Sustainability is internationally often emphasized as an essential aim of higher education, but more as a principle than on the practical level. This is also obvious in the academic education of primary teachers in Finland. Therefore, it is a great challenge for Finnish teachers to include sustainability in their teaching and everyday life in schoo...

Knowledge of species, interest in nature, and nature experiences are the factors that best promote interest in and understanding of environmental issues, biodiversity and sustainable life. The aim of this study is to investigate how well student teachers identify common local species, their interest in and ideas about species identification, and th...

According to previous research, pupils and students regard genetics as a very difficult subject. They find it abstract, and the use of many concepts at several different levels in the same textbook makes it difficult for them to understand. Teaching methods and ways of working have been criticised as part of the problem. The aim of this study is to...

The media, as a source of information, is supposed to have a significant role in effecting people's environmental knowledge and attitudes. The purpose of this study was to find students' perceptions of environmental issues as presented in the media and how students in Finland, Lithuania and Sweden used these media sources in the matters related to...

Alarming trends in science in Nordic schools, indicating a diminishing interest among students, a lack of knowledge and competence among teachers as well as a decreasing amount of science in teacher education sparked this study of student teachers in Denmark, Finland and Sweden. This quantitative and qualitative study of teacher students’ views of...

According to recent research, the knowledge of species, interest in nature, and nature experiences arethe factors that best promote interest in and understanding of environmental issues and sustainable life style. However, during the past 20 years the knowledge of species has decreased alarmingly among pupils, but also among their teachers. The aim...

Students after graduating school must have both, knowledge and basic skills for ac-tive life-action, which includes their ability to evaluate their knowledge and skills for usabil-ity both in everyday life and in future. In this article knowledge of different problems within science education and its usability for future life, evaluated by the Latv...

The microturbellarian Microstomum lineare bears two pairs of glandulo-sensory organs, i.e. epidermal pigmented eyespots and ciliated pits. The ciliated pits are bottle-shaped grooves which open to the lateral margins of the worm. The walls of each pit consist mainly of two kinds of cells. The first, dominant cell type is placed postero-laterally al...

The ultrastructure of three types of sense receptors in the anterior end of Stenostomum leucops is described. Type I is characterized by abundant branching microvilli and ciliary rootlets but a lack of cilia. Type II possesses a short cilium with aberrant axonema. Type III has a cilium protruding from an invagination, a long rootlet and a collar of...

General body sensitivity to light is present in Stenostomum leucops, expressed as increased activity and locomotion of resting animals by exposure to light. The sensory structures involved have not been identified so far. The head of S. leucops bears sensory cells in the ciliary pits, along the epithelium and in connection to the brain lobes. Two t...
