Beyond the controversy: Instructional scaffolds to promote critical evaluation and understanding of Earth sciencePublication | 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.
Informing Estimates of Program Effects for Studies of Mathematics Professional Development Using Teacher Content Knowledge OutcomesPublication | 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 | The results from these analyses are intended to guide researchers in making more-informed decisions about the tradeoffs and considerations involved in selecting study designs for assessing the impacts of professional development programs.
- 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.
A Primer for Developing Measures of Science Content Knowledge for Small-Scale Research and Instructional UsePublication | 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.
Examining the sustainability of teacher learning following a year-long science professional development programme for inservice primary school teachersPublication | 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 the year following the...
Who Chooses STEM Careers? Using a Relative Cognitive Strength and Interest Model to Predict Careers in Science, Technology, Engineering, and MathematicsPublication | 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 accurate predictors of STEM...
- Publication | In this article, we review knowledge about student engagement and look ahead to the future of study in this area.
Motivational pathways to STEM career choices: Using expectancy-value perspective to understand individual and gender differences in STEM fieldsPublication | In this article, we conduct a literature review of the current knowledge surrounding individual and gender differences in STEM educational and career choices, using expectancy–value theory as a guiding framework.
Gender Gap in Science, Technology, Engineering, and Mathematics (STEM): Current Knowledge, Implications for Practice, Policy, and Future DirectionsPublication
- 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.
