Portfolio Development in a Secondary Teaching Credential Art Programme

This paper describes portfolio development by pre-service art teachers in a secondary teaching programme at California State University, Los Angeles, USA. A portfolio reflects knowledge, skills, and beliefs about teaching in general and teaching art specifically. It displays one’s learning experiences as they are collected, organized, and refined to provide a critical framework and rich portrayal of one’s best work. The article addresses the questions of what a portfolio in art education is, what its goals are, how one creates a portfolio, how one assesses portfolios once they are developed, what the issues and challenges surrounding the use of portfolios as assessment tools are, and finally, some likely future developments of portfolio assessment in teacher education.

Confronting dictatorship,democratization, and post‐democratization – personal reflection on intellectual and social practices in the context of dictatorship,democratization and post‐democratization

Abstract

This essay tries to trace the life trajectory of an intellectual, in terms of his intellectual and social practices, who wants to live through modern Korean history via progressive activism. The trajectory can be divided into three different stages: the first comes with the military developmental dictatorship in 1961, ending in 1987. The next is during the democratic transition since the Democratic Uprising in June 1987, which put the Korean society onto the road of democratization. The last one should be the so‐called ‘post‐democratization’ period in which we now find ourselves. This is more a story than an analysis of the progressive intellectual movement in the form of the personal recollections. The story is, however, not just about an individual but it is a window giving a glimpse into the larger trajectory that many progressive intellectuals have gone through, and that directly reflects the huge changes in contemporary history of South Korea, such as the interaction between the domination and social movements.     

Comparing the standards of one metabolic equivalent of task in accurately estimating physical activity energy expenditure based on acceleration

The purpose of the study is to analyse how the standard of resting metabolic rate (RMR) affects estimation of the metabolic equivalent of task (MET) using an accelerometer. In order to investigate the effect on estimation according to intensity of activity, comparisons were conducted between the 3.5 ml O₂ · kg^?1 · min^?1 and individually measured resting VO₂ as the standard of 1 MET. MET was estimated by linear regression equations that were derived through five-fold cross-validation using 2 types of MET values and accelerations; the accuracy of estimation was analysed through cross-validation, Bland and Altman plot, and one-way ANOVA test. There were no significant differences in the RMS error after cross-validation. However, the individual RMR-based estimations had as many as 0.5 METs of mean difference in modified Bland and Altman plots than RMR of 3.5 ml O₂ · kg^?1 · min^?1. Finally, the results of an ANOVA test indicated that the individual RMR-based estimations had less significant differences between the reference and estimated values at each intensity of activity. In conclusion, the RMR standard is a factor that affects accurate estimation of METs by acceleration; therefore, RMR requires individual specification when it is used for estimation of METs using an accelerometer.     

Do Search Algorithms Endanger Democracy? An Experimental Investigation of Algorithm Effects on Political Polarization

ABSTRACT

This study examines algorithm effects on user opinion, utilizing a real-world recommender algorithm of a highly popular video-sharing platform, YouTube. We experimentally manipulate user search/watch history by our custom programming. A controlled laboratory experiment is then conducted to examine whether exposure to algorithmically recommended content reinforces and polarizes political opinions. Results suggest that political self-reinforcement, as indicated by the political emotion-ideology alignment, and affective polarization are heightened by political videos – selected by the YouTube recommender algorithm – based on participants’ own search preferences. Suggestions for how to reduce algorithm-induced political polarization and implications of algorithmic personalization for democracy are discussed.     

The national crisis and de/reconstructing nationalism in South Korea during the IMF intervention

Abstract

This paper explores the process by which Korean nationalism was challenged and transformed through utilizing sports celebrities as iconic figures during the International Monetary Fund (IMF) intervention in South Korea. The influences of the IMF intervention were not limited to economic and political fields; rather, Korean nationalism had undergone substantial changes through the national crisis. At that time, two Korean athletes who were hugely successful in the US became national celebrities, or even national heroes in South Korea, a baseball player, Chan‐ho Park and a goler Se‐ri Pak. The media representation of these two Korean athletes is useful for the understanding of altered nationalism during the IMF intervention. The analysis of media coverage of these two athletes can be summarized in three ways: first, the coverage is focused on a self‐governing individual; second, that individual is invested with the image of economic success in global competition; and third, that individual is invested with the image of responsibility for both family and nation‐state. Conclusively, the two celebrities were presented as models for a new kind of citizenship, i.e. a national individual. Finally, this paper suggests that Korean nationalism has been altered through the IMF intervention, but remains a hegemonic ideology albeit combined with neoliberalism.

A Mixture Group Bifactor Model for Binary Responses

The presence of nuisance dimensionality is a potential threat to the accuracy of results for tests calibrated using a measurement model such as a factor analytic model or an item response theory model. This article describes a mixture group bifactor model to account for the nuisance dimensionality due to a testlet structure as well as the dimensionality due to differences in patterns of responses. The model can be used for testing whether or not an item functions differently across latent groups in addition to investigating the differential effect of local dependency among items within a testlet. An example is presented comparing test speededness results from a conventional factor mixture model, which ignores the testlet structure, with results from the mixture group bifactor model. Results suggested the 2 models treated the data somewhat differently. Analysis of the item response patterns indicated that the 2-class mixture bifactor model tended to categorize omissions as indicating speededness. With the mixture group bifactor model, more local dependency was present in the speeded than in the nonspeeded class. Evidence from a simulation study indicated the Bayesian estimation method used in this study for the mixture group bifactor model can successfully recover generated model parameters for 1- to 3-group models for tests containing testlets.
