Changing the English language curriculum in Brunei Darussalam

This paper describes the development of a language project in Brunei Darussalam, a project aimed at improving English language learning and fostering positive reading interests. In-service teachers were trained to change from traditional textbook-based techniques to an activity-based approach integrating the practice of aural-oral and writing skills. The major components of project implementation will be discussed to demonstrate the optimization of available resources, particularly available expertise in teacher skill and language competence. This project provides an interesting example of an attempt to satisfy the practical demands of policy-makers while adhering to research standards of evaluation studies.     

Health benefits of Kung Fu: A systematic review

Abstract

The Chinese martial arts (Kung Fu) have existed for centuries and are generally accepted as being beneficial for health without much empirical data. The aim of this systematic review was to assess the health effects of “hard” Kung Fu styles by performing electronic and manual searches of the literature. The aspects of health and the Kung Fu style examined varied between most studies; in some cases, the martial art group consisted of practitioners of other martial art styles also. Of 2103 references identified, only nine papers were eligible and reviewed. All were observational studies, observing a range of health aspects possibly related to Kung Fu training or performance. Our findings suggest that there is no evidence that Kung Fu practice is associated with the prevention or treatment of any health condition. However, as a moderate- to high-intensity form of aerobic exercise, it may confer benefits similar to those attributed to other aerobic training modalities. However, this hypothesis remains to be tested in clinical trials. Physiological benefits (e.g., aerobic capacity and bone density) may be associated with long-term Kung Fu practice. Future research in this area should adopt experimental designs, clearly identifying eligibility criteria, testing and training protocols, and include health-related outcomes and documentation of adverse events, to advance knowledge in this field.     

Anti-adipogenic effects of extracts of Ficus deltoidea var. deltoidea and var. angustifolia on 3T3-L1 adipocytes简

Objective

This study examined the anti-adipogenic effects of extracts of Ficus deltoidea var. deltoidia and var. angustifolia, a natural slimming aid, on 3T3-L1 adipocytes.

Methods

Methanol and water extracts of leaves of the F. deltoidea varieties were analyzed to determine their total flavonoid content (TFC) and total phenolic content (TPC), respectively. The study was initiated by determining the maximum non-toxic dose (MNTD) of the methanol and water extracts for 3T3-L1 preadipocytes. Possible anti-adipogenic effects were then examined by treating 2-d post confluent 3T3-L1 preadipocytes with either methanol extract or water extract at MNTD and half MNTD (1/2MNTD), after which the preadipocytces were induced to form mature adipocytes. Visualisation and quantification of lipid content in mature adipocytes were carried out through oil red O staining and measurement of optical density (OD) at 520 nm, respectively.

Results

The TFCs of the methanol extracts were 1.36 and 1.97 g quercetin equivalents (QE)/100 g dry weight (DW), while the TPCs of the water extracts were 5.61 and 2.73 g gallic acid equivalents (GAE)/100 g DW for var. deltoidea and var. angustilofia, respectively. The MNTDs determined for methanol and water extracts were (300.0±28.3) and (225.0±21.2) μg/ml, respectively, for var. deltoidea, while much lower MNTDs [(60.0±2.0) μg/ml for methanol extracts and (8.0±1.0) μg/ml for water extracts] were recorded for var. angustifolia. Studies revealed that the methanol extracts of both varieties and the water extracts of var. angustifolia at either MNTD or 1/2MNTD significantly inhibited the maturation of preadipocytes. Conclusions: The inhibition of the formation of mature adipocytes indicated that leaf extracts of F. deltoidea could have potential anti-obesity effects.     

金钱榕提取物抑制3T3-L1脂肪细胞抗脂肪沉积研究(英文)

研究目的:对两个品种金钱榕(var.deltoidea和var.angustifolia)叶片提取物抑制3T3-L1脂肪细胞脂肪沉积进行研究,为基于金钱榕的抗肥胖功能产品开发提供理论基础。研究方法:用甲醇和水分别对两个品种金钱榕的叶片进行提取,并分别分析了提取物中的总黄酮含量(TFC)和总酚含量(TPC)。通过MTT法确定提取物对3T3-L1脂肪细胞的最大无毒剂量(MNTD)。然后,通过油红O染色和吸光度测定来定性和定量研究提取物对抗脂肪细胞脂肪沉积的作用。重要结论:金钱榕两个品种deltoidea和angustifolia的甲醇提取物中的TFC含量分别为1.36和1.97 g QE/100 g DW,水提取物中的TPC含量分别为5.61和2.73 g GAE/100 g DW。金钱榕deltoidea品种的甲醇和水提取物对3T3-L1细胞的MNTD分别为(300.0±28.3)和(225.0±21.2)μg/ml,而angustifolia品种的MNTDs则较低(其甲醇和水提取物的MNTDs分别为(60.0±2.0)和(8.0±1.0)μg/ml)。金钱榕两个品种的甲醇提取物和angustifolia品种的水提取物在MNTD或1/2MNTD的浓度下,均具有显著抑制前脂肪细胞的成熟的作用。因此,根据其抑制成熟脂肪细胞形成的结果可以得出金钱榕叶片提取物具有潜在的抗肥胖效果。     

The (bio)politics of engagement: shifts in Singapore's policy and public discourse on civics education

This article provides a historical overview of civic educational policy and political discourse in Singapore from 1959 to 2011, focusing on changes in the role attributed to students in the education process. A review of educational programmes and analysis of political speeches reveals that an earlier transmissionist approach that focused on value inculcation and factual knowledge has been supplemented recently by policy and discourse emphasizing student engagement. The authors link their analysis to larger political changes that have been taking place in Singapore. They argue that the push for more participatory forms of civics education parallels an ongoing shift in the ruling party's political ideology from economic pragmatism to a communitarian ideology that emphasizes citizens' responsibility. From the point of view of political rationality, promoting active student engagement in civics education can be seen as governmental efforts to build a strong civil society through early socialization into civic responsibility and voluntarism. Viewed as a technology of power, engagement is also seen as a new biopolitical intervention aimed at regulating political participation.     

Reading Acquisition in Singapore

One of Singapore's problems with reading acquisition programmes stems from the fact that although most of our children come from non-Englisg speaking homes, their parents' choice of the medium of instruction is English. This means that English is taught right from the first day the child enters school. Most of the other countries where English is taught and is not the mother tongue, use the mother tongue as a medium of instruction for several years before the introduction of English. Neither are Singaporean children totally immersed in English at school because they also spend part of their school time learning a non-English language, namely Chinese, Malay or Tamil. Investigation into problems connected with the teaching of English and reading is therefore very important for Singapore, especially since one of our education system's streaming procedures is instituted very early, at the end of the third year of schooling at Primary 3.

Reading Instruction in Lower Primary Classes: A Second Observational Study

1985 marked the beginning of the implementation of the Reading and English Acquisition Programme (REAP)—a programme aimed at retraining lower primary English teachers in reading and English language instruction. This programme covering 90 schools in 1986 evolved from research conducted by the Institute of Education personnel. The Reading Skills Project (see Ng, 1984), a 3-year study, examined pupils' reading progress from Primary 1 to 3 in 35 schools; a teacher-observation study looked into reading instructional activities in 24 of the above schools. There was simultaneously a search for reading instruction approaches suitable for the Singapore classroom followed by a small feasibility survey on a chosen approach; a re-examination of in-service reading courses and a literature search for strategies for programme implementation. The present study attempts to discuss only the teacher-observation facet of the total research work behind REAP. In view of the fact that Singapore-based teacher-observation studies are few (see Evaluation of CLIPS, 1981) and studies on the teaching of reading in lower primary still fewer (see Ng, 1980), it is important to first record the research findings for the study done in 1984, and their implications for classroom practice. As this study both replicates and extends a similar study done earlier, teacher educators and educational authorities may find, from the accumulated experience, confirming evidence of directions for a retraining programme for reading teachers, and the urgent need for both curriculum and instructional change in this field.
