Modeling Protein Structure & Function: Pencil Transferase

The interrelationship of structure and function is a key theme of biology. One important example of this relationship involves how the three-dimensional shapes of proteins are related to the roles they play at the cellular level. The treatment of protein structure in many introductory textbooks, however, is cursory and focuses on the relationships among primary, secondary, tertiary, and quaternary structure without a clear link to how these levels of organization contribute to functional aspects of the protein.

The Emerging Role of Science Teachers in Fostering Stem Career Awareness

Understanding how high school students become aware of STEM career options, how educators can help students translate awareness into pursuit of STEM careers, and how to provide students with the support and skills they need to succeed, are crucial elements in ensuring the future of our STEM workforce. One important factor is the role that high school science teachers can play in fostering STEM career interest and awareness. As part of our study, we conducted interviews and focus groups with over 70 high school science teachers and other science and career education experts.

Scalable Game Design: A Strategy to Bring Systemic Computer Science Education to Schools through Game Design and Simulation Creation

An educated citizenry that participates in and contributes to science technology engineering and mathematics innovation in the 21st century will require broad literacy and skills in computer science (CS). School systems will need to give increased attention to opportunities for students to engage in computational thinking and ways to promote a deeper understanding of how technologies and software are used as design tools. However, K-12 students in the United States are facing a broken pipeline for CS education.

To Customize or Not to Customize? Exploring Science Teacher Customization in an Online Lesson Portal

New technologies are increasingly giving science teachers the ability to access and customize science lessons. However, there is substantial debate in the literature about whether and under what conditions teacher customization benefit student learning. In this study, we examined teacher customization of inquiry-based science lessons from an online lesson portal. We found that students who completed teacher-customized lessons had greater improvements in science content understanding than students who completed non-customized lessons.
