"ABSTRACTHigher education level has such contribution to develop students' understanding and attitude toward environment. In order to do so, a strategy or approach which is applied through an effective teaching model to develop students' awareness on environment is urgently required. Free inquiry Model and Mind Mapping try to create scientific thinking to students and help them develop critical, creative and innovative thinking in order to arise some ideas about the solution for environment problems. CAR is used as the design of the research with aims at finding out more creative and more innovative ways of learning, enhancing learning motivation, seeking the solution of environment problems and to relate the issue with real condition. The research conducted in Biology Study program, Faculty of Teachers Training and Educational Sciences, Pakuan University, 2013-2014 academic year involved the third semester students from class A. Two cycles were conducted during the research and two actions were dealt for each cycle. The findings show that there is an improvement in terms of enthusiasm from 73% in cycle 1 into 84 % in cycle 2. The average score regarding students' understanding about environment pollution is increasingly improved from 69,11 in cycle 1 to 76,56 in cycle 2. It also happens to the students' mastery learning which develops from 66,67% in cycle 1 into 83,33% in cycle 2. Students' ability in solving environment problems in cycle 1 which achieved 69,74 in terms ofd average score and 63,33 % in the area of mastery learning improves in cycle 2 becoming 77,69 and 86,67%."

"ABSTRACTThis study is classified as Classroom Action Research (CAR) which aims to improve the learning process and improve good learning outcomes in students in improving their ability to solve environmental problems in junior high school students. This study was conducted in state junior high school 2, Bogor City. The sample taken was 34 people in VIIG class, consisting of 1 teacher as a model and 2 collaborators. The study was conducted in two cycles, each cycle consisting of four main activities, namely planning, implementation, observation and reflection. This research applies the learning model of incuri and uses audio visual media. The first cycle of the value of problem solving ability is still low with an average of 75.18 with a completeness of 70%. In the second cycle there was a change in the grouping of learning according to the results of reflection in cycle 1, namely the number of groups into 9 groups. In the learning process each student gets an award by using a star board so that it can increase students' motivation in learning. Learning in cycles 1 and 2 is conducted experimentally, experiments are carried out outside the classroom and it can reduce student saturation, while in cycle 2 the second meeting is conducted in biology laboratories and seating positions remain U-shaped. In cycles 1 and 2 before students carry out experiments given film shows related to environmental pollution material and this is very helpful for students and students' enthusiasm increases high. The study was completed at the end of cycle 2 because it had reached grades an average of 82.35 with a high category with 100% completeness. And the results of processing and analysis can be concluded that learning with inquiry models and audio-visual media can increase the ability to solve environmental problems in WIG class 2 students in Bogor City Middle School 2."
