Early science learning with a virtual tutor through multimedia explanations and feedback on spoken questions

The purpose of this pilot study with a within-subject design was to gain a deeper understanding about the promise and restrictions of a virtual tutoring system designed to teach science to first grade students in Finland. Participants were 61 students who received six tutoring science sessions of approximately 20 min each. Sessions consisted of a sequence of narrated multimedia science presentations during which a virtual tutor explained science phenomena displayed in pictures. Narrated science explanations were followed by one or more multiple choice questions with immediate feedback about students’ choices and a possible second attempt, during which students reached 97% accuracy. A pretest and posttest was administered to assess students’ ability to reason about the science and to transfer knowledge to new contexts. Results indicated significantly greater improvement in the understanding of the science concepts taught during the tutoring sessions, relative to the concepts that were not taught. Results from the surveys administered to teachers and students indicated that the program was well received. Detailed analysis of student error responses provided a deeper understanding about the complex interplay between students’ prior knowledge, the way topics were taught in the multimedia lessons, and the way learning was assessed. Findings from the quantitative and qualitative analyses are discussed in the context of designing high quality lessons delivered through a virtual tutoring system.     

Reciprocal peer tutoring in a physical education setting: influence of peer tutor training and gender on motor performance and self-efficacy outcomes

Students often do not take full advantage of peer tutoring instructional strategies because they are not sufficiently prepared to fulfill the role of tutor. This study examined whether implementing a peer tutor training program prior to the beginning of reciprocal peer tutoring (RPT) sessions might help overcome this issue. Gender differences were also explored. In a physical education setting, 48 novice ninth-graders were assigned in symmetric dyads to a physical practice associated with trained RPT condition (TRPT; n = 24) or a physical practice associated with spontaneous RPT condition (SRPT; n = 24). Moreover, 24 participants were assigned to a physical practice without any form of RPT control condition (PP). The peer tutor training, based on an original group interview technique, aimed at enhancing the explanatory potential of the tutor and his/her sensitivity to the specific needs of the tutee. Results indicated a superior motor performance for the TRPT condition and no difference between the SRPT and PP conditions. Interestingly, a positive relation between motor performance and self-efficacy beliefs was found for TRPT females. The assumption that the development of metacognitive awareness is one of the mechanisms underlying RPT’s effectiveness was thus supported.     

Effects of mobile-app learning diaries vs online training on specific self-regulated learning components

Self-regulated learning (SRL) is associated with increased academic achievement and improved learning outcomes for students. Thus, it is import to find ways to improve SRL, such as through training. Face-to-face training, discipline-dependent training, and paper-and-pencil diaries are limited in the number of students they can reach. The current randomised control study implemented discipline-independent online training and novel mobile-app based diaries and tested SRL motivation and perceived strategy use in 73 University students from mixed disciplines and study mode. Results showed that participants in the combined condition (training with diaries) improved more than other conditions. Specifically, they improved on SRL knowledge, metacognitive strategies, cognitive strategies (elaboration, organisation and critical thinking), and resources management strategies (time-management and effort regulation). The present study extends previous findings, showing that positive effects can be found for SRL when a discipline-independent approach is used coupled with online training and a mobile-app based daily diary.

     

Coping with school failure and self-regulated learning

The aim of the study was to explore whether students can be classified in groups according to their coping strategies in dealing with school failure and to assess relationships between coping strategies and various components of self regulated learning. The sample consisted of 470 high school students (15 to 18 years old). The students responded to two self-report questionnaires: The School Failure Coping Scale and The Components of Self-Regulated Learning.     

Epistemological beliefs and self-regulated learning with hypertext

This study investigated the relationship between epistemological beliefs, prior domain knowledge and self-regulated learning. Biology students (n?=?25) and humanities students (n?=?26) who varied in their epistemological beliefs learned with a hierarchical hypertext about the topic of genetic fingerprinting. During their learning processes, logfiles and questionnaire data were collected. Results indicate that students do metacognitively calibrate their learning process to the complexity of the presented learning material, e.g. by processing more complex deeper-level nodes longer. Furthermore, these calibration processes were significantly related to epistemological beliefs. For example, more ‘sophisticated’ epistemological beliefs were associated with processing more nodes, whereas more ‘naïve’ beliefs were related to spending more time on single nodes. Both effects were especially pronounced on deeper hierarchical hypertext levels. Prior domain knowledge also had an impact, especially on comprehensibility ratings: biology students considered all nodes more comprehensible than humanities students. Additionally, epistemological beliefs as well as prior domain knowledge were also significantly associated with the learning outcome: for example, more prior domain knowledge led to significantly higher learning outcome.     

The effect of peer feedback for blogging on college students' reflective learning processes

Reflection is an important prerequisite to making meaning of new information, and to advance from surface to deep learning. Strategies such as journal writing and peer feedback have been found to promote reflection as well as deep thinking and learning. This study used an empirical design to investigate the interaction effects of peer feedback and blogging on college students' reflective thinking skills and their learning approaches. Forty-four first- and second-year undergraduate students participated in the study. Students kept blogs each week throughout a whole semester. Two journals were sampled at the beginning and end of the semester for each student. A repeated measure one-way ANOVA suggested that students' reflective thinking level increased significantly over time; however, peer feedback was found to negatively affect students' reflective thinking skills. The result of the study suggests more carefully designed uses in the future.     

Instructional scaffolds for learning from formative peer assessment: effects of core task,peer feedback,and dialogue

Formative peer assessment is an instructional method that offers many opportunities to foster students’ learning with respect to both the domain of the core task and students’ assessment skills. The contributions to this special issue effectively address earlier calls for more research into instructional scaffolds and the implementation of dialogic features in formative peer assessment. However, open issues remain regarding the role of assessment criteria, the benefit of formative peer assessment for transferable knowledge and skills, the role of metacognitive and cognitive processes in the provision and reception of peer feedback, and the proposed benefit of more interactive forms of formative peer assessment. Addressing the latter issue in particular, a framework of three dimensions of increasing interactivity is proposed in order to guide future research. These three dimensions comprise the learner’s engagement with the core task (low interactivity), the provision and reception of peer feedback (medium interactivity), and the learner’s engagement with argumentation, tutoring, and co-construction in dialogue with peers (high interactivity).

The alignment of written peer feedback with draft problems and its impact on revision in peer assessment

Despite the wide use of peer assessment, questions about the helpfulness of peer feedback are frequently raised. In particular, it is unknown whether, how and to what extent peer feedback can help solve problems in initial texts in complex writing tasks. We investigated this research gap by focusing on the case of writing literature reviews in an academic writing course. The dataset includes two drafts from 21 students, sampled to represent a wide range of document qualities, and 84 anonymous peer reviews, involving 1,289 idea units. Our study revealed that: (1) at both substance and high prose levels, drafts of all quality levels demonstrated more common problems on advanced writing issues (e.g. counter-argument); (2) peer feedback was driven by difficulty of the problem rather than overall draft quality, peer comments were not well aligned with the relative frequency of problems, more comments were given to less difficult problems; (3) peer feedback had a moderate impact on revision, and importantly, receiving multiple comments on the same issue led to more repairs and improvement of draft quality, but consistent with the comments received, authors tended to fix basic problems more often. Implications for practice and research are drawn from these findings.     

The effects of cross-modality and level of self-regulated learning on knowledge acquisition with smartpads

Recently, there has been a transition from traditional paper or computer-based learning environments to smartpad-based learning environments, which are based on touch and involve various cognitive strategies such as touch operation and note taking. Accordingly, the use of smartpads can provide an effective learning environment through cross-modality, which simultaneously integrates information using two or more sensory modalities. Based on this rationale, this study investigated the effects of cross-modality (vision and tactility) on knowledge acquisition in a smartpad-based learning environment. Interaction between different modalities and learners’ self-regulated learning (SRL) skills was also tested. Ninety-nine college students were randomly assigned to three different learning environments: paper-based, smartpad-based unimodal, and smartpad-based cross-modal environments. Students were differentiated according to high and low SRL skill levels. The findings suggest that the participants in the smartpad-based cross-modal environment significantly outperformed the participants in the smartpad-based unimodal environment pertinent to identification and comprehension knowledge acquisition. Furthermore, the participants in the smartpad-based cross-modal environment performed equally with the participants in the paper-based environment.     

Multiple Approaches to Assessment: Reflections on use of tutor,peer and self-assessment

Assessment within higher education has traditionally been the sole responsibility of the tutor. This paper considers the authors' experience with the introduction of both selfassessment and peer-assessment into a literature module at a new UK university. This paper describes the practical aspects and examines the outcomes. Reflections on the process are given for both students and tutor. It is concluded that, with careful application, the use of self-and peer assessment can yield positive educational benefits that more than justify any additional efforts required of students or tutor.

Effects of online note taking formats and self-monitoring prompts on learning from online text: Using technology to enhance self-regulated learning

This study explored conditions under which note taking methods and self-monitoring prompts are most effective for facilitating information collection and achievement in an online learning enviornment. In experiment 1 30 students collected notes from a website using an online conventional, outline, or matrix note taking tool. In experiment 2 119 students collected notes from a larger, more ecologically valid set of learning materials using the conventional, outline, or the matrix tool. One half of the students also received prompts designed to encourage self-monitoring. Results of both experiments indicated that the matrix note taking device was a superior tool for collecting information and for achievement. Results of experiment 2 indicated that self-monitoring prompts have a significant positive impact on notes taken and achievement as well. Results are discussed relative to self-regulated learning and perceptual enhancement theories.     

Interactive and non-interactive pictures in multimedia learning environments: Effects on learning outcomes and learning efficiency

New technologies enable flexible combinations of text and interactive or non-interactive pictures. The aim of the present study was to investigate (a) whether adding pictures to texts is generally beneficial for learning or whether it can also have detrimental effects, (b) how interactivity of pictures affects learning, (c) whether the visualization format of pictures affects the structure of the learner's mental model, and (d) whether the visualization format modifies the effects of interactivity. One hundred university students were randomly assigned to five groups. In four groups, a text about the different daytimes and days on the earth was combined with interactive or non-interactive pictures of different visualization formats. In the fifth group, the text was presented without pictures. According to the results, adding pictures to text was neither beneficial nor harmful for learning. In terms of learning efficiency, however, learning from text only was more successful than learning from text and pictures. Interactivity was beneficial for one learning task, but not for the other task. The visualization format affected participants’ interaction with pictures, but not the learning outcomes; however this effect was not influenced by interactivity. Implications for multimedia design and for further research are pointed out.
