Demonstrated an experiment on the properties of air to 2 groups of Swedish fourth graders (total n=45), using familiar materials in one case and unfamiliar, "scientific," materials in the other. Written explanations by students show that the unfamiliar materials were a barrier to understanding and may have actually obstructed students'…

Investigated whether differences existed between gifted (N=25) and nongifted (N=25) fifth graders and between the sexes and related subgroups with respect to attitudes toward science. Although results indicated that gifted students had more positive attitudes than nongifted students and boys had more positive attitudes than girls, the findings…

The scientific and technological literacy of sixth graders in Israel was assessed though a national evaluation of the elementary science curriculum with over 2,700 students. The definition of scientific and technological literacy for this study is discussed. By the definitions in the study, very few sixth graders had achieved the desired literacy…

A procedure-based observational scoring system and a notebook completed by students were evaluated as science assessments for 41 fifth grade students experienced in hands-on science and 55 fifth grade students inexperienced in hands-on science. Results suggest that notebooks may be a reasonable, although less reliable, surrogate for observed…

In the context of Phase Four of the National Assessment of Educational Progress (NAEP) Science Attribute Study, this report includes a discussion of item attributes, an overview of the item attributes used in the study, some psychometric characteristics of the blocks analyzed, a general description of the rule-space methodology, the results…

A study of students' thinking processes during their engagement in classroom tasks in science and social studies units in upper elementary school classrooms was conducted as part of a series of studies on learning. As a result of previous studies, a theory of the learning process has been developed. A central component of the theory is the…

The purpose of this investigation was to compare the knowledge regarding marine organisms and their feeding relationships of fourth grade residents of one coastal and one inland community in south Texas and to generate grounded theory concerning the participants' construction of such knowledge. Four male and four female students were randomly…

This project manual is written for 4-H member children who are in the fifth grade or older. This project is designed to familiarize members with the scientific history concerning the discovery and application of electric energy through the 1800's. Readers can conduct experiments similar to the ones performed by the scientists and inventors of that…

The Challenger Learning Center of Kentucky is 1 of 34 Challenger Center sites for space science education nationally and the only one in a rural area. Since the center's opening in March 1999, some 5,500 sixth-graders have "flown" space missions that involved using teamwork and math and science skills to solve problems and complete the…

This study explored the sensitivity of a multilevel approach in detecting outcomes of a hands-on science program, exploring whether the instruction of a hands-on unit had any impact on students' performance and whether the estimated magnitude of the impact was different according to the proximity of the assessments to the unit taught. Also studied…

This paper reports on a qualitative study of children's discourse-reasoning about knowledge objects emerging when the classroom becomes a community of discourse. Its purpose was to analyze metacognitive reflections with respect to the steps of the argument. Within science education classes, a part of a wider ecological curriculum was implemented…

Effects of animated graphics presentations on incidental learning and the degree to which various computer practice activities contain intrinsically motivating characteristics were studied with 70 fourth graders learning about Newton's laws of motion. Incidental learning occurred without sacrifice of intentional learning. Students were highly…

Studied the development of writing skills as a way to raise academic achievement for four year-6 ethnic minority students in an English classroom. Identifies strategies that increased achievement and confidence of students and parent participation in their schooling. (SLD)

Reported is a study of sixth-graders' attitudes towards electrical energy. Students in Catawba County, North Carolina schools, which field-tested the Energy for Today and Tomorrow (EFTT) module, completed a 17-item attitude test, the Environmental Opinion Scale. This instrument measured opinions regarding nuclear power, electrical power…

Analyzed the relationship between general coding orientation and specific characteristics associated with the family (social class, race, gender) and the school (pedagogic practice and science achievement) of (n=80) socially differentiated elementary school children. Found that there is a mutual influence of family and school factors on students'…
