||This research is a descriptive qualitative research. The data of the research are the performances in the frame of Systemic Functional Linguistics such as complexity of clause and groups, technicality, nominalization, lexical density, cohesion, and text structure. The sources of data are bedtime stories entitled “The Boy who Cried: ‘Wolf!’” written by Mary Graham Bonner and “Pinocchio” written by Carlo Collodi. This research is aimed at describing the readability level of the two bedtime stories that is analyzed by examining the complexity of clause and groups, technicality and nominalization, lexical density, cohesion and text structure. This research is conducted through Systemic Functional Linguistics approach. The data are taken by using purposive sampling method.
The research was conducted by analysing the sources of data based on the complexity of clause and groups, technicality and nominalization, lexical density, cohesion and text structure. Then the data descriptions are interpreted. The interpretation of the data is used a guide to determine the readability level of the texts.
The result of the analysis shows that both texts are dominated by complex clauses, simplex nominal, simplex verbal, and simplex adverbial groups, employ less technicalities and nominalization, have low lexical density, have logical cohesive relation and use narrative which belongs to story genre. These factors indicate that both texts have high readability level. The comparison of the two bedtime stories shows that text I has higher readability level than text II.
In conclusion, having written the thesis, it is recommended for anyone who wants to write good bedtime stories for and the students who are interested in SFL to concern more about the aspects of readability, for the readers especially parents to be more selective in picking reading materials for their children.
