Abstract

This learning media aims to assist students in increasing understanding of mathematical concepts, being able to explain the relationship between concepts and the application of concepts or algorithms in a flexible, accurate, efficient and precise way in problem solving. The advantage of this educational game is that there are several materials that are equipped with animations, sound images and quizzes so that they can generate enthusiasm and interest in students in learning mathematics. The results of observations that have been made at SDN 1 Trangsan are that mathematics learning carried out in schools is not fun or still uses the lecture method in learning so that mathematical concepts are not conveyed. In this study, the method used was RD (Research and Development) and the ADDIE development method (analysis, development, design, implementation, evaluation). This media has been tested on 3 media experts and obtained the result that the average coefficient V is 0.90 and can be declared valid. While the results of the reliability test from media experts is 0.710 and can be stated as strong reliability. While the material was tested on 2 accompanying teachers in elementary schools who obtained an average value of coefficient V of 0.92 which was declared valid. The results of the material expert reliability test obtained a value of 0.768 and declared strong reliability. The results of the interpretation test of the percentage of tests carried out by 10 respondents or students obtained a percentage value of 67.4% which was included in the "Agree" category. The results of the pretest and posttest can be concluded that the value of sig 0.05, which means the data is normally distributed.

Abstract

Genetic literacy is the capacity to obtain, process, understand, and use genetic information. It is highly imperative in life science students; the current study was conducted to assess genetic literacy in students. The goals of the current project are (1) to assess the Genetic Literacy of life sciences students in education colleges, and (2) to identify how Genetic Literacy changes according to variables of academic level, gender, and different universities in education students in universities of the Furat Al-Awsat. To achieve the project's goals, the two researchers used the analytical-descriptive method using the steps such as an examination prepared to assess the impact of the variables of interest. Experts then reviewed it to confirm its legitimacy, clarity, and suitability to the target audience. The testing timing was then inferred using a trial on a sample consisting of 40 students that belong to the target audience. The test was then applied to a sample of 395 students in the second semester of the academic year 2020-2021. The sample was randomly selected from the universities of Al-Qādisiyyah, Karbala, and Kufa. The statistical packages, SPSS-26, and Microsoft tool, Microsoft Excel, were used to process the collected data and show that education-department students of the selected universities did not possess Genetic Literacy. Varying gender did not have a statistically clear impact on Genetic Literacy. Differences in genetic literacy were identified between 3rd and 4th-level students and their 1st and 2nd counterparts. The researchers concluded the necessity of integration among the contents of education and genetic literacy applied to the size, type, and quality of the material and activities in the curriculum. They also suggested that further studies must be made to study the relationship between students' level of genetic literacy and that of educators.

Abstract

Having self-confidence is very necessary in living life in order to be able to pass the stages of development well. Appearing with confidence is one of the keys to success in living life with a social environment such as friends and society. Without self-confidence, individuals will experience many problems within themselves. One of the factors that influence self-confidence is interaction and parenting applied by parents. The purpose of this study was to determine the relationship between perceptions of authoritarian parenting and self-confidence in high school students in Yogyakarta. This study uses a quantitative method with a correlation approach. Respondents in this study were high school students in Yogyakarta. The number of respondents as many as 80 students. The sampling technique used was purposive sampling. Data retrieval using scale filling. Data analysis using Pearson Product Moment correlation. The results showed that respondents had a perception of authoritarian parenting in the medium category with a percentage of 86.3% (69 people), while the respondents' self-confidence was at a moderate level with a percentage of 85% (68 people). Based on the data on the results of the determination test (R Square) which shows that the test results (R²) are worth 0.115 or 11.5%. Perceptions of authoritarian parenting contributed 11.5% to self-confidence. There is a significant negative relationship between the perception of authoritarian parenting and self-confidence in high school students in Yogyakarta. So that the higher students' perceptions of authoritarian parenting, the lower their self-confidence, and vice versa, the lower students' perceptions of authoritarian parenting, the higher their self-confidence.

Abstract

Long acknowledged as the foundation for a country's growth and prosperity are four disciplines- science, technology, engineering, and mathematics (STEM).  Education in these four fields has several advantages for women in terms of long-term social and economic advancement. By 2030, the fifth sustainable development target (SDG 5) is to enable women and girls to realise their full potential. One of the criteria to determine SDG 5 is measuring gender equality in science, technology, engineering, and mathematics (STEM). In Taraba State, Nigeria, this study looks into gender equality in STEM fields. The study sample consists of 14,548 STEM-majoring students from 100 secondary schools and 6 post-secondary institutions in Taraba State, with 8,354 male and 6,194 female participants. Data on enrollment in STEM-related courses as well as information from a standardised survey were collected.The findings show that enrollment data at the secondary school level is equal for both sexes. Nonetheless, more male students chose chemistry and physics, while more female students chose biology and technical drawing. According to the tertiary institutions' findings, men predominate in STEM fields. The study comes to the conclusion that there is significant gender inequality in STEM education in Taraba State, Nigeria, and suggests that efforts should be taken to bridge the gap in order to meet SDG 5.

Abstract

Robotics is predicted to become the fastest growing market that could contribute to global socio-economic prosperity. The increasing unemployment rate and demand for 21st-century skills dictate the development of coding and robotic skills in STEAM fields. Schools are implementing the development of coding and robotics skills in curricula, but teachers are not effectively trained for teaching these skills. Therefore, the study employed a qualitative approach to detect how educators (n=22) of a higher education institution could be effectively trained in coding and robotics. The results showed that educators preferred working collaboratively in small groups, enjoyed the training activities, observed and understood the application of theory into practice, still required hard copy manuals, found robotic kit components too small to work on, were dependent on individual support during the training sessions, and required additional training sessions. Best practice in training coding and robotics is to ensure technical and pedagogical knowledge is connected and applied to real-life practices; divide trainees into basic and beginner classes, and sub-divide them in pairs where they can work collaboratively and interactively in completing their coding and robots; clarify the advantages and disadvantages of robotics in society; create fun activities during the training; and ensure sufficient support is available after training to assist those still not at ease with coding a robot.

Abstract

Modern information technology has brought great benefits to education and challenged teachers’ professional beliefs. This study collects data about Chinese college teachers’ professional beliefs with the methods of questionnaire surveys and individual interviews. Based on 682 valid questionnaires, the study finds that Chinese college teachers’ professional beliefs are positive in general. Their research capabilities and their sense of research achievements are lower than their teaching abilities and their sense of teaching achievements. In addition, they expect to improve their information technology capabilities eagerly. Given research findings, this study proposes strategies to reconstruct the teachers’ professional beliefs, such as offering training and further education opportunities for college teachers, improving their research capabilities, intensifying the reform of colleges to establish a classified evaluation system, and providing information technology training for college teachers.

Abstract

Questionnaires are commonly utilized on educational research. However, studies on Differential Item Functioning (DIF) and calibration using Rasch Models are still limited. Therefore, a Self-regulated Learning questionnaire was developed which aims to determine the ability of students to regulate themselves to achieve learning goals. The instrument consists of twelve items. The involved participants were 300 students who enrolled in first-year to fourth-year. Data were analyzed using Racsh Model Analysis with Winsteps 4.5.2 software. As a result, there are four items that were not fit, so that, therefore should be eliminated or revised. The DIF analysis found that gender bias was unidentified, but long-study bias was detected for items number one and six. The reliability value of the item is categorized as very good (0.99), which indicates that the instrument has sufficient consistency/reliability. While, the function curve showed that the items on the self-regulated learning questionnaire produce optimal information in individuals with moderate (θ) ability. Overall, self-regulated learning questionnaires have to be revised then tested on different sample groups. In addition, longitudinal and cross-sectional research is necessary to determine the level of self-regulated learning of students more comprehensively.

Abstract

This study investigates lesson study research trends through bibliometric analysis on widely distributed Google Scholar (GS) and Scopus databases. We reviewed 997 papers from GS and 200 documents from the Scopus database searched using Harzing's Publish on May 6 2023. A descriptive study approach was used to investigate the data. The result of this study is that the number of lesson study documents has increased over the last decade (2012-2022). The most productive author based on GS  is R Huang from the United States, and the full author based on Scopus is E. Saito from Australia. While the prominent authors based on the highest citations are Fernandez Yoshida, based on GS, and Dudley, with the highest citations based on Scopus. The “International Journal for Lesson and Learning Studies” in the last decade is the most source of lesson study documents. Based on VosViewer visualization, Rosa is the author who has the most co-authorship papers and total link strength. The VosViewer displays four clusters related to lesson study: community, context, observation, and participation. Our strong recommendations regarding this study are lesson study research related to literacy, numeracy, and mathematical abilities. The results can assist relevant researchers in understanding trends in lesson study research and recommend guidelines for other studies.
