Eric.ed.gov – Instructional Interactions of Kindergarten Mathematics Classrooms: Validating a Direct Observation Instrument

eric.ed.gov har udgivet: In this paper, the authors report research focused directly on the validation of the Coding of Academic Teacher-Student interactions (CATS) direct observation instrument. They use classroom information gathered by the CATS instrument to better understand the potential mediating variables hypothesized to influence student achievement. Their study’s purpose is to gather the kinds of validity evidences that match the proposed interpretations and uses of the CATS instrument (Kane, 2008; Messick, 1995). Therefore, they first explore the content aspect of construct validity by collecting information about the content relevance and representativeness of the observation instrument (Messick, 1995). Second, concerned about the consistency of the observation data collected across a number of independent observers, they measure inter-observer agreement. Finally, they focus on the criterion-predictive aspect of construct validity and investigate… Continue Reading

Eric.ed.gov – The Alignment of easyCBM[R] Math Measures to Curriculum Standards. Technical Report #1002

eric.ed.gov har udgivet: The purpose of this study was to examine the alignment of the easyCBM[R] mathematics benchmark and progress monitoring measures to the National Council of Teachers of Mathematics “Curriculum Focal Points” (NCTM, 2006). Based on Webb’s alignment model (1997, 2002), we collected expert judgments on individual math items across a sampling of forms for grades K, 1, and 3-8. We found generally strong alignment across grade levels, focal points, and test forms between the easyCBM[R] mathematics items and the content standards. Example of Rater Materials is appended.

Eric.ed.gov – Where Is the Math in Science Olympiad? Aligning Mathematics Standards to Science Olympiad Events

eric.ed.gov har udgivet: Science Olympiad (SO) is a national non-profit organization which holds science competitions for students in grades 7-12 within 50 states with each event aligned to Next Generation Science Standards (NGSS, 2010). The purpose of this article is not only to align the Common Core State Standards in Mathematics (CCSSM) with Science Olympiad events, but also to determine Webb’s Depth of Knowledge Levels (DOK) within the mathematics content. This alignment was achieved by utilizing a content analysis and the Depth of Knowledge alignment processes (Webb, 1999). The findings in this study indicate there are a significant number of SO events that are aligned to the CCSSM with high levels of Depth of Knowledge within the Division B (grades 6-8) and C (grades 9-12) events.
