This research was conducted to investigate the effects of different techniques in Turkish language activities on language development of children aged 48-60 months. The research is an "experimental" study based on the "pretest-posttest and experiment-control group". The working group constitutes a total of 40 children, 20 children in the experimental group and 20 children in the control group, who attend the kindergarten in Bursa in Nilüfer district in 2016-2017 academic year. Denver II Developmental Screening Test was used as data collection tool in the study. While preparing language activities using different techniques, the attainments and indicators for the language development of the children in the Ministry of Education Preschool Education Program have been investigated. Language (Turkish) activities prepared by using 10 different techniques are used to reach determined attainments and indicators. It was seen that there was a significant difference between the mean scores of the experimental group pre-test-posttest. No significant difference was found between the mean scores between the pre-test and post-test of the control group. There was also a statistically significant difference between the experimental and control group posttest scores in favor of the experimental group. As a result of the study, the presentation of language (Turkish) activities to children with different techniques has been achieved as a positive influence on children's language development. Teachers can advise parents to prepare language activities that they can use in their family participation activities and do with their children. Families can make activities such as reading, chatting, drawing stories, drawing puppets, and puppet chatting in their homes.
