Integration of technical vocabulary into peer observation of teaching for Taiwanese elementary school English teachers’ professional learning

This study explored the integration of technical vocabulary into pre-observation conferences and its influence on English teachers’ professional learning and discussion in their post-observation conferences. The conceptual framework based on Harvey [2011. “A Sociocultural-Theory-Based Study of the Impact of Mediation During Post-observation Conferences on Language Teacher Learning.” Unpublished doctoral diss., University of South Florida] and Goe, Biggers, and Croft [2012. Linking Teacher Evaluation to Professional Development: Focusing on Improving Teaching and Learning. Denver, CO: National Comprehensive Center for Teacher Quality] was used to analyse the questionnaire, audio recordings, and documents collected in seven peer observations of teaching in Taiwan. This study has two major findings. First, English teachers regarded the technical vocabulary as stimuli for their professional learning; however, the range of technical vocabulary used during the post-observation conferences was limited. Second, three major factors affected their use of technical vocabulary. A new model was proposed in order to effectively integrate technical vocabulary into peer observations of teaching for elementary school English teachers’ professional learning.     

Pre-Service Teachers’ Innovation on English Activity Designs and Materials for Young Learners

Innovative designs on instructional strategies and activities for teaching English among younger learners were integrated into a language teacher education program in a university in northern Taiwan. This study analyzed 90 pre-service teachers’ final projects, questionnaires, and class materials to explore their innovations on English activity designs and materials. This study had three major findings. First, participants failed to identify the authentic materials taken from daily life. Second, participants integrated the materials into warm-up, presentation, or production of the lesson, rather than incorporating them throughout the whole instruction. Third, participants, their peers, and in-service teachers had different perceptions of innovation criteria. In order to effectively foster pre-service teachers’ innovation in designing instructional activities, three suggestions are provided.     

SDGs影响下的全球大学社会责任实践

为响应联合国可持续发展目标(SDGs),一股“大学社会责任”正在全球蔓延开。日本“地方知识基地推动计划”、欧盟大学社会责任计划(EU-USR)、“伊拉斯莫斯计划”、英国“教学卓越架构”等都在鼓励大学落实社会责任,这些计划和政策的实施对我国高校教学改革具有一定的借鉴和启发意义。

2005年全国高中学生化学竞赛初赛部分试题赏析

2005年全国化学竞赛终于尘埃落定,对于初赛试题,参赛学生普遍反映较难,得分也比往年低得多。今年是竞赛大纲修订后实施的第一年,试题对以后的命题和备考有导向作用。笔者感觉到相对于往年,有些题难度可能一下太大,对学生的要求较高。例如需要学生用文字说明热电效应现象,需用MO

农村薄弱学校运用现代教育技术的思考

农村薄弱学校的产生有着较为深刻的历史原因和社会原因,并成为实施九年制义务教育和全面推进素质教育的重要障碍。近几年来,政府和各地教育行政部门已认识到农村薄弱学校存在的严重弊端,将加强学校建设作为推进素质教育的一个突破口,并有针对性地采取了一些措施。我们认为,在加强农村薄弱学校建设的过程中,应充分认识和发挥现代教育技术优化教学效果、提高教育质量的重要作用,将现代教育技术作为农村薄弱学校改造过程中提高教师教学水平、优化学生学习效果、全面推进素质教育的重要手段。一、农村薄弱学校的差距据统计,就我国的中小学而言,…     

Effects of periodic carbohydrate ingestion on endurance and cognitive performances during a 40-km cycling time-trial under normobaric hypoxia in well-trained triathletes

The purpose of this study was to examine CHO ingestion on a cognitive task using a field-simulated time-trial (TT) under hypoxia in well-trained triathletes. Ten male triathletes (age: 22.1 ± 1.1 years; VO₂max: 59.4 ± 1.4 ml/kg/min) participated in this double-blind/crossover/counter-balanced design study. Participants completed 3 TT trials: 1) normoxic placebo (NPLA; FiO₂ = 20.9%), 2) hypoxic placebo (HPLA; FiO₂ = 16.3%), and 3) hypoxic CHO (HCHO; 6% CHO provided as 2 ml/kg/15 min; FiO₂ = 16.3%). During the TT, physiological responses (SpO₂, HR, RPE, and blood glucose/lactate), cognitive performance, and cerebral haemodynamics were measured. Hypoxia reduced TT performance by ~3.5–4% (p < 0.05), but CHO did not affect TT performance under hypoxia. For the cognitive task, CHO slightly preserved exercise-induced cognitive reaction speed but did not affect response accuracy during hypoxic exercise. However, CHO did not preserve the decreased Hb-Diff (cerebral blood flow, CBF) and increased HHb in the prefrontal lobe (p < 0.05) during hypoxic exercise, and CHO failed to preserve hypoxia-suppressed prefrontal CBF and tissue oxygen saturation. In conclusion, the present study demonstrates that CHO is effective in sustaining reaction speed for a cognitive task but not promoting TT performance during hypoxic exercise, which would be important for strategy-/decision-making when athletes compete at moderate high-altitude.
