This supervision instrument is meant to measure teaching effectiveness, learning, and content mastery. It will be used during classroom observations in reading classes at the author's school. The instrument is divided into sections that evaluate goals and expectations, assessment, instructional practices, learning environment, curriculum quality, preparation for student needs, and evidence of differentiation. The last section specifically looks at phonics instruction, which the school's data identified as an area of need. The form allows observers to take notes on these elements and provide feedback to improve instruction in reading, particularly phonics skills. The overall goal is to increase student success in reading through more explicit and differentiated phonics teaching.
