Abstract in English:

There is agreement in research about the need to find better ways of teaching chemistry to enhance students’ understanding. This thesis aims to contribute to the understanding of how we better support teaching and learning of undergraduate chemistry to make it meaningful and intelligible for students from the outset. The thesis is concerned with examining the interactions between student, specific content and teacher in the undergraduate chemistry classroom; that is, the processes making up the three relations of the didactic triangle. The data consists of observations of students and tutors during problem-solving activities in an introductory chemistry course and interviews with graduate students.

Systematic analyses of the different interactions between the student, the chemistry content, and the tutor are made using the analytical tool of practical epistemology analysis. The main findings of the thesis include detailed insights into how undergraduate chemistry students deal with newly encountered content together with didactic models and concrete suggestions for improved teaching and for supporting continuity and progression in the undergraduate chemistry classroom. Specifically, I show how students deal with the chemistry content through a complex interaction of knowledge, experiences, and purposes on different levels invoked by both students and tutors as they interact with each other. Whether these interactions have a positive or negative effect on students’ learning depends on the nature of knowledge, experiences and purposes that were invoked. Moreover, the tutor sometimes invoked other purposes than the ones related to the task at hand for connecting the activity to the subject matter in general. These purposes were not always made continuous with the activity which resulting in confusion among students. The results from these analyses were used for producing hypotheses and models that could support continuity and progression during the activity. The suggested models aim to make the content more manageable and meaningful to students, enabling connections to other experiences and purposes, and helping teachers and tutors to analyze and reflect on their teaching. Moreover, a purpose- and activity-based progression is suggested that gives attention to purposes in chemistry education other than providing explanations of chemical phenomena. The aim of this ‘progression in action’ is to engage students in activities were they can see the meaning of chemical concepts and ideas through their use to accomplish different chemical tasks. A general conclusion is that detailed knowledge about the processes of teaching and learning is important for providing adequate support to both undergraduate students and university teachers in the chemistry classroom.

Consequences of school grading systems on adolescent health: evidence from a Swedish school reform

A new study has examined a reform of the Swedish school system; a reform centred on the introduction of grades and increased use of testing, especially standardised national tests, in the 6th and 7th school year. The reform had an indirect effect on psychosomatic symptoms and life satisfaction for these pupils. The negative effects of the reform were generally stronger for girls.

Elever med erfarenhet av robotar kritiska till att ha dem i klassrummet

Digitaliseringen och samhällets snabba tekniska utveckling har bidragit till diskussioner och tester av pedagogiska robotar i skolan. Ny forskning från Göteborgs universitet visar att elever med erfarenhet av robotar som läser av och analyserar känslor är mer negativa till dem än elever som inte träffat på dessa robotar tidigare.

In the Principal’s Office: Clark Elementary’s Isley shares strategies to develop teachers

Virginia elementary-school principal Anna Isley says building leadership skills of teachers can help boost retention rates and improve student performance. Isley, who began her career as a teacher, says connecting with other teachers in her first year set her on the path to success.
