Engaging in interactions with peers is important for student learning. Many studies have quantified patterns of student interactions in in-person physics courses using social network analysis, finding different network structures between instructional contexts (lecture and laboratory) and styles (active and traditional). Such studies also find…

Time is experienced as passing more quickly the more changes happen in a situation. The present research tested the idea that time perception depends on the level of construal of the situation. Building on previous research showing that concrete rather than abstract mental construal causes people to perceive more variations in a given situation,…

The Index of Learning Styles (ILS) generates reliable data. Its ability to characterize learning preference has been validated. However, the ILS has had very limited application in biology education. In 2009, students in an introductory biology laboratory completed the ILS. Overall academic performance (2009) was negatively associated with…

This paper studies the determinants of college major choice using a unique "information" experiment embedded in a survey. We first ask respondents their "self" beliefs--beliefs about their own expected earnings and other major-specific outcomes conditional on various majors, their "population" beliefs--beliefs about…

Introduction: This study investigated the effect of cognitive styles on users' information-seeking task performance using a knowledge domain information visualization system called CiteSpace. Method: Sixteen graduate students participated in a user experiment. Each completed an extended cognitive style analysis wholistic-analytic test (the…

This experiment allows students to use [to the first power]H NMR to directly compare the relative initial rates of substitution of the benzylic and non-benzylic [alpha] hydrogens of [beta]-tetralone and correlate their findings with the predictions made by resonance theory. The experiment demonstrates that the benzylic hydrogens undergo [alpha]…

The purpose of this study was to investigate (a) what effect the use of interactive computer-based simulations (ICBSs), the use of laboratory inquiry-based experiments (LIBEs), and the use of combinations of an ICBS and a LIBE, in a conceptually oriented physics course, have on science teachers' beliefs about and attitudes toward the use of these…
