Classroom discourse analysis and educational outcomes in the era of education reform

Background In the era of education reform when new teaching approaches are being advocated, it is important to investigate how different classroom discourse patterns are related to different educational outcomes. Aim The purpose of the study was to analyse the whole classroom discourse of two teacher interns' writing classes. It was conducted against a background of education reform in which teachers were being encouraged to make major changes in their teaching approaches. We investigated what approaches were adopted and what discourse patterns were related to better educational outcomes. Sample The participants were two teacher interns and their 61 students in Hong Kong. The students (35 boys, 26 girls) were seventh graders from two classes in the same secondary school. Method An instruction unit of each teacher intern on expository writing (120 min) was video‐recorded and analysed. Discourse analysis of the whole classroom interaction was supplemented by the students' perceptions and independent observers' evaluations of the instruction. Results The results indicated that both teacher interns adopted a traditional direct instruction although student‐centred approaches were being recommended in the education reform. The effectiveness of the instruction was associated with certain features of the classroom discourse patterns. Better educational outcomes were associated positively with utterances of high cognitive demand but negatively with utterances related to discipline. Students tended to have better performances in writing when they and the independent observers perceived that the teachers used more motivating strategies. Conclusions The effectiveness of instruction is a complicated phenomenon that involves a myriad of interrelated factors. Teacher‐ or student‐centred approaches are only part of these diverse factors.     

Happy Family Kitchen: Behavioral Outcomes of a Brief Community-Based Family Intervention in Hong Kong

Positive psychology interventions commonly involve behavioral exercises to improve psychosocial well-being. Intervention effect on behavior is unclear. The Happy Family Kitchen project, one of the community-based brief intervention projects under The FAMILY: A Jockey Club Initiative for a Harmonious Society, was conducted in Hong Kong to develop and evaluate the effectiveness of a positive psychology family intervention. We have previously reported positive intervention effects on family communication, family well-being, and subjective happiness. This paper aims to explore the effectiveness of the intervention on behavioral outcomes and their associations with psychosocial well-being. A total of 23 social service units organized and conducted intervention programs for 1419 individuals from 612 families in Hong Kong. Each intervention was developed with emphasis on one of five positive psychology themes: gratitude, flow, happiness, health, and savoring. Intervention outcomes were assessed at pre-intervention, immediate post-intervention, and 6 weeks and 12 weeks post-intervention. Results showed that family communication time and frequency of meal preparation with family members increased with sustainable small effects up to 12 weeks. Theme-specific behavior change was observed in the gratitude, flow, and happiness interventions, respectively. Family communication time, frequency of eating with family members, and theme-specific behaviors, including gratitude, flow, happiness behavior, health attitude, and health behavior, were positively associated with psychosocial well-being. Qualitative data provided additional evidence of effectiveness with in-depth insights into behavior change. The positive associations between target behaviors and well-being suggest that improvements in well-being as a function of the intervention may be associated with behavior change.     

Cognitive behaviour therapy to treating bulimia nervosa: A case study

The general cognitive behaviour therapy postulates that bulimic symptoms are maintained by a characteristic set of overvalued thoughts about the personal implications of body shape and weight. Research shows that there is both a close relationship and specific interaction between thoughts and behaviours that help to maintain the overvalued thoughts. This theoretical proposition concerning the role of behaviours in the maintenance of psychological problems is commonly accepted and empirically validated. To ensure a sustainable therapeutic change in the treatment of bulimia nervosa, therapists may need to initially target these overvalued thoughts about the personal implications of body shape and weight; and then to work on the behaviours that help to maintain the bulimic symptoms. The purpose of the present paper is to discuss the conceptual and practical issues underpinning a therapeutic focus that reflects an integrated clinical approach in the treatment of bulimia nervosa. This integrated approach includes the assessment and disputation of the overvalued thoughts that are causal to bulimia nervosa, and various strategies that facilitate the change in those behaviours that help to maintain the bulimic conditions. Using a case example, this paper also discusses the cognitive behaviour conceptualization in the maintenance of bulimia nervosa.     

What do we learn from the Implicit Association Test about intergroup attitudes in Hong Kong? The case of social identification inclusiveness and need for closure

The current study tests an implication of the Associative-Propositional Evaluation model of implicit and explicit attitude measures in Hong Kong's intergroup context. We argued that the Implicit Association Test taps associative intergroup evaluations that are not necessarily consistent with the propositional implications of one's social identification inclusiveness and need for closure. In contrast, explicit intergroup attitude measures tap propositional evaluations resulting from validating the inferences drawn from pertinent propositional information in the evaluation context. Thus, explicit intergroup attitude should be consistent with the propositional implications of social identification inclusiveness and need for closure. We tested and found support for these hypotheses in a study of Hong Kong adolescents' ( N  = 65) perception of Hong Kong people and Mainland Chinese.     

Three-Mode Factor Analysis by Means of Candecomp/Parafac

A three-mode covariance matrix contains covariances of N observations (e.g., subject scores) on J variables for K different occasions or conditions. We model such an JK×JK covariance matrix as the sum of a (common) covariance matrix having Candecomp/Parafac form, and a diagonal matrix of unique variances. The Candecomp/Parafac form is a generalization of the two-mode case under the assumption of parallel factors. We estimate the unique variances by Minimum Rank Factor Analysis. The factors can be chosen oblique or orthogonal. Our approach yields a model that is easy to estimate and easy to interpret. Moreover, the unique variances, the factor covariance matrix, and the communalities are guaranteed to be proper, a percentage of explained common variance can be obtained for each variable-condition combination, and the estimated model is rotationally unique under mild conditions. We apply our model to several datasets in the literature, and demonstrate our estimation procedure in a simulation study.     

Maternal perinatal representations and their associations with mother–infant interaction and attachment: A longitudinal comparison of Portuguese and Brazilian dyads

Prior research in Western countries (mostly the US, Canada and northern Europe) indicates that mothers' representations are associated with mother–infant interaction quality and their child's attachment security later in the first year. Fewer studies, however, have evaluated whether these associations hold for mother–infant dyads in other countries, such as Brazil and Portugal. Although these countries share a similar language and culture, they differ on societal dimensions that may affect parenting attitudes and mother–infant relationships, such as economic stress, social organisation, social policy, and the availability of services for young families. In this longitudinal study, we followed two independent samples of Brazilian and Portuguese mother–infant dyads from the perinatal period to 12 months post-partum. We assessed mothers' perinatal representations using semi-structured interviews in the first 48 hours after the infant's birth, and evaluated the associations of these representations with mother interaction quality at 9 months and infant attachment at 12 months. Results were similar in each country, corroborating prior research in single Western countries: Mothers with more positive perinatal representations were more sensitive to their infants during free play at 9 months and were more likely to have infants classified as securely attached at 12 months.
