Solving ill-structured problems in asynchronous online discussions: built-in scaffolds vs. no scaffolds     

Connie Siew Ling Ng  Wing Sum Cheung  Khe Foon Hew 《Interactive Learning Environments》2013,21(2):115-134

Solving ill-structured problems is regarded as an important learning outcome in education as it allows learners to apply theories learnt into real practice. An asynchronous online discussion, with extended time for reflection, is an appropriate learning environment to engage learners in solving ill-structured problems. However, scaffolds may be needed to support learners in the online discussions. This study explores the effect of online scaffolds in supporting a group of graduate students' ill-structured problem-solving processes in asynchronous online discussions. The results of this study showed that the use of the online scaffolds did not lead to a significant difference in the number of ill-structured problem-solving processes. Further analysis revealed that wrong selection of message labels and under-usage of sentence openers affected the results of this study. Improvements for online scaffolds include having more precise message labels and sentence openers based on Socratic questioning approach.  相似文献   

Teacher Evaluation and Effectiveness in Hong Kong: Issues and Challenges     

John Chi Kin Lee  Wing Po Lam  Yuk Yung Li 《Journal of Personnel Evaluation in Education》2003,17(1):41-65

This article first provides an overview of teacher effectiveness and evaluation in Hong Kong. Several studies related to classroom environment and teacher behavior in selected subjects are referenced, as are recent studies of teachers instructional leadership. Finally, the preliminary use of the Revised Classroom Observation Instrument (RCOI) from the Louisiana School Effectiveness Study in three secondary schools is reported. The results from using the RCOI in Hong Kong indicate that some items may be irrelevant in the Hong Kong context (e.g., physical characteristics), while more items may be needed to reflect good teaching in Hong Kong (e.g., questioning skills). In addition, the potential use of teacher profiles to drive staff development and school improvement is explored.  相似文献   

年底DV大看点——索尼意外急降 佳能高调上市

每年岁尾，都是本年度最后一批新机上市的时节．这批新上市的机器一般都是在9月-10才发布的．而且基本上都是面向高端市场．今年也不例外。新机上市是市场的规律所在，而因此造成某些机型降价也是正常的．不过近期有点意外的是在松下、佳能、JVC都推出05年最高端机型的时候．  相似文献

Examining students’ affective commitment toward country: a case study of a Singapore primary school     

Khe Foon Hew  Wing Sum Cheung 《Asia Pacific Journal of Education》2011,31(1):19-31

The purpose of this study was to examine students’ affective commitment toward Singapore. Affective commitment refers to the sense of attachment to the nation state. The sample was taken from 286 students in a primary school. In the first section of the paper, we described the design of a Likert-type Affective Commitment to Country questionnaire. Factor analyses (principal component analysis and confirmatory factor analysis) showed evidence of construct validity for the 10-item scale, and an overall Cronbach alpha reliability coefficient of 0.91. In the second section, we reported the statistics related to the students’ affective commitment scores. Overall, a positive affective commitment toward the country was found. Results of our t-test analyses revealed that no statistically significant difference was found between boys and girls for each of the questionnaire items. However, students who had higher academic achievement reported significantly higher scores than their lower ability counterparts with regard to six items of the questionnaire. Suggestions for future research are discussed.  相似文献   

Classroom climate and students’ goal structures in high-school biology classrooms in Kenya     

Winnie Mucherah 《Learning Environments Research》2008,11(1):63-81

This study examined classroom climate and student goal structures in high-school biology classrooms in Kenya. Participants included 891 students and their teachers in Grades 10 and 11 from two same-sex boarding schools—one for boys and the other for girls. School differences were found on all classroom climate aspects except teacher support and competition. Relative to tenth graders, eleventh graders perceived their classrooms to be higher in teacher support, task focus, competition, rule strictness, and innovation. There were school and grade differences in students’ goal structures, with School 1 students, relative to School 2 students, perceiving more personal performance-approach goals and their teachers as encouraging performance-approach goals. Eleventh graders reported more performance-approach goals at both the personal and teacher levels. Teachers perceived their classroom climates more positively than their students. Observation data provides interpretative information.  相似文献   

Enhancing orthographic knowledge helps spelling production in eight-year-old Chinese children at risk for dyslexia     

Leong CK  Loh KY  Ki WW  Tse SK 《Annals of dyslexia》2011,61(1):136-160

We investigated the effects of enhancing orthographic knowledge on the spelling of Chinese characters and words in 131 eight-year-old Chinese children at risk for dyslexia. The traditional approach (37 children) emphasizing memory and repeated writing was the control condition. The analytic and synthetic approach (ASA, 33 children) stressed insight into character structure. The integrated analytic and synthetic approach added to ASA self-correction and metacognitive activities (INA, 61 children). The children were first asked to write down as many words as possible associated with pictures of home, school, and community; the correctly written words formed the baseline information. The children were then instructed by their classroom teachers in six especially designed short texts and assessed in eight measurable bujian or radical tasks subserving three constructs: morpheme completion, bujian analysis and synthesis and bujian compounding. Multivariate analyses of variance showed that the children in the INA condition outperformed those in the other conditions in three of the measurable bujian tasks. A confirmatory factor analysis verified the stability of the eight tasks and their clustering into three constructs. From these results, we tentatively propose a “bujian sensitivity hypothesis” as a means of helping young Chinese children at risk for spelling disorders.  相似文献
