This study compared students' investigations with an atomic force microscope and viruses in real-time synchronous and asynchronous learning environments. Student interactions with scientists (live videoconference versus email) were examined to see whether communication patterns were different for the different modes of instruction. Students'…

Reviews the literature concerning sociocultural factors, teacher influences and experiences that effect girls attitudes about entering science careers. Discusses a model of these influences on girls. Makes recommendations including increased opportunities and encouragement to foster more favorable attitudes toward science and increase science…

Describes the effects of ability-paired student interactions on achievement as fifth graders (n=83) worked on laboratory activities relating to balance. Results revealed that low ability student achievement is greater, they speak more words, exhibit less distracting behavior, and move blocks on the lever less when they are paired with a partner of…

Investigated were the seating patterns of target students in science classrooms to see whether there was an action zone or T zone present. Questioning level, understanding level of students, and pacing of instruction by teachers are discussed in terms of target students. (KR)

This exploratory case study investigates relationships between use of an inquiry-based instructional style and student scores on standardized multiple-choice tests. The study takes the form of a case study of physical science classes taught by one of the authors over a span of four school years. The first 2 years were taught using traditional…

Describes teacher activities for a unit on birds and the stations for performance-based assessment of student learning. Activities include predicting a birds habitat based on the foot shape, predicting the food of a bird based on its beak, identifying a bird by its song, and identifying bird skins using a field guide. (PR)

Describes what happens when two lead teachers in a statewide reform project try to change science teaching in their schools. Illustrates the importance of patience in reform implementation and the need for sensitive study of early change within school contexts. Includes 24 references. (DDR)

This study investigated the seating patterns of target students in science classrooms to see if there was an action zone or t-zone present. Fifty-six physical science and chemistry classes were observed using the Brophy-Good Teacher-Child Dyadic Observation System. Target students were identified and their interactions were compared to non-target…

Nationally many middle-level schools are changing from a traditional junior high school structure (grades 7-9) to middle schools (grades 6-8). A case study examined the impact of middle school organizational changes that occurred as a large North Carolina school system converted from junior high schools to middle schools on science teachers and…

Observes 16 students from five elementary science classes to examine how students use tools when constructing new knowledge during science instruction, how control of tools is actualized from pedagogical perspectives, how language and tool accessibility intersect, how gender intersects with tool use, and how competition for resources impacts…

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 study investigated the impact of haptic augmentation of a science inquiry program on students' learning about viruses and nanoscale science. The study assessed how the addition of different types of haptic feedback (active touch and kinesthetic feedback) combined with computer visualizations influenced middle and high school students'…

To reduce curricular fragmentation in science education, reform recommendations include using common, unifying themes such as scaling to enhance curricular coherence. This study involved 215 participants from five groups (grades 5, 7, 9, and 12, and doctoral students), who completed written assessments and card sort tasks related to their…

The use of unifying themes that span the various branches of science is recommended to enhance curricular coherence in science instruction. Conceptions of spatial scale are one such unifying theme. This research explored the accuracy of spatial scale conceptions of science phenomena across a spectrum of 215 participants: fifth grade, seventh…

Although there have been numerous scientists-in-the-classroom initiatives in recent years, there is little research that documents whether or not these initiatives make an impact on students. This study examined 27 seventh-grade and 27 tenth-grade students' perceptions of scientists before and after a weeklong educational experience on…
