作业,一个时时被人提起而又时时被人忘记的教学环节,担负着巩固学生所学知识、培养学生学习能力、检测学生学习过程和成果并促使教师改进教学的重要任务。随着新课程的深入实施,教师的教学观念、教学形式和教学水平都在发生质的变化。然而,“题海战术”、“拿来主义”仍是不少教师常用的手段,“形式单一”、“脱离生活”、“缺乏应用”等问题仍不同程度地存在于数学作业设计之中。这不得不让我们再次提起“数学作业设计”这个话题。如何以新课程标准中“以学生发展为本”的教育教学理念为依据,设计新型的数学作业,利用数学作业使学生得到充分的发展,进而不断提升自己的教学水平?作为教师,应该始终保持对数学作业设计研究的热情和热度,根据教学内容和教学实际,不断设计出符合学生认知特点的形式多样、内容丰富、具有探索与思考价值的数学作业,真正使学生的数学学习能力和数学素养得到发展和提高。本期组织的这6篇文章,既有对数学作业设计理念和关系的分析,也有名特优教师对数学作业设计的沙龙研讨,更有一线学校的老师对不同数学作业形式设计的教学尝试,我们希望这组稿件对广大的一线老师设计数学作业有所启发、有所帮助。
Homework, a teaching process that has been brought up from time to time and forgotten from time to time, carries the important task of consolidating students’ knowledge, fostering students’ learning ability, testing students’ learning process and achievement and prompting teachers to improve their teaching. With the further implementation of the new curriculum, teachers’ teaching concepts, teaching forms and teaching levels are undergoing qualitative changes. However, questions such as “questioning the sea tactics ”, “fetishism ” are still commonly used by many teachers, “form a single ”, “out of life ”, “lack of application ” and other issues are still different To a degree exists in the design of mathematics. This forced us to bring up the topic of “math homework design” again. How to design a new type of mathematics homework based on the education and teaching philosophy of “developing student-centeredly” in the new curriculum standard, and make full use of mathematics to make students develop fully so as to improve their teaching level? As a teacher, Always maintain the enthusiasm and enthusiasm for the design and study of math homework, according to the teaching content and teaching practice, continue to design in line with the cognitive characteristics of students in various forms, rich in content, with the value of exploration and thinking of mathematics homework, the real math learning ability of students And mathematical literacy has been developed and improved. The six articles organized by this issue not only analyze the design concept and relationship of math homework, but also discuss the salon design of math homework by famous gifted teachers, as well as teaching attempts by different frontline teachers to design different math homework forms. We hope this set of manuscripts will inspire a large number of front-line teachers in designing math homework and will be helpful.
