【Abstract】 Facet theory was developed by Louis Guttman as a systematic approach for coordinating theory and research by means of formal a priori definitions of the domain of the study and of the variables that comprise the domain. And it serves as the basis for building a unified conceptual framework for the research. The main purpose of this study is to develop a new measurement instrument called Teaching Efficacy Scale (TES) applying the facet theory approach. Based on the findings of earlier studies and the results of the interviews with10 middle school teachers, a two-facet mapping sentence for the teaching efficacy concept was designed. Based on the structures of the two facets, 40 items for measuring the teaching efficacy were developed and a primary teaching efficacy scale (TES) was constructed. Based upon the responses from 162 middle school teachers to the scale and using a combination of traditional reliability analysis and smallest space analysis (SSA), nine ambiguously located items in the SSA maps were removed and a formal 21-item teaching efficacy scale emerged. Using a formal TES and the mapping sentence, hypotheses regarding the relations between the definitional framework and empirical observations were tested through SSA and the confirmatory factor analysis of the data collected from a sample of 530 middle school teachers. The results demonstrate strong support for the definitional system and show a clear radax structure of teaching efficacy. The 2-dimension configurations of Facet A (designated as tasks) and Facet B (designated as cognation resources) and the 2-dimensional combination configuration of Facet A and Facet B had very small coefficients of alienation (< .14), suggesting that the configurations were very reliable. The region index of the configurations of Facet A, Facet B and the combination configuration of Facet A and Facet B are very large (> .9), suggesting that the facet definitions were strongly supported and the theoretical constructions were empirically confirmed. The items designed by the facet theory approach empirically distinguish the distinct character-based components of teaching efficacy. Facet A could be partitioned further according to the modality (knowledge transfer, organization and management of classroom and behavior and moral education of student) and Facet B could be partitioned further according to polarizing (the quality ability, student feedback, positive experience and emotionality). The combined 2-dimensional configuration of Facet A and Facet B turned out to be a radex presentation. By using the definitional mapping sentence of facet Theory and SSA, the multidimensional theory and structural proposal were formed, which was further tested by confirmatory factory analysis (CFA). The indices thus obtained indicated a good fit between the data and the hypothesized factor structure. All parameter estimates were acceptable. We draw three conclusions. 1)The Teaching Efficacy Scale can be defined from two facets. Facet A (tasks) consisted of three elements corresponding to three factors and Facet B (cognitive sources) consisted of four elements corresponding to four factors. 2) The newly developed TES with two facets has high reliability and validity, which can be used as an evident instrument to measure teaching efficacy. 3) The teachers of secondary schools are mainly concerned with students’ knowledge. When evaluating the teaching effects on their own, the teachers of secondary schools tend to manifest multiple perspectives drawing on similar cognitive resources.更多还原
