This paper makes a preliminary discussion on the present situation, effectiveness, assignment form and evaluation method of scientific inquiry homework in primary schools, aiming at exploring new ways and methods that conform to the characteristics of the subject and the students' learning reality and can effectively improve students' innovative spirit and practical ability. The research on scientific inquiry homework design in primary schools plays a very positive role in guiding students to ask questions objectively, use various methods independently, scientifically analyze and solve problems, and helps to improve the breadth and depth of students' thinking.
Keywords: primary school scientific inquiry homework evaluation methods
First, the research background
Since the implementation of quality education, in order to reduce students' schoolwork burden, it is required that there is no written homework in primary school science, and some exploratory homework can be arranged after class to cultivate students' innovative consciousness and practical ability, so as to apply what they have learned. With the implementation of this reform, the majority of science teachers are at a loss, and there are a series of problems in the assignment of science classes, which are mainly reflected in the following aspects: 1 The content of science homework is limited to classroom knowledge and textbooks, mostly to complete after-school exercises, or to complete synchronous exercises, or to preview new lessons. 2. There are many mechanical and repetitive tasks, and the pursuit of a unified answer. 3. The homework in science class is monotonous and rote learning. 4. Students' hands-on practical work is less and the operation is difficult.
So how to arouse the enthusiasm of students to do homework and make them take science homework as something they need and are willing to do? At the same time, it can reduce students' schoolwork burden and improve their comprehensive ability. These problems are worth studying.
Second, the form of inquiry-based homework design
The forms of inquiry homework design should be rich and varied, and the common scientific homework forms I use are as follows.
1. Practical activity homework. For example, the small production of science class can be combined with a research topic in the textbook. For example, let students use the materials provided by teachers and the materials they need to make a ship that can carry goods; Encourage students to design cars in groups and make an elephant out of the materials around them? As fast as a rocket? Cars; Encourage students to make one with the least materials? Egg protector? Wait a minute.
2. Data collection. For example, after learning magnetic levitation, students can find information about magnetic levitation through the internet, newspapers and other materials. In addition, students can get some latest scientific news through TV, radio and magazines, or learn about a scientist or his deeds. Finally, they should organize these materials into small excerpts, take notes or write down their thoughts after reading.
3. Small scientific papers. The process of learning science is generally carried out in the form of inquiry. Students go through the process of finding problems, asking questions, making assumptions, experimental verification, discussion and analysis, and drawing conclusions in scientific inquiry.
In this process, students keep exploring, making progress and realizing? Another village? Field. This kind of experience is very valuable to students. The form of writing small papers shows the process of students' inquiry thinking well.
4. Investigation report. The scientific teaching process is generally centered on inquiry. In the process of scientific inquiry, students have experienced the process of discovering problems, asking questions, making assumptions, experimental verification, discussion and analysis, and drawing conclusions. Sometimes the inquiry process needs to extend from in-class to out-of-class In order to record the inquiry process in detail and comprehensively, writing an investigation report is a better form.
In addition, the forms of scientific homework are observation records and bar charts, which teachers can choose according to teaching needs to stimulate students' interest in doing homework.
Third, the evaluation of inquiry-based homework
Evaluation is based on inspection. The purpose of evaluation is to motivate students, make them feel challenges and sense of accomplishment in practical work and have fun in scientific research. Our evaluation methods mainly adopt the following three methods.
1. integral formula. We grade the scientific practice homework according to whether it is completed in time and the quality of the homework, and bring it into the school? Hai Wa picks up shells? In the practice of integral action, students can not only get practical success, but also get expected practical points and increase their sense of accomplishment in homework.
2. Display style. Excellent works in practical work achieve the purpose of motivation through display. We will show students' works or photos, record sheets, diaries, etc. In the science and technology section of the school publicity window, photos of students are attached, so that teachers and students in the school can appreciate their practical achievements and increase their self-confidence and pride.
3. Competition style. In order to ensure the effectiveness of practical homework and enable most students to persist in completing practical homework, we have included some practical homework such as silkworm diary, self-made rubber band power racing activities, moon phase observation and so on. As one of the competition contents of the school science and technology festival. Stimulate students' interest in completing homework through competitions and ensure that homework can be completed at a higher level.
In short, homework is a continuation of classroom teaching and a process of mutual communication between teachers and students. Homework is not only a way for students to check the learning effect, but also a stage for students to show themselves, develop freely and grow constantly under the new curriculum standards. Therefore, in practical teaching, we should pay attention to the design of students' inquiry homework, make students willing to think well, promote the improvement of students' comprehensive ability and enrich the development of quality education.
