Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; classroom assessment; formative assessment; summative assessment; assessment event; literacy event; writing discourse; literacy practice; assessment practice; feedback; writing instruction; lower secondary schoolThe present study aims to investigate instruction and assessment in Swedish during two writing units; a fairytale and a book review; in lower secondary school; year seven. The research questions that guide the study deal with aspects such as what subject content appears to be important in the classroom instruction; how this con-tent is highlighted; and what appears to be the purpose of the assessment. The an-swers to the research questions contribute in giving a description of the predomi-nant writing discourse and they provide a basis for an overall comparison of what is emphasized in instruction and in assessment respectively; thus shedding light on the alignment between classroom instruction and assessment. Data were collected from multiple sources: video and audio recordings of twen-ty lessons; material based “observiews” observations of the teacher while as-sessing students’ final texts aloud ; assessment rubrics; and the teacher’s lesson materials. The classroom practice is explored as a literacy practice; based on the idea that reading and writing are always situated within specific social practices; and as an assessment practice; based on the idea that classroom assessment is an important part of the classroom atmosphere and helps students to form concepts of them-selves as learners as well as of what is important to learn. In the data; literacy events and assessment events are analyzed through a framework of writing dis-courses. With the analytical focus on literacy events and assessment events; the study also contributes to the research field as to if and how these concepts are re-lated. The main findings suggest that there is an overall agreement between instruc-tion; formative assessment and summative assessment in the studied practice. However; a contradiction between tradition and change can be seen in assessment of texts. During the fairytale unit; a contradiction can be seen between a genre discourse and a creativity discourse. During the book review unit; a contradiction can be seen between a genre discourse and a skills discourse. Assessment events tend to occur in literacy events when important content comes up. Eleven assess-ment events have been identified according to the purpose they seem to have in relation to the subject contents and requested ways of knowing.; språkdidaktik;
