随着网络教育的发展,网络教育规模日益扩大,实现资源的可重用性以及系统的互操作性成为网络教育发展面临的主要问题。网络教育技术标准化是解决该问题的根本措施,但是规范或标准大多是用文字表述的,具有二义性,因此有必要对标准或规范的实现进行一致性测试。本文从学习设计规范出发,探讨了一致性测试的模型、方法及其过程,最后介绍了基于上述模型所开发的学习设计规范一致性测试系统。实验证明,该测试系统能够很好地完成学习设计规范一致性测试的要求,并且能够大大提高资源的可重用性及系统的互操作性。 相似文献

随着"人才培养模式改革和开放教育试点"的常规化推进以及现代科技发展的迅猛增长,原来学测考分离模式下学习测评的弊端愈来愈明显,表现出不适应远程教育课程改革的发展需求。Web2.0学习测评借助于原来的web1.0学习测评的基础上引用了现代学习测评理念,综合运用多种测评手段和方法,实现了课程考核多元评价目标,促进了现代远程教育教学课程改革的进程。本文旨在探索web2.0学习测评的发展必然、模型构成、实施效果,以及网考发展走向。 相似文献

如何根据学习者特点有效实现个性化学习一直是远程教育领域中面临的挑战。网格的发展使远程教育在技术、模式和理念等方面产生一场深刻的革命,提出了基于网格的个性化学习系统模型,给出其体系结构和实现技术方案。实例分析表明,该模型能较好地提取学习者的个性化特征,以组织特定的学习内容,采取特定的教学方式,加入特定的学习环境,并能动态反馈调整,是远程教育个性化的一个可行方案。 相似文献

怎样基于教育建模语言（Educational Modeling Language,简称EML）开展形式化层次的教学设计,是教学设计自动化领域中一个值得探讨的问题。IMSLD规范是一种经过改造的EML,具有目标、性质、基础、体系、提出者等五个方面的特点。基于IMSLD规范的学习（单元）设计有四条原理：指导思想原理、要素结构原理、设计层次原理、创设流程原理。从九个维度进一步对国际上已经推出的20多个IMSLD工具进行了归类和比较,并以《教育技术原理》教改课程为例,阐述了基于IMSLD规范的“学习单元”设计的具体过程,简介了“学习单元”设计制品的四条应用途径。 相似文献

This study validated the Chinese version of the Questionnaire on Teacher Interaction (QTI) in the Hong Kong context as well as examined the relationship between students’ perceptions of interpersonal teacher behaviour and their cognitive, affective and moral learning outcomes. Data were collected with the QTI and four other measures of student learning outcomes including a modified enjoyment scale of the Test of Science Related Attitudes, academic achievement, attitudes towards the teacher, and learning of values and attitudes. A total of 612 grade 9 students from 16 Mathematics, Chinese and English classes in six schools participated in the study. The Chinese version of the QTI was found to be a valid and reliable measure. Multiple regression analysis revealed that students’ perceptions of their teachers’ interpersonal behaviour were significantly related to their cognitive, affective, and moral learning outcomes. 相似文献

The purpose of this study was to investigate associations between students' perceptions of their biology teachers' interpersonal behavior and their laboratory learning environments and their attitudinal, achievement, and performance outcomes. A sample of 489 students from 28 senior biology classes in eight schools in Tasmania, Australia completed the Questionnaire on Teacher Interaction (QTI) and the Science Laboratory Environment Inventory (SLEI). Responses to two attitude questionnaires, achievement on an external written examination, and performance in laboratory practical tests were used as student outcome measures. Statistical analyses supported the reliability and validity of the QTI and the SLEI when used with senior secondary biology students. We investigated associations between students' perceptions of teacher behavior and their laboratory learning environment with student outcomes, including the unique and common contributions of the QTI and SLEI to variance in student outcomes. Associations with students' perceptions of the learning environment were stronger for the attitudinal outcomes than for the cognitive or practical skills outcomes. Some commonality between the QTI and SLEI scales was found in their contributions to the variance in attitudinal outcomes, but not in their contributions to variance in cognitive and practical skill outcomes. © 1999 John Wiley & Sons, Inc.

Research on teacher–student relationships and learning environments: Context,retrospect and prospect
《International Journal of Educational Research》2005,43(1-2):103-109
The program of research on teacher–student relationships described in this issue is an important part of the field of classroom learning environments, although it has its own distinctive and significant features. The questionnaire on teacher interaction (QTI), the main instrument used in this research, follows the strong tradition in learning environments research of using the perceptions of the participants in the classroom. Although this research program originated in the Netherlands, it now is truly international and the QTI has been translated into and validated in over a dozen languages. Not only has past research consistently replicated the advantages of positive teacher–student relationships in terms of promoting improved student outcomes, but positive teacher–student relationships also are worthwhile process goals of education. In the future, it would be desirable for the QTI to be used more frequently by teachers as a feedback instrument for guiding improvements in their classroom relationships with their students, and that qualitative data-collection methods are used more often in conjunction with the use of the QTI in research on teacher–student interaction. 相似文献

Within the domain of learning environments research many studies have investigated students’ perceptions of their teachers’ interpersonal behavior. The present study adds to this line of research by (a) focusing on primary education, rather than secondary education, (b) establishing associations between perceptions of teacher interpersonal behavior and perceptions of cultural elements of the learning environment rather than uniquely focusing on interpersonal behavior, (c) linking perceptions of teacher interpersonal behavior to affective student outcomes taking into account perceptions of cultural elements of the learning environment.Results of correlation analyses and multilevel analyses of variance, conducted on perception and outcome data of a sample of 2178 Australian years 5, 6 and 7 students in 103 primary classrooms are presented. Students’ perceptions of their learning environment were mapped with the Questionnaire on Teacher Interaction (QTI) and a primary version of the Cultural Learning Environment Questionnaire (CLEQ).Results indicate that, after correction for covariates, teacher proximity (QTI) and congruence (CLEQ) are significantly associated with students’ enjoyment in science. Also, strong associations were found between teacher proximity and all of the CLEQ scales. 相似文献

The research reported in this inquiry consisted of the application of two classroom learning environment questionnaires developed in a Western context to a culturally diverse context, namely, the Pacific Islands. The College and University Classroom Environment Inventory (CUCEI) and Questionnaire on Teacher Interaction (QTI) instruments were administered to intact classes of first- and second-year science students ( n= 257) at a regional university in the Pacific Islands, containing a total of 12 ethnicities. The data reveal that the QTI instrument holds good reliability for all scales, whereas the CUCEI holds reliability for only two scales. This may be due to the simple nature of the questions on the QTI whereas the questions on the CUCEI require more interpretation, the latter exacerbated by the fact that English is a second or third language for most participants. Surprisingly, there were few differences in perceptions of teacher student interaction based on ethnicity, but substantial differences based on gender. As reported in previous classroom environment research at the secondary school level, in this study, females perceived their environment more favourably than males. The data for the QTI reveal that the students perceive their classrooms to be highly teacher dominated, consistent with previous naturalistic studies of secondary schools and exploratory studies at the tertiary level in Fiji. Since almost all the graduates from this institution become science teachers, a cycle is completed. 相似文献
