Is small actually big? The chaos of technological change     

Shih-Chang Hung  Min-Fen Tu 《Research Policy》2014

In this paper, we develop themes from complexity and chaos theory that help to explain the technological change process. We apply two quantifiers, correlation dimensions and Lyapunov exponents, to examine the signs and degrees of chaotic technological dynamics. To illustrate our ideas, we study the development of electronic displays from 1976 to 2010, using patent data. The results of the chaos model are matched against the profiles of patent citations. Our analysis contributes to the development of a chaotic model of technological change.  相似文献

Studying parental involvement and university access and choice: An ‘interacting multiple capitals’ model          下载免费PDF全文

Fang Gao  Jacky Chi Kit Ng 《British Educational Research Journal》2017,43(6):1206-1224

Capital‐embedded parental involvement in education is essential in enhancing university enrolment and maximising the educational potentials for equality and excellence. Previous studies in this field have mainly utilised Perna's ( 2000 , 2006 ) model, which defines parental involvement as social capital and identifies the additive influences of different types of capital (including social, economic and cultural capital) on university access and choice. Yet, little research to date theorises and disaggregates the interplay among various types of capital as well as the multiplicative capital effects on enrolment. This study addressed this gap. We proposed an ‘interacting multiple capitals’ (IMC) model and hypothesised that parental social capital could moderate the effects of cultural and economic capital on entry to university. To validate the model, a pilot survey was administered to 216 university students of Korean ethnicity in China and investigated the models of involvement adopted by Korean parents in the context of the increasing labour mobility of the Korean adult population. Moderated multiple regression analysis was employed and the results confirmed the hypothesis that capital effects upon university access and choice were multiplicative in nature, with social capital moderating the cultural capital influence on students’ educational aspirations. The study findings show that the interaction of various types of capital variables is sufficiently statistically significant to warrant future research and policy and practical discussion of how to promote parental involvement in university preparation and planning.  相似文献   

The views of Pasifika students in New Zealand about communicating mathematically     

Sashi Sharma  Jenny Young-Loveridge  Merilyn Taylor  Ngärewa Häwera 《Asia Pacific Journal of Education》2011,31(4):503-519

This paper focuses on the perspectives of Years 7 and 8 Pasifika students on mathematics learning, in particular their views about the communication of solution strategies with others (their peers), and their teacher. Pasifika students' ideas about the importance of communicating their mathematical reasoning and strategies to peers and teachers were analysed and themes identified. While most students were in agreement about the importance of explaining their thinking to others, there was considerable variation in the reasons they gave for their views. The findings are interpreted in relation to socio-cultural theory and recent writing about requirements for citizenship in the twenty-first century.  相似文献   

Exploring the characteristics of an optimal design of non-programming plugged learning for developing primary school students’ computational thinking in mathematics     

Wang  Jue  Zhang  Yi  Hung  Cheng-Yu  Wang  Qiyun  Zheng  Ying 《Educational technology research and development : ETR & D》2022,70(3):849-880

Existing computational thinking (CT) research focuses on programming in K-12 education; however, there are challenges in introducing it into the formal disciplines. Therefore, we propose the introduction of non-programming plugged learning in mathematics to develop students’ CT. The research and teaching teams collaborated to develop an instructional design for primary school students. The participants were 112 third- and fourth-grade students (aged 9–10) who took part in three rounds of experiments. In this paper, we present an iterative problem-solving process in design-based implementation research, focusing on the implementation issues that lead to the design principles in the mathematics classroom. The computational tasks, environment, tools, and practices were iteratively improved over three rounds to incorporate CT effectively into mathematics. Results from the CT questionnaire demonstrated that the new program could significantly improve students’ CT abilities and compound thinking. The results of the post-test revealed that CT, including the sub-dimensions of decomposition, algorithmic thinking, and problem-solving improved threefold compared to the pre-test between the three rounds, indicating that strengthened CT design enhanced CT perceptions. Similarly, the students’ and teacher’ interviews confirmed their positive experiences with CT. Based on empirical research, we summarize design characteristics from computational tasks, computational environment and tools, and computational practices and propose design principles. We demonstrate the potential of non-programming plugged learning for developing primary school students’ CT in mathematics.

A Comparative Investigation on the Learning Efficacy of Mechatronic Technology Between Academic and Vocational High School Students     

Min Jou  Chen-Kang Hung  Shih-Hung Lai 《Journal of Science Education and Technology》2014,23(6):777-783

Universities in Taiwan can be divided into two major categories of comprehensive universities and technological universities. Students studying engineering majors in comprehensive universities are often recruited from academic high schools while those in technological universities tend to be recruited from vocational high schools. The purpose of this research was to investigate differences in learning efficacy between college students with academic backgrounds and those with vocational backgrounds. Results indicated no significant differences in cognition between the two groups of students. Additionally, students with vocational school backgrounds performed better in comprehension skills compared with those with academic backgrounds and were more able to apply acquired knowledge to practical tasks according to path analysis studies and the Mann–Whitney U test.  相似文献   

The Home Literacy Environment and Preschool Children's Reading Skills and Interest     

Lay See Yeo  Winston W. Ong  Charis M. Ng 《Early education and development》2014,25(6):791-814

Research Findings: This study explored the association between the home literacy environment (HLE), conceptualized as comprising parents’ reading beliefs and home literacy practices, and preschoolers’ reading skills and reading interest. It also identified factors in the HLE that predict emerging reading competence and motivation to read. A total of 193 children age 6 years from 14 preschools across Singapore and their parents participated in the study. The parents completed a reading belief inventory, a family literacy activity inventory, and a demographic questionnaire that surveyed the child's reading interest. The children were administered a battery of standardized literacy tests. The study found a moderate relationship between the HLE and children's reading competencies and a strong relationship between the HLE and children's reading interest. When parents’ education level and children's age were controlled, hierarchical multiple regression analyses found that family literacy activities contributed more unique variance to children's reading outcomes and reading interest than did parents’ reading beliefs. Active parental involvement was the strongest component of the HLE, with parent–child engagement in reading and writing emerging as the best predictor of both the child's emerging reading skills and reading interest. With respect to reading beliefs, parents’ efficacy in supporting literacy development before their child attended school positively predicted reading competence, as did parents’ affect and verbal participation in fostering reading interest. However, verbal participation negatively predicted Singapore children's reading competence. Practice or Policy: The implications of the results were discussed.  相似文献   

The Effect on Enhancing Students＇ Inquiry Abilities via Step-by-Step Open-ended Inquiry Teaching Design     

Chung-Ming Yang  ;Jeng-Fung Hung  ;Tai-Chu Huang 《美中教育评论》2014,(12):887-894

The purpose of this study is to promote more open-ended inquiry activities in junior high school science lessons in the current educational system with fixed textbooks. Researchers adapted existing curriculum-based experimental activities for more open-ended inquiry ones. In addition, the whole class was provided with more opportunities to explore complete activities in limited teaching time. This study used Hazel＇s proposals of levels of inquiry. The method was to carry out the current 8th grade experiments through the step-by-step teaching material modification （from levels of inquiry 0 to 2b） and to combine the experimental teaching method with the 5E （engage, explore, explain, elaborate, and evaluate） learning cycle. After a quasi-experimental study, we compared the traditional teaching method with the step-by-step open-ended inquiry teaching one on 8th graders＇ basic and integrated science process skills and academic achievements. The study result showed that the academic achievement in the experimental group, based on the same instructional time, was not worse than that in the control group. No significant difference was found on the total scores of the basic science process skills between the two groups, but a significant difference was found on the ＂predicting＂ dimension. There was a significant difference on the total scores of the integrated science process skills between the two groups. Significant differences were found on ＂interpreting data＂ as well as ＂experiment designing＂ dimensions. Hence, the study indicated that it could enhance students＇ inquiry ability through step-by-step openly inquiry levels to change the existing curricula, which served as a reference of educational reform.  相似文献
