In this paper, we show briefly outcomes of a pedagogical study using numerical methods, in particular the Arithmetic of Infinity, in teaching infinity for undergraduate level (for the detailed study, see [15]). This methodology, introduced by Yaroslav Sergeyev in 2003, provides a new way to deal with infinite quantities and infinitesimals. Though it is different from the methods used in traditional mathematics, those which are adopted in most school curriculums worldwide, yet it doesn't contradict those methods. The study presented in this paper highlights students' beliefs of mathematical infinity, as well as their ability to learn and use the new methodology. The results of evoking the Arithmetic of Infinity in school teaching seemed to be promising as it provides easy methods for computing infinite quantities and infinitesimals. In addition, students' beliefs of the mathematical infinity turned to be more confident and positive after being subject to the new method. [ABSTRACT FROM AUTHOR]

In order to improve the quality of education in Indonesia, the government created a program called accreditation which aims to improve the quality of education based on the National Education Standards (SNP) which pays attention to 8 educational standards. In addition, accreditation aims to motivate schools/madrasah to continue to gradually improve the quality of education at the district/city, provincial, national, and even regional and international levels as well as to help identify schools/madrasah in the context of providing assistance. A school/madrasah that meets the eight characteristics according to the SNP is accredited A, for those who lack/have not met the accreditation other than A. Executive Director of the National Accreditation Board for Higher Education (BAN-PT). This study specifically compares three supervised machine learning methods, namely k-nearest neighbor (kNN), logistic regression and classification tree. The results of the accuracy of the three methods show that there is no significant difference in the accuracy, the accuracy produced is almost the same for the three methods, 79-80%. Based on the measurement scale on the independent variable data, namely numeric and categorical, it will be inconvenient to classify using the kNN method because we have to standardize the data first. Meanwhile, logistic regression and classification tree, the difference in measurement scale in the data is not a problem. However, the author prefers to use a classification tree because by using a classification tree we can see the classification process and also know what variables are used as factors that distinguish the response variables.

Living in the 21st century is not easy, primarily due to the abundance of accessible information. Consequently, the next generation must possess scientific literacy. In response to this issue, modern schooling must prioritise the development of thinking skills among students. In this regard, scientific process skills hold great importance within the context of science education. While there are numerous reports on scientific process skills available in scholarly literature, the evaluation of these skills through an online test with a proper theoretical framework is rarely documented. Therefore, this study aims to bridge this gap by employing a cognitive domain framework. We designed an open-ended test to measure students' scientific process skills. The instruments used in the study were validated for content and construct validity. Prior to implementation, the instrument was pilot-tested and met the criteria for reliability. Furthermore, 54 students from several junior high schools in Kediri District, Indonesia, participated in this study. The distribution of male and female students was 35.8% and 64.2%, respectively. In summary, the study revealed that the students' basic and integrated scientific process skills were at low levels. Additionally, the influence of gender on students' scientific process skills was also examined in this study. [ABSTRACT FROM AUTHOR]

This study endeavours to develop a questionnaire instrument capable of classifying respondents based on their tendencies towards divergent or convergent thinking. The questionnaire serves a valuable purpose by enabling teachers to identify the thinking potential of individual students and maximise it during the learning process. The research involved 149 junior high school (SMP) students from the West Lombok district, who participated in the stages of validity and reliability testing, and 84 respondents in the categorisation trial. The instruments were compiled and assessed through expert validation using descriptive methods, employing percentage scores. Additionally, validity was assessed using product moment correlation coefficients, reliability was measured through alpha reliability coefficients, and categorisation abilities were evaluated based on non-level categorisation (nominal). The findings revealed that the divergent and convergent categorisation questionnaires consisted of 40 items, encompassing 20 descriptors each for divergent and convergent thinking. Expert ratings yielded an average score of 89.50, falling within the excellent category. The product moment test confirmed the validity of all 40 items, with a product-moment correlation value greater than the critical value (rtable (149, 0.05)=0.16). The reliability of the questionnaire was deemed high for both the divergent and convergent item groups and satisfactory for all items, as indicated by alpha reliability coefficients of 0.64, 0.72, and 0.55, respectively. The trial results demonstrated that the questionnaire effectively categorised subjects, achieving accurate categorisation for up to 20% of the total subjects in both the divergent and convergent thinking groups.

The research aims to develop science learning media using a valid, practical, and effective problem-based learning integrated Moodle web to improve the technological literacy of junior high school students. Learning media development using the stages of Lee and Owens (2004) includes assessment/analysis, design, development, implementation, and evaluation. At the implementation stage, it used a quasi-experimental research design with the type of pretest-posttest nonequivalent control group design. We conducted this research at Al Rifa'ie Gondanglegi Modern Junior High School, Indonesia. The implementation used two different classes: class VIII A as the experimental class (PBL with science learning media using PBL-based Moodle web) and VIII B as the control class using the PBL learning model. The validity test results of media, materials, and science education practitioners were 98.13%, 100%, and 99.37%, with the three categories being very valid. The results of individual, small group, field, and conduct pilot tests were 84.10%, 83.93%, 89.79%, and 86.32%, with very practical categories. The effectiveness test results using a single ANCOVA test with p < 0.05 showed that the science learning using the PBL-based Moodle web significantly affected technological literacy compared to students who were taught only with PBL. Science learning media using the Moodle web that has been developed can be used by science teachers. Furthermore, the PBL-based Moodle web can also be formed from other subjects to improve the technological literacy skills of junior high school students and various other 21st-century skills.

Qualitative descriptive research is the type of this research. This study aims to describe and determine which item indicators are difficult to use in solving social arithmetic problems in junior high school. The subjects in the study were students at State Junior High School 1 Galur, with 91 students in the 2020/2021 school year as the sample. Student test results and documentation were used to collect the required data. The data analysis techniques used by Miles are: (a) the collection of data; (b) the reduction of data; (c) presentation of data; and (d) drawing conclusions. The results of the research and data analysis showed that the indicators of difficult items in solving social arithmetic problems in junior high school were the indicator questions number 2 (predicting the amount of profit), number 4 (counting the amount of loss), number 5 (determining the largest and smallest discount in the table), number 6 (summing up the discount percentage), number 7 (formulating and solving problems related to discounts), number 8 (calculation of the largest tax and smallest tax), number 9 (determining the amount of money that must be returned), and number 11 (calculating gross, net, and tare). After the analysis, according to the researcher, the students' difficulties did not lie in the indicators and questions given. However, it also comes from the lack of students' ability to read the meaning of the questions and the lack of accuracy in counting. In addition, it is also possible that students are also in a hurry to work on the problem and also guess the answers without counting them. Another possible factor is that students are not used to working on HOTS questions. There is a need for additional learning related to the social arithmetic chapter so that students can better understand the intended material concept. [ABSTRACT FROM AUTHOR]

Assessment is one of the most important aspects in education, especially in the domain of knowledge and skills. The development of questions for assessment can be developed using the Solo Taxonomy containing four levels, namely the unit structural level, the multi-structural level, the relational level, and the expanded abstract level. This paper discusses how to develop mathematics assessment based on these four levels. Each level provides distinguished level of complexity in the domain. By levelling the mathematics assessments, it might be expected that teacher could get reliable data about student's achievement. It is argued that this model is more suitable when a reasoning skill is particularly assessed. Examples on how to develop the assessment in the topic for junior high school, proportion, is discussed in this paper. [ABSTRACT FROM AUTHOR]
