Locus of control and tutor's instructional style as determinants of cross-age tutoring effectiveness

Junior high students serving as cross-age tutors taught their elementary school tutee an analogy lesson in the presence of observers who recorded tutor teaching behaviors and tutee learning as a function of students' internal-external control. Based upon results demonstrating that externals outperform internals when another person provides feedback regarding response accuracy, it was hypothesized that tutorial instruction would benefit external learners more than internal learners. Correlations between tutee externality and task performance (though in the expected direction) were not significant and failed to support the hypothesis. On the other hand, hypotheses regarding tutor behaviors were confirmed. As predicted, internal tutors expected to be more successful teachers, used more verbal and nonverbal cues in their teaching, expended more noticeable effort, and taught more analogies than external tutors. The implications of these results for the conduct of tutoring programs in schools was discussed.     

The Early Development Instrument as an Evaluation and Improvement Tool for School-Based,Integrated Services for Young Children and Parents: The Toronto First Duty Project

Research Findings: Integrated services for young children and families are part of the new policy landscape in early childhood, but there is limited evidence of the effectiveness of these programs and how they develop on the ground. This study examined the use of the Early Development Instrument (EDI) as both a summative program evaluation tool and as a formative program improvement tool supporting practitioners in Toronto First Duty, an integrated services demonstration project that combined kindergarten, child care, and parenting supports in public schools. Pre-post comparisons at community demonstration sites and comparisons with matched community sites using the EDI suggested that the demonstration program was associated with modest improvements in emotional and social domains of children's development. Mixed methods and multiple measures were used to contextualize summative findings in case studies across demonstration sites. The case studies explored how integration was implemented at different sites and how dimensions of enacted integration might contribute to positive outcomes for children and families. A case study of one site showed how an integrated staff team used EDI school-level profiles, along with formative feedback on program quality, to target and improve programming. Over the course of implementation, the integrated program environment quality ratings and EDI scores improved in relevant areas assessing quality of interaction and social–emotional development. Practice or Policy: Findings are discussed in terms of the role of the EDI in program evaluation and in improvement of practice. The potential value of integrated early childhood services and the challenges of evaluating complex community initiatives are also discussed.     

Ancient materials specificities for their synchrotron examination and insights into their epistemological implications

The synchrotron characterisation of archaeological and heritage materials has undergone a steep development in the past years, among a range of other advanced characterisation techniques. For synchrotron techniques alone, close to a hundred articles were published in 2011 on such materials, prompting new developments at large scale facilities. However, few publications have discussed the speci?c characteristics of heritage materials in their advanced spectroscopic and imaging study. Here, we suggest that a greater consideration be put on the speci?cities of ancient materials and their theoretical implications on the analytical process. In particular, we discuss the importance of the a posteriori framework of the study of heterogeneous materials considered in their historicity as structuring parameters of their study. Major implications are the relevance of trace analyses, those of majors and we suggest, more importantly, the dynamics between both endpoints. The on-going development of multimodal spectral imaging appears as a way to better address corresponding difficulties. Epistemologically, we suggest that a re?exive approach be developed to explain, structure and possibly contribute to narrowing down the ?eld of possible methodological research.     

Tangible User Interfaces and Contrasting Cases as a Preparation for Future Learning

In this paper, we describe an experiment that compared the use of a Tangible User Interface (physical objects augmented with digital information) and a set of Contrasting Cases as a preparation for future learning. We carried out an experiment (N?=?40) with a 2?×?2 design: the first factor compared traditional instruction (“Tell & Practice”) with a constructivist activity designed using the Preparation for Future Learning framework (PFL). The second factor contrasted state-of-the-art PFL learning activity (i.e., students studying Contrasting Cases) with an interactive tabletop featuring digitally enhanced manipulatives. In agreement with prior work, we found that dyads of students who followed the PFL activity achieved significantly higher learning gains compared to their peers who followed a traditional “Tell & Practice” instruction (large effect size). A similar effect was found in favor of the interactive tabletop compared to the Contrasting Cases (small-to-moderate effect size). We discuss implications for designing socio-constructivist activities using new computer interfaces.     

Interaction between television and child-related characteristics as demonstrated by eye movement research

Do field independent individuals and good readers exhibit more proficient scanning strategies than field dependents and poor readers? This study sought to answer those questions as well as to determine whether a dynamic rather than a static presentation leads to better scanning techniques. Measurements of the eye movements of third grade chi Idren as they viewed segments of The Electric Company television program were analyzed in terms of time taken to orient to target, percentage of fixations on target, percentage of time on target, direction of attack, and duration of fixation on target.     

Academic integrity in web based distance education

Conclusion This paper has identified a major gap in the research revolving around academic integrity/dishonesty and WBDE. Statistical evidence and empirical data are almost nonexistent. However, the evidence and data that do exist, strongly challenge many widespread assumptions related to the lack of integrity and the widespread dishonesty that are assumed to exist in WBDE today. Considering the continuing unprecedented growth of distance education, the extremely limited amount of statistical data available on this topic and the implications associated with the (possibly incorrect) assumptions of academic integrity in this environment, it seems that there is a critical need for further study. In the meantime, educational institutions can feel confident about the academic security of their WBDE programs by implementing the few safeguards suggested in this article to protect against dishonesty
