Progressing from additive to multiplicative thinking is a key outcome of school mathematics, making ratios an essential topic of study in junior secondary. In this study, 15 Australian Year 8 students were administered a ratio test followed by semi-structured interviews to explore their conceptions of ratio prior to formal instruction. In this…

The use of social media continues to grow in presence and influence throughout society. Inevitably, the role of social media in schools has become an increasingly important field of research. This quantitative study analyzes survey data collected from rural elementary school teachers at a large school district in the Southeastern United States…

Metacognition is one of the key learning skills in the 21st century, with a strong potential to help students succeed in science learning. Until now, this metacognitive awareness is less empowered by lecturers in learning. This study aimed to analyze the problem-based learning (PBL) reading-questioning-answering (PBLRQA) model's effect on…

The purpose of the study is to identify the Sense of responsibility of science teachers towards the learning of their students from the perspective of the teachers themselves; the study has included three domains (cognitive, skillful, and emotional); and to demonstrate the differences in the level of responsibility among science teachers based on…

Learning progressions (LPs) are novel models for the development of assessments in science education, that often use a scale to categorize students' levels of reasoning. Pictorial representations are important in chemistry teaching and learning, and also in LPs, but the differences between pictorial and verbal items in chemistry LPs is unclear. In…

Purpose: Given that prior research has confirmed that students' mathematics values significantly affect their mathematics learning, understanding how students' values form and change, especially during different learning stages, is an important topic. Design/Approach/Methods: This study administered a questionnaire to investigate the values of…

The current study focuses on developing the learning progression of number sense for primary school students, and it applies a cognitive diagnostic model, the rule space model, to data analysis. The rule space model analysis firstly extracted nine cognitive attributes and their hierarchy model from the analysis of previous research and the…

The concept of variability is central to statistics. In this research report, we review mathematics education research on variability and, based on that review and on feedback from an expert panel, propose a learning progression (LP) for variability. The structure of the proposed LP consists of 5 levels of sophistication in understanding…
