In biology learning, the object of a virus cannot be seen directly. Augmented reality (AR) technology can help visualize the object of a virus in 3D, making it easier for students to learn about viruses. Therefore, this research aims to develop an AR-based learning media product called ARVi. ARVi was created using the ADDIE model, which consists…

Background: Early sexual reproductive health (SRH) education is linked to a reduction in risky sexual behaviors. Sexually transmitted infections (STIs) are rising at alarming rates. Risky sexual behaviors, including initiation of sex before age 13, having more than four sexual partners, and lack of use of condoms, increase the chance of infection…

This study examines the epistemic disciplinary knowledge that students consider when addressing a real food emergency that requires their engagement in inquiry and argumentation practices. The study comprised two phases: (1) designing an experiment to study the emergency and (2) evaluating the real outcome of the emergency. The participants were…

We designed and evaluated a student laboratory workshop on plant-based vaccines against the SARS-CoV-2 virus. The workshop focused on hands-on laboratory techniques, including DNA extraction from rice seeds, where the recombinant protein was produced, detection of the transgene, and basic concepts on how vaccines work in the human body to offer…

In this study, it was aimed to determine high school students' cognitive structures regarding to the immunity, infection, allergy and autoimmunity. In this study, it was tried to reveal the cognitive structures of high school students on immunity, infection, allergy and autoimmunity just before COVID-19. The study was carried out with 77 students.…

This paper presents an analysis of the socio-scientific dimensions which 46 11th graders, enrolled in the subject scientific culture, consider to justify their COVID-19 vaccination decision and how they managed to combine and integrate these dimensions before and after working on a sequence of activities aimed at learning about argumentation in…

Social studies texts often pose a challenge for readers because of their complex linguistics features, which can cause comprehension issues. Drawing upon Systemic Functional Linguistics (SFL), this study examines how authors create cohesive messages and meaning in an 11th-grade U.S. history textbook in relation to the history of diseases. Findings…

This article describes a modeling project the author did with his algebra, geometry, and applications students in grades 9, 10, and 11 as an enrichment and exploration of an extremely relevant real-world phenomenon and introduction to the adult profession of epidemiologist. With discussion and exploration, this project consumed two periods of 88…

"Kurikulum Merdeka" is a learning experience framework that offers flexibility and focuses on essential content, character development, and students' competencies. Teachers had the discretion to develop their modules to choose, design, and organize the learning contents for students, based on their needs. By using that module, there is…

This article details an experiment in an 11th and 12th grade 3-week intensive course, the Science and History of Contagious Disease. The course was an interdisciplinary survey of how diseases are spread along with an examination of social responses. Although both lecture and discussion based, the course revolved primary around a trip in which we…

As COVID-19 accelerated through spring of 2020 the question became how will schools cope with protracted closure? Devising strategies to engage and educate students through full-time, online learning became a priority. At Tufts CSE we specialize in creating high school biomedical science curricula that foster engagement with science and build…

Pandem-Sim is a live, distance-learning simulation where 10th-12th grade students perform as epidemiologists to investigate infectious disease outbreaks. Prior to a mission, teachers review content and introduce students to the sim interfaces. During the mission students analyze data concerning demographics, symptoms and patient histories for a…

Although early sexual initiation has been linked to negative outcomes, it is unknown whether these effects are causal. In this study, we use propensity score methods to estimate the causal effect of early sexual initiation on young adult sexual risk behaviors and health outcomes using data from the National Longitudinal Study of Adolescent to…

The stakes are high for sex education in South Africa: it has been estimated that 8.7% of young people live with HIV. Within primarily US and UK contexts, there has been much debate over the relative merits of abstinence-only and comprehensive sexual education programmes. These perspectives have largely been presented as irreconcilable, but…

Background: We describe the prevalence of behaviors that put American Indian and Alaska Native (AI/AN) high school students at risk for teen pregnancy and sexually transmitted infections (STIs) and the relationships among race/ethnicity and these behaviors. Methods: We analyzed merged 2007 and 2009 data from the national Youth Risk Behavior…
