Abstract
The three teaching objectives of "Middle School Chemistry Experimental Research" course and the background to determine the teaching objectives are introduced. The four teaching links of the teaching implementation process, namely collective lesson preparation, group guidance, grading and summary are also introduced. In the course implementation, the concept of "student-centeredness" and "learning-centeredness" are implemented to improve students' learning ability. During the course implementation, a "learning community" based on group cooperation is constructed to cultivate students' sense of teamwork. Formative assessment and summative assessment are used to assess learning outcome, 147 students' total score, individual score distribution and course goal achievement degree were calculated and analyzed with Excel. The results show that the degree of achievement of curriculum objectives 1, 2, and 3 are 0.84, 0.85, and 0.84, respectively, and the score distribution of 147 students basically conforms to the normal distribution. In addition, the standard deviations of the three items of teaching aids production, digitized experiment and experimental improvement of 147 students were 1.34, 1.35 and 1.04, respectively. The implementation of the course has achieved good results, and the implementation method of the course and the assessment method of the learning outcome have certain reference significance to the implementation and assessment of other similar courses.
Highlights
The three teaching objectives of "Middle School Chemistry Experimental Research" course and the background to determine the teaching objectives are introduced
The course objectives are determined in accordance with the graduation requirements in the "Secondary Education Professional Certification Standards" (Level 2)
In order to make "Middle School Chemistry Experimental Research" course can effectively support the graduation requirements, we insist on the concept of "student-centeredness" in the course implementation process [1,2,3], build "learning communities" based on group cooperation [4], highlight the transformation from "teaching-centeredness" mode to "learning-centeredness" mode.

Summary
"Middle School Chemistry Experiment Research" is a professional practical course for undergraduate students majoring in chemistry. The teaching objective of this course is to cultivate students' middle school chemistry experiment research ability, communication skills, teamwork spirit and sense of innovation. Article 7 of the graduation requirements [Learn to reflect] requires graduates to have a preliminary grasp of reflective methods and skills, and have a certain sense of innovation. In order to make "Middle School Chemistry Experimental Research" course can effectively support the graduation requirements, we insist on the concept of "student-centeredness" in the course implementation process [1,2,3], build "learning communities" based on group cooperation [4], highlight the transformation from "teaching-centeredness" mode to "learning-centeredness" mode. In order to test the effect implementation, we evaluate "course-level learning outcome" by means of score statistical analysis and assessment of the achievement of Education Journal 2021; 10(5): 175-181 course objectives. Teaching aids making, digitized experiments and experiment improvement, research report, experiment operation video, and reflection report on the three projects
