While dissent is recognized as a necessary component of scientific knowledge production, in school settings, it is a double-edged sword that can disrupt and undermine social cohesion just as it can promote thinking and creativity. This pilot study explores patterns of dissent in a science education context. It uses a mixed-methods approach to…

Increasing the number of students choosing a STEM (science, technology, engineering, and mathematics) career is a national educational priority. One way thought to increase interest in STEM is with advanced STEM courses in high school, especially Advanced Placement (AP) courses. Using data from 15,847 college undergraduates, we investigated the…

Both in physics education and in science education more generally concerns exist that formal K-12 education structures limit and, in some cases, diminish students' interest and agency in these fields. Many stakeholders have turned to informal learning experiences as a means to inspire young people to pursue continual learning in these fields in…

It is well known that women are underrepresented in science. technology engineering and mathematics (STEM) and that their interest declines more steeply over the schooling years. As such, this study uses a STEM identity theoretical framework to examine the effects of early STEM experiences, focusing particularly on experiences that may be more…

Participants' engagement in massive online open courses (MOOCs) is highly irregular and self-directed. It is well known in the field of television media that substantial parts of the audience tend to drop out at major episodic, or seasonal, closures, which makes creating cliff-hangers a crucial strategy to retain viewers (Bakker, 1993; Cazani,…

Computer gameplay and social media are the two most common forms of entertainment in the digital age. Many scholars share the assumption that leisure-time digital consumption is associated with CS affinity, but there is a dearth of research evidence for this relationship. Female students generally spend less time on gaming and more time on social…

In this paper, we examine the relationship between participants' childhood science, technology, engineering, and mathematics (STEM) related experiences, their STEM identity (i.e., seeing oneself as a STEM person), and their college career intentions. Whereas some evidence supports the importance of childhood (i.e., K-4) informal STEM education…

Computer science (CS) has been identified as one of the fastest-growing professions, with demand for CS professionals far outpacing the supply of CS graduates. The necessity for a trained CS workforce has compelled industry and academia to evaluate strategies for broadening participation in CS. The current literature in CS education emphasizes the…

In this study the authors set out to better understand the relationship between teacher knowledge of science and student learning. The authors administered identical multiple-choice assessment items both to teachers of middle school physical science and to their students throughout the school year. The authors found that teachers who have strong…

We expand on prior qualitative research about mathematics identity development using data from a large national US survey of 10,437 students in 336 college calculus classes. Multinomial logistic regression models find that a stronger mathematics identity predicts higher student interest in pursuing certain STEM careers when compared with non-STEM…

There has been a growing need felt by practitioners, researchers, and evaluators to obtain a common measure of science engagement that can be used in different out-of-school time (OST) science learning settings. We report on the development and validation of a novel 10-item self-report instrument designed to measure, communicate, and ultimately…

This study examines the relationship between students' pre-college experience with computers and their later success in introductory computer science classes in college. Data were drawn from a nationally representative sample of 10,197 students enrolled in computer science at 118 colleges and universities in the United States. We found that…

Massive open online course (MOOC) studies have shown that precourse skills (such as precomputational thinking) and course engagement measures (such as making multiple submission attempts with assignments when the initial submission is incorrect) predict students' grade performance, yet little is known about whether these factors predict students'…

Background and Context: The relationship between novices' first programming language and their future achievement has drawn increasing interest owing to recent efforts to expand K-12 computing education. This article contributes to this topic by analyzing data from a retrospective study of more than 10,000 undergraduates enrolled in introductory…

This national study of 1858 teachers participating in professional development(PD) summer programs in the United States encompasses a wide range of science subjects and grades. It was conducted to identify program features associated with increases in two types of teacher knowledge that are goals for most professional development programs: teacher…
