Mathematics interest aims to make students use what they have learned comprehensively to solve problems in real life situations, let them feel the charm of mathematical thinking methods and the connection between mathematics and life in activities, and further stimulate students' interest and discovery in exploring mathematical problems.
While appreciating the beauty consciousness of mathematics, we can further improve students' thinking ability, stimulate the consciousness of solving problems and improve the strategy of solving problems, thus promoting the improvement of mathematics literacy. At present, from the teaching practice of this unit of senior frontline teachers, the fun of mathematics has not been implemented, and students have not felt the fun of mathematics, especially dripping experiment, dense shop, autumn outing scheme design, symbolic long-distance running, rebound height, drawing campus plan, etc., which have been ignored in teaching.
Textbooks are the basis of teachers' teaching, so it is imperative to make a comprehensive, detailed and in-depth analysis of their writing intentions. By exploring the mathematical ideas and comprehensive practical contents of mathematics permeated in each section, we can correctly establish and grasp the teaching objectives, thus making mathematics teaching more directional and targeted.
For example, in the fifth grade math fun column of Beijing Normal University, the teaching content is to design an autumn outing plan, with the goal of helping students accumulate activity experience and improve their practical ability. This class is a comprehensive practical activity class. After designing the autumn outing situation, the task mode of the activity is presented through students' dialogue, discussion and questions. In the textbook, four parts are designed to guide students to complete the task. These four parts are design scheme, hands-on practice, exchange and reflection, and self-evaluation.
Instructional design refers to the teacher's arrangement of teaching, which is an important part of teacher's teaching, including how to grasp the curriculum objectives, learning period objectives, unit objectives, class objectives, link objectives and many other contents. How to preset the teaching process and create problem situations? How to design teaching activities and choose appropriate teaching methods? How to creatively design exercises, how to deal with the problems of presupposition and classroom dynamic generation. Through the design of these contents, the interesting goal of mathematics is realized.
For example, in actual teaching, teachers take the typical teaching design of integration and practice as the research breakthrough point, and focus on different teaching designs of the same content. Through the in-depth study of the teaching design of typical lessons, they explore the basic teaching concepts and models of integration and practice in mathematics interest.
In practical teaching, teachers can also decompose teaching objectives into three-dimensional objectives: knowledge and skills, process and method, emotional attitude and values, so as to cultivate students' comprehensive ability to apply mathematical knowledge and highlight the interesting teaching characteristics of mathematics. For example, when designing an autumn outing plan, teachers design knowledge and skills to help students accumulate experience in mathematics activities and feel the connection between mathematics and daily life through this activity.
What information do you need to know before going to the scenic spot to save time, money and energy to the maximum extent? In the data collection, design, communication and division of labor of activities, the design scheme and process of activities are reasonably evaluated, so as to develop students' reflective ability. In order to improve the teaching effect of this section, teachers can design some scenic spots according to local conditions to let students feel the connection between mathematics and life.
