Schools in Singapore are now tasked to develop the spirit of innovation and enterprise in their students. This is in line with the national vision of ‘Thinking Schools, Learning Nation’. This policy initiative, which began in 2004, is set to change the fundamental nature of education in Singapore. This article discusses the innovation and enterprise (I&E) initiative, its major implications for schools in Singapore and the areas still to be addressed in the implementation of the policy. In particular, the article discusses the issues of teachers and school leaders as role models of I&E, I&E as an organic part of school business, the influence of the wider societal culture and values system, and the measurement of success of I&E. The challenge for schools is to go beyond the form of the initiative to bring real substantial and sustainable change through this movement. 相似文献

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel. 相似文献

In times of uncertainty, university faculties have a duty to prepare school leaders to handle complexity, as the number of variables in the educational system and the interactivity of variables increase exponentially. The Leaders in Education Program (LEP) is a 6-month full-time program at the Singapore National Institute of Education (NIE, which is a part of Nanyang Technological University). The LEP aims to prepare especially selected vice-principals and ministry officers in Singapore for school leadership. The LEP is a collaborative effort between the NIE and the Ministry of Education, an example of a university–government partnership in program development. This article describes the efforts of the LEP in developing the ability of school leaders to deal with complexity. It also examines in detail one particular component of the LEP, the Creative Action Project, to illustrate how this is done in practice, and analyzes the views of participants on their learning through the project. 相似文献

This paper describes how Singapore attempts to balance the need for quality assurance and the need for educational diversity
and innovation. The Singapore experience shows that this is a delicate balance. On the one hand, to promote diversity and
innovation, the government attempts to decentralise its power to the schools. On the other hand, for quality assurance, the
government sets up quality structures that reassert the centrality of government control. This paper examines the implications
of such a strategy and the challenges that schools face in navigating a new paradigm of diversity and innovation while satisfying
the requirements of quality assurance. 相似文献

This study examines the impact that secondary school studies have on university accounting courses. Multiple regression analysis has been used to determine the significance of various academic factors. Secondary school accounting and mathematics were found to have far greater effectiveness in predicting results in the initial university accounting course than did other variables, but this benefit diminished in the second year and vanished in the third year of the accounting programme. 相似文献

This paper presents the findings of an action research that examines teachers' perception of the quality of dialogue and how
it impacts on the quality of relationships in a primary school in Singapore. The paper explores how school leaders can facilitate
dialogue and also discusses the issues and factors that affect teachers' perception of dialogue. Analysis of the data obtained
through a questionnaire and face-to-face interviews shows that the more favourable the perception of dialogue amongst teachers,
the more favourable is their perception of the quality of relationships in the school. The implication for school leaders
is that by developing a higher quality of dialogue, a better school climate is fostered.
