El Kadiri Boutchich, Driss – Journal of Education, 2019
The alternative human capital evaluation method proposed is implemented via two methods: principal component analysis and discriminant analysis. The first method classifies the research laboratory activities in homogeneous clusters, while the second method standardizes their scores. The proposed method is sitting in the activity-based management…

Bodzewski, Kentaro Y.; Caylor, Ryan L.; Comstock, Ashley M.; Hadley, Austin T.; Imholt, Felisha M.; Kirwan, Kory D.; Oyama, Kira S.; Wise, Matthew E. – Journal of Chemical Education, 2016
A differential scanning calorimeter was used to study homogeneous nucleation of ice from micron-sized aqueous ammonium sulfate aerosol particles. It is important to understand the conditions at which these particles nucleate ice because of their connection to cirrus cloud formation. Additionally, the concept of freezing point depression, a topic…

Johnston, Meghan R.; Makriyannis, Alexandros; Whitten, Kyle M.; Drew, Olivia C.; Best, Fiona A. – Journal of Chemical Education, 2016
In order to introduce the concepts of biocatalysis and its utility in synthesis to organic chemistry students, a multistep synthesis of endogenous cannabinergic ligand 2-arachidonoylglycerol (2-AG) was tailored for use as a laboratory exercise. Over four weeks, students successfully produced 2-AG, purifying and characterizing products at each…

Weers, Paul M. M.; Prenner, Elmar J.; Curic, Spomenka; Lohmeier-Vogel, Elke M. – Biochemistry and Molecular Biology Education, 2016
The laboratory protocol presented here takes about 3 hours to perform and investigates protein and lipid interactions. Students first purify His6-tagged human apolipoprotein A-I (apoA-I) with Ni-NTA affinity resin in a simple batch protocol and prepare multilamellar vesicles (MLV) from pre-dried phospholipid films. When apoA-I is added to the MLV,…

Efstathiou, Charalampos; Hovardas, Tasos; Xenofontos, Nikoletta A.; Zacharia, Zacharias C.; deJong, Ton; Anjewierden, Anjo; van Riesen, Siswa A. N. – Educational Technology Research and Development, 2018
The present study employed a quasi-experimental design to assess a computer-based tool, which was intended to scaffold the task of designing experiments when using a virtual lab for the process of experimentation. In particular, we assessed the impact of this tool on primary school students' cognitive processes and inquiry skills before and after…

Coleman, Aaron B.; Lorenzo, Kyla; McLamb, Flannery; Sanku, Abhiraj; Khan, Sahil; Bozinovic, Goran – Biochemistry and Molecular Biology Education, 2023
Effectively teaching scientific reasoning requires an understanding of the challenges students face when learning these skills. We designed an assessment that measures undergraduate student abilities to form hypotheses, design experiments, and interpret data from experiments in cellular and molecular biology. The assessment uses…

Güler, Maside; Ünal, Suat – Research in Science & Technological Education, 2023
Background: Achieving the targeted of university physics courses and improving student motivation requires varying types of instructional design. One alternative approach to the traditional lecture format involves the use of historical science stories, which are narratives that present episodes from the life of a scientist, as well as…

J. C. – Anatomical Sciences Education, 2023
Historically, Anatomy education is an in-person discipline involving exposure to human body donors that facilitates personal and professional growth through, in part, the initiation of reflection on the topic of death. However, during the COVID-19 pandemic the decreased exposure to cadaveric anatomy for many health professions students may have…

Frydenberg, Mark – Information Systems Education Journal, 2023
The Internet of Things (IoT) is a network of objects that can exchange data with other devices also connected to the Internet. One of the most common consumer examples of IoT is home automation, as a variety of smart devices, including doorbells, lightbulbs, thermostats, and refrigerators are now available which users can control remotely using…

Onyeaka, Helen; Passaretti, Paolo; Miri, Taghi; Hart, Abarasi; Favero, Claudia; Anumudu, Christian K.; Robbins, Phillip – Biochemistry and Molecular Biology Education, 2023
The limited capabilities of teaching laboratories, combined with an increasing number of students enrolled in university, require constant augmentation of instructional approaches. By enhancing laboratory demonstrations with digital technology, these structural issues can be addressed while at the same time enhancing student understanding and…

Piccolo, Alessandra Lo; Mingrino, Marta – Research on Education and Media, 2023
The social, cultural and economic changes of this century have inevitably also affected the world of education and training, which, therefore, have renewed paths, objectives and goals. Internalised knowledge must be re-used creatively in a new context. 'Knowing' becomes 'knowing how' and then 'knowing how to be'. Learning is lifelong and is…

Cale, Andrew S.; Byram, Jessica N.; Organ, Jason M.; Schmalz, Naomi A. – Anatomical Sciences Education, 2023
The Center for Anatomy and Physiology Education has hosted interactive human cadaver laboratory tours for local high schools (ages 14-18) and undergraduate university students since 2014 to expose students to healthcare careers. Students receive information on the history of body donation and healthcare careers and observe human anatomy on…

Saribas, Deniz – International Journal of Science Education, 2023
The reform documents point out the necessity of teaching the plurality of scientific method (SM) when scientists engage in scientific practices (SPs). The dramatic change in education due to COVID-19 pandemic necessitates examining the outcomes of online education, especially laboratory applications courses, which the students and educators used…

Rosen, Drew; Kelly, Angela M. – International Journal of STEM Education, 2023
Background: While laboratory practices have traditionally been conducted in-person, online asynchronous laboratory learning has been growing in popularity due to increased enrollments and the recent pandemic, creating opportunities for accessibility. In remote asynchronous learning environments, students have more autonomy to choose how they…

Mercado, Justine C.; Picardal, Jay P. – Science Education International, 2023
In biotechnology education, practical laboratory courses are vital. In having these practical courses, a lot of time and monetary resources are needed, it also requires the presence of the teacher and students and all the necessary equipment, which is currently not allowed in the Philippines due to the pandemic restrictions. Biotech virtual…
