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

Posted on by Troels Gannerup Christensen - Læst 10 gange

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 – Development of Computational Thinking Scale: Validity and Reliability Study

Posted on by Troels Gannerup Christensen - Læst 147 gange

eric.ed.gov har udgivet: Computational thinking is a way of thinking that covers 21st century skills and includes new generation concepts such as robotics, coding, informatics and information construction. Computational thinking has reached an important point especially in the field of science in line with the rapid developments in technology. Robotics applications, software-based activities, STEM (Science, Technology, Engineering, Math) education and problem-based studies are some of the areas where this thinking is used. In this study, which is based on this point, it is aimed to develop a scale for computational thinking. Exploratory sequential design, one of the mixed research methods, was used in the study. First of all, a detailed literature review was conducted and needs analysis was carried out. This study consists of two stages. In the first stage,… Continue Reading →
