Science, technology, engineering, and mathematics (STEM) education has become an international priority. STEM education provides students with interdisciplinary knowledge and promotes the cultivation of high-level skills. However, STEM training opportunities for teachers are rare, which results in fewer opportunities for primary and secondary…

Despite the importance of replication, it remains rare in the interactive learning research community. In this paper, we attempt to replicate recent quasi-experimental results suggesting that the ALEKS intelligent tutoring system is effective at improving student course outcomes in higher education (Mojarad et al., 2018). In this paper, we conduct…

Data sets from large-scale longitudinal surveys involving young children and families have become available for secondary analysis by researchers in a variety of fields. Researchers in early intervention have conducted secondary analyses of such data sets to explore relationships between nonmalleable and malleable factors and child outcomes, and…

Background: Special education services are individualized supports provided to students with disabilities (SWD) that should help them make appropriate educational progress given their abilities, educational needs, and goals (Endrew F. v. Douglas County School District, 2017). Concerns about the benefits of these services have emerged given the…

We consider situations in which public charter school lotteries are neither universally conducted nor consistently documented. Such lotteries produce "broken" Randomized Control Trials, but provide opportunities to assess the internal validity of quasi-experimental research designs. Here, we present the results of a statewide charter…

College professors have adopted numerous strategies for teaching undergraduates, yet few researchers provide empirical evidence students' learning actually increased because of the instructional innovation. Assessment of pedagogy is frequently subjective and based on comments from students or faculty. Consequently, evaluating the effectiveness of…

This study examined the effects of using Microsoft Mathematics on students' attitude, conceptual understanding, and procedural skills in Differential Calculus. A quasi-experimental research design was used in which two different learning environments were compared. The participants of the study were two classes of Electrical Engineering students…

Purpose: The purposes of this study were to: (a) examine the impact of the Silverman and Solmon article (1998) on how researchers handle the unit of analysis issue in their field-based intervention research in physical education in the United States and summarize statistical approaches that have been used to analyze the data, and (b) provide…

The rapid advances of China's universities in major international league tables are generally believed to be an accomplishment of Project 985. A quasi-experimental study was, therefore, undertaken to test the belief and to evaluate the effectiveness of this policy intervention, using 15-year panel data between 1998 and 2013. Results from a…

A semantic diagram tool is proposed in this study in order to structure collaborative problem solving (CPS) based on cognitive load theory (CLT). To investigate its effects on transaction cost and the deepening of user understandings, a comparative quasi-experiment was designed and conducted with 49 participants from a university in East China.…

Peer feedback is widely used to train assessment skills and to support collaborative learning of various learning tasks, but research on peer feedback in the domain of mathematics is limited. Although domain knowledge seems to be a prerequisite for peer-feedback provision, it only recently received attention in the peer-feedback literature. In…

We argue in this article that there are conditions in which publication of negative results can make a useful contribution. Three small-scale examinations of journal publication criteria for publishing negative results were conducted. We first reviewed 29 journals from education and school/counseling psychology to assess author submission…

The present study sought to evaluate the effects of a reading strategy instructional program on the reading competence of third-grade students. Students were instructed in fluent and strategic reading by trained research assistants in whole class settings and subsequently worked on expository text material together with peers. Their reading…

Randomized controlled trials (RCTs) and quasi-experimental designs like regression discontinuity (RD) designs, instrumental variable (IV) designs, and matching and propensity score (PS) designs are frequently used for inferring causal effects. It is well known that the features of these designs facilitate the identification of a causal estimand…

The objective of this study was to examine how individual interest and knowledge acquisition are causally related. Three hypotheses were tested using a cross-lagged panel analysis (N = 186) and two quasi-experimental studies (N = 68 and N = 108) involving students from schools in Singapore. The first hypothesis is the broadly shared standard…
