Preservice Observation in Special Education: A Validation Study.

Advancing teacher candidates' overall competence through use of valid teacher observation systems should be an essential element of teacher preparation. Yet, the field of special education has not provided observation protocols designed specifically for preservice teachers that are founded in theoretical perspectives and research on effective instruction for students with learning and other high-incidence disabilities (SWDs). To address this need, a group of researchers in special education teacher preparation and measurement developed the Preservice Observation Instrument for Special Education (POISE). The POISE is an observation system rooted in effective special education practices that support the growth of preservice teachers who will serve SWD across instructional settings. The purpose of this article is to report on the development and psychometric properties of the POISE. Specifically, we employed Kane's argument-based validity approach to frame each stage in the development process of the POISE. We conducted two phases of content validation activities, development activities, and a pilot study to assess the degree to which scores from POISE provided evidence for the scoring, generalizability, and extrapolation inferences. In the end, the POISE represents a promising observation instrument for the development of special education teacher candidates.

Danielson's Framework for Teaching: Convergence and Divergence With Conceptions of Effectiveness in Special Education.

Danielson's Framework for Teaching (FFT) is currently used in more than 20 states to inform teacher evaluation and professional learning. To investigate whether FFT promotes instruction that appropriately responds to the needs of students with learning disabilities, we conduct a systematic content analysis of the instructional approach emphasized in the FFT's Instructional Domain (Domain 3) of Danielson's FFT. We frame our study using cognitive load theory and research regarding effective instruction for students with disabilities. We end by discussing implications regarding the evaluation and development of effective teaching for students with learning disabilities.

Exploring How Initial Response to Instruction Predicts Morphology Outcomes Among Students With Decoding Difficulties.

Children with weak decoding skills often struggle to learn multisyllabic words during reading instruction. The primary purpose of this study was to investigate the extent to which initial response to morphological awareness instruction, along with specific language and cognitive variables (i.e., phonological awareness, rapid naming, orthographic knowledge/awareness, verbal comprehension, working memory), predicts responsiveness to morphological awareness instruction for third-grade students who were at risk for reading disabilities. Thirty-nine third-grade students with decoding deficits were assessed on five independent variables identified as critical predictors of future performance on morphological tasks. A series of regression analyses showed that initial response to instruction, compared to other cognitive and language variables, predicted the most variance in students' morphological skills with prefixes. Furthermore, two cognitive variables, verbal working memory and comprehension, were predictive of performance on morphological tasks after accounting for initial response to instruction. Findings from this study suggest that students with decoding deficits may benefit from morphological instruction and those who demonstrate low response to initial morphological instruction or have weak verbal comprehension and verbal working memory abilities could be risk for failing to acquire morphological instruction as expected.
