The same number of students formed the control group.
The research sample of 108 students in 3 classes is obtained randomly from among students of Mathematics and Science Education Studies using a stratified random sampling technique.
26, Issue 2, 2015, 104-125 ABSTRACT: The aim of this research is identify the effectiveness of a multiple representation-based learning model, which builds a mental model within the concept of atomic structure.

These findings indicate that learning by multiple representations strategy could been alternative strategy in the teaching of chemistry to solve problems creatively, particularly concepts related to the phenomenon of sub-microscopic, macroscopic and symbolic. The results showed that (1) After learning by using multiple representations strategy, mental models abilities of students becomes higher, which is located at the level of intermediate-3 (2) Multiple representation strategies give a high influence to the improvement of the students’ mental models to the concept of atomic structure. This test is a test of creative problem solving to look at the ability of the student’s imagination. Mental models of the students was measured through tests in the form of an essay. The selected number of samples as many as two classes of students grade 10 and students involved in this study as 76 peoples. The samples in this study was conducted through random cluster sampling with the study subjects were taken from a high school student in Lampung Province. ABSTRACT Student’s mental models in this study was built through model-based learning with multiple representations.

Applying this computerbased strategy is highly recommended to guide students in understanding chemical concepts, especially the topics of orbitals and quantum numbers. The results showed that students in experimental class had significant conceptual changes compared to control class. Then, after implementing a learning exercise activity, the conceptual changes were analyzed using a post-test instrument. The students’ pre-existing concepts were analyzed using a pre-test instrument and explored further using in-depth interview. This quasi experimental research using pre-test-post-test control group design was conducted to 43 first-year undergraduate students as control class and 45 as experimental class of chemical education at the University of Lampung. Misconceptions that were countered in this research are the existence of orbitals in atoms and the relationship of magnetic quantum numbers to orbital orientation. This research aims to apply simple graphical visualization tool named Winplot for a learning exercise activity and explore its potency to counter misconceptions about orbitals and quantum numbers. 4, 2016 ABSTRACT Misconception is one of the most widely researched topics in science education, including chemical education.
