Learning physics requires complex aspects of the students, not only the skill for achieving a task but also their beliefs of about their ability in overcoming the difficulties in achieving the purposed targets. In this case, students' self-efficacy takes an important role in determining their success to improve their learning achievement. This research aimed at improves students' self-efficacy and learning achievement with cooperative learning group investigation on statics fluid. A one group pre-test- post-test design was implemented to the sample of 75 students with three-time replications. This research was conducted at Senior High School 3 Singaraja-Bali in the odd semester of the academic year of 2017/2018. Research data were collected by using questionnaire, observation, and test. The N-Gain score and qualitative descriptive analysis were applied to analyze data. The results indicate that: (1) there is an increase in students' self-efficacy with a high N-Gain score, (2) there is an increase in students' learning achievement with a high N-Gain score and (3) the students' response is positive to the learning activity. The conclusion is that the implementation of cooperative learning model group investigation can facilitate students to improve their self-efficacy and learning achievement on learning physics, especially for statics fluid. © Published under licence by IOP Publishing Ltd.
