Item Mobile-device-supported problem-based computational estimation instruction for elementary school students(International Forum of Educational Technology & Society, 2010-07-01) Lan, Y. J.; Sung, Y. T.; Tan, N. C.; Lin, C. P.; Chang, K. E.This study implemented a three-stage problem-based estimation instruction scenario and combined it with mobile technology to provide elementary teachers with an effective e-tool for observing student estimation and leading effective class or group discussions on the selection and assessment of appropriate strategies for solving daily estimation problems. Twenty-eight fourth graders were randomly sampled and assigned to two groups: the experimental group (problem-based estimation instruction using mobile devices) and the control group (problem-based estimation instruction without mobile devices). The analytical results demonstrated that problem-based estimation instruction could effectively help students learn computational estimation skills. Moreover, using mobile devices for problem-based computational estimation instruction appeared to help students discuss and cooperate with others, and moreover the mobile-device-supported problem-based estimation scenario helped students develop metacognition knowledge of estimation strategies.Item Let us read together: Development and evaluation of a computer-assisted reciprocal early English reading system(ELSEVIER, 2009-12-01) Lan, Y. J.; Sung, Y. T.; Chang, K. E.This study attempts to implement a cooperative reading environment for EFL early reading using a mobile-device-supported computer-assisted reciprocal early English reading (CAREER) system, and to evaluate its effect on the early reading skills and learning behaviors of elementary EFL learners. The design rationale of CAREER is based on the three essential components of effective reading instructions: balanced reading structure, immediate and specific feedback, and reciprocal learning scenario. Analytical results indicate that the CAREER system reduces the problems experienced by students in a conventional cooperative learning environment and effectively helps elementary EFL learners orchestrate their learning while completing individual reading tasks and pursuing group goals. The results also demonstrate that CAREER appears to be able to benefit elementary EFL learners in developing reading skills. In sum, with the support of CAREER, the early reading skills of elementary students are benefited by cooperating with each other.Item Collaborative early EFL reading among distributed learners: A simulation pilot study(The Journal of the JALT CALL SIG, 2006-08-01) Lan, Y. J.; Sung, Y. T.; Chang, K. E.It is widely accepted that reading provides important opportunities for second language (L2) development, however, in Taiwan sources of L2 input are often limited for learners in English as a Foreign Language (EFL) settings. This problem is compounded by environmental constraints such as students’ diversity in reading abilities, the socio-economic gap between urban and rural students, class sizes, time constraints and available resources, and dealing with these constraints effectively requires new pedagogies and tools. We designed a wireless peer-assisted leaning system for early EFL reading to enhance online collaborative EFL reading and provide EFL learners with an opportunity to teach and learn with each other. In this study we examine the use of this wireless reading system in a conventional EFL class to simulate a distributed learning situation. The results suggested that wireless EFL reading may emerge as a flexible and portable solution to the pedagogical challenges that exist in conventional EFL reading and teaching environments.
