Abstract

This study aims to develop instructional materials for writing procedural texts based on Mandailing local wisdom for eleventh-grade students at Imelda Ritonga Health Vocational High School and to examine their feasibility, practicality, and effectiveness in Indonesian language learning. The study employed a Research and Development (R&D) approach using the ADDIE model, which consists of the stages of Analysis, Design, Development, Implementation, and Evaluation. Data were collected through observations, interviews, questionnaires, expert validation, and learning achievement tests. The research participants included a subject-matter expert, an instructional design expert, an Indonesian language teacher, and eleventh-grade students. The product developed was a procedural text writing module that integrates Mandailing local wisdom through the context of preparing the traditional food Itak Poul-Poul. The validation results indicated that the instructional materials were categorized as highly feasible, with an average score of 91.5%. The practicality test showed very positive responses from both teachers and students, with an average percentage of 92%. Furthermore, the effectiveness test revealed an improvement in students’ learning outcomes, as demonstrated by an increase in the average score from 68.40 on the pretest to 85.70 on the posttest. These findings indicate that the developed instructional materials can enhance students’ procedural text writing skills while introducing local cultural values. Therefore, the instructional materials are considered valid, practical, and effective, and they have the potential to support the preservation of local culture through education.

Abstract

This study aims to describe the development process, assess the feasibility, and determine the effectiveness of teaching materials for writing folklore integrated with the local wisdom of North Sumatra and supported by digital comic media for seventh-grade students at SMP Negeri 1 Pasaribu Tobing. The study employed the Research and Development (R&D) method using the ADDIE model, which consists of the stages of Analysis, Design, Development, Implementation, and Evaluation. The development process began with a needs analysis involving teachers and students, followed by the design phase, development of learning materials and digital comic media, expert validation, implementation, and product evaluation. The validation results indicated that the teaching materials were categorized as highly feasible, with material expert assessments ranging from 93.9% to 95.1%, design expert assessment at 94.8%, and Indonesian language teacher assessment at 95%. The trial results showed very positive student responses, reaching 91.6% in the small-group trial and 92.7% in the large-group trial. The effectiveness of the teaching materials was demonstrated by the improvement in students’ learning outcomes after using the developed product. In addition to enhancing students’ folklore writing skills, the teaching materials also promoted the values of North Sumatran local wisdom, such as Dalihan Na Tolu, marsiadapari, holong, mutual cooperation, responsibility, and respect for others. Therefore, the developed teaching materials were found to be highly feasible and effective for use in Indonesian language learning.
