Science teachers seek to increase student learning within the area of science. Through the implementation of National Science Education Standards, teachers are provided insights into learning techniques, strategies, and other guidelines for effective learning instruction. Teachers agree science is a complex discipline, which can be seen in the achievement levels of many middle grade students. This study seeks to examine the use of concept mapping and its effects on the achievement levels of middle school aged students. This type of learning method could improve and facilitate meaningful learning and engage students in extended science discourse, as well as help students construct an understanding of concepts.
