This study aims to address the teaching of integrals in multivariable calculus concerning the role taken by geometry, specifically, geometrical content dealing with boundaries in integrals that appear as curves and surfaces in R[superscript 2] and R[superscript 3]. Adopting the framework of the Anthropological Theory of the Didactic, we approached…

Local wisdom contained in the Sasak community needs to be continuously preserved and become a local value or tradition that is believed to be true until now. The development of forms of local Sasak wisdom in this study is integrated into the concept of family economic education, especially in educating children from elementary school age. This…

With the development of mobile communication technology and the widespread popularization of mobile devices, mobile learning (m-learning) as a new learning model has achieved rapid development in many fields. Therefore, it is essential to clearly describe the knowledge development trajectory and research topics in the field of m-learning. This…

Learning that empowers students' environmental literacy needs to be encouraged considering the increasing environmental damage. This study aimed to reflect on educational programs on environmental sustainability by measuring the environmental literacy of high school students and identifying the relationship between environmental literacy domains.…

Teachers' practical knowledge is closely related to teaching practice. The purpose of this research was to develop an instrument for assessing upper-secondary school science teachers' perceived practical knowledge about practical work. The development of this instrument was based on five components in the conceptual framework of PCK about…

Regarding future ecological challenges, it is highly relevant for students to understand the processes within ecosystems and the effects of external influences on their conservation. Since ecosystems are complex, difficulties in learning are often examined from a systems thinking perspective. However, challenges also arise in other areas,…

This paper presents the ways that reflective questions were used to develop pre-service mathematics teachers' understanding of metric and topological spaces. In particular, the purpose of developing PSTs' understanding of metric and topological spaces is that understanding these mathematical concepts leads to PSTs' understandings on how to teach…

Background: Knowledge of the structure and function of the human heart is fundamental to accurately understanding human physiology. As a complex biological system, naïve conceptions abound regarding cardiac anatomy and physiology for K-12 learners and medical students alike. Objective: Textbooks and lectures, as well models and simulations, have…

This paper explores faculty's perspectives and use of open educational resources (OER) and their repositories across different countries by conducting a multiple case study to find similarities and differences between academics' awareness, perceptions and use of OER, as well as examining related aspects of institutional policy and quality that may…

Students spend much time in doing their physics homework. Whether this effort results in deep learning depends on the quality of the mere homework. Therefore, we designed a minds-on simulation-based approach to physics homework and conducted a pretest-posttest quasi-experiment to compare its effectiveness to the effectiveness of traditional…

Facing recent threats of coronavirus disease (COVID-19), an educational strategy was designed and applied to middle school students in order to reinforce related knowledge and behaviors. A group of 65 middle school students (14-18 years old) developed several designed online curricular activities. After the intervention, students answered a…

Extension concept mapping is a technique to connect prior existing concept maps with new knowledge structures. It offers advantages in each stage of the knowledge-integrating process and encourages learners to improve their performance. While previous studies have confirmed that the extended kit-build concept map outperformed the extended…

Purpose: This paper aims to explore student perceptions of recycling and explore whether one university's strategy helped or hindered student recycling in their university's halls of residence. There is near-universal acknowledgement of the urgency of the climate crisis, yet household recycling rates remain low at 45.2%. Student-recycling rates…

Since the concept of sustainability is linked to the problems of daily life, educational games are an important tool to teach this concept and to reveal perceptions about this concept. This study aims to determine science teachers' views on the concept of sustainable development through educational games. This study is a phenomenological study.…

The implementation of science reform must be viewed as a systems-level problem and not just focus on resources for teachers and students. High-capacity instructional leadership is essential for supporting classroom science instruction. Recent reform efforts include a shift from learning about science facts to figuring out scientific phenomena in…
