Formal science education is the last stage of acquiring scientific knowledge for most people. They rely on the knowledge acquired at school for the rest of their lives. Therefore, it is important that formal education changes students' colloquial knowledge into scientific knowledge and is correct. The study decided to test three situations. In the…

Students' perceptions of an activity involving visualization are important in assessing their learning of the task. In view of this, this study was developed with undergraduate students from different courses at a public Brazilian university. The research objective was to determine how three students, who are majoring in different courses…

Eponymous terms play an important role in STEM education. This research focuses on the current state of Mendeleev eponyms in the context of education and ethnocentrism, addressing their usage in various languages, their educational value, cases of questioned priority and copyright violation in Mendeleev major eponyms--periodic table and periodic…

The Lawson classroom test of scientific reasoning is a quite popular and widely used tool that measures the level and development of the student's scientific reasoning skills. In this contribution, the results of this test for the N=446 students of the Faculty of Science Palacký University Olomouc from the years 2018-2020 at the beginning of their…

Examining students' inclinations to use algorithms and rules to solve a task was a fruitful area of research in chemical education in the last four decades. This research aimed to examine whether students read the task request carefully, considering its meaningfulness, or they approach it mechanically, applying a set of algorithms by default. The…

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…

In the era of universal and compulsory education, in which attention is paid to the ability to think scientifically, there should be no room for unscientific views. However, unscientific theories often appear in the media, and they find numerous supporters. Therefore, it was decided to investigate which of the common beliefs about the…

The comparative analysis of different meanings of Chemistry is carried out, taking in account philosophical, didactic, psychological and socio-cultural aspects. The issue is discussed in terms of the concurrent existence of two different subsystems referred both to Science and Education which can be found in presentations of chemistry knowledge.…

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…

The aim of research was to verify the effectiveness of implementing the inquiry-based teaching (IBT) into the teaching process of chemistry in secondary school in the phase of revising and deepening the previous-year learning content. The results of the research confirmed a significant difference on the level of knowledge and skills between the…

It has been 150 years since D.I. Mendeleev formulated the Periodic law and expressed it visually in the form of a table of elements in 1869. As is clearly well known today, Mendeleev's ideas, confirmed by the discovery of the elements he predicted, turned out to be very promising indeed. However, Mendeleev was not the first, nor the only scientist…

The research was focused on the teacher's opinions about the key and critical points of the lower secondary chemistry curriculum in the Czech Republic. Through the interviews with 40 chemistry teachers from four Czech regions was gained information about what teachers named as critical topics and what as key topics in early chemistry school…
