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 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   

标准参照评估的行动实践 ——以香港中文大学通识教育基础课程为案例     

廖梁  王永雄  彭金满 《复旦教育论坛》2021,19(4):52-59

香港特别行政区高校从2015年开始，学生学业评估陆续由常模参照评估转为标准参照评估。本文以香港中文大学通识教育基础课程实施标准参照评估的行动为案例，分析了这项新的学业评估方式在实施中所遇到的问题，讨论了解决方法并提出实施模型。该模型包含评分量表的设计与开发、量表使用、教师意见反馈与量表修改，以及评分之后的集体讨论这一套实施流程。文章最后指出，要保证标准参照评估的有效实施，需建立教师实践共同体。实践共同体的行动包括：教师共同开发评估标准，通过集体讨论对评估标准的含义和使用达成共识，共同审视评估结果，根据评估结果进一步修改和完善评估标准。  相似文献

Microfluidic three-dimensional hydrodynamic flow focusing for the rapid protein concentration analysis     

Sungmin Hong  Pei-Hsiang Tsou  Chao-Kai Chou  Hirohito Yamaguchi  Chin B. Su  Mien-Chie Hung  Jun Kameoka 《Biomicrofluidics》2012,6(2)

A simple microfluidic 3D hydrodynamic flow focusing device has been developed and demonstrated quantitative determinations of quantum dot 525 with antibody (QD525-antibody) and hemagglutinin epitope tagged MAX (HA-MAX) protein concentrations. This device had a step depth cross junction structure at a hydrodynamic flow focusing point at which the analyte stream was flowed into a main detection channel and pinched not only horizontally but also vertically by two sheath streams. As a result, a triangular cross-sectional flow profile of the analyte stream was formed and the laser was focused on the top of the triangular shaped analyte stream. Since the detection volume was smaller than the radius of laser spot, a photon burst histogram showed Gaussian distribution, which was necessary for the quantitative analysis of protein concentration. By using this approach, a linear concentration curve of QD525-antibody down to 10 pM was demonstrated. In addition, the concentration of HA-MAX protein in HEK293 cell lysate was determined as 0.283 ± 0.015 nM. This approach requires for only 1 min determining protein concentration. As the best of our knowledge, this is the first time to determinate protein concentration by using single molecule detection techniques.  相似文献   

Hand-powered microfluidics: A membrane pump with a patient-to-chip syringe interface     

Max M. Gong  Brendan D. MacDonald  Trung Vu Nguyen  David Sinton 《Biomicrofluidics》2012,6(4)

In this paper, we present an on-chip hand-powered membrane pump using a robust patient-to-chip syringe interface. This approach enables safe sample collection, sample containment, integrated sharps disposal, high sample volume capacity, and controlled downstream flow with no electrical power requirements. Sample is manually injected into the device via a syringe and needle. The membrane pump inflates upon injection and subsequently deflates, delivering fluid to downstream components in a controlled manner. The device is fabricated from poly(methyl methacrylate) (PMMA) and silicone, using CO₂ laser micromachining, with a total material cost of ∼0.20 USD/device. We experimentally demonstrate pump performance for both deionized (DI) water and undiluted, anticoagulated mouse whole blood, and characterize the behavior with reference to a resistor-capacitor electrical circuit analogy. Downstream output of the membrane pump is regulated, and scaled, by connecting multiple pumps in parallel. In contrast to existing on-chip pumping mechanisms that typically have low volume capacity (∼5 μL) and sample volume throughput (∼1–10 μl/min), the membrane pump offers high volume capacity (up to 240 μl) and sample volume throughput (up to 125 μl/min).  相似文献   

Educational use of social networking technology in higher education     

Hsiu-Ting Hung 《Teaching in Higher Education》2013,18(6):703-714

This study explored how social networking technology can be used to supplement face-to-face courses as a means of enhancing students' sense of community and, thus, to promote classroom communities of practice in the context of higher education. Data were collected from 67 students who enrolled in four face-to-face courses at two public universities in Taiwan. Findings indicated that the majority of participants developed strong feelings of social connectedness and expressed favorable feelings regarding their learning experiences in the classes where social networking sites were used as a supplementary tool. Learner difficulties and concerns of instructors about the educational use of social media are addressed with recommendations for future research and practice.  相似文献
