This study aims to analyze and examine the effect of Goal Orientation and Learning Models on the learning outcomes of Chemical Bonds in SMA / MA. Goal Orientation or goal orientation is divided into two namely Mastery Goal Orientation or completeness orientation and Performance Goal Orientation or appearance orientation. The learning model applied is the Problem Based Learning and Discovery Lea…
The research that has been done is the research on the development of guided inquiry-based chemical solution buffer to improve students' creative thinking abilities and self-confidence. Research is motivated by the still limited teaching materials or learning tools that facilitate students in enriching experiences, building knowledge and activeness of students, and supporting students to formul…
The research that has been carried out is the development of LKPD (Student Work Sheet) based on PBL (Problem Based Learning) to improve critical thinking skills and learner independence of students in class X Chemistry Bond material in SMA / MA. This research is motivated by the condition of teaching materials contained in the field that have not facilitated students in improving critical think…
The research has been done is the effectiveness of application problem based learning (PBM) and inquiry models on communicative, independent characters and students learning outcomes on Thermochemistry materials. This research is motivated by the value of student learning outcomes on thermochemistry materials that are still relatively low, communication skills of students during the learning p…
Developing this assessment instrument should be done because the problem was found at State Senior High School 1 Ujungbatu and State Senior High School 2 Ujungbatu that the teachers in these schools have never made a question to measure creative thinking skills of students. Creative thinking skill plays an important role in achieving educational objectives, especially in understanding chemical …
Developing this assessment instrument should be done because the problem was found at State Senior High School Plus Riau Province and State Senior High School 14 Pekanbaru that the teachers in these schools have never made a question to measure creative thinking skills of students. Creative thinking skill plays an important role in achieving educational objectives, especially in understanding c…
The research that has been done is the development of problem based learning E-module learning media to improve student learning outcomes on the subject of electrolyte and non-electrolyte solutions. The research is motivated by the limitations of learning media used by teachers in the 21st century. Development of E-module media can be an alternative to developing learning media that can improve…
This research aims to design constructedly and develop e-module using the Kvisoft Flipbook Maker application on the subject of chemical equilibrium that is valid, practical and effective. This type of research is a Research And Development (R&D) and has been developed using the Plomp model with three stages, namely preliminary investigation, prototyping phase and assessment phase. The test subj…

The objectives of this study are: (1) to develop constructivism-based student worksheets on material of Carboxylic Acid and its derivates, (2) to acknowledge the feasibility of constructivism-based student worksheets on material of Carboxylic Acid and its derivates according to expert validators based on didactic aspects, constructs (presentation and linguistic aspects), technical, and characte…
This study aims to develop assessment test instruments to diagnose critical thinking skills in chemical equilibrium material, find out characteristics (validity, reliability, level of difficulty and differentiation), and classify school categories based on indicators of critical thinking. This study uses the Borg and Gall model development approach. The results showed that 30 chemical equilibr…
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…
