Learning Indonesian in elementary schools can help students get to know themselves, their culture and other cultures, express ideas, participate in society, and discover and use the analytical and imaginative abilities that are present in them. In the implementation of Indonesian language learning there are many gaps, so it is less able to achieve the specified learning objectives to the maximum. This research was conducted in class 5 of Totosari Elementary School No. 102 Surakarta, Indonesia. The purpose of this research is to explore obstacles in the process of learning Indonesian in elementary schools. This research uses a case study approach. Data collection was carried out by observing the Indonesian learning process, interviewing, and examining the average student test scores. The collected data were analyzed using interactive analysis according to Miles and Huberman. The results of his research are 1) The teacher has not used the media in the learning process especially Indonesian Language learning; 2) Learning is carried out is still conventional; 3) Students in learning tend to memorize subject matter. Through learning innovations that are in accordance with the characteristics of elementary school students are expected to be able to create meaningful learning.

This study aimed to develop an instructional design that focuses on programming teaching for gifted and talented students and to investigate its effects on the teaching process. During the development of the instructional design; the steps of Morrison, Ross and Kemp Instructional Design Model were followed. Embedded experimental design, one of the mixed-method research designs, was used in the modeling of the study. The participants consisted of students studying at the Science and Art Center (BILSEM) (experimental group: 13 girls and 12 boys, control group: 10 girls and 15 boys). While the instructional design developed by the researchers was applied to the gifted and talented students in the experimental group, the standard activities used in Information Technologies and Software Courses at BILSEM were applied to the gifted and talented students in the control group. “Computational Thinking Scale (CTS)”, “Torrance Creative Thinking Test (TCTT-Figural)” and “Computer Programming Self-Efficacy Scale (CPSES)” were used to collect the data of the quantitative phase of the study. Qualitative data were gathered by using interview form, observation forms, and design thinking rubric. Two-Factor ANOVA Test, Bonferroni Adjustment Multiple Comparisons Test, and interaction graphs were used to analyze quantitative data while qualitative data were analyzed by content analysis. The quantitative results of the research showed that the instructional design was effective on students' computational thinking and creative thinking skills, but not on programming self-efficacy. Qualitative findings revealed that the instructional design helped the students learn the computational concepts, use computational applications, and develop computational-perspectives. Also, students improved their design thinking skills to a certain level and expressed that they enjoyed the design thinking process, learned the course content, and experienced some difficulties.

The curriculum of an elementary school of Indonesian education currently emphasizes the affective aspects as a result of student learning for the sustainability of national development. This fact encourages teachers the responsibility to create and develop effective learning tools to foster tolerance, nationalism, be communicative and friendly, love peace, and social care. The objective of the study is to analyze the needs of students in elementary schools towards the development of educational comics to foster character development. This study uses qualitative approach. Participants were 120 fifth grade students. A questionnaire was used to collect the data of the study. The data were analyzed using an interactive model. The results of the study revealed that there was an interest of students in comic media as a teaching aid containing local wisdom values for character education. In the aspect of construction, comics are needed that are related to the ideal scope and size of the comics. In the aspect of content required comic material set in a national culture containing local wisdom, presentation of the story with the contents of an illustration of nationalism and social awareness. As for the design aspect and appearance, characterizations of cartoons are needed, involving a variety of colors, fonts of proportional size. The conclusion of this research is the development of educational comics media with local wisdom is needed to fulfill the needs of elementary school students as an effort to foster character.

The article focused on the use of assessment for learning in promoting active learning and learner participation in mathematics. Assessment for learning (AfL) has been found to enhance learning and improve performance. However, teachers’ use of AfL to enhance active learning has not been clearly outlined. This study is part of the broader research study that explored mathematics teachers’ use of AfL to enhance mathematics teaching and learning in primary schools in Alexandra Township, Johannesburg. A case study research-type and a qualitative approach were used to collect data from mathematics teachers. Nine teachers were purposefully selected from whom data were collected using semi-structured interviews and non-participant observation. The findings revealed that teachers had limited pedagogical knowledge in using AfL to promote active learning in their classrooms. They failed to apply a learner-centred approach that promotes effective learner participation in mathematics classrooms. Therefore, it is recommended that teachers undergo ongoing continuous development on classroom time management and planning for the effective use of AfL.

The Coronavirus disease (COVID-19) pandemic has increased anxiety and stress among teacher education managers and has given rise to the question of whether they have the competencies to execute their operational responsibilities productively. The theories of resilience and transformational leadership underpin this study in which teacher education managers’ resilience and their responsiveness to the well-being of staff executing their operational practices in an open distance e-learning context were explored. A qualitative approach was adopted and virtual video conferencing interviews with teacher education managers were used to explore how they mitigated their strategic and operational roles and their managerial functions to ensure the well-being and organisational performance of staff working from home. Results revealed the experiences of distance managers to have been positive in that they implemented organisational strategies to mitigate the challenges faced to ensure wellness and performance among staff working from a distance. Further research applying a mixed-method design should be undertaken to determine how resilient managers and staff working from home are. That may yield different results.

The teaching and learning of mathematics in South Africa are conducted through the authorised Language of Learning and Teaching (LoLT). South Africa has eleven official languages, and English is a Language of Learning and Teaching (LoLT) from the Intermediate and Further Education and Training (FET) Phase. This study explores teachers' views on code-switching as a communicative technique to enhance teaching mathematics in Grade 4 in selected primary schools in South Africa. This qualitative single case study employed the interpretivist paradigm and social constructivism theory. A convenient purposive sampling technique was used to sample six grade 4 mathematics teachers from three primary schools in the Alexandra township in South Africa. Researchers collected data through the use of semi-structured interviews, which were later analysed and discussed using themes. Findings indicate that teachers often code-switch from LoLT (English First Additional Language) into Home Language (H.L.) to enhance learners' understanding of the mathematics concepts. Researchers suggested the integration of code-switching into the curriculum policy and followed by in-service training for Grade 4 mathematics teachers in code-switching.

During the period of the Coronavirus disease (COVID-19), the boundaries between the home and the school as study spaces were blurred. School studies entered the home, with the parents present and observing their children’s e-lessons and the teachers’ teaching methods. The purpose of the current study was to explore the explicit and implicit attitudes of the lesson partners: teachers, parents, and students, to e-learning. The study explores whether and to what degree the attitudes of teachers, students, and parents to e-teaching are compatible, and what are the implications for the future. The study shows that although in recent years the relationships between parents and the school and between teachers and students have waned, with regard to the separation of authorities between the home and school, the period of the COVID-19 crisis clarified the need to enhance the relationship and cooperation between the home and the school as two meaningful study spaces for independent learners. The research findings raise the paradox that not only does technology not increase the distance rather it has the potential to strengthen the relationships between parents, teachers, and the school. The study points to the need to prepare holistic guidance sessions and professional development courses.

Evaluation of the K-13 curriculum (2013 Curriculum) on the value of the national mathematics examination “Nilai Ebtanas Murni” (NEM) in every State Junior High School needs to be carried out thoroughly in order to improve the quality of education. This study uses spatial analysis to evaluate the curriculum and determine the development of NEM scores in the school year. Furthermore, the kriging interpolation method via surfer software was used to generate scores. The results showed that the 2015 K-13 mathematics curriculum did not give good results based on the 36-68 NEM score interval for the entire Pekanbaru area. In addition, the curriculum only gives good results for a small area in the north and south. In 2016, the curriculum which was accompanied by the entry of the new education unit level curriculum “Kurikulum Tingkat Satuan Pendidikan” (KTSP) showed a significant change in the NEM value. Although most of these areas experienced an increase in scores, the intervals still ranged from 36-68. The total revision of the K-13 curriculum carried out and used in 2017 showed a significant increase in scores for all regions with an interval of 68-84 scores. In conclusion, this study shows that the revision of the K-13 curriculum is the right step to produce quality mathematics learning.

The importance of literacy is a competency requirement that must be possessed by students to face competition in the 21st century. This is directly related to the extent to which students' scientific thinking processes understand and solve problems. This study aims to describe how literacy is trained in learning in junior high schools. The approach used is a qualitative approach with the type of phenomenological research. The participants in this study were 5 junior high school teachers who teach in the Special Region of Yogyakarta. Data was collected through virtual interviews with the help of the Google Meet platform. The data analysis model used is the model of Bogdan and Biklen with data collection procedures, data reduction, verification and conclusion. The results showed that literacy was trained on students with the habit of reading textbooks for 15 to 30 minutes every day by reporting their readings in student journals, teacher efforts in changing project and problem-based learning methods and strategies according to student conditions, and teacher habituation in providing HOTS level questions to train students' critical thinking processes, balance theoretical understanding and understand the surrounding environment.

Teacher professionalism is needed for quality education. The current practice for increasing teacher professionalism is to use skill applications. However, the implementation of skill applications has, in fact, not succeeded in significantly increasing teacher professionalism. This study aims to explain the importance of an effective skill application model coupled with a comprehensive approach to raise the level of teacher competence. This study is qualitative with its data derived from observations, interviews, and questionnaires. The paper's research findings show that existing programs are not sufficiently enhancing teacher competencies and professionalism. Various teacher professional development activities are conducted; however, there has been no continuous post-activity follow-up. These professional development activities tend only to fulfill the administrative requirements for teacher promotion. What is needed is a comprehensive and continuous teacher professionalism assessment model, which is underpinned by a system of mentoring. This study has implications for evaluating the teacher's professional competencies. More comprehensive skill applications need to be formulated as part of an integrated, sustainable, and mentoring [terpadu, sustainable, pendampingan-TSP] approach to develop teacher professionalism significantly.

This study aimed to develop an instrument to assess science teacher candidates’ professional and pedagogical competence in the Industrial revolution 4.0. The instrument consisted of 30 questions and was used in the main study, which was analyzed using the Rasch model to unravel the reliability and empirical validity. The questions were developed based on a predetermined grid including the skills and literacy aspects used in the industrial revolution 4.0. The 30 revised questions were then tested on 60 students of Science Education at two State universities in Indonesia who were in their third year of study times. The Rasch model was employed to test its reliability and empirical validity that included Wright map analysis, item difficulty level, distractor analysis, and item suitability with the Rasch model. The results showed that the reliability value of the professional aspect was .95 and classified as an excellent category. Moreover, the pedagogic aspect obtained .93 and was classified as a very good category. Only one question was the most difficult and did not fit the Rasch model, while the others already fitted. This reliable and valid instrument is suggested to be useful in assessing pre-service science teachers’ competence.

This study aims to develop a learning model based on 4C skills to improve high school students’ mathematical critical thinking skills. Research & development is the design used in this research by applying Plomp’s development theory which consists of three phases, namely needs analysis, design and implementation, and evaluation. This research was conducted at Madrasah Aliyah Negeri 2 Parepare, South Sulawesi, Indonesia involving five experts, four teachers, and 20 students. Data collection and analysis were carried out qualitatively and quantitatively. Analysis of interviews’ data and observations qualitatively with the thematic analysis technique. We also analyse data from validation sheets, questionnaires, and mathematical essay tests with the help of SPSS 20.00. The results show that students and lecturers need a learning model to improve mathematical critical thinking skills. In addition, other findings stated that the learning model developed was proven to be valid, practical, and effective to be used in general. Developing your learning model can further improve students' learning outcomes and mathematical critical thinking skills because they are designed based on the actual needs and problems. For this reason, a teacher must be able to design his learning model.

This research aims to explore students' learning obstacles in solving fraction problems in elementary school. This qualitative research used a case study method. The research subjects involved 30 third-grade elementary school students from two different schools in Bandung City, Indonesia. The instruments utilized were test and non-test. The test technique was done by giving fractional material questions, while the non-test technique was in the form of interviews. The data collected were then analyzed employing the three stages of the Miles and Huberman model, including data reduction, data presentation, and drawing conclusions. The study findings revealed that students experienced epistemological obstacles, where students experienced limited knowledge, ranging from the basic concepts of fractions, fractional arithmetic operations, and fraction problem-solving. Based on these findings, teachers can construct learning designs with appropriate didactic situations as a follow-up to minimize the occurrence of similar learning obstacles in future fractional learning materials.

Traditional houses are part of the culture of every country. Indonesia is a country that has a variety of traditional houses. The traditional Banyuwangi house is known as the Using house. This house can be explored in terms of ethnomathematics and used as part of learning mathematics. This research is focused on knowing and describing mathematics learning that integrates the ethnomathematics of Using house, thematic, and connected models. The research was also conducted to determine the effectiveness of the learning that has been carried out. The results showed that the use of the Using house in ethnomathematical-thematic-connected-based mathematics learning: (1) could be done using the trivium concept (literacy, matheracy, and technoracy); (2) can be done thematically by integrating four subjects (Indonesian, social sciences, fine arts, and mathematics); (3) can be connected by integrating two mathematical concepts (two-dimensional geometry and arithmetic); (4) through seven phases of learning; and (5) effective because 80% of students can solve problems as expected.

This study aimed to investigate the influence of innovation leadership on teacher commitment through organizational culture as a mediating variable. A quantitative approach using the survey method was used, and the sample was selected using proportional random sampling. The respondent consisted of 180 teachers from public vocational schools in Magelang. In addition, data were collected by questionnaire and analyzed by a structural equation model (SEM). The result showed that innovation leadership influenced organizational culture with a t-value of 2.95 > ttable (1.98) at .26. In contrast, organizational culture influenced teacher engagement with .27 and a t-value of 3.10 > ttable (1.98). Innovative leadership directly affected teacher commitment at .31 with a t-value of 3.41 > ttable (1.98) due to organizational culture being a mediating variable at .07. The overall influence on teachers' commitment through the organizational culture is .38. The analysis results explain that organizational culture can successfully mediate the relationship between innovation leadership to teachers' commitment. Therefore, these variables can be developed and implemented in schools to increase student achievement quality.

This study aimed to analyze the effect of game-based learning (GBL) through the use of Genially in English as a foreign language (EFL) online instruction. The participants were 61 EFL undergraduate students, who were distributed into an experimental group (32 students), and a control group (29 students). Their ages ranged from 22 to 56 years old, and their English proficiency level was B1, according to the Common European Framework of References (CEFR). The students were enrolled in two pre-intermediate courses that are part of an EFL Teaching program at a private university in southern Ecuador. The courses were delivered in an online remote learning environment due to the COVID-19 pandemic. The study followed a quasi-experimental approach and it took place over a sixteen-week period. The instruments included a diagnostic survey, a pre-test, a post-test, a students’ perceptions survey, and a semi-structured interview. The main findings revealed that Genially games have the potential to enhance EFL learners’ academic performance in online instruction, particularly in aspects related to students’ knowledge of grammar and vocabulary in context. Besides, it was found that according to students’ perceptions, the implementation of games based on their real learning needs increases their motivation, especially when feedback is effectively provided.
