Investigating School-Guided Visits to an Aquarium: What Roles for Science Teachers?

The main goals of this study were to understand the different roles played by teachers and students during a school-guided tour to an aquarium and to analyse their different perspectives about the visit. The study focused on students’ and teachers’ behaviour during school-guided visits to an aquarium; students’ and teachers’ perspectives about this type of school visits; and the reasons provided by teachers to engage in a guided tour to a science museum. Direct observations of 39 guided tours were performed in order to describe the structure of the visit and the participants’ behaviour. A questionnaire was given to 145 teachers and 191 students after the visit, in order to describe their perspectives about the visit, and an online questionnaire was sent to a sample of 11 teachers, in order to understand their ideas about school visits to science museums. Data analysis showed that the guided visits, although well evaluated by both students and teachers, were mainly guide-directed and lecture-oriented, giving students and teachers very little choice and control over the learning agenda. Moreover, teachers showed a very passive role during the visit and reported limited plans for preparation and follow-up activities that would support the visit. Despite this scenario, the teachers who were questioned preferred guided visits to non-guided visits and recognized the potential of museums for learning. The possible role of teachers in establishing the necessary connection between guided tours and school science, and helping to bridge school curriculum, museum content, and student inquiries is discussed.

Promoting Science Outdoor Activities for Elementary School Children: Contributions from a research laboratory

The purposes of the study were to analyse the promotion of scientific literacy through practical research activities and to identify childrens conceptions about scientists and how they do science. Elementary school children were engaged in two scientific experiments in a marine biology research laboratory. A total of 136 students answered a questionnaire about their previous habits towards science and carried out the following actions: (1) a guided visit to the laboratory, (2) a brief presentation of the research theme, (3) the development of two experiments, and (4) a questionnaire about the experiments and science conceptions. The research methods included observation, document analysis, and content analysis of the answers to the questionnaires. Additionally, each visit was video recorded in order to design learning materials. The results revealed that most of the pupils were able to follow every stage of experimentation. However, some of them misinterpreted results and conclusions. One implication of the study is that this type of outdoor activity is extremely important to promote meaningful science learning in children, but more care should be taken in practical science activities so that children can overcome some common difficulties when performing scientific inquiry.
