This study systematically reviews randomly selected 155 experimental studies in education field originated in the Republic of Turkey between 2010 and 2020. Indiscriminate choice of sample size in recent publications prompted us to evaluate their statistical power and precision. First, above and beyond our review, we could not identify any large-scale experiments such as cluster-randomized or multisite randomized trials, which overcome shortcomings of small-scale experiments, better suit to the organizational structure of the education field, nevertheless require far greater effort and financial resources. Second, none of the small-scale experiments has reported or conducted ex-ante power analysis. Third, results indicate that studies are sufficiently powered to detect medium to large effects (0.50 < Cohen’s d < 0.80), however they are underpowered to detect small effects (Cohen’s d ≤ 0.20). In other words, they are precise enough to detect medium effects and above (MDES ≥ .50). Finally, trends in the past ten years indicate precision remained unchanged. Findings should be interpreted in light of minimum effects in education that are relevant to education policy and practice. We emphasize the importance of conducting ex-ante power analysis, and encourage the reporting of standardized variance parameters and attrition rates to inform future studies of similar kind.

The Republic of Turkey was founded in 1923. In the first 20 years of its existence, the political leadership of the republic embarked on a process of nation building in Anatolia and at the same time changed the face of Turkish society, stamping on it a particular brand of secular modernity. This article tries to find out what were the common characteristics of the small band of men who made up the leadership of the republic and to what extent their shared background and experience can help explain the course they charted for Turkey after its creation. One of the conclusions is that Turkey, although located geographically for more than 90% in Asia, is in fact a creation of Europeans, who shaped the country after their own image.

The right to work has been recognized as a fundamental human right in almost all international human rights documents and in the constitutions of many countries. This right has been recognized and guaranteed as a fundamental human right also in the Constitution of the Republic of Turkey. However, not only recognizing and guaranteeing "work" as a fundamental human right but also regulating its implementation and functioning within the framework of laws is of great importance. The concept of overwork is a concept that has been mentioned in the Labor Law regarding the implementation and functioning of the concept of work and it is regulated in our Labor Law No. 4857. In order to talk about overwork, a limited working time is required. In this context, upon determining the maximum number of hours a worker can work per week by drawing a limit on working hours in Labor Law No. 4857, overwork, which is the subject of work exceeding this period, is defined. Furthermore, the types of overwork that arise depending on the reasons for overworking, as well as the jobs that cannot be overworked, are regulated in the same Law.

One of the most significant, but unstudied, aspects of the reforms accomplished in the Ottoman Empire during the nineteenth century under the leadership of the Tanzimat statesmen and of Sultan Abd ul-Hamid II was a radical transformation of the traditional Ottoman tax structure and the introduction of the system that has remained in force, with relatively few changes, to the present day, at least in the Republic of Turkey.

Since the 1950s, historiographical trends in scholarship have re-considered the dissolution of the Ottoman Empire and the subsequent nation-state building of the Republic of Turkey. The social and political evolution of the imperial system into a nation-state has been alternatively explained through geopolitical pressures, domestic resistance, the expanding economy and modernism in Europe, and the inability of the Ottoman establishment to cope with the rapid changes of the nineteenth century. Constructing one holistic narrative of a vast time period of upheaval is a difficult endeavor for any scholar. In the case of the fall of the Ottoman Empire and the rise of the Republic of Turkey, ethno-religious networks, two world wars, geopolitical competition between the great powers, regional and pan-regional insurgencies, demographic displacement, nationalist fervor sweeping through the Balkan and Arab provinces and into Anatolia, and finally the Kurdish armed resistance renders succinct historical narratives all but impossible to achieve. Thus, while there are many stories of the end of the Ottoman Empire, an overview of the issues for students and general audiences is a much needed, but audacious, undertaking. Yet for understanding the Middle East and Southeastern Europe today, a critical narrative must be told in all its complexity.
