2017 high school science inquiry laboratory equipment program

The significance of building a scientific inquiry laboratory

1. Building a scientific inquiry laboratory and carrying out scientific inquiry experiment teaching is an important guarantee for the renewal of science education concepts and the reform of new curriculum materials.

The new curriculum uses "scientific inquiry" as a breakthrough to change students' learning styles, emphasizing that scientific inquiry is an important learning activity. In order to make a fundamental change in the way students learn, and to ensure that students' autonomy and exploratory learning are implemented, the new curriculum reform first adjusts the curriculum structure so that students' activities time and space gain legal status in the curriculum. At the same time, the new curriculum standards guide students to discover problems and solve problems by changing the way in which learning content is presented, so that the learning process becomes a process of inquiry for students to ask questions and solve problems.

To carry out scientific inquiry activities, there must be a corresponding inquiry environment. Therefore, a scientific inquiry laboratory should be established to create a scientific inquiry experiment environment to meet the needs of students' inquiry learning, and to train students to participate actively, to be scientific, and to be diligent. Habits, thus cultivating students' scientific inquiry ability, the scientific attitude of seeking truth from facts and the spirit of exploration that dares to innovate.

2. Building a scientific inquiry laboratory and conducting scientific inquiry experiment teaching is an important part of implementing quality education.

Comprehensively promoting quality education, practical education and innovative education are important missions of all types of schools at all levels. The new concept of education quality emphasizes the cultivation of students' practical ability, innovation consciousness and innovative spirit, and emphasizes the coordinated development of knowledge, ability and quality. Building a scientific inquiry laboratory and conducting scientific inquiry experiments are important ways to achieve this goal. To transform knowledge into ability, it is necessary to conduct experiments through science, and knowledge must be transformed into quality. It is also necessary to conduct scientific inquiry experiments, and to cultivate innovative spirit is inseparable from scientific inquiry experiments.

3. Build a scientific inquiry laboratory, carry out scientific inquiry experiment teaching, and adapt to the new evaluation methods.

Focus: The exam was once, now, and perhaps will remain a school, the focus of a family.

Question: The current primary and secondary school evaluation and examination system is not compatible with the requirements for comprehensively promoting quality education. It is prominently reflected in the emphasis on screening and selection functions, ignoring the functions of improvement and motivation; focusing on academic performance, ignoring students' all-round development and individual differences; As a result, the process is neglected and the evaluation method is single; a sound teacher and school evaluation system have not yet been formed.

Hotspots: Experiments that use experiments as a carrier and examine scientific inquiry learning will become hot topics in the exam. In the national college entrance examination papers, the exploratory experimental exam questions have taken up a certain proportion. Shanghai and many provinces and cities across the country have begun to implement new test methods.

Countermeasures: To build a scientific inquiry laboratory and conduct research on exploratory experimental examination methods:

(1) Make a guess (hypothesis) and design an examination method for the inquiry plan (plan).

(2) Study on the examination methods for dealing with experimental facts.

(3) Research on evaluation methods for exploratory experimental programs.

(4) Comprehensive study of the examination methods of students' understanding of the inquiry process.

4. Actively equip the scientific inquiry laboratory to form the school's school-running characteristics

Courses and curriculum resources are at the heart of school education. The school's school-running characteristics depend to a large extent on the school's curriculum and curriculum resources, and the Science Research Lab is an important part of the curriculum resources of the new curriculum reform. Therefore, the establishment of a scientific inquiry laboratory, the formation of new characteristics of the school's curriculum resources, and then lay a good foundation for the formation of school characteristics.
