Survey of Classroom Use of Representations: Development, Field Test and Multilevel Analysis.

摘要: Because of the multimodal nature learning, doing and reporting science, it is important that students learn how to interpret, construct, relate translate scientific representations or, in other words, develop representational competence. Explicit instruction about needed foster students’ competence classroom. However, only a handful studies have surveyed are actually used science classes. This might be because fact economical instruments for assessing use classrooms not available. To bridge gap, an instrument was developed, field-tested biology classes with 175 931 students, respectively, analysed using exploratory (multilevel) confirmatory factor analyses. Results supported six scales 21 items at individual classroom levels covering following dimensions: (1) interpretation visual representations, (2) construction (3) texts (verbal representations), (4) symbolic (5) number terms class, (6) extent which active social knowledge possible class. The showed satisfactory discriminant validity reliability each level. Further applications this researchers teachers discussed.
