Most constructionist efforts have focused on supporting learners with tools for designing with digital and/or physical media. Recent developments in life sciences now allow K‐12 learners to design ...with living materials, or to biodesign. In this paper, we report on the development of a biodesign studio activity called biocakes wherein teams of high school youth genetically modified a yeast strain to bake a nutrient fortified food product. Using a qualitative deductive analysis of classroom observations, interviews and projects, we examined high school youth experiences and reflections of these activities to answer three research questions: (1) What kind of artefacts did youth make with living media? (2) How did youth engage in biodesign? and (3) What did youth have to say about their biodesign experiences? We discuss how our analyses of biodesign applications highlight the importance of assembly practices, social engagement and imaginative design for constructionist learning. These insights provide compelling examples for designing with living media in K‐12 education.
Practitioner notes
What is already known about this topic?
Constructionist perspectives shape important ideas about what we know about science learning, and notably in computer science fields.
One widely taken up example includes making, where learners use crafts to make interactive computational objects.
In life science, constructionism also provides insights about learning using digital media to model biological systems or interact with living materials.
What this paper adds?
This paper extends these perspectives by examining production and engagement when learners construct with living materials—an approach that has only recently been possible with the development of accessible wet lab tools.
We frame learning activities as a studio model—that emphasised application design, iteration and critique—to better assess the roles assembly, construction and speculative design play in production that uses living materials.
Our findings suggest that assembly is important for creating accessible points of entry to complex biological fabrication processes.
We also find that speculative design provides an opportunity for learners to extend their existing abilities beyond what is otherwise available given their expertise or access to resources, and thus expansively explore related ideas.
Implications for practice and/or policy
Assembly and speculative design have important places in constructionist‐driven production with living materials and could, therefore, be leveraged in practice.
The purpose of this study was to investigate the effect of augmented reality (AR) using a 3D app in a smartphone on students' learning outcomes and satisfaction in teaching angle measurement error to ...vocational high school students with different spatial ability. A quasi-experimental pretest/posttest was employed. There were 197 students from three vocational high schools in the southern, northern, and eastern part of Taiwan participated in this study. To minimize the biased result, we established one control group and one experimental group in each school. The experimental group used multimedia teaching tools and AR technology as a supplement, while the control group was taught by multimedia teaching tools only. We assessed some factors that possibly affect the learning outcomes and learning satisfaction, including different spatial abilities and different digital materials as teaching tools. Our finding highlights that different teaching materials influence students' learning outcomes and satisfaction, whereas spatial ability does not affect. Further discussion and implementation are also identified in this study.
Although non-consensual sexting seems to concern not only adults but also middle adolescent students, with detrimental consequences on their well-being, the related research-based effective school ...prevention programs are almost absent. Furthermore, there is an unanswered research question as to whether sex-related issues, such as sexual preoccupation, matters in adolescents’ non-consensual sexting and its prevention. The present study investigated the effectiveness of a school-based intervention against non-consensual sexting among middle adolescents, based on the European funded program TABBY (Threat Assessment of Bullying Behavior in Youth). Furthermore, the predictive role of sexual preoccupation was examined. Overall, 280 Greek students from randomly selected junior high school responded to self-report scales on non-consensual sexting and sexual preoccupation. Based on an experimental longitudinal research design, only the experimental ( N = 131), but not the control group of students ( N = 149), participated in the intervention. To test the effectiveness of the intervention, both student groups completed the scales before (1st phase), immediately after (2nd phase), and six months after the intervention (3rd phase), which was implemented by trained teachers. The results showed both, the short-term and long-term effectiveness of the intervention. Also, the study highlighted the significant contribution of sexual preoccupation awareness in reducing non-consensual sexting, especially immediately after and six months after the intervention. The study implies the necessity to adapt existed prevention programs to the specific parameters of non-consensual sexting, integrating at the same time sexual preoccupation awareness activities to better address this issue.
College students may be vulnerable to food insecurity due to limited financial resources, decreased buying power of federal aid, and rising costs of tuition, housing, and food. This study assessed ...the prevalence of food insecurity and its sociodemographic, health, academic, and food pantry correlates among first-year college students in the United States.
A cross-sectional study was conducted among first-year students (n = 855) across eight U.S. universities. Food security status was assessed using the U.S. Department of Agriculture Adult Food Security Survey Module. Cohen's Perceived Stress Scale, Pittsburgh Sleep Quality Index, and Eating Attitudes Test-26 were used to assess perceived stress, sleep quality, and disordered eating behaviors, respectively. Participants self-reported their grade point average (GPA) and completed questions related to meal plan enrollment and utilization of on-campus food pantries.
Of participating students, 19% were food-insecure, and an additional 25.3% were at risk of food insecurity. Students who identified as a racial minority, lived off-campus, received a Pell grant, reported a parental education of high school or less, and did not participate in a meal plan were more likely to be food-insecure. Multivariate logistic regression models adjusted for sociodemographic characteristics and meal plan enrollment indicated that food-insecure students had significantly higher odds of poor sleep quality (OR = 2.32, 95% CI: 1.43-3.76), high stress (OR = 4.65, 95% CI: 2.66-8.11), disordered eating behaviors (OR = 2.49, 95% CI: 1.20-4.90), and a GPA < 3.0 (OR = 1.91, 95% CI: 1.19-3.07) compared to food-secure students. Finally, while half of the students (56.4%) with an on-campus pantry were aware of its existence, only 22.2% of food-insecure students endorsed utilizing the pantry for food acquisition.
Food insecurity among first-year college students is highly prevalent and has implications for academic performance and health outcomes. Higher education institutions should screen for food insecurity and implement policy and programmatic initiatives to promote a healthier college experience. Campus food pantries may be useful as short-term relief; however, its limited use by students suggest the need for additional solutions with a rights-based approach to food insecurity.

Neste texto trazemos uma síntese histórica das inciativas de políticas educacionais que envolveram o ensino médio brasileiro, com ênfase para as que implicaram em algum grau de reformulação ...curricular. O período delimitado para análise compreende desde a aprovação da Lei de Diretrizes e Bases da Educação de 1996 até o presente momento. É conferida ênfase à atual reforma, que passou a ser conhecida como Novo Ensino Médio. São analisados documentos normativos dos poderes legislativo e executivo, que compõem um conjunto de políticas curriculares nem sempre convergentes entre si, além de programas ou ações do poder executivo federal. Para efeitos de interpretação do material coligido e analisado é considerado o contexto de expansão do acesso à etapa final da educação básica. Dentre as conclusões são destacadas evidências de um período de intensas disputas em torno dos sentidos, finalidades e modo de organização do ensino médio no Brasil.
Este artigo tem como objetivo trazer reflexões sobre a reforma educacional de 2017 denominada Novo Ensino Médio (NEM) e seu impacto na realização do Exame Nacional do Ensino Médio (ENEM) 2023, ...destacando-se o tema da prova de redação que coloca em pauta a invisibilização do trabalho da mulher. Esta discussão se dá em diálogo com o pensamento de Sílvia Federici e María Lugones. A partir disso, o trabalho traz uma análise do NEM no que se refere à formação da juventude brasileira e segue apresentando o Ensino Técnico de Nível Médio Integrado (EMI) como uma possibilidade para a reconstrução deste nível de ensino, respeitando-se parâmetros como formação integral de jovens, escolarização integrada – formação profissional e formação geral – e escola de tempo integral, tríade que sustenta um ensino médio comprometido com a justiça social e a democracia. Por fim, delineia-se como se pensa o EMI no Instituto Federal de São Paulo (IFSP) – Campus Registro com ênfase à resistência dos docentes ao não aceitarem a reformulação dos cursos técnicos de nível médio na forma integrada baseada no NEM. Para tais fins, buscou-se o apoio de discussões teórico-filosóficas propostas por autores como Marcos Antônio Lorieri, Gaudêncio Frigotto, Marise Ramos, além da análise de notícias e documentos do IFSP.
High school equivalency (HSE) is a recognised alternative to a high school diploma in the United States. It offers an opportunity to a range of disadvantaged adult learners such as school dropouts, ...refugees etc. to attain an educational certificate enabling them to move on in their life. This article presents an autoethnographic case study of a non-profit HSE programme in Philadelphia during the COVID-19 pandemic. The four authors of this article, all of them instructors on the front line of the youth crisis in adult education, explore the broader context of non-governmental organisation (NGO) management and privatised HSE exams. In their research and their reflections, they found that the pandemic exacerbated existing economic and social inequalities, with both pre-pandemic and current delivery of their HSE programme failing to address the survival needs of a population which has long been living in crisis. Juxtaposing relevant youth-in-crisis literature with narratives both from before the pandemic and whilst living through it, the authors of this article discuss the funding and institutional constraints around the environment in which they teach. Their case study sheds light on competing priorities within the non-profit education landscape, highlighting both pitfalls and successes in HSE curriculum and administration. The authors conclude that rapid adaptation to online teaching tools, platforms and products is not the panacea that many outcomes generators would like it to be.
Damage to the natural environment (floods, pollution) and social (decreased manners) becomes the focus of education to reduce its bad impact. Prevention of damage to the natural environment through ...learning biology, but the application of environmental education through religious subjects, so that the two curricula are expected to synergize with each other to protect the environment and harmonization of social life. This study aims to analyze the environmental education content in the Islamic religious education curriculum using content analysis. The results showed that the environmental education content in the Islamic religious education curriculum was taught in grades I, II, III, IV, VI, VII, IX, XI, and XII. Environmental Education in the Islamic Religious Education Curriculum includes humans as social beings, natural resources, personal hygiene, and the environment. Implementation of attitudes that arise include courtesy and mutual respect, clean and healthy living, and slaughtering sacrificial animals wisely.

What is the best education for exceptionally able and high-achieving youngsters? Can the United States strengthen its future intellectual leadership, economic vitality, and scientific prowess without ...sacrificing equal opportunity? There are no easy answers but, as Chester Finn and Jessica Hockett show, for more than 100,000 students each year, the solution is to enroll in an academically selective public high school.Exam Schoolsis the first-ever close-up look at this small, sometimes controversial, yet crucial segment of American public education. This groundbreaking book discusses how these schools work--and their critical role in nurturing the country's brightest students.
The 165 schools identified by Finn and Hockett are located in thirty states, plus the District of Columbia. While some are world renowned, such as Boston Latin and Bronx Science, others are known only in their own communities. The authors survey the schools on issues ranging from admissions and student diversity to teacher selection. They probe sources of political support, curriculum, instructional styles, educational effectiveness, and institutional autonomy. Some of their findings are surprising: Los Angeles, for example, has no "exam schools" while New York City has dozens. Asian-American students are overrepresented--but so are African-American pupils. Culminating with in-depth profiles of eleven exam schools and thoughtful reflection on policy implications, Finn and Hockett ultimately consider whether the country would be better off with more such schools.
At a time of keen attention to the faltering education system,Exam Schoolssheds positive light on a group of schools that could well provide a transformative roadmap for many of America's children.
