The purpose of this quantitative retrospective study was to understand the impact of prior exposure to sexual health education on middle and high school students' sexual health knowledge, self-efficacy, and intentions. The study analyzed a secondary dataset that included pre- and posttest results collected for program evaluation purposes by a…

Success in chemistry requires not only the ability to recruit prior knowledge but also the ability to establish strong connections between new and existing concepts to form knowledge clusters around core principles. How these knowledge structures are organized can be used to understand the relationships between concepts within a student's mind.…

This study examines whether "My Math Academy," a digital game-based learning environment that provides personalized content and adaptive embedded assessments, can improve math knowledge of Transitional Kindergarten and Kindergarten students. A cluster randomized study was conducted with 20 classrooms, 10 of which were randomly assigned…

In response to the increasing recognition of the need for sustainable food systems, research on students' and educators' knowledge of food systems and sustainability more broadly has grown but has generally focused on what people "fail" to understand. Moving away from this deficit approach, the present study used semi-structured…

This study examines factors impacting teacher learning during and after an online professional development program focused on teaching English language learners in U.S. schools. Research focused on nonbilingual K-12 teachers' changing perspectives on the role of students' native languages in classroom teaching and learning during and after the…

Reading comprehension--the ability to understand the meaning of text--is a foundational ability that enables children to learn in school and throughout life. Children who struggle with reading comprehension in the third or fourth grade are at high risk for dropping out of school, with detrimental effects on their future employment, income, and…

Problem solving is a highly valued skill in chemistry. Courses within this discipline place a substantial emphasis on problem-solving performance and tend to weigh such performance heavily in assessments of learning. Researchers have dedicated considerable effort investigating individual factors that influence problem-solving performance. The…

This study investigated how domain specifications controlled topic and rater reliability. History students completed three performance tasks. For each topic, they took prior knowledge tests, read primary materials, and wrote explanatory essays. Using a theory-based scoring rubric, four raters scored all essays. The rubric worked similarly on the…

"No Child Left Behind" (NCLB) attempts to ensure educational equity for all K-12 students. However, for the conceptual goals of NCLB to become reality, pre-service teacher training models must be modified to include a deeper understanding of individual differences and how these play out in classroom dynamics. The "Three Literacy…

To date the authors have completed 23 studies of knowledge monitoring and its relationship to learning from instruction. Their earlier work, 12 studies in all, is summarized and reported elsewhere (see Tobias and Everson, 1996; Tobias and Everson, 2000). In this paper they continue this line of research and summarize the results of 11 studies that…
