The aim of this knowledge overview is to investigate several factors that contribute to the reading development of students in the lower grades in elementary school. We want, as future teachers, gain knowledge so we can provide a good education based on good conditions. Based on the aim, we have formulated a question that can help us to identify numerous considerable factors. Our question is “Which factors benefit the reading development for students in Swedish subjects in the lower grades in elementary school By a socio-cultural perspective?” We have used a systematic search process for various scientific sources on different databases to obtain essential information for this knowledge overview. The databases we chose to use during the process were SwePub and ERIC. We have chosen ten sources published between years 1999 and 2018 in order to find relevant facts. When we studied the selected sources, we were able to identify five different themes that everyone had a significant role in students’ reading development. The themes we focused on were; the climate in the classroom, the teacher’s role, student-active tasks, the structured conversation and reading at home. Our purpose of this overview has not been to find right, or wrongs and we have therefore been impartial when we examined the researchers’ different studies and their results. The studies showed that it is important that the environment in the classroom is a safe place where respect and consideration are shown for everyone’s differences and conditions. The teacher must be aware of every student’s individual needs and be able to structure the education and adjust tasks according to this. Support for the student’s reading development has also been shown to be beneficial both in the school environment and in the home environment. The students’ must also get the opportunity to take part of structured conversations. In cooperation and interaction with others learning is fulfilled. Reading at home together with others is also proven beneficial for students’ reading development. The result shows that there are various factors that matters and need to interact for a decent reading education that leads to a good reading development for the students.
