An introductory physics course may be run like a video game, where students have an almost unlimited number of attempts to demonstrate their competencies through a sequence of zero-penalty assessments until the end of a semester. Each checkpoint is conducted as a 10-minute, one-on-one oral interview with the instructor, and students are not…

We present a new learning unit, which introduces 12 year-olds to the subatomic structure of matter. The learning unit was iteratively developed as a design-based research project using the technique of probing acceptance. We give a brief overview of the unit's final version, discuss its key ideas and main concepts, and conclude by highlighting the…

Despite advances to move anatomy education away from its didactic history, there is a continued need for students to contextualize their studies to make learning more meaningful. This article investigates authentic learning in the context of an inquiry-based approach to learning human gross anatomy. Utilizing a case-study design with three groups…

This study explores if and how teachers combine practices of science and of preschool (children 1-5 years old) into preschool science practice. Views of knowing may differ between science practices, traditionally associated with masculinity and rationality, and preschool practices, traditionally associated with femininity and caring. Recognising…

Drawing appropriate diagrams is a useful problem solving heuristic that can transform a problem into a representation that is easier to exploit for solving it. One major focus while helping introductory physics students learn effective problem solving is to help them understand that drawing diagrams can facilitate problem solution. We conducted an…

Despite the number of university students who take courses in multiple science disciplines, little is known about how they connect concepts between disciplines. Energy is a concept that underlies all scientific phenomena and, as such, provides an appropriate context in which to investigate student connections and misconnections across disciplines.…

Recently, theorists have raised concerns that pedagogical content knowledge (PCK) has become "a stale metaphor" that disregards diversity and equity, offers little to help teachers address students' misconceptions, and portrays knowledge as "in the head" versus in practice. We refute these notions using grounded theory to…

Children often learn information in a context that is vastly different to the one in which they are asked to recall or use that information. Despite this, little is known about the effect of context change on children's recall of educational information. Here, 197 5- and 6-year-olds were taught the same interactive lesson in their classroom or on…

While elementary teachers do not typically cover the structure and function of DNA, their students can easily understand that organisms have observable traits, that each individual has a unique combination of traits, and that the "recipe" for traits is passed from parent to offspring. The Genetic Science Learning Center has developed and…

Much of the literature on science teaching suggests that elementary teachers lack relevant prior experiences with science. This study begins to reframe the deficit approach to research in science teaching by privileging the experiences elementary teachers have had with science--both in and out of schools--throughout their lives. Our work uses…

Background: Though active-learning instruction has the potential to positively impact the preparation and diversity of STEM graduates, not all instructors are able to achieve this potential. One important factor is the teacher knowledge that instructors possess, including their pedagogical knowledge. Pedagogical knowledge is the knowledge about…

Misconceptions are the "the old, the bad, and the ugly" prior knowledge, ideas or conceptions that the learners have that hinder their further learning in science. Several types of misconceptions that undergraduate students hold about reaction coordinate diagrams (from here on we use the term "reaction coordinate diagrams" and…

We investigated whether it is possible for 12-year-old students to develop a qualitative conceptualization of energy and four associate features (forms of energy, transfer processes, conservation, and degradation) as a framework for constructing interpretive accounts for the operation of physical phenomena (specifically, for changes taking place…

The teaching lab is an important component of training and developing undergraduate chemistry students. The lab provides a complex teaching environment where faculty address a number of student-centered goals, including the development of technical proficiency, demonstrations of theoretical concepts, promotion of teamwork, and modeling of data…

This study is part of a dissertation which aims to explore and understand the role of play in the teaching-learning process at elementary level in a public school at Pernambuco, Brazil. We opted for a qualitative approach, using the interactive methodology, interviews by the technique of hermeneutic-dialectical circle, observations of science…
