Relationships among computational performance,pictorial representation,symbolic representation and number sense of sixth‐grade students in Taiwan

Twenty classes in ten schools with 627 sixth‐grade students in five cities in Taiwan participated in this study. The research provides information on the performance differences among written computation, pictorial representation, symbolic representation and number sense. The results of One‐way ANOVA analysis indicate that significant difference was found among WCT, PRT, SRT and NST tests, with F=536.327, p=0.000. The a posteriori comparisons show for each pair (WCT vs PRT, WCT vs SRT, WCT vs NST, PRT vs SRT and SRT vs NST) significant difference at the 0.001 level (p=0.000), except for the pair comparison between PRT and NST. This implies that these Taiwanese students were highly skilled in written computation but their written skills were not equally transferred to use of non‐computational paths that depended on symbolic representation, pictorial representation and number sense to solve similar problems.     

On the evaluation of systemic science education reform: Searching for instructional sensitivity

We propose a multilevel‐multifaceted approach to evaluating the impact of education reform on student achievement that would be sensitive to context and small treatment effects. The approach uses different assessments based on their proximity to the enacted curriculum. Immediate assessments are artifacts (students' products) from the enactment of the curriculum; close assessments parallel the content and activities of the unit/curriculum; proximal assessments tap knowledge and skills relevant to the curriculum, but topics can be different; and distal assessments reflect state/national standards in a particular knowledge domain. To provide evidence about the sensitivity of the multilevel approach in ascertaining outcomes of hands‐on science programs we administered close, proximal, and distal performance assessments to evaluate the impact of instruction based on two Full Option Science System units—Variables, and Mixtures and Solutions—in a Bay Area school district. Results indicated that close assessments were more sensitive to the changes in students' pre‐ to post‐test performance than proximal assessments. © 2002 Wiley Periodicals, Inc.

浅析高等职业教育人才培养的目标

我国高等职业教育是高等教育的重要组成部分，其能否发展成为高等教育中一支有别于普通高等教育的重要力量，关键在于人才培养模式上是否具有特色。高等职业教育以培养拥护党的基本路线，适应生产、建设、管理、服务第一线需要的德、智、体、美等全面发展的高等技术应用性专门人才为总体目标。其与普通中专的区别，是突出它的“高等性”；与普通专科的区别，突出它的“职业性”、“技术性”；与一般高等教育的区别，突出它的“应用性”、“复合性”。

基于统计学的艺术语言研究——以跨体式文学语言为例

艺术语言学是一门从艺术的角度研究语言的崭新的语言学分支学科。在当前语言学众多分支学科都呈现出活跃姿态的背景下,艺术语言学也需要通过不断更新学科观念和研究方法来推动自身的发展。本文试图通过对跨体式文学语言的分析,讨论艺术语言研究能否在延续思辨性研究的基础上,适当借鉴统计学实证性的研究方法;提倡艺术语言研究方法的多元化,对于进一步繁荣艺术语言学将是十分有利的。     

Performance equivalency between computer‐based and traditional pen‐and‐paper assessment: A case study in clinical anatomy

The time, material, and staff‐consuming nature of anatomy's traditional pen‐and‐paper assessment system, the increase in the number of students enrolling in medical schools and the ever‐escalating workload of academic staff have made the use of computer‐based assessment (CBA) an attractive proposition. To understand the impact of such shift in the assessment method, an experimental study evaluating its effect on students’ performance was designed. Additionally, students’ opinions toward CBA were gathered. Second‐year medical students attending a Clinical Anatomy course were randomized by clusters in two groups. The pen‐and‐paper group attended two sessions, each consisting of a traditional sectional anatomy steeplechase followed by a theoretical examination, while the computer group was involved in two similar sessions conducted in a computerized environment. At the end of each of the computer sessions, students in this group filled an anonymous questionnaire. In the first session, pen‐and‐paper group students scored significantly better than computer‐group students in both the steeplechase (mean ± standard deviation: 66.00 ± 14.15% vs. 43.50 ± 19.10%; P < 0.001) and the theoretical examination (52.50 ± 12.70% vs. 39.00 ± 21.10%; P < 0.001). In the second session, no statistically significant differences were found for both the steeplechase (59.50 ± 17.30% vs. 54.50 ± 17.00%; P = 0.085) and the theoretical examination (57.50 ± 13.70% vs. 54.00 ± 14.30%; P = 0.161). Besides, an intersession improvement in students’ perceptions toward CBA was registered. These results suggest that, after a familiarization period, CBA might be a performance equivalent and student accepted alternative to clinical anatomy pen‐and‐paper theoretical and practical examinations.

Integrating Various Apps on BYOD (Bring Your Own Device) into Seamless Inquiry-Based Learning to Enhance Primary Students’ Science Learning

Despite that BYOD (Bring Your Own Device) technology model has been increasingly adopted in education, few studies have been reported on how to integrate various apps on BYOD into inquiry-based pedagogical practices in primary schools. This article reports a case study, examining what apps on BYOD can help students enhance their science learning, and how students develop their science knowledge in a seamless inquiry-based learning environment supported by these apps. A variety of qualitative data were collected and analyzed. The findings show that the affordances of the apps on BYOD could help students improve their science knowledge without time and place constraints and gain a better sense of ownership in learning.
