Diagnosing the Quality of High School Students' and Pre-Service Chemistry Teachers' Cognitive Structures in Organic Chemistry by Using Students' Generated Systemic Synthesis Questions
Peer reviewed Peer reviewed
Direct linkDirect link
Hrin, Tamara; Milenkovic, Dušica; Segedinac, Mirjana – Chemistry Education Research and Practice, 2018
The importance of well elaborated cognitive structures in a science knowledge domain has been noted in many studies. Therefore, the main aim of this particular study was to employ a new diagrammatic assessment approach, students' generated systemic synthesis questions (SSynQs), to evaluate and compare the quality of high school students' and…

Segedinac, M. T.; Horvat, S.; Rodic, D. D.; Roncevic, T. N.; Savic, G. – Chemistry Education Research and Practice, 2018
This paper proposes a novel application of knowledge space theory for identifying discrepancies between the knowledge structure that experts expect students to have and the real knowledge structure that students demonstrate on tests. The proposed approach combines two methods of constructing knowledge spaces. The expected knowledge space is…

Milanovic, Vesna D.; Trivic, Dragica D. – Chemistry Education Research and Practice, 2017
The aim of this research was to explore the effects of two approaches, designated as the historical and the contemporary one, on the level of students' understanding of the properties and the practical use of gases. Our research hypothesis was that the historical context of the discovery of gases and the study of their properties would deepen…

Kostic, V. Dj.; Jovanovic, V. P. Stankov; Sekulic, T. M.; Takaci, Dj. B. – Chemistry Education Research and Practice, 2016
Problem solving in the field of quantitative composition of solutions (QCS), expressed as mass share and molar concentration, is essential for chemistry students. Since successful chemistry education is based on different mathematical contents, it is important to be proficient in both mathematical and chemistry concepts as well as interconnections…

Translation of P = kT into a Pictorial External Representation by High School Seniors
Peer reviewed Peer reviewed
Direct linkDirect link
Matijaševic, Igor; Korolija, Jasminka N.; Mandic, Ljuba M. – Chemistry Education Research and Practice, 2016
This paper describes the results achieved by high school seniors on an item which involves translation of the equation P = kT into a corresponding pictorial external representation. The majority of students (the classes of 2011, 2012 and 2013) did not give the correct answer to the multiple choice part of the translation item. They chose pictorial…
