Japon Ders Araştırması: Türkiye’de İşler mi?

In all international comparison studies, Japanese students, who were at the eighth and seventh grades in Junior high school, performed very well in mathematics. Researchers in mathematics education believe that one of the key reasons for this impressive achievement is the process of lesson study practiced by the Japanese teachers. Thus, the purpose of this paper is to describe what the Japanese lesson study is and then to examine the procedure in terms of how it is planned and conducted by Japanese teachers. The last part of the paper discusses whether teachers in Turkey should work collaboratively within the lesson study model to improve student learning, and in doing so enhance their own teaching practice. Tüm uluslararası karşılaştırmalı çalışmalarda, ortaokul yedi ve sekizinci sınıfta okuyan Japon öğrenciler matematikte çok iyi bir performans göstermişlerdir. Matematik eğitimi araştırmacıları, bu önemli başarının en önemli sebeplerinden birinin, Japon öğretmenler tarafından uygulanan ders araştırması olduğuna inanmaktadırlar. Bu yüzden bu çalışmanın amacı Japon ders araştırmasını açıklamak, Japon öğretmenler tarafından nasıl planlanıp uygulandığını incelemek ve sonunda Türkiye’deki öğretmenlerin bu model içinde öğrenci öğrenimini artırmak ve kendi öğretim uygulamalarını geliştirmek için ortaklaşa çalışıp çalışamayacaklarını tartışmaktır.

İlkokul Öğrencilerinin Modelleme Süreçleri: Suç Problemi

In recent years, mathematics educators have frequently stressed the necessity of instructing students about models and modeling approaches that encompass cognitive and metacognitive thought processes, starting from the first years of school and continuing on through the years of higher education. The purpose of this study is to examine the thought processes of 4th-grade primary school students in their modeling activities and to explore the difficulties encountered in these processes, if any. The study, of qualitative design, was conducted in the 2013-2014 academic year at a Foundation School operating under the auspices of a state university located in a central city in the Black Sea Region of Turkey. A five-week preliminary study was first implemented with designated 4th grade students, after which the criterion sampling method was used to select three students that would be recruited into the focus group. The focus group that was thus formed was asked to work on the model eliciting activity of the Crime Problem and the entire process was recorded on video. A written transcript was made of the video recording, after which the recording and the students' worksheets were analyzed using the Blum and Ferri modeling cycle. The results of the study revealed that over the course of the process, the students tested the hypotheses related to daily life that they had set up, generated ideas of their own, verified their models by making connections with real life, and tried to make their models generalizable. On the other hand, the students had difficulty with understanding the problem and interpreting the qualitative data.Biliş ve biliş-ötesi düşünme süreçlerini içeren model ve modelleme yaklaşımlarının öğrencilere okulun ilk yıllarından yükseköğrenime kadar her seviyede tanıtılmasının gerekliliği son yıllarda matematik eğitimcileri tarafından oldukça çok vurgulanmaktadır. Bu çalışmanın amacı ilkokul 4. sınıf öğrencilerinin model oluşturma etkinlikleri üzerinde düşünme süreçlerini inceleyerek eğer varsa bu süreçlerde karşılaşılan güçlükleri ortaya çıkarmaktır. Araştırma 2013-2014 eğitim-öğretim yılında, Karadeniz bölgesinde büyük bir ilin merkezinde bulunan bir devlet üniversitesine bağlı vakıf kolejinde gerçekleştirilmiş nitel bir çalışmadır. Belirlenen ilkokul 4. sınıf öğrencilerine uygulanan beş haftalık bir ön çalışmanın ardından odak grupta yer alacak üç öğrenci ölçüt örnekleme yöntemi kullanılarak belirlenmiştir. Oluşturulan odak gruba model oluşturma etkinliği olan Suç problemi verilerek çalışmaları istenmiş ve tüm süreç video ile kayıt altına alınmıştır. Video kayıtları yazılı olarak çözümlendikten sonra öğrencilerin çalışma kâğıtlarıyla beraber Blum ve Ferri’nin (2009) modelleme döngüsü kullanılarak analiz edilmiştir. Çalışma sonuçları öğrencilerin süreç boyunca günlük yaşamla ilişkili varsayımları denedikleri, fikirler ürettikleri, modellerinin doğruluğunu gerçek yaşamla ilişkilendirerek test ettiklerini ve modellerinin genellenebilir olmasına çalıştıklarını ortaya koymuştur. Fakat diğer taraftan süreçte öğrenciler problemi anlama ve nitel veriyi yorumlama gibi bir takım güçlüklerle de karşılaşmışlardır

Painting with the Multiple Intelligences: Defining Student Success and Permanence in Art Class

Objectives of the study are to determine the effect of teaching based on multiple intelligence theory (TBMIT) in visual arts class on student success and permanence. Experimental design is used in the study. Study group is composed of students at 8th grade in 2012-2013 educational term at Atatürk Secondary School in Iğdır city centre. Experimental and control groups are made up of 32 and 31 students, respectively. In control group, conventional teaching method was used for expressing the subject of “miniature picture” in visual arts class while in experimental group a teaching method based on multiple intelligence theory (MIT) was applied for 3 weeks in both groups. Success test developed by the researchers was applied to measure success readily after and permanence of the knowledge learned 3 weeks after the experiment. In the comparison of the results obtained from Success and Permanence tests of experiment and control groups, t test was used by considering the statistical analyses of data obtained. It was found form the results that experimental group is more successful than control on the average. According to P test results, experimental group had larger P scores than the control. As a conclusion, MIT was found to affect Success and Permanence of 8th grade students in miniature picture subject in visual arts class

Oil price shocks and stock return volatility: new evidence based on volatility impulse response analysis

We use volatility impulse response analysis to quantify the size and the persistence of different types of oil price shocks on oil and stock return volatility dynamics. Our results show that precautionary demand followed by aggregate demand-side shocks, compared to supply-side ones, have higher positive and persistent effects on stock return volatility whereas the correlations between the two variables are mostly affected by the former shocks

Matematik Öğretmeni Adayları ve Kopya: Hiç Çekmedim Desem Yalan Olur!

The aim of this study is to reveal reasons why prospective mathematics teachers engage in cheating and other forms of academic dishonesty. For this aim, an open-ended question was administered to 48 forth year student teachers. They wrote and submitted one or two-page reflection papers. Their written responses were qualitatively analyzed to get the most common themes. Findings indicated that 81% of them cheated and their most practiced behaviors were writing the crib notes on the desk, copying from another student, and permitting another student to look at their answers. The rest (19%) claimed that they have never cheated for fearing that they could be caught and penalized or because of their moral beliefs and values and being successful on their own.Bu çalışmanın amacı, matematik öğretmeni adaylarının kopya çekme ve diğer dürüst olmayan davranışlara eğilimlerinin nedenlerini ortaya çıkarmaktır. Bu amaca yönelik olarak son sınıfta okuyan 48 matematik öğretmeni adayına bahar döneminin sonunda açık uçlu bir soru yöneltilmiştir. Öğretmen adayların bu soruya verdikleri yazılı cevaplar nitel araştırma teknikleri kullanılarak analiz edilmiştir. Sonuçlar göstermiştir ki öğretmen adaylarının % 81’i bu tip eylemlere başvurduklarını kabul ederken bunu özellikle ‘sıranın üzerine yazma’, ‘arkadaşının kâğıdına bakma’ ve ‘kâğıdını başkasına gösterme’ şeklinde gerçekleştirmişlerdir. Diğer taraftan öğretmen adaylarının % 19’u ise hiçbir şekilde kopya çekmediklerini ifade ederken bunu sebeplerini ‘yakalanıp ceza alma korkusu’, ‘ahlaki değer ve anlayış’ ve ‘kendi başına hak ederek başarıyı elde etme isteği’ şeklinde sıralamışlardır

Motivators and Problems of Being a Global Migrant (Outsource) Soccer Labor in Turkey: A Preliminary Study

The aim of this study was to reveal the motivators and problems of soccer players that pursue their professional careers in Turkey. In this qualitative research, convenience sampling and criterion sampling, which are kinds of nonrandom sampling methods was used to determine the participants. Eight male soccer players from the Genclerbirligi Soccer Team who were complied with the research criteria, voluntarily participated in the study. The demographic information form and semi-structured interview form were used as data collection tools. All interviews were recorded by audio and video recording devices. Data was analyzed by content analysis. The findings showed that; this study was supported the "mercenary", "ambiotis" and "nomadic cosmopolitan" items, which are in typologies that motivates athletes to migrate to a host country. In addition, language and cultural differences were the main problems for migrant athletes. In conclusion, this study demonstrated that besides the items in the typologies, "positive information" can facilitate the migration of athletes to a host country. Furthermore, it expressed the importance of inquiry on the cultural structure of the host country for migrant athletes, in order to minimize negative influences of problems

Comparative physiological and growth responses of tomato and pepper plants to fertilizer induced salinity and salt stress under greenhouse conditions

Fertilizer induced salinity adversely affects plant growth through its ionic and osmotic effects as in ordinary salinity caused by toxic ions (Na, Cl, etc.). In this study, to determine the ionic and osmotic effects of fertilizer induced salinity and NaCl salinity on growth, ascorbic acid, proline and hydrogen peroxide (H2O2) accumulation and stomatal resistance (SR), relative water content (RWC), malondialdehyde (MDA) contents of tomato and pepper plants subjected to different treatments (i.e. control, 40 mM NaCl salinity and excess fertilizer salinity) were investigated under greenhouse condition. The results of this study indicated that similar to NaCl salinity, fertilizer induced salinity significantly reduced the fresh and dry weights of tomato and pepper plants. Relative water content of the plants was decreased by NaCl salinity. Both NaCl and fertilizer induced salinity caused significant increases in proline, MDA, ascorbic acid and H2O2 accumulation, and stomatal resistance of the plants. Salinity achieved by NaCl and fertilizer altered plant growth and plant physiological processes ionically and osmotically in a similar manner

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised
