Video and interactive media provide visual exposition and review for students to formulate cognitive representations where learning and reflection take place, especially in science laboratories. More inclusively, open educational resources (OER) with interactive content can facilitate access to media-enhanced learning. This paper reports part of a…

Video analysis helps students to connect physical, mathematical, and graphical models with the phenomena that the models represent and improves student kinematic graph interpretation skills. The wide-spread availability of easy to use software packages like Logger Pro (Vernier), Capstone (PASCO), and Tracker have led to many introductory physics…

While research shows that responsive teaching fosters students' disciplinary learning and equitable opportunities for participation, there is yet much to know about how teachers come to be responsive to their students' experiences in the science classroom. In this work, we set out to examine whether and how engaging teachers as learners in doing…

For the promotion of students' learning in science, teachers must attend to critical classroom situations in which students express their ideas about scientific concepts and methods. The notion of professional vision is used to describe the skill of noticing situations that are relevant for learning and understanding. The present study contributes…

Previous research suggests that everyday expressions are commonly used in students' descriptions of nutrient uptake. This study investigate a classroom context in year 5 with a focus on signs of scientific meaning-making about nutrient uptake with an animation as a resource in two different schools. In one of the schools there was also a teacher…

Engaging preservice teachers in the analysis of videos of teaching has become a widely-used and highly-regarded approach within teacher preparation. This approach has become even more pronounced in the wake of COVID-19. Despite the myriad ways that video can support teacher preparation, uncertainties remain regarding how to design and facilitate…

Recently there is an increasing need for experiments that can be conducted remotely. In this sense, this paper presents three experiments about materials science and an X-ray diffraction (XRD) technique that can be taught and performed entirely remotely. The first experiment is about the calculation of lattice parameters, atomic radii, and…

Going beyond ceremony to meaningfully integrate the lived experiences and narratives of Blacks particularly African Americans in the science curriculum, requires pragmatic research methodologies. K-12 science curriculum development neither considered the needs of African Americans nor were developed with Blacks in mind. Many questions arise…

In this paper, we present simple demonstrations aimed at explaining the fundamental principles of the photoacoustic effect. To display the audible phenomenon that occurs as laser radiation gets absorbed by ethene gas, an optical chopper was used to modulate the power of a continuous-wave laser whose beam was directed into a gas. The absorbed…

Background and Context: To better reflect the computational nature of STEM disciplines and deepen learning of science content computational thinking (CT) should be integrated in science curricula. Teachers have a critical role in supporting effective student learning with CT integrated curricula in classroom settings. Objective: Our team worked…

The purpose of this study was on understanding and interpreting five minoritised pre-service teachers' past educational experiences that impacted their first-time science microteaching experiences in a science teaching methods course. The study is unique because it illuminates and contributes to the literature on the importance of minoritised…

Student-generated videos (SGVs) are gaining popularity and have been increasingly incorporated into undergraduate curricula in many disciplines. Through the creation of their own educational digital videos, students learn course content and transferrable skills. However, the use of SGVs in anatomy and physiology (A&P) is virtually…

Beginning abruptly in the second half of the Spring 2020 semester at Purdue University, we modified our teaching approach in Introductory Soil Science and Forest Soils courses (AGRY 255/270) with a combined annual enrollment of [approximately]370 students to cope with the COVID-19 pandemic. In that semester, we went to entirely virtual lecture,…

Argumentation is vital in the development of scientific knowledge, and students who can argue from evidence and support their claims develop a deeper understanding of science. In this study, the Argument-Driven Inquiry instruction model was implemented in a two-semester sequence of introductory biology laboratories. Student's scientific…

Research has explored how science teachers can create equitable learning environments. In addition, research demonstrates that representations can be powerful tools for supporting disciplinary learning and inviting and leveraging students' diverse ideas and practices. Yet, professional development (PD) about representations has primarily focused…
