利用多种学习情境促进学生有效学习数学

正让学生在具体的情境中学习数学,是新课标倡导的一种教学理念,也是促进学生自主有效学习的一种重要教学方式,它就好比学生学习的"催化剂"。在小学数学教学中,有效数学课堂教学是每个数学教师追求的教学最终目标。那么如何利用学习情境引导学生自主有效地学习数学?下面笔者结合多年的教学实践,谈几点具体做法,以便抛砖引玉。一、利用生活情境,促进学生有效学习     

以情境促低年级学生有效学习数学

低年级学生的特点是好奇、好动,注意力不能持续较长时间,极容易被一些新鲜事物所刺激和吸引,针对这一特点来开展有效教学,情境教学无疑是一种相当不错的策略。以下是我在课堂教学中使用情境教学的一些有效策略。     

创设有效数学情境,提高学生学习兴趣

随着新课程标准的不断修订,小学数学教育也在一定基础上得到了改善.本文主要依据作者现有的教学经验进行分析,针对课堂教学中与学生的有效互动,来提高学生的学习兴趣.     

创设有效学习情境 激发学生探究欲望

苏霍姆林斯基说过：在人的心灵深处都有一种根深蒂固的需要，这就是希望自己是个发现者、研究者、探索者。而在儿童的精神世界中，这种需要特别强烈。因此，教师在教学中，要创设诱人深入的探究性学习情境，激发学生产生探究欲望，让学生能够积极主动地投入到学习活动中去。     

小学数学课堂有效学习情境的创设与实践

实施新课程以来,小学数学课堂发生了巨大的变化,在实施有效教学的实践中,情境教学无疑是提高教学效率的一种好方法.本文聚焦数学课堂,从创设问题情境、实验情境、趣味情境、激励情境等四个方面入手,全面阐述了如何充分挖掘情境教学的潜能,因材施教,因时施法,逐步将教材的思想性、知识性、趣味性融为一体,增强学生探究数学知识的自信心,提高学习的兴趣,优化教学过程,最终全面提升学生多方面的素养.     

构建有效的数学情境

如何创设适合学生发展的有效数学问题情境,使数学学习真正成为既具生成发展意义,又不失扎实有效作用的过程,笔者结合一些具体教学实践,谈几点想法和做法。1.思考性是构建有效情境的首要因素创设情境固然需要尽可能联系现实生活,但真正好的数学情境的根本标志不在于一定要联系现实生活,而在于必定能有效激发学生的数学思考,引导学生将思维聚集于     

例谈小学数学情境的有效创设

情境教学法已经被广泛应用于教育教学中,并且也得到了师生的认可。小学生的注意力不易集中,如果教师一味地采用“讲授”等传统的教学方式,学生会感到枯燥,难以集中注意力于教师的教学中。而情境的创设能够有效集中学生的注意力,促进课堂教学的有效开展。由此,教学情境的创设就显得尤为重要。     

构建有效的数学学习情境

《数学课程标准》明确提出,要让学生在生动具体的情境中学习数学,在现实情境中体验和理解数学,应充分利用学生的生活经验,创设与学生生活环境、知识背景密切相关的,又是学生感兴趣的学习情境。     

创设有效数学教学情境的策略

＂让学生在生动具体的情境中学习数学＂是小学数学新课程教学的重要理念。对数学教师而言,如何创设有效情境、促进主体学习,让情境真正成为教学内容和学生求知心理的一座桥梁,是当前一个亟须探索的研究课题。笔者认为,新课改下的有效情境创设应注意以下几个方面。     

让学生在反思情境中学习数学

反思情境是教学情境中最重要的一种,它因实际需要渗透于任何有效课堂之中。作为教师,只有深刻领悟反思情境创设的时机、方法与价值,才能让其更好地服务于学生的数学学习。也才能更稳健地推动学生的发展。     

浅析职高生数学学习现状与对策

在职业高中生的学习中,数学是非常重要的一个学科,需要增强他们的学习主动性、自信心等,才能进一步提高职业高中生的数学学习效率,最终促进职业高中生综合素质全面发展。本文就职业高中生数学学习心理进行分析,提出职业高中生数学学习的主要对策,以培养职业高中生良好的学习习惯。     

The role of reflection in mathematics learning

Reflective abstraction is central to the theory of constructivism as put forth by von Glasersfeld. In coming to know, persons make major cognitive advances by taking their actions as objects of thought. Leamers move beyond being in the action when they engage in reflection. There are serious limitations in the explain-practice method of instruction and active learning. Performing even self-generated mathematical operations does not have the power which results from reflecting on the activity. Problem-centered learning, an instructional strategy which has been shown to provide rich opportunities for reflection, is examined. The nature of reflection in mathematical activity is also considered.     

The pedagogical agent enhances mathematics learning in ADHD students

Gaining the attention is the first key step to enhance learning. In Attention-Deficit/Hyperactivity Disorder (ADHD) as the most prevalent deficit in school age, the learners face some impairment in attention that requires appropriate intervention. An environment that embedded Pedagogical Agent in computer-assisted instruction (CAI) has been designed to support learning through gaining and guiding attention to relevant information for these students. This study investigated how much the presence of pedagogical agent can improve learning in ADHD students. The learning environment was integrated with a pedagogical agent, named Koosha, as a tutor and motivator. This study employed a pretest and posttest experimental design with a control group. The statistical population was 30 boy students with ADHD in primary school from the North of Iran. The participants were randomly assigned to work with either an agent presenting a multimedia program or without an agent in mathematics. The results (Analysis of covariance -ANCOVA) suggested that experimental and control groups show a significant difference in mathematics achievement. According to this research, using the pedagogical agent can enhance the learning of ADHD students; so it can be considered as a valid school-base intervention for these students.     

The role of visual representations in the learning of mathematics

Visualization, as both the product and the process of creation, interpretation and reflection upon pictures and images, is gaining increased visibility in mathematics and mathematics education. This paper is an attempt to define visualization and to analyze, exemplify and reflect upon the many different and rich roles it can and should play in the learning and the doing of mathematics. At the same time, the limitations and possible sources of difficulties visualization may pose for students and teachers are considered. This revised version was published online in August 2006 with corrections to the Cover Date.     

The role of mathematics learning centres in engineering education

Mathematics departments in many universities, in many countries, are under pressure. The demand for mathematics undergraduate programmes is diminish- ing and service mathematics is under threat. In particular, engineering schools are either reducing the number of mathematics courses in degree programmes or engineering staff are teaching mathematics as part of engineering analysis courses. There is also a strong trend in engineering education to make greater use of computer courseware like Mathcad, Matlab and other software systems for the mathematical and statistical components of engineering programmes. Engineer- ing education is undergoing substantial change. The mathematics of engineering programmes will need to change accordingly. Mathematics learning centres have been established in many universities world-wide. Initially their main role was to provide assistance for those who had insufficient levels of competency in pre- requisite mathematics. However, these centres can also make a very useful contribution to the latest trends in the mathematics education of engineering undergraduates. This paper will describe that contribution.

Proof schemes and learning strategies of above-average mathematics students

What patterns can be observed among the mathematical arguments above-average students find convincing and the strategies these students use to learn new mathematical concepts? To investigate this question, we gave task-based interviews to eleven female students who had performed well in their college-level mathematics courses, but who differed in the number of proof-oriented courses each had taken. One interview was designed to elicit expressions of what students find convincing. These expressions were categorized according to the proof schemes defined by Harel and Sowder (1998). A second interview was designed to elicit expressions of what strategies students use to learn a mathematical concept from its definition, and these expressions were classified according to the learning strategies described by Dahlberg and Housman (1997). A qualitative analysis of the data uncovered the existence of a variety of phenomena, including the following: All of the students successfully generated examples when asked to do so, but they differed in whether they generated examples without prompting and whether they successfully generated examples when it was necessary to disprove conjectures. All but one of the students exhibited two or more proof schemes, with one student exhibiting four different proof schemes. The students who were most convinced by external factors were unsuccessful in generating examples, using examples, and reformulating concepts. The only student who found an examples-based argument convincing generated examples far more than the other students. The students who wrote and were convinced by deductive arguments were successful in reformulating concepts and using examples, and they were the same set of students who did not generate examples spontaneously but did successfully generate examples when asked to do so or when it was necessary to disprove a conjecture.
