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 study investigated whether the Key Concepts in Science Project influenced the pedagogical development of Natural Science teachers. Grounded in social constructivism, emphasising collaborative learning and hands-on interaction, the study employed qualitative methods to collect empirical data. Through photographic evidence, field notes, and…

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…

The objectives of this research are: (1) to develop a flipped classroom learning plan using inquiry-based learning on the topic of substance separation for Grade 8 students, to achieve effectiveness according to the 75/75 criteria; (2) to compare science process skills and learning achievement before and after implementing the developed learning…

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)…

Higher-level questioning is an instructional method often recommended to challenge cognitively gifted students. However, professional development is needed to help teachers improve their ability to ask higher-level questions. Therefore, we developed an intervention based on Bloom's taxonomy, consisting of a 2-h session in which teachers learn how…

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…

Many studies show the value of local history, especially multicultural history, to youth development and student learning outcomes. Incorporating local history into classrooms improves students' ability to question historical significance, analyze primary sources, contextualize their historical thinking, and embrace the learning process as their…

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…

This study aimed to provide professional development in vocabulary instructional practices and analyze the impact on student achievement. This one group pretest-posttest research design study evaluated the effectiveness of direct vocabulary instruction on eighth-grade students' academic achievement, identified the academic achievement gained in…

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…
