An exploratory study on collaborative modes of professional development and learning for teachers of students with autism spectrum disorder (ASD)

This study aims to deliver a school‐based mode of training for in‐service teachers of students with ASD in Hong Kong. The training is delivered following the phases of implementation science, namely, exploration, installation, and implementation. The project team used the theory of mind approach, which enables teachers to engage with students with ASD and to focus on recognizing and reacting to emotions. Participants in this study included four educators from a teacher education institution, three expert teachers, and 19 in‐service teacher trainees. The most salient responses came from trainees who were provided with the opportunity to apply learned skills in their own classrooms immediately and to share the knowledge and skills in dealing with students with ASD in the post‐conference meetings.     

Improving teaching self-efficacy for teachers in inclusive classrooms in Hong Kong

This study investigated changes in teacher self-efficacy for inclusive practice using a mixed method research design. Participants were 417 in-service teachers in Hong Kong taking a 1-week basic teacher-training course about inclusive education. Data were collected pre and post participation in the course using the Teacher Efficacy for Inclusive Practices Scale (TEIP). A series of five in-depth focus-group interviews provided greater clarification of the perceptions and efficacy issues of teachers. The best predictors to participants’ teaching self-efficacy were confidence in teaching students with special education needs (SEN) and knowledge of legislation and policies for inclusive practice. From the focus-groups, results demonstrated a more positive attitude change towards students with SEN with a number of essential factors emerging as highly beneficial for inclusive teaching in Hong Kong (i.e. caring and love, school environment and curriculum adaption). The discussion considers the role of short training programmes as an appropriate means to improving self-efficacy for teaching within inclusive classrooms in Hong Kong.     

Pedagogy * technology: A two‐dimensional model for teachers' ICT integration

This paper presents a two‐dimensional model for measuring individual teachers' progression in ICT integration and for guiding them toward higher integration levels. There are four levels in the pedagogy dimension: direct teaching, cognitively active learning, constructive learning, and social learning. These levels are defined based on four factors: teacher pedagogical beliefs, instructional strategies used, teacher‐student interactions, and the types of tasks students are expected to carry out. The technology dimension contains eight levels, ranging from Level 0 (nonuse) to Level 7 (implementing sophisticated instructional applications). The eight levels are defined based on three factors: whether a teacher is a passive consumer or an active producer of the ICT‐based resources, sophistication of the ICT tools that a teacher uses, and richness of functionality of an ICT‐based product developed by a teacher. To validate the proposed model in terms of its applicability and practicability, three case studies were conducted. The results showed that this model was able to adapt to individual preferences of the three participating teachers as well as guide their progressions in ICT integration.

The Reported Effects of a Systematic Professional Learning Program on the Knowledge,Skills, and Concerns of Australian Early Childhood Educators who Support Young Children Displaying or at Risk of Challenging Behaviours

High-quality early childhood education is a vital experience for young children with and without disabilities. Social and communication experiences in the context of play represent a core curriculum that sets a foundation for later learning and participation. Using a new self-report instrument, this article describes data collected in a large-scale professional learning project in NSW, Australia, that aimed to support early childhood teachers, paraprofessionals and other personnel who directly work with young children, including individuals who present or are at risk of challenging behaviours. Using a case application model of remote and direct coaching support and intervention centred on the input of expert practitioners, the reports of participants were collected before and after a series of three sequential workshops with embedded action research processes for participants. The program was designed to increase social and communicative exchanges and reduce the likelihood of challenging behaviours, by providing a systematic and practical framework for the introduction of functional behavioural assessment and positive support planning. Respondents indicated significant improvements in knowledge and skills after the program, along with decreased concerns in some areas. The paper concludes by discussing potential areas for an expanded research agenda into the professional learning needs of personnel in this field and more broadly within early childhood support systems and services.     

Comparison of the Criterion-Related Validity of Sit-and-Reach Tests with and without Limb Length Adjustment in Asian Adults

Abstract

The stages of motivational readiness as conceptualized by the Transtheoretical Model have been widely used among adult samples to assess readiness for adopting exercise behavior. To date, little research has been conducted using a staging framework with adolescent samples. There is a need for validation of the staging framework prior to a substantial amount of research with this age group. The current article presents two studies assessing stage and reported exercise behavior (Study 1: n = 819; M age = 15.0 years, SD = 1.2; 51 % men; Study 2: n = 184; M age = 18.6 years, SD = .5; 45 % men). As hypothesized in both studies, reported exercise consistently varied as a function of stage classification; those in earlier stages of readiness reported less exercise than those in later stages. Staging algorithms showed good sensitivity to detect reported exercise; however, specificity was distinctly better with the algorithm that used a specific activity criterion and immediate intention, as opposed to irregular behavior, in defining the preparation stage. Results support the validity of the staging framework for measuring motivational readiness for exercise behavior among North American adolescents.
