DRK-12 Research and Products
Publication | The goal of this project was to create an inquiry activity to teach symmetry elements and symmetry operations in an inorganic chemistry course. Many students experience difficulty when building and mentally manipulating three-dimensional mental…
Publication | The central goal of this study was to create a new diagnostic tool to identify organic chemistry students’ alternative conceptions related to acid strength. Twenty years of research on secondary and college students’ conceptions about acids and…
Publication | Digital pen-and-paper technology, although marketed commercially as a bridge between old and new notetaking capabilities, synchronizes the collection of both written and audio data. This manuscript describes how this technology was used to…
Publication | This volume reflects upon how learners engage in the processes of problem solving and critical thinking by exploring the critical theories that undergird these processes; and this chapter introduces practitioners of educational technology to the…
Publication | This chapter concludes The role of criticism in understanding problem solving. In it, the overall message of the book—that criticism and critical theories can serve to aid critical reading and synthesis of the educational technology research…
Publication | Introductory biology courses form a cornerstone of undergraduate instruction. However, the predominantly used lecture approach fails to produce higher-order biology learning. Research shows that active learning strategies can increase student…
Publication | Despite evidence that it can help students learn higher-order thinking skills and gain deep content knowledge, problem-based learning (PBL) is not deployed on a large scale in K-12 classrooms. This conceptual chapter explores teacher’s past…
Publication | The concept of criticism as a tool for research, although well established in other educational research traditions, is not well established in the domain of Educational Technology. This book changes all that by substantiating criticism as a way…
Publication | Enzyme function is central to student understanding of multiple topics within the biochemistry curriculum. In particular, students must understand how enzymes and substrates interact with one another. This manuscript describes the development of…
Presentation | This intermediate session demonstrated how we conducted an a priori power analysis for a longitudinal,multisite cluster randomized trial of an early childhood science education program, then later revised it to accommodate budget changes…
Publication | Each DR K-12 project has formative and summative evaluation, which are different from the project’s own R&D activities and instead should support and measure the effectiveness of those activities. This paper discusses evaluation options for…
Publication, Tool | To foster knowledge use among policy makers or practitioners requires a substantial effort that invests in sustained interaction and enlists a range of supports for the prospective knowledge users. This paper discusses some options for…
Publication | This paper describes Supporting Research, Service and Teaching in Mathematics Education, or STaR, is a program designed to support new faculty who have taken a tenure-track mathematics education position in a U.S. institution of higher…
Publication | The Chemistry Education Research (CER) Doctoral Scholars Program trains a diverse group of graduate students how to develop assessments of secondary and tertiary students’ understandings of core concepts in chemistry.
Publication | This paper represents measurement methods of projects developing and testing intelligent learning environments.
Publication | The minus sign is a mathematical symbol that is multi-functional. Yet, how often is its use explicit to the non-mathematician, or more importantly the learner, who is expected to interpret the symbolism appropriately, when often the "meaning"…
Tool | Organized around six themes for establishing and nurturing successful partnerships, the Education R&D Partnership Tool includes a Work Sheet that prompts reflection and discussion on prominent issues, as well as a parallel Reference Sheet with…
Publication | This overview is intended to describe the scope and depth of research and development DR K-12 has funded and to identify areas that could be advanced by further investigations by CADRE. The overview summarizes the 248 projects that met the…
Publication | This brief suggests practical ways of engaging teachers and other “end-users” in projects that develop materials for education in the areas of science, technology, engineering, and math (STEM). Projects described in this brief have benefited…
