Building on the scientific and investigative knowledge that students acquire over the years, this program delves deeper into the theory of "science as inquiry". This program helps students recognize the intricate relationship between explanation and evidence through engaging examples. Students trace the path of scientific inquiry--guided by…

This bulletin comprises the results of personal investigations supplemented by official reports covering the entire work of medical inspection as developed in Great Britain, including: (1) History of the development of medical inspection in England, Wales, and Scotland; (2) Administration by the chief medical staff, (3) Medical examination--the…

Algorithmic and investigative approaches to mathematics are compared and discussed. Their mutually contradictory spirit is explored. Examples of the application of each method to a mathematics problem are presented. (CW)

Presents 5 activities for the K-1, 2-3, 4-5, 6-8 grade levels and for in the home in which students explore the concept of combinations. Each activity includes a lesson plan to investigate a combinatorics problem appropriate for that grade level. Provides reproducible worksheets. (MDH)

Presents two seasonally related investigations involving arithmetic series to develop critical thinking: (1) the number of candles needed for the eight nights of Hanukkah, and (2) the number of presents given during "The Twelve Days of Christmas." Students also calculated the amount of money needed to buy all the presents. (MDH)

Describes an inexpensive spectrum projector that makes high-dispersion, high-efficiency diffraction gratings using a holographic process. Discusses classroom applications such as transmission spectra, absorption spectra, reflection characteristics of materials, color mixing, florescence and phosphorescence, and break up spectral colors. (MDH)

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)

Discusses the inherent flaws in considering and using the epistemology of the natural sciences as equivalent to a pedagogic basis for teaching and learning in the natural sciences. Discusses the difference between practicing science and learning to practice science. Concludes with the presentation of three new motives for the use of laboratory…

Seven articles highlight evaluations that are especially investigative in nature to examine how common elements in these studies can be used to improve evaluation and practice. The evaluator is seen as detective, ethnographer and management consultant, national program monitor and analyst, and international development specialist. (SLD)

An important goal of mathematics education reform is to support teacher learning. Toward this end, researchers and teacher educators have investigated ways in which teachers learn about mathematical content, pedagogical strategies, and student thinking as they implement reform. This study extends such work by examining how one elementary school…

In an attempt to generate student enthusiasm on the subject of genetics, the author developed a Punnett square activity centered on the genetics of corn snakes to teach students about Mendelism and genetic diversity. As they began the activity, however, some unexpected twists occurred that allowed for investigation into corn snake anatomy and…

Background: In this study, psychosocial functioning of different groups of young children with learning problems was investigated using a diverse set of psychosocial variables (including behaviour problems, academic motivation, social preference, and self-concept). Methods: For this purpose, children with low academic achievement, with a specific…

The author examined age, gender, and ethnic differences in the self-perceptions of 112 low-income children who were assessed with the Pictorial Scale of Perceived Competence and Social Acceptance (PSPCSA) at Head Start and kindergarten. Children's self-ratings of competence were overly optimistic across the 4 subscales of the PSPCSA during the 2…

The purpose of this investigation was to apply a validated curriculum evaluation instrument, the "Science Curriculum Implementation Questionnaire" (SCIQ), in an educational context in which a science curriculum review had recently been completed and, by so doing, ascertain the accuracy and potential value of the instrument as a…

The amygdala appears necessary for enhanced long-term memory associated with emotionally arousing events. Recent brain imaging investigations support this view and indicate a sex-related hemispheric lateralization exists in the amygdala relationship to memory for emotional material. This study confirms and further explores this finding. Healthy…
