EXAMINING TEACHERS�� STRUGGLES AS THEY ATTEMPT TO IMPLEMENT DIALOGICAL INTERACTION AS PART OF PROMOTING MATHEMATICAL REASONING WITHIN THEIR CLASSROOMS     

Recai Akkus  Brian Hand 《International Journal of Science and Mathematics Education》2011,9(4):975-998

This study examines the changes in teaching practices during the implementation of a pedagogical model called the mathematics reasoning approach (MRA), which was founded on 2 critical areas in mathematics, problem solving, and writing to learn. Three algebra teachers implemented the approach with their classes, which were divided into control (traditional) and treatment (student-centered approach) groups, with their levels of implementation measured by the Reformed Teaching Observation Protocol (RTOP) instrument. The implementation of the model resulted in positive changes in teachers’ pedagogical practices and yet showed the struggles they faced. In the control classes (traditional classes), the level of teaching remained the same throughout the study, whereas in the treatment classes (MRA classes), a significant improvement in the level of teaching was observed. Even though the teachers’ implementation levels differed from each other, the patterns of the change for all 3 teachers showed similarities; that is, their MRA teaching level was initially equivalent to their control teaching, but as the semester progress, there was a separation between the 2 approaches. This separation between the 2 approaches appeared to be dependent upon the pedagogical area on which the teacher put emphasis. The skill of questioning seemed to be 1 which each teacher first changed.  相似文献   

Aligning Teaching to Learning: A 3-Year Study Examining the Embedding of Language and Argumentation into Elementary Science Classrooms

How can classrooms become communities of inquiry that connect intellectually challenging science content with language-based activities (opportunities to talk, listen, read, and write) especially in settings with diverse populations? This question guided a 3-year mixed-methods research study using the Science Writing Heuristic (SWH) approach in cooperation with 2 universities, area education agencies, 6 school districts, 32 elementary teachers, and over 700 students each year. The participating teachers engaged in a yearly summer institute, planned units, implemented this curriculum in the classroom, and contributed to ongoing data collection and analysis. Findings demonstrate that critical embedded language opportunities contribute to an increase in student Iowa Tests of Basic Skills (ITBS) scores in science and language based on level of implementation particularly for elementary students who receive free and reduced lunch (an indicator of living at the poverty level).  相似文献   

Comparing an Inquiry‐based Approach known as the Science Writing Heuristic to Traditional Science Teaching Practices: Are there differences?     

Recai Akkus  Murat Gunel  Brian Hand 《International Journal of Science Education》2013,35(14):1745-1765

Many state and federal governments have mandated in such documents as the National Science Education Standards that inquiry strategies should be the focus of the teaching of science within school classrooms. The difficult part for success is changing teacher practices from perceived traditional ways of teaching to more inquiry‐based approaches. Arguments are often made about the effectiveness of these traditional strategies. The purpose of this study was to compare the effectiveness of the inquiry‐based approach known as the Science Writing Heuristic approach as a treatment to traditional teaching practices on students' post‐test scores in relation to students' achievement level and teacher's implementation of the approach. A mixed‐method research approach was used to analyze the teacher observational data and students' test results. The major findings of this study are that the quality of the implementation does have an impact on student performance on post‐test scores and that high‐quality implementation of the Science Writing Heuristic approach has significant advantages in closing the achievement gap within science classrooms.  相似文献   

A new nonautonomous version of Chua's circuit: Experimental observations     

Recai Kiliç  Ö. Galip Saraço?lu 《Journal of The Franklin Institute》2006,343(2):191-203

In this study, a novel nonautonomous version of autonomous Chua's circuit is presented. The proposed nonautonomous version of Chua's circuit was designed by placing a sinusoidal source to the inner structure of the nonlinear resistor, namely, Chua's diode. The circuit's chaotic dynamics have been investigated by PSpice simulations and laboratory experiments.  相似文献   

The influence of pedagogical beliefs on technology acceptance: a structural equation modeling study of pre-service mathematics teachers     

Gurer  Melih Derya  Akkaya  Recai 《Journal of Mathematics Teacher Education》2022,25(4):479-495

Pedagogical beliefs are a critical factor in terms of integrating technology into teaching, but very few technology acceptance models (TAMs) have considered them. Hence, this study aims to extend the TAM by incorporating pre-service teachers’ conception of teaching and learning. The revised model examined the influence of pre-service mathematics teachers’ constructivist and traditional pedagogical beliefs on their technology acceptance through perceived ease of use, perceived usefulness, attitude toward technology, and behavioral intention to use. Survey data were collected from 714 pre-service mathematics teachers in Turkey and analyzed through path analysis. The results showed that pre-service mathematics teachers’ pedagogical beliefs were more constructivist-oriented than traditional-oriented, and constructivist beliefs had a significant influence on the components of the TAM. On the other hand, pre-service teachers’ traditional-oriented beliefs did not influence their perceived usefulness of and attitudes toward technology but had positive effects on perceived ease of use. Implications for pre-service mathematics teacher education were discussed.
