Abstract:
The goal of the present study was to examine the mechanisms underlying a strategy that we developed to make instructional explanations effective. In two experiments participants learned about plate tectonics from a multimedia material, including adjunct explanations that revised common misunderstandings. These explanations were either marked (including a device that pointed out the misunderstanding that the explanation was intended to revise) or unmarked. In both experiments participants receiving marked revising explanations outperformed those receiving unmarked ones in retention and transfer. In Experiment 1, think-aloud protocols revealed that marked revising explanations enabled learners to detect and repair flaws in their understanding more frequently than unmarked explanations. In Experiment 2, time recordings revealed that participants in the marked condition spent more time processing the revising explanations. Overall, the results mean that the revising instructional explanations that point out learners' misunderstandings promote a revision-oriented processing, in which learners monitor and revise their own understanding.

Abstract:
Students are frequently presented with novel visualizations introducing scientific concepts and processes normally unobservable to the naked eye. Despite being unfamiliar, students are expected to understand and employ the visualizations to solve problems. Domain experts exhibit more competency than novices when using complex visualizations, but less is known about how and when learners develop representational fluency. This project examined students' moment-by-moment adoption patterns for scientific visualizations. In a laboratory experiment, introductory-level organic chemistry students viewed familiar ball-and-stick and novel electrostatic potential map representations while solving chemistry problems. Eye movement patterns, verbal explanations, and individual difference analyses showed that students initially relied on familiar representations, particularly for difficult questions. However, as the task unfolded, students with more prior knowledge began relying upon the novel visualizations. These results indicate adoption and fluent use of visualizations is not given; rather, it is a function of prior knowledge and unfolding experience with presented content. (Contains 4 figures.)

Abstract:
Emerging technologies and student information technology literacy are enabling new methods of teaching and learning for clinical skill performance. Facilitating experiential practice and reflection on performance through student self-video, and exposure to peer benchmarks, may promote greater levels of skill competency. This study examines the impact of student self-video on the attainment of clinical skills. A total of 60 Physiotherapy students (100%) consented to participate in the randomised controlled trial. One group (50%) was taught a complex clinical skill with regular practical tutoring, whilst the other group (50%) supplemented the tutoring with a self-video task aimed at promoting reflection on performance. Student skill performance was measured in an objective structured clinical examination (OSCE). Students also completed an anonymous questionnaire, which explored their perception of their learning experiences. Students received significantly higher scores in the OSCE when the examined clinical skill had been supplemented with a self-video of performance task (P = 0.048). Descriptive analysis of the questionnaires relating to student perceptions on the teaching methods identified that the self-video of performance task utilised contributed to improvement in their clinical performance and their confidence for future clinical practice. Students identified a number of aspects of the submission process that contributed to this perception of educational value. The novel results of this study demonstrate that greater clinical skill competency is achieved when traditional tutoring methods are supplemented with student self-video of performance tasks. Additional benefits included the ability of staff and students to monitor longitudinal performance, and an increase in feedback opportunities.

Abstract:
Effective education of practical skills can alter clinician behaviour, positively influence patient outcomes, and reduce the risk of patient harm. This study compares the efficacy of two innovative practical skill teaching methods, against a traditional teaching method. Year three pre-clinical physiotherapy students consented to participate in a randomised controlled trial, with concealed allocation and blinded participants and outcome assessment. Each of the three randomly allocated groups were exposed to a different practical skills teaching method (traditional, pre-recorded video tutorial or student self-video) for two specific practical skills during the semester. Clinical performance was assessed using an objective structured clinical examination (OSCE). The students were also administered a questionnaire to gain the participants level of satisfaction with the teaching method, and their perceptions of the teaching methods educational value. There were no significant differences in clinical performance between the three practical skill teaching methods as measured in the OSCE, or for student ratings of satisfaction. A significant difference existed between the methods for the student ratings of perceived educational value, with the teaching approaches of pre-recorded video tutorial and student self-video being rated higher than "traditional" live tutoring. Alternative teaching methods to traditional live tutoring can produce equivalent learning outcomes when applied to the practical skill development of undergraduate health professional students. The use of alternative practical skill teaching methods may allow for greater flexibility for both staff and infrastructure resource allocation.

Abstract:
Betty's Brain is an open-ended learning environment in which students learn about science topics by teaching a virtual agent named Betty through the construction of a visual causal map that represents the relevant science phenomena. The task is complex, and success requires the use of metacognitive strategies that support knowledge acquisition, causal map construction, and progress monitoring. Previous research has established that middle school students struggle at such tasks without proper scaffolding and feedback. In Betty's Brain, this feedback is provided by Betty and Mr. Davis, another virtual agent designed to provide guidance and suggestions as students work. This paper discusses our implementation of contextualized conversational (CC) feedback, and then presents the results of an experimental study exploring the effects of this feedback in two 8th-grade science classrooms. The results illustrate some advantages of the CC feedback in comparison with a baseline dialogue mechanism that presents similar strategies in a non-conversational, non-contextualized form. While both groups showed significant pre-to-post test learning gains, the difference in learning gains between the groups was not statistically significant. However, students who received CC feedback more often performed actions in accordance with the advised strategies, and they created higher quality causal maps.

Abstract:
Research on simulator training has rarely focused on the way simulated contexts are constructed collaboratively. This study sheds light on how structuring role-play and fostering social interactions may prove fruitful for designing simulator training. The article reports on a qualitative study of nautical students training in a ship simulator. The study examines how a group of students, together with a professional maritime pilot, enacted professional roles and collaboratively constructed a simulated context for learning to navigate. Their activities on the bridge were framed within the maritime profession's hierarchical system of captain and officers, and we examine in detail how these institutionally defined positions become important resources for meaning-making during role-play. The article portrays how two competing activity contexts were constructed, and how the role-play provided opportunities for enacting professional roles and work tasks. However, it also shows that it is challenging to pick up on what is significant to learn and to confront this in debriefing. The article concludes that the students' collaboration and meaning-making is an entity of training that may be more efficiently addressed.

Abstract:
In this paper we examine how two groups of middle school students arrive at shared understandings of and solutions to mathematical problems. Our data consists of logs of student participation in the Virtual Math Teams (VMT) system as they work on math problems. The project supports interaction both through chat and through a virtual whiteboard. We have examined in detail, the sequential work these students do to constitute and specify "the problem" on which they are working in the ways they produce whiteboard objects and text postings. Solutions emerge as students come to understand the problem on which they are working. This understanding is achieved through gradual respecification of the math problem on which they are working.

Abstract:
This article reports a theory-driven experimental study that evaluates the effects of an annotation functionality on online social interaction and individual learning outcomes. The central hypothesis of this study is that directly addressing a part of a text by annotating it and then connecting each annotation with its related discussion can decrease coordinative interaction costs and result in a higher-quality discussion that favors greater gains in individual learning outcomes. To reach our objective, we carried out a theory-driven experimental study that compares two versions of an anchored discussion system: one with annotation functionality and one without it, both displaying the learning material side by side with its associated discussion in one window. Participants were 106 students enrolled in two sections of a blended-format course in health education. We assigned each section to a software condition. The examination of students' online social interaction centered on a fine-grained content analysis of coordination and knowledge construction activities as well as sequential analysis of knowledge construction activities. The results indicate that annotation functionality decreased coordinative interaction costs and stimulated more elaborated discussions that favored greater gains in individual learning outcomes. Implications for research and practice are discussed. Note:The following two links are not-applicable for text-based browsers or screen-reading software. Show Hide Full Abstract

Abstract:
This article is based on a systematic review of educational research, policy and professional literature relating to creative environments for learning in schools. Despite the search yielding 210 documents, comparatively few empirical studies were published between 2005 and 2011 that addressed the review objectives. Only 18 studies included in the review investigated the impact of creativity on learners. There was, however, some evidence for the impact of creative learning environments on pupil attainment, confidence, resilience, motivation, problem-solving, interpersonal skills and school attendance. These findings have implications for policy, practice and research internationally. Note:The following two links are not-applicable for text-based browsers or screen-reading software.

Abstract:
The increased accessibility of technology and Internet connections has enabled organizations to provide their workforces with the opportunity to engage in distributed education. "Harnessing this innovation calls for organizational and technological infrastructures that support the interplay of knowledge and knowing" (Cook & Brown, 1999, p. 381). This article explores the evidence of knowledge convergence in online knowledge-based communities of practice (CoPs). Learning outcomes assessed declarative knowledge, convergence, and knowledge application. A comparison group (self-paced design) was used to draw conclusions about the differential effects of knowledge-building strategies on these learning outcomes. The results show there was a difference in pretest and posttest scores and positive evidence of knowledge convergence. The findings pointed to higher posttest scores and higher level of convergence in the online CoP strategy. (Contains 6 tables and 7 figures.)
