The general aim of this study was to investigate sixth and seventh-grade students’ strategies in solving proportional problems supported with interactive simulations. In this respect, the first aim was to investigate how sixth and seventh-grade students classify proportional problems. The second aim was to examine the strategies that sixth and seventh-grade students employ while solving proportional problems supported with interactive simulations and determine which levels these strategies correspond to on The Ongoing Assessment Project (OGAP) Ratio and Proportion Progression (Petit et al., 2020). The third purpose was to investigate the role of the numerical structure of the problems (i.e., integer ratio, non-integer ratio, letters) on students’ selection of strategies in solving problems supported with interactive simulations. The data were collected from seven sixth graders and seven seventh graders during the June-July period of 2021. Interviews were held online via the Zoom platform. Each interview was recorded and transcribed for analysis. Findings revealed that sixth and seventh-grade pupils classify proportional problems based on problems’ contextual aspects, problems’ nature, and the words that sounded reminiscent of each other. In addition, one seventh-grade student focused on the interrogative word of the question in the problem. Moreover, among all the strategies proposed in The OGAP Ratio and Proportion Framework, only three of them were observed among students’ answers, either as a single strategy or multiple strategies. Non-proportional strategies were primarily used in the non-integer ratio numerical structure. Early ratio strategy was employed only on the first question, and lastly, the use of proportional strategies was seen almost in each question. When the multiple strategies of the students were examined, it was found that all the multiple strategies started from a lower level and moved to a higher level. In addition, among all question types, the use of multiple strategies was not observed only in problems involving letters.

Middle school students' proportional reasoning in real life contexts in the domain of geometry and measurement Ayan Civak, Rukiye; IŞIKSAL BOSTAN, MİNE (2019-01-01) The purpose of this study was to examine middle school students' proportional reasoning, solution strategies and difficulties in real life contexts in the domain of geometry and measurement. The underlying reasons of the difficulties were investigated as well. Mixed research design was adopted for the aims of the study by collecting data through an achievement test from 935 sixth, seventh and eighth grade students. The achievement test included real life problems that required proportional reasoning, and we...
Sixth, seventh and eighth grade teachers' conception of assessment Vardar, Emine; Aksu, Meral; Department of Educational Sciences (2010) The main purpose of this study was to investigate sixth, seventh, and eight gradeTurkish, English, Mathematics, Science and Technology, and Social Studies teachers’ conceptions of assessment. It was also aimed at finding out the differences, if any, in teachers’ conceptions of assessment according to their teaching subject, years of teaching experience, in-service training, and the undergraduate institution they graduated from. There were 414 teachers included in the study. Data were gathered through the sh...
Investigating middle school students’ achievement and strategies in proportional reasoning problems Yılmaz, Gamze Öze; Akyüz, Didem; Department of Elementary Science and Mathematics Education (2019) The aims of the study are to specify the academic achievement of the fifth, sixth, seventh and eighth grade students in proportional reasoning problems, to determine how the academic achievement of these students change according to problem types, to examine their solution strategies in these problems, and to reveal how these strategies diversify from fifth to eighth grade. To collect data in order to achieve these aims, a proportional reasoning test were prepared. The study was designed as a mixed study. I...
Pre-service teachers' achievement and perceptions of the classroom environment in flipped learning and traditional instruction classes ÖZÜDOĞRU, MELİKE; Aksu, Meral (Australasian Society for Computers in Learning in Tertiary Education, 2020-01-01) The aim of this study was to investigate whether flipped learning affects pre-service teachers' achievement and perceptions related to the classroom environment. This experimental study was conducted in the fall semester of 2017-2018 for 11 weeks at a state university in Turkey and included a total of 56 pre-service teachers. An achievement test and a scale were implemented to collect the data. The analyses through descriptive and inferential statistical analysis techniques showed that flipped learning grou...
Seventh Graders' Statistical Literacy: an Investigation on Bar and Line Graphs Çatman Aksoy, Emine; Işıksal Bostan, Mine (2020-02-10) The aim of the current study was to investigate the statistical literacy of seventh grade students regarding the concepts of average and variation on bar and line graphs presented in alternative real-life contexts. To this end, the statistical literacy levels of the seventh grade students were initially determined. Subsequently, definitions, interpretations and evaluations generated by the students at varying levels of statistical literacy were examined in further depth. More specifically, a qualitative sur...
