Eighteen primary teachers across three conditions (Representational Fluency, Representational Agency, Comparison) received two days of training around an inquiry unit on plate tectonics replete with representations. The Representational Agency group also received training around the semiotic and material affordances of representations while the…

Mathematical reasoning involves comprehending mathematical information and concepts in a logical way and forming conclusions and generalizations based on this comprehension. Computer-based learning has been incorporated into classrooms across the country, and specific aspects of technology need to be studied to determine how programs are…

The aim of this study is to investigate effects of the guiding materials developed based on the "fire context" and related to "expansion-contraction" concepts in the conceptual understanding of students. A quasi-experimental method has been used in the study. The sample group of the study consists of 5th grade students selected…

In line with previous studies, where outdoor nature experience was shown to support adolescents' environmental knowledge, our study monitored the influence of a hands-on environmental programme within a National Park on cognitive knowledge achievement.

The aim of this research is to investigate the effect of enriched learning environments which have been developed in the framework of the "erosion and landslide" concepts on the conceptual understanding of students. A quasi-experimental method has been used in this research. The sample consists of 40 students. 5th grade students (aged…

The aim of this study was to examine the effect of progressive sentence development activities on 5th graders' description skills. The study was conducted based on the pretest-posttest quasi-experimental model with a control group. A total of 58 students participated in the study; 29 in the control group, and 29 in the experimental group. The…

Students in U.S. public schools have consistently recorded substandard scores on measures of school performance in mathematics. This substandard performance could adversely affect the nation's future economic competitiveness, growth, and welfare. Educational and political leaders have sought school reforms that will result in U.S. students scoring…

This study was undertaken as an attempt to assess the effects of storytelling and reading aloud on fourth and fifth grade children's comprehension and oral reading fluency of both narrative and expository texts.
