Methods to handle ordered-categorical indicators in latent variable interactions have been developed, yet they have not been widely applied. This article compares the performance of two popular latent variable interaction modeling approaches in handling ordered-categorical indicators: unconstrained product indicator (UPI) and latent moderated…

Deaf and hard of hearing (DHH) students often experience systemic barriers to academic success, especially low expectations of what they know and can do. Longitudinal data analysis is critical to understanding how academic achievement for DHH students progresses over time and where they may need additional support on their academic journey to…

Twenty-first-century skills are increasingly recognized as critical skills that today's students must develop to adapt to increasingly rapid world changes. This research aims to test the effectiveness of the STEM-EDELCY learning model to improve students' 21st-century skills. This research involved 285 junior high school students (aged 12-13) from…

Dynamic assessment (DA) integrates assessment and instruction into an organic unity aimed at promoting learner development through mediation sensitive to the individual's (or in some cases, a group's) current abilities. This article reports on the construction of a model of mediation framed within DA for English-as-a-foreign-language listening…

Writing is a fundamental skill in English language learning that requires the application of effective instructional strategies. Various strategies have been implemented in writing classrooms, including writing strategies, summarization, collaborative writing, specific product goals, word processing, sentence combining, prewriting, inquiry…

Drawing on a social identity framework of mathematical development, the authors present a model, Improving Girls' Math Identity (IGMI), designed to address two key "leaks" in the female STEM pipeline: undergraduate and middle school. IGMI involves a supportive professional development network for undergraduate women preparing to…

Operationalism, representationalism, and pragmatism are three major philosophies of measurement in psychology and education. These philosophies play important roles in designing and conducting measurements, as well as interpreting results. When measurement results are available, validity evidence plays important roles in supporting the…

It is important to raise enterprising individuals in STEM fields so that countries have individuals, who will play a role in global competition, and this is possible with effective STEM education. This research aims to reveal the impact of STEM activities, which were designed using the 6E learning byDeSIGN™ model, in terms of developing middle…

The objective of this research is to develop a model for life skills training through the strengthening of academic, personal, social, and career competencies for middle school students. We designed this model to equip students with the necessary skills to navigate the complexities of life's challenges. Design-Based Research (DBR) serves as a…

Self-direction skill (SDS) is an essential 21st-century skill that can help learners be independent and organized in their quest for knowledge acquisition. While some studies considered learners from higher education levels as the target audience, providing opportunities to start the SDS practice by K12 learners is still rare. Further, practicing…

Sustainability consciousness is an outcome of Education for Sustainable Development, which was launched by UNESCO in 2014 to create a society with sustainable living behavior. The purpose of this research is to analyze the impact of the RADEC learning model oriented ESD on students' sustainability consciousness. This research involved 150…

Teachers play a critical role in supporting students' mathematical engagement. There is evidence that meaningful student engagement occurs more often in student-centered classrooms, in which the teacher and the students mutually share mathematical authority. However, teacher-centered instruction continues to dominate classroom discourse, and…

The main goal of this research is to study the effect of modelling with system dynamics on learning. Specifically, this research studies if using inductive or deductive learning methods applied during modelling with system dynamics has any effect on problem solving skills of students. This research has three other goals: Firstly, the successful…

Thinking development processes among high-school students is an important and significant issue that has been widely investigated (Leviathan, 2012; Ball, 1996; De Risi, 2015). A few studies discuss the development of mathematical thinking as this field contains additional difficulties to the traditional factors, teachers, students, and parents,…

The study aimed to evaluate the 8th grade mathematics curriculum in Turkey, which was revised in 2016-2017 school year, and implemented from 2017-2018 school year on. In the study the Eisner's educational connoisseurship and criticism model was utilized. The participants of the study comprised 15 secondary school mathematics teachers selected by…
