This study aims to analyze relations among 3 kinds of latent variables, attitude toward biology laboratory activities, environmental aversion and biology teaching anxiety in 155 elementary pre-service teachers. Thus, this study conducted structural equation modeling based on descriptive statistics, satisfaction of normal distribution conditions and correlation analysis. It was found that the three kinds of latent variables all met normal distribution conditions. Besides, statistically significant correlations were found among measurement variables of each latent variable. The research model was established based on the structural equation analysis results, showing that the more positive attitude they had toward biology laboratory activities, the more positive effect it had on environmental aversion, and attitude toward biology laboratory activities had indirect effect, rathe than direct effect, on biology teaching anxiety through environmental aversion as a mediator. The goodness-of-fit of this model was confirmed through goodness-of-fit indices, such as RMSEA, TLI and CFI, variance estimates and path coefficients. Overall, this study found it important to make positive changes in biology laboratory activities and reduce environmental aversion so that the level of biology teaching anxiety can be maintained low.
Abstract
This study aims to analyze relations among 3 kinds of latent variables, attitude toward biology laboratory activities, environmental aversion and biology teaching anxiety in 155 elementary pre-service teachers. Thus, this study conducted structural equation modeling based on descriptive statistics, satisfaction of normal distribution conditions and correlation analysis. It was found that the three kinds of latent variables all met normal distribution conditions. Besides, statistically significant correlations were found among measurement variables of each latent variable. The research model was established based on the structural equation analysis results, showing that the more positive attitude they had toward biology laboratory activities, the more positive effect it had on environmental aversion, and attitude toward biology laboratory activities had indirect effect, rathe than direct effect, on biology teaching anxiety through environmental aversion as a mediator. The goodness-of-fit of this model was confirmed through goodness-of-fit indices, such as RMSEA, TLI and CFI, variance estimates and path coefficients. Overall, this study found it important to make positive changes in biology laboratory activities and reduce environmental aversion so that the level of biology teaching anxiety can be maintained low.
