Peer assessment is an effective evaluation method for online courses, which can solve the problem of large-scale online learning evaluation and improve the evaluation efficiency. Aiming at the problem of matching in peer assessment, a reviewer matching recommendation strategy based on training is proposed. According to the analysis of training data, it mines the evaluation characteristics of learners and generates the peer assessment recommendation list. The practice result shows that this strategy can ensure the effectiveness and reliability of peer assessment and promote learners' learning introspection

In view of the immature evaluation of mixed teaching quality and the lack of suitable training and evaluation standards for applied talents, taking the evaluation of students' learning ability and comprehensive quality in Applied Colleges and Universities as the background, this paper explores the construction of student-centered teaching quality evaluation index system with ability training as the main line, quantifiable learning process and easy evaluation, starting with the in-depth analysis of the typical activities of teachers and students in the process of pre-class preparation, in-class implementation and after-class feedback of mixed teaching. At the practical level, taking the students majoring in Internet of things engineering as the research object, the 2020 students are included in the experimental group and the 2019 students as the reference group. Through the analysis of the significance of the final results of the two groups of students and the questionnaire survey on the course satisfaction of 2020 students, it is verified that the constructed teaching evaluation system can effectively stimulate students' learning interest and improve teaching quality. Using the teaching process data of the experimental group collected on the cloud platform, the weight reliability of the evaluation index system is analyzed by SPSS software, which shows that the evaluation system has high reliability. The construction of mixed teaching evaluation index system provides new ideas and reference value for peers to further carry out relevant research from the theoretical and practical levels.

Drowning accidents occur frequently among teenagers, and drowning prevention safety education has become one of the education work in primary and secondary schools. Due to the high temperature in summer in China, students often go to the natural waters to play and swim, which is prone to drowning. In view of the emergence of more and more drowning cases, an drowning prevention system is made to protect people's life safety to a certain extent.

To strengthen the cultivation of computer system abilities in local universities, the teaching of Operating System curriculum has been reformed and explored in this paper. First, the origin of computer system ability cultivation has been reviewed, the characteristics of the implementation process in local universities are analyzed. Then, the existing problems in training computer system abilities in the current Operating System curriculum are discussed. Finally, the reform measures of Operating System curriculum teaching are proposed in terms of four aspects which are course content, experiment teaching, teaching methods and course assessment. The teaching practice of Operating System curriculum shows that the proposed reform measures are of great significance to improve the cultivation level of computer system ability for students in local universities

The evaluation of ideological and political education teaching of computer course has some problems, such as subjectivity and one-sidedness. The Delphi method is used to screen out the evaluation index of ideological and political teaching of computer course, and construct the evaluation system of ideological and political education teaching of computer course. The Analytic Hierarchy Process(AHP) is used to calculate the evaluation index weight of ideological and political education teaching of computer course. Finally, the teaching effect is quantitatively analyzed and evaluated through the ideological and political education teaching cases of computer course. According to the analysis results, feasible suggestions are put forward for the effective development of ideological and political education teaching of computer course.

In view of the problems in current Software Testing course affecting students’ability training, such as theoretical knowledge lag, unsatisfactory experimental effect, lack of project experience and so on, this paper puts forward some reform measures related to theory, practice and project teaching based on the OBE concept, to cultivate students' practical ability and achieve the applied talent training.

At present, artificial intelligence, block chaining, big data and other technologies set off the fourth industrial revolution. The persistence of COVID-19 has accelerated the promotion of digital and intelligent applications, and the big data has increased the difficulty of people's rapid access to demand, thus the recommendation system has been widely applied. The recommendation system has also been applied in the mainstream e-commerce platform in the book field. In this paper, through the collaborative filtering recommendation algorithm based on Mahout framework, combined with knowledge classification and user interest, a collaborative filtering recommendation algorithm based on knowledge classification and user interest is proposed. Through experimental analysis, the algorithm provides more refined personalized recommendation and higher recommendation quality.

In order to adapt to the new requirements of the intelligent era for talents and change the boring teaching situation of C Language course, the interdisciplinary characteristics of Internet of Things application technology specialty are combined. This paper takes intelligent robot as a platform and integration of curriculum projects as a carrier, reconstructs the framework of knowledge and skills, so that the learning process of knowledge is closer to students' cognitive law, and the training process of ability is more in line with the law of professional ability development. It aims to improve the students' ability of integrating knowledge and skills, human-computer interaction ability, and also plays a role in paving the way for the follow-up professional core courses

As a compulsory course for electrical students,Power Electronic Technologyhas strong practical requirements. However,there are some problems in traditional practical teaching, such as lack of test equipment and complex process, which lead to poorteaching effect. As a kind of simulation software, the introduction of MATLAB into the teaching process can make up for the short-comings of traditional practical teaching. Take the "simulation experiment of single-phase half wave controllable rectifier circuit" forexample, this paper analyzes the advantages and application process of the application of MATLAB in the practical teaching ofPow-er Electronic Technology, and proves that the application of MATLAB in the practical teaching ofPower Electronic Technologyisbeneficial to the improvement of teaching quality and practical efficiency.
