Gorman, Stephen A.; Holmes, Kimberly; Brooke, Gemma; Pask, Christopher M.; Mistry, Nimesh – Journal of Chemical Education, 2021
A traditional laboratory course with the primary learning outcome of improving students' theoretical knowledge has received much criticism over the years due to the lack of evidence that these goals have achieved. We report our efforts to redesign a traditional first-year organic and inorganic (also known as synthetic) laboratory course from…

Sarah Ritter; Liza Abraham – Journal of Chemical Education, 2022
This project introduces green chemistry to the undergraduate laboratory through two pedagogical techniques: undergraduate research and guided-inquiry. Through these two learning activities, an efficient synthetic procedure for the PRINS cyclization of citronellal into isopulegol, focused on minimizing negative environmental impact, was developed.…

Hilal Coskun Karabulut; Naime Elcan kaynak; Ishak Afsin Kariper – Research in Science & Technological Education, 2024
This paper examines the findings obtained in a chemistry laboratory course provided through online hands-on activities during the pandemic. Case study design, one of the qualitative research methods, was used. The data collection period was 8 weeks. The study was carried out with 16 third-year pre-service science teachers within the scope of a…

Hands-on experiences in analytical chemistry laboratories are essential to improve students' technical skills on handling analytical glassware and instruments, but the coronavirus pandemic in 2020-2021 disrupted such learning activities. Thus, alternative remote activities are required to supplement practical skills. In this work, a new portable…

Barnett, Kerry L.; Shea, Kevin M.; McGeough, Catherine; Trotta, Kristine; Williams, Steven; Ly, Minh; Aloisio, Kathryn – Journal of Chemical Education, 2020
A semester-long research project for second-semester organic chemistry lab sections was developed. Student projects were based on preliminary data from faculty research that suggested the natural product neurolenin B to be a treatment for lymphatic filariasis. Students isolated neurolenins from the Central American plant "Neurolaena…

Sandi-Urena, Santiago – Journal of Chemical Education, 2020
Three days into the academic year, the COVID-19 pandemic abruptly led to emergency remote teaching, ERT, of Chemical Experimentation--a revised alternative to the majors' General Chemistry Laboratory at the University of Costa Rica. The course was reoriented to support students' development of nontechnical experimentation skills and scientific…

Davy, Emma C.; Quane, Steven L. – Journal of Chemical Education, 2021
Lab-based learning is an essential part of any undergraduate chemistry curriculum as it incorporates necessary and required hands-on experiential learning. However, in response to the COVID-19 pandemic, many students are learning from home, rendering laboratory instruction a particular challenge. Options for educators include third party virtual…

Karpudewan, Mageswary; Mathanasegaran, Kumareson – Asia-Pacific Forum on Science Learning and Teaching, 2018
The abstractness of certain chemistry concepts demands the use of appropriate teaching strategies to enable students to construct mental images of the concepts. The concepts include understanding the effects of concentration and catalyst on the rate of reaction. The reactions at the molecular level are not visible to human eyes and the use of…

Gross, Katharina; Harmer, Sandra Pia – Online Submission, 2020
In the course of PISA and TIMSS a lot of out-of-school lab days have been established; as non-formal extracurricular learning environments they shall provide an efficient addition to formal learning at school. The "ELKE" project is a non-formal extracurricular learning lab that aims at linking curricular content and competence-centred…

Gross, Katharina; Pawlak, Felix – Online Submission, 2020
The use of ICT in science education offers many opportunities to promote students' learning and experimenting comprehensively. Considering that, it is important not simply to replace traditional media, but to explicitly identify the added value of ICT tools for students and teachers. Especially alternative forms of documenting experiments,…

Yamashita, Shuichi; Kashiwaguma, Yasuyuki; Hayashi, Hideko; Pietzner, Verena – Science Education International, 2017
In science classes, students usually learn about the law of definite proportions by the oxidation of copper. However, common procedures usually do not lead to proper results. This leads to confusion among the students because their experimental results do not fit to the theoretical values. Therefore, we invented a new procedure for this experiment…
