This study included teachers and students from 32 high schools in Oklahoma (16 experimental classrooms; 16 control classrooms). Students were enrolled in an APT course during the 2004-2005 school year. The experimental design used was a posttest only control group; unit of analysis was the classroom. One-way analysis of variance (ANOVA) was used to test the study’s null hypothesis. The measure of students’ technical competence did not reveal results that held statistical significance… Continue Reading →

eric.ed.gov har udgivet: The Public Broadcasting Service (PBS) sought to build on the strengths of high quality professional development through an online venture funded under the U.S. Department of Education’s Ready To Teach (RTT) program. PBS TeacherLine was designed to provide high-quality, facilitated online professional development for K-12 teachers nationwide. Through PBS TeacherLine, more than 20,000 educators have participated in 90 online, facilitated courses in reading, mathematics, science, instructional strategies, instructional technology, and curriculum mapping. To what extent has PBS TeacherLine been successful in creating an online model of teacher professional development that gets to the heart of education needs–impacting teacher beliefs, classroom instruction, and student learning? This paper presents the results from one component of the comprehensive external evaluation of PBS TeacherLine: an experimental study that unfolded in the… Continue Reading →

ABSTRACT A growing literature on within-study comparisons (WSC) examines whether and in what context nonexperimental methods can successfully replicate the results of randomized experiments. WSCs require that the experimental and nonexperimental methods assess the same causal estimand. But experiments that include noncompliance in treatment assignment produce a divergence in the causal estimands measured by standard approaches: the experiment-based estimate of the impact of treatment (the complier average causal effect, CACE) applies only to compliers, while the nonexperimental estimate applies… Continue Reading →

eric.ed.gov har udgivet: Research indicates that preschool children need to learn pre-math skills to build a foundation for primary- and secondary-level mathematics. This paper presents the results from the early stages of a pilot mathematics program implemented in Cordillera, Paraguay. In a context of significant gaps in teacher preparation and pedagogy, the program uses interactive audio segments that cover the entire preschool math curriculum. Since Paraguayan classrooms tend to be bilingual, the audio and written materials use a combination of Spanish and Guaraní. Based on an experimental evaluation since the program’s implementation, we document positive and significant improvements of 0.16 standard deviations in standardized test scores. The program helped narrow learning gaps between low- and high-performing students, and between students with trained teachers and those whose teachers lack formal training… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: Abstract Understanding the abstract principles of statistical experimental design can challenge undergraduate students, especially when learned in a lecture setting. This paper presents a concrete and easily replicated example of experimental design principles in action through a hands-on learning activity for students enrolled in an experimental design course. The activity, conducted during five 50-minute classes, requires the students to work as a team to design and execute a simple and safe factorial experiment, and collect and analyze the data. During three in-class design meetings, the students design and plan all aspects of the experiment, including choosing the response and explanatory variables, making a list of needed supplies, creating a randomization schedule with the Minitab DOE utility, and writing a statistical… Continue Reading →
