When the pandemic COVID -19 led to school closures, many of us had no idea that this disruption would last months and perhaps more than a year. Curriculum-based assessment (CBA) is an assessment process that uses academic knowledge picked directly from the material taught in the classroom. This form of criterion-referenced assessment connects…

The purpose of this study is to investigate the extent to which science process skills are represented in the texts and activities in 3rd, 4th, 5th, 6th, 7th, and 8th-grade science textbooks according to the learning areas of the science curriculum. The document analysis method is adopted in the current study. Course contents and activities in…

In this study, it was aimed to determine the geometry problem posing performance of eighth grade students in different problem posing situations. For this purpose, the convergent parallel mixed model accepted as one of the mixed method designs was preferred. The participants consisted of 151 eighth grade students from the same school. The…

This study aims to investigate the impact of metacognitive awareness and self-efficacy beliefs of middle school students on their level of foreign language learning anxiety by using structural equation modelling. A total of 285 7th and 8th grade students from a middle school in Turkey during the 2018-2019 academic year were included in the study.…

The aim of the study is to compare TIMSS 2011 proficiency levels with the proficiency levels defined by the researchers using cluster analysis for Turkey, Korean, Norway, and Morocco in 4th and 8 th grades in the fields of science and mathematics. Therefore, it is tried to be reached that these cut-off scores for each country can serve the…
