Early math skills are a strong predictor of later achievement for young children, not only in math, but in other domains as well. Exhibiting strong math skills in elementary school is predictive of later high school completion and college attendance. To that end, the Making Pre-K Count and High 5s studies set out to rigorously assess whether…

This report presents the results of a thorough study conducted by American Institutes for Research (AIR) to investigate the cost of providing an "adequate" education to California students attending public elementary, middle, and high schools. The study addresses the following question: "What is the cost of providing all California…

A recent study suggests a correlation between idiopathic scoliosis in adolescence and eating disorders. However, this does not correspond with our clinical experience in the same population. The aim of this study was to verify the correlation between scoliosis and eating disorders in adolescence. A cross-sectional study was designed including 187…

This study examines whether the self-concepts, social skills, problem behaviors, and loneliness levels of students with special educational needs (SEN) in inclusive elementary classrooms differ from those of students without special educational needs (non-SEN). This study also aimed to identify the roles of self-concept, social skills, and problem…

In assessing the teaching practice of preservice teacher candidates, observers, particularly trained observers, will readily identify those who are exceptionally effective or ineffective. The anticipation is that university supervisors and mentor teachers will agree on who demonstrates extraordinary performance for a preservice candidate and who…

The current study applied the person-fit statistic, l[subscript z], to data from a Canadian provincial achievement test to explore the usefulness of conducting person-fit analysis on large-scale assessments. Item parameter estimates were compared before and after the misfitting student responses, as identified by l[subscript z], were removed. The…

The purpose of this study is to compare the levels of life quality, depression and loneliness among the students of the Faculty of Sports Sciences (FSS), national wrestlers and non national wrestlers in terms of some demographic variables. The participants of the study included 37 students from the Faculty of Sports Sciences of Ondokuz Mayis…

Considered a non-academic factor that is not necessarily measured by academic indicators of college and career readiness (e.g., grade point average, college admissions exams scores), critical thinking is an important aspect of 21st century learning and thus should be embedded into secondary school instruction and assessment. In this study,…

The aim of this study was to evaluate the effect of problem-based learning (PBL) on university students' satisfaction with and academic performance in a course on epidemiology and social and demographic health. The participants in this interventional study were 529 students (272 in the intervention group and 257 in the control group) enrolled in a…

Error analyses using a multidimensional measure were conducted on the misspellings of Kindergarten children speaking English as a first (EL1) and English as a second language (ESL) in order to detect any differences in early spelling ability between language groups. Oral vocabulary, syntactic knowledge, phonological processing, letter/word…

This article focuses on analysing the effect of educational differentiation policies of OECD educational systems on socioeconomically disadvantaged students, based on data from PISA 2009. The analysis is conducted on the basis of a definition of two subgroups of disadvantaged students: those that achieve high scores, and those obtaining scores…

Demand for online learning has increased in recent years due to the convenience of course delivery. However, some students appear to have difficulties with online education resulting in lack of completion. The study utilized a quantitative approach with archival data. The factors of achievement and demographics were compared for face-to-face and…

Researchers have become increasingly interested in programs' main and interaction effects of two variables (A and B, e.g., two treatment variables or one treatment variable and one moderator) on outcomes. A challenge for estimating main and interaction effects is to eliminate selection bias across A-by-B groups. I introduce Rubin's causal model to…

Most institutions of higher education have some system in place for collecting student ratings of instruction (SRI) data from classes on a systematic basis. SRIs are a relatively simple way of gauging student perceptions of teaching and the course. Since the initial development of IDEA SRI in 1975, much has changed about higher education. Many…
