指向初中数学核心素养的变式学习设计策略探究

1.创新例题设计通过初中数学变式教学模式的实施,激发学生的学习兴趣,提高学生的学习效果。变式学习的设计中,可以通过例题设计的创新进行展开,教师需要充分考虑学生的兴趣爱好、实际应用、思维训练等因素。过提供多样化、富有挑战性的实践案例,引导学生主动思考、探索和解决问题,提高学习动机和理解能力。同时,教师可以根据学生的反馈和表现,及时调整和改进例题的设计,从而更好地适应学生的学习需要。在初中数学中实施变式教学模式时,可以通过实例的创新设计,激发学生的思维能力和学习兴趣。
2.数学公式设计在初中数学中实施变式学习设计时,教师也可以从数学公式的教学设计入手,教师可以根据数学公式之中的多个要素进行设计。帮助学生理解和掌  握数学概念。例如,在进行直角三角形的教学时,教师尽可以根据其中的条件设计多个变式问题,要求学生利用勾股定理求解。教师可以给出两条直角边或斜边的长度来要求学生计算另一条边的长度或角度。让学生能够更加深入地理解和应用数学概念,培养他们的问题解决能力和创新思维。同时,也能够提高学生的数学兴趣,并加深他们对数学知识的理解和记忆。
3.重视学生个人的主体地位新课标要求教师以学生个人为主体进行对学生综合素质的培养。在初中数学课堂教学过程当中,教师应该积极的引导学生进行对数学知识的求知和探索。教师单方面输出并不能有效的提高数学思维能力。教师引导学生进行对数学的积极思考和探索。这样可以让学生在学习过程当中获得满足感。也能够让学生增强对于数学的求知和探索欲望,促进学生的全面发展。
4.强调方法指导在双减政策之下,教师应该充分的意识到,数学教学课堂不再仅仅是对学生进行数学知识的传授以及灌输。而是要更加重视学生综合素质的培养,因此学生在开展变式学习设计时应该更加注重对于学生综合能力的培养。教师更应该促进学生提高自主学习和规划的能力强调学生的主体地位,让学生通过课前预习、课上学习以及课后复习来对数学知识进行学习和巩固,让学生能够更加独立且有目的性和计划性的进行数学知识的学习。从而促进学生数学逻辑思维能力的提高以及个人综合素质的培养。
5.开展情景教学新课标提出明提出:“基于必修、选择性必修和选修课程的某些内容,学生能够对较复杂的数学问题,通过构建过渡性命题,探索论证的途径,解决问题。”核心素养顺应时代变迀和社会发展应运而生,数学核心素养是我国教育方针的细化和具体化。
新课标明确提出六大数学核心素养:数学抽象、逻辑推理、数学建模、数学运算、直观想象和数据分析。在新课程标准之下,教学活动重视学生的自主学习,由学生主动探索学习而得以建构自己的知识,并达成预设的学习目标。换言之,在新的课程标准下,“学”比“教”更受重视,由于知识建构的主体在学生个人,如何学习就成为教学思考的重要课题。依据新课程理念,深入开展情境教学研究,最大限度地调动学生学习的主动性,激发课堂活力,提高教学效率;让课堂教学“提速”,让生活走进课堂,把学习与体验生活结合起来。

同时,由于数学的内容比较庞杂,因此学生在学习数学知识的过程当中难免会遇到问题,这可能会严重影响学生的学习兴趣,使学生降低对于数学知识理论学习的探索欲望。尤其是初中的数学知识难度过高,这不只是单纯的“刷题”就可以掌握的。教师需要在学生学习数学知识的过程当中进行积极的引导,尽量培养学生的数学逻辑思维。教师也可以根据学生熟悉的生活实际进行教学情境的创设。
通过设置适当的教学环节让学生能够更加身临其境的对理论知识进行学习和吸收。让学生面对内容丰富的数学理论知识过程当中不至于手足无措。教师在学生迷茫的阶段充分发挥自己的导向作用,构建更加灵活多变的数学问题场景,以引导者的身份帮助学生训练自己的逻辑思维。让学生在更加轻松的学习氛围当中进行自主学习,掌握数学的学习方式,提高学习效率。

研究指向初中数学核心素养的变式学习设计探究的意义

教师在开展变式教学的同时,通过适度的引导让学生合理的把握学习的重点,锻炼学生的思维能力,培养学生进行自主学习。教师在课上进行释放的过程当中需要对进行自身进行规范,及时的找出自身的存在的问题,避免因为教师个人问题对学生学习的影响。在教师引导学生学习的过程当中教师也需要注意引导方式不能过于直接,引导程度也不能过大。
在学生出现学习困难的问题时,教师应该从侧面对学生进行引导主要是引导学生自己思考解决问题,找出问题所在,而不是直接点出结论。让学生在学习的过程当中少走弯路,节约时间。但是同时也锻炼了学生自己探索的能力,培养了思维模式的发展。
教师在教学过程当中要明确学生的主体地位,但同时教师也不能对学生的学习完全放任,教师应该充分发挥自己的主导性,在课堂的进程当中教师应该把握好对于教学环节的开展以及时间的合理分配。让学生在有限的课堂时间内,通过教师提前的准备,得到更多的收获。在整合数学知识的过程当中,教师也应该适当的引起学生对于知识的求知和探索能力,让学生自主的探索并且深刻掌握数学规律,进一步促进学生核心素养的提高。

结束语

综上所述,可以见得在核心素养视阈之下,对于初中数学教学进行改革和优化是迫在眉睫的。避免由于数学知识的枯燥乏味不造成的学生对于数学的学习兴趣以及探索和求知的欲望的降低。开展变式学习设计,使教师向学生充分地传达数学知识,大大的提高了初中数学课堂的学习效率。
初中数学教师积极的探索培养学生数学抽象、逻辑推理、数学建模、数学运算、直观想象和数据分析等六大基本素养的方式和方法, 培养学生数学基本思维能力以及学习情感、态度和价值观的锻炼。促进学生的综合能力的提升和学生个人的全面发展,培养综合性人才。
