Building awareness among students on the issues of natural environmental phenomena has always been a challenge due to the difference in location between the student and the observed phenomena. The issues of the natural environment have been a part of the curriculum in elementary schools. One of the lessons taught on the natural environment in elementary schools is related to the water condition in various areas filled with water, such as ponds, rivers, lakes, etc. Currently, learning in the natural environment is based on text, images, and videos, and learning activities using real-time data is still rare. This study presents the development of an IoT-based Smart Water Quality application prototype. The prototype consists of conductivity, pH, oxygen levels, salinity, and turbidity sensors. The IoT prototype can also be used to automatically monitor fish, shrimp, and other species in aquaculture ponds. Using the IoT-based Smart Water Quality application prototype, teachers can enhance students' higher-order thinking skills by designing learning activities using real-time data to identify, compare, and classify various concepts or phenomena.

The role of education in promoting global warming awareness is important to enable students to understand and address the impact of global warming. The use of Internet of Things (IoT) with collaborative learning strategies can enhance students' understanding of global warming. This study aimed to develop an IoT-based smart weather system enhancing the critical thinking skills of elementary students. It consists of weather-measuring sensors that capture data on temperature, humidity, air pressure, light intensity, and altitude. The data is stored in the Blynk cloud and displayed on smartphones. The IoT devices are placed in three different geographic locations. This paper presents the system design, including the system architecture and user interfaces. The data captured by the IoT sensors from the three measurement sites form the foundation to promote the development of collaborative learning. This result implies the need for teachers to creatively establish learning strategies in various subjects to improve students' critical thinking skills. [ABSTRACT FROM AUTHOR]

The closure of educational institutions to reduce the impact of the spread of COVID-19 has brought about a change in the education administration. Shifting the face-to-face learning process to an online learning system is one method to overcome this impact. The present study aims to assess the relationship between the online learning process and the achievement of graduate competence. The study was conducted by sharing the Constructive Online Learning Environment Survey (COLLES) questionnaire, which involved 626 responses from 49 schools of pharmacy in Indonesia to the graduates and re-taker of the Pharmacy Profession Program. This questionnaire has 24 items with six domains: relevance, reflection, interactivity, tutor support, peer support, and interpretation. The data were descriptively analyzed, and to find the correlation, the Student-T test was applied. This study showed that the highest score of the Constructive Online Learning Environment Survey (COLLES) domain is relevance (4.01). The lowest score can be seen in interactivity and teacher support. There are no significant differences in COLLES domains between graduates and re-taker groups. These findings also showed that the graduates' GPA significantly influences the student study success. It can be concluded that online learning during the pandemic did not influence pharmacists' achievement of minimum competency in Indonesia. [ABSTRACT FROM AUTHOR]
