Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Hypothesis: Five weeks of 20 sessions of GL will improve the accuracy of word and nonword decoding skills in children with DLD from baseline to T2 and T3. The GL intervention group will perform higher number of accuratly decoded words and nonwords than the two control groups at T2, and at T3.
The second aim is to elucidate how the parents' language and reading skills, prevalence of language-related diagnoses, and socio-economic-status, and the children's self-reported self-esteem is related to their reading skills.
Hypothesis 1: Children with DLD who's parents show poor language and/or reading skills will perform lower on the word/nonword decoding tests.
Hypothesis 2: Children who show no significant improvement of word/nonword decoding skills will to a higher degree have parents with reading difficulties.
Hypothesis 3: Parents highest level of education will not be associated with the participating childrens language and reading skills.
Hypothesis 4: Results from the self-reported self-esteem will be lower than normdata from the test manual, and will not be associated with the children's language and reading skills.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
(II) Anamnestic interviews with the participants' parents aiming at collecting information about the child (diagnoses or developmental challenges); reading activities in the family; family aggregation of language-related diagnoses and problems in the parents and siblings, and highest level of education of each parent, as well as their current occupation.
(III) Language and reading tests of parents, same reading tests as in (I); and tests of nonword repetition, grammatical production of past tense; and sentence repetition.
(IV) Questionnaire to the schools covering type and dose of formal reading instruction, and who is providing this instruction (e.g., teacher or special teacher) and in what kind of context (individual, whole class, and/or in small groups of children).
The investigators will perform analysis of primary and secondary outcomes and influence of background factors in a mixed linear model with time- and groupinteraction effects. Background factors will be presented with relevant descriptive statistics, such as mean and standard deviations.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Usual schooling
Children with DLD who attend a special school for children with DLD. This children will have normal schooling as usual without playing any of the above computer games.
Usual schooling
No GL or Math computer games, only the usual schooling
Grapholearn group
Children with DLD who attend a special school for children with DLD. This group will play the computer game GL in school for 5 weeks, 20 sessions, 15-30 min per session. Supervised by a teacher.
Grapholearn
GL is a computer game based on the phonics-method (i.e., graphem-phoneme correspondence). It was developed at Jyväskylä University in Finland, in several languages, among others also for Swedish.
Math game group
Children with DLD who attend a special school for children with DLD. This group will play a computer game focusing on math in school for 5 weeks, 20 sessions, 15-30 min per session. Supervised by a teacher.
