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.

Practice makes better? A study of meditation learners in a classroom environment

The study investigates the effect of length of meditation history on various factors, namely learning motivation, learning outcome and classroom climate. Data were collected from working adult learners (n = 450) attending meditation classes in two large cities in Taiwan. The investigation categorized learners based on meditation experience, namely <1 year, 1–3 years, 4–6 years, 7–10 years and >10 years. The study investigated how experience affects learners in their perception of motivation, learning outcome and classroom climate, using one‐way ANOVA and post‐hoc analysis. Results showed a non‐linear ordered response—longer meditation experience does not in all cases increase benefits gained from meditation. A follow‐up group discussion with learners identified learning fatigue as a possible factor for the non‐linear results. In addition, through canonical correlation analysis, the study also showed that learning motivation and classroom climate is strongly correlated with learning outcome. The paper concludes with a discussion of results.

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.     

Effect of Marangoni Convection on Mass Transfer in Liquid Phase

Marangoni effectis of interestto the chemical en-gineers from both scientific and practical points ofview[1—6]. The Marangoni convection contributes tothe renewal of the interfacial surface and is capable ofincreasing the mass transfer rate, resulting in intensi-fication of separation processes such as distillation,extraction, absorption, and desorption. The theoretical studies of Marangoni instability inthe past were focused on determining the critical tran-sition point. The critical condit…

以CEFR为基础之华语文初级能力测验研发与应用

近年来,随着华语文学习需求的日益升高,使得以“母语为非华语者”的华语文能力测验也逐渐受到各国瞩目,然而,这些华语文能力测验仍有一些限制与不足之处。本研究目的是以欧洲语言共同参考架构（The Common European Framework of Reference,CEFR）为基础,参考蔡雅熏（2009）编制的《华语文能力指标》,研发A2级的华语文听力与阅读测验,并导人现代测验理论（item response theory,IRT）之技术,建立一套具有信度、效度的华语文能力计算机化测验。最后,本文透过次级量尺分数估计方法,探讨受试者在CEFR中四种语言能力之表现,研究显示受试者表达与理解能力优于互动与转述能力。
