Measuring conflict management,emotional self-efficacy,and problem solving confidence in an evaluation of outdoor programs for inner-city youth in Baltimore,Maryland

Substantial evidence supports the value of outdoor education programs for promoting healthy adolescent development, yet measurement of program outcomes often lacks rigor. Accurately assessing the impacts of programs that seek to promote positive youth development is critical for determining whether youth are benefitting as intended, identifying best practices and areas for improvement, and informing decisions about which programs to invest in.We generated brief, customized instruments for measuring three outcomes among youth participants in Baltimore City Outward Bound programs: conflict management, emotional self-efficacy, and problem solving confidence. Measures were validated through exploratory and confirmatory factor analyses of pilot-testing data from two groups of program participants. We describe our process of identifying outcomes for measurement, developing and adapting measurement instruments, and validating these instruments.The finalized measures support evaluations of outdoor education programs serving urban adolescent youth. Such evaluations enhance accountability by determining if youth are benefiting from programs as intended, and strengthen the case for investment in programs with demonstrated success.

Mothers' work patterns and Children's cognitive achievement: Evidence from the India Human Development survey

As female labor force participation increases globally, the relationship between maternal employment and children's development remains unclear. Using data from the India Human Development Survey (2005), we investigate the link between maternal employment and children's arithmetic and reading achievement. We develop a work pattern typology that goes beyond standard measures of employment and captures work intensity and its compatibility with child-rearing in a transitional economy. We find that the relationship between maternal employment and children's outcomes is not unidimensional. For example, children of self-employed mothers are not disadvantaged compared to those with stay-at-home mothers, but maternal employment in salaried jobs or wage work outside the home is negatively associated with cognitive skills in children. However, this negative association is reversed at higher levels of maternal education, suggesting greater access to resources and flexibility associated with better jobs mitigate the negative aspects of maternal employment posed by time constraints. Additionally, maternal employment is associated with maternal involvement in schoolwork and financial investment in academic activities, providing evidence that both time and resources devoted to children's education are significant.

Impact of an Overt Response System on Staff Performance and Maintenance of Computer-Based Instruction

Interactive Computer Based Instruction (CBI) systems involve teaching strategies to facilitate greater response opportunities during training in an effort to improve learner performance. The current study investigated the effect of online staff training videos with and without overt response requirements on posttest and maintenance test scores across six block-randomized instructional modules for four employees of a university located in the southeastern region of the United States. The overt response consisted of multiple-choice questions administered throughout select teaching modules using an alternating treatment design. Findings suggest that learning occurred as a result of the CBI training; however, the effectiveness of the overt response system varied across individuals, with no discernible differentiation between learning gains associated with response requirements. Other areas of research for expanding the efficacy of CBI and overt response systems are highlighted.     

‘What you need to do is …’: social work students’ reflections on an advice giving audit exercise

This paper reports on qualitative research investigating the advice giving behaviours of social work students. Second-year students, who were enrolled in an interpersonal communication skills course, were required to undertake an ‘advice-giving audit’ exercise across 6 days, with the aim of strengthening their awareness of the interactive nature of advice giving. Students then wrote a diary entry about the frequency of their everyday advice giving behaviour, its intent and reception. Nineteen students provided these reflections for analysis. Findings included three themes pertaining to advice-giving: (i) Giving advice as a natural, comfortable and unconscious way of communicating; (ii) Power and position influences advice dissemination, and (iii) Withholding advice opens, deepens and confuses norms of communication. A fourth theme pertained to the insights that students reported from engaging with the exercise. These findings illustrate the complex interactional process associated with professional advice giving. The research also suggests that experiential activities, which are conducted outside of the classroom, have significant potential to promote the critical examination of embedded communicative practices.
