Effects of Collective Efficacy,Teamwork Attitudes,and Experience on Group Project Performance: Comparisons Between 2 Food Science Courses

The relationship between past teamwork and task‐related experiences, attitude toward teamwork, collective efficacy, and task performance among undergraduates (N = 298) assigned to group projects (N = 48) in 2 different Food Science courses was examined. The results of survey data collected at the beginning and end of the projects showed that past teamwork and task‐related experience predicted individual student efficacy at the end of the project, and that starting efficacy, but not attitudes toward teamwork, mediated that relationship. Convergence over time among team members’ efficacy, and diversity of past task‐related experiences was positively related to project grade, whereas diversity in past teamwork experiences was negatively related to project grade. The relationship between past experiences, attitude toward teamwork, efficacy, and grades did not differ between the 2 courses. Implications for practices of implementing group class projects are discussed.     

Innovation and network multiplexity: R&D and the concurrent effects of two collaboration networks in an emerging economy

This study focuses on the multiplexity of firm R&D networks, and it investigates two types of boundary-spanning networks: the bipartite network between firms and government-sponsored institutions (GSIs), and the traditional firm–firm network. We apply a social network perspective to examine the effects that these kinds of networks have on firm innovativeness, in relation to the effects of the firm’s internal R&D efforts. We define the firm-GSI network as bipartite, and we investigate how the structural characteristics of this network (cohesion and centrality) affect innovativeness. We then decompose the innovational effects of firm–firm networks into two categories (intra- and inter-sector) to distinguish the effects of these collaboration networks. Furthermore, we investigate how these various external collaborative networks interact with a firm’s internal R&D efforts for driving innovativeness. Our empirical study of 420 manufacturing firms in Mexico evaluates evidence from surveys and secondary data. The findings indicate that the structural properties of both firm–GSI and firm–firm networks have positive effects on innovativeness, but firm–GSI network cohesion has a stronger negative interaction with R&D in influencing firm innovativeness. Moreover, intra-sector centrality in a firm–firm network has a stronger negative interaction with R&D than inter-sector centrality does in driving firm innovativeness. We contribute to the literature by integrating insights from the perspectives of network multiplexity, social embeddedness, and resource complementarity in regard to inter-organizational behavior. Our study also provides meaningful guidelines for both managers and policy makers. The study’s findings are robust to concerns of common method bias and alternative model specifications.

Longitudinal literacy professional development in an urban elementary charter school

The authors describe a school-university professional development partnership in a high-needs urban elementary charter school. University and school partners collaborated to build instructional capacity to develop teachers’ understanding and implementation of effective literacy instruction. Design-based research revealed increased understanding and implementation of effective literacy practices among school leaders and teachers. Findings revealed the importance of administrative stability; coaching support; and a focused, school-wide instructional vision.     

Principals’ Instructional Leadership Within a Teacher Performance Appraisal System: Enhancing Students’ Academic Success

The purpose of this study was to identify principals’ instructional leadership actions within a comprehensive teacher evaluation system in successful schools rated as recognized or exemplary by the accountability measures in place. The study followed a multiple case study approach. Participants included six school administrators within the same school district. From these three were principals and three assistant principals, representing all three schools levels—elementary school, middle school, and high school. The main data sources consisted of interviews, observations and journaling. Data were analyzed inductively to discern emerging themes. Findings of the study revealed that principals’ instructional leadership actions at all three levels included setting clear expectations, monitoring instruction through walk-through observations, and providing professional development opportunities according teachers’ needs. Furthermore, the cross site analysis revealed that principals tend to rely on instructional leadership actions that are pertinent to each grade level’s needs. Findings also suggest that principals, indeed, apply the teacher performance appraisal system as a basis to enhance instruction and improve student achievement.     

ISPCAN Child Abuse Screening Tool Children's Version (ICAST-C): Instrument development and multi-national pilot testing

ObjectiveTo develop a child victimization survey among a diverse group of child protection experts and examine the performance of the instrument through a set of international pilot studies.MethodsThe initial draft of the instrument was developed after input from scientists and practitioners representing 40 countries. Volunteers from the larger group of scientists participating in the Delphi review of the ICAST P and R reviewed the ICAST C by email in 2 rounds resulting in a final instrument. The ICAST C was then translated and back translated into six languages and field tested in four countries using a convenience sample of 571 children 12–17 years of age selected from schools and classrooms to which the investigators had easy access.ResultsThe final ICAST C Home has 38 items and the ICAST C Institution has 44 items. These items serve as screeners and positive endorsements are followed by queries for frequency and perpetrator. Half of respondents were boys (49%). Endorsement for various forms of victimization ranged from 0 to 51%. Many children report violence exposure (51%), physical victimization (55%), psychological victimization (66%), sexual victimization (18%), and neglect in their homes (37%) in the last year. High rates of physical victimization (57%), psychological victimization (59%), and sexual victimization (22%) were also reported in schools in the last year. Internal consistency was moderate to high (alpha between .685 and .855) and missing data low (less than 1.5% for all but one item).ConclusionsIn pilot testing, the ICAST C identifies high rates of child victimization in all domains. Rates of missing data are low, and internal consistency is moderate to high. Pilot testing demonstrated the feasibility of using child self-report as one strategy to assess child victimization.Practice implicationsThe ICAST C is a multi-national, multi-lingual, consensus-based survey instrument. It is available in six languages for international research to estimate child victimization. Assessing the prevalence of child victimization is critical in understanding the scope of the problem, setting national and local priorities, and garnering support for program and policy development aimed at child protection.     

Trading quality across borders: colonial discourse and international quality assurance policies in higher education

Accountability and quality assurance have become central discourses in higher education policy throughout the world. However, accountability and quality assurance involve power and control. Practices and ideas about quality developed in the Global North are spreading rapidly across the Global South, leading to increased uniformity in the approaches to quality assurance. Given the significant asymmetries that divide the Global North and Global South, this article maps interdiscursive relations among key texts that influence policy development on international quality in higher education, and explores the applicability of colonial discourse as a perspective for understanding this increasing international convergence.
