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…

This study examined bias reduction in the eight nonequivalent comparison group designs (NECGDs) that result from combining (a) choice of a local versus non-local comparison group, and analytic use or not of (b) a pretest measure of the study outcome and (c) a rich set of other covariates. Bias was estimated as the difference in causal estimate…

Learning mathematics involves abstract thinking and the use of symbols. To be successful in a mathematics classroom, students must master what symbols mean and how they work. Much prior work has focused on the nature of the external representations used in mathematics instruction, including manipulatives and symbolic representations. In this work,…

To assist preservice elementary teachers in attaining scientific competence, knowledge, and understanding of interdisciplinary concepts, a teacher education model--the combined individual microteaching, modeled teaching, and inquiry-based team-teaching (CIMIT) model--was established, and its effectiveness was evaluated. A quasiexperimental design…

The aim of this study is to investigate the effect of argumentation-based teaching carried out with secondary school 7th grade students on students' scientific process skills. The sample of the study consists of 7th grade students in two different branches studying at a public school in the Central Anatolia Region of Turkey in the 2018-2019…

An augmented reality (AR)-integrated gamification learning approach in an electronics course was developed in this study to help students better understand the concepts while simultaneously increasing their motivation. An experimental study was conducted to examine the effectiveness of the AR-integrated gamification approach on students' learning…

Background Study: The effects of the flipped classroom (FC) on students' academic performance remain ambiguous, and the use of pre-class videos may be one of the main factors hindering students' progress. A software package called GeoGebra has been proposed as a substitute for pre-class videos to aid students' learning. Objective: This study…

This study aimed to determine the difference in environmental literacy skills between the Project-Based Learning (PjBL) learning model and STEM-based PjBL. This research is quantitative research with a quasi-experimental method. The research design used is a non-equivalent pretest-posttest control group design. The dependent variable in this study…

Today, individuals should adapt themselves to the rapidly changing and developing information age and have learning skills. It is only possible by adopting new approaches and strategies instead of traditional teaching methods and techniques. Different learning and teaching approaches are characterized by various methods and designs, such as…

This study examined nutrition intervention curriculum, "Together We Inspire Smart Eating" (WISE). WISE is a research-based, nutrition promotion curriculum specifically designed for pre-school children from families with limited resources. The design was non-randomized treatment/control with standardized pre-/post-test assessments.…

Artificial intelligence aims to restructure and process re-engineering education and teaching processes and accelerate the evolution of the whole education system from information to intelligence. Robotic Process Automation (RPA) robots learn by observing people at work, analyzing user processes repeatedly, and adjusting or correcting automated…

The research aims to know the effect of Active Learning on the concept of mastery of sains learning by fifth grade students at primary school. The method that is used in this research is a quasi-experimental research. The aspect being measured in this research was comparing two learning groups. Experiment group was exposed to Active Learning Model…

Spiritual intelligence involves a search to find and create meaning based on a deep understanding of existential tenets and the ability to reach higher meanings and values. Despite the growing interest among scholars to study the development of this construct and its impact on one's life, it has remained an under-researched area of inquiry,…

This study compares the effects of object-oriented and robot programming activities on programming achievement, abstraction, problem solving, and motivation. In the study, two consecutive experimental cases were conducted to examine the consistency of findings. The research sample comprises 81 tenth-grade students undergoing vocational secondary…

Shoulder pathologies among the adult population are increasing, causing a high concern in health-educational institutions. The aim of this research is to take a step further and to conduct a detailed study of the relationship between the application of Jackins technique and a postural education program for people affected by shoulder problems.…
