Abstract


The purpose of this study is to analyze and determine the effectiveness
of the application of direct learning models to improve learning
outcomes in chemistry subject to oxidation-reduction rea ction s. This
research was conducted at Ensino Secundário Geral Publico 99 Atauro
Timor Leste. The subjects in this study were students of grade 12
Natural Science. The tools used in this study were learning outcome
tests, learning sheet, lesion plan, Learning Outcomes Test. The
instrument was the Learning Management Observation Sheet, THB,
Question Grid, and student responses. Using observation, test, and
questionnaire techniques approach to get the data. Data management
in this study was carried out using descriptive analysis techniques. The
research results show that the resulting learning tools are proven to be
effective and good, and teachers can manage to learn well and on time
and all TPK are prepared thoroughly. Meanwhile, mastery learning for
THB was 0.37 or 37% with an increase in the proportion of students'
correct answers from an average of 0.43 to 0.80. After the teacher
applied the direct learning model, 100% of students said they were
happy with the components and were interested in participating in
teaching and learning activities, 80.95% of students said the language
used was quite easy to understand and 19.05% said it was easy to
understand, and 26.19% said it was quite clear and 73.81% said it wa s
clear.
