Abstract

In chemistry, an abstract material consists of three levels of representations that are macroscopic, sub-microscopic, and symbolic. However, many students have misconceptions due to the difficulty in understanding the relationship between the three levels representations. Misconceptions should be reduced or prevented as early as possible because it is resistant and difficult to change. Stoichiometry represents one example of chemistry material which consists of abstract concepts that usually lead to student misconceptions. The misconception in this material can be reduced if the wrong concept has already detected. Therefore it needed the tool that can detect and reduce these misconceptions. Software can be used as the tool to detect and reduce misconception because it has two functions as assessment and learning tool. Software must be said effective before it is used by student. So that this study aim is knowing the effectiveness of software to detect and reduce misconceptions in stoichiometry material. This study used Research and Development method. The result of this study shows that software is effective to detect and reduce misconceptions. It is proved by the average percentage of misconception shift to understand the concept about 80,13% which is categorized as effective.

Abstract

The development of the educational paradigm in the 21st century emphasizes learning oriented to higher-order thinking skills, one of them is metacognitive skills. This study aims to improve the metacognitive skills of students through a guided inquiry learning model based on blended learning in reaction rate material. The research design used is One-Group Pretest-Posttest Design. The research was conducted in class XI MIPA 5 SMAN 2 Pamekasan. The data were obtained using the observation sheet instrument for the implementation of the learning model, the activities of the students, and the metacognitive skills test sheet. Data analysis was performed using the percentage, mean, n-gain, and paired t-test techniques. The results showed that 1) Guided inquiry learning model based on blended learning is carried out well with an average percentage of phase 1 of 94.88%, phase 2 of 100%, phase 3 of 97.92%, phase 4 of 98.44% and phase 5 of 96.88%, 2) The percentage of students' activities who are actively involved and relevant to guided inquiry learning model based on blended learning is 87.41%, 3) The metacognitive skills of students have increased in terms of the n-gain range, namely 0.53 - 0.62 with the medium category, dan 4) there is a significant difference in the results of metacognitive skills between before and after being given a guided inquiry learning model based on blended learning. The results showed that the guided inquiry learning model based on blended learning was effective in improving students' metacognitive skills

Abstract

ABSTRACT: In the early seventies received wide attention when Patai [1] published his book tagged the chemistry of the azomethane group and the aforementioned group is very important in the fields of chemistry, life sciences, chemical and pharmaceutical industries and medicine. The chemistry of imines includes two main groups is Schiff bases and oximes. as well as   presence of double bonds in the imines facilitated the possibility of their presence in the form of two Geometrical Isomers. Curtin and Husser [2] are among the first to discover the presence of imines in two forms, syn and anti, and the inability to separate these two forms in the imines is attributed to the freedom to rotate around the double bonds between The carbon and nitrogen atoms, which reduce the occurrence of the polarization process in C=N and facilitate the rotation process [3]. Keywords: tautomerism, organic chemistry, azomethane group

Abstract

This research is motivated by teachers who are still not ready to face distance learning during the Covid-19 pandemic. To overcome this problem researchers take corrective actions through school action research which aims to improve the ability of teachers and researchers to provide personal assistance using the Google Classroom application program for learning. distance and improve school performance in order to be able to compete in the field of graduation. The research design uses a qualitative design, while the data collection technique uses the method of documentation and observation. The data analysis technique was carried out through a qualitative descriptive model consisting of data reduction, data presentation, and drawing conclusions. The results of this study can be seen from the increase in the results of the ability of the participants in personal assistance and the implementation of activities by resource persons from before the action in cycles I and II. In the pre-cycle of participants who got an average score of 3.52, the percentage was 88.04% with the "Very Good" category, there was 1 person while the average score was 3.12, the percentage was 78.12%, the conversion value reached 3, the next 6 participants got a score of 2, the category "Quite Good". Based on the teacher's ability in the first cycle it reached 74.65% if converted the value obtained 3, with the "Good" category while in the second cycle it reached 87.49%, if the conversion value obtained a value of 4, with the "Very Good" category. Based on the implementation of mentoring by the resource persons in the first cycle, it reached 87.46%, if converted the value obtained 4, with the "Very Satisfactory" category while in the second cycle it reached 91.22% if converted the value obtained 4, with the "Very Satisfactory" category

Abstract

The preparation of a scientifically literate society is the main goal of science education throughout the world and this has resulted in the emphasis of nature of science in the curriculum. The purpose of this research project is to examine the aforementioned students’ views on NOS tenets, its relationship to their academic achievements and background, and how it changes through their study of science. The study took place at the City College of New York, an urban, commuter, public college, and minority serving institute. The research data was collected through the administration of a survey that contained three of the NOS questions and academic and background information about the students. The data suggest that students possess inadequate understanding of the nature of science when they begin their academic fields of science study. This inadequate understanding is resistant to change in traditional science teaching settings. The data provide evidence that the inadequate understanding of nature of science does not change as the result of exposure to science courses, the field of science studied, and the students’ academic achievement as measured by grade point average. Our data show that traditional instruction in college science courses does not address nature of science and does not cause a conceptual change in the students’ understanding of NOS. The lack of correlation between students’ understanding of nature of science and credits completed or grade point average could be attributed to students relying on rote-learning and algorithmic problem-solving to achieve high grades and succeed in science, which hinders their meaningful learning of science and the development of conceptual understanding. Thus, science teaching and instruction should address naïve conception on the NOS and changes the instruction methods to consider NOS naïve conceptions and learning challenges. Science teaching and learning curriculum and instruction should immerse students in science learning activities that nurtures their understanding of the nature of science through participating in novel science research and inquiry-based learning activities.
