Communication Styles During Teaching Learning Process in EFL Classroom

This research was aimed to analyze communication styles during teaching learning process in classroom. The research was conducted by using qualitative descriptive design. The data of this study were the utterances of teaching learning process in a classroom which is a conversation classroom in an English Institution Course, which was transcribed into the written form. The conclusion that can be drawn is that all of the types of communication styles basically occurred in the teaching and learning process. The types of physical communication styles are aggressive, passive, passive – aggressive, and assertive. In the teaching and learning process, assertive communication styles was the dominant communication style happening in the process for 67%, followed by Passive as 16%, passive – aggressive 12%, and aggressive 5%. It showed that the assertive communication style is the dominant style that is used in teaching and learning process as this style is the good style to comfort people while communicating each other. So, to convey message especially in teaching learning process, it is needed an effective communication to achieve the nature of the learning itself

Online learning sentiment analysis during the covid-19 Indonesia pandemic using twitter data

Abstract In the last week of September 2020, Covid-19 in Indonesia has infected more than 252,000 people. The spread of the virus through physical contact forces all countries to use social distance and physical distance to reduce interactions. On the educational side, the Covid-19 pandemic has had an impact on the prevention of face-to-face teaching and learning activities. All educational institutions must stop the learning process and replace it with online learning. Nadiem Makarim, Minister of Education and Culture of the Republic of Indonesia, then affirmed this online learning by issuing a policy on online learning in case of an emergency spread of the Covid-19 virus. However, this online learning has provoked debate in the community over the preparation of the technology. The goal of this study was to analyze public opinion for online learning during the Covid-19 pandemic in October 2020. The research carried out document-based text mining and feelings on Twitter data analyzed using the Naïve Bayes method. Analysis in that period found 25 percent positive sentiment, 74 percent negative sentiment, and 1 percent neutral sentiment. Several tweets showed that the words ‘stress’ and ‘covid’ were the most commonly spoken in the month.</jats:p

Implementation Of The Nature Of Science And Social Sciences In The World Of Education

Implimentation of the nature of science and social science in the world of education aims to form a mindset and mindset of feeling towards students who are more consistent in learning so that education is realized that gives birth to future generations with a scientific mindset, with concepts, principles, theories and emotional and social intelligence in each individual student. The method of theoretical studies and observations in schools that science and social sciences cannot be separated from the learning process in the world of education, from the results of data testing that we have carried out that social phenomena are always related to their environment. Implementation of the nature of science and social science in the world of education that there are vibrations and energy waves to carry out an activity in learning which essentially already exists in each individual. Data processing results using spss for windows obtained Fhitung=13.618 with sig. 0.000 and Fhitung= 8.385 with sig.0.001 from for Ftable= 3.19 the results obtained in relation to the implementation is very significant

Determining symmetry groups ongeometric builds using reflection and rotation tests

Abstract This research is motivated by the researcher’s desire to see the folding and rotational symmetry in geometric shapes whether they meet the symmetries for certain aspects and form a group. The method used in testing the symmetry of a group in geometric shapes is by testing reflection and rotation with a combination of linear and abstract algebra using an ordered matrix, where the geometric shapes are traced on each particular aspect until they meet the symmetry. From the results of the method used, it is found that the triangles to the octagon groups are symmetrical through the test of rotation and reflection of the geometric shapes. Thus, it can be concluded that group symmetry occurs up to the order of eight in geometric shapes. Based on the pattern, starting from the pentagon it is not a symmetry group, the hexagon includes the symmetry group, the heptagon is not a symmetry group, the octagon includes a symmetry group, then the nonagon is not a symmetry group and the decagon belongs to the symmetry group</jats:p
