Our study tests the effectiveness of STEM Alliance, a student organization aimed at increasing academic and social support for students pursuing STEM majors. STEM Alliance offered weekly, extracurricular activities aimed at preparing students for graduate school and STEM careers. Students attending STEM Alliance events showed greater academic and…

Purpose: Among the gold standards in human resource development (HRD) research are studies that test theoretically developed hypotheses and use experimental designs. A somewhat typical experimental design would involve collecting pretest and posttest data on individuals assigned to a control or experimental group. Data from such a design that…

Background: Although we have learned a good deal from lottery-based and quasi-experimental studies of charter schools, much of what goes on inside of charter schools remains a "black box" to be unpacked. Grounding our work in neoclassical market theory and institutional theory, we examine differences in the social organization of schools…

This two-group quasi-experimental study investigated the effects of the Online Advance Organizer Concept Teaching Material (ONACOM) integrated with inquiry teaching and expository teaching methods. Grade 7 students' posttest performances on the light unit achievement and light unit attitude tests controlled for gender, previous semester science…

When randomized experiments are infeasible, quasi-experimental designs can be exploited to evaluate causal treatment effects. The strongest quasi-experimental designs for causal inference are regression discontinuity designs, instrumental variable designs, matching and propensity score designs, and comparative interrupted time series designs. This…

This study considered the impact of state-level guaranteed tuition programs on alternative student-based revenue streams. It used a quasi-experimental, difference-in-difference methodology with a panel dataset of public four-year institutions from 2000-2012. Illinois' 2004 "Truth-in-Tuition" law was used as the policy of interest and the…

This chapter presents a case study of scaling up the T-STEM initiative in Texas. Data come from the four-year longitudinal evaluation of the Texas High School Project (THSP). The evaluation studied the implementation and impact of T-STEM and the other THSP reforms using a mixed-methods design, including qualitative case studies; principal,…

Attendance, behavior, and academic outcomes are important indicators of school effectiveness and long-term student outcomes. "Multi-tiered systems of support" (MTSS), such as "School-Wide Positive Behavior Interventions and Supports" (SWPBIS), have emerged as potentially effective frameworks for addressing student needs and…

Eighth grade math students must pass a standards based test to be promoted to the next grade. Students who were at risk of failing the state's annual test faced impending retention. The purpose of this quasi-experimental study was to see if an intensive nine-week (55 min per day) remedial Math Connection (MC) class for 67 suburban, eighth grade…

Student achievement in reading comprehension has been an important topic for the past several years due to the importance of reading in education. School districts in South Carolina have had enormous amounts of pressure put on them to increase student reading comprehension through the implementation of SLOs and the Read to Succeed initiative. The…

A total of 29 low-income, prekindergarten children, attending a summer school program, participated in a six-week shared book-reading (SBR) intervention. Children were randomly assigned to one of four conditions that varied in the extent to which teachers embedded an explicit emphasis on print (code-focused interactions), vocabulary…

This article examines the process and outcome of a life design counseling group intervention with students in Grades 9 and 12. First, we applied a quasi-experimental methodology to analyze the intervention's effectiveness in promoting career certainty, career decision-making, self-efficacy, and career adaptability in a sample of 236 students.…

This study aims to develop and examine a civic education textbook model based on living values education in order to foster the development of junior high school students' characters. This research employs Research and Development approach with an explorative method being used at model development stage and experiment method at model testing…

Obtaining oral communication competency is an important skill for engineering students to prepare them for interacting and working in any professional setting. For engineers, it is also important to be able to present technical information to non-technical audiences. To ensure oral competency, a non-graded formative assessment approach using video…

The current study examines whether the engagement of mathematics teachers in modelling activities and subsequent changes in their conceptions about these activities affect their beliefs about mathematics. The sample comprised 52 mathematics teachers working in small groups in four modelling activities. The data were collected from teachers'…
