The use of paper books for teaching and learning has many limitations in terms of cost and efficiency. The advantages of digital textbooks are emphasized in many studies. Researchers say that the use of digital textbooks as mediators of the 21st century provides the ability to solve a variety of educational and learning problems for the future.…

While the long-term societal costs for youth with disruptive behavior disorders are well documented, there is a dearth of information about the comprehensive costs of implementing even the most well-regarded early intervention programs, and the costs of scaling effective interventions are even less well understood. This study estimated the costs…

Decreasing class sizes, even by as little as one student, comes with a price tag. It is possible to "pay" for this increase by compensating with one of the other factors influencing the salary cost of teachers: lower teachers' salaries, less required instruction time for students or more teaching time for teachers. Across OECD countries…

This paper evaluates the impact on dropout rates of a policy change in Mexico that eliminates grade retention for all first to third-grade students, causing a sharp reduction in repetition rates. I use a 12-year panel of schools to exploit such variation and estimate Difference-in-Difference models showing an average decrease in dropout rates of…

The purpose of this qualitative, phenomenological study is to identify recruitment tools, which may effectively increase international student enrollment at a public, state-assisted university in Texas that does not actively recruit internationally through international travel or dedicated recruitment plans structured for international students.…

This paper reports the results of a randomized controlled trial evaluating "We Have Skills," a brief curriculum designed to teach early elementary students academic and social skills as well as improve teacher efficacy in classroom management. Intervention efficacy was tested with 127 teachers, randomly assigned to condition, and 2,817…

Federal mandates (e.g., Every Student Succeeds Act [ESSA], 2015) require special educators to use evidence-based practices (EBP) when working with K-12 students. However, for this expectation to become a reality, teacher educators must make changes in educator preparation program (EPP) curriculum, policy, coursework, and clinical experiences (Kolb…

This study examines costs of public master's colleges and universities in the United States by employing panel data on 248 institutions spanning fiscal years 2004-2012. Our analyses estimates a flexible fixed cost quadratic function that also accounts for spatial interdependency to empirically investigate the economies of scale and scope with…

The miniaturization of flow injection analysis devices presents several improvements related to analytical procedures. However, a cost reduction and simplification are required to allow extensive use in undergraduate teaching laboratories. Here we present a low cost microfluidic electroanalytical device composed only of interlocking toy blocks,…

The shift to online learning has challenged instructors to create courses that are as engaging online as they are in person. As many faculty prepare for online learning again this fall, open educational resources (OER) can be part of the solution to help students stay safe and be successful. OER are free and openly licensed online teaching and…

Anxiety in autism is an important treatment target because of its consequences for quality of life and well-being. Growing evidence suggests that cognitive behaviour therapies and mindfulness-based therapies can ameliorate anxiety in autism but cost-effective delivery remains a challenge. This pilot randomised controlled trial examined whether…

This study examined the cost-effectiveness of a 50-lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, ROOTS. The study utilized a randomized block design with 1,251 at-risk students within 138 classrooms randomly assigned to one of two active treatment conditions (small groups of either two…

This paper reports on the results of the design and implementation of a didactic device proposed by a mathematics teacher-trainee. This student did a course designed for didactic-mathematical training with the aim of adopting a non-traditional didactic model based on research, while linking mathematics with other disciplines. The teacher-trainee…

This paper evaluates the academic impact of a growth-mindset intervention on students starting the secondary level in public schools in urban Peru. ¡Expande tu Mente! is a 90-minute school session aimed at instilling the notion that a person's own intelligence is malleable. Students in schools randomly assigned to treatment showed a small…
