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.

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

This study aims to produce the Practical KIT along with its devices that are effectively used as learning media to train students SPS on the sub material of the Reaction Rate Law. The method used in this study is Research and Development design. The research instrument used consisted of a sheet of pre-test and post-test. Data analysis was carried out in descriptive quantitative to determine the effectiveness of Practical KIT along with the devices developed. The media is said to be effective if it meets 2 requirements, namely the percentage of classical completeness <85% and N-gain value <0.3. The developed media has been declared effective as indicated by the increase in the value of cognitive learning outcomes in the "Medium" and "High" categories with 100% classical completeness, an increase in the value of science process skills of students after using the Practical KIT media. "With classical completeness reaching 91.67%.

Abstract

Abstract. The aims of this study to identify  the profile of students’  conseptions and misconceptions on the concept of reaction rate using a four-tier multiple choice diagnostic test instrument reported in the form of misconception profiles consisting of students' conceptions, students' misconceptions and the causes of misconceptions experienced by students. Based on the results of the study shown (1) the students’ conception profile is as much as 78% understand the concept, 21% misconceptions and 1% do not understand the concept, (2) the profile of student’s misconceptions in each sub-material that misconceptions on sub-material of concentration 16%, temperature 19%, surface area 41% and catalyst 24% and as many as 1 student (3%) including the high misconception category, 22 students (67%) included in the medium misconception category and 10 students (30%) were in the low misconception category. Students’ misconceptions vary in different causes such as; associative thinking 59%, preconceptions 25%, incomplete resoning 13%, humanistic thinking 2% and incorrect intuition 1% .  Keywords: four-tier multiple choice, misconception, reaction rate
