We discuss an original study and two replications conducted over 18 years examining the impact of Teacher Study Group (TSG) in Vocabulary, a professional development (PD) approach for improving pedagogy and student learning. Study 1 focused on the design and development of the PD and included a small-scale randomized controlled trial to assess the…

Several studies and assumptions support the advantages of presenting pictures before texts, such as the Sequencing Effects of Integrated Model of Text and Picture Comprehension (the Sequencing Effects of ITPC Model) and the Scaffolding Assumption. However, few studies have examined the efficacy of text-first or picture-first multimodal input on…

The Precipitating Change Project was a 5-year development, implementation, and research study of an innovative 4-week middle school curricular unit in computational weather forecasting that integrates students' learning and use of meteorology and computational thinking (CT) concepts and practices. The project produced a list of CT skills and…

Imagine walking into an 8th-grade science classroom and hearing a discussion among students about a challenging assignment they recently completed. A pilot program in 18 Tennessee schools develops agency through competency-based education. Students in Beth Hines' 8th grade physical science class at West Collierville Middle School in Tennessee are…

Math anxiety's negative effects on performance are well-documented. The interplay of math anxiety and mathematical competence regarding later performance is underexplored. We investigated whether math anxiety's detrimental effects on learning depend on previous mathematical competence. Hypothesizing a moderation effect, we expected that trait math…

The application of knowledge to new contexts (i.e., transfer) is a central aim of learning processes and has become a new focus of testing effect research. In a quasi-experimental design, we investigated the transfer of retrieval practice effects on English vocabulary learning on eighth-grade students (N = 182) by applying a typical testing effect…

In this paper, we explore how students' algebraic noticing's and explanations changed across a two-year period with the introduction of designed instructional material. The data in this report is drawn from n=53 Year 7-8 students' responses to a free-response assessment task across two different years. Analysis focused on how students noticed and…

Playground Physics is a supplemental middle school science program designed to support embodied learning by enabling students to connect physics concepts to their own playful activities. The purpose of this study was to examine a model for scaling up the Playground Physics program and to determine the program's impact on middle school students'…

Examining the connections among teacher characteristics, instructional decision-making, and student learning in social studies education are both complicated and contentious. In the current study, we shed light on middle grades social studies teaching and learning--a black hole of research in the subject area. Using data from the National…

This research aims to investigate the impact of Common Knowledge Construction Model (CKCM) based science education teaching on the entrepreneurship skills of the eight grade students. The participants of this research are 50 students; 25 in control group (10 girls and 15 boys) and 25 in experimental group (9 girls and 16 boys). Quasi-experimental…

The potential spillover effects of the United States' opioid epidemic on children's educational outcomes have received surprisingly little attention from researchers. Accordingly, this study leverages national datasets of county-level opioid prescription rates and public school students' third- to eighth-grade academic achievement to provide the…

A longstanding aim of education efforts to position students as knowledge constructors so they are engaged in the building and shaping their learning environment. Current education reforms situate student sense making around authentic science inquiries where students are engaged in the practices of science. In the science classroom, this means…

The university aims to form professionals through transmission and dissemination of knowledge, therefore, the Extension, as a tool of the universities, has a major role contributing to improvements in the learning and teaching process. The Extension projects are extremely important for The Federal Technological University of Paraná (UTFPR), since…

This Teaching and Learning Research Initiative (TLRI) project was a 2-year exploratory study focusing on differentiating the curriculum in response to individual learner differences. The project was designed to explore learning and teaching of differentiated scientific content through observational processes and the expression of that learning…

The present study investigated the effects of online argumentation scaffolding on students' argumentation involving hypothetical and theoretical biological concepts. Two types of scaffolding were developed in order to improve student argumentation: continuous scaffolding and withdraw scaffolding. A quasi-experimental design was used with four…
