This study finds that, breaking with decades of slow improvement, U.S. reading and math scores on the National Assessment of Educational Progress (NAEP) and other assessments have seen historic declines since most states implemented national Common Core English and math curriculum standards six years ago. This descriptive analysis is designed to…

How, when and what kind of learning takes place are key questions in all educational environments. School graduates are expected to have reached a development level whereby they have, among many fundamental skills, the ability to think critically, to plan their studies and their future, and to integrate knowledge across disciplines. However, it is…

In this study, it is aimed to adapt the Scientific Reasoning Scale (SRS) into Turkish. The translated form has been provided to the students enrolled at different levels together with a form in which they were requested to present what they have understood and the reason of their responses. It was seen that the explanations of students to one item…

According to the Organisation for Economic Co-operation and Development (OECD), environmental literacy is the intended outcome of environmental education. Following this postulate, this study aims to investigate the presence of a spatial correlation between the OECD environmental literacy index and the levels of empirical knowledge production in…

Genetics is considered as one of the topics in science that students have difficulty and trouble in understanding. This study used study guide as an intervention tool to address the difficulties of students in learning genetics concepts. The main purpose of this study was to determine the perceptions of students on the effectiveness of study guide…

Recent studies emphasize the importance of socio-emotional skills, but little is known about how everyday classroom practices impact development of these skills. Using data from the Czech Republic, we show that modern practices such as working in small groups improve these skills. Intrinsic motivation and self-confidence are particularly…

Is it possible to compare the results in assessments of mathematics across countries with different curricula, traditions and age of starting school? As part of the iPIPS project, a Russian version of the iPIPS baseline assessment was developed and trial data were available from about 300 Russian children at the start and end of their first year…

The purpose of this report is to examine the performance of assessment items designed to measure elementary teachers' content knowledge for teaching (CKT) science as part of the ETS® Educator Series. The Elementary Education: CKT Science assessment is 1 component of licensure examination through the PRAXIS® assessments. The Elementary Education:…

Terms to be familiar with before you start to solve the test: gene targeting, knock-out mutation, bacteriophage, complementary base-pairing, homologous recombination, deletion, transgenic organisms, promoter, polyadenylation element, transgene, DNA replication, RNA polymerase, Shine-Dalgarno sequence, restriction endonuclease, polymerase chain…

To ensure the statistical result validity, model-data fit must be evaluated for each item. In practice, certain actions or treatments are needed for misfit items. If all misfit items are treated, much item information would be lost during calibration. On the other hand, if only severely misfit items are treated, the inclusion of misfit items may…

The Kruger-Dunning effect was studied as it related to performance in chemistry courses based on student differences in academic background. Student major was chosen as the classification to look at the effect of students with different interests/specializations. Chemistry majors tended to predict lower performance than biology majors, while…

This study was aimed to examine the relation between the STEM (Science, Technology, Engineering and Mathematics) career interests and science process skills of middle school seventh grade students. Method of this study was the relational survey method. The study was conducted on the basis of voluntariness and participants were 133 seventh grade…

The purpose of this work is to study the effectiveness of our introductory mechanics instructions in changing students' misconceptions about Newtonian concepts. We gave the force concept inventory (FCI) test to 341 of our students twice, before and after instructions. The data were analyzed using a method first reported by Martín-Blas "et…

The understanding of what makes a question difficult is a crucial concern in assessment. To study the difficulty of test questions, we focus on the case of PISA, which assesses to what degree 15-year-old students have acquired knowledge and skills essential for full participation in society. Our research question is to identify PISA science item…

This study of science standards of all 50 states and 1958 American early adolescents asked whether there is agreement among states about a science topic, lunar phases, that appears in all recent national standards documents, is of cultural significance, and has been widely studied for misconceptions held by children and adults. Secondly, we asked…
