Local language a medium of instruction: challenges and way forward

The paper reports on a participatory action research study conducted in six rural primary schools in Uganda in 2013 to establish why children taught in the local language had difficulties in reading and writing. Findings through interviews, focus group discussions, reviews of exercise books and lesson observations indicated that though it was easier for pupils to learn the concepts in the local language; challenges ranging from poor translation, inadequate teachers’ language proficiency, lack of instructional materials, high pupils’ enrolment, lack of administrative support and teacher-centred approach of teaching, affected pupils’ learning to read and write. Participants recommended adopting the child-centred pedagogy, incorporating instructional materials, conducting continuous assessment and recording pupils’ competencies attained in reading and writing. Teachers need to engage more in Participatory action research in order to reflect on their practices and pupils’ learning, and collaboratively decide what works best and what needs improvement in their classrooms.

Globalization,values education,and school music education in China

This paper examines music education’s legitimation of values as a means of preparing students for entry into the new ‘knowledge society’ of the People’s Republic of China in a global age. It explores the ways in which values education relates to the teaching of both musical and non‐musical meanings in the dual context of nationalism and globalization, and discusses some problems that values education faces in school music classrooms. It examines the ways in which globalization has pressured values education into resolving the apparent contradiction between national identity and national unity in the ever‐changing play of Chinese history and politics. It concludes with a discussion of how music education might juggle three pairs of apparently contradictory relationships in the curriculum: between contemporary cultural and social values on the one hand, and traditional Chinese and Communist ideologies on the other; between collectivism and individualism; and between national and global cultures.     

Effect of language of instruction on physics achievement

This study investigated the relationship between physics achievement and language of instruction in a situation where instruction was in the second language of both students and teachers. One hundred and seventy-six grade ten physics students (first language was Chinese) were selected from four classes of two secondary schools in Hong Kong. For three months (with four lessons per week), two classes of students learned the content material (light and sound) in Chinese and two classes learned the material in English. Group differences were controlled by using individual aptitude scores as covariates in the analysis. There were no differences in achievement, students' motivation, and effort spent in physics in that controlled teaching period. This was probably because the Anglo-Chinese group was sufficiently proficient in English so they did not encounter additional difficulty in learning physics when compared with the Chinese group.

Bromo-oxidation reaction in enzyme-entrapped alginate hollow microfibers

In this article, the authors present the fabrication of an enzyme-entrapped alginate hollow fiber using a microfluidic device. Further use of enzyme-entrapped alginate hollow fibers as a biocatalytic microchemical reactor for chemical synthesis is also deliberated in this article. To ensure that there is no enzyme leaching from the fiber, fiber surfaces were coated with chitosan. To confine the mobility of reactants and products within the porous hollow fibers the entire fibers were embedded into a transparent polydimethylsiloxane (PDMS) matrix which also works as a support matrix. A vanadium-containing bromoperoxidase enzyme isolated from Corallina confusa was used as a model enzyme to demonstrate the use of these alginate hollow-fiber reactors in bromo-oxidation of phenol red to bromophenol blue at different dye flow rates. Stability of the entrapped enzyme at different temperatures and the effect of the chitosan coating on the reaction conversion were also studied. It was observed that molecules as big as 27 kDa can be retained in the matrix after coating with chitosan while molecules with molecular-weight of around 378 Da can still diffuse in and out of the matrix. The kinetic conversion rate in this microfluidic bioreactor was more than 41-fold faster when compared with the standard test-tube procedure.     

Chinese students at an English-Language university: Prediction of academic performance

There is a paucity of systematic research on prediction of success at the tertiary education level for Asian students, despite the important role that universities play in Asian communities, and despite the increasing numbers of such students who are coming to the West to study. This study reviews evidence collected over the past ten to fifteen years, which relates to the issue of prediction of academic performance of Chinese students at an English-Language and Western-oriented university - the University of Hong Kong. This review is complemented by an analysis of data collected longitudinally over a five year period, using multiple regression, multiple correlation, path analysis and canonical correlation analyses. The results provide evidence of factors which are important in determining the ability of a student to adapt to the foreign cultural and language barriers that exist at this university. In particular, ability in English language and mathematics provides good and reasonably independent predictors of success. The data show the importance of considering the cultural background of students when assessing their aptitude for study, and offer information for Western universities regarding their admissions procedures for Chinese students.     

An improvement on the transient response of tracking for the sampled-data system based on an improved PD-type iterative learning control

An improvement on the transient response of tracking for the sampled-data system based on an improved PD-type iterative learning control (ILC) is proposed in this paper. The developed analog ILC method and the high-gain property tracker design methodology are first combined to significantly reduce learning epochs and overcome the initial condition shift problem and discontinuous reference input in the traditional ILC. Besides, the proposed ILC improves the transient response and decreases the rate of weighting matrices Q$Q$ to R$R$ under the traditional linear quadratic tracker design. First, the off-line observer/Kalman filter identification (OKID) is used to determine the appropriate (low-) order system parameters and state estimator for the physical system with unknown system equation, so that the model-based PD-type ILC can be implemented for practical applications. Then, to improve the transient response and decrease the control effort, the proportional difference type (PD-type) ILC algorithm is combined with the high-gain property linear quadratic tracker (LQT) design to construct the high performance tracker for the model-based sampled-data systems. Furthermore, the discrete-time version high performance tracker design for the unknown stochastic sampled-data system via the iterative learning control method is proposed in this paper based on the Euler method and the digital redesign approach. Finally, some examples are given for illustrating the effectiveness of the proposed method.
