Abstract

This study aims to describe the use of vee diagrams in an effort to increase motivation and learning achievement in Chemistry class XI.A.1 Sukomoro 1 Senior High School in the material of Salt Hydrolysis. This research is a classroom action research (CAR) which is carried out in two cycles, each cycle consisting of the stages of planning, implementation, observation and reflection. The research is a quasi experiment with a quantitative approach. The research design is Postest-Only Control Design. The object of the study was all students of class XI.IPA.1 of Senior High School Sukomoro in the 2015/2016 school year. Data collection techniques use test methods, and observation methods. The results showed that chemical learning using vee diagrams can increase motivation and learning achievement of Chemistry students in class XI.IPA.1 in Salt Hydrolysis material. In cycle 1 the average cognitive value of 71.05 becomes 80 in cycle 2, learning Chemistry using vee diagrams can be carried out well and can improve student learning motivation especially students gain real experience in everyday life.

Abstract

Classroom action research has been carried out in the XII MIA 3 chemistry subjects at SMAN 1 Gurah Kediri Regency with a total of 37 students consist of 11 male students and 26 female students. This research used a storytelling learning method with two cycles. The results showed a significant increase where the average formative value of students in cycle 1 was 53 to 79 in cycle 2. The observation result of the percentage students interest in learning. In the first cycle, reached 35% and increased to 44% in the second cycle. The observation result of the percentage of students attention listening to learning in the first cycle reached 52% and increased to 61%. Similarly, the level of active students participation in the first cycle reached 28% and increased to 45%. These results indicate the learning process using storytelling methods can increase the students interest and think as a whole.

Abstract

Learning materials have been developed which then conducted the study and validation to the expert lecturers and then tested to the students to find out the validity of the feasibility of learning materials in the field of Industrial Chemistry as one of the supporting subjects of Ecopreneurship in Chemistry Department. From the data obtained can be concluded that learning materials in the form of Lesson Plan, Worksheet, and Instrument Rating get very good criteria. These criteria are obtained based on theoretical feasibility and empirical feasibility. Based on these results, learning tools developed can be used as learning tools for Industrial Chemistry courses to support ecopreneurship.

Abstract

Learning can not only be done in the classroom with direct face-to-face activities but can now be done with the help of IT, for example with learned learning. Although learning with vi-learn or e-learn cannot indeed replace overall face-to-face learning in the classroom. The world of education cannot be separated from technological advances such as this study because sometimes in carrying out classroom learning there are obstacles that cannot be avoided. These obstacles can be administrative in nature such as national holidays which coincide with the schedule of courses and cannot be replaced on another day due to limited space and insufficient time. In this study, learning tools for the English for TEP-based learning program have been developed to learn the verbal communication skills of students majoring in chemistry. From the data from the validation results, it can be concluded that learning devices consisting of enrichment modules and worksheets are feasible to be used in learning lessons. Likewise, from the response data, students showed a positive response from students in using enrichment modules and worksheets.
