Eyeballs in the Fridge: Sources of early interest in science

This paper examines the experiences reported by scientists and graduate students regarding the experiences that first engaged them in science. The interviews analysed for this paper come from Project Crossover, a mixed‐methods study of the transition from graduate student to PhD scientist in the fields of chemistry and physics. This analysis involved review of 116 interviews collected from graduate students and scientists and focused on the timing, source, and nature of their earliest interest in science. The majority (65%) of participants reported that their interest in science began before middle school. Females were more likely to report that their interest was sparked by school‐related activities, while most males recounted self‐initiated activities. Our findings indicate that current policy efforts (which focus on high school science reform) to increase the numbers of students studying in the science fields, may be misguided.

When is Homework Worth the Time?: Evaluating the Association Between Homework and Achievement in High School Science and Math

Even with the history of debate over the merits of homework, there are significant gaps in the research record regarding its benefit to students. The focus of this study is on the association between time spent on homework and academic performance in science and math by assessing survey and transcript data from two nationally representative samples of high school students collected in 1990 and 2002. Using multiple linear regressions and controlling for students’ background, motivation, and prior achievement, we investigated how much variance in science and math course grades and achievement test scores could be explained by time spent on homework in those classes. The results indicate that there is no consistent significant relationship between time spent on homework and grades, but a consistently positive significant relationship between homework and performance on standardized exams.

What Are Students Doing during Lecture? Evidence from New Technologies to Capture Student Activity.

Engaging students in class is paramount if they are to gain a deep understanding of class content. Student engagement is manifested by attention to the various components of instruction. However, there is little research at the tertiary level focusing on what aspects of instruction are related to changes in student attention during class. To address this gap, we collected multiple streams of data that provide a measure of student attention during instruction. We had students in an organic chemistry course who wear hats with a camera mounted on the brim, to provide a record of student gaze (i.e. looking at the board, notes, and friends). We also had students who use electronic pens that allowed us to record what information students transferred into their notes (pencasts). Based on our initial results, we believe the data provided by the point-of-view cameras and electronic pens hold great promise for using these technologies as viable research tools in educational settings to address various research questions.

A Summer Math and Physics Program for High School Students: Student Performance and Lessons Learned in the Second Year.

For the past two years, the Foundations in Physics and Mathematics (FPM) summer program has been held at Indiana University in order to fulfill two goals: provide additional physics and mathematics instruction at the high school level, and provide physics graduate students with experience and autonomy in designing curricula and teaching courses. In this paper we will detail changes made to the program for its second year and the motivation for these changes, as well as implications for future iterations of the program. We gauge the impact of the changes on student performance using pre-/post-test scores, student evaluations, and anecdotal evidence. These data show that the program has a positive impact on student knowledge and this impact was greater in magnitude in the second year of the program. We attribute this improvement primarily to the inclusion of more inquiry-driven activities. All activities, worksheets, and lesson plans used in the program are available online.1
