Development of the Beliefs about Primary Education Scale: Distinguishing a developmental and transmissive dimension

In this article the development and validation of the Beliefs about Primary Education Scale (BPES) are described. The BPES is an 18-item scale for assessing primary school teachers’ beliefs toward the nature of good education, subdivided in a transmissive dimension (TD) and a developmental dimension (DD). Both dimensions assess beliefs toward the general orientation and objectives of education, the nature of the educational content, and desirable ways of knowledge acquisition. An explorative study (n=352$n=352$) revealed a two-factor structure. Both dimensions were uncorrelated, which leads to the suggestion that teachers hold layered belief systems. In a following study (n=381), construct validity of the BPES was confirmed. The BPES’ DD and TD were shown to correlate significantly with constructivist and traditional teaching beliefs.     

Longitudinal research on beginning teacher development: Complexity as a challenge to concerns-based stage theory

Stage theory represents a concise explanation for change in teacher professional development with gained experience in the classroom. This study examines the self-task-impact   stage chronology proposed by concerns-based theory within the framework of longitudinal research on beginning teaching. The study investigated developmental change in a panel (N=79$N=79$) of beginning teachers across two years utilizing the Teacher Concerns Checklist, a concerns inventory, at six application points. Analysis of variance with Scheffé post hoc tests was utilized to rank categories of concerns and to test whether teacher and school contextual variables would affect these rankings. The results confirm findings of similar longitudinal studies, indicating teachers’ concerns for impact consistently rank highest across time. Additionally, the ranking of concerns categories was not affected by the contextual variables. Two aspects of impact, one academic in orientation and the second consisting of personal and individual concerns for students, emerged as distinct dimensions across time. The author proposes a reconsideration of concerns-based theory for its limited ability to comprehensively explain the complex nature of teacher development. Rather than chronological, concerns are recurring and indicate the need to scaffold linkages between student learning, learning theory, and instructional practices early in teaching careers in lieu of singularly focused managerial aspects of teaching.     

Performance of the S[... formula ...]2 Statistic for the Multidimensional Graded Response Model

S−χ2 is a popular item fit index that is available in commercial software packages such as flexMIRT. However, no research has systematically examined the performance of S−χ2 for detecting item misfit within the context of the multidimensional graded response model (MGRM). The primary goal of this study was to evaluate the performance of S−χ2 under two practical misfit scenarios: first, all items are misfitting due to model misspecification, and second, a small subset of items violate the underlying assumptions of the MGRM. Simulation studies showed that caution should be exercised when reporting item fit results of polytomous items using S−χ2 within the context of the MGRM, because of its inflated false positive rates (FPRs), especially with a small sample size and a long test. S−χ2 performed well when detecting overall model misfit as well as item misfit for a small subset of items when the ordinality assumption was violated. However, under a number of conditions of model misspecification or items violating the homogeneous discrimination assumption, even though true positive rates (TPRs) of S−χ2 were high when a small sample size was coupled with a long test, the inflated FPRs were generally directly related to increasing TPRs. There was also a suggestion that performance of S−χ2 was affected by the magnitude of misfit within an item. There was no evidence that FPRs for fitting items were exacerbated by the presence of a small percentage of misfitting items among them.     

The impact of shared book reading on children's language skills: A meta-analysis

Shared book reading is thought to have a positive impact on young children's language development, with shared reading interventions often run in an attempt to boost children's language skills. However, despite the volume of research in this area, a number of issues remain outstanding. The current meta-analysis explored whether shared reading interventions are equally effective (a) across a range of study designs; (b) across a range of different outcome variables; and (c) for children from different SES groups. It also explored the potentially moderating effects of intervention duration, child age, use of dialogic reading techniques, person delivering the intervention and mode of intervention delivery.Our results show that, while there is an effect of shared reading on language development, this effect is smaller than reported in previous meta-analyses ($\bar{g}$ = 0.194, p = .002). They also show that this effect is moderated by the type of control group used and is negligible in studies with active control groups ($\bar{g}$ = 0.028, p = .703). Finally, they show no significant effects of differences in outcome variable (ps ≥ .286), socio-economic status (p = .658), or any of our other potential moderators (ps ≥ .077), and non-significant effects for studies with follow-ups ($\bar{g}$ = 0.139, p = .200). On the basis of these results, we make a number of recommendations for researchers and educators about the design and implementation of future shared reading interventions.
