Describes a partnership between a fifth-grade teacher and a university methods professor that involved developing an elementary science fair project mentored by university students. Provides opportunities for elementary students to conduct scientific investigations to learn about science, and opportunities for education majors to have firsthand…

Reports on a study of occupational stress among 30 American Indian, Hispanic, and White teachers at a reservation school. Concludes that, regardless of race or sex, major sources of stress were inadequate salary, lack of professional recognition, and time management problems. Contains 22 references. (SV)

The article discusses the classic problem: "Given an equilateral triangle and a point P inside the triangle, what is the sum of the distances from P to the three sides?" The problem is used to illustrate the generative nature of problem-posing using the heuristic "What happens if...?" (PK)

Review of charts for 141 children who had undergone both a screening interview by an emergency department physician and an investigative interview for child sexual abuse evaluation found that perpetrator identification obtained during emergency department screening interviews usually agreed with information obtained at the subsequent investigative…

Gives an example of an open exploration using trigonometric relationships in which the law of cosines can be deduced from the law of sines. Discusses the characteristics and value of the exploration process. (MDH)

An inquiry-based high school science class was developed to create a learning environment that would facilitate the development of scientific talent in students in a comprehensive high school. The class was designed to motivate students to pursue a sophisticated, substantial, independent scientific investigation over 2-3 years. (JDD)

Presents an activity in which students in grades 5-8 learn about snail reproduction by observing and charting the activities of land snails, freshwater snails, and slugs. Instructions to implement and extend the activity are provided. (MDH)

Describes the EQUALS Family Science Program, a national program designed to promote equity in mathematics, science, and technology, in which the goal is to make children and parents more scientifically literate by doing science investigations together. Presents activities that teachers can use to promote scientific literacy and cultural diversity.…

This Italian contribution to the STTIS (science teacher training in an information society) investigations of transformations of curriculum innovations looks at the implementation of the use of real-time experiments and images (RTEI), in which computer data acquisition and display is built in to aspects of science teaching. Certain critical…

The purpose of this article is to report findings from an ethnographic study that focused on the co-development of science literacy and academic identity formulation within a third-grade classroom. Our theoretical framework draws from sociocultural theory and studies of scientific literacy. Through analysis of classroom discourse, we identified…

In this article, the author discusses the CHANCE (Connecting Humans and Nature in the Costa Rican Environment) program, a coordinated effort between The Pennsylvania State University (PSU) and the Pennsylvania Department of Education that trains 9th- through 12th-grade teachers to be more like scientists and develop a unique, pedagogical tool for…

The current research investigates infants' perception of a novel object from a category that is familiar to young infants: key rings. We ask whether experiences obtained outside the lab would allow young infants to parse the visible portions of a partly occluded key ring display into one single unit, presumably as a result of having categorized it…

Through examination of 613 students' narratives about self-selected important decisions, I investigated the student and situation characteristics related to provocation and use of self authored ways of knowing. The findings gesture toward both particular skills students may need to develop in order to self-author, as well as suggest that movement…

How much can late schooling investments close racial and ethnic skill gaps? We investigate this question by exploiting the large differences in completed schooling that arise among teenagers with birthdays near school-entry cutoff dates. We estimate that an additional year of high school raises the Armed Forces Qualifying Test (AFQT) scores of…

We describe a polymerase chain reaction (PCR) protocol suitable for use in secondary schools and colleges. This PCR protocol can be used to investigate genetic variation between plants. The protocol makes use of primers which are complementary to sequences of nucleotides that are highly conserved across different plant genera. The regions of…
