Abstract

Our contribution is devoted to study the ability of future chemistry teachers to organise pupils’ observation of chemical phenomena. In this article measuring of multi-level means is described, which should denote a readiness of probands to perform an observation during carrying out chemical experiment. It is based on the assumption that well-prepared observers are able to work actively and to propose alternative solutions, because of their deep understanding of a procedure. In next part of this article the results of a research carried out at Faculty of Natural Sciences in Bratislava are analysed. The research was also aimed to detect if students are prepared to perform chemical experiments without a risk that they will be confused by a procedure or different course of experiment as they had expected.

Abstract

The contribution describes the circumstances of the implementation of a chemistry project with the main theme “Chemical show - Harry Potter”. Project-based learning belongs between the complex teaching methods, where the desired effect can be influenced by many factors, eg student’s attitude, student’s overall opinion and feelings about the method. The motivation of the researchers was to understand and evaluate the factors present in the realised project. The analysed factors and behavioural schemes can provide a good starting point for the teachers at planning their projects. With the aim to understand the students’ reaction the researchers used Q-methodology to identify the different behavioural groups of participating students based on their real opinion. In the presented research the researchers analyse the response of totally 26 students. As a result totally 6 behavioural examples are presented that teachers can meet during implementation of project based learning. The presented categorization collaborates with other formerly publicised types of student’s behaviour, eg students of “pleasant surprises” and “disappointing surprises”. However, other additional types of behavioural types emerged eg students orienting and concentrating on the theoretical knowledge, students with very strong need for leading and students with the need of several assessment systems. The presented results can provide a wider view for the teachers in preparing and forecasting the flow of their projects and can help them to prepare the project.

Abstract

We investigated the difficulties and challenges for teachers in implementing microcomputer-based laboratory and inquiry-based education in basic schools, where pupils were unused to this type of education. To achieve this, we implemented lesson models with worksheets focused on chemical reactions, chemical decomposition and chemical synthesis; with demonstration experiments and video-recording of each lesson. We then utilized a qualitative research design to analyse the videos, concentrating on circumstances leading to increased and decreased pupil attention to the relevant events, and on subsequent student reflection. Experience gained from implementing our model lessons proved that achieving effective teacher-pupil communication was the greatest difficulty hindering teaching success. This particularly involved the formulation of predictions and conclusions which demands strong commitment, determination and skill from every teacher. A further difficulty was ensuring active pupil engagement in the discussion. We therefore instituted a set of teacher ‘working-rules’ to enhance success in this innovative form of education.
