A student might find a certain representational format (e.g., diagram, text) more attractive than other formats for learning. Computer technology offers opportunities to adjust the formats used in learning environments to the preferences of individual learners. The question addressed in the current study was: does the match between a student's…

Developing curriculum and instruction for mathematics education and designing technologically enhanced learning environments are often pursued separately, but may need to be addressed together to effectively link the strengths of technology to performance in mathematics and conceptual understanding. This paper addresses current challenges with…

High-stakes tests take time away from valuable learning activities, narrow the focus of instruction, and imply that science involves memorizing details rather than understanding the natural world. Current tests lead precollege instructors to postpone science inquiry activities until after the last standardized test is completed--often during the…

A Chemistry Concept Reasoning Test was created and validated providing an easy-to-use tool for measuring conceptual understanding and critical scientific thinking of general chemistry models and theories. The test is designed to measure concept understanding comparable to that found in free-response questions requiring explanations over…

In this paper we describe the development and refinement of "evidence rules" and "measurement models" within the "evidence model" of the "evidence-centered design" (ECD) framework in the context of the "Packet Tracer" digital learning environment of the "Cisco Networking Academy." Using…

This study examined differences between two groups of students' spatial-scientific reasoning from pre to post implementation of an Earth/Space unit. Using a quasi-experimental design, researchers explored how instructional method and gender affected learning. Treatment teachers employed an integrated STEM curriculum while the control teacher…

Human behavior representation (HBR) models simulate human behaviors and responses. The Joint Crowd Federate [TM] cognitive model developed by the Virginia Modeling, Analysis, and Simulation Center (VMASC) and licensed by WernerAnderson, Inc., models the cognitive behavior of crowds to provide credible crowd behavior in support of military…

The present article discusses the design and impact of computer-based visualization tools for supporting student learning and representational competence in science. Specifically, learning outcomes and student representation use are compared between eight secondary classrooms utilizing The Connected Chemistry Curriculum and eight secondary…

This study reports the strategies used by second language learners to comprehend computerized video material. In total, 211 students taking an English course in a public university in Taiwan joined the study, conducted over 1 academic year during which 63 students were involved in the pilot study in the first semester, and 148 joined the formal…

Learning by observing and imitating others has long been recognized as constituting a powerful learning strategy for humans. Recent findings from neuroscience research, more specifically on the mirror neuron system, begin to provide insight into the neural bases of learning by observation and imitation. These findings are discussed here, along…

This paper reports on a study examining the effects of visualizing online writing activities on student behaviors and learning outcomes. A design-based research approach was adopted to develop and integrate theory and practice in natural educational settings (Anderson & Shattuck, 2012). The study was conducted in an 18-week, semester-long…

The purpose of the two experiments was to investigate the potential effects of different types of visualizations and self-explanation prompts on learning human cardiovascular system in a multimedia environment. In Experiments 1 and 2, 70 and 44 college students were randomly assigned to one of the four conditions in a 2 × 2 factorial design with…

This study investigated the effectiveness of a unit plan designed to enhance students' three-dimensional geometry and spatial ability skills. Research participants consisted of 50 students, 19 males and 31 females, and two teachers from a public high school in a suburban middle-class community. The students in this study were 9th and 10th graders…

Visual representations are ubiquitous in modern-day science textbooks and have in recent years become an object of criticism and scrutiny. This article examines the extent to which changes in representations in textbooks published in the USA over the past six decades have invited those critiques. Drawing from a correlational analysis of a corpus…

How can we teach science to English language learners (ELLs) when even our native English speakers have trouble reading the textbook? To help science teachers meet this challenge, this article presents six text-comprehension strategies used by English for Speakers of other Languages (ESOL) teachers: metalinguistic awareness development,…
