Computer-based collaborative problem-solving assessment in Taiwan

Abstract

The current study explores students’ collaboration and problem solving (CPS) abilities using a human-to-agent (H-A) computer-based collaborative problem solving assessment. Five CPS assessment units with 76 conversation-based items were constructed using the PISA 2015 CPS framework. In the experiment, 53,855 ninth and tenth graders in Taiwan were recruited, and a multidimensional item response analysis was used to develop CPS scales and represent the students’ collaboration and problem solving performance. The results show that the developed H-A approach is feasible for measuring students’ CPS skills, and the CPS scales are also shown to be reliable. In addition, the students’ CPS performance scores are further explored and discussed under the PISA CPS framework.     

从东京大学的发展看日本政府对高等教育的态度

东京大学是日本历史最悠久、规模最大的国立大学,是日本政府为了与欧美强国抗衡而建立的综合性大学,它在其发展的各个时期都对国家和民族的发展有重要贡献。从东京大学成立之日起,日本政府就对它寄予厚望,给予种种优待,以此为基础,东京大学日益发展,成为世界著名的高等学府。从日本政府对待东京大学的态度,可以窥见其对待高等教育的态度。     

Effects of multimedia on cognitive load, self-efficacy, and multiple rule-based problem solving

This study investigates effects of multimedia on cognitive load, self-efficacy and learners' ability to solve multiple rule-based problems. Two hundred twenty-two college students were randomly assigned to interactive and non-interactive multimedia groups. Based on Engelkamp's multimodal theory, the present study investigates the role of multimedia in multiple rule-based problem solving. The findings indicate that providing learners with manipulative function in multimedia would facilitate their problem solving through reduced cognitive load and improved self-efficacy. The study identifies a significant mediator effect for self-efficacy that mediates between multimedia and learners' problem solving. Discussion focuses on the effects of multimedia and self-efficacy on learners' performance in multiple rule-based problem solving. Suggestions are made with regard to the design of problem solving in future studies.     

The comparative efficacy of two approaches to teaching sixth graders opinion essay writing

Children in sixth grade randomly assigned to a teacher-made writing procedure anchored in the self-regulated strategy development (SRSD) model and training procedures were predicted to surpass children assigned to the comparison condition on dependent measures of writing clarity, organization, and cogency. The prediction was generally substantiated. The results suggest that the rate of change among individual children in the SRSD condition was faster than among children in the comparison condition on measures of clarity and organization. On the measure of cogency, findings showed that the rate of change among individuals in the SRSD condition compared to the comparison condition approached but did not reach statistical significance. Variance in growth parameters on the measure of writing clarity was statistically significant; however on the measure of organization, there was no substantive variation in individual growth parameters. Social validity data from all the children and teachers indicated the training was well received. The results are taken to support the efficacy of the SRSD model and training procedures.

A comprehensive update: gastrointestinal microflora,gastric cancer and gastric premalignant condition,and intervention by traditional Chinese medicine

With the recent upsurge of studies in the field of microbiology,we have learned more about the complexity of the gastrointestinal microecosystem.More than 30 genera and 1000 species of gastrointestinal microflora have been found.The structure of the normal microflora is relatively stable,and is in an interdependent and restricted dynamic equilibrium with the body.In recent years,studies have shown that there is a potential relationship between gastrointestinal microflora imbalance and gastric cancer(GC)and precancerous lesions.So,restoring the balance of gastrointestinal microflora is of great significance.Moreover,intervention in gastric premalignant condition(GPC),also known as precancerous lesion of gastric cancer(PLGC),has been the focus of current clinical studies.The holistic view of traditional Chinese medicine(TCM)is consistent with the microecology concept,and oral TCM can play a two-way regulatory role directly with the microflora in the digestive tract,restoring the homeostasis of gastrointestinal microflora to prevent canceration.However,large gaps in knowledge remain to be addressed.This review aims to provide new ideas and a reference for clinical practice.     

The effects of visual and verbal coding mnemonics on learning Chinese characters in computer-based instruction

The effects of different approaches to learning Chinese characters were investigated. Ninety-two high-school students were randomly assigned to one of five treatment groups: translation, verbal mnemonics, visual mnemonics, dual coding mnemonics, or self-generated mnemonics. All groups received instruction and completed posttests in a computer-based environment. The results indicate that participants who generated their own mnemonics demonstrated higher posttest performance than those in visual coding, verbal coding, and translation groups; subjects in the dual coding group scored higher than those in the translation group. Those who generated their own mnemonics spent more time on task than any other group, and those in the verbal coding group took more time than those in the translation group. Survey and qualitative data suggest that learners' interpretations of the Chinese characters were rooted in their cultural backgrounds and personal experiences.
