    The aim of this dissertation study is to analyze how leadership emerges in a school-based makerspace, and analyze the ways in which emergent leadership mediates student-led making activities. The study also aims to investigate how teachers can support productive leadership during student-led collaboration. In the study, leadership is defined as a reciprocal social process that develops in students’ interactions. I argue that school-based makerspaces provide an important platform for the development of students’ emergent leadership. © ISLS.

    The design of instructional material affects learning from it. Abstraction, or limiting details and presenting difficult concepts by linking them with familiar objects, can limit the burden to the working memory and make learning easier. The presence of visualizations and the level to which students can interact with them and modify them also referred to as engagement, can promote information processing. This thesis presents the results of a study using a 2x3 experimental design with abstraction level (high abstraction, low abstraction) and engagement level (no viewing, viewing, presenting) as the factors. The study consisted of two experiments with different topics: hash tables and multidimensional arrays. We analyzed the effect of these factors on instructional efficiency and learning gain, accounting for prior knowledge, and prior cognitive load. We observed that high abstraction conditions limited study cognitive load for all participants, but were particularly beneficial for participants with some prior knowledge on the topic they studied. We also observed that higher engagement levels benefit participants with no prior knowledge on the topic they studied, but not necessarily participants with some prior knowledge. Low cognitive load in the pre-test phase makes studying easier regardless of the instructional material, as does knowledge on the topic being studied. Our results indicate that the abstractions and engagement with learning materials need to be designed with the students and their knowledge levels in mind. However, further research is needed to assess the components in different abstraction levels that affect learning outcomes and why and how cognitive load in the pre-test phase affects cognitive load throughout studying and testing.

    The effect of pre-service physics teachers’ prior knowledge of the subject on their roles and intensity in the online discussions is studied. Network analysis of initial knowledge and social network analysis of discussion reveal that both have characteristic structural features which are typical for each student. These features, however, are not correlated. Results show conclusively that structure and extension of student’s initial knowledge cannot explain activity and role in online discussions. © ISLS.

    The authors studied primary school students’ experiences of using an electronic portfolio in their craft education over four years. A stimulated recall interview was applied to collect user experiences and qualitative content analysis to analyse the collected data. The results indicate that the electronic portfolio was experienced as a multipurpose tool to support learning. It makes the learning process visible and in that way helps focus on and improves the quality of learning. © ISLS.
