Science

Rapid technological advances are dominating the evolution of world’s economy and increasingly influencing our daily lives. Even as such advances have greatly improved human living condition, a majority of people either lack the understanding of technology or frequently ignore it. While post-secondary science, technology, engineering, and math (STEM) education seeks to remedy this disconnect, its reach is limited because formal education ends for many students at the secondary level.

The persistent lack of diversity in STEM fields remains a serious challenge for U.S. global competitiveness. STEM jobs are growing 29% faster than any other U.S. sector. Yet, today, white men hold roughly 75% of all scientists and engineering jobs, despite making up only 26% of the total workforce. The cause of this diversity gap can be traced to our educational system, where girls and most children-of-color do not receive equitable public education due to high teacher attrition rates, which in turn affects access to well-trained teachers, and lack of school resources.

This paper investigates classroom-related factors such as pedagogical strategies and management of robotics-based educational content that contribute to the formation of student perceptions in robotics-enhanced classes. Robots are becoming increasingly ubiquitous in K-12 classroom in the United States and are used to improve student engagement, interactive learning, innovative thinking, collaboration, problem-solving skills, language learning, and achievement scores.

Graphs illustrating complex scientific relationships require students to integrate multiple concepts and visual features into a coherent understanding. We investigate ways to support students in integrating their understanding of density concepts through a graph that is linked to a simulation depicting the relationship between mass, volume, and density. We randomly assigned 325 8^th-grade students to 1 of 2 graphing activities.

Graph technologies are now widely available in K-12 science and mathematics classrooms. These technologies have the potential to impact the learning of science and mathematics, especially by supporting student investigations. We use meta-analysis to analyze 42 design and comparison studies involving data from 7699 students spanning over 35 years. In these studies, graphing technologies include computer software such as simulations; online tools such as graph utilities; and sensors such as temperature probes. We characterize the assessments used to measure graphing.

In this paper we use practice theory, with its focus on the interplay of structure and agency, to theorize about teacher engagement in professional learning and teacher enactment of pedagogical practices as an alternative to framing implementation research in terms of program adherence and fidelity of implementation. Practice theory allowed us to reconsider assumptions about characteristics of effective teacher professional learning, and to rethink our own notions of agency.

Multimedia environments provide multiple resources for expression, collaboration, and knowledge-creation. Yet there is much to be learned about the design of such environments, the forms of collegial discourse that take place, and the benefits of participation. To this end, we study the 2017 STEM for All Video Showcase, a multimodal environment, that enabled educational researchers to share and discuss short videos depicting their federally-funded work to improve STEM education.

From 2012–2015, Advanced Placement (AP) science courses underwent a large-scale curricular reform to include more scientific inquiry and reasoning, reduce emphasis on broad content coverage, and focus on depth of understanding, with corresponding changes in high-stakes AP examinations. In this study, we explored how teachers prepared for and adapted to this reform over a three-year period. Data included four waves of individual interviews with 22 AP Biology and Chemistry teachers across the United States. Data were qualitatively analyzed using emic and etic coding.

Recent reforms in science education have supported the inclusion of engineering in K-12 curricula. To this end, many science classrooms have incorporated engineering units that include design tasks. Design is an integral part of engineering and helps students think in creative and interdisciplinary ways. In this study, we examined middle-school students’ naturally occurring design conversations in small design teams and their learning of science as a result of engaging in an engineering and science unit.
