The global pandemic has forced many people to make significant changes in their work, personal lives, and everyday duties and activities. This metamorphosis has also significantly affected education systems. Implemented research activity in the learning process and emphasised the development of children’s cooperation have recently been limited and often unattainable because of learner isolation, prevailing home education, and different countries’ COVID-19 quarantine measures. Herein, we investigated and tested the 2020 European spring preparedness, commitment, and erudition of in-service and pre-service teachers and parents in remote education. We profiled the following three paradigm models of successful remote education; specific experience of in-service and pre-service chemistry teachers and the parents of school-age children. Here, we concentrated on sensitive identification of the most common problems, disadvantages, and risks. Prospective teacher training should concentrate more on remote education. It should help develop teachers’ didactic competencies and increase their motivation and willingness to participate in this mode of education.

This article is focused on finding out pupils’ preconceptions about heat, temperature and energy. As a research tool we used a didactic test with individual types of tasks about the concepts. A total of 122 respondents aged 12 to 14 participated in the research. The research sample consisted of two groups of pupils. One group consisted of pupils attending a school assigned for talented pupils, for simplicity they are referred as talented pupils. The second group consisted of pupils who do not attend this type of school, we marked them as “general population”. The number of respondents in the sample of talented pupils was 54. The number of respondents in the sample “general population” was 68 pupils. In the research we compared ideas about concepts heat, temperature and energy of talented pupils and pupils of the “general population”. We also compared talented pupils and pupils of the “general population” in solving of conceptual and algorithmic tasks in didactic test. We found out pupils of the age from 12 to 14 have misconceptions about the concepts. We also identified the misconceptions and the most common are also mentioned in this article.

Learning tasks are a great motivation tool in chemistry teaching, necessary in the exposure and fixation part of a teaching process, and also often used when diagnosing the depth and type of student knowledge. Our research analysed the relationship between the student assessment in chemistry and their success in solving memory, algorithmic and conceptual tasks at symbolic, submicroscopic and macroscopic levels. The testing focused on chemical equilibrium, because this topic is appropriate to design and test the tasks. The collected data was evaluated by one-factor ANOVA analysis. We expected that, in comparison to average and weak learners, the excellent ones should be significantly more successful in tackling all the types of tasks and at all levels. However, our findings indicate that this assumption is invalid in the case of conceptual tasks, i.e. the understanding the depth of chemical concepts does not always correlate with the student assessment.
