ASSESSMENT IN ENGLISH AS A FOREIGN LANGUAGE IN PRIMARY SCHOOLS IN TURKEY
(Hacettepe Univ, 2012) Saricoban, Arif; Hasdemir, Esengul; Department of Basic English (Prep School)
Teaching and learning a new language (English) has always been an onerous process demanding time and patience for teachers, students, and related institutions. En this process, teachers aim their students' success by using the most effective techniques and the most suitable curriculum to their needs. These techniques and applications need evaluation in order to find out whether they work or not in terms of taking the students' foreign language proficiency levels to the intended target. At this point, the indispensable part of the whole education process comes forth-assessment. This study aims to scrutinize the current assessment procedure for young learners in primary schools in Turkey.

Fiscal Sustainability from a Nonlinear Framework: Evidence from 14 European Countries
(Springer Science and Business Media B.V., 2019) Hasdemir,E.; Omay,T.; Department of Basic English (Prep School); International Trade and Logistics; Economics
This study examines the fiscal sustainability of 14 European Union (EU) Member countries in the long run. For this purpose, a linear Augmented Dickey Fuller (ADF) and a variety of nonlinear univariate unit root tests are applied to the debt-to-GDP series of the 14 EU Member countries; Belgium, Czech Republic, Denmark, Finland, France, Greece, Hungary, Italy, Netherlands, Poland, Portugal, Romania, Slovakia and Sweden. In addition to that, the nonlinear unit root tests applied in this study are classified according to the source of nonlinearities: (i) time dependent nonlinearity (structural break(s)), (ii) state dependent nonlinearity and (iii) hybrid nonlinearity. Thus, the nonlinearities and their sources in data generating process of debt-to-GDP series of every country can be determined. The findings of this study show that the null of linear unit root cannot be rejected for none of the countries by applying linear ADF whereas it can be rejected as a result of nonlinear unit root tests for considerable number of countries, i.e. 11 out of 14 countries exhibit time dependent nonlinearity, 6 out of 14 exhibit state dependent nonlinearity and 10 out of 14 exhibit hybrid nonlinearity in their relevant data. So, the source of nonlinearities in the relevant data differs according to the country. That is, for testing the fiscal sustainability, the nonlinearities in the data need to be taken into account. Ignoring the nonlinearities in the testing procedure can lead misleading results in the decision of fiscal sustainability in the long run. © 2019, Springer Nature Switzerland AG.
