Reed, Charlotte R.; Wolfson, Adele J. – Journal of College Science Teaching, 2021
Learning progressions (LPs) present a potential tool to guide students toward deeper understanding of core concepts as they move through a curriculum. In addition to providing a theoretical scheme for education researchers, LPs can provide a powerful framework for instructors and students in organizing curricula. We have developed the outline of a…

Frey, Regina F.; Fisher, Beth A.; Solomon, Erin D.; Leonard, Denise A.; Mutambuki, Jacinta M.; Cohen, Cheryl A.; Luo, Jia; Pondugula, Santhi – Journal of College Science Teaching, 2016
This article describes a visual approach to integrating observational data into self-evaluation and peer review of teaching, practices that can lead to adoption of evidence-based active-learning strategies in STEM. This approach was designed to be implemented for undergraduate courses across disciplines. The presentation of observational data in a…

Harwood, William S. – Journal of College Science Teaching, 2004
There has been renewed discussion of the scientific method, with many voices arguing that it presents a very limited or even wholly incorrect image of the way science is really done. At the same time, the idea of a scientific method is pervasive. This article identifies the scientific method as a simple model for the process of scientific inquiry.…

McCallister, Gary – Journal of College Science Teaching, 2005
The DNA triplet code also functions as a binary code. Because double-ring compounds cannot bind to double-ring compounds in the DNA code, the sequence of bases classified simply as purines or pyrimidines can encode for smaller groups of possible amino acids. This is an intuitive approach to teaching the DNA code. (Contains 6 figures.)
