English student’s issue on constructing tree diagram sentences

This research aims to identify the key difficulties students face and develop strategies to enhance their understanding of tree diagrams. The purpose of this research is to identify the specific difficulties students encounter when understanding and constructing tree diagrams and to develop recommendations for improving teaching practices based on the analysis results. The researcher focuses on the discussion at the class to obtain qualitative insights into students’ experiences and challenges in constructing the tree diagram, gather the data on student’s answers on the test, and assess the accuracy of students' tree diagrams and identify common errors from collected student work samples. The results of this study revealed that English language students make a range of errors when constructing and interpreting syntactic tree diagrams. These errors were classified into five main categories: hierarchical misplacement, grammatical mislabeling, incorrect phrase segmentation, visual representation issues, and task completion problems.
