浅谈英语教学中的情感教育

在我国,中小学英语教育是英语学习的启蒙教育,教师能否将学生顺利地引入英语学习的正轨,使学生能够主动地投入今后相对漫长的英语学习,除了教师有扎实的基本功和丰富的经验外,融情感于教学中这一教学策略更有其深远的重要性和必要性。教师能否合理地使用这种教学策略,对英语教学起着关键的推动作用。     

新课改下创设化学教学情景的探讨

新课程要求在教学过程中能够激起学生各种情感体验,要求学习者在知识的构建过程中能够产生学习动机和学习兴趣,在形成认知冲突后,能够具有解决问题的能力。新课程标准下化学教学的有效实施,在很大程度上依赖于化学情景的创设。     

体育教学中实施体验式学习的探索

体验式学习是一种以学生为中心的、有效的学习方式,是有效教学理论发展的新方向.采用文献资料法、逻辑分析法等研究方法,从体验式学习的内涵入手,对体验式学习在体育教学中的实施原则以及体验式学习在体育教学中应用的主要教学方法进行了分析,并提出体验式学习在体育教学中的操作策略以及局限性,旨在抛砖引玉,推动体育课程改革的发展.     

当代电影艺术的三重独立叙事结构

现代意义的电影是一门文学、图像、音乐相互交融的复合型艺术。由于其形式的直观性与生动性而易于为人所接受;又因为其内容仍持有一定文学性而不失趣味。电影艺术已成为当代艺术主流形式之一,而必须明晰的是,一部优秀的电影作品中文学、图像和音乐三要素彼此之间内容与形式的关系,它们是在彼此独立的基础上才能够做到真正意义上的相互交融。当下值得被探讨的正是各要素的本质核心,与要素本身、要素之间的构建方法。     

利益相关者视角下大数据技术驱动 高校学生评教改革研究

学生评教是我国高校教学管理和质量控制的普遍手段,但是正面临着诸多批评和挑战。根据利益相关者理论可以发现,学生、教师和管理者在学生评教过程中的利益诉求决定了其参加评教的行为选择,进而决定了学生评教制度的运行绩效。大数据技术能够高效批量处理多类型海量数据,精确分析学生评教数据,在学生评教过程中的应用场景非常广泛。基于大数据的评教系统不但允许学生、教师和管理者真实地表达和追求自己的利益诉求,而且可以通过约束利益相关者的机会主义行为来提高学生评教的效度。我国高校应该积极推进大数据技术在学生评教过程中的运用,推动大数据技术与本科教学质量控制的深度融合。     

我国运动员文化教育的典型情境探析

我国运动员的文化教育一直未取得实质性的突破。文章通过"书写时的惶惑"、"课堂上的鼾声"和"考场内的骚动"等运动员文化教育真实场景的描述,探讨了我国运动员在自身文化素质和学习过程等存在的诸多问题,提出了重构运动员文化教育体系的研究着力点,使竞技体育的发展最终回归到教育大环境中去。     

Introducing Secondary Education Students to Algorithms and Programming

In Greece, the development of the teaching of Information Technology (IT) in schools has been greatly influenced by the rapid development of technology, making IT literacy a priority for all individuals. Consequently, the teaching of algorithms and programming, with the ulterior motive of teaching modeling as well as problem solving, has been greatly limited in Secondary Education. However, we strongly believe that algorithms and programming constitute an important intellectual tool and should be included in basic education. In any case, both the research literature findings, as well as, our own experience confirm the fact that novice programmers come up against many mental obstacles in their attempts to understand the functioning of programs or the construction of algorithms. In order to deal with these difficulties and successfully teach the elementary concepts of algorithms and programming, we have developed didactic scenarios, which are based on specially designed educational software. In conjunction with this, we are attempting to develop a program for the systematic training of those students who will become IT teachers in Secondary or Primary Education. The most significant findings of our research are summarized as follows: (a) The development of educational software and its experimental use in the teaching process allow us to formulate several general rules related to the specific didactic characteristics, which these environments should include. (b) Educational software is effective only when it is incorporated within the framework of the didactic scenarios that the teacher organizes and which are supported by the software. (c) Teachers do not spontaneously use educational software in the context of this rationale. Therefore, specific training is required so that they adopt and use such software in didactic scenarios.

黄河源区径流变化模拟及未来趋势预估

黄河源区是黄河流域的重要组成部分,其径流变化影响着整个流域的水资源和生态系统安全。本文利用1976—2014年黄河源区径流、气象、数字高程模型DEM（Digital Elevation Model）、土地利用、土壤以及第六次国际耦合模式比较计划CMIP6（6^th Coupled Model Inter-comparison Project）中8个模式的3个未来情景（SSP126、SSP245和SSP585）气象数据,基于SWAT（Soil and Water Assessment Tool）水文模型,对黄河源区主要水文站的径流进行了模拟、未来预估和变化分析。研究表明：①SWAT模型对黄河源区历史径流模拟的适用性较好,径流模拟的不确定性较小,模拟值较接近于实测值。②参数敏感性分析表明27个与水文有关的参数都对径流模拟有一定的影响。其中,土壤蒸发补偿因子、湿润条件II下SCS（Soil Conservation Sevice）径流曲线数、浅层地下水径流系数的敏感性较强,径流受陆面蒸散发、下垫面和降水影响较大。③降水是影响未来径流的主要因素。在SSP126和SSP245两种未来情景下,吉迈、玛曲和唐乃亥3个水文站在2021—2100年的两个时期（2021—2060年和2061—2100年）年均流量均呈增加趋势;而在SSP585情景下,2021—2060年呈增加趋势,2061—2100年则呈减少趋势。相对于1976—2014年,未来近期（2021—2060年）唐乃亥和玛曲站年均流量在SSP585情景下增加幅度最低,SSP126情景下增加幅度最高;吉迈站在SSP245情景下增加幅度最高,SSP126情景下增加幅度最低;未来远期（2061—2100年）3个水文站除了吉迈站是在SSP126情景下增加幅度最低外,其余均是在SSP585情景下增加幅度最低,SSP245情景下增加幅度最高。研究结果可为黄河流域水资源管理、防洪蓄水和生态环境保护等提供科学依据与理论支撑。     

Teacher education futures: today’s trends,tomorrow’s expectations

Education is facing significant political and contextual challenges that will impact its future. This study employs a Delphi methodology to investigate teacher educators’ views of current trends and their consequences for teacher education futures. Interviews were conducted with a sample of expert teacher educators drawn from eight countries. This provided international perspectives on both local and global trends. The data were analysed to identify and elaborate key themes reported by the participants. The article draws on these themes to develop brief narratives around current developments that the teacher educators argue will have a major impact on the future of teacher education. These narratives are used to develop possible scenarios to inform thinking about teacher education futures.
