An Idaho education dean recounts a moving encounter with a fatherless first-grader while visiting his grandson in Eugene, Oregon. Envisioning a deadbeat dad and a burned-out mother, he pondered the statistical odds of this child graduating from college. However, the girl's warm welcome from her teacher helped revise his hopes about the little…

Tests on diffusion and osmosis given to (n=116) secondary biology students, (n=123) nonbiology majors, and (n=117) biology majors found that, even after instruction, students continue to have misconceptions about these ideas. Appendix includes diffusion and osmosis test. (MKR)

Investigation of (n=101) 17- to 18-year-old students' responses to a task relating to Boyle's Law for gases found that 34% to 38% of students did not understand the concepts of volume and mass, respectively, of a gas under the given circumstances. (Author/MKR)

Presents a guided discovery activity that uses fruit flies and can be implemented in introductory biology and nature of science classes to flesh out abstract lectures about life cycles, insect morphology, patterns and causes of animal behavior, and the nature of science. Discusses strengths and drawbacks and results of student evaluations of the…

Explores some theoretical issues raised in Hatcher and Troyna's critical discussion (in this issue of "Journal of Education Policy") of author's work on educational policy. Many of their criticisms are misplaced and rest upon flaws and limitations in their own theoretical work. Their discussion employs a set of unhelpful conceptual…

Contrary to misinformation circulating in the United States, the United States has more engineers absolutely and relatively than does Japan; and U.S. engineers have higher relative income and status than their Japanese counterparts. Compares U.S. and Japanese enrollments in engineering education, curriculum content, engineers' earnings relative to…

Past and current research on the effects of foods ingested and food allergies on hyperactivity and other behavior problems are examined in this article. It is argued that evidence supporting a link between diet and behavior is lacking. Methods for correcting widespread public misconceptions on this subject are also discussed. (Author/PB)

An algebra test administered to (n=18) first-year college students found a disregard for negative numbers, ineffective use of counterexamples, misapplication of rules, and a lack of a good grasp of relevant mathematical terminology. (12 references) (MKR)

Presents correct solutions to an osmosis problem of two high school science students who relied on inaccurate and inappropriate conceptual knowledge. Identifies characteristics of the problem solvers, salient properties of the problem that could contribute to the problem misrepresentation, and spurious correct answers. (27 references) (Author/MKR)

Explores the effects of the square-cube law that predicts the physical consequences of increasing or decreasing an object's size. Uses examples to discuss the economy of scales, common misconceptions, and applications of scaling laws. (JRH)

Advertisers spend billions to market so-called educational products, services, and viewpoints to vulnerable young consumers. Budget constraints are forcing educators to accept ads and promotional materials. Several education and consumer-interest groups are developing guidelines for using commercial materials in schools. Consumers Union developed…

Educators can encourage students to question popular misconceptions about population growth. Identifies and counters 16 population myths based on unverifiable or imaginary relationships. Discusses interventions that have been shown to rapidly bring about reductions in desired family size and actual fertility. (LZ)

Describes the Saskatchewan (Canada) School Improvement Program and illustrates the type of data available from annual evaluation reports. Based on some incongruities identified among specified goals, improvement strategies, and reported success, the paper makes a case for specifying, from the outset, the assessment strategies and success…

Describes a method for capturing a real object and its real image on film. Explains many photography terms related to the experiment. (MVL)

Kinesthetic apparatus make physics learning experiences stimulating, memorable, and influential in helping students relate natural phenomena to the laws of physics. Describes a number of experiments and demonstrations that are possible with kinesthetic apparatus, which help eradicate some traditional student misconceptions and provide students…
