WebThe present contribution provides a conceptualization of teacher emotions rooted in appraisal theory and draws on several complementary theoretical perspectives to create a conceptual framework for understanding the teacher emotion–student outcome link based on three psychological mechanisms: (1) direct transmission effects between teacher and … Webfaces has no effect (other than increasing absorption losses) on the optical properties of the lens. In a Fresnel (point focus) lens the bulk of material has been reduced by the extraction of a set of coaxial annular cylinders of material, as shown in Figure 1.
