Higher Education Student Engagement Scale (HESES): Development and Psychometric Evidence

Research in Higher Education - This study describes the development and validation of the Higher Education Student Engagement Scale (HESES). The psychometric evaluations of the scale included: (i)...     

Declarative knowledge acquisition in immersive virtual learning environments

The author investigated the interaction effect of immersive virtual reality (VR) in the classroom. The objective of the project was to develop and provide a low-cost, scalable, and portable VR system containing purposely designed and developed immersive virtual learning environments for the US Army. The purpose of the mixed design experiment was to compare lecture-based and immersive VR-based multimedia instruction, in terms of declarative knowledge acquisition (i.e. learning) of basic corrosion prevention and control with military personnel. Participants were randomly assigned to the control group (N?=?115) or investigational group (N?=?25) and tested immediately before and after training. The author accessed learning outcomes from the pre-exam and post-exam scores and VR system usability from exit questionnaires. Results indicate that both forms of instruction will increase learning. VR-based did produce higher gain scores and there was a statistically significant interaction between instruction type and time.     

Assessment of step accuracy using the Consumer Technology Association standard

The purpose of this study was to compare the accuracy of commercially-available physical activity devices when walking and running at various treadmill speeds using CTA 2056: Physical Activity Monitoring for Fitness Wearables: Step Counting, standard by the Consumer Technology Association (CTA). Twenty participants (10 males and 10 females) completed self-paced walking and running protocols on the treadmill for five minutes each. Eight devices (Apple iWatch series 1, Fitbit Surge, Garmin 235, Moto 360, Polar A360, Suunto Spartan Sport, Suunto Spartan Trainer, and TomTom Spark 3) were tested two at a time, one per wrist. Manual step counts were obtained from video to serve as the benchmark. The mean absolute percent error (MAPE) was calculated during walking and running. During walking, three devices: Fitbit Surge (11.20%), Suunto Sport (22.93%), and TomTom (10.11%) and during running, one device, Polar (10.66%), exceeded the CTA suggestion of a MAPE < 10%. The Moto 360 had the lowest MAPE of all devices for both walking and running. The devices tested had higher step accuracy with running than walking, except for the Polar. Overall, the Apple iWatch series 1, Moto 360, Garmin, and Suunto Spartan Trainer met the CTA standard for both walking and running.     

A time-out procedure in a public school setting

This study uses time-out as the primary therapeutic intervention with a 13-year-old highly aggressive male in a public school setting. Specific behaviors were listed prior to beginning TO and were explained to the child and teachers. TO was used over a 10-week period with extinction of the specified behaviors occurring after the seventh week. During an 8-week follow-up only three instances of the aggressive behaviors were observed. During the third and fourth weeks of TO the child began to show spontaneous interest in school work. Statistical analysis by an interrupted time-series program revealed a t (102) = - 8.290 (p <.0005) for change in level between baseline observations with intervention and follow-up data. It is concluded that TO is a sufficiently intense aversive event of itself to alter some types of deviant behavior without direct application of positive reinforcers. It is most propitiously used when alternative response modes are made available for the child.

Reading retardation or linguistic deficit? II: test-answering strategies in hearing and hearing-impaired school children

The reading test performances of 60 hearing and 60 hearing-impaired children of similar measured reading ages on the Southgate reading test were analysed. As in an earlier study using the Brimer Wide-span test it was shown that the performances of the two groups were quite different. Deaf children tackled significantly more test items than the hearing and made significantly more errors in achieving similar reading scores. A detailed examination of both correct and incorrect answers showed that the deaf children were not simply providing answers to questions at random. Even where they produced incorrect responses they tended, as a group, to select the same answer. Unlike the hearing group, who did not converge on the same incorrect solution to difficult test items, the deaf were systematic in their choices, indicating that they were using a consistent strategy. A post hoc examination of individual test items indicated that the deaf children were selecting answers on the basis of word associations in each test item. On some items these produced a correct response, on others the same (incorrect) response. The implications of these findings are discussed to argue that reading tests based on hearing norms are of little value in the assessment of reading abilities and reading problems in hearing-impaired children.     

An Online Course to Prepare Preservice Teachers to Promote Movement Integration

Previous research has not explored the potential of distance learning to prepare preservice teachers (PCTs) for promoting children’s physical activity. The purpose of this study was to (a) examine the perceptions and experiences of PCTs, inservice classroom teachers, university instructors, and elementary students who were involved in a semester-long distance delivery course that included a service-learning (SL) component with an emphasis on classroom movement integration (MI). Using a qualitative single case study design, interviews, observations, and artifacts (e.g. PCTs’ reflections and academic work) were thematically analyzed. Findings produced three themes including student-centered approach, benefit/importance of physical activity, and connect and reflect. These themes showed that participants’ perceptions and experiences support constructivist-guided SL using a distance delivery design. This study adds to the emerging research base on school-university partnerships to support schools in the implementation of comprehensive school physical activity programming.     

2014 Code of Practice: how research evidence on the role and impact of teaching assistants can inform professional practice

In this article, the author reflects on findings from research on the role and impact of teaching assistants and experience of working as a special educational needs (SEN) officer. Research evidence suggests the reliance on teaching assistants to include pupils with Statements of SEN in mainstream settings masks a collective, though unintentional, failure of educationalists to articulate and provide schools and families of children with SEN with appropriate and pedagogically sound models of inclusive provision. In light of the forthcoming reforms to the SEN system in England, key implications for educational psychologists (EPs) are drawn out, with particular reference to their role in parent liaison during the statutory assessment process.     

Missing voices and possible dialogues: problems and possibilities for teacher education

ABSTRACT

Teacher education exists today in a context of rapid globalization, which affects the systems in which future teachers will work, the governance of teachers’ work, the students teachers will be teaching, as well as the policies, programs, curricula and students in teacher education itself. Several ideas recently have gained traction internationally and are shaping the working landscape of teaching and teacher education in many countries. This essay critically examines the circulation of what appear to be a small set of ‘core’ ideas that are influencing national and institutional policies of teacher education. I explore the emergence of new players in teacher education internationally, including individuals, corporations, and international bodies. Using policy documents, influential research studies, university program statements, and interviews, the essay provides a discursive analysis of the contradictory voices in what is becoming a global conversation of teacher education. In many ways, these ideas marginalize the voices of teachers and teacher educators. They tend to narrow the definitions of education and teaching. As a counterpoint to these widely circulating arguments, I explore how reciprocal teacher education exchange programs in China and the US create opportunities for alternative constructions of visions of teaching and teacher learning.
