Research Report RECSAM: Computers in Education Project,Singapore Study

From 1986 to 1988, Regional Centre for Education in Science and Mathematics (RECSAM) at Penang organised the Computers in Education Project with financial support from the Australian Government. The aim of the Project was to provide information on the use of computers in education among SEAMEO countries. Such information, it was thought, could be useful for educators who needed to formulate sound policies regarding the introduction, management, and use of computers in schools and the roles of computers in education in general. Six countries took part in this project including a team from Singapore.     

Scaling up of Continual Professional Development for Mathematics Problem Solving in Singapore Schools

The more ambitious an educational innovation, the greater the challenge in scaling up. In this paper, we focus on the scaling up of an ambitious pedagogical practice—mathematics problem solving as a regular feature in the classroom. We adopt a long-term approach to continual professional development (CPD) that began with intensive work with one school before we broadened the programme to four other schools which span the spectrum of schools in Singapore. To evaluate this overall design, we examine the current state of each school’s capacity in sustaining mathematics problem-solving instruction. In particular, we study and report findings on these areas: the readiness of teachers, the instructional materials and supporting structures. Based on the findings, we reflect on our CPD strategies and our theory of action which guided the CPD programme.

2010我国上市公司治理评价体系研究

我国上市公司治理机制具有动态性的特征。公司治理评价体系需要随公司治理环境的改变而调整。基于2010年公司治理的调查数据,经验性的研究表明,我国上市公司治理机制在整体上处于良好的运营状态,而股权结构非均衡性、中小股东控制权缺失与财务透明性不足仍然是阻碍治理机制优化的显著性因素。     

Redesigning problem-based learning in the knowledge creation paradigm for school science learning

The introduction of problem-based learning into K-12 science classrooms faces the challenge of achieving the dual goal of learning science content and developing problem-solving skills. To overcome this content-process tension in science classrooms, we employed the knowledge-creation approach as a boundary object between the two seemingly contradicting activities: learning of science content and developing problem-solving skills. As part of a design research, we studied a group of Grade 9 students who were solving a problem related to the Law of Conservation of Energy. Through the lens of the activity theory, we found that students’ understanding of the intended science knowledge deepened as they made sense of the disciplinary-content knowledge in the context of the problem and concurrently, the students successfully developed solutions for the problem. This study shows that developing problem-solving competencies and content learning need not be disparate activities. On the contrary, we can harness the interdependency of these two activities to achieve dual goals in learning.     

Styles of creativity: Adaptors and innovators in a singapore context

Kirton (1976) described two creative styles, namely adaptors and innovators. Adaptors prefer to “do things better ” whilst, innovators prefer to “do things differently ”. This study explored the relationship between two creative styles (adaptor and innovator) and the Big Five personality traits (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience) and how they subscribe to creativity, risks and goal orientations. A total of 206 Polytechnic students from Singapore completed a self-report questionnaire, which consisted of the Kirton Adaptation-Innovation Inventory (Kirton, 1976), NEO-Five Factor Inventory (Saucier, 1994), Learning Goal Scale (Ng, 2003), What Kind of Person Are You Self-Report Inventory (Khatena & Torrance, 1976), Gough’s Creative Adjective Checklist, Risk Scenario, and Risk Taking Attitude Scale developed by Ng. It was found that adaptors were significantly more conscientious and subscribe to risk avoidance, ego approach and ego avoidance orientations than innovators, whilst, innovators were significantly more extraverted and open to experience and are likely to subscribe to creativity, risk taking and mastery goal orientations than adaptors. No significant differences were found between adaptors and innovators in agreeableness. The implications for the findings for the classroom teacher will also be discussed.     

Trait procrastination,self-efficacy and achievement goals: the mediation role of boredom coping strategies

Limited research has examined the mediational role of coping strategy in students’ motivation and procrastination. In this study, we examined the relationships among self-efficacy, achievement goals, boredom coping strategies and procrastination with 506 Chinese college students. Data were collected via questionnaires. Structural equation modelling results showed that both self-efficacy and approach goals significantly predicted approach-oriented coping strategies, and avoidance goals significantly predicted avoidance-oriented coping strategies. Among the different types of boredom coping strategies, only behavioural avoidance coping strategy significantly predicted procrastination. Hence, the mediating link was only found between avoidance goals, behavioural avoidance coping strategy and procrastination. Implications of the mediating role of behavioural avoidance coping strategy in the goal-procrastination relationship were further discussed.
