This study developed an educational online game, Super Delivery, targeting knowledge about saving electricity, and conducted case studies of eight sixth-grade students using this game to explore the factors influencing the effectiveness of students' knowledge acquisition in digital game-based learning (DGBL). This study followed Miles and…

The purpose of this technical report is to describe a research study exploring students' cognitive processing while solving problems related to division of fractions. Four students were interviewed using verbal protocol techniques with the intention of better understanding their cognitive processing when dividing fractions. Information gained from…

Protocol analyses in research on writing reveal that throughout the composing process talented writers direct a tremendous amount of mental effort toward integrating and pursuing complex goals such as developing and following overriding themes, elaborating main points, clarifying content for a particular audience, and integrating genre features.…

The purpose of this article is to investigate the mathematical practice of proof validation--that is, the act of determining whether an argument constitutes a valid proof. The results of a study with 8 mathematicians are reported. The mathematicians were observed as they read purported mathematical proofs and made judgments about their validity;…

Background: Previous studies have suggested an association between reasoning strategies and diagnostic success, but the influence on this relationship of variables such as question format and task difficulty, has not been studied. Our objective was to study the association between question format, task difficulty, reasoning strategies and…

Building on previous studies of multiple text reading in history, this study aimed to contribute to that body of work by focusing on non-traditional multimodal sources. In an age of rapidly increasing access to and use of multimodal sources and a demand for reading and comprehending increasingly complex and specialized texts, it appeared there was…

Defining and measuring quality in group care settings has become a central issue in the field of early care and education in the United States, particularly as states develop systems to improve child care quality. Most research and policy definitions of quality rely on a top-down perspective focusing on structural and environmental features of the…

This article reports on an investigation into the different ways that pupils interact with technological artefacts. The results are discussed in the context of the need for first-year "introduction to engineering" courses to develop ways to provide students with an environment that facilitates their meaningful interaction with…

This study examined writers' use of their first language (L1) while writing in their second language (L2). Twenty students each wrote four short argumentative essays in their L1 (Dutch) and four in their L2 (English) under think-aloud conditions. We analysed whether L1 use varied between writers and tasks, and whether it was related to general…

In this article we present results of a Differential Item Functioning (DIF) study using Shealy and Stout's (1993) multidimensionality-based DIF analysis framework. In this framework, differences in test score distributions across different groups of examinees may be a result of multidimensionality if secondary dimensions (not the primary dimension…

In this study we explore the strategies that undergraduate and graduate chemistry students use when engaged in classification tasks involving symbolic and microscopic (particulate) representations of different chemical reactions. We were specifically interested in characterizing the basic features to which students pay attention when classifying…

Teaching a way of thinking requires making thinking visible. Educators need to pull back the curtains from historical cognition to show students not only what historians think, but "how" they think. Given that many students believe that history is a single story to be committed to memory and that texts speak for themselves, teaching historical…

This article reports on a study that examined the choice and use of academic reading strategies of adult learners who were identified as proficient and less proficient readers. The major objective was to explore the potential influence of their adult characteristics on their use of their academic reading strategies. Data were gathered using…

Students learned about electrical circuits in an arcade-type game consisting of 10 levels. For example, in one level students saw two circuits consisting of various batteries and resistors connected in series or parallel, and had to indicate which one had a higher rate of moving current. On levels 1-9, all students received a correct tone and had…

The purpose of this study was to describe how male, collegiate, certified athletic trainers (AT's) represent knowledge during 5 injury evaluation scenarios. A second purpose of the study was to identify what self-regulatory behaviors participants engaged in to improve or maintain their skills. Knowledge representation was studied as cue selection…
