Investigations of a Complex, Realistic Task: Intentional, Unsystematic, and Exhaustive Experimenters
McElhaney, Kevin W.; Linn, Marcia C. – Journal of Research in Science Teaching, 2011
This study examines how students' experimentation with a virtual environment contributes to their understanding of a complex, realistic inquiry problem. We designed a week-long, technology-enhanced inquiry unit on car collisions. The unit uses new technologies to log students' experimentation choices. Physics students (n = 148) in six diverse high…

Linn, Marcia C. – 1979
This document discusses the relation between adolescents' expertise (their informational background, which can be accurate or inaccurate, about a particular task or subject) and their formal operational reasoning, and reports the results of three studies of the effects of children's expertise on reasoning. In Study I, adolescents from a rural…

Linn, Marcia C.; Eylon, Bat-Sheva – Journal of Science Education and Technology, 2000
Contrasts spontaneous and reflective knowledge integration instruction delivered using a computer learning environment to enhance understanding of displaced volume. Distinguishes the impact of instruction on students who believed scientific phenomena are governed by principles (cohesive beliefs) versus students who believed that science is a…

Linn, Marcia C.; Levine, David I. – 1976
A developmental investigation of the ability to control variables was conducted. One or two logically similar physics problems were individually administered to 120 subjects age 12 to 14. The problems involved either familiar or unfamiliar variables. Each problem was presented in three different informational formats. Success on the problems in…
