This paper develops a new measure of human capital, calculated as a cohort-weighted average of the quality of education (PISA scores) and the quantity of education (mean years of schooling). Contrary to the existing studies, the relative weights of quality and quantity are estimated (and not calibrated). The quality of education is estimated to be…

It is important to understand the nature of the effect that the COVID-19 pandemic had upon student learning, especially those at risk such as deaf students. The limited communication that many deaf students have at home may mean less support is available for learning remotely. Reading may be one of the areas where progress was diminished. We…

Building on earlier work that explored within-student variation in hours of instruction across school subjects, we investigate the impact of instruction time on student test scores in Switzerland, as measured by the PISA 2009 test. Our results confirm the results of previous studies of a positive effect of instruction time on student performance.…

In an era of expansive school choice, families and students make many comparisons when they consider schools. Policies encourage families to seek out options where average test scores are high or where value-added indicators are strong. When students choose schools with high-performing peers, they often may be at a lower place in the achievement…

There is no comprehensive database of U.S. district-level test scores that is comparable across states. We describe and evaluate a method for constructing such a database. First, we estimate linear, reliability-adjusted linking transformations from state test score scales to the scale of the National Assessment of Educational Progress (NAEP). We…

Research Findings: This study used data from a national sample to examine differences in school outcomes at the end of kindergarten between Head Start children who attended full-day and half-day programs. Propensity scores were used to match children who experienced different intensities of the program on a series of demographic characteristics in…

Nowadays, the importance given to astronomy teaching in science and physics education has been gradually increasing. At the same time, teachers play an important role in remediating the misconceptions about astronomy concepts held by students. The present study aims to determine the misconceptions of pre-service physics teachers (n = 117),…

In the fall of 2011, the state of Nebraska experienced a watershed moment in public education: results of the first standardized mathematics achievement test administered to all students in grades 3-8 and 11 the previous spring (2011) were reported to the public. One state senator referred to some of the results as "shocking." Only four…

This work summarizes the results of two randomized control trails (RCTs) aimed at evaluating the effectiveness of a professional development program for lower secondary school math teachers. The program, called M@t.abel, was financed by the Ministry of Education in Southern Italy with EU funds. It lasts a full school year and it is based on formal…

Above-level testing is the practice of administering aptitude or academic achievement tests that are designed for typical students in higher grades or older age-groups to gifted or high-achieving students. Although widely accepted in gifted education, above-level testing has not been subject to careful psychometric scrutiny. In this study, I…

High School, Aptitude and Achievement Tests have been utilized since 2002 in Saudi Arabia for the purpose of student selection to health sciences and medical colleges. However, longitudinal studies determining the predictive validity of these so-called cognitive tests for in-course performance is lacking. Our aim was to assess the predictive…

PISA 2012 results indicate that school systems that group students based on ability levels tend to have lower performance than those that do not divide students by ability. One way some in the United States have sought to increase equity of opportunity is to mandate enrollment of students in college-preparatory mathematics, i.e., Algebra 1 in…

The number of students from the under-graduate level who have successfully completed their studies is on the increase every year. In the selection process for the best employee-candidate, employers have to take into consideration several factors other than academic excellence, including values that depict EQ or emotional intelligence. This study…

This report focuses on the extent to which students who are academically far off track in fourth or eighth grade in Kentucky catch up by eighth or eleventh grade. We studied three recent cohorts of Kentucky students whose eighth-grade ACT Explore® scores were more than one standard deviation below the ACT Explore benchmark scores associated with…

The purpose of this research is to study the long-run impacts (i.e. on educational attainment) of a freshman math intervention called "double-dose algebra". The intervention was conducted in 2003 and 2004 within the Chicago Public Schools (CPS), a large, poor urban school district. In response to low passing rates in 9th grade algebra,…
