This study investigated whether enrichment activities would improve achievement in science.
One hundred and eighty subjects took part in the study. They were assigned to two experimental, two control and one Hawthorne control groups. Experimental subjects participated in enrichment activities held outside the school. Control subjects were not given these activities while the Hawthorne control group was taken out on excursions unrelated to their science lessons.
The Cooperative Science Test (COST) was used to assess the acquisition of science concepts while science achievement was based mainly on school science examination scores.
The results indicated that the experimental subjects showed significantly greater improvement in concept attainment and science achievement. Correlations between science concept attainment and science examination scores were positive and significant.
The study concluded that participation in enrichment activities relevant to school science would improve science achievement. 相似文献

In facing up to the challenges and impacts of globalization, high technology, economic transformation, international competitions
and local developments in the new century, there have been numerous educational reforms and initiatives in many countries
in the Asia-Pacific Region (Cheng, 2005a, A new paradigm for re-engineering education : Globalization, localization and individulization.
Dordrecht, The Netherlands: Springer). Unfortunately, many of these educational reforms with good intentions and huge resources
investment have been found ineffective and unsustainable if not totally failed. One of the major reasons for this is lack
of a comprehensive knowledge base for policy development and implementation supported by sophisticated and relevant educational
research.
From the waves and trends of educational reforms in the Asia-Pacific Region, this article aims to draw implications for future
developments of educational research in supporting paradigm shifts, policy formulation, and practice of educational reforms
in the Region and other parts of the world in an era of globalization and transformation.
This article was adapted from the president address at the International Conference of Asia-Pacific Educational Research Association
held on 28–30 November 2006, Hong Kong. 相似文献

Curriculum reform with a school-based approach is often assumed to offer schools and teachers autonomy at the site level, thus enabling them to develop a school-based curriculum and pedagogies to better fit the needs of students. Over the past decade, school-based curriculum development in Hong Kong has encountered issues that deserve worldwide attention and discussion. By reviewing the experiences of two schools in Hong Kong and drawing on international evidence, this study identifies key challenges and difficulties in school-based curriculum reform in three areas. Intellectually, there is a lack of a strong and broad shared knowledge base for curriculum development. As a result, most school-based curriculum initiatives have been piecemeal, fragmented and shallow. Structurally, many teachers have wasted time ‘re-inventing the wheel’ when developing school-based curricula. This effort has left them without sufficient time and energy to be effective in teaching. Culturally, reliance on school management to steer school-based reforms has prevented the development of a new culture in which teachers have the autonomy to make changes in their daily practices. Without cultural changes, curriculum reforms are not sustainable or effective. This study proposes a cooperative platform that integrates the strengths of central intelligence and school-based initiatives to maximise support for curriculum development at the teacher, school-site and system levels. 相似文献

This article briefly describes the Hong Kong education system, discusses the policies and efforts for education quality and school improvement, and reviews the development of school effectiveness research in Hong Kong. Hong Kong people have shown their strong commitment to educational reform for better societal development in the coming decades. A number of important policies have been issued to improve educational practice and school management. Even though some drawbacks and difficulties have inevitably been encountered in policy formulation and implementation, numerous good opportunities have been created for policy-makers, school practitioners, and educational researchers to conduct educational innovation, school improvement, and school effectiveness research. The ongoing education experiments, reform experiences, improvement practices, and effectiveness studies at both the system and school levels may not only benefit Hong Kong people but also make a contribution to international concern for school effectiveness and improvement. 相似文献

The success of any open and distance learning course depends on how well it is designed, executed, and evaluated. Evaluation of a course not only demonstrates its strengths, but also points out any inherent shortcomings in the course. This is why course evaluation constitutes an important function in an open and distance learning system. The present paper aims to evaluate a distance education course ‘Instruction in higher education’ from the Postgraduate Diploma in Higher Education (PGDHE) offered by the Indira Gandhi National Open University (IGNOU), India. Feedback on this course was obtained from 230 respondents with the help of a structured questionnaire. The data collected from students were analysed using percentages. Findings from the study provide an understanding of the operation of the different components of the course. While the majority of the respondents were satisfied with self‐instructional materials, assignments, the extended contact programme, and delivery mechanisms, a sizeable number of respondents were dissatisfied with academic counselling, and the use of audio‐video programmes. Generally, the respondents provided useful feedback and suggestions which will help the faculty in course revision. 相似文献

This study aims to investigate how principal's leadership is related to school performance in terms of multi‐level indicators such as school's organizational characteristics, teachers’ group‐level and individual‐level performances, and students’ performances. In the study, strong leadership represents that a principal can be supportive and foster participation for teachers, can develop clear goals and policies and hold people accountable for results, can be persuasive at building alliances and solving conflicts, can be inspirational and charismatic, and can encourage professional development and teaching improvement. The strong leadership is found associated with high organizational effectiveness, strong organizational culture, positive principal‐teachers relationship, more participation in decision, high teacher esprit and professionalism, less teacher disengagement and hindrance, more teacher job satisfaction and commitment, and more positive student performance particularly on attitudes to their schools and learning. The findings support that principal's leadership is a critical factor for school performance at multi‐levels. Implications are advanced for further study and development of leadership. 相似文献

This paper presents a numerical study of DC-biased AC-electrokinetic (DC-biased ACEK) flow over a pair of symmetrical electrodes. The flow mechanism is based on a transverse conductivity gradient created through incipient Faradaic reactions occurring at the electrodes when a DC-bias is applied. The DC biased AC electric field acting on this gradient generates a fluid flow in the form of vortexes. To understand more in depth the DC-biased ACEK flow mechanism, a phenomenological model is developed to study the effects of voltage, conductivity ratio, channel width, depth, and aspect ratio on the induced flow characteristics. It was found that flow velocity on the order of mm/s can be produced at higher voltage and conductivity ratio. Such rapid flow velocity is one of the highest reported in microsystems technology using electrokinetics. 相似文献

This paper reports on the understanding of three key conceptual categories relating to the kinetic particle theory: (1) intermolecular
spacing in solids, liquids and gases, (2) changes of state and intermolecular forces and (3) diffusion in liquids and gases,
amongst 148 high school students from Brunei, Australia, Hong Kong and Singapore using 11 multiple-choice items that required
students to provide explanations for their selection of particular responses to the items. Students’ responses to the items
revealed limited understanding of the particle theory concepts, with nine alternative conceptions held by more than 10% of
various samples of students. Also, 40.5–78.4% of all students indicated consistent understanding relating to the three conceptual
categories based on their responses to the 11 items. However, when their explanations were taken into account, very few students
displayed consistent understanding of the related concepts. 相似文献

This study examines the prevalence, contexts, and demographic correlates of monotonic response patterns (MRPs) in online student evaluations. Results of two-level hierarchical generalized linear models show evidence of careless monotonic responses to a survey administered to students enrolled in a university-level foreign language course in the Republic of Korea. All else being equal, freshmen and students in classes with fewer survey participants were more likely to choose monotonic response patterns in course evaluations. Possible factors at work in generating MRPs are identified and discussed. The severity of the MRP problem in online ratings underscores the importance for administrators to consider possible validity threats in student evaluations before using them as tools to inform instructional and administrative decisions. It is also important to design course evaluation surveys in such a way as to minimize careless responses and to identify means to induce more thoughtful responses from college students. 相似文献
