Bridging research and practice: challenges and successes in implementing evidence-based preventive intervention strategies for child maltreatment

Child maltreatment has been associated with a wide range of negative developmental outcomes for children and families as well as significant economic consequences. While efficacious intervention strategies have been demonstrated to reduce symptoms of trauma and to improve behavioral and emotional functioning, these models have not been widely adopted by clinicians. The challenges associated with exporting evidence-based interventions into community settings are discussed, along with an example of a preventive intervention program for young mothers, successfully implemented through a partnership of community agencies and funders.     

The effect of an informal science intervention on middle school girls’ science affinities

This study investigates the impact of an informal science outreach programme built around theories of identity formation and self-efficacy on middle school girls’ science affinities. A lottery-based, randomised control trial was used to identify programme effects on four science affinity outcomes: science interests, efficacy with science, science attitudes, and science identity. A multivariate analysis of variance demonstrated that programme participants scored higher than their control group peers on weighted composite of post-programme affinity indicators. These results suggest that informal science education may offer a venue through which to support the formation of science identities and efficacy in girls. Implications for including psychosocial support elements into science classroom pedagogy and science education standards are discussed.     

The Influence of Teachers’ Efficacy and Beliefs Regarding Mathematics Instruction in the Early Childhood Classroom

This was a correlational study conducted with a population of prekindergarten educators from a large, metropolitan school district. The purpose was to examine if there were relationships between and among early childhood teachers’ sense of self-efficacy, their beliefs about the importance of mathematics, and their mathematics instructional practices. Examining teachers’ efficacy and beliefs can inform educational practice and help to differentiate between more and less successful instructional practices when teaching mathematics in the early childhood classroom. Data were collected on teacher efficacy and teacher beliefs about the importance of mathematics with two self-report questionnaires. The hypothesis that the teachers higher in efficacy will rate the importance of mathematics higher on the teacher-belief scale than the teachers with lower efficacy was found to be true with this sample, but the correlation was weak. The level of efficacy of the early childhood teachers in this sample confirmed that in assessing their capabilities, they rate themselves high in instructional strategies, classroom management, and student engagement. The early childhood teachers did not rate their belief in mathematics as high as their efficacy. Observations of mathematics instructional practices were conducted with twenty teachers. It was hypothesized that the combination of high teacher efficacy and high teacher mathematics beliefs would show alignment with the presence of standards-based mathematics instructional practices. The results were not statistically significant. No correlation signals a need for more research to explore what other personal or external factors relate to mathematics instructional practices in the early childhood classroom. The research may inform pre kindergarten teachers and teacher educators about effective instructional strategies and knowledge needed to launch early childhood students on a developmentally appropriate pathway to mathematical literacy.     

Using the Science Writing Heuristic to Improve Undergraduate Writing in Biology

Our objective was to investigate the impact of the Science Writing Heuristic (SWH) on undergraduates’ ability to express logical conclusions and include appropriate evidence in formal writing assignments. Students in three laboratory sections were randomly allocated to the SWH treatment (n?=?51 students) with another three sections serving as a control (n?=?47 students). All sections received an identical formal writing assignment to report results of laboratory activities. Four blinded raters used a 6-point rating scheme to evaluate the quality of students’ writing performance. Raters’ independent scoring agreement was evaluated using Cronbach's α. Paper scores were compared using a t-test, then papers were combined into low-scoring (3.5 of 6 points) or high-scoring (>3.5 of 6 points) sets and SWH and control cohorts were compared using Pearson's chi-square test. Papers from the SWH cohort were significantly (P?=?0.02) more likely to receive a high score than those from the control cohort. Overall scores of SWH cohort papers tended to be higher (P?=?0.07) than those from the control cohort. Gains in student conceptual understanding elicited by the SWH approach improved student ability to express logical conclusions about their data and include appropriate evidence to support those conclusions in formal research reports. Extending the writing tasks of the SWH to formal writing assignments can improve the ability of undergraduates to argue effectively for their research findings.     

Consultants and Coteachers Affecting Student Outcomes with Numbered Heads Together: Keeping All Engaged

General education teachers, special education teachers, social workers, psychologists, and a myriad of specialists are responsible for delivering content to all students within inclusive environments. These educational teams continue to search for strategies that can be recommended or used in an inclusive environment. Researchers have discovered that an instructional strategy such as Numbered Heads Together (NHT) increases both academic and behavioral outcomes for students with and without disabilities. This article provides consultants, Response to Intervention (RtI) team members, and coteaching teams with a specific strategy of NHT that can be used by two or more professionals to develop lessons or deliver instruction using a coteaching or consultant approach with both professionals (consultant and general education teacher) assessing learner outcomes after the completion of the activity.     

Educational Support for Saudi Students with Learning Disabilities in Higher Education

Disability laws in Saudi Arabia mandate that higher education institutions provide support for special needs learners in order to ensure educational opportunities equivalent to opportunities for their nondisabled peers. These institutions experience challenges, however, in providing the necessary support to undergraduate and postgraduate students with learning disabilities (LDs). We conducted an exploratory study to assess educational support requirements and affordances for undergraduate and postgraduate students with LDs attending institutions of higher education in Saudi Arabia. We completed semistructured interviews with 22 special needs learners diagnosed with a LD (16 undergraduate and six postgraduate). The findings suggest that additional support services are needed for undergraduate and postgraduate students with LDs attending Saudi institutions of higher education.     

Customer participation and new product performance: Towards the understanding of the mechanisms and key contingencies

In a study of 243 firms of varying sizes across 14 different industries, we investigate the effect of customer participation on new product development performance. We confirm that overall customer participation is positively related to new product development performance and that the effect is mediated by innovativeness. We also demonstrate that these effects are contingent upon absorptive capacity of the firm in question such that firms with high absorptive capacity stand to gain more from engaging their customers in new product development than firms with low absorptive capacity, especially at the later stages of the NPD process. The results are robust to alternative estimation techniques, measures employed to operationalize key concepts, and the industrial makeup of the sample. Post hoc analyses provide non-trivial managerial implications for the decision makers at the firm level.     

Potentiation of responding on a VR schedule by a stimulus correlated with reinforcement: Effects of diffuse and localized signals

In Experiment 1, rats were trained to leverpress on a variable ratio (VR) 30 schedule with a 500-msec delay between the reinforced response and food delivery. Subjects that experienced a signal during the delay responded faster than did control subjects that received the stimulus un-correlated with reinforcement. Higher response rates were obtained when the stimulus used to signal reinforcement was auditory rather than visual. Experiments 2 and 3 compared the effects of signaling reinforcement with either a localized or a diffuse light on responding maintained by VR schedules of reinforcement. Elevated response rates were observed with the diffuse stimulus, but the localized stimulus failed to produce such potentiation. Experiment 3 also examined the conditioned reinforcing power of localized and diffuse visual stimuli. These results are discussed with reference to (1) theories of selective association and sign tracking and (2) their implications for current theories of signaling reinforcement.
