Motivation and engagement in the ‘Asian Century’: a comparison of Chinese students in Australia,Hong Kong,and Mainland China

The present study investigated multidimensional motivation and engagement among Chinese middle school students in Australia (N?=?273), Hong Kong (N?=?528), and Mainland China (N?=?2106; randomly selected N?=?528). Findings showed that a multidimensional model of motivation and engagement fit very well for all three groups. Multi-group invariance tests showed that the number of factors, factor loadings, factor correlations and item uniquenesses were invariant across the three groups – as were inter-correlations with a set of cognate correlates (class participation, school enjoyment, positive intentions, academic buoyancy) – hence no differences of ‘kind’. However, differences of ‘degree’ were indicated through significant mean-level effects between groups, with self-reports favouring Australian Chinese students over Hong Kong and (to a lesser extent) Mainland Chinese students. We propose these findings shed important light on Chinese students’ academic motivation and engagement and also on socio-cultural perspectives on motivation and engagement because they assist understanding about effects attributable to context and effects attributable to ethnicity. Given this, the study is a timely contribution to current understanding of the Chinese learner in this, the ‘Asian Century’.     

Pedophilic sexual interests and psychopathy in child sexual abusers working with children

Research has identified stable and dynamic characteristics in child sexual abusers working with children (CSA-W) that may distinguish them from other child sexual abusers (CSA). However, in previous research CSA-W have usually been included in the group of extra-familial CSA (CSA-E). Two hundred and forty-eight forensic-sexological reports about CSA conducted by the Federal Evaluation Centre for Violent and Sexual Offenders in the Austrian Prison System were evaluated retrospectively. One hundred and nineteen intra-familial CSA (CSA-I), 66 CSA-E, and 38 CSA-W were compared with regard to static risk factors, indicators of psychopathy, and pedophilic sexual interests. CSA-E had the highest risk of recidivism as measured by the Static-99 total score, followed by CSA-W. Furthermore, CSA-E had more previous convictions than CSA-W. Both CSA-E and CSA-I had higher total scores on the Psychopathy Checklist-Revised than CSA-W. CSA-W had the highest prevalence of pedophilia diagnoses according to DSM-IV-TR criteria, as well as the highest rate of pedophilia with an orientation toward male children, and the highest frequency of male victims. CSA-W also had the highest total scores in the Screening Scale for Pedophilic Interests. CSA-W seem to constitute a group with particular risk factors and criminogenic needs, that is, they show more indicators of pedophilic sexual interests but less general antisociality and psychopathy, and would thus seem to be distinguishable from other CSA. Future research should focus in particular on evaluating differences in the grooming strategies used by CSA-W to commit and disclose child sexual abuse, as well as on the resources of this particular offender group.     

School decentralization as a process of differentiation,hierarchization and selection

The Austrian ‘school autonomy policy’, which allowed schools to develop specific ‘curricular profiles’, is taken as an example for discussing processes and effects of school decentralization policies. Data from school case studies (based on qualitative interviews and document analysis) are used to analyse and interpret the processes by which schools and teachers take up policy innovations and translate it into action and structures on school and classroom level. These policy changes and the resulting governance regimes are examined from a perspective on changing modes of ‘action coordination’ between actors on different levels of a school system and from an attention to processes of ‘re-contextualization’ in multi-level governance systems. The main result is that the Austrian decentralization policy – although not explicitly based on a market approach – boosted principles of competitive coordination between schools. In consequence, it resulted in processes of differentiation and hierarchization of schools and classes and offered new legitimatory and practical opportunities for student selection.     

Translating words into equations: a cognitive load theory approach

The conditions under which explicit instruction in checking, combined with worked examples, may be beneficial in learning how to translate sentences into algebraic equations was examined from the perspective of cognitive load theory. In two experiments it was shown that Grade 8 and 9 students were initially disadvantaged by the inclusion of a checking method. However, after a more substantial period of acquisition, students with a low level of mathematical knowledge performed significantly better after receiving checking instructions than those who did not receive checking instructions. In contrast, higher knowledge students were continually disadvantaged by the inclusion of a checking method. The positive effect of checking for lower knowledge students and the negative effect for higher knowledge students in this domain is a further example of the expertise reversal effect.     

Fifth graders' science inquiry abilities: A comparative study of students in hands‐on and textbook curricula

A large number of American elementary school students are now studying science using the hands‐on inquiry curricula developed in the 1990s: Insights; Full Option Science System (FOSS); and Science and Technology for Children (STC). A goal of these programs, echoed in the National Science Education Standards, is that children should gain “abilities to do scientific inquiry” and “understanding about scientific inquiry.” We have studied the degree to which students can do inquiries by using four hands‐on performance assessments, which required one or three class periods. To be fair, the assessments avoided content that is studied in depth in the hands‐on programs. For a sample of about 1000 fifth grade students, we compared the performance of students in hands‐on curricula with an equal number of students with textbook curricula. The students were from 41 classrooms in nine school districts. The results show little or no curricular effect. There was a strong dependence on students' cognitive ability, as measured with a standard multiple‐choice instrument. There was no significant difference between boys and girls. Also, there was no difference on a multiple‐choice test, which used items released from the Trends in International Mathematics and Science Study (TIMSS). It is not completely clear whether the lack of difference on the performance assessments was a consequence of the assessments, the curricula, and/or the teaching. © 2006 Wiley Periodicals, Inc.

The Interplay of Teacher and Student Actions in the Teaching and Learning of Geometric Proof

Proof and reasoning are fundamental aspects of mathematics. Yet, how to help students develop the skills they need to engage in this type of higher-order thinking remains elusive. In order to contribute to the dialogue on this subject, we share results from a classroom-based interpretive study of teaching and learning proof in geometry. The goal of this research was to identify factors that may be related to the development of proof understanding. In this paper, we identify and interpret students' actions, teacher's actions, and social aspects that are evident in a classroom in which students discuss mathematical conjectures, justification processes and student-generated proofs. We conclude that pedagogical choices made by the teacher, as manifested in the teacher's actions, are key to the type of classroom environment that is established and, hence, to students' opportunities to hone their proof and reasoning skills. More specifically, the teacher's choice to pose open-ended tasks (tasks which are not limited to one specific solution or solution strategy), engage in dialogue that places responsibility for reasoning on the students, analyze student arguments, and coach students as they reason, creates an environment in which participating students make conjectures, provide justifications, and build chains of reasoning. In this environment, students who actively participate in the classroom discourse are supported as they engage in proof development activities. By examining connections between teacher and student actions within a social context, we offer a first step in linking teachers' practice to students' understanding of proof.     

The cognitive habitus: its place in a realist account of inequality/difference

The existence of social differences in educational achievement as a social fact presents the sociology of education with a challenge to which it has responded with indifferent success. It is argued that contemporary explanations that dismiss the existence and relevance of differences in cognitive performance arising as a consequence of class variation in socialisation are likely to misrepresent the real causes of inequality/difference. The substantive discussion, organised around six questions dealing with the explanatory capacity of this concept, suggests that a satisfactory theory of inequality of educational opportunity will need to concern itself with the effects of socialisation on cognition. Some implications for educational practice and policy‐making are briefly noted in conclusion.
