Pollock, David W.; Truong, Giovanna T.; Bonjour, Jessica L.; Frost, John A. – Journal of Chemical Education, 2018
Solubility is frequently introduced at the high school and introductory college levels through the symbolic domain using net ionic equations and solubility product constants. Students may become proficient with spectator ion cancellation and skilled with algorithmic mathematical applications of solubility without obtaining a deeper understanding…

Gültepe, Nejla – Educational Sciences: Theory and Practice, 2016
Graphing subjects in chemistry has been used to provide alternatives to verbal and algorithmic descriptions of a subject by handing students another way of improving their manipulation of concepts. Teachers should therefore know the level of students' graphing skills. Studies have identified that students have difficulty making connections with…

Mavhunga, Elizabeth; Rollnick, Marissa – Research in Science Education, 2016
In science education, learner-centred classroom practices are widely accepted as desirable and are associated with responsive and reformed kinds of teacher beliefs. They are further associated with high-quality Pedagogical Content Knowledge (PCK). Topic-Specific Pedagogical Content Knowledge (TSPCK), a version of PCK defined at topic level, is…

Bellocchi, Alberto; King, Donna T.; Ritchie, Stephen M. – International Journal of Science Education, 2016
There is on-going international interest in the relationships between assessment instruments, students' understanding of science concepts and context-based curriculum approaches. This study extends earlier research showing that students can develop connections between contexts and concepts--called "fluid transitions"--when studying…

Stott, Angela; Hattingh, Annemarie – Educational Technology & Society, 2015
The paper presents a case study of the use of conceptual tutoring software to promote deep learning of the scientific concept of density among 50 final year pre-service student teachers in a natural sciences course in a South African university. Individually-paced electronic tutoring is potentially an effective way of meeting the students' varied…

Adadan, Emine; Trundle, Kathy Cabe; Irving, Karen E. – Journal of Research in Science Teaching, 2010
This study investigated the conceptual pathways of 19 Grade 11 introductory chemistry students (age 16-17) as they participated in a multirepresentational instruction on the particulate nature of matter (PNM). This study was grounded in contemporary conceptual change theory, in particular, research on students' conceptual pathways that focuses on…
