This study investigates the impact of an informal science outreach programme built around theories of identity formation and self-efficacy on middle school girls' science affinities. A lottery-based, randomised control trial was used to identify programme effects on four science affinity outcomes: science interests, efficacy with science, science…

This study presents an exemplar for psychometric evaluation and modification of established measures when applied to new populations. Specifically, we describe the use of two subscales (Career Decision-Making Self-Efficacy Scale and Math/Science Self-Efficacy Scale) from the Middle School Self-Efficacy Scale (MSSES) as outcome measures in an…

U.S. national data show that American Indians earn lower math and science scores than other ethnic/racial groups. In the current study, a brief, self-affirmation intervention was aimed at increasing science motivational beliefs in American Indian middle school students (n = 212, M[subscript age] = 12.7 years). Students, each read a biography of a…

This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…

My dissertation is a pre-mid-post-test, quantitative research design, including surveys and written assessments, to answer these research questions: 1. How do students' science mindset vary over time when engaged in science inquiry activities? Is there a difference between male and female students? 2. Is there a relationship between 7th grade…

Purpose: The authors tested the efficacy of a team-based instructional leadership intervention designed to increase middle school mathematics and science teachers' use of educational technologies for multiple representations of content to foster students' conceptual understandings. Each school's leadership team comprised an administrator, a…

Findings from recent studies suggest that students' pathways into mathematics-related careers begin as early as middle school when students are forming lasting self-perceptions of their academic abilities. Middle school is also a time when students begin making choices about future coursework in math, science, and technology that will have…

Although many agree that writing can make a unique contribution to learning, harnessing that contribution is difficult, particularly in the middle grades. The purpose of this study was to measure the efficacy of a feasible writing-to-learn intervention in Grade 6-11 science classes. We focused on middle school students because this group has been…

As climate change becomes an increasingly important topic for science educators, it is critical to learn how teachers may be able to increase students' knowledge about it. We conducted two consecutive quasi-experimental studies that investigated the role of interest in predicting middle school students' knowledge gains from a unit about how…

In "Small Teaching K-8," a team of veteran educators bridges the gap between cognitive theory and the K-8 classroom environment, applying the same foundational research found in author James Lang's bestselling "Small Teaching: Everyday Lessons from the Science of Learning" to the elementary and middle school setting. Via clear…

Communicative self-efficacy serves as an important link between discussing controversial issues and civic engagement because confidence in one's discourse skills is important to managing conflicting perspectives and developing solutions to community-based problems. Freely available to schools, "Word Generation" is a cross-content…

Research has demonstrated the efficacy of mentoring at-risk students in a number of fields from physical education to math and science. While separate research has found that many at-risk students lack effective communication skills, little research has explored the potential of communication mentoring in improving at-risk students' communication…

Video-based modeling is an evidence-based practice for teaching social and communication skills, functional and daily living skills, and some academic skills to students with autism spectrum disorder. The efficacy of video-based modeling, however, has not yet been established for STEM skills related to science, technology, or engineering. Drawing…

A binational team of investigators culturally adapted, implemented, and tested the efficacy in Mexico of "keepin' it REAL," a US-designed prevention intervention for youth. This article reports on the social validity of the adapted intervention by assessing its feasibility, acceptability, and utility, as perceived by participating middle…

Purpose: Adolescent females continue to face health consequences associated with risky sexual behaviors such as unintended pregnancies and sexually transmitted diseases. The purpose of this study was to investigate the efficacy of a gender-specific intervention targeted to early adolescent females. Method: This study used an intent to treat…
