Abstract/Notes: This article reflects how to know about Montessori pedagogy and the process she followed to build it, can help future teachers to be reflective and innovative. The aim is not to suggest that student teachers should know the pedagogy of Montessori, nor that of any specific pedagogue, and to put it into practice or imitate it, without further ado. Educational literature agrees that an educational system will be as good as its teachers, and they will not be able to improve education if they simply apply methods designed by others in an uncritical and decontextualized way. After describing how Montessori came to propose her method and establish her pedagogical principles, the importance of linking theory and practice in the initial and permanent training of future teachers is underlined.

American Writings on Maria Montessori: An Inquiry into Changes in the Reception and Interpretations Given to Writings on Maria Montessori and Montessori Educational Ideas 1910-1915 and 1958-1970

Abstract/Notes: The purpose of this dissertation will be to survey and analyze American writings on Maria Montessori and her educational system, in order to show how the idea of Montessori education has interacted with some changing American ideas and social forces. These changes in social and intellectual currents can be likened to a shift from centrifugal to centripetal force; or to the expansion and then the contraction of a universe. The central metaphor is the same. It is applicable to, and illustrative of, much about the changing social and educational scene in America. The writings on Montessori, examined against this framework, should provide a new view on certain changes in American educational thinking.

Abstract/Notes: Ausgehend von der Beobachtung, dass in der Unterrichtsforschung Konzepte des „offenen Lernens“ für die Implementierung neuer Medien, wie dem Internet, empfohlen werden, wird der Zusammenhang zwischen reformpädagogischen Ansätzen und neuen Informationstechnologien hergestellt. Hier knüpfen die Untersuchungen der vorliegenden Arbeit an. Herausgegriffen wird das Konzept Maria Montessoris, untersucht in den USA, wo sich zum einen alternative Pädagogiken freier entwickeln können und zum anderen die Implementierung neuer Medien in den Unterricht offensiver vorangetrieben wird. Es wird angenommen, dass die Lernumgebung Montessoris unter dem Gesichtspunkt einer Modernisierung des Konzepts auf die heutigen Ansprüche eine optimale Lernlandschaft bietet, das Internet als natürliche Informationsquelle in den Unterricht zu integrieren. Die gegenwärtig kontroverse Umsetzung der Pädagogik Montessoris (AMI und AMS) sowie die zu diesem Zeitpunkt verwirklichte Internetnutzung in den Schulen werden am Beispiel der USA einer kritischen Reflexion unterzogen. Kapitel 1 dieser Arbeit betrachtet die Pädagogik Montessoris. Ein Abschnitt liefert Informationen über die kontemporäre Verwirklichung ihrer Pädagogik in den USA. Die Möglichkeiten des Internets für den Unterricht, die Aussagen der Forschung über das informationstechnische Lernen sowie seine Integration in den USA, wird in Kapitel 2 näher untersucht. In Kapitel 3 wird die Notwendigkeit des Interneteinsatzes in Schulen überprüft und die Eignung offener Strukturen als Basis dafür begründet. Die gewonnenen Erkenntnisse geben die Grundlage zu den in Kapitel 4 und 5 beschriebenen Untersuchungen, wie diese Implementierung in der Praxis nordamerikanischer Montessori-Schulen verwirklicht ist. Beschrieben wird sowohl eine Querschnittsuntersuchung als auch eine Fallstudie. Kapitel 6 schildert die pädagogischen Konsequenzen für die Nutzung des Internets im Unterricht. [Based on the observation that teaching research recommends concepts of “open learning” for the implementation of new media such as the Internet, the connection between reform-pedagogical approaches and new information technologies is established. This is where the investigations of the present work tie in. The concept of Maria Montessori is being singled out, examined in the USA, where, on the one hand, alternative pedagogies can develop more freely and, on the other hand, the implementation of new media in the classroom is being promoted more aggressively. It is assumed that the Montessori learning environment, from the point of view of modernizing the concept to meet today's requirements, offers an optimal learning landscape to integrate the Internet as a natural source of information into the classroom. The currently controversial implementation of Montessori pedagogy (AMI and AMS) as well as the internet usage in schools at that time are subjected to critical reflection using the example of the USA. Chapter 1 of this thesis looks at Montessori's pedagogy. A section provides information on the contemporary realization of their pedagogy in the USA. The possibilities of the Internet for teaching, the statements of research about information technology learning and its integration in the USA are examined in more detail in Chapter 2. Chapter 3 examines the necessity of using the Internet in schools and explains the suitability of open structures as a basis for this. The knowledge gained provides the basis for the investigations described in Chapters 4 and 5, how this implementation is realized in practice in North American Montessori schools. Both a cross-sectional study and a case study are described. Chapter 6 describes the pedagogical consequences for the use of the Internet in the classroom.]

Abstract/Notes: The aim of this study is to analyze the peer play behaviors of preschool children according to views of their teachers and their parents by the type of school. The research sample consisted of parents of 36-72 months old children attending Private Montessori Preschools and Private Preschools in Çankaya, Ankara (N = 243) and teachers working in these schools (N = 46). Penn Interactive Peer Play Scale-Parent Form (PIPPS-P) and Penn Interactive Peer Play Scale-Teacher Form (PIPPS-T) that were developed by Fantuzzo, Mendez and Tighe (1998) and were made its adaptation to Turkish by Ahmetoğlu, Acar and Aral (2016, 2017), General Information Form "including sociodemographic characteristics of children and their parents and General Information Form which includes sociodemographic and professional characteristics of teachers were used. The study was designed in quantitative research approach and survey method was used. While analyzing the data, Independent Sample t Test, Paired t Test and descriptive statistical methods were used. In the result of the study; it is seen that the majority of the parents in both groups are between 36 and 40 years of age, they have a job and they work, have a nuclear family, and have one child. It is observed that teachers working in Montessori Private Schools are younger, have higher level education than the teachers working in Private Schools. It was found that all of the teachers allow outdoor time to children in daily routine in both groups. Outdoor time span varies from school to school at Montessori Private Preschools. Outdoor time span varies from school to school besides it varies from teacher to teacher in the same school at Private Preschools. It has seen in the research that Private preschools' teachers didn't take Montessori teacher training and Montessori preschool teacher's took Montessori teacher training. It was determined that the teachers working in the Montessori preschools took Montessori trainings from the school director that they are working for. Factor Analyses showed that there is no significant difference in the scores of "Play Disruption" and "Play Disconnection" factors of Penn Interactive Peer Play Scale-Parent Form (PIPPS-P) and Penn Interactive Peer Play Scale-Teacher Form (PIPPS-T) (p>0,05). There is significant difference in the third factor of both scales: "Play Disconnection" (p<0,05). Teacher scores are higher than parents' scores. In addition, the opinions of the teachers who participated in the research were compared with the opinions of parents. Factor analyes show that there is significant different in all areas (p<0,05). Teacher's scores are higher than parents' scores in tha factors of "Play Disruption" and "Play Disconnection". Parents' scores are higher than teachers' scores in factor of "Play Disconnection". Preschool is a period from three to six years. This age range is a period in which children play with their peers. As a result of playing with peers, positive play behaviors ("Play Interaction") such as sharing his/her toy with a friend, showing positive emotions during the play and negative play behaviors ("Play Disruption") such as usurping his/her friend toys, crying, showing agression are common play behaviors of preschool children. As a result of the study, both the teachers and parents' opinions show that the positive and negative play behaviors of children do not differ according to the type of school. In other words, there is no difference between the positive and negative play behaviors of preschool children who attend Montessori and who attend Non-Montessori schools. According to the result, we can say that wherever there is a child there is play and this situation does not differ according to the type of school. However, according to the type of school, the point that differs is about "Play Disconnection". The scores of the "Play Disconneciton" which includes play behaviors such as wandering outside the play group, refusing to participate in play are high in Montessori group. In other words, "Play Disconnection" behaviors are more common in children who are attending Montessori schools. The reason for the result can be explained by the principles of Montessori education. The principle of free choice and respect to the child. In Montessori schools, children are not forced for anything even play. Therefore, the child participates in the play whenever he/she wants. If he/she doesn't want to participate in the play it is okey for teachers so children are free walking in a classroom, outside the play group. / Bu çalışmada; Montessori eğitimi veren özel okul öncesi eğitim kurumlarına devam eden çocuklar ile MEB programı uygulayan özel okul öncesi eğitim kurumlarına devam eden çocukların oyun davranışlarının, anne-baba ve öğretmen görüşlerine göre incelenmesi amaçlanmıştır. Araştırmanın çalışma grubunu, Ankara ili Çankaya ilçesinde bulunan Montessori eğitimi veren özel okul öncesi eğitim kurumları ve MEB programı uygulayan özel okul öncesi eğitim kurumlarına devam eden 36-72 aylık çocukların anne-babaları (n=243) ve öğretmenleri (n=46) oluşturmaktadır. Çalışma grubundaki çocukların akran oyun davranışlarını incelemek amacıyla Fantuzzo, Mendez ve Tighe (1998) tarafından geliştirilen; Ahmetoğlu, Acar ve Aral (2016, 2017) tarafından Türkçeye uyarlaması yapılan "Penn Etkileşimli Akran Oyun Ölçeği Ebeveyn Formu (PEAOÖ-E)", "Penn Etkileşimli Akran Oyun Ölçeği Öğretmen Formu (PEAOÖ-Ö)", çocukların ve anne-babalarının sosyodemografik özelliklerini içeren "Anne-Baba Genel Bilgi Formu" ile öğretmenlerin sosyodemografik ve mesleki özelliklerini içeren "Öğretmen Genel Bilgi Formu" kullanılmıştır. Verilerin analizinde parametrik testlerden Bağımlı Örneklem t Tesi (Independent Samples t Test) ve Bağımsız Örneklem t Testi (Paired Samples t Test), tanımlayıcı istatistiksel metotlar (yüzde, ortalama, maksimum ve minumum değerler) kullanılmıştır. Araştırmada; her iki gruptaki anne-babalarının büyük çoğunluğunun 36-40 yaş aralığında olduğu, çalıştığı, çoğunluğunun çekirdek aileye ve tek çocuğa sahip olduğu görülmektedir. Montessori eğitimi uygulayan ÖOÖEK'da çalışan öğretmenlerin MEB programı uygulayan ÖOÖEK'ndaki öğretmenlere göre daha genç oldukları, lisans/lisansüstü mezuniyet oranının daha yüksek olduğu görülmektedir. Her iki grupta da öğretmenlerin, çocukları her gün açık havaya çıkardıkları, Montessori eğitimi veren okullarda günlük açık hava saatinin sadece okuldan okula değiştiği, okul bazında ise her okulun standart bir açık hava saati uygulamasının bulunduğu tespit edilmiştir. MEB programı uygulayan kuramlarda ise açık hava saatinin kurumdan kuruma ve aynı kurumda çalışan öğretmenden öğretmene değişiklik gösterdiği saptanmıştır. Montessori okullarında çalışan öğretmenlerin Montessori eğitimi almış ya da hali hazırda eğitim alıyor oldukları ve bu eğitimleri kurum müdürlerinin verdiği belirlenmiştir. Hem öğretmen (PEAOÖ-Ö) hem de ebeveyn formunun (PEAOÖ-E) "oyun etkileşimi" ve "oyunun bozulması" alt faktörlerinden alınan puanlar arasındaki farklılık anlamlı değilken (p>0,05), "oyundan kopma" davranışında Montessori eğitimi veren ÖOÖEK devam eden çocuklar yönünde anlamlı farklılık bulunduğu görülmüştür (p<0,05). Araştırmaya alınan çocukların akran oyun davranışlarının anne-baba ve öğretmen görüşleri arasında farklılık bulunup bulunmadığı incelenmiş; "Oyun Ektileşimi, Oyunun Bozulması ve Oyundan Kopma" faktörlerinin tümünde anlamlı farklılık olduğu tespit edilmiştir. "Oyun Etkileşimi ve Oyunun Bozulması" alt faktörlerindeki anlamlılık öğretmen görüşü yönünde farklılık gösteriyor iken "Oyundan Kopma" alt faktörü anne-baba görüşü yönünde anlamlı farklılık göstermektedir. Okul öncesi dönem üç-altı yaş arasını kapsayan bir dönemdir. Bu yaş aralığı çocukların akranları ile yoğun bir şekilde oyun oynadıkları bir dönemdir. Akranları ile oyun oynamanın bir sonucu olarak çocuklarda "Oyun Etkileşimi" alt faktörünün altında bulunan "arkadaşı ile oyuncağını paylaşma, oyun esnasında olumlu duygular gösterme" gibi olumlu oyun davranışları ve "Oyunun Bozulması" alt faktörünün altında bulunan "arkadaşının oyuncağını zorla alma, ağlama, kızgınlık gösterme" gibi olumsuz oyun davranışlarını gösterme durumları olağandır. Araştırma sonucundan da anlaşılacağı üzere hem öğretmen hem de anne-baba görüşlerine bakıldığında çocukların olumlu ve olumsuz oyun davranışları okul türüne göre farklılık göstermemektedir. Diğer bir ifade ile Montessori eğitimi alan ve almayan okul öncesi dönem çocuklarının olumlu ve olumsuz sayılabilecek oyun davranışlarında farklılık bulunmamaktadır. Bu sonuca göre diyebiliriz ki çocuğun bulunduğu her yerde oyun da mevcuttur ve bu durum okul türüne göre farklılık göstermemektedir. Fakat okul türüne göre farklılık gösteren nokta ise "Oyundan Kopma" alt faktöründedir. "Oyun grubunun dışında gezinir, oyuna katılmayı reddetme" gibi davranışları içeren "Oyundan Kopma" alt faktörünün puanları Montessori eğitimi alan çocuklarda yüksek çıkmıştır. Yani oyundan kopma davranışı Montessori eğitimi alan çocuklarda daha sık görülmektedir. Bunun sebebi de Montessori eğtiminin ilkelerinden çocuğa saygı, özgür seçim ilkesi, konsantrasyon ile açıklanabilir. Montessori okullarında çocuklar hiçbirşey için oyun oynamak için dahi zorlanmazlar. Dolayısıyla çocuk istediği zaman oyuna katılır, istemediğinde ise sınıfta serbest gezmede özgürdür.

Abstract/Notes: During the past ten years, a total of 3,642 teachers and administrators have attended the Korean Montessori Teacher Training Program (KMTTP). A sample of Montessori teachers (n = 261) and Korean parents (n = 375) from 32 Korean Montessori schools located in the major cities of Korea were surveyed in order to evaluate the effectiveness of this teacher preparation program. The EXPECTATIONS AND GOAL ATTAINMENT QUESTIONNAIRE (EGAQ), designed by the researcher, was the instrumentation used to conduct this study. Major findings demonstrated that 74.5 percent of the teachers surveyed indicated that their main reasons for attending the KMTTP were to increase their professional competency and their knowledge of child development through Montessori philosophy. The correlation between teachers' levels of satisfaction with their preparation and perceived effectiveness of the training program was higher (r =.29, p $<$.05) than between their levels of satisfaction with the program and their perceptions of their preparedness after completion of training (r =.18, p $<$.05). Significant differences existed between perceived effectiveness of the KMTTP and teachers' ages, positions, and years of experience. Older teachers and those with more advanced teaching positions expressed greater satisfaction with the program. Teachers indicated that, upon completion of the KMTTP, they felt more prepared in, than knowledgeable of, Montessori educational methodology. From the parent perspective, the most frequently cited reason (74.3%) for sending their child to a Montessori School was to provide a learning environment that nurtured their child's interpersonal growth. A majority of the parents (58.5%) were very satisfied with the Montessori experience; no parents were dissatisfied or very dissatisfied. In correlating the effectiveness of Montessori education with specific outcomes, parents indicated highest levels of satisfaction in the areas of "concentration" and "academic achievement." A majority of the teachers surveyed (52.8%) encouraged the implementation of the Montessori Teacher Training Program in neighboring countries, with 42.1 percent strongly encouraging implementation. This study demonstrated the need for further development and improvement in the area of Montessori teacher training in Korea.
