Role of teacher characteristics and school resources in early mathematics learning

The authors investigated the degree to which school-level teacher characteristics and resources are related to the mathematics learning of kindergarten children using a sample drawn from a large US database. Kindergarten-level teacher characteristics were operationalised as collective teacher efficacy, teacher experience and teacher preparation; kindergarten resources were operationalised as efforts that schools make to reach out to parents, classrooms with mathematics manipulatives, and classroom technology. Kindergarten students learned more in mathematics over a year in schools where teachers’ collective efficacy was high. School resources yielded a range of significant yet mixed results in young children’s mathematics achievement. Notably, younger students and students entering kindergarten with lower levels of mathematical skills benefited greatly from classroom resources. Overall, the presence of classroom technology as a school-level resource was positively related with older kindergarten students’ learning. Based upon the findings, organisational and policy implications are discussed.     

The Influence of Friends' Instant Messenger Status on Individuals' Coping and Support-Seeking

Although there is an increasing amount of research on social support in cyberspace, little is known about how Internet technologies influence social support among people who share offline personal relationships. The current study examined how friends' instant messenger (IM) status might influence individuals' coping and support-seeking, and what mechanisms could account for those effects. Four hundred and ninety-four college students read and responded to a hypothetical scenario in which they logged onto IM after experiencing a stressful situation. Participants perceived higher levels of self-efficacy, greater stress decrease, and greater likelihood of seeking support from a friend when the friend was said to be online than offline. Perceived social presence mediated the influence of a friend's online status on participants' coping and likelihood of seeking support from the friend.     

Focusing on the Whole Student: An Evaluation of Massachusetts's Wraparound Zone Initiative

We used a comparative interrupted time series design to examine the impact of the Massachusetts' Wraparound Zone Initiative on student achievement, attendance, retention, and suspension. This initiative was designed to create coordinated district systems that allow schools to proactively and systematically address students' nonacademic needs. The state education agency awarded grants to seven high-need districts, each of which used the funds to support a select group of schools in implementing strategies that focused on school climate and culture, family engagement, systems to identify and address student needs, and community partnerships. Results from this study showed that students in Wraparound Zone schools performed better on state academic assessments than students in comparison schools, when considering prior achievement trends. Effects were statistically significant in the 3rd year of implementation. The impact on academic achievement was greatest for third- and fourth-grade students, and was particularly strong for English learners. There was no statistically significant overall impact on attendance, retention, or suspension.     

The dimensions of e-learning quality: from the learner’s perspective

The present study was designed to identify the quality dimensions as perceived by adult learners who had taken one or more e-learning courses offered by higher education institutions in South Korea and to identify and confirm the structural features of these quality dimensions. The results of the exploratory factor analysis arising from a survey of 299 learners revealed that from their perspective, there were seven dimensions in evaluating the e-learning quality: Interaction, Staff Support, Institutional Quality Assurance Mechanism, Institutional Credibility, Learner Support, Information and Publicity and Learning Tasks. And the confirmatory factor analysis with responses obtained from another set of 496 adult learners confirmed a good fit of the seven-factor model to the observed data. While most of these seven dimensions are supported by previous studies, some dimensions, such as technology support, content and evaluation/assessment that e-learning providers had highlighted did not appear to be important for Korean adult learners. Possible explanations for these findings are discussed in relation to learner characteristics, e-learning design, and culture, and further research topics are suggested.     

Students’ perception of EdD and PhD programmes in Hong Kong

The aim of this study is to explore the learning experiences of students enrolled on a Doctorate in Education programme in Hong Kong. The main questions are as follows. How do EdD students position themselves as doctoral candidates? How do EdD students experience their education in terms of scholarly expertise and scholarly identity? How do EdD students characterise their relationships with their supervisors? What perceptions do PhD students hold of the field of knowledge of EdD students and the value of an EdD degree? The data obtained from 10 semi-structured interviews in one selected institution are discussed with reference to the four main themes; distinction between EdD and PhD degrees: ‘co-existent’ vs. ‘separate’; positioning of EdD programme: title of doctor as ‘unfair’ vs. ‘deserved’; scholarly value: ‘insightful’ vs. ‘non-academic’; and relationship with supervisor: ‘independent and self-managed’ vs. ‘never equal, unlike the relationship between PhD student and supervisor’.

     

Disposition assessment in teacher education: A framework and instrument for assessing technology disposition

Abstract

This study proposes and verifies the concept of a technology disposition in teacher education, which is comprised of predisposition and competence. It examines the reliability and validity of a measure of the technology disposition of teacher education students, the Technology Disposition Scale for Teacher Education Students (TDS‐T). The TDS‐T is comprised of two subscales: technology predisposition and technology competence. In this study, the TDS‐T was completed by 656 teacher education students. Results showed the proposed disposition model of predisposition and competence had significant relationships with gender and class year. Male students had significantly higher overall technology disposition scores than did female students, but these differences were due to the male students' strong self‐concept, especially self‐confidence. Students technology competence level was significantly higher for seniors than for sophomores, and the overall technology disposition scores significantly increased from students' junior to senior years. The TDS‐T demonstrated content validity through factor analysis and convergent and discriminate validity through item analysis. The value for Cronbach's alpha was .93, indicating highly satisfactory reliability.     

Cost‐effectiveness of online teacher training

This study aims to compare the cost‐effectiveness of an online teacher training method with a face‐to‐face training method in teaching ‘ICT integration in the school curriculum’. In addition, the study explores the possibilities of a school‐based voluntary training method in supporting other approaches to ICT teacher training. The analyses of various quantitative and qualitative data showed that online teacher training was more cost‐effective than face‐to‐face teacher training, mainly due to the lower opportunity cost of the participants. The voluntary teacher training revealed the possibility of providing cost‐effective training, especially in the actual application of ICT in classrooms. Based on the results of the study, factors affecting cost‐effectiveness of the teacher training approaches are discussed and further research areas suggested.     

Measurement of single leukemia cell's density and mass using optically induced electric field in a microfluidics chip

We present a method capable of rapidly (∼20 s) determining the density and mass of a single leukemic cell using an optically induced electrokinetics (OEK) platform. Our team had reported recently on a technique that combines sedimentation theory, computer vision, and micro particle manipulation techniques on an OEK microfluidic platform to determine the mass and density of micron-scale entities in a fluidic medium; the mass and density of yeast cells were accurately determined in that prior work. In the work reported in this paper, we further refined the technique by performing significantly more experiments to determine a universal correction factor to Stokes'' equation in expressing the drag force on a microparticle as it falls towards an infinite plane. Specifically, a theoretical model for micron-sized spheres settling towards an infinite plane in a microfluidic environment is presented, and which was validated experimentally using five different sizes of micro polystyrene beads. The same sedimentation process was applied to two kinds of leukemic cancer cells with similar sizes in an OEK platform, and their density and mass were determined accordingly. Our tests on mouse lymphocytic leukemia cells (L1210) and human leukemic cells (HL-60) have verified the practical viability of this method. Potentially, this new method provides a new way of measuring the volume, density, and mass of a single cell in an accurate, selective, and repeatable manner.
