Authors: Nurhayu Winati , Putra Bobby Permana , Maretta Gres , Mulyana Jeane Siswitasari , Darmawan Andy
Published: June 2023

The preference for using the right or left hand for different uni-manual tasks is known as handedness. Handedness as functional asymmetry has a correlation with the asymmetric brain. Most types of tools have been developed for right-handed use, leading to different adaptations between left-handed and right-handed individuals. Visuospatial, as one of the cognitive processes, is the ability to visualize two- and or three-dimensional objects. This function allows individuals to remember, plan for the future, navigate, and make decisions, thus visuospatial is one of the primary mental aspects in humans. The aim of this study was to assess whether being left-handed was associated with visuospatial ability. Respondents in this study were 148 adult individuals who lived in Lampung Province. Handedness was assessed based on a questionnaire of self-confessed and hand preference of 10 daily activities. Hand grip performance was measured by using a hand dynamometer. The ability of visuospatial was assessed by using the Right-Left Discrimination method. The results of the visuospatial ability test showed that left-handed individuals had a better average score of visuospatial than right-handed ones (44.00 > 40.86). Males had better visuospatial ability than females (estimate = -0.0768; p-value: 0.0481). The influence of handedness on visuospatial ability was discussed

Published: June 2023

The Merdeka Belajar policy essentially aims to accelerate the achievement of national goals of education. One of the major changes in the policy is the implementation of the National Assessment (NA) which substitutes national exams and changes the focus of assessment into literacy and numeracy skills. This leads to a demand for teacher to adapt learning process and classroom assessment for facilitating students’ literacy and numeracy skills. Therefore, teacher understanding about the element in national assessment is a very important factor in the implementation of National Assessment. As the response, this study collects data about teacher understanding from 100 elementary and junior high school teachers in the Kuningan Regency area. The results shows that the elementary and junior high school teachers already have a good understanding of the objectives of NA and awareness that the implementation of NA would have an impact on providing a more varied learning and assessment experience. However, it is shown that the good understanding and awareness is not supported by capability to develop literacy and numeracy questions. The support for improving capability in making questions that align with the NA is needed in order to provide appropriate measurement and assessment of student learning outcomes and provide the basis for decision making in the classroom learning process.

Authors: Septianingrum Dinni , Mizuno Kosuke , Herdiansyah Herdis
Published: June 2023

Solid waste management, which always ends in landfills, causes various environmental and socio-economic impacts. Tegal City also experiences overcapacity landfill conditions because the waste management model focuses on landfills. This study aims to identify existing waste management regulations and how EPR can become a policy framework to achieve waste management beyond landfills. The result explains that by regulation, the government has regulated the flow of solid waste management by prioritizing the 3R principles, starting from the transportation process, sorting at TPS/TPST, and even processing to become a product with economic value. However, in the end, all this waste still ends up in landfill. From the government's perspective, this is due to the need to integrate responsibilities between the government, society, and producers. Producer responsibility must be fully implemented in waste management. However, several regulations have yet to regulate the form of waste management that producers can carry out the responsibility of producers as specifically to be responsible for the product until it ends up as waste. In addition, this study illustrates that EPR as a policy framework for waste management can be applied in other cities, primarily if the government's point of view supports the division of responsibilities for waste management.

The results showed that the induction of gamma ray mutations affected the character of plant height, flag leaf angle, flowering age, panicle length, number of filled grains per panicle, harvest age, and grain weight per clump. Comparison plants and mutant plants showed an interaction on all observed characters, except the number of total tillers and the number of productive tillers. Wide genetic diversity was shown by all characters, except flag leaf angle, total tiller number, weight of 100 grains, and weight of empty grain per clump. High heritability was obtained on the character of plant height (0.97), flag leaf angle (0.74), flowering age (0.99), number of productive tillers (0.57), panicle length (0.86), number of filled grain per panicle (0.92), number of empty grains per panicle (0.55), age at harvest (1.00), and weight of 100 grains (0.99).

Published: June 2023

This article discusses the relationship between mathematics learning outcomes and natural science learning outcomes at East Teluk Jambe 1 Public Middle School in 227 students from nine classes at the end of the odd semester of the 2022/2023 Academic Year. The relationship between these two subjects can be seen from the results of mathematics learning scores and science learning scores by looking at the relationship that occurs based on student ability categories, namely the High Mathematics Category (HMC) and the Low Mathematics Category (LMC), the High Science Category (HSC), the Low Science Category (LSC) is then also seen based on the overall value of mathematics and science. The statistical test used is a correlation test to see each relationship. The results obtained the overall value of mathematics learning outcomes will have a sufficient influence on the overall value of science learning outcomes and vice versa, the effect of a sufficient relationship in the value of mathematics learning outcomes on science or vice versa occurs when students' learning abilities in mathematics or science are high. The overall mathematics learning result is 83.20 while the average science learning result is 85.63, and the science score is higher than the math score. Students who study mathematics will have an influence on learning science, and vice versa students who study mathematics will have an influence on learning mathematics so that these two subjects must be given to students

This study aims to describe the implementation of technological pedagogical and content knowledge (TPACK) in learning in senior high schools. The research approach used is qualitative with descriptive type. Data was collected by conducting in-depth interviews and data analysis using analysis using the Miles and Huberman model with the stages of data reduction, data presentation, and drawing conclusions. The results of this study indicate that the implementation of TPACK in SMA has not been implemented optimally. This is because there are several obstacles encountered such as the unavailability of facilities that support optimally in several schools. The facilities in question include internet networks and learning tools in the form of computers and LCDs. In addition, the increase in the ability of teachers to implement TPACK-based learning is still uneven. This is a challenge in applying TPACK to learning optimally. The alternative chosen in learning is to use conventional learning by utilizing the facilities available at school.

The development of PhET-based core physics introductory teaching materials to increase the activities and learning outcomes of physics education students has been successfully carried out. The purpose of this development is to produce teaching materials for introductory PhET-based core physics courses that are feasible to increase the activity and learning outcomes of physics education students. The device development uses a 4D model (define, design, develop, and disseminate). The tools developed are in the form of Semester Program Plans, Student Activity Sheets, core physics teaching materials, student activity instruments and student learning outcomes instruments. The results showed that the PhET-based core physics teaching materials were very valid. This means that the teaching materials for introductory core physics courses based on the use of PhET are very feasible to use in increasing the activities and learning outcomes of physics education students.
A Case Study of R&E Instruction for Middle School Students: Focusing on the Search for Winning Solutions of NIM Games and the Development of Modified NIM Games
Authors:   Korean Science Education Society for the Gifted, Song Sang Hun
Published: June 2023

This is a case study of R&E instruction for middle school students in Science Gifted Education Center who explored the winning solution of the NIM game, a type of two-person finite turn-based fixed complete information game, and modified the game. It is not difficult for middle school students to understand the solution of the NIM game and solve the problem while obtaining the logical sum expressed in binary. However, unlike the enrichment course, R&E education for gifted students explores new mathematical properties beyond the given problem-solving method, and experiences the rediscovery of principles, reinvention of forms, and re-creation of games through various transformations (making, development). We should be able to guide them through these methods. As a result of re-creation mathematics through recreational activities, students created a modified NIM game that extended it in addition to several known modified NIM games. The results of this study can be used for the development of modified NIM games and will be helpful for teaching R&E in the secondary school course.
