Early years experiences in quality thinking and socialization are critical to the optimal development of children, and Quality Early Childhood Education (QECE), is crucial in achieving these quality developments. However, several literatures suggest that there is a general lack of Teaching and Learning Materials (TLMs) in Sub-Saharan Africa, Ghana…

Two of the Standards for Mathematical Practice (SMP) in the Common Core State Standards for Mathematics (CCSSM; NGA Center and CCSSO 2010), "Look for and use structure" (SMP 7) and "Look for and express regularity in repeated reasoning" (SMP 8), are particularly abstract and sometimes clear only in the mind. For a given…

The COVID-19 pandemic has resulted in school closures all across the world, and lots of students have shifted from conventional classrooms to online learning. With the help of ICT technologies nowadays, learning online can be more effective in a number of ways. However, most of the online learning environments without instructors' attention may…

Together, this dissertation describes the combined importance of visuality, pedagogy, and forces like power in deaf education. It documents a multimethod qualitative research design with case study and grounded theory methods to examine conflicting issues about "how" and "why" vision is used in deaf pedagogy. Initially,…

In the age of big data, interactive data visualizations are becoming increasingly prevalent. The ability to focus on subsets of data is essential for exploring large temporal, geospatial, topical, and network datasets. In order to categorize all parts of data visualizations, various attempts have been made to build frameworks for how to interpret,…

This study examines the opportunities presented to high school chemistry students through argument driven inquiry (ADI) and how these opportunities led to changes in student understanding. Lesson plans and videos were analyzed to determine how much time students spent arguing from evidence including constructing and argument board, discussing with…

Traditionally, content assessments have been carried out through written language. However, the latest standards in U.S. K-12 education expect all students, including English learners (ELs), to demonstrate their content learning using multiple modalities. This study examined the performance of fifth-grade students at varying levels of English…

The Hertzsprung-Russell diagram (HRD) is a fundamental representation in stellar physics. It contains information about key properties of stars and allows inferences about stellar evolution. The use of the HRD is an important disciplinary activity in astrophysics. For example, it is particularly important to have a graphical understanding of the…

This paper addresses the subject of the semiosis process in the transactions between teachers and students about the knowledge at stake in science education. We present a conceptualisation of these transactions as a joint action between students and teachers. This conceptualisation enables us to understand the semiosis process as it unfolds during…

Learning management systems (LMSs) are ubiquitous in higher education, yet few studies have examined changes in student engagement online with year level. Using data mining of LMSs, we examined the frequency and timing with which first, second, and third year science students accessed the various LMS resources. We compared online access with both…
