This study investigated the relationship between the quality of peer assessment and the quality of student projects in a technology application course for teacher education students. Forty-three undergraduate student participants completed the assigned projects. During the peer assessment process, students first anonymously rated and commented on two randomly assigned peers' projects, and they were then asked to improve their projects based on the feedback they received. Two independent raters blindly evaluated student initial and final projects. Data analysis indicated that when controlling for the quality of the initial projects, there was a significant relationship between the quality of peer feedback students provided for others and the quality of the students' own final projects. However, no significant relationship was found between the quality of peer feedback students received and the quality of their own final projects. This finding supported a prior research claim that active engagement in reviewing peers' projects may facilitate student learning. Theoretical frameworkPeer assessment is a process in which students evaluate the performance or achievement of peers (Topping, Smith, Swanson & Elliot, 2000). This innovative assessment approach aims to empower students and foster active learning. Peer assessment can provide summative grading when students rate each other's performance. But many cases focus also on formative goals, such as promoting student learning. In most formative peer assessment models, students act as both assessors and assessees. As assessors, they review peers' work and provide constructive feedback. As assessees, students receive feedback and may make improvements accordingly. Through such processes, peer assessment becomes a strategy for formative assessment and a tool for reflection by students (Cheng & Warren, 1999).

Drawing from the contributions of vocational psychology, this study examined school engagement as a mediator of academic performance through the effects of career preparation (career planning, career decision-making self-efficacy), parental career support, and teacher support among diverse urban youth in middle school and high school ( N = 285). Based on structural equation modeling, all structural paths of the proposed hypothetical model were significant. The effects of teacher support and parental career support on school engagement were mediated by career preparation; in turn, the effect of career preparation on grades was mediated by school engagement. Teacher support also had a direct effect on school engagement.The middle school students had significantly higher grades than the high school students, but there were no significant grade-level differences in terms of school engagement, career preparation, parental career support, or teacher support.The limitations of the study and its implications for research, practice, and public policy are discussed.

The study examined how playing two roles as assessors and assessees in technologyassisted peer assessment contributes to students' performance. Data from a previous study was recoded and analysed to understand peer assessment processes from a different angle. Findings of our previous study supported the importance of the assessor's role, but not the assessee's role. In the present study, the assessee's role was re-examined based on the assessee's ability to critically judge and act upon peer feedback, instead of quality of peer feedback that they received. Regression analysis was conducted, and results suggested that how students responded to peer feedback, as indicated by the number of good versus misleading suggestions incorporated, significantly predicted their final project scores. The findings support the importance of both assessor and assessee's roles in peer assessment and provide valuable implications for effective implementation of peer assessment.

Abstract:The rapid development of computer and robotic technologies in the last decade is giving hope to perform earlier and more accurate diagnoses of the Autism Spectrum Disorder (ASD), and more effective, consistent, and cost-conscious treatment. Besides the reduced cost, the main benefit of using technology to facilitate treatment is that stimuli produced during each session of the treatment can be controlled, which not only guarantees consistency across different sessions, but also makes it possible to focus on a single phenomenon, which is difficult even for a trained professional to perform, and deliver the stimuli according to the treatment plan. In this article, we provide a comprehensive review of research on recent technology-facilitated diagnosis and treat of children and adults with ASD. Different from existing reviews on this topic, which predominantly concern clinical issues, we focus on the engineering perspective of autism studies. All technology facilitated systems used for autism studies can be modeled as human machine interactive systems where one or more participants would constitute as the human component, and a computer-based or a robotic-based system would be the machine component. Based on this model, we organize our review with the following questions: (1) What are presented to the participants in the studies and how are the content and delivery methods enabled by technologies? (2) How are the reactions/inputs collected from the participants in response to the stimuli in the studies? (3) Are the experimental procedure and programs presented to participants dynamically adjustable based on the responses from the participants, and if so, how? and (4) How are the programs assessed?

This study examined the construct validity of the Career Locus of Control Scale (CLCS) among diverse urban youth within the United States (N = 308). Confirmatory factor analyses verified two of the three models as acceptable fits. Two new models were also explored. Model 5 (Internality, Luck, and Non-Control), which was one of the new models, was the most useful explanation of the data. Abstract and concrete educational attitudes correlated with the CLCS subscales in a manner consistent with expectations. No significant differences in the CLCS subscales were found as a function of race; male students had significantly higher levels of concrete attitudes and scored significantly higher on Powerful Others than female students. Age was not related to Internality, abstract attitudes, or concrete attitudes but was significantly associated with Luck and Non-Control.
