In this study, framed within a sociocultural theory of mind, we explore the role of languaging in mediating between students' understanding of a grammatical concept and their written production of the forms related to that concept. The development of scientific concepts, in this case of the concept of voice in French, involves the use of language…

This paper introduces a utilitarian confidence testing statistic called Risk Inclination Model (RIM) which indexes all possible confidence wagering combinations within the confines of a defined symmetrically point-balanced test environment. This paper presents the theoretical underpinnings, a formal derivation, a hypothetical application, and…

The assessment of differential item functioning (DIF) in polytomous items addresses between-group differences in measurement properties at the item level, but typically does not inform which score levels may be involved in the DIF effect. The framework of differential step functioning (DSF) addresses this issue by examining between-group…

The current study examined the validation and alignment of the PASA-Science by determining whether the alternate science assessment anchors linked to the regular education science anchors; whether the PASA-Science assessment items are science; whether the PASA-Science assessment items linked to the alternate science eligible content, and what…

The Condition of Education is a congressionally mandated annual report summarizing important developments and trends in education using the latest available data. The 2019 Condition of Education report presents 48 indicators on topics ranging from prekindergarten through postsecondary education, as well as labor force outcomes and international…

The "Comparative Indicators of Education" report series has been published on a biennial basis since it began in 2002, although this year's is the first to expand its focus to the G-20 countries, having previously been focused on the G-8 countries. "Comparative Indicators of Education in the United States and Other G-20 Countries:…

This research was designed to study the effect of a professional development program in place-based science education on teacher and student learning in rural elementary schools in Thailand's northern Lampang province. Based on the results of a pilot study conducted in 2008 at one school, which was then followed by a needs assessment conducted…

The aim of this study is examining the effect of the using scientific literacy development activities on students' achievement. The study was carried out in a primary school in Buca Izmir for 2010-2011 academic years. System of our body was chosen as a study topic in our search which took 6 weeks. Pre-post test semi experimental control model was…

This paper provides practical guidance for researchers who are designing and analyzing studies that randomize schools--which comprise three levels of clustering (students in classrooms in schools)--to measure intervention effects on student academic outcomes when information on the middle level (classrooms) is missing. This situation arises…

Educators have recently come to consider inquiry based instruction as a more effective method of instruction than didactic instruction. Experience based learning theory suggests that student performance is linked to teaching method. However, research is limited on inquiry teaching and its effectiveness on preparing students to perform well on…

Policymakers and academics are increasingly interested in applying financial incentives to individuals in education. This paper presents evidence from a pay for performance program taking place in Coshocton, Ohio. Since 2004, Coshocton has provided cash payments to students in grades three through six for successful completion of their…

To determine whether teaching an introductory physics course with a traditional lecture style or with Just-in-Time teaching (a student-centered, interactive-engagement style) will help students to better understand Newtonian concepts, such as Newton's Third Law, 222 students in introductory physics courses taught by traditional lecture styles and…

This paper reports on an investigation of the effectiveness an intervention using several different methods for teaching solution chemistry. The teaching strategy comprised a four-step approach derived from a constructivist view of learning. A sample consisting of 44 students (18 boys and 26 girls) was selected purposively from two different Grade…

We report on the development and use of an analytical framework designed to articulate the language demands English learners (ELs) encounter on performance assessments such as those used in inquiry-based science classrooms. The Science Assessment Language Demands (SALD) Framework, grounded in functional and interactional views of language and…

Students in 4 Canadian high school physics classes completed instructional sequences in two key physics topics related to motion--Straight Line Motion and Newton's First Law. Different sequences of laboratory investigation, teacher explanation (lecture) and the use of computer-based scientific visualizations (animations and simulations) were…
