One of teaching materials which can be enhance critical thinking skill students in chemical equilibrium is student worksheet based on guided inquiry. Student worksheet was created by using guided inquiry stages. It consisted of orientation, exploration, concept formation, application, and closing. It was also designed with the lesson study approach through three stages, namely plan, do and see.…
The research has been done with development of constructivism-based Student Worksheets (SWS) on amine material. The background of this research is the material related to the comparison between organic substances with substances of nomenclature, basicity, reactions of substitution and elimination. In addition, there are no SWS in learning that are based on learning models, so constructivism-bas…
The Office Technical Implementation Unit (UPTD) as an extension of the education office has a role as a coach for schools in the sub-district area. Inter-line coordination is needed in the development of education to achieve national education goals. This study aims to determine the role of the UPTD Education in the implementation of an education service information system in Minas sub-district…

This type of research is research development (research and development) with development process refers t…
The purpose of this study is to: (1) develop an Order Multiple Choice (OMC) instrument based on the Attribute Hierarchy Method (AHM) for the diagnosis of acid-base learning difficulties, (2) determine the characteristics of the instrument, and (3) create a diagnostic profile of individual student. This study uses the development Borg & Gall model. Preliminary study produces one of the difficult…
Teachers as educators rule in creating generations of knowledgeable and ethical people. Today’s education must be directed at increasing the competitiveness of the nation to be able to compete in global competition. A school-based teacher community was established in order to overcome weaknesses in the use of learning methods and conventional training and / or training models that are less st…
This study aims to develop of interactive learning media based on Autoplay Media Studio 8 on the colloid subject to improve the creative thinking skills of high school students, find out the validity and effectiveness of the media and find out the categories of increasing students' creative thinking skills. This study used Research and Development (R & D) method which refers to the Borg and Gal…
Learning process will have a good quality if there is collaboration between the ability of professional educators and qualified teaching materials. In this study, efforts were made to develop a teaching material which was a chemical learning module with chemical equilibrium materials through lesson study. Lesson study is carried out in three stages, namely plan, do and see. The development of t…
