Supplemental Materials Response to Instruction in Preschool: Results of Two Randomized Studies with Children At Risk of Reading Difficulties by C. Lonigan & B. M. Phillips, 2015, Journal of Educational Psychology http://dx.doi.org/10.1037/edu0000054 Appendix S1 Classroom Observations: Frequency and Quality of Instructional Activities As part of the larger project in which this study was embedded, we observed preschool classrooms three times during the school year using a modified version of the Teacher Behavior Rating Scales (TBRS; Landry, Crawford, Gunnewig, & Swank, 2000). The original TBRS included 50 items concerning the quantity and quality of specific teacher behaviors and classroom characteristics that are grouped into 12 subscales. Six subscales relate to overall classroom characteristics or general teaching behavior (e.g., teacher sensitivity, discipline, learning centers), and six subscales relate to specific instructional activities (e.g., book reading, print activities, phonological awareness). Items on each subscale are rated on a 4-point (1 = rarely occurred, 4 = often occurred) quantity scale and 3-point quality scale. The revised TBRS included 12 additional items for phonological awareness activities, including a rating of phonological awareness activities to indicate whether the instruction was explicit (i.e., instructional activities that include modeling and explanation of key terms and concepts, use of scaffolding and corrective feedback when appropriate) or implicit (i.e., simple exposure to different sound patterns and teachers’ commenting about shared sounds between words [e.g., “these words start with the same sound”]). The TBRS-R was completed in the classrooms in the larger study by trained observers who observed classrooms for a minimum of two hours and a maximum of four hours, depending on the structure of the preschool (mean duration = 168.2 minutes; SD = 25.5). Analyses of differences of TBRS-R scores between preschools that were a part of the school district’s Title I program and other local preschools that were not affiliated with the school district used all available observations. Analyses were conducted as mixed models in SPSS (Version 19) using classroom and school as random factors (i.e., observations were nested within teachers’ classrooms that were nested within schools). Descriptive statistics and effect sizes are shown in Table S1. The classrooms in the district’s Title I preschools had a higher frequency, quality, or both for oral language activities, print knowledge activities, phonological awareness activities, and math activities than did classrooms in private preschools, and classrooms in the district schools had a higher quality of center activities, more small-group instruction, and more team teaching than did classrooms in the private preschools.
