<![CDATA[The effective learning can be built by comprehend the students’ prior knowledge. However, it is rare for teacher to arrange learning based on students’ alternative concepts, particularly be related to force and motion concept. Based on those problems, this research is aims to describe student’s mental model about Newton’s Third Law. The methods is testing by four essay items about to action-reaction forces. Those items asked students to explain, predict, and evaluate the phenomenon which is related to Newton’s Third Law. The sample include 140 students from 3 provinces in Indonesia, that consist of D.I Yogyakarta, South Borneo, and West Borneo. The results showed that there is many students held diverge mental model about action-reaction forces. The divergences among others are: the greater the mass, the greater the force in collision phenomenon; the resting object can’t exert reaction force; the action-reaction forces can be cancelling each other. The suggestion to overcome those mental models is discussed. We hope these result can be applied by others teachers to construct better leaning about Newton’s Third Law.]]>

<![CDATA[Intermolecular force is the topic in Organic Chemistry 1 course. Organic Chemistry 1 subject mainly involves abstractive and complex concepts. Therefore, many students face difficulties even get a misconception. This research aimed to identify the students' understanding and misconception in Organic Chemistry 1 lecturing especially about intermolecular forces topic. The study was a quantitative descriptive research. The research subjects were 50 fourth semester Chemistry Education students of 2015-2016 of State University of Malang that have taken Organic Chemistry 1 course. The research instruments were three-tier test namely multiple choices test with open reason and Certainty of Response Index of six items. The conclusion of research result is that 30% of the students still underwent misconception in Organic Chemistry 1 lecturing especially for intermolecular forces topic. The finding of some misconceptions encountered by the chemistry students were the strength of van der Waals forces of more electromagnetive element is more easily polarized; there is no electron withdrawing group in the organic molecules that have dipole-dipole forces so that there are no δ+ and δ-; there is a hydrogen bond in CH3(CH2)2CHO compound; the students did not understand the compound which can form hydrogen and water bond; the hydrogen bond is formed in polar compound; the bond between O-H in CH3(CH2)2COOH molecules is a hydrogen bond; and the strength of intermolecular forces of certain organic molecule is only influenced by electronegativity where the higher the electronegativity the greater the intermolecular forces.]]>

<![CDATA[This research aims to unveil elementary schools’ reasoning process in understanding the phenomenon of falling fruit with their limited knowledge about it. This research employed qualitative approach with the approach of The Investigation of Lived Experience assisted with Cognitive Psychology. The data of this research were obtained by written test and interview. The subjects of this research were the students of 4th and 6th grade with the samples of 3 students in each class. The result showed that the reasoning of elementary school students were mostly inductive. Only one respondent had deductive reasoning. The result also showed that the case of p-prims with inductive analysis was caused by analogy and intuition, while p-prims with deductive analysis happened due to inadequate ability to explain certain phenomenon. Misconception was formed by two inductive reasonings, (1) inductive reasoning with unrelated premises and (2) inductive reasoning with related premises; however, incorrect preposition. Other findings related to this research is the initial understanding of the respondents was formed as p-prims and some other was formed as misconception.]]>
