Origami, known as paper folding art, is used in mathematics education as a teaching tool. The fact that using origami in mathematics lessons makes teaching mathematical concepts easier and makes lessons enjoyable is taken into account, there is as need to improve prospective elementary mathematics teachers’ skills of using origami. In this context, in this study, prospective elementary mathematics teachers’ use of origami with elementary mathematics curriculum was investigated. In this qualitative study which is conducted in the light of non-positivist interpretive paradigm, research design was determined as a case study. 64 prospective elementary mathematics teachers who took Origami with Mathematics elective course and still study in faculty of education at one of the universities which is located in northeast of Marmara region constitute the sample of the study. Data collection tools were diaries collected from prospective teachers on a weekly basis, micro teaching presentations made by prospective teachers and micro teaching folders prepared by prospective teachers. In data analysis process, firstly topics associated to origami models in lessons and then, topics chosen for micro teaching presentations by prospective teachers were analyzed by using descriptive statistics. In diaries, it was seen that most related models to mathematics topics and objectives selected by prospective teachers in curriculum were models which are easy to be made such as pine tree and lily. It was observed that prospective teachers associated origami to seventh grade topics most and these topics generally include geometric concepts. In addition, fractions, ratio-proportion, rational numbers and first degree equations were also selected by prospective teachers. According to the results of the study, at the end of the implementation process, it can be said that prospective teachers’ hand skills developed and their skills of connecting origami to elementary mathematics curriculum improved through origami. Furthermore, they realized that origami can be used in mathematics lessons a teaching tool. Extended English abstract is in the end of Full Text PDF (TURKISH) file. ÖzetKağıt katlama sanatı olarak bilinen origami, matematik eğitimi alanında bir öğretim aracı olarak kullanılmaktadır. Matematik derslerinde origami kullanımının, matematik kavramlarının aktarılmasını kolaylaştırdığı, öğretim sürecini eğlenceli hale getirdiği göz önüne alındığında matematik öğretmen adaylarının origamiyi kullanma becerilerinin geliştirilmesi gerekliliği hissedilmektedir. Bu bağlamda bu araştırmada ilköğretim matematik öğretmen adaylarının ortaokul matematik öğretim programında origami kullanımları incelenmiştir. Pozitivist olmayan yorumlayıcı paradigmanın izlerini taşıyan nitel araştırmada, durum çalışması araştırmanın deseni olarak benimsenmiştir. Araştırmanın çalışma grubunu Marmara bölgesinin kuzeydoğusunda yer alan bir üniversitenin eğitim fakültesinde öğrenim gören ve Origami ile Matematik seçmeli dersini alan 64 ilköğretim matematik öğretmen adayı oluşturmaktadır. Veri toplama araçları olarak öğretmen adaylarına rutin olarak her hafta dağıtılan günlükler, öğretmen adaylarının yapmış oldukları mikro öğretim sunumları ve dosyaları kullanılmıştır. Veri analiz sürecinde, öncelikle ders içerisinde görülen origami modelleri ile ilişkilendirilen konuların, sonrasında ise mikro öğretim sunumları için seçilen konuların betimsel istatistikler ile analiz edilmiştir. Öğrenci günlüklerinde çam ağacı, zambak gibi yapımı kolay olarak nitelendirilebilecek modellerin öğretmen adayları tarafından öğretim programındaki kazanım ve konularla daha fazla ilişkilendirilmiştir. Origami ile yedinci sınıf konularının ağırlıkla ilişkilendirildiği ve bu konuların genellikle geometrik kavramları içeren konular olduğu gözlemlenmiştir. Ayrıca kesirler, oran-orantı, rasyonel sayılar ve birinci dereceden denklemler gibi konularında öğretmen adayları tarafından seçildiği belirlenmiştir. Araştırma sonucunda öğretmen adaylarının origami kullanabilmek için el becerilerinin ve ortaokul matematik öğretim programı ile ilişkilendirme becerilerinin geliştiği, origamiyi matematik derslerinde kullanılabilecek bir öğretim aracı olarak görmeye başladıkları sonucuna ulaşılmıştır

Secondary School Students’Attitudes towards the Concept of Equality and Preservice Teachers’ Professional Noticing

With the understanding of importance of pedagogical content knowledge, professional noticing has become one of the research subjects of the mathematics educators for the last 10 years. This qualitative study which explores secondary school students’ solution processes regarding the concept of equation ,one of the main components of algebraic learning field and the pre-service teachers’ noticing about this is quite rich in terms of its results. The 6th, 7th, and 8th graders’ attitudes towards equations were revealed and it was found as stated in literature that students were dominantly “computational thinkers”. However, the differences in this general concept of thinking seem to make contribution to literature by involving discrete attitudes. In addition to this, the secondary findings of the study include some evidence revealing that pre-service teachers’ level of noticing accumulates at middle levels but they can be improved

Psychometric properties of sleep quality scale and sleep variables questionnaire in Turkish student sample

Sleep is a physiological need that affects physical and mental performances. However, the number of individuals who experience problems related directly or indirectly with sleep is increasing in many countries. Therefore, it is important to have a short, reliable and valid measure to assess both sleep quality and sleep related variables in school-age children. This study aims to carry out the validity and reliability studies for the Sleep Quality Scale and Sleep Variables Questionnaire (SQS-SVQ) used to determine sleep quality, parental control, total sleep time, mid-point of sleep and sleep efficiency and to adapt it into Turkish. The SQS-SVQ consists of seven scale items to measure sleep quality and eight questionnaire items. The validity and reliability studies of the instrument were carried out on data acquired from 4th-8th graders. Factorial validity for SQS and criterion related validity analyses were carried out for the validity of the SQS-SVQ and correlations ranged from 0.51 to 0.73. These analysis results put forth that the scale is a valid measurement tool. Internal consistency coefficient of the SQS was 0.72 and test-retest correlations of the SQS-SVQ ranged from 0.67 to 0.88. These acquired results indicated that the scale is reliable. Meanwhile, gender measurement invariance was tested for SQS and results indicated that gender measurement invariance was established. These results have shown that the SQS-SVQ can be used in social researches and especially in educational studies

The Relationship between 8th Grade Students’ Opinions about Problem Solving, Beliefs about Mathematics, Learned Hopelessness and Academics Success

Related literature emphasizes that affective factors are impactful on cognitive factors. For this reason, this study aims at revealing the relationship between problem solving,  which is one of metacognitive characteristics, beliefs about mathematics and learned hopelessness, which are two affective characteristics. Therefore, addressing emotional aspects together with cognitive abilities will give rise to understanding of the students’ current situation and predicting about in which fields they will be able to succeed in math in the future.  The study is a descriptive research designed as a relational survey method. The sample of the study was  comprised  of 518  students of 8th  grade. The  data  collection  instruments  conducted  in  the  study were the  Problem Solving Scale, Learned Helplessness in Mathematics Scale and Mathematics  Belief  Scale. The findings showed that there was a positive relationship between problem solving and math beliefs; a negative relationship between beliefs about mathematics and learned helplessness; problem solving and learned helplessness

How will employees who get away from society because of factors such as increasing work intensity with globalization, rapid consumption by impact of capitalism, mechanized organizational structure due to technological development and momentary satisfaction through easy access to information, ensure that organizations maintain their existence, protect their level of competitive and make profits on the average? In this context, the aim of the present study was to investigate the effects of spiritual leadership on employee empowerment and work procrastination in organizations. A questionnaire was applied face-to-face to the employees of the private sports-fitness center operating in Sakarya by using judicial sampling method within the scope of the study. As a result of the analysis of the obtained data; it was determined that there was low and positive relationship between "meaning/call" which was the sub-dimension of spiritual leadership, discretion and responsiveness which was the sub dimensions of empowerment. Adoption of work by employee, sense of belonging to work and meaning of the work can produce solutions without the approval of the managers and meet the requests and needs. A negative relationship was determined between altruistic love which was the sub dimension of spiritual leadership and work procrastination. The managers who are honest, consistent, courteous and look after employees' rights provide them not to delay their works. One of the important findings of the research is that individuals who have the control in their works will develop their self-confidence however they could delay their work
