We discuss an original study and two replications conducted over 18 years examining the impact of Teacher Study Group (TSG) in Vocabulary, a professional development (PD) approach for improving pedagogy and student learning. Study 1 focused on the design and development of the PD and included a small-scale randomized controlled trial to assess the…

This research study was designed to examine the impact of the incorporation of vocabulary instruction and various teacher strategies by a middle school science teachers team on student science achievement. The researcher focused on the teacher preparation of vocabulary word walls and the inclusion of specific words within individual units of study…

Background: South Africa's "Language-in-Education Policy" (LiEP) provides for bi/multilingual education, but schools are only supported to choose monolingual English language policies from Grade 4 and ignore the learners' home language or languages as resources for learning. Many teachers translanguage orally, using the learners' home…

Communication skills require students to be able to manage, understand, develop, and create orally and in writing. Teaching methods that generally use conventional models of learning activities that are not formed in groups cause students' science communication skills to be lacking, so learning activities are more teacher-centered. This learning…

Biology teachers received professional development to effect instructional changes that ensure student cognitive engagement and knowledge acquisition at higher cognitive levels. We asked the following questions: 1) What are the initial needs of teachers to promote active learner engagement and knowledge acquisition at higher cognitive levels? 2)…

This study documented an interdisciplinary team of grade 8 teachers' utilization and implementation of research-based reading strategies introduced through collaboration during a Professional Learning Community (PLC). This study also investigated the teachers' perspectives on the implementation of research-based strategies, including the factors…

Being scientifically literate is an essential twenty-first century skill for every individual navigating today's complex world and science inquiry skills are seen as an important capability of a scientific literate person. However, teaching science inquiry skills requires specific competences and is often challenging for teachers. Understanding…

This study examines the effectiveness of using augmented reality (AR) in gaining historical empathy skills. AR cards were used in different periods of the history lesson. A mixed design method including pre-test and post-test is used to A mixed methods research design with pre-test and post-test is used to determine the developments in empathy…

Several studies and assumptions support the advantages of presenting pictures before texts, such as the Sequencing Effects of Integrated Model of Text and Picture Comprehension (the Sequencing Effects of ITPC Model) and the Scaffolding Assumption. However, few studies have examined the efficacy of text-first or picture-first multimodal input on…

Productive learning of algebra is supported when students reflect on multiple strategies, compare them and discuss the rationale behind and relative merits of particular strategies. Comparison and Discussion of Multiple Strategies (CDMS) is an instructional approach designed to support these processes in math classrooms. In the current study, 16…

The aim of this study was to compare the 5E learning model with traditional learning methods in terms of their effect on students' conceptual understanding of water subtopics. The participants of the study were grade 8 students of 2021 academic year. While 27 of them were randomly assigned to the experimental group, the other 27 were assigned to…

This Study aim to investigate the effects of integrated inquiry-based and STEM education learning management on Thai grade 8 students' analytical thinking and learning achievement. The research employed a one-group experimental design with 37 grade 8 students from a public school in Khon Kaen Province, Thailand, selected through purposive…

Developing self-regulated learning (SRL) skills among young adolescents is crucial for lifelong learning, and teachers play a vital role in fostering these skills. Problem-solving is a key SRL skill; however, both learners and teachers encounter challenges during the problem-solving process and in evaluating its incorporated strategies. To tackle…

This research presents an investigation on the utilization of Science, Technology, Engineering, and Mathematics (STEM) with Project-Based Learning as experiment class treatment and project-based learning as control class treatment to investigate students' critical thinking in optical instruments lessons, with a particular focus on the development…

Virtual reality (VR) can promote design performance, and may generate a high cognitive load and affect creative design thinking as well. In order to examine the effect of VR application on cognitive load and engineering design creativity, this study recruited 81 eighth-grade students as participants and employed a non-equivalent-groups…
