【摘要】：目前,国内有关微课的研究已有较多文献报道,但大多侧重于翻转课堂、自主学习和教学策略等方面,而对于微课与手持技术结合的案例开发以及在实验教学中的应用研究鲜见报道。微课是记录教师围绕某个知识点(重点、难点、疑点)或教学环节而开展的教与学活动的课程单元或短期课程。目前主要以视频为主要载体。它具有主题突出、内容具体、教学时间短、成果简化、可多样传播、针对性强、反馈及时等特点。手持技术实验是由计算机和微电子技术相结合的新型数字化实验手段,具有便携、直观、实时、定量等特点。将融入手持技术实验的微课教学模式应用于传统教学,丰富了教学内容的表现形式,拓宽了表达途径。不仅很好地展现了教学内容,还给学习者以更直观的体验,有助于调动学生积极性,增强学生学习的自主性,从而提高课堂教学效率。同时,解决了部分实验条件达不到要求、无法完成实验的问题。因此,融入手持技术实验的微课教学模式在中学化学教学中将会有很好的应用前景。笔者在广泛查阅关于微课和手持技术研究文献后,综合运用建构主义理论、微型学习理论、泛在学习理论等理论知识,开发了融入手持技术的三个微课教学案例:《碳酸钠和碳酸氢钠性质比较》;《铝的化合物相互转化》;《食物中铁元素的检测》,并将开发的教学案例应用于教学实践中,在完成教学后,通过问卷调查研究以及对教师的访谈,综合平时教学实习中的观察,探析案例的实施效果。在论文的最后,笔者对于融入手持技术的微课教学案例应用于课堂教学的情况进行了反思。
[Abstract]:At present, there have been many literatures about microcourses in China, but most of them focus on flipping classroom, autonomous learning and teaching strategies, etc.However, there are few reports on the case development of the combination of micro class and handheld technology and its application in experimental teaching.Microlesson is a course unit or short course that records the teaching and learning activities carried out by a teacher around a certain knowledge point (key points, difficulties, doubts) or teaching links.At present, the main video as the main carrier.It has the characteristics of prominent theme, concrete content, short teaching time, simplified achievements, diverse dissemination, strong pertinence, timely feedback, and so on.Handheld technology experiment is a new kind of digital experimental means which combines computer and microelectronics technology. It has the characteristics of portable, intuitive, real-time and quantitative.The application of the teaching mode of microcourse into handheld technology experiment in traditional teaching enriches the form of teaching content and broadens the way of expression.It not only shows the teaching content well, but also gives learners a more intuitive experience, which is helpful to arouse students' enthusiasm, enhance students' autonomy in learning, and thus improve the efficiency of classroom teaching.At the same time, the problem that some experimental conditions can not meet the requirements and can not complete the experiment is solved.Therefore, the teaching mode of micro-course with handheld technology experiment will have a good application prospect in chemistry teaching in middle school.After consulting extensively the literature on micro-class and handheld technology, the author synthetically applies constructivism theory, micro-learning theory, ubiquitous learning theory and other theoretical knowledge.In this paper, three teaching cases of microcourse which are integrated into handheld technology are developed: comparison of properties of sodium carbonate and sodium bicarbonate; transformation of aluminum compounds; detection of iron in food; and application of the developed teaching cases in teaching practice.Through the questionnaire investigation and the interview to the teachers, this paper analyzes the effect of the case.At the end of the paper, the author reflects on the application of micro-class teaching cases in handheld technology in classroom teaching.
