Öz Anahtar SözcüklerBu araştırmada; Matematik Dersi Öğretim Programı yer alan veri işleme ve olasılık öğrenme alanlarına yönelik alan yazında yer alan araştırma eğilimlerini incelemek amaçlanmıştır. Bu amaçla Türkiye'de yapılan ortaokul düzeyinde 34 bilimsel makale, 24 yüksek lisans ve 3 doktora tezi olmak üzere toplam 61 çalışma taranıp içerik analizi yapılmıştır. İlgili çalışmalara ulaşabilmek için; olasılık, veri işleme, grafik kavramları ile istatistiksel düşünme ve istatistiksel okuryazarlık kavramları çerçevesinde tarama yapılmıştır. Araştırmanın bulguları anahtar kelimeler, araştırma yöntemleri, araştırma desenleri, örneklem büyüklüğü, veri toplama araçları, veri analiz yöntemleri ve araştırmaların amaç ve sonuçlarını kapsayacak şekilde temalara ayrılmıştır. Veriler, yüzde ve frekansa dayalı olarak yorumlanmış, bulgular tablolarla sunulmuştur. Elde edilen bulgulara dayanarak, yapılan araştırmaların çoğunluğunun Veri ve Olasılık öğrenme alanlarında kullanılabilecek öğretim yöntemlerinin etkililiğini araştırmak amacıyla yapıldığı; yöntem olarak çoğunlukla nicel araştırma yöntemlerinin, desen olarak ise deneysel desenlerin kullanıldığı; verilerin ise en çok başarı testleri aracılığıyla elde edildiği tespit edilmiştir. Araştırmaların sonuçları incelendiğinde en çok işbirlikli öğrenme yönteminin etkili olduğu, yaşanılan zorluklar incelendiğinde ise en çok çizgi grafiği konusunda zorlanıldığı sonucu elde edilmiştir. Abstract KeywordsThis study aims to investigate research trends in the literature on Data Processing and Probability learning areas in the Mathematics Curriculum. To this end, a total of 61 studies performed at elementary school level (5-8th grades) in Turkey, including 34 papers, 24 theses and 3 dissertations were reviewed and subjected to content analysis. To reach relevant studies, the literature was reviewed within the concepts of probability, data processing, graphics and statistical thinking/literacy. The findings were categorized into themes including keywords, methods, designs, sample sizes, instruments, data analysis methods and objectives and results of the research. The data was interpreted based on percentage and frequency, and the findings were presented in tables. Based on the findings obtained, it was determined that most of the studies have been performed to examine the effectiveness of teaching methods suitable of being used in Data and Probability. It was also found that the most commonly used methods are quantitative methods and the most commonly used designs are experimental designs, and that the data have been obtained mostly through achievement tests. When the results of the studies have been examined, it was concluded that the most effective learning method is cooperative learning, and that the biggest challenge is related to line chart.

This study aims to determine the misconceptions and difficulties of sixth-grade students on the subject of angles. The study participants are 25 sixth grade students from a public school in a city in western Turkey during the 2017-2018 academic year. This qualitative study used 17 open-ended questions designed by the researchers for data collection to examine the students' misconceptions and difficulties. Data were examined by implementing content analysis. It has been analysed that students cannot define the angle due to difficulties and misconceptions in determining the corners and edges of a symbol. Besides, they also find it difficult to compare the measures of the angles, adjacent angles, complementary and supplementary angles.

The purpose of this research was to analyze the process of teaching mathematics through the flipped classroom model based on preservice teacher opinions. The study group consisted of 16 preservice teachers from a primary school teaching program at a state university in Turkey who agreed to participate voluntarily. The research was designed as a practical action research study. After the five-week implementation period, two separate focus group discussions occurred with the volunteer preservice teachers. Consequently, in addition to the positive contribution to learner responsibility made by the flipped classroom, it was also observed that the in-class teamwork processes contributed to make the mathematics course entertaining. Moreover, peer learning was implemented, and the sense of belonging made a positive contribution to academic achievement in a teamwork process. In addition, preservice teachers started to see the academician as a role model at the end of the implementation process; this was a valuable result in terms of pedagogical contribution. Further research, gamification are used or environments enriched with virtual reality applications can be performed.

As a result of the COVID-19 pandemic, distance education started at K-12 levels in the spring semester of the 2019-2020 school year. The Ministry of National Education had also published instructional tasks to be used in distance education at all grade levels in order to create mathematics learning opportunities for students and to provide resources for teachers. Well-structured and high-quality instructional tasks play an important role in students' learning mathematics. The aim of this study is to examine the quality of the elementary school mathematics tasks recommended for distance remedial education from multiple perspectives, in particular their cognitive demand levels. A total of 85 tasks focusing on 79 critical objectives in grades 1-4 mathematics were examined using document analysis. Results of this study showed that the majority of the tasks were at low cognitive demand level, cognitive demand levels did not show a balanced distribution, and some tasks had mathematical errors.
