153. Academic Self-Concept, Perceptions of the Learning Environment, Engagement, and Learning Outcomes of University Students: Relationships and Causal Ordering

Author

Guo, Jian-Peng, Yang, Ling-Yan, Zhang, Juan, and Gan, Ya-Juan

Abstract

Two studies were conducted to examine the relationships among university students' academic self-concept, perceptions of the learning environment, engagement, and learning outcomes (academic achievement, generic skills development, and learning satisfaction). Study 1 (N = 1,502) adopted a cross-sectional design and supported a model showing that engagement mediated the effects of academic self-concept and perceptions of the learning environment on generic skills development and learning satisfaction. It was also found that academic self-concept directly predicted academic achievement and generic skills and that perceptions of the learning environment directly predicted learning satisfaction. Study 2 (N = 2,069) adopted a longitudinal design involving three waves of data collection with a 1-year interval (freshman, sophomore, junior). The results of study 2 replicated the findings of study 1 and supported a reciprocal effects model showing that prior academic achievement predicted subsequent self-concept which in turn determined future achievement even with prior achievement partialed out. These findings contribute to developing a finer-grained model of higher education student learning.

Abstract

Abstract At present, most studies of anchorage techniques for earthen architecture ruins are conducted so as to improve the anchor force, however, the damage caused to the ruins by anchor reinforcement has not been fully considered in practice and no special anchor technique has been applied to reinforce the small sliding mass. This paper summarizes the application and R&D of anchor rod techniques as applied to the protection of the Gaochang Ruins, Turpan, in China. Based on the reinforcement of the small sliding mass of the earthen historical ramparts, a new type of Geotechnical Filament Anchor (GFA) is designed. By changing six parameters, including anchorage length (L), GF thickness (H), bore diameter (D), slurry strength (S), GFA surface state (R) and inclination Angle (A), the tensile strength, failure mode, load displacement (P-S) relationship and strain (ζ-L) distribution characteristics are studied, and corresponding analysis is performed on the test data and phenomena. (1) A formula for the design value of the anchorage force N is presented. (2) Combining the data on the strain distribution at the GF-slurry interface under the action of N, the shear stress distribution model of the anchorage system is obtained. (3) Taking into account the soil mechanical properties of the above-mentioned ruins, the shear stress diffusion coefficient (α) is conceptualized, the formula for the shear strength of the grouting material is obtained, and the allowable ranges of L, D, H, R, and S determined. A new design is proposed for the application of anchorage techniques to earthen ruins in the context of protection of cultural relics, which promotes the design and calculation method described in this paper.
