This research deals with a possible use of history of mathematics in mathematics education. In particular, history can be a fundamental element for the introduction of the concept of integral through a problem-centred and intuitive approach. Therefore, what follows is dedicated to the teaching of mathematics in the last years of secondary schools,…

Horvat, Saša A.; Rodic, Dušica D.; Roncevic, Tamara N.; Babic-Kekez, Snežana; Horvat, Bojana Trifunovic – International Baltic Symposium on Science and Technology Education, 2021
Mathematical calculations are an important part of chemistry. Those problems are difficult for students, especially if the task is set with a limiting reactant. The aim of this study was development of a Procedure for evaluation of cognitive complexity of the Stoichiometric Tasks with a Limiting Reactant. The procedure created included an…

Validation of Method for the Assessment of Cognitive Complexity of Chemical Technology Problem Tasks
Horvat, Saša A.; Rodic, Dušica D.; Roncevic, Tamara N.; Segedinac, Mirjana D. – International Baltic Symposium on Science and Technology Education, 2019
The aim of research was validation of a method for the assessment of cognitive complexity of chemical technology problem tasks. The method included an assessment of the difficulty of concepts and an assessment of their interactivity. As a research instrument for assessing performance, test of knowledge was used. Each task in the test was followed…

Shin, Youngjoon; Seo, Hae-Ae; Hong, Jun-Euy – International Baltic Symposium on Science and Technology Education, 2019
This research aimed to develop an assessment tool for students' Positive Experiences about Science (PES). A preliminary version of PSE was developed through literature review, consisting of academic emotion, self-concept, learning motivation, career aspiration, and attitude in science. A pilot test was conducted with 198 students and a main test…
