Design factors for educationally effective animations and simulations

This paper reviews research on learning from dynamic visual representations and offers principles for the design of animations and simulations that assure their educational effectiveness. In addition to established principles, new and revised design principle are presented that have been derived from recent research. Our review focuses on the visual design and interaction design of these visualizations and presents existing research as well as questions for future inquiry.

Moved to learn: The effects of interactivity in a Kinect-based literacy game for beginning readers

Reading to young children has a number of benefits, including supporting the acquisition of vocabulary and literacy skills. Digital reading games, including ones with new modes of interface such as the Kinect for Xbox, may provide similar benefits in part by allowing dynamic in-game activities. However, these activities may also be distracting and detract from learning. Children (ages 5-7 years, N = 39) were randomly assigned to either i) jointly read a story with an adult, ii) have the story read by a character in a Kinect game, or iii) have the story read by a character in a Kinect game plus in-game activities. Both Kinect-Activities and Book Reading groups had significant gains for High Frequency Words, Active Decoding, and Total Reading Score, but only Kinect-Activities group had significant gain for Sight words (p <.05). Overall, these findings are encouraging for the next generation of digital literacy games.

The effect of learning mechanics design on learning outcomes in a computer-based geometry game

A computer-based geometry game was adapted to allow for play using a conceptual rule or an arithmetic problem-solving mechanic. Participants (n = 91) from an urban middle school were randomly assigned to experimental conditions. Results suggest that play in the number condition was more situationally interesting than play in the rule condition. Participants in the rule condition were found to perform better in the game than those in the number condition. Learning outcome results suggest that in the number condition, but not the rule condition, playing more levels in the game diminishes the gain from pretest to posttest. For the design of games for learning, results highlight the importance of choosing a game mechanic that reflects the intended learning outcomes.

Reliability and validity of advanced theory-of-mind measures in middle childhood and adolescence

Although theory-of-mind (ToM) development is well documented for early childhood, there is increasing research investigating changes in ToM reasoning in middle childhood and adolescence. However, the psychometric properties of most advanced ToM measures for use with older children and adolescents have not been firmly established. We report on the reliability and validity of widely used, conventional measures of advanced ToM with this age group. Notable issues with both reliability and validity of several of the measures were evident in the findings. With regard to construct validity, results do not reveal a clear empirical commonality between tasks, and, after accounting for comprehension, developmental trends were evident in only one of the tasks investigated. Statement of contribution What is already known on this subject? Second-order false belief tasks have acceptable internal consistency. The Eyes Test has poor internal consistency. Validity of advanced theory-of-mind tasks is often based on the ability to distinguish clinical from typical groups. What does this study add? This study examines internal consistency across six widely used advanced theory-of-mind tasks. It investigates validity of tasks based on comprehension of items by typically developing individuals. It further assesses construct validity, or commonality between tasks.

Linguistic Mediation of Children's Performance in a New Symbolic Understanding Task

The effects of language on symbolic functioning were examined using the boxes task, a new symbolic understanding task based on DeLoaches model task. Children (N = 32; ages 2;4–3;8) observed an object being hidden in a stack of four boxes and were then asked to retrieve a similar object in the same location from a set of four target boxes. Each box was identified with a different object sitting on a small ledge in front of it. Language use was manipulated by providing linguistic scaffolding (naming vs. standard) and by using objects to identify the boxes whose names were either known or unknown to the children (familiar vs. language control). Home language environment (monolingual vs. bilingual) and verbal age (measured via the Peabody Picture Vocabulary Test-Third Edition) were also examined. Main effects were found for type of object (with familiar objects yielding better performance), home linguistic environment (with bilingualism resulting in better performance), and verbal age. There was also a verbal age × linguistic scaffolds interaction: Verbal age was related to correct retrievals only in the naming condition. These results provide further evidence that language mediates childrens symbolic development and indicate that the new boxes task is an effective way of evaluating young childrens symbolic competencies.
