Representation use is a critical skill for learning, problem solving, and communicating in science, especially in physics where multiple representations often scaffold the understanding of a phenomenon. University Modeling Instruction, which is an active-learning, research-based introductory physics curriculum centered on students' use of…

We describe a study on the conceptual difficulties faced by college students in understanding hydrodynamics of ideal fluids. This study was based on responses obtained in hundreds of written exams complemented with several oral interviews, which were held with first-year engineering and science university students. Their responses allowed us to…

With growing interest in promoting skills related to the scientific process, we studied performance in solving ill-defined problems demonstrated by graduating biochemistry majors at a public, minority-serving university. As adoption of techniques for facilitating the attainment of higher-order learning objectives broadens, so too does the need to…

The article addresses the problématique of where mathematization is taught in the educational system, and who teaches it. Mathematization is usually not a part of mathematics programs at the upper secondary level, but we argue that physics teaching has something to offer in this respect, if it focuses on solving so-called unformalized problems,…

Capillary electrophoresis is an important analytical separation method used to study a wide variety of samples, including those of biological origin. Capillary electrophoresis may be covered in the classroom, especially in advanced analytical courses, and while many students are exposed to gel electrophoresis in biology or biochemistry…

Computational thinking (CT) parallels the core practices of science, technology, engineering, and mathematics (STEM) education and is believed to effectively support students' learning of science and math concepts. However, despite the synergies between CT and STEM education, integrating the two to support synergistic learning remains an important…

Studies have investigated various aspects of the use of questions in science lessons, but there is still a lack of research that demonstrates how, during peer reflection, teachers learn through identifying and overcoming obstacles to their own questioning in their professional development process. The present study is aimed at analyzing the types…

Districts are scrambling to address climate change performance expectations in the "Next Generation Science Standards" (NGSS). On the flipside, such questions offer vital opportunities to ignite change and give students agency regarding climate literacy and resiliency in the high school classroom. A cohort of science teachers from Denver…

Severe flooding was prevalent within the authors' region at the beginning of the school year. Many homes and fields were affected by the amount of rain that fell within a short period of time over multiple days. Their students were concerned about the impact this natural phenomena was having on their local community. Natural phenomena can provide…

The present study investigates how the different modes of game-design triggers learning outcomes, focusing on peer learning and intergroup competition. A problem-solving science game was developed to help secondary students to learn about the motion of objects. Participants (N = 110) from an urban middle school were randomly assigned to four…

There have been multiple national calls for curricular reform in science, technology, engineering, and mathematics (STEM), including a need to instill democratic skills in students. Democratic skill building can be embedded in STEM classrooms through intentional "deliberative pedagogies" that include communication, collaboration, and…

As science teachers, we often show animations and videos in class but there is the potential for students to create their own animations to represent science concepts and thus make their conceptions visible for critique and refinement. This encourages students to be active in their own learning, creating animations rather than just viewing them.…

We sought to test a hypothesis that systemic blind spots in active learning are a barrier both for instructors--who cannot see what every student is actually thinking on each concept in each class--and for students--who often cannot tell precisely whether their thinking is right or wrong, let alone exactly how to fix it. We tested a strategy for…

This paper investigates the efficacy of an open-inquiry approach to achieve a long term stability of physics instruction. This study represents the natural continuation of a research project started four years ago when a sample of thirty engineering undergraduates, having already attended traditional university physics instruction, were involved…

In this study, we explore the issues and challenges involved in supporting students' learning to discern relevant and critical aspects of determining oxidation states of atoms in complex molecules. We present a detailed case of an interaction between three students and a tutor during a problem-solving class, using the analytical tool of practical…
