dc.description.abstract | The agroecosystem plays an important role in the national economy. However, the role of
the agroecosystem in education in the form of teaching and learning has not been used optimally.
It is less in providing opportunities for students to develop their mindset based on their abilities
so that the students do not understand the potential requiring the surrounding area. Modification
of collaborative learning with the Brain-Based Learning (BBL LC) model makes the learning
appropriate for the 2013 curriculum. The purpose of the study is to obtain a valid, effective, and
practical model which is suitable for junior high school science learning in the agroecosystem
area. The research and development study used three out of four stages in the 4-D model. This
research was conducted at Junior High School 7 Jember. The data collection techniques were
filling out the validation sheet, interview, observation, test, and documentation. The data analysis
techniques include data analysis from the validation results, model analysis, and model
effectiveness analysis. The result showed that the percentage of product validation was 85.81%
or in a very valid category. While the average of N-gain learning outcomes that represent the
model effectiveness was 0.53 and the students' problem-solving skill questionnaires got 75.87%
or in a good category. The model practicality was from the teacher, and student response
questionnaires obtained 92.94% and 94%, which falls to a very practical category. | en_US |
