This study aimed to determine the effects of drama based learning on seventh grade students&rsquo / achievement (angles and polygons, circle and cylinder), attitudes and thinking levels in geometry compared to the cooperative learning. The study was conducted on four seventh grade classes from two public elementary schools in the same district in the 2006-2007 academic year, lasting seven and a half week (30 lesson hours). The data were collected through angles and polygons (APA) / and circle and cylinder achievement (CCA) tests, the van Hiele geometric thinking level test (POSTVHL), geometry attitude scale (PRE-POSTGAS). The quantitative analyses were carried out by using Multivariate Analysis of Variance (MANOVA). The results showed that drama based learning had a significant effect on students&rsquo / angles and polygons achievement, circle and cylinder achievement, van Hiele geometric thinking level compared to the cooperative learning. However, attitude findings regarding the attitudes revealed that there is not a significant difference according to the geometry attitudes of drama group and cooperative group after treatment. Both the two instructional methods supported active participation, created cooperative working environment, included daily life examples and gave the chance to classroom communication. On the other hand, drama group students&rsquo / significantly better performance was attributable to the make belief plays and improvisations of daily life examples included in drama activities.

This study aimed to investigate the effects of using dynamic geometry software while teaching by guided discovery compared to paper-and-pencil based guided discovery and traditional teaching method on sixth grade students&rsquo / van Hiele geometric thinking levels and geometry achievement. The study was conducted in one of the private schools in Ankara and lasted six weeks. The sample of the study consisted 47 sixth grade students in the school. The present study was designed as pretest-posttest control group quasi-experimental study.In order to gather data, Geometry Achievement Test (GAT) and Van Hiele Geometric Thinking Level Test (VHL) were used. At the end of the research, the data were analyzed by means of analysis of covariance. The results of the study indicated that there was a significant effect of methods of teaching on means of the collective dependent variables of the sixth grade students&rsquo / scores on the POSTVHL after controlling their PREVHL scores, and there was a significant effect of methods of teaching on means of the collective dependent variables of the sixth grade students&rsquo / scores on the POSTGAT after controlling their PREGAT scores.

The aims of this study were to investigate the effects of drama based instruction on seventh grade students&rsquo / achievement on geometry (angles and polygons / circle and cylinder), retention of achievement, van Hiele geometric thinking level, attitudes toward mathematics and attitudes toward geometry compared to the traditional teaching / to get the students&rsquo / views related to the effects of drama based instruction on their learning, friendship relations, awareness of themselves, and the role of teacher and students / and to get the view of teacher who was present in the classroom during the treatment on drama based instruction. The study was conducted on three seventh grade classes from a public school in the 2002-2003 academic year, lasting 30 lesson hours (seven and a half week). v The data were collected through angles and polygons / and circle and cylinder achievement tests, the van Hiele geometric thinking level test, mathematics and geometry attitude scale, and interviews. The quantitative analyses were carried out by using two multivariate covariance analyses. The results revealed that drama based instruction had a significant effect on students&rsquo / angles and polygons achievement, circle and cylinder achievement, retention of these achievement, van Hiele geometric thinking level, mathematics attitude, and geometry attitude compared to the traditional teaching. According to the interview responses of the experimental group students and the classroom teacher, significantly better performance of the experimental group students was attributable to the potential of the drama based instruction to make learning easy and understanding better by / supporting active involvement, creating collaborative studying environment, giving chance to improvise daily life examples, giving opportunity to communicate, providing meaningful learning, supporting long-lasting learning and providing selfawareness.

For the purpose of this study, the geometric images refer to the results obtained by reproducing the percept of elements that constitute the content of geometry. The scientific problem addressed in this study is the achievement of more effective geometric images formation at primary school stages on the basis of holistic approach to the geometric education. The study objective is to get deeper knowledge of the mechanism on the formation of geometric images at primary school. The theoretical analysis includes the definition of geometric image conception worked out based on the works of scientists representing a variety of different disciplines, the overview of the existing situation with respect to the formation of geometric images in pupils of primary school and modelling of geometric images formation process at primary school stage based on the results of theoretical analysis. The experimental study on the development of geometric images at primary school stages was planned based on the hypothetical geometric images formation model. The study has been narrowed down to the evaluation of the impact that the manual constructive geometry has upon the geometric images of schoolchildren. The empirical reasoning of dissertation, in total: questionnaire data completed by 653 schoolchildren and qualitative data collected in the result of formative experiment. The results of the study may be applied in the process of training future teachers of primary school. They may also be... [to full text]
