Innovation of Physical Education and Health Curriculum Teaching Models in Colleges and Universities in the Digital Era and Its Contribution to Students’ Core Literacy

Abstract

Physical education and health curricula in colleges and universities are obsolete, and there is an urgent need to innovate teaching models and methods. To achieve innovation in physical education and health teaching, this paper utilizes cutting-edge information technology like motion recognition to construct a physical education and health data monitoring model. Firstly, the positional relationship between coordinate systems is determined, and the established coordinate system is used to describe the orientation and position of human postural joints, and the rotation matrix is used to define the rotation from the global coordinate system to the current orientation of the local coordinate system of bones. A human motion joint skeletal chain model is created that has 21 bones and 21 joints. The joint pose solution method is proposed, and the human kinematic model is constructed by combining robot ortho kinematics and coordinate transformation. A position estimation algorithm combining inertial navigation and a human kinematics model has been designed. After analyzing the performance of the recognition model, analyze the effects of its application on the innovation of college physical education courses. It is found that the model in this paper monitors the heart rate data with an error of only 3 or less, and the accuracy of human movement recognition on the MHealth and PAMAP2 datasets is 97.38% and 96.63%, respectively, and the learning ability is optimal. After one semester of innovative mode teaching and the use of a physical education and health data monitoring model, the mean values of physical education and health knowledge, physical education behavior, physical fitness and health, motor skills, and physical character of the experimental class were 35.77, 25.53, 25.04, 35.73, and 31.56 points higher than those of the control class, respectively. Motivation, skill acquisition, after-school sports, and sports concern were significantly higher in the experimental class, with scores of 5.66, 6.71, 5.61, and 3.65 points higher than the control class. This paper’s innovative teaching mode and model have been effective in improving teaching quality and stimulating students’ sports and health habits.
