Talk the talk: Learner-generated podcasts as catalysts for knowledge creation

Podcasting allows audio content from one or more user-selected feeds or channels to be automatically downloaded to one's computer as it becomes available, then later transferred to a portable player for consumption at a convenient time and place. It is enjoying phenomenal growth in mainstream society, alongside other Web 2.0 technologies that enable Internet users to author and distribute rich media content quickly and easily. Instead of using the technology for the mere recording and dissemination of lectures and other instructor-centred information, the project reported on in this article focused on enabling students to create their own podcasts for distribution to their peers. The article describes how engaging in the podcasting exercise promoted collaborative knowledge building among the student-producers, as evidenced through focus-group interviewing and an analysis of the products of their shared dialogue and reflection. The findings suggest that the collaborative development of audio learning objects enabling student conceptualisations of disciplinary content to be shared with peers is a powerful way of stimulating both individual and collective learning, as well as supporting social processes of perspective-taking and negotiation of meaning that underpin knowledge creation.     

Spirit of the game: Empowering students as designers in schools?

The aim of this paper and the one which follows is to explore how the potential of computer games may be taken up in schools to support learning engagement among students. It is not the intention of the papers to dismiss existing classroom practices or overlook accounts of innovative practices in schools; the papers' aim is to provide educators who are interested in exploring the use of computer games in schools with information and ideas about how these games may be effectively used to engage students in their learning. This paper questions whether the empowerment of students to create games for one another based on the school curriculum may address the insignificance of computer games in the sociocultural setting of the school. Both papers have been commissioned by Microsoft (Asia‐Pacific) under the Partners‐In‐Learning Initiative. Under this initiative, Microsoft establishes partnerships with ministries of education, national and local government bodies, and other stakeholders to empower students and teachers to realize their full potential, mediated by information and communication technologies.     

Arguing to learn and learning to argue: Case studies of how students' argumentation relates to their scientific knowledge

In this study we investigated junior high school students' processes of argumentation and cognitive development in science and socioscientific lessons. Detailed studies of the relationship between argumentation and the development of scientific knowledge are rare. Using video and audio documents of small group and classroom discussions, the quality and frequency of students' argumentation was analyzed using a schema based on the work of Toulmin ( 1958 ). In parallel, students' development and use of scientific knowledge was also investigated, drawing on a schema for determining the content and level of abstraction of students' meaning‐making. These two complementary analyses enabled an exploration of their impact on each other. The microanalysis of student discourse showed that: (a) when engaging in argumentation students draw on their prior experiences and knowledge; (b) such activity enables students to consolidate their existing knowledge and elaborate their science understanding at relatively high levels of abstraction. The results also suggest that students can acquire a higher quality of argumentation that consists of well‐grounded knowledge with a relatively low level of abstraction. The findings further suggest that the main indicator of whether or not a high quality of argument is likely to be attained is students' familiarity and understanding of the content of the task. The major implication of this work for developing argumentation in the classroom is the need to consider the nature and extent of students' content‐specific experiences and knowledge prior to asking them to engage in argumentation. © 2007 Wiley Periodicals, Inc.

Examining Hong Kong students’ achievement goals and their relations with students’ perceived classroom environment and strategy use

This study examined Hong Kong students’ achievement goals and their relations with students’ perceived classroom environment and strategy use based on the multiple goal perspective of goal orientation theory. A total of 925 Grade 8 students from six secondary schools in Hong Kong voluntarily responded to a questionnaire that measured these three sets of variables. Consistent with previous studies using goal orientation theory, the findings of this study indicated that students’ perceived classroom environment was significantly related to their personal achievement goals and strategy use. While mastery goals were found to be the strongest predictor of strategy use, performance‐approach goals and perceived instrumentality also had positive relations with mastery goals and strategy use. Our findings suggest that mastery goals and performance goals were not contrasting goals as conceptualised in normative goal orientation theory. Students with high motivation for both types of goal were more adaptive in learning than were students who pursued a single type of goal. Moreover, the value of adding perceived instrumentality when studying students’ motivation should be emphasised. The implications of these findings for understanding Hong Kong students’ motivation, and for planning effective teaching instruction to enhance their motivation, are discussed.     

Supervisors’ experiences in supervising higher education students from culturally and linguistically diverse backgrounds during work-integrated learning of health and non-health courses

The growing number of students who are culturally and linguistically diverse (CALD) relative to the host university undertaking fieldwork placements raises questions about how to best support their needs and the needs of their fieldwork supervisors so as to maximize the experience for both parties. This research aims to quantify and compare fieldwork supervisors’ perceptions of CALD versus non-CALD students’ performance during placements, the areas and levels of concern they experience in providing this supervision. Placement supervisors from health and non-health courses affiliated with an Australian University were randomly assigned to a survey containing question sets relating to their experiences in supervising CALD (n = 153) or non-CALD students (n = 168). The survey comprised Likert scale questions assessing “pressure points” to supervision and open-ended questions including strategies fieldwork supervisors typically used to assist students. Using univariate ordinal logistic regression analyses, “speaking” (coefficient, 95% CI 2.1 (1.56, 2.65)), “writing” in English (1.69 (1.17, 2.20)), and “adapting to culture of workplaces” (1.20 (0.71, 1.69)) were perceived by placement supervisors as the top “pressure points” in supervising CALD students. Interaction effects demonstrated that “difficulties in assessing CALD students’ competency” (coefficient, 95% CI?1.14 (?2.27, ?0.01), “feeling competent in supervising students for placements” (1.35 (0.26, 2.45)), and the “perception of lack of support” from either the university or employing organization (?1.70 (?2.83, ? 0.56)) were evident within fieldwork placement of health courses only. These results can assist universities and placement organizations to prioritize resources to address the key areas affecting CALD students’ performance on placements, and to improve supervisors’ experience in supervising CALD students on placements in health courses.

     

Studying Score Stability with a Harmonic Regression Family: A Comparison of Three Approaches to Adjustment of Examinee‐Specific Demographic Data

For assessments that use different forms in different administrations, equating methods are applied to ensure comparability of scores over time. Ideally, a score scale is well maintained throughout the life of a testing program. In reality, instability of a score scale can result from a variety of causes, some are expected while others may be unforeseen. The situation is more challenging for assessments that assemble many different forms and deliver frequent administrations per year. Harmonic regression, a seasonal‐adjustment method, has been found useful in achieving the goal of differentiating between possible known sources of variability and unknown sources so as to study score stability for such assessments. As an extension, this paper presents a family of three approaches that incorporate examinees' demographic data into harmonic regression in different ways. A generic evaluation method based on jackknifing is developed to compare the approaches within the family. The three approaches are compared using real data from an international language assessment. Results suggest that all approaches perform similarly and are effective in meeting the goal. The paper also discusses the properties and limitations of the three approaches, along with inferences about score (in)stability based on the harmonic regression results.     

The origin of centrality deficit in text memory and comprehension by poor comprehenders: a think-aloud study

The present study employed a think-aloud method to explore the origin of a centrality deficit (i.e., poor recall of central ideas) found in poor comprehenders (PC). Moreover, utilizing the diverse think-aloud responses, we examined the overall quality of text processing employed by PC during reading, in order to shed more light on the cognitive underpinnings underlying their poor comprehension and memory after reading. To address these goals, adolescents with good and poor comprehension, matched on reading (decoding) skills, were asked to state aloud whatever comes to their mind during the reading of two expository texts. After reading, the participants freely recalled text ideas and answered multiple-choice questions on the texts. Results indicated that PC exhibited lower performance than good comprehenders (GC) on the recall and comprehension tasks. The think-aloud protocols indicated that PC generated fewer responses than GC that reflect high-level, deep text processing, and more responses that reflect low-level, surface text processing. Furthermore, compared to GC, PC reinstated fewer prior text ideas, with this reduction being significantly greater for central than for peripheral ideas. Finally, the proportions of deep processing responses in general were positively associated with participants’ performance on recall and comprehension tasks. These findings suggest that PC exhibit poor text comprehension and memory, particularly of central ideas, because they construct a low-quality, poorly-connected text representation during reading, and produce fewer, less-elaborated retrieval cues for subsequent text comprehension and memory. This explanation is further illuminated in the context of previous findings and theoretical accounts.

     

Computational Thinking from a Disciplinary Perspective: Integrating Computational Thinking in K-12 Science,Technology, Engineering,and Mathematics Education

This article provides an introduction for the special issue of the Journal of Science Education and Technology focused on computational thinking (CT) from a disciplinary perspective. The special issue connects earlier research on what K-12 students can learn and be able to do using CT with the CT skills and habits of mind needed to productively participate in professional CT-integrated STEM fields. In this context, the phrase “disciplinary perspective” simultaneously holds two meanings: it refers to and aims to make connections between established K-12 STEM subject areas (science, technology, engineering, and mathematics) and newer CT-integrated disciplines such as computational sciences. The special issue presents a framework for CT integration and includes articles that illuminate what CT looks like from a disciplinary perspective, the challenges inherent in integrating CT into K-12 STEM education, and new ways of measuring CT aligned more closely with disciplinary practices. The aim of this special issue is to offer research-based and practitioner-grounded insights into recent work in CT integration and provoke new ways of thinking about CT integration from researchers, practitioners, and research-practitioner partnerships.

     

Australian academics and transnational teaching: an exploratory study of their preparedness and experiences

Australia is now the third largest provider of education to overseas students. Between 1994 and 2000 the number of overseas students taught by Australian universities increased by 150% to 107,622. It is estimated that 41% of the recent growth in international education has been in offshore enrolments, with each of Australia’s 38 universities now providing offshore education. This paper reviews recent Australian literature on transnational teaching and presents an overview of a study with academics who teach transnationally and who are drawn from nine Australian universities. The study covers the professional development and teaching experiences of these academics and their perceptions of the induction/orientation and ongoing professional development needed to support the delivery of quality trans‐cultural education offshore.     

Changing Ideopolitical Emphases in Moral Education in China: An Analysis of the CCP Central Committee Documents

With the understanding that moral education is interpreted as both ideological and political education in China, this paper attempts to look at the ideopolitical emphases in government moral education documents since the adoption of the open policy in 1978. The analysis will be focused on three particular aspects, namely (1) the changing perception of the role of moral education, (2) the changing emphasis on what moral education should achieve, and (3) how such change of emphases would reflect the changing social and political circumstances in China. In sum, this paper argues that government documents on moral education can be a significant indicator for tracking social transition in China.
