The aim of this study was to identify, classify and describe different types of vernacular misconceptions assessed with the items used in a study named "Laboratory of Thinking," Diagnosis of Science Education in Poland. We provide an outline of contemporary conceptual change theories and establish a typology of misconceptions where it…

The four representative models that define oxidation-reduction reactions are often used differently in different situations or contexts in chemistry textbooks. Although integrated models have been suggested to overcome the confusion caused by this, they have not been successful. We therefore aim to interpret the causes for difficulties in the…

This study aimed to ascertain misconceptions of students about basic physical concepts in the "Force and Motion" unit of secondary school seventh class curriculum, to eliminate the misconceptions with created argument environment and traditional approaches after evaluated, and categorize these misconceptions in an ontological sense.…

This study involved the development of a two-tier diagnostic instrument to assess Thai high school students' understanding of acid-base chemistry. The acid-base diagnostic test (ABDT) comprising 18 items was administered to 55 Grade 11 students in a science and mathematics programme during the second semester of the 2008 academic year. Analysis of…

Within the historical context of the development of chemistry, Avogadro's hypothesis represents a fundamental concept: It allowed Avogadro to explain Gay-Lussac's law of combining volumes and it allowed Cannizzaro to establish a more accurate set of atomic mass values. If students are going to understand the concept of relative atomic masses and…

Differentiates between chemical nomenclature and the common ways that substances are named and described. Students should learn the chemical nomenclature so that they will be more observant and objective. Cites examples of student misconceptions based upon their own imagination and logic. (TW)

This study examined students' alternative conceptions of reptiles and amphibians and the extent to which these conceptions remain intact through the elementary (grades 4 and 6), junior, and senior high school years.
