The randomized control trial (RCT) is the primary experimental design in education research due to its strong internal validity for causal inference. However, in situations where RCTs are not feasible or ethical, quasi-experiments are alternatives to establish causal inference. This paper serves as an introduction to several quasi-experimental…

Creativity and problem-solving are 21st-century skills that students must have to respond to the complex world dominated by technology. Teaching activities integrating Design Thinking (DT) have the potential to cultivate individual skills. As future in-service teachers, pre-service teachers need to understand DT so as to be able to use it in their…

This research aimed to 1) study the factors that affect third-year undergraduate students' creative thinking ability at Baise University, 2) develop an instructional model based on design thinking and brainstorming, 3) compare third-year undergraduate students' creative thinking ability before and after using the instructional model based on…

This study aimed to investigate the teaching effect of the blended BOPPPS based on an online and offline mixed teaching model ("B + BOPPPS") in the course of fermentation engineering in applied universities. The participants were 142 undergraduates majoring from the course of fermentation engineering in Food Science and Engineering in…

This study examined the effect of Discrimination Model (DM)-based group supervision on novice supervisees' counseling self-efficacy and insight levels. The study used a pretest-posttest model with 3X2 quasi-experimental, comparison, and control groups. Eighteen novice supervisees (6 participates in each group) constituted the participants.…

The aim of the current research is to develop a STEM-based digital classroom learning model based on the 21st-century skills and characteristics of elementary school students. To enable the dissemination of this learning model, further research is needed to determine the effect of the STEM-based digital classroom learning model on the 21st century…

The effects of teaching speaking skills through the Flipped Classroom Model on English as a Foreign Language (EFL) students' autonomy, willingness to communicate, and anxiety while speaking English are examined in this study. With a quasi-experimental design, one control group (n = 27) and one experimental group (n = 28) were created for the…

Translating ideas into acceptable sentence is an essential writing production process. Limited sentence construction skills can hinder young writers from expressing ideas as intended or creating sentences that are comprehensible to their audiences. This may also limit other writing production processes, as young writers must devote considerable…

Whether selection processes contribute to group-level disparities or merely reflect pre-existing inequalities is an important societal question. In the context of observational data, researchers, concerned about omitted-variable bias, assess selection-contributing inequality via a kitchen-sink approach, comparing selection outcomes of…

In educational contexts, students often self-select into specific interventions (e.g., courses, majors, extracurricular programming). When students self-select into an intervention, systematic group differences may impact the validity of inferences made regarding the effect of the intervention. Propensity score methods are commonly used to reduce…

Modeling and simulation activities are common in secondary technology and engineering education classrooms. Virtual simulations are used to integrate engineering design into classroom instruction. The performance outcomes of a student's final virtual design usually depend on the level of knowledge application. When applying the learned content to…

Background: The American Psychological Association reports that Generation Z are suffering mentally and physically more than any other group. Purpose: Measure the effects of a 16-week, online college-level "Complementary Therapies in Health Course" through the lens of the biopsychosocial-spiritual model on measures of health and aspects…

The study of literary sociology is still considered boring for most students. The study of literary sociology is only emphasized on the aspect of theory memorizing. Therefore, implementing learning model with CSQ [Contextual and Spiritual Quotient] approach is considered very important to make students active, creative, happy, and have spiritual…

Causal effects are commonly defined as comparisons of the potential outcomes under treatment and control, but this definition is threatened by the possibility that either the treatment or the control condition is not well defined, existing instead in more than one version. This is often a real possibility in nonexperimental or observational…

A common motivation for adding control variables to statistical models is to reduce the potential for spurious findings when analyzing non-experimental data and to thereby allow for more reliable causal inferences. However, as I show here, unless "all" potential confounding factors are included in an analysis (which is unlikely to be…
