The learning of laboratory skills is essential in science education, but students often get too little individual guidance in this area. Augmented reality (AR) technologies are a promising tool to tackle this challenge and promote students’ high-level learning and performance in science laboratories. Thus, the purpose of this study was (1) to design an AR-assisted learning environment to support individual knowledge construction, (2) to investigate students’ learning processes and learning outcomes and (3) to examine the usability of the system. Pharmacy students (n = 16) were assigned to experimental (n = 10) and control (n = 6) groups and performed the same laboratory work together with pre- and post-tests. The experimental group worked with AR glasses that provided additional support and timely guidance during the work with additional info-screens, questions related to choosing correct reagents and laboratory tools and think-aloud questions, whereas the control group worked in a traditional laboratory context. The results showed that AR was more effective in fostering performance in the science laboratory compared to traditional laboratory instruction and prevented most of the mistakes. The AR group considered the guidance and feedback provided by AR to be beneficial for their learning. However, no apparent differences were found in tasks measuring students’ understanding of the content knowledge. Thus, an AR environment embedded with supportive tools could partly replace the teacher in science teaching laboratories by providing individual and timely guidance for the students.

This study aims to analyze the problematic analysis of science learning based on local wisdom and the solution in terms of its solution in terms of several aspects, namely: curriculum, teachers, students, learning strategies, assessments, facilities and infrastructure. This type of research is descriptive qualitative. The research data was obtained through literature review and giving questionnaires to 65 respondents. The respondents came from 201 teachers who are alumni at one of the universities in Mataram City who are members of WAG IKA (WhatsApp Group Alumni Association). The questionnaire contains a list of six open-ended questions. The results of the study provide information that curriculum changes are expected to answer the needs of the times and consider local wisdom according to the characteristics of each region, these changes require mental changes from curriculum implementers. The quantity of teachers is sufficient but the quality of teachers still needs to be improved, especially in designing learning tools based on local wisdom. From the student factor, the role of parents as well as motivation and interest in learning is important to improve so that learning outcomes are as expected, and students also care about local wisdom in their neighborhood. For this reason, teachers need good learning strategies in planning local wisdom-based learning processes in the classroom by considering authentic assessments that are able to measure aspects of students' attitudes, knowledge, and skills in learning science. Facilities and infrastructure that can support science learning activities based on local wisdom include: library facilities, science laboratories, multimedia laboratories, and objects of local wisdom around students.

Abstract. Paleomagnetism is a relatively unknown part of Earth sciences that is not well integrated into the school curriculum in the United Kingdom. Throughout recent years, there has been a decline in the number of Earth science students in the UK. In 2018 and 2019, we developed outreach activities and resources to introduce the scientifically-engaged general public to paleomagnetism and raise awareness of how geomagnetism affects society today, thus putting paleomagnetism, and Earth sciences, in the spotlight. We tested our ideas at local events that were visited mostly by families with small children, with tens to hundreds of participants. Our project culminated in the ‘Magnetic to the Core’ stand at the Royal Society Summer Science Exhibition in 2019, which is visited by members of the general public as well as students and teachers, scientists, policymakers and the media. At this event, we communicated the fundamentals of paleomagnetism through hands-on experiments and presented our recent research advances in a fun and family friendly way. To test the impact of our exhibit on knowledge of paleomagnetism and Earth’s magnetic field on visitors, we designed an interactive quiz and collected results from 382 participants over 8 days. The results show an increase in score of 19.1 % between those who had not yet visited the stand to those who had visited for more than 10 minutes. The results from school-age respondents alone show a larger increase in score of 28.1 % between those who had not yet visited and those who had spent more than 10 minutes at the stand. These findings demonstrate that this outreach event was successful in impacting visitors’ learning. We hope our Magnetic to the Core project can serve as an inspiration for other Earth science laboratories looking to engage a wide audience and measure the success and impact of their outreach activities.

In recent years the degree of automation in life science laboratories increased considerably by introducing stationary and mobile robots. This trend requires intensified considerations of the occupational safety for cooperating humans, since the robots operate with low volatile compounds that partially emit hazardous vapors, which especially do arise if accidents or leakages occur. For the fast detection of such or similar situations a modular IoT-sensor node was developed. The sensor node consists of four hardware layers, which can be configured individually regarding basic functionality and measured parameters for varying application focuses. In this paper the sensor node is equipped with two gas sensors (BME688, SGP30) for a continuous TVOC measurement. In investigations under controlled laboratory conditions the general sensors’ behavior regarding different VOCs and varying installation conditions are performed. In practical investigations the sensor node’s integration into simple laboratory applications using stationary and mobile robots is shown and examined. The investigation results show that the selected sensors are suitable for the early detection of solvent vapors in life science laboratories. The sensor response and thus the system’s applicability depends on the used compounds, the distance between sensor node and vapor source as well as the speed of the automation systems.

Many solutions such as percentage, molar and buffer solutions are used in all experiments conducted in life science laboratories. Although the preparation of the solutions is not difficult, miscalculations that can be made during intensive laboratory work negatively affect the experimental results. In order for the experiments to work correctly, the solutions must be prepared completely correctly. In this project, a software, ATLaS (Assistant Toolkit for Laboratory Solutions), has been developed to eliminate solution errors arising from calculations. Python programming language was used in the development of ATLaS. Tkinter and Pandas libraries were used in the program. ATLaS contains five main modules (1) Percent Solutions, (2) Molar Solutions, (3) Acid-Base Solutions, (4) Buffer Solutions and (5) Unit Converter. Main modules have sub-functions within themselves. With PyInstaller, the software was converted into a stand-alone executable file. The source code of ATLaS is available at https://github.com/cugur1978/ATLaS.

The blended laboratory model in this study refers to an integrated laboratory concept combining synchronous (real laboratory activities) using the Internet of things (IoT) and asynchronous learning with augmented reality (AR). The application of blended laboratory model in science learning teachers is still low in Indonesia due to the lack of ICT support for online learning. This preliminary study was conducted to analyze the need for the development of the blended laboratory model with IoT and AR involving 45 science teachers and 42 junior high school students as the respondents with stratified random sampling technique. The research method employed survey and focus group discussion. The results of the study showed that (1) 67% of teachers and 92% of students have never used AR, (2) 72% of teachers and 89% of students have never utilized IoT, (3) 65% of science laboratories in the junior high school do not have proper devices for AR application, (5) 76% of science laboratories in the junior high schools are not facilitated with proper equipment for the IoT application, (6) the respondents stated that the development of blended laboratory is very important (72%) and important (18%) to support IT-based learning, especially to deal with the conditions after the Covid-19 outbreak.  ©2021  JSER.
