Developing communication as a graduate outcome: using ‘Writing Across the Curriculum’ as a whole-of-institution approach to curriculum and pedagogy

Communication is widely recognised as an important capability for university graduates [Organisation for Economic Co-operation and Development. (2013). OECD skills outlook 2013: First results from the survey of adult skills. Author. Retrieved from http://dx.doi.org/10.1787/9789264204256-en]. Yet, research suggests that it is often not adequately developed by Australian universities, remaining implicit in teaching and assessment. This is in part because Australian universities have historically conceptualised communication not as an outcome of disciplinary study, but as a generic, foundational competency or skill. It has therefore been managed outside the curriculum by establishing academic language and learning units that help students develop written and spoken communication through a range of student services. The services model of communication development is becoming untenable, however, given the increasing cultural and linguistic diversity of students and the recognised importance of communication as a graduate outcome. Whole-of-institution approaches are required to integrate communication into course curricula as a fundamental part of disciplinary learning, and develop the capacity of teaching staff to teach it. This paper explores Writing Across the Curriculum and Writing Inside the Disciplines, two complementary approaches used widely in the US for developing literacy in higher education. They emerged in the 1970s in response to the kind of student diversity now common in Australian universities, and offer institution-wide strategies for developing communication as an essential outcome of study in academic and professional disciplines.     

The Impact and Interpretation of Modeling Residual Noninvariance in Growth Mixture Models

Current practices for growth mixture modeling emphasize the importance of the proper parameterization and number of classes, but the impact of these decisions on latent class composition and the substantive implications has not been thoroughly addressed. Using measures of behavior from 575 middle school students, we compared the results of several multilevel growth mixture models. Results indicated a dramatic shift in class assignment as the models allowed class-varying parameters, with different substantive interpretations and resulting typologies. This research suggests that using variability as a criterion for class differences in a behavior typology can dramatically impact latent class membership. This study describes decisions and results from testing for noninvariance, with particular emphasis on how decisions about the nature of within-person variance can affect resulting subgroups and model parameters.     

An Investigation of the Alignment Method With Polytomous Indicators Under Conditions of Partial Measurement Invariance

The alignment method (Asparouhov & Muthén, 2014) is an alternative to multiple-group factor analysis for estimating measurement models and testing for measurement invariance across groups. Simulation studies evaluating the performance of the alignment for estimating measurement models across groups show promising results for continuous indicators. This simulation study builds on previous research by investigating the performance of the alignment method’s measurement models estimates with polytomous indicators under conditions of systematically increasing, partial measurement invariance. We also present an evaluation of the testing procedure, which has not been the focus of previous simulation studies. Results indicate that the alignment adequately recovers parameter estimates under small and moderate amounts of noninvariance, with issues only arising in extreme conditions. In addition, the statistical tests of invariance were fairly conservative, and had less power for items with more extreme skew. We include recommendations for using the alignment method based on these results.     

Success at Scale: Outcomes of Community-Based Neurodevelopment Intervention (CASITA) for Children Ages 6–20 months With Risk of Delay in Lima,Peru

This study is a randomized controlled trial of a 12-week community-based group parenting intervention (“CASITA”) in Lima, Peru. CASITA improved neurodevelopment in a pilot study of 60 Peruvian children and subsequently scaled to 3,000 households throughout the district. The objective of this study was to assess intervention effectiveness when implemented at scale. A total of 347 children ages 6–20 months (52.7% male, 100% identified as “mestizo”) at risk for developmental difficulties were randomized to immediate or delayed CASITA. At 3 months after enrollment, the immediate arm showed significantly higher overall development, based on the Extended Ages and Stages Questionnaire and Home Observation for Measurement of the Environment scores (Cohen’s ds = .36 and .31, respectively). Programs demonstrably effective at scale could help address children’s development risks worldwide.
