Solar Cells, D. Venkataraman
Solar Cells, D. Venkataraman
Science and Engineering Saturday Seminars
Solar cells convert the sun's energy into electrical energy. In this workshop, I will discuss the processes involved in solar cell and various types of solar cells that are being developed as an alternative to silicon solar cells. I will also demonstrate how students can build a solar cell from readily available materials.

Developing Spatial Reasoning Skills In General Chemistry Students, Deborah L. Carlisle
Developing Spatial Reasoning Skills In General Chemistry Students, Deborah L. Carlisle
Doctoral Dissertations
The study of organic chemistry requires the understanding and use of spatial relationships, which can be challenging for many students. Prior research has shown that there is a need to develop students’ spatial reasoning skills. To that end, this study implemented guided activities designed to strengthen students’ spatial skills, with the aim of preparing students for organic chemistry and other future STEM courses. Students, taking the second semester of a two-semester general chemistry course, engaged in these activities. This study followed a quasi experimental design, in which the experimental (n = 209) and the control group (n = 212) were …
