Teachers’ perceptions of student evaluations of teaching

Evaluation of teaching in higher education has drawn much attention due to the need for greater accountability and improvement in student learning. Our review of literature on Student Evaluation of Teaching (SET) surveys suggests that considerable controversy and criticism have surrounded its use, fairness, and validity. Yet, many universities in Hong Kong are depending primarily on student feedback in SET surveys to provide evidence for their improvement of teaching and learning, and for their decisions made on teachers' pay-rise and tenure. If universities are to continue to use SET surveys as the main source of mechanism for measuring teaching effectiveness, teachers will have to understand and be aware of its purposes. But how much do we know about teachers' perceptions of teaching and learning and, consequently, their opinions of using SET surveys as the primary standardized evaluation mechanism of teaching for promotion and tenure and for teaching effectiveness?     

Measurement of active drag during crawl arm stroke swimming

In order to measure active drag during front crawl swimming a system has been designed, built and tested. A tube (23 m long) with grips is fixed under the water surface and the swimmer crawls on this. At one end of the tube, a force transducer is attached to the wall of the swimming pool. It measures the momentary effective propulsive forces of the hands. During the measurements the subjects’ legs are fixed together and supported by a buoy. After filtering and digitizing the electrical force signal, the mean propulsive force over one lane at constant speeds (ranging from about 1 to 2 m s^‐1) was calculated. The regression equation of the force on the speed turned out to be almost quadratic. At a mean speed of 1.55 m s^‐1 the mean force was 66.3 N. The accuracy of this force measured on one subject at different days was 4.1 N. The observed force, which is equal to the mean drag force, fits remarkably well with passive drag force values as well as with values calculated for propulsive forces during actual swimming reported in the literature. The use of the system does not interfere to any large extent with normal front crawl swimming; this conclusion is based on results of observations of film by skilled swim coaches. It was concluded that the system provides a good method of studying active drag and its relation to anthropometric variables and swimming technique.     

Inquiry-based science education: scaffolding pupils’ self-directed learning in open inquiry

ABSTRACT

This paper describes a multiple case study on open inquiry-based learning in primary schools. During open inquiry, teachers often experience difficulties in balancing support and transferring responsibility to pupils’ own learning. To facilitate teachers in guiding open inquiry, we developed hard and soft scaffolds. The hard scaffolds consisted of documents with explanations and/or exercises regarding difficult parts of the inquiry process. The soft scaffolds included explicit references to and additional explanations of the hard scaffolds. We investigated how teacher implementation of these scaffolds contributed to pupils’ self-directed learning during open inquiry. Four classes of pupils, aged 10–11, were observed while they conducted an inquiry lesson module of about 10 lessons in their classrooms. Data were acquired via classroom observations, audio recordings, and interviews with teachers and pupils. The results show that after the introduction of the hard scaffolds by the teacher, pupils were able and willing to apply them to their investigations. Combining hard scaffolds with additional soft scaffolding promoted pupils’ scientific understanding and contributed to a shared guidance of the inquiry process by the teacher and her pupils. Our results imply that the effective use of scaffolds is an important element to be included in teacher professionalisation.     

Initial development of a model of care and support for primary school children in changing familial situations: a Hong Kong hybrid case

This paper proposes an initial model for the care and support of primary school children coping with family situations and family changes. The model is built on existing counselling literature, incorporating the perceptions of teachers, children and parents on their needs for support and a small empirical study by the author on teachers' perceptions of the roles and functions of the personnel involved in supporting children in changing familial situations. In proposing the model for schools the author argues for the need for a multi‐systemic approach which emphasises involving home–school cooperation and acknowledging the unique ‘East meets West’ hybrid context in Hong Kong. The use of the model in relation to teacher education, counselling practice and research is discussed. Implications of this model for other locales having similar hybrid contexts, particularly a mix with a Chinese cultural heritage, are also discussed.     

Re-examining the effects of adding relevance information in a relevance feedback environment

This paper presents an investigation about how to automatically formulate effective queries using full or partial relevance information (i.e., the terms that are in relevant documents) in the context of relevance feedback (RF). The effects of adding relevance information in the RF environment are studied via controlled experiments. The conditions of these controlled experiments are formalized into a set of assumptions that form the framework of our study. This framework is called idealized relevance feedback (IRF) framework. In our IRF settings, we confirm the previous findings of relevance feedback studies. In addition, our experiments show that better retrieval effectiveness can be obtained when (i) we normalize the term weights by their ranks, (ii) we select weighted terms in the top K retrieved documents, (iii) we include terms in the initial title queries, and (iv) we use the best query sizes for each topic instead of the average best query size where they produce at most five percentage points improvement in the mean average precision (MAP) value. We have also achieved a new level of retrieval effectiveness which is about 55–60% MAP instead of 40+% in the previous findings. This new level of retrieval effectiveness was found to be similar to a level using a TREC ad hoc test collection that is about double the number of documents in the TREC-3 test collection used in previous works.     

Temporal networks in collaborative learning: A case study

Social Network Analysis (SNA) has enabled researchers to understand and optimize the key dimensions of collaborative learning. A majority of SNA research has so far used static networks, ie, aggregated networks that compile interactions without considering when certain activities or relationships occurred. Compressing a temporal process by discarding time, however, may result in reductionist oversimplifications. In this study, we demonstrate the potentials of temporal networks in the analysis of online peer collaboration. In particular, we study: (1) social interactions by analysing learners' collaborative behaviour, part of a case study in which they worked on academic writing tasks, and (2) cognitive interactions through the analysis of students' self-regulated learning tactics. The study included 123 students and 2550 interactions. By using temporal networks, we show how to analyse the longitudinal evolution of a collaborative network visually and quantitatively. Correlation coefficients with grades, when calculated with time-respecting temporal measures of centrality, were more correlated with learning outcomes than traditional centrality measures. Using temporal networks to analyse the co-temporal and longitudinal development, reach, and diffusion patterns of students' learning tactics has provided novel insights into the complex dynamics of learning, not commonly offered through static networks.     

Child and home predictors of early numeracy skills in kindergarten

The present study investigated the influence of home numeracy experiences on early numeracy skills in kindergarten after controlling for cognitive and linguistic precursors. Eighty-nine children (mean age = 6.1 years) were tested on cognitive, linguistic, and early numeracy skills, and their parents completed a questionnaire on home numeracy practices and expectations. The results showed a unique contribution of parent–child numeracy activities and parents’ numeracy expectations on early numeracy outcomes next to individual child factors (i.e., early literacy skills and grammatical ability), stressing the importance of home numeracy experiences on early numeracy skills.     

Can research realise a bit of utopia? The impact of action research on the policy of childcare in Flanders

For the past 10 years, there has been ongoing research at the University of Ghent on professionalism in childcare (the 0–3 age group) in the Flemish Community of Belgium. This research has been inspired by the ‘Contesting Early Childhood’ movement, which is based on the premise that pedagogic research can lead to social change. The first studies dealt with the relationship between gender and professionalism (2002–2010). These ‘Men in Childcare’ studies were embedded in a campaign to increase the number of male workers. Between 2005 and 2008 a PhD study focused on the de-professionalisation that has taken place within the Flemish childcare sector. This study, ‘The construction of a new profession’, was part of a large European Social Fund project involving many partners across Europe. This article aims not only to shed light on the results of these studies, but also to delve into the influences that these projects and studies have had on political decision-making through their embedding in large ‘communicative spaces’.     

Laughter,smiles and grins: The role of humor in learning and facilitating

Abstract

This article inquires into the role of humor in the relational learning process that takes place in adventure education programs. It presents program episodes, which the authors experienced in their practice as facilitator, staff trainer and researcher, and explores the related literature. Four aspects appear to affect whether humor either facilitates or interferes with participants' learning in development programs. First, humor plays a role in developing relationships among participants and between participants and facilitators, and hence in the relational safety that characterizes an environment conducive to learning. Second, it may play a role in creating a workable distance to sensitive learning issues. Third, humor may offer new and unexpected perspectives, which contribute to revising familiar but restrictive reference frames. Finally, humor seems to fulfill these functions to the extent that it is not planned to do so, and as such may exemplify the ‘paradox of functionality’ in relational processes.     

Towards a hybrid conceptualisation of Chinese women primary school teachers' changing femininities – a case study of Hong Kong

In this paper, I posit a hybrid conceptualisation of women teachers' identities in the globalising and localising negotiation of gender. Drawing on Homi Bhabha's theory of hybridities, this paper argues for a fluid, hybrid and multifaceted reality of women teachers' lives in the areas of family, the husband and wife relationship, and the place of the child in the family as they engage in workplaces. The analysis draws on in‐depth interviews with 20 Chinese women primary school teachers first individually and then in groups of four or five in Hong Kong where globalisation meets with the indigenous Chinese culture. Implications for teacher education are discussed.
