This study aims to find out: (1) The effect of the application of the DLDPF model on improving TDBI writing proficiency; (2) Differences between student learning outcomes with the DLDPF model and without DLDPF; and (3) Student obstacles in the application of the DLDPF model. The design of this study is a pseudo-experiment with a non-equivalent comparison group design scheme. The researcher used a nonprobability sampling technique in the form of total sampling. The instruments used in this study are tests and questionnaires. The test instrument is in the form of an essay test with four aspects of assessment criteria (content, organization, grammar, and vocabulary). There are also document study instruments and semi-open questionnaires with the Likert Scale. The results of the study revealed the following findings. First, the results of the paired sample test showed a sig. (2-tailed) of 0.00 < 0.05 which means that there is a significant influence of the application of the DLDPF model on the improvement of TDBI writing proficiency. Second, the results of the independent sample t-test showed a sig. (2-tailed) of 0.00 < 0.05 which means that the application of the DLDPF model has a significant impact on improving TDBI writing proficiency. In addition, the experimental class has an N-gain score of 0.59 which means it has a moderate level of improvement. The control class has an N-gain score of 0.24 which means it has a low level of improvement. In other words, it shows that there is a difference between student learning outcomes with the DLDPF model and student learning outcomes with no DLDPF model. And third, respondents showed few obstacles in the application of the DLDPF model, including: (1) Most of the respondents (70.53%) did not experience linguistic barriers; and (2) Most respondents (70%) did not experience nonlinguistic barriers.

The maintenance of education must be tailored to the needs and interests of students so that they learn something that interests them. Therefore, today's educational systems focus educational objectives and processes on the child's factor and can foster freedom of interests and needs. This makes the Social Science subjects taught in primary school must be based on the needs and interests of the child about the environment in which he lives. Basically, the subject of Social Science must be taught with a full sense of responsibility to the student, because it is very closely related to the people and the environment where humans live and carry out the activities to meet their needs. This makes the role of the teacher not only as a teacher but also as a guide and at the same time as an administrator. The personal teacher as a unit also determines the learning result given. Therefore, the component of the teaching situation, the correct delivery method and the media used also determine the learning outcome.Thus it can be concluded, that learning will be successful when considering many interrelated teaching components. These components can be grouped into three main categories, namely: first, the teacher, second, the subject matter, and third, the student. The interaction between the three main components involves the means and objects, methods, media and setting up of the learning environment so that a learning situation is created that enables the achievement of a previously planned goal.
