DRK-12 Research and Products
Publication | This framework offers a clear picture of what exactly inclusive STEM schools are and common language for both researchers and practitioners.
Publication | In the Model- Evidence Link (MEL) diagram activities, students engage with Earth science content knowledge and evaluate the connections between evidence and alternative explanations. We have developed a rubric for assessing the quality of…
Publication | The two models presented in the Fracking MEL allow students to engage in scientific discussions just as researchers also examine relations between fracking and earthquakes.
Publication | This article describes how a Model-Evidence Link (MEL) lesson can effectively be used to assist learners in weighing the plausibility of different viewpoints of the uses of wetlands, a socio-scientific issue.
Publication | By evaluating alternative models, students can improve upon their scientific literacy and understanding of scientific practices. Suggestions from classroom use of the Moon MEL will help teachers use this activity in a productive manner.
Publication | Our project team has been developing and testing four MELs about socio-scientific issues (climate change, wetlands and land use, fracking and earthquakes) and abstract ideas (formation of Earth’s Moon) for use in high school classrooms.
Publication | This article presents a framework for calculating statistical power for moderator effects at all levels for two- and three-level CRTs.
Publication | This study presents empirical estimates of average program change in MKT and its variation with the goal of supporting the design of experimental trials that are adequately powered to detect a specified program effect.
Publication | In this study, we explore whether instruction on mapping directed magnitudes to operations helps 88 second graders and 70 fourth graders solve addition and subtraction problems with negative numbers.
Publication | In this study, we explore four, second graders’ performances on integer addition problems before and after analyzing contrasting cases involving integers.
Publication | This essay, intended for faculty involved in small-scale projects, courses, or educational research, provides a step-by-step guide to the process of developing, scoring, and validating high-quality content knowledge assessments.
Publication | The study examined patterns of change in primary school teachers’ inquiry practices, inquiry beliefs and physical science content knowledge during both years as well as the effects of school-level and individual-level factors on these changes in…
Publication | While past research has mainly focused on absolute cognitive ability levels in math and verbal domains, the current study tested whether relative cognitive strengths and interests in math, science, and verbal domains in high school were more…
Publication | In this study, we conducted in-depth interviews with 106 students from sixth to twelfth grade and 34 middle and high school teachers about how they conceptualized math and science engagement and disengagement.
Publication | This paper describes a model for differentiating professional development to address teachers’ varied knowledge, experiences, and interests.
Publication | In this study, we analyze log data to examine the granularity of students’ interactions with automated scores and feedback and investigate the association between various students’ behaviors and their science performance
Publication | The main goal of this project is to empirically estimate whether and which classroom factors contribute to mathematics gains of English Language Learners in Texas schools.
Publication | This paper describes a strategic process for using formative assessment probes to gather and interpret evidence of student mathematics understandings and misconceptions and then targeting instruction to address identified needs.
Publication | This article describes the use of RD design to evaluate the impact of a supplemental algebra-readiness curriculum, Transition to Algebra, on students’ mathematics outcomes.
Publication | This study tests that logic model by comparing the high school experiences and achievement of students in ISHSs and comparison schools in North Carolina.
Publication | This case study contributes to efforts to characterize teaching that is responsive to children’s mathematical thinking.
Publication | This paper outlines the development of a mobile application executing on a tablet device, which renders an immersive AR-based graphical user interface to enable users to monitor, interact with, and control a four link underactuated planar robot…
Publication | This paper presents the development of an immersive user interface on a tablet device that can be used by engineering students to interact with a motor test-bed as they examine the effects of discrete-time pole locations on the closed-loop…
