The aim of this study was to investigate the effects of mathematics instruction supported by dynamics geometry activities on students’ achievement in area of quadrilaterals and students’ achievements according to their van Hiele geometric thinking levels. The study was conducted in a public elementary school in KırĢehir in 2012 – 2013 spring semester and lasted two weeks. The participants in the study were 76 seventh grade students. The study was examined through nonrandomized control group pretest-posttest research design. In order to gather data, Readiness Test for Area and Perimeter Concepts (RTAP), Area of Quadrilaterals Achievement Test (AQAT) and van Hiele Geometric Thinking Level Test (VHLT) were used. A twoway analysis of variance (ANOVA) procedure was employed to answer research questions. The result of the study indicated that there was a significant interaction between the effects of method of teaching and van Hiele geometric thinking level on scores of AQAT. In addition, mathematics instruction supported by dynamic geometry activities had significant effects on seventh grade students’ achievement on area of quadrilaterals topic. The results also revealed that students in experimental group were significantly more successful in AQAT than students in comparison group when the students were in second level of van Hiele geometric thinking.

Tükenmişlik duygusuyla baş edemeyen öğretmenler hem fiziksel hem de zihinsel olarak yorgun hissetmektedir. Bu duygunun üstesinden gelemeyen öğretmenler derslerini gerektiği şekilde yapamamaktadır. Bu yüzden araştırmada tükenmişlik yaşayan matematik öğretmenlerine nasıl müdahale edilmeli sorusu araştırılmıştır. Araştırma kapsamında katılımcılara, mesleğe başladıklarında danışanlarının matematik kaygısıyla baş etmeleri için ne tür çalışmalar yapacakları sorulmuştur. Araştırma sonucunda RPD adayları, tükenmişlik yaşayan matematik öğretmenine müdahale de bulunmadan önce öğretmenlik mesleği, çevresindeki kişiler ve kişisel sebeplerle ilgili bilgi toplamaya ilişkin önerilerde bulunmuşlardır. Rehberlik ve Psikolojik Danışman adaylarının tükenmişlik yaşayan matematik öğretmenine müdahale önerileri incelendiğinde bunların üç başlık altında toplandığı görülmektedir. Bunlar, kurama dayalı psikolojik danışmanlık yapmak, öğretmenlik mesleği ile ilgili durumlar hakkında ve çevresindekilere/çevresindekilerle işbirliği içinde yapılabilecek müdahale önerileri şeklinde isimlendirilmiştir.

In this study, the expectations of middle school students' parents regarding to "conceptual understanding and active student participation" "positive attitude and behavior attitude" and "authority and rule-oriented teaching" were examined. A valid and reliable threefactor instrument developed by the Aytekin, Baltaci, Altunkaya, Kiymaz and Yildiz (2016) was used in collecting parents' expectations. 749 parents participated in the study. It was found that the variables of parental gender, parental age range, and monthly income of the parents, level of loving mathematics and level of helping the child have no significant effect on the expectations. The university graduates had less authority and rule-oriented teaching expectation than the remaining parents. Besides, it is seen that the 5th grade parents had higher expectations of conceptual understanding and active participation and positive attitude and behavior than the other parents. It was determined that parents with very good past math achievement had higher expectations for "conceptual understanding and active participation" and "positive attitude and behavior". On the other hand, it is clear that the mathematical success perceived by the child's parents will have an effect on the behavior of the parents. A student who believes in learning mathematics through passive listening and memorizing rules can be more easily directed, if parent has a high expectation of active participation and conceptual learning. For that reason, educators should give importance to the family dimension that occurs outside the classroom.

It has been determined that the drawings, photographs and pictures related to the subject of the continuity of the tangent function on page 68 of the Ministry of National Education's twelfth-grade mathematics textbook contradict principles 1, 7 and 10 of Yanpar's (2007) teaching material development principles. According to these principles, teaching materials should: i) be simple, plain, and understandable, ii) reflect real life as much as possible, and iii) be easy to develop or revise, if necessary. This study aims to develop a portable tangent bridge model to meet the needs of the subject of the continuity of the tangent function. With this aim: i) teaching with the analogies model in the design of the teaching material, ii) "this is my project" format in the development and iii) Yanpar's (2007) principles were considered. The design of the model lasted 14 weeks. At the end of the study, a portable tangent bridge model from waste products was designed and developed. This model is thought to contribute to the teaching effectiveness of teachers (Shulman, 1987) with content knowledge alongside with pedagogical knowledge (Shulman, 1986). With this contribution, the needs of the subject as described by Taba (1962) and Tyler (1949) will be met. This model will also serve as an example of meeting the needs of the subjects of knowledge and its product, technology, as highlighted by Cahit Arf (Terzioğlu &Yılmaz, 2006).

The aim of this study is to reveal the suggestions of guidance and psychological counseling candidates (GPC) in dealing with math anxiety. The study analysed 50 GPC candidates' opinions and suggestions on math anxiety. The research study utilized case study method. The participants were asked to respond what kind of studies they would suggest to their clienst in order to overcome math anxiety once they begin to work in their profession. The interviews transcripts were converted into written documents. Content analysis was made on those documents to find GPC candidates' suggestions and opinions. Based on the findings, it can be concluded that the reasons of math anxiety can vary from individual to individual. Therefore, it was emphasized that the studies to determine the causes of math anxiety should be specific for each individual. Then, consultancy service should be formed based on the assessment of reasons that cause anxiety for each person. If the individual's math anxiety is caused by environmental factors such as teachers, families and peers, guidance and psychological counseling services should be offered to these environmental factors.

The aim of this research was to examine the anxieties and attitudes of elementary school students towards mathematics in terms of various variables. For this purpose, mathematics attitude scale and mathematics lesson anxiety scale were conducted to total of 437 students selected from the 4th and 7th grade in Şanlıurfa in the spring semester of 2010-2011 academic year. As a result, primary school students' anxieties toward mathematics do not differ according to gender, parents' occupation, parents' education status, monthly income level and taking or not extra support course. Besides, students' anxieties toward mathematics differ according to variables of class level, number of siblings, math scores and the person who encourage them to love mathematics. The attitudes of primary school students towards mathematics do not differ according to the variables of gender, mother 's and father' s profession, parents' education status, family monthly income level, number of siblings and math scores of students. But the attitudes of primary school students towards mathematics do differ according to the variables of taking or not extra support course, class level, and the person who encourage them to love mathematics. In this research, a positive low level of relationship between anxiety and attitude towards mathematics were found.

Günümüzde organizasyonlar başarıyı yakalamak ve rekabet avantajı sağlayabilmek için çalışan memnuniyeti ve kaliteye önem vermektedir. Çalışan memnuniyetinin olması örgütsel performansın artmasına ve örgütün gelişimine neden olmaktadır. Özellikle çok sayıda rakibin olduğu sektörlerde sürdürülebilir rekabet avantajı yakalamanın bir yoluda çalışanların problemlerini çözüp onlara ilişkin iyileştirme çalışmaları yapmaktır. Bu hem organizasyon başarısı hemde kaliteyi yakalamak açısından önem arzeder. Bu çalışmada bir kalite göstergesi olarak çalışan memnuniyeti ölçeği geliştirilmeye çalışılmıştır. Çalışmaya 2016-2017 eğitim-öğretim yılı bahar dönemde Ahi Evran Üniversitesi’nde görev yapan 342 akademik ve 244 idari personelinden toplam 586 çalışan katılmıştır. Ölçek maddelerinin yazımına başlanmadan araştırmacılar tarafından literatür taraması yapılarak diğer memnuniyet ölçekleri incelenmiştir. Ölçek geliştirme amacıyla yapılan çalışmada açımlayıcı ve doğrulayıcı faktör analizleri yapılmış...
