The effect of differentiated instruction on academic achievement of grade eleven students in the field of derivative in Bhutan

Given the increasing diversity of students academically and culturally, educators are being called upon to accommodate students' diverse learning requirements through differentiated instruction strategies. In Bhutan, the Ministry of Education recently mandated the implementation of a differentiated instruction strategy in the K-12 curriculum. From this perspective, this study attempted to ascertain the effect of differentiated strategies on grade eleven mathematics students within the framework of the pre_test and post_test quasi-experimental research method. 64 grade eleven students participated in this study. The concept of derivative was taught using a differentiated instruction strategy for the experimental group (N=32) while a conventional one-size fits-all strategy was used for teaching the control group (N=32). A Conceptual Understanding Test on the Derivative (CUTD) was administered as pretest and posttest groups to examine the differences in their learning achievements. A t-test analysis of the pretests indicated no significant differences, indicating that the experimental and control groups' learning abilities on the concept of the derivative were roughly comparable. However, a statistically significant difference in favour of the experimental group over the control group was discovered in the post test analysis. It was recommended that Mathematics teachers and educators should embrace the use of differentiated instruction while teaching and learning derivative.The researchers also recommended that differentiated education be used over a prolonged period of time and with a larger sample size.

Developing a monograph book for teaching English skills to young learners in wetlands areas

To enable Universitas Lambung Mangkurat (ULM) to become the Asia-Pacific centre for wetlands development in 2027, one of the efforts ULM makes is to raise awareness about the importance of optimising human resources in wetlands through research and development in the educational and cultural fields. English is considered a foreign language in Indonesia, allowing students to use the language outside of academic settings. English becomes a required subject in junior and senior high school; however, the government requires that English be taught in primary schools as a local topic. English, on the other hand, remains a mandatory subject in a large number of Indonesian primary schools, particularly in Banjarmasin. The issue arises in primary school English instruction because there is no clear guidance for teachers on how to teach English in an appropriate and engaging manner for the students. Due to the absence of a monograph book on teaching methods, teachers in some primary schools in Banjarmasin, particularly those located in wetland areas, have limited access to teaching English to young learners (EYL). In light of the university's policy and the critical nature of achieving teaching and learning objectives, as well as the absence of a suitable reference book for teaching EYL, this study aims to develop an appropriate monograph book on teaching techniques for students of young ages. The research and development design is chosen because it aims to create a product and meets the needs of the reference book's development. The results are expected to improve students' academic performance and to assist EYL teachers in wetland areas in conducting effective and meaningful teaching.

University students’ perception of online learning: A case study of Virtual Class learning management system in the University of Lampung

The use of online media to facilitate distant learning during the pandemic has become one of the solutions that can be implemented to support the government's policy of reducing crowds in public spaces. In this case, students at the University of Lampung's Faculty of Teacher Training and Education benefit from an online management system called Virtual Class Unila. This platform is intended for students to use to access resources, download learning modules, and participate in classroom discussions. The Virtual Class was created to assist students with distance learning. However, since the initial implementation of Virtual Class at the start of the pandemic in early 2020, both positive and negative perceptions about its use have emerged. As a result, we were encouraged to ascertain diverse perceptions regarding the use of this sophisticated learning management system among students at the Faculty of Teacher Training and Education, University of Lampung. This study employed a quantitative approach, collecting data via a scaled survey questionnaire. The target participants were 272 students from various departments who were asked to complete a survey regarding their perceptions of the implementation of Virtual Class. The findings of this study are expected to be beneficial for the future maintenance and development of Virtual Class, as well as for determining the optimal method of conducting online learning.

The development of a STEM-based e-Module to help fifth-grade pupils strengthen their creative thinking skills in the topic of My Blood Circulation

Technology and education are now required for the development of 21st century skills. The purpose of this study was to determine 1) the practicality of STEAM-based e-Modules in online learning, 2) the importance of STEAM-based e-Modules in online learning, and 3) the improvement of students' creative thinking skills in fifth grade on the content "My Blood Circulation is Healthy." A total of 16 students were employed in the study. Questionnaires and tests were utilized as data gathering instruments. Problem and need analysis, literature review, product design, validation, and practitioner testing were the stages of development. The findings revealed that pupils' low creative thinking abilities were attributed to teachers' failure to adequately embrace technology and their continued usage of traditional instructional materials. The STEAM-based e-Module development improved creative thinking skills of Grade 5 students.

Inquiry-based E-LKPD in effort to improve the fourth grade students’ learning outcome

This study aims to determine 1) the feasibility of inquiry-based e-LKPD, 2) the importance of e-LKPD in the process of learning mathematics in elementary schools, 3) the improvement of students' mathematics learning outcome. The syntax of inquiry-based e-LKPD is student orientation to problems, organizing students to learn, guiding the investigation of individual and group participants, developing and presenting work results, analyzing and evaluating problem-solving processes. The data were collected through interviews, questionnaires, and tests. The results showed that the low thematic learning outcomes of students was due to the fact that educators had not fully used teaching materials and models that could improve learning outcomes, so it was hoped that the inquiry-based e-LKPD could improve the fourth grade students’ thematic learning. It is clear that inquiry is one of the learning strategies that can be applied as a solution in improving student learning outcomes, in accordance with the characteristics of the students. Therefore, it can be concluded that the inquiry-based e-LKPD to improve student learning outcomes in elementary schools needs to be developed.

The development of PQ4R-based LKPD to improve the fourth grade students’ thematic learning outcome

This research aims to analyze the need of LKPD development in accordance with the learning model used. This research was a descriptive quantitative research. The research subjects were teachers and students of grade IV at State Elementary School (SDN) 2 Kampung Baru. The data were collected using interviews, observation, and questionnaire, which were analyzed through a descriptive analysis. The results show that the competence standard, basic competence, and competence achievement indicators were in line with the Curriculum 2013. The students’ learning outcomes were categorized into low category. The PQ4R is one of models that can be applied for improving students’ learning outcomes. The teachers need a suitable LKPD for the learning model, suitable with students’ characteristics. This research can be further developed referring to the PQ4R learning model for improving learning achievement.

Ethno mathematics-based teaching materials for elementary school students
