How many heads are better than one? The reliability and validity of teenagers' self- and peer assessments
(Elsevier, 2010-02-01) Sung, Yao-Ting; Chang, Kuo-En; Chang, Tzyy-Hua; Yu,Wen-Cheng
Self- and peer assessments are becoming more popular in classrooms, but there are few data on the reliability and validity of such assessments performed by school children. Because these factors are greatly affected by the number of raters, we conducted two studies to determine the rating behaviours of teenagers in self- and peer assessments, and how the number of raters influences the reliability and validity of self- and peer assessments. The first study involved 116 seventh graders (the first grade of middle school), where students individually playing musical recorders were subject to self- and peer assessments. The second study involved 110 eighth graders, with Web pages constructed by students being subject to self- and peer assessments. Generalizability theory and criterion-related validity were used to obtain the reliability and validity coefficients of the self- and peer ratings. Analyses of variance were used to compare differences in self- and peer ratings between low- and high-achieving students. The coefficients of reliability and validity increased with the number of raters in both studies, reaching the acceptable levels of 0.80 and 0.70, respectively, with 3 or 4 raters in the first study (involving assessments of individual performance) and with 14–17 raters in the second study (involving assessments of group work). Furthermore, low- and high-achieving students tended to over- and underestimate the quality of their work in self-assessment, respectively. The discrepancy between the ratings of students and experts was higher in group-work assessments then in individual-work assessments. The results have both theoretical and practical implications for researchers and teachers.
What kinds of knowledge do teachers share on blogs? A quantitative content analysis of teachers' knowledge sharing on blogs
(Wiley-Blackwell, 2010-02-03) Hou, Huei-Tse; Chang, Kuo-En; Sung, Yao-Ting
The article focuses on a content analysis of the use of blogs in knowledge sharing by educators. It states that blog use for teachers' professional development may improve teacher interaction. It states that the coding scheme of the study utilized Bloom's taxonomy with a focus on the knowledge aspect of teacher discussions. It comments that teachers did not utilize blogs solely for professional development and suggests that unofficial environments might play a role in promoting a climate conducive of knowledge sharing. It also suggests the development of an automatic interaction analysis module could be used to detect current behavioral and content patterns and limitations in knowledge sharing by teachers, including automatic data mining.
Mobile-device-supported strategy for Chinese reading comprehension
(Routledge, 2010-02-01) Chang, Kuo-En; Lan, Yu-Ju; Chang, Chien-Mei; Sung, Yao-Ting
The work described in this paper explores the feasibility of using of a wireless handheld system (WHS) that supports the individual and co-operative reading activities of students and helps teachers implement reading strategy instruction in Chinese language classes. The experimental findings demonstrate that the WHS benefits students applying reading strategies and improves co-operative learning in relation to small reading groups.
Designing an electronic guidebook for learning engagement in a museum of history
(Elsevier, 2010-01-01) Sung, Yao-Ting; Chang, Kuo-En; Hou, Huei-Tse; Chen, Pin-Fu
Museums provide important avenues for lifelong learning, and using information and communication technology to maximize a museum’s lifelong learning potential is a recognized issue. This study proposed a human–computer–context interaction (HCCI) framework as a guide for designing a mobile electronic guidebook for a history museum. To fulfill the goals of the HCCI framework, two strategies, problem-based inquiry and historical-context-embedded visiting, were used to implement a HCCI guidebook. To evaluate the effects of the HCCI guidebook, this study conducted an experiment to compare three visiting modes: Visiting with the HCCI guidebook; visiting with a worksheet; and visiting without any supplementary tools. Sixty-two college students participated in the evaluation of the HCCI guidebook in the Tang dynasty tri-color glazed pottery exhibition at the National Museum of History. The results showed that the students with the HCCI guidebooks had, on average, a longer holding time with exhibits than either students with paper-based worksheets or students without supplementary materials. However, there were no significant differences in the knowledge gained about exhibits among the three modes.
Applying lag sequential analysis to detect visual behavioral patterns of online learning activities
(Wiley-Blackwell, 2010-03-01) Hou, Huei-Tse; Chang, Kuo-En; Sung, Yao-Ting
The article discusses how learners manage online learning behaviours such as active participation and interaction as well as the visual behavioural patterns used. These behavioural patterns could offer guidance for teachers to enhance student learning. Through an empirical observation and lag sequential analysis, which can examine whether or not the relationship between each behavior has been achieved, visual behavioural patterns of online learning activities was used. The visual pattern showed that the majority of students concentrated on browsing peers' works and answering questions.
