As a result of the worldwide dissemination of COVID-19, educational institutions across the globe, particularly those that serve students in the field of science, have been mandated to close their doors. Consequently, educators and students have increasingly relied on educational technology to obtain a diverse array of resources. This research…

This study examines the use of an explicit, reflective method for teaching the difference and relationship between scientific theories and laws to ninth-grade students. Students reflected individually and then as a whole class on theories and laws using a Venn diagram, both before and after reading short articles describing features of theories…

Research suggests that connecting the visible (macroscopic) world of chemical phenomena to the invisible (particulate) world of atoms and molecules enhances student understanding in chemistry. This approach aligns with the science standards and is fundamental to the redesigned AP Chemistry curriculum. However, chemistry is usually taught at the…

In spite of being readily available, photographs have played a minor and passive role in science classes. In our study, we present an active way of using photographs in classroom discussions with the use of a classroom response system (CRS) in middle school astronomy classes to teach the concepts of day-night and seasonal change. In this new…

The ability to interpret and reason from Tree of Life diagrams is a key component of twenty-first century science literacy. This article reports on the authors' continued development of a multifaceted research-based curriculum--including an instructional booklet, lectures, laboratories and a field activity--to teach such tree thinking to biology…

Recognizing that undergraduate students can benefit from analysis of 3D protein structure and function, we have developed a multiweek, inquiry-based molecular visualization project for Biochemistry I students. This project uses a virtual model of cyclooxygenase-1 (COX-1) to guide students through multiple levels of protein structure analysis. The…

The ability to interpret and reason from Tree of Life (ToL) diagrams has become a vital component of science literacy in the 21st century. This article reports on the effectiveness of a research-based curriculum, including an instructional booklet, laboratory, and lectures, to teach the fundamentals of such tree thinking in an introductory biology…

We explored whether existing curricula can be adapted to increase students' skills at comprehending and learning from diagrams using an intervention delivered by regular middle-school teachers in intact classrooms. Ninety-two teachers in three states implemented our modified materials over six curricular units from two publishers: "Holt"…

Can novel 3D models help students develop a deeper understanding of core concepts in molecular biology? We adapted 3D molecular models, developed by scientists, for use in high school science classrooms. The models accurately represent the structural and functional properties of complex DNA and Virus molecules, and provide visual and haptic…

Learning the meaningful use of the microscope is an essential requirement in school curricula. Modern science and medicine is hardly conceivable without the inclusion of microscopy. The number of didactic studies in this area, however, is negligible. Real microscopy is rarely used to gain knowledge in higher school years. Could the understanding…

PowerPoint presentations (PPTs) have become routine in medical colleges because of their flexible and varied presentation capabilities. Research indicates that students prefer PPTs over the chalk-and-talk method, and there is a lot of debate over advantages and disadvantages of PPTs. However, there is no clear evidence that PPTs improve student…

Statement of Problem: In this study, in teaching the unit "electricity in our lives" in the 7th grade science and technology class, the effect of using smart boards to the students' retention of the information is examined and compared to the 2005 Science and Technology curriculum. Purpose of the study: The aim of the current study is to…

Understanding key concepts in molecular biology requires reasoning about molecular processes that are not directly observable and, as such, presents a challenge to students and teachers. We ask whether novel interactive physical models and activities can help students understand key processes in viral replication. Our 3D tangible models are…

The ability to represent the world like a scientist is difficult to teach; it is more than simply knowing the representations (e.g., graphs, words, equations and diagrams). For meaningful science learning to take place, consideration needs to be given to explicitly integrating representations into instructional methods, linked to the content, and…

The scientific process is nonlinear, unpredictable, and ongoing. Assessing the nature of science is difficult with methods that rely on Likert-scale or multiple-choice questions. This study evaluated conceptions about the scientific process using student-created visual representations that we term "flowcharts." The methodology,…
