正当前,国家语委正在宣传、贯彻国务院批准的《通用规范汉字表》。这时出现了"表外字不类推简化"的杂音。为了分清是非,下面简要回顾一下偏旁推简化的历史:1935年8月21日,南京国民政府教育部发布《第一批简体字表》,收324个简体字。在简化方法上,只有个体简化,没有偏旁类推简化。1956年1月13日,国务院公布《汉字简化方案》,收515个简化字和54 相似文献

大约百年前，出现了一种奇谈怪论：传统的学习语的方法太繁琐，要简化、简化、再简化，直简化到大众不费力就能掌握。中国人在这一百年中做了大量简化汉语与简化国语教学的工作，举其荦荦大端，包括取缔言、简化汉字、作媚俗、简化语教学等。以为这样学习中国语就是件轻而易举的事情了，然而，结果却事与愿违。 相似文献

This is a report of a developmental research study that aimed to construct and validate an instructional design (ID) model
that incorporates the theory and practice of multiple intelligences (MI). The study consisted of three phases. In phase one,
the theoretical foundations of multiple Intelligences and ID were examined to guide the development of such model. In phase
two the model components were determined and an initial model was constructed. In phase three, the model was reviewed and
validated by experts in the field of ID through a three-round Delphi study. The result was a revised and validated Multiple
Intelligences Design Model. This paper presents the decision-making processes and procedures used in model development, and
provides a framework for the internal validation of ID models using expert review procedures. 相似文献

基于"关联—顺应"模式和"语码转换顺应性模式",通过问卷、访谈和录音转写的方式,文章提出教师课堂语码转换的"关联—顺应模式",对课堂语码转换现象进行了阐释。通过分析发现英语教师课堂英汉语码转换的使用是教师寻求关联语境,并对所关联语境进行动态顺应的过程;是为实现特定的教学和交际目的,在不同意识水平的基础上做出商讨型的语言选择。在外语课堂这一特殊语境中,语码转换常被视为一种有效的教学语用策略和与学生沟通的有效交际策略。 相似文献

ABSTRACTModel-based instruction offers numerous benefits to students, including increased content knowledge and critical thinking. This study explored the differences in the knowledge outcomes and reasoning processes employed by undergraduate students in an introductory biology lab as they constructed, revised, and simulated a computational model of a prokaryotic gene regulatory system. We analysed post-lesson conceptual models (n?=?335) and audio-recorded small group discussions (n?=?10) of students that either constructed and revised a computational model and then investigated a pre-constructed computational model or only investigated a pre-constructed computational model to determine the impact of constructing and revising a computational model. No significant differences were found between the mental models of students who constructed and revised a computational model and those who only simulated a pre-constructed computational model. However, this study demonstrated that constructing and revising a model before simulating it offered additional benefits to students by fostering deeper cognitive reasoning processes. Constructing and revising a model elicited more explanatory and evaluative reasoning and prompted students to discuss the underlying mechanisms of the biological system. 相似文献

自主学习合作探究的教学模式是以建构主义理论为依托的,以发挥学生在教学中的主体作用,培养学生学会学习为目标的教学模式,新课程改革和高中历史教材的特点有利于推行这种模式.在开展自主学习合作探究教学模式中,教师要更新教学观念,采取灵活多样的教学方法,构建平等和谐的新型师生关系,并和多媒体教学结合起来,才能使该模式有效开展.并不是所有的历史课都适合该模式,教师要结合实际选用. 相似文献

What model does one use to understand interpersonal communication and how does one apply such a model when teaching a course in interpersonal communication? The author presents and applies a self‐validation model and topology of transactional relationships to help select concepts, principles, and skills that are essential for the study of interpersonal communication. 相似文献

This study proposed using the elaborated learning and knowledge building model (LKB model) derived from Nonaka and Takeuchi’s knowledge management model for supporting cross-organisational teacher development in the temporarily extended organisations composed of universities and schools. It investigated the main LKB model components in the context of teachers’ professional development; the kind of technological barriers to be overcome in order to implement such a model; and what the application scenarios of an LKB model are. Four groups of stakeholders, altogether 10 persons, were interviewed for the study. Data were analysed using a qualitative framework analysis method. The main findings of the study exposed the following difficulties in applying an LKB model for extended organisations for teacher development: teachers’ sense of identity, technical issues and organisational barriers. Several scenarios were proposed for the use of technology to facilitate the LKB model in the teacher development context using the e-portfolio and social learning resources repository. 相似文献

The major focus of this study is to propose a new research model, namely the Modified CGI gender model, for the study of gender
differences in mathematics. This model is developed based on Fennema, Carpenter, and Peterson’s (1989) CGI model. To examine
the validity of this new model, this study also examines the gender differences in teacher and student beliefs about mathematics
and compares gender differences between teacher and student beliefs about the importance and difficulty of certain mathematics
topics. Using the British Columbia Mathematics Assessment data, the study conducted a series of ANOVA. The findings of this
study indicate that the new model appears to be a useful tool to describe gender differences in mathematics and to guide research
in this area. The conclusions drawn from the data analysis show that male and female teachers differed significantly in their
beliefs about Numbers and Operations. Male teachers perceived this topic to be more important than female teachers. Second,
gender differences have been largely found in student beliefs about the difficulty of the selected topics. Finally, gender
differences found in teacher beliefs are similar to the gender differences in student beliefs about the importance and difficulty
of mathematics topics. 相似文献

One barrier that human resource managers may face in evaluating their training programs is lack of expertise in how to customize and implement an evaluation model. Using a case study approach, we conducted a research study to document the process and results of customizing and implementing a training program evaluation model in an organization. In this article, we describe the steps that the HRD managers in one organization used to customize and implement the Training Effectiveness Evaluation (TEE) model (Swanson & Sleezer, 1987), and the decisions and actions that were required to move from the model to actual practice. We also describe how the decisions and actions in implementing the model influenced the evaluation results. When the project began, the HRD managers lacked expertise in customizing and implementing an evaluation model. By the end of the project, they had overcome this barrier and gained new skills. They had learned to use the tools of the TEE model and had customized the model to meet the needs of their organization. 相似文献
