Oliver B. Andrew; James Sherwood; Glenn A. Hurst – Journal of Chemical Education, 2022
A laboratory experiment was developed to introduce systems thinking and green chemistry concepts through the synthesis of the antidepressant and smoking cessation aid, bupropion hydrochloride. The traditional synthesis has several issues from a green chemistry perspective: it uses the toxic solvents N-methylpyrrolidinone (NMP) and dichloromethane…

Larissa Wellhöfer; Arnim Lühken – Journal of Chemical Education, 2022
The focus in teaching and research is shifting from a traditional perspective of information literacy (IL) as a specific set of general, mostly text-based skills to a more comprehensive understanding of the complex aspects that constitute IL as an ongoing, context-specific process. However, there is a need for further insight into the social and…

Chatchadaporn Pinthong; Pimchai Chaiyen; Somchart Maenpuen; Pirom Chenprakhon – Journal of Chemical Education, 2022
This research developed learning activities for students to explore and connect the concepts of acid-base titration, equivalence points, pK[subscript a], and molar absorption coefficients. Polyphenolic compounds consisting of p-coumaric acid (CMA), caffeic acid (CFA), and 3,4,5-trihydroxycinnamic acid (3,4,5-THCA) were selected as study models.…

Luke A. Wilczek; Alannah J. Clarke; Maria del Carmen Guerrero Martinez; Jesse B. Morin – Journal of Chemical Education, 2022
To remain globally competitive, education in the United States must focus on retaining students in science, technology, engineering, and mathematics (STEM). As laboratory courses have the potential to be powerful attractors or deterrents to a field, developing effective laboratory pedagogies is important to retain students in STEM. A course-based…

Elizabeth Ragland; Elizabeth L. Karcher – NACTA Journal, 2022
Inquiry-based learning (IBL) is a student-centered teaching technique that promotes engagement through higher-order thinking, collaboration, and creativity. This study examines the impact of IBL levels on students' interest, motivation, and engagement. Three levels of IBL (traditional, structured, and guided) were implemented in an introductory…

Odom, Arthur L.; Bell, Clare V. – Science Teacher, 2019
In 1827, Robert Brown noticed pollen suspended in water bouncing around erratically. It wasn't until 1905 that Albert Einstein provided an acceptable explanation of the phenomenon (Kac 1947): Brownian motion is the random movement of particles (e.g., pollen) in a fluid (liquid or gas) as a result of collisions with atoms and molecules. Movement of…

Kovacic, Marin; Ašperger, Danijela – Journal of Chemical Education, 2019
A low-cost turbidimeter, colorimeter, and nephelometer (TCN) multipurpose instrument applicable for undergraduate, graduate, and research laboratories is demonstrated within this work. The instrument relies on simple and robust electronics while using a PC sound card as an analog-to-digital converter. The performance of the instrument was…

Love, Tyler S. – Technology and Engineering Teacher, 2019
Technology and Engineering (T&E) education has traditionally included safety as a core component of its curriculum and instruction. Recommendations for safety instruction can be found in manual arts and industrial arts documents (Christy, 1938). Safety was emphasized across all grade levels, including the elementary grades (Miller & Boyd,…

Wu, Ting; Albion, Peter – Educational Technology & Society, 2019
Facing calls for greater emphasis on STEM education in primary school classrooms, teachers may be anxious because of limited exposure to STEM in their own education. The Australian Curriculum: Technologies is new and many teachers are not familiar with its content. Hence both in-service and pre-service teachers (PSTs) require preparation. This…

Danielle A. Guarracino; Joseph L. Baker; J. Lynn Gazley – Journal of College Science Teaching, 2025
Having a deeper understanding of molecules in their structural forms allows students to grasp biochemical and general chemical concepts in a more profound manner. Through the use of visualization software, we have shown that students gain confidence and insight into the chemical workings of molecular structure and can then utilize this knowledge…

Bijoy Kumar Upadhyaya; Apurba Saha; Pijush Kanti Dutta Pramanik – Turkish Online Journal of Distance Education, 2025
The COVID-19 pandemic has put the entire world in a very challenging situation, and similar to other sectors, education has also been severely affected. The teaching-learning process during that period was carried out only online. As none of the stakeholders expected such an unprecedented situation, all the institutions had to switch to an online…

Rikke Toft Nørgård; Kim Holflod – Educational Philosophy and Theory, 2025
This paper explores quadruple helix ecosystems, cultural hubs, and living labs as models for transformative partnerships for higher education institutions (HEIs) as they move towards more open, co-operative, and co-creative research and innovation formats for public good. The transition of HEIs from mode 2 to mode 3 institutions prompts a cultural…

Michal Sigron; Dorothy Langley; Stanislaw Dylak; Edit Yerushalmi – Physical Review Physics Education Research, 2025
Response to the continuing call to integrate scientific inquiry activities into high school education has taken different forms varying in student ownership, physical setting, time span, and mentoring resources. Important issues are how students perceive central dimensions of their experience, and the extent to which the inquiry framework design…

Xin Deng; Nuoya Ma; Xinwen Hu; Yong Li; Junyu He; Guoying Zou – Biochemistry and Molecular Biology Education, 2025
The knowledge of "clinical molecular biology testing technology" is complex, conceptual expressions are abstract and difficult to understand, and the student's interest in learning is low. This study aimed to evaluate the effectiveness of a cyclic teaching method based on case analysis combined with an exploratory teaching method using…
