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…

Emerging evidence attests to the need to intervene in young students' science motivation and achievement before their science motivation starts to dwindle. Heeding this call, we implemented a science utility value intervention for fifth and sixth graders in 23 classrooms (N = 550). Through five intervention sessions that consisted of diverse…

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…

The "leaky pipeline" with regard to students' engagement in Science, Technology, Engineering, and Mathematics (STEM) has triggered extensive research to understand and prevent students dropping out from STEM. To boost enrolment and interest in STEM fields, integrated STEM (iSTEM) education could be harnessed by providing students with…

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…

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…

We know little about why school administrators choose to adopt preventive mental health interventions within the context of school-based prevention trials. This study used a qualitative multiple-case study design to identify factors that influenced the adoption of a trauma-informed universal intervention by urban public school administrators…

This study's first purpose was to investigate effects of a fourth- and fifth-grade "next-generation" fraction intervention, which included six enhancements over a previously validated fraction intervention, designed to address career- and college-readiness standards. The study's second purpose was to assess effects of the next-generation…

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…

This study's 1st purpose was to investigate effects of a 4th- and 5th-grade "next-generation" fraction intervention, which included 6 enhancements over a previously validated fraction intervention, designed to address Career- and College-Readiness standards. The next-generation intervention is referred to as "Super Solvers."…

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…

Though emerging research supports the effectiveness of school-based coaching models utilizing motivational interviewing (MI), an examination of the specific drivers behind these effects is notably lacking in the prevention field. This study leveraged sequential analysis to examine how teachers' verbalization of change talk (i.e., language in…

Originally published as a special issue of the "Middle School Journal," this book presents integrative curriculum as a foundational element of the middle school. By addressing the current gap in literature on curriculum integration in the middle grades, this text explores how learning can be organized around authentic concepts or…
