The purpose of the study was to investigate the effects of real data based and calculator supported statistics activities on 7th grade students’ statistics performance and attitudes towards statistics when the statistics performance of the students prior to the instruction and the previous mathematics grades were controlled. A quasi-experimental design was used to investigate the research problem. The research was conducted by 84 seventh grade students. There were three groups in the study. Two of them were experimental groups and one of them was control group. The first group received instruction by the traditional method (TM), the second group received instruction by real data based and calculator supported statistical activities (RDBCSSA), and the third group was instructed by real data based statistical activities (RDBSA), the number of the subjects was 28, 27 and 29 respectively. Data were collected through three different measuring instruments: 1.Statistical Performance Test 1 (SPT1); 2.Statistical Performance Test 2 (SPT2); 3.Statistics Attitude Scale (SAS). The SPT1 was used as a pre-test. The SPT2 was administered as a post-test. SPT1 and SPT2 were used to determine the statistics performance of the students before and after the instruction. SAS was used to determine the attitudes of the students toward statistics. The data of this study were analyzed by analysis of variance (ANOVA) and analysis of covariance (ANCOVA). The results revealed that there was no significant mean difference among the groups with respect to statistics performance. Also there was no significant mean difference among the groups with respect to attitudes towards statistics. The mean scores of the Statistics Attitude Scale items were calculated and the results revealed that the students had positive attitudes to the statements in Statistics Attitude Subscale 1 (Confidence in Learning Statistics) and they were neutral to the statements of the Statistics Attitude Subscale 2. Also the students wrote their opinions about the teaching methods and their impressions were analyzed by making a frequency table. Most of the TM students mentioned that the examples should be more attractive such that the activity sheets could contain real data based examples. However some of the students mentioned that traditional method was good and the subject was understood very well. Most of the RDBSA students mentioned that the teaching method was enjoyable. Most of the RDBCSSA students expressed that the calculators made the lessons enjoyable and the study easy.

An investigation of mathematics achievement of eighth grade students with respect to their learning styles
Kurbal, Serkan Süleyman; Çakıroğlu, Erdinç; Department of Educational Sciences (2011)
This study aimed to investigate the differences in mathematics achievement scores of the eighth grade students with respect to their learning styles. Mathematics achievements of the eighth grade students were determined by the number of correct answers given in the mathematics subtest of Level Determination Examination (abbreviated in Turkish as SBS) which was administered in June 2009. Mathematics achievements of the eighth grade students were also determined by teacher-assigned mathematics grades which we...
An analysis of teacher background indices and their relation to the eighth grade Turkish students’ mathematics achievement in TIMSS 2007
Mihyap, Kübra; Berberoğlu, Halil Giray; Department of Secondary Science and Mathematics Education (2011)
The purpose of this study is to investigate teacher background indices and their relation to mathematics achievement. For this purpose, the data collected from 146 Turkish mathematics teachers and 4498 8th grade Turkish students with the instruments - mathematics teacher background questionnaire and mathematics achievement test in the Trends in International Mathematics and Science Study (TIMSS 2007) were analyzed by using the Pearson’s Product Moment Correlation. The teacher background indices, constructed...
7th-grade students’ typical errors and possible misconceptions in graphs concept before and after the regular mathematics instruction
Tortop, Tuğba; Haser, Çiğdem; Department of Elementary Science and Mathematics Education (2011)
The purpose of this study was to investigate 7th-grade students’ typical errors and possible misconceptions in graphs concept before and after the regular mathematics instruction. The study was conducted in an elementary school in the 2nd semester of 2009-2010 academic year in Afyonkarahisar. A mathematics teacher and 71 7th-grade students participated in the study. The data were collected through achievement tests administered to the students before and after the instruction and interviews conducted with t...
The Development of Children s Algebraic Thinking The Impact of a Comprehensive Early Algebra Intervention in Third Grade
Blanton, Maria; Stephens, Ana; Knuth, Eric; Gardiner, Angela; İşler Baykal, Işıl; Kim, JeeSeon (National Council of Teachers of Mathematics, 2015-01-01)
This article reports results from a study investigating the impact of a sustained, comprehensive early algebra intervention in third grade. Participants included 106 students; 39 received the early algebra intervention, and 67 received their district's regularly planned mathematics instruction. We share and discuss students' responses to a written pre- and post-assessment that addressed their understanding of several big ideas in the area of early algebra, including mathematical equivalence and equations, g...
An Investigation of 7th grade students’ statistical literacy about the concepts of average and variation on bar and line graphs
Çatman Aksoy, Emine; Işıksal Bostan, Mine; Department of Elementary Science and Mathematics Education (2018)
The aim of the present study was to analyze statistical literacy of seventh grade students on the concepts of “average” and “variation” on bar and line graphs related to the data obtained from social or scientific contexts. More specifically, seventh grade students’ statistical literacy levels in terms of the concepts of “average” and “variation” on bar and line graphs related to the data obtained from social or scientific contexts were determined and how students at different statistical literacy levels de...
