This paper shows the results of an experiment in which the effects of fibroblast growth factor (FGF), actinomycin D (Act D; an inhibitor of transcription), and cycloheximide (CHX; an inhibitor of translation) were studied on the expression of two genes: a gene called "Fnk" and the gene coding for glyceraldehyde-3-phosphate dehydrogenase (GAPDH).…

This paper highlights some of the challenges and milestones inherent in building partnerships between institutions of higher education and public-school systems from an interdisciplinary approach. It discusses lessons learned from a Mathematics Science Partnership (MSP)-Start Partnership that was funded by the National Science Foundation from 2008…

This report presents Advanced Placement (AP) and International Baccalaureate (IB) examination participation and performance results in Texas public schools for the 2018-19 school year. Data are provided by student characteristics, including race/ethnicity; gender; and economic, at-risk, dyslexia, English learner, foster care, homeless, immigrant,…

This study examined whether student learning outcome measures are influenced by the addition of three-dimensional and digital teaching tools to a traditional dissection and lecture learning format curricula. The study was performed in a semester long graduate level course that incorporated both gross anatomy and neuroanatomy curricula. Methods…

Evaluators must employ research designs that generate compelling evidence related to the worth or value of programs, of which assessment data often play a critical role. This article focuses on assessment design in the context of evaluation. It describes the process of using the Framework for K-12 Science Education and Next Generation Science…

This article discusses the concept "ubuntu", an African worldview rooted in the communal character of African life. Some of the same thinking can, however, be found in various Eurasian and Latin-American philosophies. The concept "ubuntu" is also used in language planning: here, the question of language of instruction is…

This paper demonstrates the positive impact of learning through ecological fieldwork upon children's ability to write, and to write about science. Specifically we have carried out a relatively large-scale study (involving 379 children aged 9-11 years from 8 primary schools in North East England) comparing intervention classes (involved in…

School issues have become increasingly important in public elections and political debates, leading to increased focus on the results students achieve in international large-scale assessments and in the rankings of the involved countries. One of the most important studies of scholastic performance is the Programme for International Student…

This article focuses on the theoretical-methodological question of how to identify reform-induced changes in school mathematics. The issue arose in our project The Evolution of the Discourse of School Mathematics (EDSM), in which we studied transformations in high-stakes examinations taken by students in England at the end of compulsory schooling.…

In an experiment with 65 high-school students, we tested the hypothesis that personalizing learning materials would increase students' learning performance and motivation to study the learning materials. Students studied either a 915-word standard text on the anatomy and functionality of the human eye or a personalized version of the same text in…

The current research aims know the effectiveness of enriching the physics curriculum for students in middle school electronic learning in the development of their thinking and scientific their direction towards physics, sample formed from second grade students in Sinae intermediate school 64 students (32) student as experimental group & (32)…

School grades provide an easily understandable metric to measure the performance of a school. Parents and the general public can use the school grade and its associated components to understand how well each school is serving its students. The school grades calculation was revised substantially for the 2014-15 school year to implement statutory…

The paper attempts to investigate the influence of textbooks on the results of international assessments such as TIMSS [Trends in International Mathematics and Science Study] and PIRLS [Progress in International Reading Literacy Study]. It tries to consider the role and impact of school textbooks on PIRLS and TIMSS performance across countries. As…

We investigate the relationship between teacher licensure test scores and student test achievement and high school course-taking. We focus on three subject/grade combinations--middle school math, ninth-grade algebra and geometry, and ninth-grade biology--and find evidence that a teacher's basic skills test scores are modestly predictive of student…

Survey participation rates can have a direct impact on the validity of the data collected since nonresponse always holds the risk of bias. Therefore, the International Association for the Evaluation of Educational Achievement (IEA) has set very high standards for minimum survey participation rates. Nonresponse in IEA studies varies between studies…
