A Short Note on Interpretation in the Dual Change Score Model

The latent change score framework allows for estimating a variety of univariate trajectory models, such as the no change, linear change, exponential forms of change, as well as multivariate trajectory models that allow for coupling between two or more constructs. A particularly attractive feature of these models is that it is easy to decompose and interpret aspects of change. One particularly flexible model, the dual change score model, has two components of change: a proportional change component that depends on scores at the previous time point, and a constant change component that is additive. We demonstrate through simulation and an empirical example that in a correctly specified model, the correlation between the proportional change parameter and the mean of the constant change component can approach either ?1 or 1, thus complicating interpretation. We provide recommendations and code to aid researchers’ ability to diagnose this issue in their own data.     

Exploring strategies for online teaching and learning

This paper explores various strategies for creating engaging online learning environments. It describes a framework which identifies and distinguishes between the critical elements needed in the design of online learning: the content of the course, the learning activities and the learning supports. It demonstrates through practical examples how each of these elements can be manipulated in deliberate ways to influence learning processes and outcomes. The paper supports the notion that online courses are best when they arc engineered to take advantage of the learning opportunities afforded by the online technologies, rather than being used as supplements to conventional teaching programs.     

The adolescent motor performance development of elite female soccer players: A study of prognostic relevance for future success in adulthood using multilevel modelling

ABSTRACT

Considering the scarce empirical evidence regarding talent predictors in female youth soccer, the present study aimed to investigate the long-term prognostic validity of elite female soccer players’ adolescent motor performance for future success in adulthood. Additionally, the three-year development of highly talented girls’ motor performance and the predictive value of this motor development for reaching a professional adult performance level (APL) was analysed.

Overall, N = 737 female players participated in nationwide motor diagnostics (sprinting, agility, dribbling, ball control, shooting) within the German Soccer Association’s talent identification and development programme at least twice between the age groups Under-12 (U12) and U15. Based on their APL at least four years later, participants were assigned to a professional (first German division, 6.2%) or non-professional group (lower divisions, 93.8%).

Multilevel regression analyses revealed a general prognostic relevance for the investigated parameters with respect to players’ APL. In addition, there was a non-linear improvement in participants’ motor performance across all variables from U12 to U15. However, non-significant interactions between APL and these improvements indicate motor performance development itself cannot adequately predict players’ future success in adulthood. Findings provide insightful information that can help coaches foster optimal support for young female soccer players’ development.     

Integrating Web 2.0 Across the Curriculum

For many years, educators have touted the benefits of learning with educational tools such as spreadsheets and databases that allow students to actively process and manipulate information (Jonassen, 1995). Hundreds if not thousands of Web 2.0 tools have been created in the last few years, taking the “technology as tool” metaphor to a new level. In this article, selected Web 2.0 tools are aligned with major content areas to illustrate by example the wide reach of Web 2.0 across the curriculum.     

Effort on homework in grades 5-9: development, motivational antecedents, and the association with effort on classwork

In 2 studies, an expectancy-value framework was applied to investigate effort expended on mathematics homework. In Study 1 (2,712 students in grades 5, 7, and 9; mean age=13.37 years), lower homework effort was found in higher grades. The effects of intrinsic value on homework effort were higher in the older cohorts, whereas the effects of the expectancy component were lower. In Study 2 (571 students in grades 8 and 9; mean age=14.72), an expanded expectancy-value framework was found to explain both homework and classwork variables. The means for effort and value were lower for homework than for classwork; these differences were partly moderated by students' conscientiousness. The implications of homework behavior and motivation for developmental research are highlighted.     

Developing a service management strategy facilitated by action learning: an empirical study from the UK health & fitness industry

One of the principle tenets of action learning is that it provides the potential to explore and solve complex organisational problems. The question of how best to develop a future business strategy is such a problem. Existing literature on strategy making presents a multi-faceted debate, suggesting that the complexity of competitive environments means that the strategic route forward for many organisations can often be unclear. As a lecturer who teaches strategy at university, I have been intrigued by the ‘Learning Group’ of strategy making (Argyris & Schon, 1974; Quinn, 1980; Mintzberg, 1987; Argyris, 1993, 2004) for some time, as it argues that competitive environments are complex and unpredictable, and therefore, organisational strategies must be reactive and flexible. As a consequence, strategies simply emerge over time, and are characterised by a process of trial and error where individuals and groups within the organisation learn more about the environment they are competing in and how best to take advantage of it.

This paper aims to explore two key questions: firstly, to examine the role that action learning could play in helping strategy makers become more reflective practitioners, and secondly, to explore the use of peer consultancy as a vehicle to enable action learning. This paper presents the findings of empirical research from an action learning project with the Chief Executive of a leading UK service provider of health and fitness. It provides a detailed examination of how a service management strategy was developed in practice and enabled by a process of iterative action, change, reflection and learning.

Chameleon effects in homework research: The homework–achievement association depends on the measures used and the level of analysis chosen

Using a data set specifically tailored to homework research, with a sample of 1275 students from 70 classes in Switzerland, the association between homework and achievement in French as a second language was tested at three levels (class level, between-student level, and within-student level). The strength and direction of the homework–achievement association depended on the homework indicator chosen and differed to some degree across analytical levels. At the class level, achievement was higher in classes set frequent homework assignments and in classes where students reported low overall levels of negative emotions when doing homework. At the between-student level, high individual homework effort and low levels of negative homework emotions predicted favorable developments in French achievement, whereas high homework time predicted lower achievement. At the intraindividual level, high homework effort, high homework time, and low levels of negative homework emotions were statistically significantly associated with positive student evaluations of the learning gains from the specific assignment.     

Shared misunderstandings? Competing and conflicting meaning structures in quality assurance

This article shows how the professional discourse on quality assurance in higher education is building on latent meaning structures that can be competing with each other and even subvert the messages on the manifest level. Taking the case of the Austrian higher education system as an example and employing a reconstructive-interpretative approach rooted in social science hermeneutics, five different meaning patterns are presented: a consumer protection pattern, an educative pattern, an entrepreneurial pattern, a managerial pattern and a quality engineering pattern. By analysing and comparing these patterns, the study argues for paying more attention to latencies and implicit meanings that might be overlooked by focusing on the manifest level of the discourse, in order to not lose track of important contradictions and sources of potential conflict.
