Building preschool teachers’ capacity for teaching Chinese to ethnic minority children in Hong Kong: A qualitative study

ABSTRACT

Teaching Chinese to second language learners is a challenge for preschool teachers in Hong Kong so effective teacher professional development programmes are urgently needed to enhance their knowledge and skills. An Integrative Model Teacher Professional Development Programme which incorporates three theoretical underpinnings (i.e., culturally responsive teaching, meaningful and pleasurable learning, and effective teaching of Chinese as a second language) is designed to equip preschool teachers with knowledge, skills, and awareness in teaching Chinese to ethnic minority students. Through qualitative interviews with 15 in-service preschool teachers who joined the Programme, teachers’ perceptions and changes in three theoretical areas of teaching Chinese to ethnic minority students were explored. Particularly, teachers increased their awareness of ethnic minority cultures, developed empathy with ethnic minority children and their families, gained knowledge of implementing culturally responsive teaching and meaningful and pleasurable learning of Chinese. The role of teacher sharing in effective professional development was highlighted.     

Attitudes toward Family Obligations among American Adolescents with Asian, Latin American, and European Backgrounds

This study was designed to examine the attitudes toward family obligations among over 800 American tenth ( M age = 15.7 years) and twelfth ( M age = 17.7 years) grade students from Filipino, Chinese, Mexican, Central and South American, and European backgrounds. Asian and Latin American adolescents possessed stronger values and greater expectations regarding their duty to assist, respect, and support their families than their peers with European backgrounds. These differences tended to be large and were consistent across the youths' generation, gender, family composition, and socioeconomic background. Whereas an emphasis on family obligations tended to be associated with more positive family and peer relationships and academic motivation, adolescents who indicated the strongest endorsement of their obligations tended to receive school grades just as low as or even lower than those with the weakest endorsement. There was no evidence, however, that the ethnic variations in attitudes produced meaningful group differences in the adolescents' development. These findings suggest that even within a society that emphasizes adolescent autonomy and independence, youths from families with collectivistic traditions retain their parents' familistic values and that these values do not have a negative impact upon their development.     

How Sustainable Are In‐service Teacher‐training Courses?

The present research addressed the issue of ‘life after a course’. The study aimed to evaluate the efficacy of four in‐service teacher‐training courses at the Hong Kong Institute of Education in terms of their usefulness and relevance to the teachers’ needs on return to school. An end‐of‐course evaluation questionnaire and a follow‐up questionnaire were sent six months after the courses to see if there were any significant differences in the participants’ views on the effectiveness of a course at two different time points. Qualitative data collected from interviews between the tutors and participants six months after the courses were also analysed to find out which aspects of the courses were considered to be most useful to the teachers on their return to school, and why they were useful. The findings from the research give valuable insights into the design of teacher‐education courses.     

Effect of Twinning on Chinese and English Vocabulary Knowledge

Vocabulary knowledge was tested in a native (Cantonese-Chinese) and foreign (English) language in 150 twins and 150 singletons aged 6–11 years, matched on age, gender, grade level, nonverbal intelligence, parents’ education, family income, and number of siblings and household members. The singletons clearly outperformed the twins on the native vocabulary, but this “twinning effect” was much less noticeable for the foreign vocabulary. The effect on English vocabulary was further reduced after exposure to English at home was controlled. Given that these participants learned most of their English in school rather than home, the present findings support the notion that the twinning effect is associated with increased competition for family interaction in twins compared with singletons.     

Mixing enhancement in microfluidic channel with a constriction under periodic electro-osmotic flow

We present a new approach to enhance mixing in T-type micromixers by introducing a constriction in the microchannel under periodic electro-osmotic flow. Two sinusoidal ac electric fields with 180° phase difference and similar dc bias are applied at the two inlets. The out of phase ac electric field induces oscillation of fluid interface at the junction of the two inlet channels and the constriction. Due to the constriction introduced at the junction, fluids from these two inlets form alternative plugs at the constricted channel. These plugs of fluids radiate downstream from the constriction into the large channel and form alternate thin crescent-shaped layers of fluids. These crescent-shaped layers of fluids increase tremendously the contact surface area between the two streams of fluid and thus enhance significantly the mixing efficiency. Experimental results and mixing mechanism analysis show that amplitude and frequency of the ac electric field and the length of the constriction govern the mixing efficiency.     

Release monitoring of single cells on a microfluidic device coupled with fluorescence microscopy and electrochemistry

A method for monitoring the biological exocytotic phenomena on a microfluidic system was proposed. A microfluidic device coupled with functionalities of fluorescence imaging and amperometric detection has been developed to enable the real-time monitoring of the exocytotic events. Exocytotic release of single SH-SY5Y neuroblastoma cells was studied. By staining the cells located on integrated microelectrodes with naphthalene-2,3-dicarboxaldehyde, punctuate fluorescence consistent with localization of neurotransmitters stored in vesicles was obtained. The stimulated exocytotic release was successfully observed at the surface of SH-SY5Y cells without refitting the commercial inverted fluorescence microscope. Spatially and temporally resolved exocytotic events from single cells on a microfluidic device were visualized in real time using fluorescence microscopy and were amperometrically recorded by the electrochemical system simultaneously. This coupled technique is simple and is hoped to provide new insights into the mechanisms responsible for the kinetics of exocytosis.     

Problem-based learning and the development of metacognition

This study samples first year undergraduates from two programmes at a Hong Kong University (N = 66). One programme uses an entirely problem-based approach to learning and teaching, whilst the other uses more traditional methods. Using the Learning and Study Strategies Inventory (LASSI) as a measure of student perceptions of their thinking, or metacognition it explores differences in metacognitive development between each group of students between the beginning and end of their first year in each programme. The paper argues that, in addition to the formal learning context, everyday challenges emerging from the additional new social contexts provided by problem-based curricula provide fertile environments for the development of metacognition because whilst the highest ‘meta-level’ of cognition is usually not implicated when we receive an outside task and when the task solution is known, the meta-level does tend to be consulted when things go wrong or when the situation is new. In other words, when we are faced with finding solutions to a problem whether posed by the teacher as part of a problem-based curriculum or a new social environment, we are more likely to develop generic, as well as subject specific skills.     

Teacher management and educational reforms: Paradigm shifts

In the past 15 years, numerous reforms and initiatives in many countries in the Asia-Pacific region have aimed to change education and promote new learning to prepare the new generation for the future. Unfortunately, despite good intentions and huge investments of resources, many of these reforms have been found to be ineffective and unsustainable—if they succeed at all. Reflecting on the trends and waves of educational reform in the Asia-Pacific region, this paper introduces an international lesson on the emerging syndrome of educational reform across the region and illustrates its negative impacts on teacher ecology and teacher management. Then, the paper outlines the implications of this lesson and of a study of the world’s best-performing educational systems, using them to develop a holistic approach to managing teachers and planning for their sustainable professional development. Finally, it highlights the paradigm shifts in teacher management, reviewing the three waves of educational reform in the last two decades, and draws further implications for formulating teacher management policies in ongoing and future educational reforms to support students’ new learning and sustainable development.     

Parental concerns regarding a centre-based early intervention programme for Down syndrome in Malaysia: a case study

This qualitative study provides information on the concerns faced by parents having children with Down syndrome in a centre-based Early Intervention Programme in Malaysia and how they coped with these concerns. Semi-structured interviews were conducted with a total of five parents and two special educators. The interview and observation findings indicate that there are numerous concerns faced by parents, such as the child’s uncertain future, teacher training, family involvement, expansion of services, support services, lack of information and resources, inconsistency of language used, increase in fees, and changes in lifestyle. The study has also revealed unmet needs of special children, for example, time duration, music therapy and the facilities provided. Recommendations have also been suggested for further needed improvement in the Early Intervention Programme.     

Issues of cultural appropriateness and pedagogical efficacy: exploring peer review in a second language writing class

This paper reports on a study designed to investigate (a) whether peer review is an effective pedagogical activity with adult Chinese students in the teaching of second language (L2) academic writing and (b) how factors such as perceptions of the influence of peer reviewers’ L2 proficiency, previous experience with peer review, feedback preferences, and culturally-based beliefs and practices relate to the effectiveness of the pedagogical activity. Participants were 20 English-as-an-L2 learners from China who were enrolled in an academic writing class for postgraduate students at a Singaporean university. Data included first drafts of an academic writing assignment, written peer comments, revised drafts of the assignment, responses to a questionnaire, and interviews. Quantitative analyses of the peer comments and revisions to the drafts show that significant improvement in the revised drafts was linked to peer feedback. Further statistical analyses indicate that the learner variables of interest did not affect the effectiveness of the peer review activity. In addition, qualitative analyses of the questionnaire data and the interviews reveal a general acceptance of peer review as a socioculturally appropriate pedagogical activity for Chinese students. The results of the study are interpreted with an understanding of its limitations, and directions for further research are also discussed.
