Assessing English vocabulary and enhancing young English as a Foreign Language (EFL) learners’ motivation through games,songs, and stories     

Mu-hsuan Chou 《Education 3-13》2013,41(3):284-297

In Taiwan, English was only officially taught at the secondary and tertiary levels before 2001. Since 2001, English courses have been formally incorporated into the curriculum in primary schools. Research on teaching and assessing English in primary school education is relatively new compared with research on other levels of education in Taiwan. The present study investigated the degree to which games, songs, and stories helped increase primary school pupils’ English vocabulary size and encouraged learning in an intensive English course. It also explored how different test techniques influenced pupils’ performance on a vocabulary test. Seventy-two primary school pupils participated in the study. The results showed that games, songs, and stories had a positive effect on learning and increasing the pupils’ English vocabulary. In the vocabulary test, the pupils in higher grades outperformed those in lower grades and performed differently in terms of test techniques.  相似文献   

稻纵卷叶螟自然种群平均生命表     

古德祥  周昌清  汤鉴球 《中山大学学报论丛》1989,(1)

1977至1982年在广东四会大沙区大田试验获得的27个生命表资料,按各年同一世代进行统计,平均得出:第2—6代由卵至成虫的存活率分别为9.07,1.39,0.02,0.48,0.17(%):死亡主要出现在卵和1,2龄幼虫阶段,死亡率达72～98%;种群增长指数(I)值2—6代分别为5.1705,0.8859,0.0129,0.2804和0.0845,第2代最高. 关键因素分析表明:1—2龄幼虫期,3—5龄幼虫期和蛹期的失踪对总K值的波动影响较大.相关回归分析回归系数1—2龄失踪为0.3450.3—5龄为0.3331,蛹为0.2602.因此,1—2龄和3—5龄失踪为关键因素,其次为蛹期失踪.  相似文献   

The Effect of Metacognitive Scaffolds on Low Achievers’ Laboratory Learning     

Sufen Chen  Chih-Chi Huang  Te-Lien Chou 《International Journal of Science and Mathematics Education》2016,14(2):281-296

This study explored the influence of experimental goal setting and planning on the attitudes toward science, self-efficacy, inquiry performance, and achievement of students with low academic performance. A total of 71 students aged 16–18 were randomly divided into a treatment group (with goal setting and planning) and a control group (without goal setting and planning). A microcomputer-based laboratory focused on Boyle’s Law, coupled with an inquiry worksheet, was assigned. Based on Winne and Hadwin’s model of self-regulated learning, scaffolding was offered to the treatment group to promote goal setting and planning. Data were collected from the worksheet, the Attitudes toward Science Scale, the Self-efficacy of Scientific Inquiry scale, and the Boyle’s Law Conceptual Test. The results showed that both the treatment and control groups improved significantly from the pre- to post-conceptual tests. In the treatment group, the male students gained significantly more conceptual knowledge than the female students. Regarding attitudes toward science, the male students’ scores on the post-test were higher than those of the females. It is concluded that the male students were more positive regarding goal setting and planning in the inquiry activity, whereas the female students did not benefit as much.  相似文献   

Predicting self-efficacy in test preparation: Gender,value, anxiety,test performance,and strategies     

Mu-Hsuan Chou 《The Journal of educational research》2019,112(1):61-71

Considerable evidence indicates that self-efficacy, task value, anxiety, and the use of language learning strategies are related. However, there is currently an insufficient understanding about their relations in high-stakes testing contexts. The author aimed to investigate how well social factors, test value, anxiety, test performance, and learning strategies predict high school students' self-efficacy in preparing for the English listening test as part of the University Entrance Examination in Taiwan. This research involved a large-scale questionnaire survey and a collection of students' English test scores. The participants were 636 students in Grade 12 of high school in Taiwan. A quantitative analysis of the questionnaire was conducted via hierarchical regression analysis. The results show that students' recent English test performance and test anxiety were two strong predictors of self-efficacy in preparing for the high-stakes test. In addition, resource management and metacognitive listening strategies had better predictive power over prior English level and test value.  相似文献   

Interactivity and interactive functions in web-based learning systems: a technical framework for designers     

Chien Chou 《British journal of educational technology : journal of the Council for Educational Technology》2003,34(3):265-279

The concept of interactivity and its implications for Web-based learning system design is re-examined. The author reviews the literature on the interactivity concept from the perspectives of communication, computer-assisted instruction, distance education, and interactive dimensions and functions for Web systems. A proposal is then made for a technical framework for including such dimensions and functions in Web-based learning systems. To enhance the framework's ease-of-use and overall effectiveness, each interactive function was submitted to two panels of experts for assessment and evaluation in terms of instructional necessity and programming difficulty. A discussion of the panels’ feedback and the potential for future research concludes the article.  相似文献   

Doing feminist difference differently: intersectional pedagogical practices in the context of the neoliberal diversity regime     

Sandra Smele  Rehanna Siew-Sarju  Elena Chou  Patricia Breton  Nicole Bernhardt 《Teaching in Higher Education》2017,22(6):690-704

At present there is a small, albeit growing, body of literature on pedagogical strategies and reflections which addresses the ways educators attempt to challenge the effects of neoliberalism on higher education. In this article, we reflect upon our pedagogical practices in higher education in this moment of neoliberal transformation wherein, as Sirma Bilge notes, intersectionality is being ‘undone’ in academic feminism. As graduate students teaching in Toronto, Canada, we describe how our commitment to social justice pedagogy works against this ‘undoing’ of intersectionality by embracing vulnerability, discomfort and the possibility of conflict in classrooms that do not simply accommodate, celebrate or include difference. Given that neoliberal renderings of diversity obscure and reinforce unequal relations of power, we demonstrate how we attend to these power relations, particularly racism which is salient to our teaching context, by employing intersectionality as a pedagogical practice and a political intervention to advance social justice.  相似文献   

阮籍的生存困境及其解脱方式     

张丑平 《洛阳师范学院学报》2002,21(6):61-63

阮籍是魏晋玄学人士中具有代表性的人物之一。他早年具有济世之志,但魏晋乱世并未给他提供实现理想的机会。在政治上,他处于一种失意状态。他企图用醉酒昏酣来摆脱这种生存困境,但终究无法解脱。强烈的孤独感、紧迫的时间感、命运的无常感又使他处于个体的生存困境之中。他想通过游仙、隐逸的方式来解脱,但最终还是失败。他的82首咏怀诗表现的正是他在生存困境中所产生的生命忧患感。  相似文献

Regional eigenvalue-clustering robustness of linear uncertain multivariable output feedback PID control systems     

Tung-Kuan Liu  Jyh-Horng Chou 《Journal of The Franklin Institute》2009,346(3):253-1704

This paper proposes a time domain approach to deal with the regional eigenvalue-clustering robustness analysis problem of linear uncertain multivariable output feedback proportional-integral-derivative (PID) control systems. The robust regional eigenvalue-clustering analysis problem of linear uncertain multivariable output feedback PID control systems is converted to the regional eigenvalue-clustering robustness analysis problem of linear uncertain singular systems with static output feedback controller. Based on some essential properties of matrix measures, a new sufficient condition is proposed for ensuring that the closed-loop singular system with both structured and mixed quadratically-coupled parameter uncertainties is regular and impulse-free, and has all its finite eigenvalues retained inside the same specified region as the nominal closed-loop singular system does. Two numerical examples are given to illustrate the application of the presented sufficient condition.  相似文献   

State space model identification of multirate processes with time-delay using the expectation maximization     

Ya Gu  Jicheng Liu  Xiangli Li  Yongxin Chou  Yan Ji 《Journal of The Franklin Institute》2019,356(3):1623-1639

This paper presents the problems of state space model identification of multirate processes with unknown time delay. The aim is to identify a multirate state space model to approximate the parameter-varying time-delay system. The identification problems are formulated under the framework of the expectation maximization algorithm. Through introducing two hidden variables, a new expectation maximization algorithm is derived to estimate the unknown model parameters and the time-delays simultaneously. The effectiveness of the proposed algorithm is validated by a simulation example.  相似文献
