PROMOTING COAL MINING ENGINEERING STUDENTS’ VOCABULARY USING SEMANTIC MAPPING

Abstract

The problem of this study was the effectiveness of promoting coal mining engineering students’ vocabulary using semantic mapping at Polytechnic of Akamigas Palembang. Therefore, the object of this study is to describe and analyze whether or not it is effective  to promote coal mining engineering students’ vocabulary using semantic mapping at Polytechnic of Akamigas Palembang.A pre-experimental method was used by the writer in this research. The design was pre-test post-test design. The population of the study was all the first semester of coal mining engineering students. The total number of the first semester students was 56 students.
