In this review article, we discuss the construct of second language (L2) comprehensibility, which refers to listeners' judgments of ease or difficulty in understanding L2 speech. We first briefly describe intelligibility and comprehensibility, two measures that capture listener understanding of L2 speech. We then present evidence that supports the…

Based on cognitive load theory, this paper reports on two experiments investigating the variability effect that occurs when learners' exposure to highly variable tasks results in superior test performance. It was hypothesised that the effect was more likely to occur using high rather than low levels of guidance and testing more knowledgeable than…

A 2 (learning strategies: diagram vs. summary) × 2 (levels of expertise: low vs. high) experiment was conducted to compare the effectiveness of using diagrams to writing summaries for students given biological information to learn and who possessed different levels of expertise in that topic area. A main effect of learning strategy used on number…

One crucial skill to master by university students related to academic writing activity is paraphrasing skill. However, in Indonesian context, the university students still find paraphrasing challenging. Therefore, this study is intended to explore the use of read, reread, list, compose (RRLC) strategy to enhace the students' paraphrasing skill in…

Mastery goal structures, which communicate value for developing deeper understanding, are an important classroom support for student motivation and engagement, especially in the context of science learning aligned with the Next Generation Science Standards. Prior research has identified key dimensions of goal structures, but a more nuanced…

In this article the authors overview how the recently revised (version 9) Australian Curriculum (Australian Curriculum Assessment and Reporting Authority, 2022) and student difficulties with fractions relate to five developmental Fraction Schemes developed from multiple research projects in the literature. The article shares research findings from…

Literature has established that some learners encountered difficulties solving first order ordinary differential equations (ODEs). The use of error analysis in teaching ODEs is believed to make essential contribution towards calculus knowledge development. This paper therefore focuses on analyzing pre-service teachers' (PSTs) errors and…

Strategies mathematics teachers use can unintentionally have an adverse impact on student anxiety in the classroom. The purpose of the Action Research study was to investigate and strengthen strategies that mathematics teachers use to reduce student anxiety. Participants and data collected in Cycle 1 consisted of interviews and a focus group with…

Many children and adults have difficulty gaining a comprehensive understanding of rational numbers. Although fractions are taught before decimals and percentages in many countries, including the USA, a number of researchers have argued that decimals are easier to learn than fractions and therefore teaching them first might mitigate children's…

English language learners are increasingly entering classrooms using student-centered instruction that places a greater emphasis on spoken language. While active learning is beneficial for a range of student outcomes, these practices force language learners to carry a heavy cognitive load in a complex and challenging environment. This experiment…

Purpose: Previous studies have mainly discussed the impact of student engagement on different facets of academic performance. Research on the approaches to promote student engagement in a classroom setting (i.e., micro-level practices) is relatively sparse. This paper provides a framework for enhancing student engagement in a university…

Computational thinking requires high cognitive load as students work to manage multiple tasks in their problem-solving environment. Through research in K-2 classrooms on computational thinking, we noticed that students lack the representational fluency needed to move from one form to another--such as moving from physical to more abstract…

This study aims to investigate pre-service teachers' integration of technology and how the integration of technology influences the level of cognitive demands of the mathematics tasks in their mathematics technology activities. The purpose of this study was to investigate the various levels of cognitive demands of mathematical tasks created or…

Due to their abstract nature, representation of mathematical concepts through different registers favors their understanding. In the case of ''sequences and regularities'', it becomes propitious the exploration of different registers of representation in the institution of topics, such as term, order, formation law, and generating expression.…

Purpose: The present study examined the effect of Directed Activity Related to Texts (DARTs) and gender on student achievement in qualitative analysis in chemistry. It focused on the qualitative analysis component of the Chemistry course, which for students has been perceived as being the most difficult aspect of their mastery of the subject.…
