The aim of the present study was to re-examine the relationships between achievement goals and perceived purposes of PE, perceived motivational climates, attitudes towards PE teachers and affective outcomes using the 2 ϫ 2 achievement goal framework. Questionnaires were completed by 493 secondary school students (222 males, 262 females, 9 missing) in Singapore. Cluster analysis revealed three distinct clusters that differed significantly in their achievement goals profiles. One cluster consisting of high scores on mastery approach, mastery avoidance and performance avoidance achievement goals was linked to the most positive set of characteristics and outcomes, while the cluster with low achievement goals was linked to most negative characteristics and outcomes. There was another cluster with moderate levels of mastery approach that had relatively positive perceptions and attitudes towards PE. The findings of these three goal profiles provide insight and add knowledge to the existing literature. Research that ignores the independence of the 2 ϫ 2 achievement goal framework may risk making spurious conclusions.

Virtual testing is getting more and more attention in the field of vehicle detection. In order to improve the evaluation accuracy of virtual test data under the condition of far side occupant protection, the paper studies the evaluation method of remote virtual test data accuracy. First, the dynamic responses of 11 simulation and test data are determined by analyzing the basic data under remote conditions. Then, based on CORA and ISO_ The measurement method of TS18571 is used to evaluate the correlation, and the error analysis method is used to analyze the responses with differences in the correlation evaluation results. Finally, the conclusion of the precision evaluation of CORA and ISO measurement methods is obtained through experimental research.
