Infants and toddlers experience the world in interaction with others. Likewise, social interactions are important in learning about math--concepts of number ("one," "two," "three"), space ("on top," "upside-down," "round"), and magnitude ("more," "big,"…

Gestures and other bodily movements are frequently used as instructional strategies in second language classrooms. Research has demonstrated that gestures are an effective strategy to improve L2 vocabulary recall. However, previous studies have only used vocabulary items that are known to participants in their native languages. Additionally,…

Learning a second language (L2) is not merely mastering an additional linguistic system, but rather learning a new way of conceptualizing the world. Grammatical development does not always align simultaneously with conceptual development in L2. That explains why L2 learners may produce sentences that are grammatically correct, but pragmatically…

The teaching and learning of mathematics in South Africa are conducted through the authorised Language of Learning and Teaching (LoLT). South Africa has eleven official languages, and English is a Language of Learning and Teaching (LoLT) from the Intermediate and Further Education and Training (FET) Phase. This study explores teachers' views on…

Background: IsiXhosa students enrolled for the BEd Foundation Phase qualification at a university in South Africa failed their first year in identified at-risk subjects, namely Mathematics in Education, Language in Education and Computer Literacy. The students stated the reasons for failure as not understanding the concepts and terms of the…

In this study, we explore how cross-linguistic differences can contribute to children's scientific thinking. We compared first and third grade Chinese students' pre-instructional ideas of the earth expressed in clinical interviews with that of their English-speaking and Greek-speaking counterparts (as recorded in the literature). Inspired by a…

To what degree can multilingual students profit from bilingual teaching approaches, even when they lack experience in the academic or technical register in their home languages? This study explores this research question in a mixed methods design for a German/Turkish bilingual intervention aimed at fostering conceptual understanding of fractions…

Education for multilingual Physics students in South Africa still has a monolingual bias despite such pedagogy being repeatedly identified as the key factor in students' academic underachievement in the subject. The paper reports on the pivotal role language plays in the comprehension and subsequent academic performance of students in science…

This study applies the Mathematics Acquisition Framework (MAF) (Bossé, Ringler, Bayaga, Fountain, & Young, 2018) to investigate fifth- through seventh-grade students' comprehension of fractions and decimals and examines how students build understanding of mathematical principles and concepts regarding fractions and decimals. Based on case…

The dissertation investigates the effect of a concept-based approach to teaching the Chinese temporal system to English-speaking university learners at the elementary level. The pedagogical framework, Systematic-Theoretical Instruction (STI), adopted in this study was proposed by Piotr Gal'perin and originated from Vygotsky's…
