Comparing variation theory with Piaget’s theory of cognitive development: more similarities than differences?

ABSTRACT

Lo’s variation theory is a learning and teaching theory based on Marton’s phenomenographic approach and is one of the most important backbones of learning studies. The proponents of variation theory demarcate their approach from constructivist learning approaches, stressing constructivism as philosophical framework, but not as learning theory. At the same time, the phenomenographic approach emphasizes the importance of Piaget’s work about the cognitive development, which should be considered when talking about learning and teaching. We argue that – from a theoretical point of view – Piaget’s theory of how cognitive schemata are developed and how variation theory proposes that learning can be fostered entails many similarities which are not apparent at first glance. We demonstrate the similarities and differences using a teaching example from an English as second language classroom and show the implications for practical instructional work. Finally, we discuss concrete suggestions how variation theory could benefit even more from Piaget’s theory.     

A Longitudinal Study of Two Early Intervention Strategies: Project CARE

65 families with children at risk for cognitive difficulties were randomly assigned at the time of the child's birth to 1 of 3 groups, 2 intervention and 1 control. For the most intensive intervention group, family education was combined with a center-based educational day-care program; the less intensive intervention group received the home-based family education program only. To assess the cognitive performance of children, The Bayley Scales of Infant Development were administered at 6, 12, and 18 months; the Stanford-Binet Intelligence Test at 24, 36, and 48 months; and the McCarthy Scales of Children's Abilities at 30, 42, and 54 months. On each test after the 6-month assessment, scores of children in the educational day-care plus family support group were greater than those in the other 2 groups. No cognitive intervention effects were obtained for the family education group. Group effects were not obtained for measures of either the quality of the home environment or parent attention.     

The crisis discourse of a wicked policy problem: vocational skills training in Australia

In 2007 the Rudd Labor government in Australia introduced significant changes to education policy for the nation. The Skilling Australia’s Future (Rudd et al. Skilling Australia for the future. Election 2007 policy document, 2007) policy was meant to redress a perceived failure by the previous Howard federal Liberal-National Coalition governments to fund and manage vocational skills training adequately. The Skilling Australia’s Future policy established a number of areas for immediate action. This paper looks at one of these areas from the policy document, namely, the Rudd government’s plan for addressing skills shortages (Rudd et al. 2007, pp. 4–9) through the establishment of Trade Training Centres in schools. The policy is analysed using Critical Discourse Analysis, featuring the semiotic concept of intertextuality. Findings from the application of this method suggest that Skilling Australia’s Future (2007) belongs within a history of like-minded policy and, although a new direction is provided by the allocation of Trade Training Centres to selected high schools, the policy is not clearly separable from the market-driven discourse that has pervaded education policy since the 1990s.     

The Power of Doing: A Learning Exercise that Brings the Central Limit Theorem to Life

This article demonstrates an active learning technique for teaching the Central Limit Theorem (CLT) in an introductory undergraduate business statistics class. Groups of students carry out one of two experiments in the lab, tossing a die in sets of 5 rolls or tossing a die in sets of 10 rolls. They are asked to calculate the sample average of each experiment. An easy‐to‐use Excel template is designed to calculate the averages from the students' dice rolls. Empirical histograms are generated dynamically for both sample sizes of 5 and 10 rolls, visually demonstrating the convergence toward a bell‐shaped distribution for the sample means. Our classroom experiences with the learning approach show that most students view it as fun and valuable to their learning of the concepts underlying the CLT.     

Pacing in lane-based head-to-head competitions: A systematic review on swimming

ABSTRACT

Athletes’ energy distribution over a race (e.g. pacing behaviour) varies across different sports. Swimming is a head-to-head sport with unique characteristics, such as propulsion through water, a multitude of swimming stroke types and lane-based racing. The aim of this paper was to review the existing literature on pacing behaviour in swimming. According to PRISMA guidelines, 279 articles were extracted using the PubMed and Web of Science databases. After the exclusion process was conducted, 16 studies remained. The findings of these studies indicate that pacing behaviour is influenced by the race distance and stroke type. Pacing behaviours in swimming and time-trial sports share numerous common characteristics. This commonality can most likely be attributed to the lane-based racing set-up. The low efficiency of swimming resulting from propulsion through the water induces a rapid accumulation of blood lactate, prompting a change in swimmers’ biomechanical characteristics, with the goal of minimising changes in velocity throughout the race. Although the literature on youth swimmers is scarce, youth swimmers demonstrate more variable pacing profiles and have more difficulty in selecting the most beneficial energy distribution.     

Web 2.0 Technologies and Back Channel Communication in an Online Learning Community

Communication, collaboration and community development are processes that contribute to student satisfaction and learning in online courses. This paper describes a study that investigated how campus and distance graduate students in a library science program communicated with one another outside the official boundaries of their courses. We conducted a survey to answer two research questions: 1) What Web 2.0 technologies do students use to communicate with one another outside of the formal structure of their online courses? and 2) What do they talk about in such communication? The results showed that, while students used a variety of technologies to communicate with one another, those enrolled at a distance made greater use of technology to communicate with one another. Moreover, clear preferences emerged according to age. Younger students preferred mobile technologies while older students experimented with a wider range of web-based technologies. We interpret these results and offer recommendations for practice based on our interpretation.     

Sex Differences in Science and Technology Among 11‐year‐old Schoolchildren: II‐‐affective

Two thousand and sixty‐five 11‐year‐olds in their first term at secondary school were given a variety of attitude and achievement tests. Overall both girls and boys had positive attitudes to science but there were substantial sex differences‐‐boys were much keener than girls to learn about physical science, and girls were keener than boys to learn about nature study and human biology. Boys had much greater experience than girls of tinkering activities, but girls had more experience of biological science activities. Boys were much more likely than girls to see science as a masculine preserve. At this age attitudes to science were virtually unrelated to achievement in science‐ and technology‐related areas. One important exception to this is that girls who saw science as masculine tended to perform worse on the cognitive tests.     

Vigilance as a Response to White Complicity

Calls for vigilance have been a recurrent theme in social justice education. Scholars making this call note that vigilance involves a continuous attentiveness, that it presumes some type of criticality, and that it is transformative. In this essay Barbara Applebaum expands upon some of these attributes and calls attention to three particular features of vigilance that, while they may be alluded to in the aforementioned discussions, are rarely made explicit. These three features are critique, staying in the anxiety of critique, and vulnerability. Using the lens of Judith Butler's recent work and the discussions that her work has provoked, Applebaum examines these three features of vigilance and demonstrates how they are crucial for white people interrogating their complicity in systemic racism. Finally, she discusses how the expanded three features of vigilance can offer guidance to one of the enormously thorny questions that arises in the social justice classroom.
