Though the benefits of using math manipulatives has been reported, there seems to be a disconnect between the benefits of manipulative use and the number of teachers integrating them in their lessons on a daily basis. In this study a total of 22 regular education teachers in kindergarten through sixth grade and five learning support teachers in grades first through sixth from a rural elementary school were given a survey instrument to test its validity and reveal some trends in teachers’ views on manipulative use as well as possible causation for their views. Findings from the study show that though many teachers feel comfortable using and… Continue Reading →

ABSTRACT A Bayesian IRT-model approach was used to investigate the validity and reliability of student perceptions of teaching quality. Furthermore, the student perceptions were compared with ratings of teaching quality by external observers. Grade 4 students (n = 675) filled out a questionnaire that was used to measure their opinions about the lessons of their teachers. Three lessons of 39 teachers were recorded and rated by 4 raters. The analyses showed that student perception and lesson observation scales fit best in… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT We wanted to assess the quality of research conducted by Dutch secondary education teachers. We therefore needed to investigate the criteria for evaluating teacher research. The research timeline of this study covered four school years. We analyzed research reports and evaluation forms. We found that five quality criteria are useful for assessing teacher research. We made concrete operationalizations of these five criteria and their indicators. We found that successfully conducted teacher research contributes to professional and school development. Its contribution to professional development is greater and more concrete than to school development. Link til kilde

eric.ed.gov har udgivet: The purpose of the research is to develop a valid and reliable attitude scale that can measure the attitudes of math and science teachers (315) and teacher candidates (105) towards mistakes and instant feedback. In the validity studies, the exploratory factor analysis was made with the SPS1S 8.0 package program after that the confirmatory factor analysis was made with Lisrel 8.8 software. To develop the scale; 1. Creation of Item Pool, 2. Obtaining Expert Opinion, 3. Creation of Pre-Trial Form, 4. Factor Analysis is made. According to factor analysis; Kaiser Meyer Olkin (KMO) rate; 0.808; Bartlett test result: 2148,354; Cronbach alpha reliability coefficient for the whole scale: 0.829. According to confirmatory factor analysis: Root Mean Square Error of Approximation (RMSEA) 0.022 (<0.05); p-Value for Test of Close… Continue Reading →

Abstract Ontologies play an important role as knowledge domain representations in technology-enhanced learning and instruction. Represented in form of concept maps they are commonly used as teaching and learning material and have the potential to enhance positive educational outcomes. To ensure the effective use of an ontology representing a knowledge domain it needs to be validated. In this paper a previously presented validation methodology for concept maps is exemplified. Two different types of concept map validity are distinguished, referring… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT Research on teacher knowledge has been criticised for taking too narrow a view on expertise. Therefore, teacher competence frameworks have been developed that are closely related to professional demands. Their practice-oriented conceptualisations have led to innovative measures with situative demands. However, there is still a lack of knowledge on whether these frameworks are actually suited to map teacher growth. This study investigated whether two components of teacher competence, Action-related (AC) and Reflective Competence (RC), can be differentially fostered through specific interventions in early childhood mathematics education. We designed two professional development programmes with a focus on AC and RC and implemented them in a randomised controlled experiment with 170 teachers. Overall, we found that AC, RC, and professional… Continue Reading →
