Science teachers communicate curricula goals to their students, prepare teaching situations and lead their students through them in order to learn science. The purpose of this study was to identify the beliefs of teachers about teaching and learning, specifically, what the teachers focus on, how they comprehend knowledge and their role in the process of learning since they can promote or hold back development of scientific literacy. Q methodology was used to investigate the beliefs of 65 science teachers by having them rank and sort a series of 51 statements. Factor analysis was used to identify identical patterns. The analysis showed that the teachers held four types of dominant beliefs about the effectiveness of science instruction and some common feature which have potential to influence educational process. Teachers concentrate on covering the content even if they declare the importance of personal construction, feel responsible for students’ learning and its outcomes. Despite stressing the activity of the students, the teachers did not emphasize particular science process skills and scaffolding process. The findings of the study suggest that systematic trainings focused on the nature of science and the scaffolding process would be beneficial for teachers in all identified factors.

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.

Opisano realizację projektu z chemii, którego głównym tematem były „Chemiczne pokazy - Harry Potter”. Uczenie się oparte na projekcie należy do skomplikowanych metod nauczania, gdzie na pożądany efekt może mieć wpływ wiele czynników, np. postawy studentów, ogólna opinia studentów i odczucia dotyczące metody. Celem badaczy było zrozumienie i ocena czynników występujących w realizowanym projekcie. Analizowane czynniki i schematy zachowań mogą stanowić dobry punkt wyjścia dla nauczycieli w planowaniu projektów. W celu zrozumienia reakcji studentów badacze wykorzystali Q-metodologię identyfikacji różnych grup behawioralnych uczestników na podstawie ich prawdziwych opinii. W prezentowanych badaniach naukowcy analizują odpowiedzi 26 studentów. W rezultacie zaobserwowano 6 przykładów zachowań, z którymi nauczyciele mogą spotkać się w trakcie realizacji nauczania opartego na projekcie. Przedstawiona klasyfikacja jest zgodna z innymi, wcześniej opisanymi rodzajami zachowań studentów, np. postawy „przyjemnych niespodzianek” i „rozczarowujących niespodzianek”. Jednak pojawiły się inne, dodatkowe rodzaje typów zachowań, np. studenci zorientowani i koncentrujący się na wiedzy teoretycznej, studenci z bardzo silną potrzebą przywództwa i studenci potrzebujący kilku systemów oceny. Przedstawione wyniki mogą zapewnić nauczycielom szerszy pogląd na przygotowywanie i przewidywanie przebiegu planowanych projektów.

The evaluation in technical invention is important because it tests functionality of the intervention and it forms an overall point of view of a user. This study aims to introduce an approach for collecting user expectations with Q methodology in Safe Private Home for Elderly Persons (CARE), which is a new development in ambient assisted living. CARE is a sophisticated fall detection system used in elderly homes to monitor elderly people and the staff. Expectations of elderly people and the staff were collected with Q sorting. Requirements of examined groups were explored successfully on the basis of the sorting and the differences in their opinions were appointed.
