Babaian, Caryn; Kumar, Sudhir – American Biology Teacher, 2020
Evolutionary evidence is important scientific background for appreciating the theory of evolution. We describe a STEAM-based lesson plan that uses paleontological drawings and a modern evolutionary database to explore and understand fossil, morphological, and molecular evidence. Together, with a focus on arthropods and the Cambrian explosion,…

Erduran, Sibel; Ioannidou, Olga; Baird, Jo-Anne – International Journal of Science Education, 2021
The incorporation of epistemic aspects of science in science education continues to be a challenge for researchers and practitioners. The paper presents an empirical study investigating how epistemic framing of scientific methods can be incorporated in science teaching, learning and summative assessment, and what impact such framing has on student…

Muniz, Marc N.; Crickmore, Cassidy; Kirsch, Joshua; Beck, Jordan P. – Chemistry Education Research and Practice, 2018
Chemical processes can be fully explained only by employing quantum mechanical models. These models are abstract and require navigation of a variety of cognitively taxing representations. Published research about how students use quantum mechanical models at the upper-division level is sparse. Through a mixed-methods study involving think-aloud…

Yaman, Fatma – International Journal of Science and Mathematics Education, 2018
This study investigates the effect of the science writing heuristic (SWH) approach on the quality of prospective science teachers' (PSTs) argumentative writing and their understanding of the components of argumentation in the SWH approach and their own learning. Ten SWH approach activities were implemented during the semester. The study was…

Smith, Dorothy V.; Mulhall, Pamela J.; Gunstone, Richard F.; Hart, Christina E. – International Journal of Science Education, 2015
This article presents a case study of four academic scientists. These academics teach in the first year of a Bachelor of Science degree at a large research-focused Australian university that has demanded and supported a greater focus on undergraduate learning. Taken as a whole, the accounts of science that the first-year academics in this case…

Naumescu, Adrienne Kozan; Pasca, Roxana-Diana – Acta Didactica Napocensia, 2011
The influence of heuristical strategies upon the level of two experimental classes is studied in this paper. The didactic experiment took place at secondary school in Cluj-Napoca, in 2008-2009 school year. The study theme "The Unsaturated Hydrocarbons--Alkenes" has been efficiently learned by using the most active methods: laboratory…

Lee, Ji-Yeon – Journal on Excellence in College Teaching, 2004
To develop practical Web-based instruction (WBI) design guidelines for faculty and instructional support staff, the author analyzed three different WBI design cases based on interviews with three experts. On the surface, the WBI design processes that each expert used look more alike than different, entailing similar major steps. The underlying…
