Effect on development of proportional reasoning skill of physical experience and cognitive abilities associated with prefrontal lobe activity

The present study tested the hypothesis that maturing prefrontal lobes play a role in the development of proportional reasoning skill because the prefrontal lobes are involved in the inhibition of task‐irrelevant information and the representation of task‐relevant information. The hypothesis that reasoning development is in part dependent upon physical experience was also tested. Students (all males) who failed to solve a diagnostic proportions task were administered several tests of prefrontal lobe functions. The students were then randomly assigned to manipulative or verbal tutoring groups. Both groups received a series of individual testing, tutoring and testing sessions on proportional reasoning. As predicted, performance on the prefrontal lobe tasks (measures of inhibiting ability, planning ability, dissembedding ability, and working memory capacity) significantly predicted performance on proportional reasoning tasks following tutoring. Students' computational skills were not a significant predictor. Also, the manipulative group's proportional reasoning performance was significantly higher than that of the verbal tutoring group. Therefore, the present results provide support for the hypothesis that maturing prefrontal lobes and physical experience play roles in the development of proportional reasoning skill. © 2000 John Wiley & Sons, Inc.

Development of Scientific Reasoning in College Biology: Do Two Levels of General Hypothesis‐Testing Skills Exist?

The primary purpose of the present study was to test the hypothesis that two general developmentally based levels of hypothesis‐testing skills exist. The first hypothesized level presumably involves skills associated with testing hypotheses about observable causal agents; the second presumably involves skills associated with testing hypotheses involving unobservable entities. To test this hypothesis, a hypothesis‐testing skills test was developed and administered to a large sample of college students both at the start and at the end of a biology course in which several hypotheses at each level were generated and tested. The predicted positive relationship between level of hypothesis‐testing skill and performance on a transfer problem involving the test of a hypothesis involving unobservable entities was found. The predicted positive relationship between level of hypothesis‐testing skill and course performance was also found. Both theoretical and practical implications of the findings are discussed. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 81–101, 2000     

Influence of a Reflective Explicit Activity‐Based Approach on Elementary Teachers' Conceptions of Nature of Science

This study assessed the influence of a reflective, explicit, activity‐based approach to nature of science (NOS) instruction undertaken in the context of an elementary science methods course on preservice teachers' views of some aspects of NOS. These aspects included the empirical, tentative, subjective (theory‐laden), imaginative and creative, and social and cultural NOS. Two additional aspects were the distinction between observation and inference, and the functions of and relationship between scientific theories and laws. Participants were 25 undergraduate and 25 graduate preservice elementary teachers enrolled in two sections of the investigated course. An open‐ended NOS questionnaire coupled with individual interviews was used to assess participants' NOS views before and at the conclusion of the course. The majority of participants held naive views of the target NOS aspects at the beginning of the study. During the first week of class, participants were engaged in specially designed activities that were coupled with explicit NOS instruction. Throughout the remainder of the course, participants were provided with structured opportunities to reflect on their views of the target NOS aspects. Postinstruction assessments indicated that participants made substantial gains in their views of some of the target NOS aspects. Less substantial gains were evident in the case of the subjective, and social and cultural NOS. The results of the present study support the effectiveness of explicit, reflective NOS instruction. Such instruction, nonetheless, might be rendered more effective when integrated within a conceptual change approach. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 295–317, 2000.     

My Wild Lily: a self‐criticism from a participant in the March 1990 student movement 1

Abstract

The ‘Wild Lily’ student sit‐in in March 1990 was often praised in the later political transformation process as a crucial moment when the ‘pure and innocent’ students facilitated democratization in Taiwan. From the perspective of a participant in the protest, the author argues that the sit‐in was actually a failure of the ‘popular democratic’ wing of Taiwan's student movement in the 1980s, which championed a more radical vision of democracy. The idea of ‘popular democracy’ was an anti‐elitist ideology arising from critiques on the elite‐led political reform movement. However, due to its historical constraint, practices along this line were unable to alter the bourgeois democratic character of 1980s' democratization process in Taiwan.     

Capitalizing the big man: Yao Ming,Asian America,and the China Global1

In summer 2002, Yao Ming, the Chinese basketball player from Shanghai, was drafted by the Houston Rockets as the overall first‐pick. His advent to the NBA quickly brought about a phenomenal impact, both economically and culturally. He was not only voted by the fans to the All‐Star game and replaced Shaquille O'Neal as one of the starting five in the Western Conference team, but also boosted the ticket sales of the Rockets' game to an increasing Asian American spectatorship. Instantly, he is more than the ‘little giant’ from China, but the great ‘yellow hope’ for Asian Pacific Americans — representing the ‘Chinese’ and the Chinese market in the age of globalization. Considering entertainment sports as a distinct place for transnational labour and commodity transactions, this paper takes Yao and his proliferating cultural economic impact as an occasion to analyse and critique the China Global as a national‐capitalist fantasy that is materialized at the expense of ‘stylized’ bodies. Acknowledging, although not endorsing, Julianne Malveaux's crude metaphor of basketball plantation, this paper suggests that Yao articulates a different mode of global capitalism than that represented by Michael Jordan in the 1990s. This mode of global capitalism is not so much about the labour of conquest as epitomized by black athletes, but about the attraction of the market and the availability of labour supply as inscribed in the history of Chinese immigration. The American dream of Yao, ultimately, is the capitalist and nationalist desire for ‘bigness’.     

Asianism in Korea’s politics of identity

Abstract

This article examines Korea’s politics of identity in the form of Asianism in the modern period, especially since Korea’s incorporation into the modern world system in the late nineteenth century. Asianism, and regionalism generally, has become a salient policy strategy for the current South Korean government. However, Asianism has been a primary ideological current in modern Korea whose most recent incarnation should be understood in the larger historical context. This study traces the development of Asianism in four different periods: precolonial, colonial, Cold War, and post‐Cold War. Initially emerging as a bulwark against Western encroachment, the Asianism narrative became irrelevant upon Japanese annexation of Korea in 1910 and only survived as a discourse about a glorified cultural past during colonial rule. Upon liberation, Asianism rescinded as the Japan‐centered regional order was replaced by a new Cold War alignment, capitalist (Japan, South Korea, and Taiwan) versus communist (China and North Korea). Although discussion about Asianism and a new East Asian regional order have recently resurfaced, the historical legacy of colonialism, war, and national division has added much complexity to the debate. Explicating how the Asianism narrative emerged and evolved through these various historical contexts sheds light on the complexities and difficulties inherent in the current attempt to forge an Asian regional order. By looking at Asianism from a historical perspective, we can also better appreciate the continuity and discontinuity in Korea’s politics of identity. While it is still uncertain what the foundation of a new Asianism will be, it is equally obvious that regional interactions will continue to be an important part of the global world order. This study concludes with policy implications of how a historically sensitive understanding of the development of an Asian regional identity can further interaction and integration of East Asian nations.
