Leuchter, Miriam; Naber, Britta – Journal of Research in Science Teaching, 2019
Attention to core concepts in science and engineering in early education has grown recently, and understanding levers as force amplifiers can be recognized as one of these. Previous studies focused on two-sided levers and do not provide sufficient information about children's knowledge of levers as force amplifiers, nor about their learning and…

Roadrangka, Vantipa; Yeany, Russell H. – Journal of Research in Science Teaching, 1985
Data from 60 observations of 10 teachers and 10 each of their students showed that type/quality of teaching strategy predicted 37 percent of variance in engagement and that the more indirect the teaching strategy, the greater the students' involvement in learning tasks. Implications of these and other findings are discussed. (Author/JN)

Hartford, Fred; Good, Ron – Journal of Research in Science Teaching, 1982
Determined if student questioning skills could be taught within framework of an ongoing chemistry course and if acquisition of these skills depends on high school students' (N=108) level of intellectual development. Results indicate that questioning skills can be acquired by students, regardless of their level of Piagetian intellectual…

Westbrook, Susan L.; Rogers, Laura N. – Journal of Research in Science Teaching, 1994
Students (n=46) were assigned to one of three instructional groups (descriptive, question design, and hypothesis testing) to test the hypothesis that descriptive learning cycles are not sufficient to stimulate students to reason at a formal operational level. Analyses indicated that the hypothesis-testing group exhibited a significant increase on…

Clark, Julia V. – Journal of Research in Science Teaching, 1983
Ascertained influence of an intervention in development of operational seriation/transitivity in kindergarten/first-grade children (N=60) who initially failed to demonstrate ability to do seriation/transitivity problems. Seriation of size was also studied. Results, interpreted in context of Piaget's equilibrium theory, indicated advancement toward…

Wolfinger, Donna M. – Journal of Research in Science Teaching, 1982
Effect of science instruction on young children's (N=64) concept of Piagetian physical causality was investigated. Results indicate, that pre/concrete-operational children can learn and apply a definition of living when that definition is taught through observable characteristics. Additional results and implications for elementary science…

Hall, Donald A.; McCurdy, Donald W. – Journal of Research in Science Teaching, 1990
Compared is an inquiry-oriented Biological Sciences Curriculum Study (BSCS) style laboratory approach with a more directive traditional approach on student outcomes in the cognitive and affective domains of learning. Differences in science achievement, reasoning ability, attitude, and stages of development are discussed. (KR)

Berg, Craig, A.; Phillips, Darrell G. – Journal of Research in Science Teaching, 1994
Using Piagetian tasks designed to assess specific mental structures, researchers investigate the relationship between logical thinking structures and the ability of students to construct and interpret line graphs. Results revealed that a significant correlation exists between the aforementioned variables. Suggests and cautions that only at certain…
