The research on learning device development was conducted from January to July 2015. Method of the research used 4-D model (four D Models) that include four stages, such as define, design, develop, and disseminate (data presented in this article is in develop stage), topic and scope of Biology on Lesson Study-based development (Plan, Do, & See) used four Biology teachers who collaborated with the researcher. The devices were tested using one group pretest-posttest design at Senior High School of SMA N 1 Dimembe at the tenth grade, X/a. Learning devices of Syllabus, Instructional Implementation Design, and Worksheets were delivered to 3 experts as validator. Results: 1) Evaluation of the expert for Syllabus was excellent by 10 criteria of evaluation as follow: identity of the syllabus; developing standard of competence; developing basic competence, developing the main subject of learning material; developing learning activity; developing indicator formulation; evaluation; determining time allocation; determining learning source; and developing the characters. 2) Evaluation of the expert for Instructional Implementation Design (RPP) was excellent by 10 criteria as follow: RPP format, standard of competence, basic competence, and indicator of competence achievement; objective of learning; teaching material; time allocation; learning activity; learning strategy of Open Inquiry Integrated with NHT; language and writing; the use of RPP. 3) Evaluation of the expert for the Worksheets was excellent by 8 criteria as follow: identity, basic competence, and indicator of competence achievement; objective of learning; topic description; directions and working steps; questions; tools and materials; table of observation. Results of the research showed validity of learning devices was excellent for Syllabus, RPP, Worksheets, and learning results of 25 students along with their scores that have been achieved respectively; 8 students with qualified marks (3.60-4.00); 14 (3-3,59); 3 (2.00-2.99).
