Student Misconception

The problem of this research is the finding of wrong conceptual understanding by students on vibration and wave material. Wrong understanding of the concept results in misconceptions in cognitive aspects, scientific attitudes and student skills. This study aims to analyze student misconceptions with the Certainty Of Response Index (CRI) model through the edmodo quis feature. The subjects of this research were students of the PGSD STKIP MB Study Program for the 2019/2020 Academic Year. This type of research is qualitative research using descriptive methods. Furthermore, the research instrument used an objective test instrument. The results of this study are in the form of evaluation test kits that have been validated from the aspects of the content of the material and language by the experts. The results of the validation of the material content aspect were 93.75% in the very good category, the question construction aspect was 96.42% in the very good category and the language aspect was 90.6% with the very good category. This shows that the question has the feasibility of being applied. The test results showed that the misconceptions experienced by students regarding the wave material were very diverse. The average student misconception on vibration and wave material was 23.17% with the low category.

<p class="JIPIAbstractBodyEnglish">Misconceptions are an obstacle in the learning process, especially in physics. One way to detect misconceptions is to use a three-tier diagnostic test and analyze it using the Certainty of Response Index (CRI). The purpose of this study was to detect students' misconceptions on straight motion material using a three-tier diagnostic test with CRI analysis. This type of research is descriptive research. The sample in this study was taken from students at three high schools in East Lombok district, NTB. The number of samples in this study was 132 students. This test instrument consists of 10 question items. The results showed that students still experienced many misconceptions in straight motion material.</p>

This study was aimed at identifying the misconception of Mathematics Education students in the formulation of research methods in their proposals. This study was descriptive quantitative. The population consisted of 195 students of Mathematics Education Department, year 2014, Sarjanawiyata Tamansiswa University. The sample was collected using exhaustive sampling on the entire research population. Data were collected by documentation and closed-option questionnaires. The data were analyzed by descriptive statistical analysis. Analysis of Certainty of Response Index (CRI) was used to find out errors and misconceptions. The results show that most of the students have good understanding in the concepts of research methods. The other have misconceptions and limited understanding. The student misconceptions occur in the aspects of population, research variables, operational definitions and instrument reliability. The students do not explain fully and clearly the operational definition of the variables studied. On the aspect if reliability, errors are made by the students in the unexplained explanation of the reliability test used for the test instrument.MISKONSEPSI MAHASISWA PENDIDIKAN MATEMATIKA PADA KONSEP METODE PENELITIANAbstrakPenelitian ini bertujuan untuk mengidentifikasi kesalahan penyusunan metode penelitian dalam penulisan proposal.

This research aimed to describe the student misconceptions and find out the cause of misconceptions on Redox Reaction lesson at the tenth grade of Senior High School 9 Bengkulu in 2018/2019 Academic Year. Research conduct on April 15th until May 24th, 2019. The design of this research is descriptive method. The samples were taken through simple random sampling technique are 67 students of tenth grade MIPA SMA N 9 Kota Bengkulu so that 30 students were sampled. Essay test by Certainty of Response Index (CRI) and interview were used as the instruments of this research. Based on the analysis of research data shows there are misconceptions students. The analysis results show that misconceptions occurred at all sub concept on redox concept so the percentage of misconceptions that occur amounted to 35,7% in the overall student. The results showed the highest percentage of misconceptions in the amount of 46% at sub concept to determine reduction oxidation based on oxidation number on molecules and ion. The lowest percentage of misconceptions in the amount of 23% at indicator to in the sub concept of understanding oxidation and reduction in a redox reaction in terms of changes in oxidation number. Based on the results of interviews, causes of student misconception are derived from internal and external factors. Internal factors are derived from students such as students' associative thinking, student apperception and wrong intuition, students' abilities are lacking, low of students' motivation and learning interests during the learning process, students' learning methods, and students' selfconfidence in CRI values and external factors such as methods learning and limited learning resources.

ABSTRACTThis study aimed to describe the student misconceptions and find out the cause of misconceptions MIPA class X SMAN 1 Pontianak. The method used is descriptive qualitative approach. The technique of taking informants using purposive sampling techniques so that the informant obtained, namely class X MIPA 5 and 6. The data collection techniques such as measurement results of diagnostic tests and interviews. Data collection tools in the form of Multiple Choice Tests using Certainty Of Response Index (CRI), which consists of 10 items with five alternative answers and guidance interview. Based on the analysis of research data shows there are misconceptions students. The results showed the highest percentage of misconceptions in the amount of 63.93% on indicators to distinguish the concept of oxidation and reduction in terms of incorporation and release of oxygen and misconceptions lowest percentage that is equal to 4.92% on the indicator to distinguish the concept of oxidation and reduction in terms of release and acceptance of electrons. The cause of the misconceptions of students caused by the fault of students that includes associative thinking students, preconception or early concept is wrong, intuition is wrong, and the ability of students but it is also caused by the teaching methods are boring and less varied and selfconfidence of students is too great when filling criteria CRI.Keywords: student misconceptions, misconceptions cause, reaction oxidation reduction

The forest ecological security of the Yangtze River Economic Belt has an important influence on improving the regional environment and promoting the sustainable development of the social economy. Therefore, the aim of this paper is to provide countermeasures and suggestions for improving the level of regional ecological security by quantitatively analyzing the forest ecological security status of the Yangtze River Economic Belt and the tributaries of the Yangtze River. Using three main aspects, i.e., resources, socio-economic pressure and maintenance response, the study established 26 indicators that affect the forest ecological security of 11 provinces (cities) in the Yangtze River Economic Belt. The index weights were determined by principal component analysis, and the forest ecological security levels of 11 provinces (cities) in the Yangtze River Economic Belt were classified and evaluated by the grey clustering method. The results show the following: (1) the principal component analysis determined the weight of the three aspect indicators. The order is as follows: resource index > socio-economic pressure index > maintenance response index. This means that the basic environmental condition which the forest growth depends on and quality and quantity of forest is most important, and the maintenance activities performed by human beings in forest resources need to be strengthened. (2) The level of the forest ecological security in all the provinces (cities) of the Yangtze River Economic Belt is relatively good, with an upward trend. The level of forest ecological security in each province (city) decreases from the upper reaches of the Yangtze River basin to the lower reaches, and the level of forest ecological security in the central cities is lower. (3) The resource index, socio-economic pressure index and maintenance response index of all the provinces and cities showed an upward trend in these four years. The provinces with a significantly higher forest resource index include Yunnan and Guizhou. Shanghai, Chongqing, Sichuan, Hunan and Jiangxi were the provinces with significantly higher socio-economic pressure values; Yunnan province, Shanghai, Jiangxi Province and Hubei province were the provinces with higher forest maintenance response values.
