Abstract

Online learning became one of the most popular learning strategies during the pandemic of Covid-19 in every level of education in Indonesia. This type of learning strategy certainly has an impact on developing student’s learning habit and also thinking habit. The impact of the implementation of online learning need to be measured to reveal the changes as the result of learning strategy which was adopted by the educators. This impact needs to be studied from the mathematical habit of mind as the point of view. The research method was survey research with population all students of mathematics education study program in Lampung University. Simple random sampling was used as the sampling technique to obtain 191 students in even semester of the 2019/2020 academic year as the sample.  Data collected using questionnaire which measured variables self-perception mathematical habit of mind and implementation of online learning. Data analyzed using simple linear regression on α = 5%. Based on data analysis, it can be concluded that the equation of the regression that express the relationship of self-perception mathematical habit of mind (Y) and implementasion of online learning (X) is Y = 0,246 X + 38,572 which indicates that there are significant low impact of implementation of online learning on students self-perception mathematical habit of mind

Abstract

This qualitative study aims to describe the conceptual understanding of prospective mathematics teachers at STKIP PGRI Lumajang by determining examples and non-examples of functions. This research was conducted by giving tests and interviews with 12 subjects. Data were analyzed using Miles & Huberman model.  This study showed that the subjects investigated whether paired to determine a given statement is a function or not. Subjects focus on specific expressions, e.g., or others that they have previously recognized as a function. However, some subjects used the vertical line test to determine a given graph represents a function or not, although they were unable to explain why the vertical line test was the appropriate method. Their understanding is limited to procedural knowledge such as mental representations and incomplete concept images, then failing to be comprehensively linked to the definition of the concept of function

Abstract

The purpose of this study was to analyze the validity and reliability rubric of performance appraisal on geometry subject matter using the many facet rasch model approach through the Facets software. Data were collected from 100 small-scale students and 250 large-scale students in junior high schools using 3 raters. The performance assessment instrument in the form of a rubric is used to assess the student's process of working on the questions, each question has a different rubric. The Rasch Many Faceted Measurement Model (MFRM) is used to analyze data by looking at three aspects, namely the facet person, rater agreement, and difficulty domain using the Facet program. For the facet person, the rater separation ratio was 4.96, while the reliability of the separation index was 2.15 which indicates that the assessors are separated reliably. The stratum index is 3.21 which indicates that there are three strata of rater severity that differ statistically in the sample of these 4 raters. The rater agrement obtained the reliability of the rater separation of 0.87 and the correlation between each assessor and the other ranged between 0.40 and 0.63, indicating adequate agreement among the raters in assessing test participants with their level of competence. The Difficulty Domain on the variable maps shows that the hard to soft range is from about +1 to −1 logit.

Abstract

The tobacco epidemic is one of the biggest public health problems in the world. Based on the data from WHO, Tobacco kills nearly 6 million people a year around the world. Monitoring tracks of smokers' growth population can be important things for the government to find the best implement policies to overcome this problem. This paper presents a smoker's growth model with uncertainty in the transmission and recovery rate. In classical smoker's growth model, the transmission and recovery rate assumed to be constant. However, in reality, the age of the population is heterogeneous, and the transmission among the population may depend on the age of the smoker. Therefore, in this paper, the transmission and recovery rate of smokers' growth model depends on the age of smokers. We divide the transmission and recovery rate into three categories based on age: Children (0-10), Adolescent (10-30), Adult (30-60). The uncertainty of transmission and recovery rate in this model represented by a triangular fuzzy number. The most important things in the model are the basic reproduction number. A basic reproduction number is an indicator of when the endemic case will occur. Therefore, the main focus of this paper is to determine the basic reproduction number of fuzzy smokers growth models using the fuzzy expected value concept. The result is the basic reproduction number of the fuzzy model is an interval. This may can be used as an upper and lower limit of the basic reproduction number

Abstract

Buyung dance is a traditional Sundanese dance that reflects the Sundanese community in taking water. Also, the meaning of a pitcher is a kind of tool made of metal or clay, often used by some village women in earlier times to take water in rivers, lakes, or ponds. When viewed closely, the Buyung dance formation has mathematical concepts such as the field of geometry, transformation of the geometry, and the counts and measurements made by the dancers in performing the Buyung dance. Besides, each formation also has its philosophical significance. This research is a qualitative study. The researcher directly goes to the field, studies a natural process of discovery through the process, records, analyzes, interprets, and reports, and draws conclusions from the process. Data collected through observation, interviews, and documentation. Based on the research, it was concluded that the beauty of the formation in the pitcher dance was identical to the pattern of the Frieze group. also, the formation formed has a philosophical meaning that reflects the local wisdom of the local community

Abstract

Algebraic reasoning is an important skill for students to support in learning mathematics, especially on algebraic topics. This research is aimed at describing students’ algebraic reasoning to solve problems based on Keirsey's personality types. This research used qualitative with a descriptive approach and was conducted involving four students who have equal mathematical abilities and the same gender. The selected students represented Keirsey’s personality types. The selection of students was carried out through two types of tests, namely the Keirsey Temperament Sorter (KTS) and the Mathematics Ability Test (MAT). The result showed that students with Guardian and Idealist personality types liked to use regular and coherent procedures to solve the problem. Then, students with rational and artisan personality types prefer to use complete explanations. So, teachers can improve students' algebraic reasoning skills by facilitating each student based on their personality type, such as developing learning activities that can include every student's algebraic reasoning ability

Abstract

Mathematical textbooks are one source of learning that has an important role in learning activities. But the existence of the government-issued mathematics textbook (BSE) which is currently widely used in class X high schools, still does not know the quality of its cognitive aspects. The purpose of this study was to find out the questions contained in class X high school mathematics textbooks had met the criteria of a good question according to the Marzano cognitive aspects. Qualitative descriptive research was used to analyze competency test questions in mathematics books. Data was collected through a question categorization checklist based on Marzano's cognitive aspects validated by experts. Guidelines for question analysis based on Marzano's taxonomy's cognitive aspects consisted of levels of cognitive retrieval, levels of cognitive understanding, levels of cognitive analysis, and levels of cognitive knowledge. The results showed that the percentage of question distribution for the recall rate was 17%, at an understanding level of 14%, 30% analysis level, and 39% knowledge level; in other words, cognitive distribution in high school mathematics class X textbooks was still not ideal according to proportional allocation of aspects cognitive
