The acquisition of expertise in the classroom: Are current models of education appropriate?

The study of expertise tends to focus on humans who can perform extraordinary feats. Although the way in which expertise is acquired is often characterized as similar to everyday skill acquisition, the attainment of basic numeracy skills is rarely considered in the same context as the attainment of expertise. It is clear, though, that average numeracy skills possess all the hallmarks of expert performance. In this paper I argue that the traditional classroom of Western education systems pays insufficient attention to the idea that effective numeracy skills represent a level of expertise that requires a particular form of training. Using the five principles of skill acquisition identified by Speelman and Kirsner (2005), I argue that the modern classroom is not the most appropriate environment for acquiring important cognitive skills, and that computer programs, such as games and tailored training tasks, should be considered a valuable adjunct to traditional didactic instruction

Development support of early career researchers in the Netherlands: Lessons for Australia

Australian universities are faced with the imminent retirement of a large proportion of their researchers. One way to avoid a decrement in research performance is to consider greater support for early career researchers (ECRs). To investigate how another university system that is ranked high in research performance supports its ECRs several universities in the Netherlands were visited. Seventeen senior academic staff in these universities were interviewed to examine their perceptions of the support that is provided for the development of ECRs, and the nature of the research environment in which they are employed. Interviews were recorded, transcribed, and coded using a thematic analysis procedure that was guided by the IPA framework to identify common themes amongst the views of the interviewees. Several features of the Dutch university system were identified as different to the Australian system and which the interviewees suggested were responsible for the high level research performance exhibited by their universities. These include the organization of universities by chair groups that are responsible for both research and teaching in a subject area, tenure track systems, and generous financial and material support for developmental activities. On the basis of these findings, I recommend Australian universities consider revising the support they provide to ECRs to be more aligned with what is provided in the Dutch system

Retirement Savings Investment Strategy: Member Choices and Performance

Three crucial ingredients influence how much individuals will have to fund retirement income needs: how much they contribute to savings, how long they save for, and the performance of these savings. This paper focuses on the issue of performance, and how individuals perform when they are given the choice of making their own investment strategy for their retirement savings contributions. An empirical examination using a large sample gathered from four Australian superannuation funds is utilised and finds that on average members underperform their own funds default option both in raw returns and on a risk-adjusted basis. For trustees and regulators charged with the responsibility of looking after the interests of members an important result identifies significant differences in performance based on how members are allowed to construct their investment strategy.Retirement savings, Superannuation, Asset allocation, Investment performance Acknowledgements: The authors gratefully acknowledge the support of the four funds who supported this research.

Statements about the pervasiveness of behavior require data about the pervasiveness of behavior

Despite recent close attention to issues related to the reliability of psychological research (e.g., the replication crisis), issues of the validity of this research have not been considered to the same extent. This paper highlights an issue that calls into question the validity of the common research practice of studying samples of individuals, and using sample-based statistics to infer generalizations that are applied not only to the parent population, but to individuals. The lack of ergodicity in human data means that such generalizations are not justified. This problem is illustrated with respect to two common scenarios in psychological research that raise questions for the sorts of theories that are typically proposed to explain human behavior and cognition. The paper presents a method of data analysis that requires closer attention to the range of behaviors exhibited by individuals in our research to determine the pervasiveness of effects observed in sample data. Such an approach to data analysis will produce results that are more in tune with the types of generalizations typical in reports of psychological research than mainstream analysis methods

How mean is the mean?

In this paper we voice concerns about the uncritical manner in which the mean is often used as a summary statistic in psychological research. We identify a number of implicit assumptions underlying the use of the mean and argue that the fragility of these assumptions should be more carefully considered. We examine some of the ways in which the potential violation of these assumptions can lead us into significant theoretical and methodological error. Illustrations of alternative models of research already extant within Psychology are used to explore methods of research less mean-dependent and suggest that a critical assessment of the assumptions underlying its use in research play a more explicit role in the process of study design and review

Does mathematics training lead to better logical thinking and reasoning? A cross-sectional assessment from students to professors

Mathematics is often promoted as endowing those who study it with transferable skills such as an ability to think logically and critically or to have improved investigative skills, resourcefulness and creativity in problem solving. However, there is scant evidence to back up such claims. This project tested participants with increasing levels of mathematics training on 11 well-studied rational and logical reasoning tasks aggregated from various psychological studies. These tasks, that included the Cognitive Reflection Test and the Wason Selection Task, are of particular interest as they have typically and reliably eluded participants in all studies, and results have been uncorrelated with general intelligence, education levels and other demographic information. The results in this study revealed that in general the greater the mathematics training of the participant, the more tasks were completed correctly, and that performance on some tasks was also associated with performance on others not traditionally associated. A ceiling effect also emerged. The work is deconstructed from the viewpoint of adding to the platform from which to approach the greater, and more scientifically elusive, question: are any skills associated with mathematics training innate or do they arise from skills transfer

Stability and Accuracy of Long-Term Memory for Musical Pitch

Existing research gives an inconsistent picture of the nature of the cognitive processes underlying memory for musical information. A study was conducted to investigate the stability and accuracy of long-term memory for pitch amongst individuals who have not had musical training. Excerpts from well-known pop songs were used as stimuli. Participants heard one long sequence of excerpts, each of which had been raised or lowered in pitch by one semitone, or left unaltered. After hearing each excerpt, participants were asked to detect whether it was different from the original version of the song they remembered. Participants were significantly worse at detecting whether the pitch of an excerpt had been changed when the altered excerpt was preceded by an unaltered excerpt or vice-versa, than when they heard two consecutive unaltered excerpts. This suggests that pitch memory is subject to interference from previously presented pitch information

A theory of the mind as a complex system

Five principles of skill acquisition are presented based on a review of research on human learning and expertise. Essentially these principles state that practice leads to faster and more efficient uses of knowledge. This enables faster performance and results in less demand on mental resources. In turn these outcomes enable higher level behaviours to be attempted. Ultimately skills are developed through refinement of many component processes. A theory of the mind is proposed that borrows from theories of complex adaptive systems. In this theory, the mind is conceived of as consisting of agents that compete for resources associated with processing information. The nature of this competition is similar to that observed in physical and biological systems in that agents survive or disappear depending on their usefulness. This theory is shown to be capable of explaining the five principles of skill acquisition, without these principles being explicitly built into the theory. Implications for other theories of skill acquisition are considered
