Well-designed digital games hold promise as effective learning environments. However, designing games that support both learning and engagement without disrupting flow is quite tricky. In addition to including various game design features (e.g., interactive problem solving, adaptive challenges, and player control of gameplay) to engage players,…

In order to improve instruction, teachers need to make sense of and evaluate the critical events that have the potential to strengthen the understanding of students' mathematical thinking. Mathematics instruction has shifted toward inquiry teaching which leaves many teachers attempting to change their practices accordingly. While there are…

Many randomized controlled experiments in the classroom have found that mathematics learning is improved dramatically when practice problems of one kind are distributed across multiple assignments (spaced) and mixed with other kinds of problems (interleaved). In two studies, we investigated students' knowledge of spacing and interleaving. In Study…

Coaching is a complex endeavor that blends a myriad of concepts and skills. Practical experience, content knowledge, and coaching knowledge are instrumental to becoming an effective math coach. In order to design a professional development system to best support and build the capacity of coaches, we must identify what specific content and coaching…

The Lewis acid-base model is key to identifying and explaining the formation and breaking of bonds in a large number of reaction mechanisms taught in the sophomore-level year-long organic chemistry course. Understanding the model is, thus, essential to success in organic chemistry coursework. Concept-inventories exist to identify misunderstandings…

Decades of research have emphasized the need for engaging, accessible ways to help students learn fundamental mathematical concepts. Research also shows that teacher beliefs about teaching and learning have an outsized influence on the quality and effectiveness of curricular interventions. This article reports results of an independent evaluation…

A survey was conducted with 86 teachers across 10 states regarding their students' ease of use of physical manipulatives incorporated with implementing evidence-based early numeracy instruction. The majority of respondents indicated significant student accessibility barriers. Specifically, 75% of respondents had students with tactile defensiveness…

The dissertation, with a collected papers approach, focused on evaluating the implementation of MI curriculum in high school Biology I classes in south Florida. The dissertation included the development and validation of the Biology Identity and Persistence Survey (BIPS), the connection of instructors' teaching practices with students' biology…

This study investigated the effects of two instructional approaches -- Discovery Learning Scientific Community Laboratories (DL-SCL; Treatment) and non-DLSCL laboratories (Control) -- on students' conceptual understanding, epistemological views, and academic achievement in a Physics-1 lab. Conceptual understanding was measured pre/post using the…

Even though science says genetically modified (GM) foods are safe, many consumers remain skeptical of the technology. Additionally, the scientific community has trouble communicating to the public, causing consumers to make uninformed decisions. The Millennial Generation will have more buying power than any other generation before them, and more…

The purpose of this study was to examine the knowledge, skills, and dispositions enabled for elementary school participants in two summer herpetology programs, one in North Carolina and one in Florida. An additional purpose of this study was to examine the normative scientific practices in which participants engaged and to describe how these…

This document was prepared to assist literacy specialists in the national Regional Comprehensive Center network as they work with states to improve educational policy and practice in the area of adolescent literacy. It comprises three major parts: Part One: "Improving academic literacy instruction for students in grades 4-12." Based on…

This article presents the results of a 7th-grade classroom teaching experiment that supported students' understanding of integer addition and subtraction. The experiment was conducted to test and revise a hypothetical learning trajectory so as to propose a potential instructional theory for integer addition and subtraction. The instructional…

"ECHOS: Early Childhood Hands-On Science" was developed at the Miami Science Museum as a comprehensive set of science lessons sequenced to lead children toward a deeper understanding of science content and the use of science process skills. The purpose of the research is to determine whether use of the "ECHOS" model will…

In the first study of its type, students (N=197) were exposed to a television economics lecture which included specially-made segments having greater visual impact. Results indicate a significant difference in achievement in favor of students viewing this television lecture format. Positive attitude changes were also noted. (JN)
