexibility; standard-setting is too politicized; test scores are eclipsing democratic values; and cash rewards won't necessarily improve student…

Examines changes in the science content representations of two prospective elementary teachers during their first year in an experimental teacher preparation program. Finds that opportunities to engage in cycles of instruction guided by structured considerations for content representation contributed to improvements in the teachers' science…

Discusses ways in which a teacher can mislead students by adopting the wrong strategy when answering an unexpected student question. Presents a scheme for addressing unexpected questions and illustrates it with examples. (Author/WRM)

Students' conceptions about "microbes" tend to condition their understanding of biotechnology. Explores connections between the status given to diseases, a hygiene-oriented culture, layman's versus school knowledge, personal experience, socio-cultural mediation, linguistic confusions, and students' conceptions. (Contains 21 references.)…
