A Comparison of Linking Methods for Estimating National Trends in International Comparative Large‐Scale Assessments in the Presence of Cross‐National DIF

Trend estimation in international comparative large‐scale assessments relies on measurement invariance between countries. However, cross‐national differential item functioning (DIF) has been repeatedly documented. We ran a simulation study using national item parameters, which required trends to be computed separately for each country, to compare trend estimation performances to two linking methods employing international item parameters across several conditions. The trend estimates based on the national item parameters were more accurate than the trend estimates based on the international item parameters when cross‐national DIF was present. Moreover, the use of fixed common item parameter calibrations led to biased trend estimates. The detection and elimination of DIF can reduce this bias but is also likely to increase the total error.     

Evaluating a Multidimensional Reading Comprehension Program and Reconsidering the Lowly Reputation of Tests of Near‐Transfer

We conducted a 14‐week experimental study of 2 versions of a relatively comprehensive RC intervention that involved 50 classroom teachers, 15 tutors, and 116 children drawn in equal proportions from grades 3 and 5 in 13 schools in a large urban school district. Students were randomly assigned in equal numbers to the two tutoring conditions and a control group. Results indicated that students in the two tutored groups tended to perform comparably on all tests and to outperform controls (more so in grade 5 than grade 3) on near‐transfer but not far‐transfer measures of RC. This differential pattern of program effects for near‐ versus far‐transfer measures raises questions about how tests of near‐transfer and far‐transfer are conventionally understood.     

Collaborative learning processes in the context of a public health professional development program: a case study

The health promotion laboratory (HPL – Canada) is a public health professional development program building on a collaborative learning approach in order to support long-term practice change in local health services teams. This study aims to analyse the collaborative learning processes of two teams involved in the program during the first year of implementation. Based on a multiple case study design involving observations, interviews, and documentary sources, the study: (1) describes the learning process by which each team built a common understanding of the problem at hand and developed an intervention to address it; (2) identifies factors that facilitated or hindered these processes; and (3) proposes a cross-case explanation of the collaborative learning process in the HPL. The results demonstrate that the two teams learned by expanding their repertoire of actions, albeit experiencing different processes. Results point to the central role of shared mental models and key influencing factors, such as commitment and participation (team cohesion), team climate (psychological safety), and leadership style. Unlike previous studies on team learning that concentrated on existing teams in organisations, the current research studied purposely created teams working at transforming their practices and showed that they can successfully learn if specific conditions are achieved.     

Assessing the Effectiveness of a College Freshman Seminar Using Propensity Score Adjustments

Researchers investigated the impact that a first-year college experience course had on students?? first-year grade point averages (GPAs) and retention rates. A sample of 109 first-year students enrolled in the course was compared to a sample of 326 students from the same university who had not taken the course. The goals of the experience course were to reduce attrition, increase grade point averages, and enhance academic skills. Without accounting for selection bias, those who took the course had similar retention rates and lower GPAs than those who did not take the course. After matching on propensity scores, the negative effects of the program on GPA were nullified and those in the program were more likely to enroll for a second year. Although the benefits from the course were weak, the positive impact of the program was more apparent after accounting for individual differences.     

Sibling Adjustment and Maternal Well-Being: An Examination of Families With and Without a Child With an Autism Spectrum Disorder

Differences in sibling social, behavioral, and academic adjustment and maternal well-being in families with (n = 20) and without (n = 23) a preschooler with autism spectrum disorder (ASD) were explored. Results are interpreted to suggest that mothers of children with autism report more daily hassles, life stress, and depression than mothers without a child with ASD. There were no significant differences in parent and teacher reports of older siblings' social, behavioral, and academic adjustment in families with and without a child with ASD. Sibling behavioral adjustment was, however, significantly related to maternal well-being. Because families with children with ASD often experience more parenting stress and depression, siblings may be more vulnerable to the cumulative risks over time.
