Bram Bruininks; Ludo B. F. Juurlink – Journal of Chemical Education, 2022
We present the design of a periscope-type VIS spectrometer for educational purposes that combines strong features from various earlier designs and adds new ones. Three 3D-printed pieces that hold a small thin mirror sheet, a 1/8th wedge of a DVD, and two razor blades are easily assembled and facilitate insight into its construction. A new feature…

Pinger, Cody W.; Geiger, Morgan K.; Spence, Dana M. – Journal of Chemical Education, 2020
Wide accessibility and a broad range of applications have made 3D-printers a commonplace tool in the science community. From tier-one research institutions to community public libraries and high schools, 3D-printers are being used to enrich STEM education through a variety of learning techniques and experiences. Reports of 3D-printed models for…

Lu, Chow-Chin; Chen, Yueh-Yun; Chen, Chen-Wei – International Journal of Science and Mathematics Education, 2011
The central focus of this study was the development, use and evaluation of CD-ROM picture books in elementary school science teaching. Three CD-ROM picture books based on the Campus Insects unit from the new elementary school science curriculum in Taiwan were developed. A quasi-experimental method was used to compare the use of the CD-ROMs and…

Cantrell, Pamela; Sudweeks, Richard – Journal of Computers in Mathematics and Science Teaching, 2009
This project investigated the effects of technology task autonomy, teacher gender, and student gender on student achievement scores for students disaggregated by IEP and SES in middle school science classrooms. Participants were from the treatment group in a larger quasi-experimental design project that investigated the effects of integrated…
