Design-Based Research Within the Constraints of Practice: AlgebraByExample

Superintendents from districts in the Minority Student Achievement Network (MSAN) challenged the Strategic Education Research Partnership (SERP) to identify an approach to narrowing the minority student achievement gap in Algebra 1 without isolating minority students for intervention. SERP partnered with 8 MSAN districts and researchers from 3 universities to design and rigorously test AlgebraByExample, a set of 42 Algebra 1 assignments with interleaved worked examples that target common misconceptions and errors. In a year-long random-assignment study, students who received AlgebraByExample assignments had an average 7 percentage point boost on a posttest containing released items from state assessments, and students in the bottom half of the performance distribution where minority students are disproportionately concentrated had an average 10 percentage point boost on a researcher-designed assessment of conceptual understanding. AlgebraByExample is easily incorporated into any existing curriculum, and naturally serves as a launch point for mathematically rich discussion.     

Programme recruitment and evaluation: the effect of an employability enhancement programme on the general self-efficacy levels of unemployed graduates

This paper reports research that engaged in the evaluation of an intervention programme designed to enhance the employability of a group of unemployed graduates. The evaluation adopted a quasi-experimental intervention research method employing a general self-efficacy scale, which had been validated in prior research. Results revealed that participants displayed higher levels of GSE after engagement in the programme. Results also revealed the effect of ‘behavioural plasticity’ on the intervention experiences of unemployed graduate participants. The findings of this study are discussed in relation to programme design, recruitment and evaluation.     

Governing for Results on a Postcollective Bargaining Wisconsin School Board

The popular narrative of Wisconsin’s collective bargaining battle started out being about money. Should public employees pay more toward their healthcare? Can school districts offset state aid cuts using the additional revenue from employee healthcare contributions? Does collective bargaining have a cost? This article gives an overview of Wisconsin school boards, explains exactly how Act 10 increased their power, demonstrates why and how improved school board governance can have an impact on student achievement, reviews the changes Wisconsin school boards are making because of Act 10, and provides policy recommendations to improve both board governance behaviors, and the quality of policies enacted by school boards in the postcollective bargaining era.     

Infant vocalizing and phenotypic outcomes in autism: Evidence from the first 2 years

Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White; collected from 2007 to 2017 near Philadelphia) were analyzed at 6, 12, and 24 months. At 12 months, HR-ASD infants produced fewer vocalizations than HR-Neg infants. From 6 to 24 months, HR-Neg infants demonstrated steeper vocalization growth compared to HR-ASD and LR infants. Finally, among HR infants, vocalizing at 12 months was associated with language, social phenotype, and diagnosis at age 2. Infant vocalizing is an objective behavioral marker that could facilitate earlier detection of ASD.
