Mariur Rodriguez Moreno; Nye C. Johnson; Christopher B. Stewart; Mary L. Setelin; Adam X. Wayment; Braxton M. Felix; Scott R. Burt; David J. Michaelis – Journal of Chemical Education, 2024
We describe a three-day advanced organic laboratory experience that includes the solid-phase synthesis of an unknown three amino acid polypeptide for junior/senior undergraduate chemistry majors. Students conduct a series of 1D and 2D NMR experiments (HSQC, HMBC, TOCSY) and analyze the data to identify the side chain residues of the peptide and…

Leyla Ayverdi; Derya Girgin; Ismail Satmaz; Eylem Yalçinkaya Önder – Journal of Interdisciplinary Studies in Education, 2025
This study employed a mixed-methods design to investigate the impact of activities developed by the Ministry of National Education (MoNE) on the scientific creativity and scientist perceptions of gifted 5th-grade students. The research used a one-group pretest-posttest design with a sample of 22 students from a Science and Art Education Centre in…

Winona Y. Diola; Joel B. Jalon Jr.; Maricar S. Prudente – Anatolian Journal of Education, 2025
While previous research has shown that claim-evidence-reasoning can effectively promote higher-order thinking skills in science education, more research should be done on using claim evidence-reasoning in elementary school settings. This study aims to investigate the effectiveness of claim-evidence-reasoning in promoting the scientific reasoning…

Andrew F. Mashintonio; Richard H. Heineman – Journal of Microbiology & Biology Education, 2025
Course-based undergraduate research experiences (CUREs) have grown in popularity, particularly within introductory biology courses, to provide more students with authentic research experiences. CUREs have been shown to have many of the same positive effects as conventional research experiences; however, most assessments of CUREs lack an…

Angelica Acevedo Guanzon – ProQuest LLC, 2024
This study thoroughly explores the relationships between the challenges faced by students and the alternative problem-solving strategies employed. By analyzing these connections, the research aims to offer a comprehensive understanding of how students address difficulties in science learning and the adaptive strategies they apply. Through this…

Pamela Medina; Waldo Quiroz – Journal of Biological Education, 2025
Within the scope of this investigation, educational instruments grounded on materialist ontology were employed to undertake a semantic analysis of the concepts of cell and the mechanisms of living organisms as they appear in biology and natural science textbooks. Drawing upon the ontological categories applied to distinct biological system levels,…

Mary F. Johnston; Valarie L. Akerson – International Journal of Research in Education and Science, 2025
This action research case study explored the ability of three high school chemistry students to grow in their understanding of nature of science (NOS) during its explicit-reflective inclusion in two unit chapters on bonding (ionic compounds followed by covalent molecules). Students completed a pre, post and delayed Views of Nature of Science Form…

Jorge Pozuelo-Muñoz; Esther Cascarosa-Salillas; Esther Alonso; Carmen Barba – Research in Science Education, 2025
Every three years, the Organisation for European Cooperation and Development evaluates the scientific competence of European students. Recent results have demonstrated that scientific competence in Spain is somewhat underdeveloped, which underscores the need to apply educational methodologies that favour the development of said competence. This…

Plant extracts and their components have been reported to have antimicrobial properties against phytopathogens. Although such properties could be harnessed for the development of new pathogen control strategies, there are no standardised methods for their assessment in different extracts. The laboratory exercise presented here involves the use of…
