The objective of this meta-epidemiological study was to explore the impact of attrition rates on treatment effect estimates in randomised trials of chronic inflammatory diseases (CID) treated with biological and targeted synthetic disease-modifying drugs. We sampled trials from Cochrane reviews. Attrition rates and primary endpoint results were…

In this article, we describe the implementation and results of a formative experience with prospective mathematics teachers, focused on developing the competence for didactic-mathematical analysis of curriculum materials, specifically student workbooks related to probability. The research design follows a methodological approach typical of…

This paper provides the first experimental evidence of how admission outcomes in centralized systems depend on strategic college choice behaviors. Centralized college admissions simplify the application process and reduce students' informational barriers. However, such systems also reward informed and strategic college choices. In particular,…

Introduction: Critical thinking is a highly-valued skill in higher education, even though there are few studies that demonstrate its effectiveness on scientific skills of pedagogy students. The purpose of this study was to analyze the effect of a critical thinking program (PENCRIT-RC) on inquiry and probabilistic reasoning skills in pedagogy…

Preventive efforts are necessary to reduce the risk for problem gambling among adolescents, especially among more at-risk youth. However, only a small proportion of the preventive initiatives implemented in the field of adolescent problem gambling are based on robust theoretical models and have been evaluated in their efficacy. By referring to the…

Educational researchers advocate the use of an effect size and its confidence interval to assess the effectiveness of interventions instead of relying on a p-value, which has been blamed for lack of reproducibility of research findings and the misuse of statistics. The aim of this study is to provide a framework, which can provide direct evidence…

Non-compliance is a challenge for practitioners serving children with and without disabilities. Many interventions have been developed to increase compliance. High-probability request sequences (HPRS), an antecedent-based intervention that is based on behavioral momentum theory, is one way to increase compliant behavior. HPRS includes the…

This study employed design-based logistic regression to examine the extent to which attending a science, technology, engineering, and mathematics (STEM) magnet high school, school demographics, and student-level factors explain a student's intent to declare a STEM major in the first semester of college. The results show only student-level factors…

Washington, DC's Opportunity Scholarship Program (OSP), the only federally funded school voucher program in the United States, has provided private school scholarships to low-income students in DC since 2004. From its inception, the program has received significant attention in national debates and has been the subject of rigorous evaluations…

Close to two million first-year undergraduates enroll in developmental education each year. According to recent national estimates, less than half of students who start in developmental education go on to complete gateway courses and less than one-third eventually earn a degree. However, more research is needed to better assess potential…

We estimate the impact of one of the largest college-to-student outreach efforts in the nation, the College Board's Student Search Service. In an oversubscribed "order," colleges receive contact information of a randomly chosen subset of PSAT and SAT exam takers who opt into the service and meet colleges' search criteria from a larger…

Objective: To help mitigate potential gambling harm, responsible gambling information centres are launching across casino venues in North America. The launch of the first such centre in the USA provided an opportunity to achieve three goals: (1) document the centre's reach among casino patrons, (2) generate a comprehensive description of services…

This study examines the long-term relation between an Integrated Student Support (ISS) intervention and postsecondary enrollment and completion for predominantly low-income students of color. We use propensity score weighting to estimate the relation between receiving ISS during elementary school and postsecondary outcomes for 2009-2017 high…

Playing board games is known to improve pre-school student numeracy and many board games are used to motivate and explore concepts in probability. This study investigates whether college students in liberal arts mathematics courses assigned to play the board game "Settlers of Catan" develop a stronger grasp of basic probability concepts…

The academic effects of learning statistics and probability through peer tutoring were analysed in the research reported on here. Two hundred and eight students enrolled in Grades 7, 8 and 9 participated. Fixed- and same-age peer tutoring was implemented 3 times per week for 6 weeks. Each tutoring session lasted approximately 25 minutes. The main…
