With the development of computer technology and the improvement of physical education teaching evaluation method, evaluation of sports courses can be realized by the computer. In the background of new education reform, teaching methods have undergone a lot of change. Physical education belongs to the action exemplary teaching. In the process of physical education, it needs to achieve the real-time information exchange between teachers and students which can improve teaching efficiency and effect. Based on this, the paper designs and develops the B / S and C / S joint computer frame mode of physical education curriculum assessment and established the mathematical model of the physical education curriculum assessment using the comprehensive fuzzy evaluation theory. Finally, the paper prepares programming language of the physical education curriculum assessment system through java programming and the expert weight coefficient of PE curriculum evaluation. It also designs computer evaluation system of physical education curriculum assessment which provides a theoretical reference for PE curriculum assessment system.

The analysis of heart rate variability (HRV) is an important diagnostic method for detection and assessment of cardiac abnormalities. The availability of complete computer frameworks that can aid researchers in the field of HRV analysis is limited due to the large number of different feature extraction methods. A recently developed framework for feature extraction from cardiac rhythm called HRVFrame is promising, because it allows a user to access more than 40 implemented linear and nonlinear methods. The aim of this paper is to provide a more detailed overview of this framework and all of its capabilities and recent extensions. Additionally, the aim is to encourage the use of HRVFrame as a free and open-source tool for developing medical applications based on java programming language. A comparison of the framework with existing solutions for cardiac rhythm analysis is provided.

Automated marking of multiple-choice exams is of great interest in university courses with a large number of students. For this reason, it has been systematically implanted in almost all universities. Automatic assessment of source code is however less extended. There are several reasons for that. One reason is that almost all existing systems are based on output comparison with a gold standard. If the output is the expected, the code is correct. Otherwise, it is reported as wrong, even if there is only one typo in the code. Moreover, why it is wrong remains a mystery. In general, assessment tools treat the code as a black box, and they only assess the externally observable behavior. In this work we introduce a new code assessment method that also verifies properties of the code, thus allowing to mark the code even if it is only partially correct. We also report about the use of this system in a real university context, showing that the system automatically assesses around 50% of the work.

This paper presents an interactive, user-friendly tutoring system, which can be used to enhance students' understanding of the principles behind data structures. The system has the capability to display data structures graphically as well as providing the facility to allow users to perform the basic operations on the data structure generated. An animation-based approach has been developed to provide a step-by-step illustration of how various traversal techniques are performed in the context of binary search and AVL trees data structure. The system has a tutorial mode incorporating exercises, where students can learn basic concepts operations associated with each data structure. The evaluation was carried out by computer science undergraduate students in the School of Computing and Mathematics. It is generally acknowledged that the system was very useful in teaching students about data structures. This system can be used as an effective supplement to traditional teaching methods.
