单元积件式组合教具是以单元科学概念(实验)体系为内容,借鉴信息技术学科的积件思想,改变传统单一、零星的教具研制模式,是教师在充分解读单元教材与实验探究中突出的疑难问题后,由一个个经过科学建构、设计与加工后的单一结构性积件组合而成的多功能组合式教具。随着新课改的不断深人,现有教学仪器不能完全满足学生实验操作的需求;同时,零星、单一的自制教具也不能更好地辅助学生建构完整的单元概念。为此,课题组以“沉和浮”单元为例,师生合作开展了单元积件式组合教具的研制与应用研究,从中优化学生的实验过程,变革教具的研制思维,创新实验的教学方式,对提高科学单元实验的整体探究效率,发挥着非常有效的作用。 Unit modular integrated teaching aids is a unit concept of science (experimental) system as the content, learn from the information technology discipline plot idea, change the traditional single, sporadic teaching aids development model is the teacher in the full interpretation of the unit textbook and experimental exploration of outstanding After the difficult problem, from a by science through the construction, design and processing of a single structural pieces of a combination of modular multi-functional teaching aids. With the continuous deepening of the new curriculum reform, the existing teaching instruments can not fully meet the needs of students’ experimental operation. Meanwhile, sporadic and single self-made teaching aids can not better help students to construct a complete unit concept. To this end, the research team to “Shen and float ” unit, for example, the teacher and students to carry out a unit-piece modular teaching aids development and application of research, optimization of students from the experimental process, change teaching aids the development of thinking, innovative experiments Teaching methods play an extremely effective role in improving the overall efficiency of scientific experiments.
