This study attempts to identify latent sub-groups based on teachers' reading self-determination,
and to figure out the characteristics of the subgroups. This study also examined the differences in
reading motivation, teacher efficacy, and instructional strategies in reading class, depending on the
types of autonomy motivation.
A total 206 of elementary and secondary school teachers were collected and analyzed. Latent Class
Analysis(LCA) and Analysis of Variance(ANOVA) were employed to analyze the data, using SPSS
19.0 and Mplus programs. The results were as follows:
First, three subgroups within the sample were found to be qualitatively different as they presented
“high intrinsic-high extrinsic regulation” group, “high-intrinsic regulation” group, and “low-intrinsic
regulation” group. Second, except avoidance, reading motivation (measured by MRQ; Baker &
Wigfield, 1999) and reading activities (e.g. amount of time spend in reading, ) were found to be
higher in higher intrinsic groups than in low intrinsic group. Third, teachers who have more
autonomous motivation(i.e. higher intrinsic regulation groups) showed higher teacher efficacy and
more frequent use of instructional and assignment strategies in reading class.
