    Investigation of teacher opinions about teaching materials designed to support foreign language learning of kindergarten students
    (2021-02) Yüksel, Hacer
    The aim of this study was to investigate the views of English language teachers regarding the use of the Early Language Development System (ELDS) with young learners. This study was primarily designed and conducted as a quantitative study through the administration of a questionnaire developed by the researcher. The instrument included a couple of open-ended items; therefore, some qualitative data analysis was employed as well. The participants included 53 English Language teachers of different grades in Turkey. Data analysis was used to assess the reliability of the instrument through a factor analysis and descriptive and inferential statistics were used to assess and compare responses. The questionnaire was found to be valid and reliable and could be adapted by future researchers. The findings of this study revealed that English Language teachers have positive view of ELDS and indicated that it will benefit young learners.

    Mean acquisition time analysis of fixed-step serial search algorithms
    (IEEE, 2009) Gezici, Sinan
    In this paper, mean acquisition time (MAT) analysis of fixed-step serial search (FSSS) algorithms is presented. First, it is shown that the MAT of an FSSS algorithm can be obtained from that of a conventional serial search (CSS) algorithm after a certain mapping of the uncertainty region. Then, a generic formula for the MAT of FSSS algorithms is derived, which is valid for both dense and sparse channel environments. In addition, MAT formulas for high signal-to-noise ratio scenarios, for large uncertainty regions, and for dense channels are obtained as special cases of the generic solution. Finally, simulation results are presented to verify the analysis and to investigate the factors that affect the optimal step size for FSSS algorithms.
