In this paper, we present an alternative for physics laboratory activity related to Fraunhofer diffraction in distance learning. The activity utilizes a demonstration video from MIT Open CourseWare, Tracker software, and spreadsheet. An online demonstration video is used because it is the most accessible resource during undesirable conditions such as COVID 19 pandemic. In the activity, students can explore diffractions phenomena with multiple slits. The effect of slit spacing and slit numbers to the intensity of light is investigated trough spectral analysis with Tracker. The investigation is followed by a discussion through the mathematical approach and visualization with spreadsheets. It will enrich students with a theoretical explanation of the observation. This distance learning activity allows students to develop their science process skills, mathematical and computational thinking skills, and conceptual understanding of Fraunhofer diffraction.

The title of this paper is Fraunhofer diffraction simulation using spreadsheet and GNU octave media as an alternative for learning during the pandemic. This paper aims to present an alternative to distance learning during the COVID-19 pandemic by using simulations using spreadsheets and GNU Octave media. Optical practicum in physics laboratories can not be done during pandemics. So the solution that can be offered is to use simulations on optical subjects of diffraction material. In the simulation making activities students can learn and explore about the phenomenon of diffraction. Simulations using the equations used in the research of Zhang et al. in 2013. This simulation is used to visualize the effect of variations in different parameters such as wavelengths and gap widths in Fraunhofer diffraction patterns. This paper has successfully simulated Fraunhofer's diffraction using spreadsheets as well as GNU Octave. This distance learning allows students to develop fraunhofer computational computational skills and conceptual understanding of diffraction

Background and Purpose: Formal learning in schools generally does not provide enough engagement for students to grasp the science concepts and skills taught to them. Therefore, the structured informal learning activities such as STEM (Science, Technology, Engineering, Mathematics) integrated project-based learning is vital for students to partake in the more meaningful science learning process as it involves interdisciplinary activities. Hence, this paper discusses the study that underlies the structured informal learning activity, the STEM project-based approach, in enhancing conceptual understanding and inventive thinking skills among secondary school students.   Methodology: A quasi-experimental research design concerning treatment and control groups with pre-test as the covariate was employed in this project. The sample was selected based on the purposive sampling approach. Seventy Form Four students (33 male students and 37 female students) from a secondary school in Kedah, Malaysia were divided into 35 students of a controlled group (received conventional approach) and 35 students of the treatment group (followed STEM project-based approach). Data collected via the Newtonian Conceptual Understanding Test (NCUT) and Inventive Thinking Skills Test (ITST) were then analysed descriptively and inferentially.   Findings: The structured informal learning activity, the STEM project-based approach, was found effective in enhancing conceptual understanding and inventive thinking skills among secondary school students.  Further analysis showed that the elements of thinking skills (management and adaptation to complexity, self-regulation, curiosity, creativity, risk-readiness, and high-order thinking skills and sound reasoning) were also improved among students who followed STEM project-based approach.   Contributions: The study highlighted the importance of a structured informal learning activity, such as the STEM project-based approach in assisting students to grasp the science concepts and develop the required 21st-century learning skills besides formal learning in schools.   Keywords: Conceptual understanding, inventive thinking skills, Newtonian physics, physics education, secondary school students.   Cite as: Saleh, S., Muhammad, A., & Syed Abdullah, S.

This study aims to describe the increase in activities and student learning outcomes in learning Natural Sciences in class V Kabuyu Inpres Elementary School through the application of the science process skills approach. The method used in this research is classroom action research which consists of 4 stages, planning, implementation, observation, and reflection, with data collection techniques using evaluation tests, observation sheets, and field notes. Research subjects were 27 students. The results showed that using existing instructional devices showed an increase in student and teacher activities. Student learning activity shows the percentage score obtained on the first cycle is 70.05% in the category enough, in the second cycle showed an increase in the percentage score of 90.48% category very good, an increase of 20.43%. Teacher observation activities when applying the material in class I showed a percentage score of 78.33% in the good category, in the second cycle, the percentage score was 95.00% in the very good category, an increase of 16.67%. In the results of the analysis of evaluation tests, the first cycle students showed the percentage of classical completeness 53.70% for the percentage of classical absorption 71.06%, the second cycle showed an increase in the results of the evaluation test evaluation on the percentage of climax completeness obtained 90.74%, and the percentage of absorption laxative results showed 84.96%, KBK increased by 37.04% and DSK increased by 13.90%. Based on the acquisition of these results, it was concluded that the approach to science process skills can improve student learning activities and outcomes in the heat transfer material in class V of Kabuyu Inpres Elementary School in 2018-2019.

The computer science (CS) unplugged approach intends to teach CS concepts and computational thinking skills without employing any digital tools. The current study conducted a systematic literature review to analyze research studies that conducted investigations related to implementations of CS unplugged activities. A systematic review procedure was developed and applied to detect and subsequently review relevant research studies published from 2010 to 2019. It was found that 55 research studies (17 articles + 38 conference proceedings) satisfied the inclusion criteria for the analysis. These research studies were then examined with regard to their demographic characteristics, research methodologies, research results, and main findings. It was found that the unplugged approach was realized and utilized differently among researchers. The majority of the studies used the CS unplugged term when referring to “paper–pencil activities,” “problem solving,” “storytelling,” “games,” “tangible programming,” and even “robotics.”

Background. Escape rooms have been utilized to incorporate teamwork, communication, policy, and procedures reinforcement, as well as clinical care. Often themed, escape rooms challenge a team of players to discover clues and sequentially solve puzzles with the ultimate task of accomplishing a specific goal in a limited time frame, fostering critical thinking. Method. This learning activity incorporates legal implications for prelicensure nursing students in a pediatric community summer camp/after school care environment. Care and legal implications for a minor experiencing respiratory distress was the premise of this escape room. Outcomes. While this was not a research study, surveys were distributed for quality improvement and a deeper needs assessment related to the content and delivery of an escape room. Learners discussed the positive aspects of this activity through journal entries and a survey, noting the need for increased content related to legal implications for the medical team. This room engaged the learner in the forward-thinking that is needed related to emergency care, Good Samaritan Act, liability for cost, and permission to treat in a time-pressured environment. Future Plans. Testing the knowledge pre-post survey related to legal implications with implied care will be explored.
