Mason, Kevin; Schieffer, Steve; Rose, Tara; Matthias, Greg – Science Teacher, 2022
A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

Daniela De Luchi; Renato Bonomi – Journal of Chemical Education, 2023
Scientists have always been fascinated by transient far-from-equilibrium systems. Since the (early) 1970s, there have been literature reports on the implementation of didactic experiments as a tool for attracting and stimulating students' and general public interest. In this work, a group of 12 high school students, supported by their chemistry…

Abby L. Manning; Bryanna N. Roos; Amber Flynn Charlebois; Kelly Hutchinson-Anderson; Stephen G. Tajc – Journal of Chemical Education, 2023
In an effort to further develop critical thinking and problem solving skills, a guided-inquiry-based, multioutcome organic chemistry synthesis and characterization experiment was developed. Students were provided with the protocol for a time-saving microwave-assisted acetanilide synthesis reaction from acetic anhydride and an unknown primary aryl…

Alexander Grushow – Journal of Chemical Education, 2022
A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students' connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto-enol tautomerization of 2,4-pentanedione. However, unlike…

Niu Huang; Chao Li; Shili Gan; Cancan Le; Huan Liu; Wei Liu; Liqun Ye – Journal of Chemical Education, 2022
With the benefits of low cost, energy efficiency, and environmental protection, photocatalytic hydrogen production is considered to be the most promising technology for the development of a clean and sustainable society. However, the utilization of photocatalytically generated hydrogen is not very common yet. Therefore, tertiary education urgently…

Perera, Viveka; Acharya, Baku; Patrick, Amanda L.; Mlsna, Deb – Journal of Chemical Education, 2020
Mass spectrometers are ever-increasingly powerful, user-friendly, and affordable. Thus, the addition of mass spectrometry experiments into the undergraduate laboratory curriculum is now both feasible and an effective tool to introduce students to relevant instrumentation. Here an experiment demonstrating the use of a high-resolution electrospray…

Patel, Parth H.; Conrad, Kristofer L.; Pathiranage, Anuradha L.; Hiatt, Leslie A. – Journal of Chemical Education, 2020
Given student familiarity with electronic cigarettes (e-cigs), this lab uses a student-built smoke collection apparatus to collect e-cig vapors to teach students about gas chromatography-mass spectrometry (GC-MS). Students in a second semester, introductory organic chemistry course spent 1 week collecting e-cig vapors and 1 week qualitatively…

Agustian, Hendra Y. – Chemistry Education Research and Practice, 2022
This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

George-Williams, Stephen R.; Ziebell, Angela L.; Thompson, Christopher D.; Overton, Tina L. – International Journal of Science Education, 2020
Previous work at Monash University has shown that students recognise that inquiry-, problem-, context- and industry-based experiments were better contextualised, more open to decision making and aided in the development of scientific and transferable skills. This study investigated whether these gains persisted over a longer time scale, rather…

Parreira, Pedro; Yao, Eric – Physics Education, 2018
Being able to contextualise and solve complex problems is a highly valued skill in STEM graduates--a skill which we strive to nurture in our students. Since its introduction into undergraduate teaching, laboratory teaching has been used to consolidate students conceptual understanding, develop their practical skills and inculcate an evidence based…

Sujarittham, Thanida; Tanamatayarat, Jintawat; Kittiravechote, Aungtinee – Turkish Online Journal of Educational Technology - TOJET, 2019
The goals of this advanced physics laboratory course emphasized not only to improve students' physics knowledge but also spectrum scientific abilities in particular for preparing their future-ready competencies. One of those scientific abilities was initiated to study that was "the ability to design experiment". It was the fundamental…

Pérez-Álvarez, Leyre; Ruiz-Rubio, Leire; Vilas-Vilela, Jose Luis – Journal of Chemical Education, 2018
To enhance critical thinking and problem-solving skills, a project-based learning (PBL) approach for "Instrumental Techniques" courses in undergraduate physical chemistry was specifically developed for a pharmacy bachelor degree program. The starting point of this PBL was an open-ended question that is close to the student scientist's…

Albright, Jessica C.; Beussman, Douglas J. – Journal of Chemical Education, 2017
Capillary electrophoresis is an important analytical separation method used to study a wide variety of samples, including those of biological origin. Capillary electrophoresis may be covered in the classroom, especially in advanced analytical courses, and while many students are exposed to gel electrophoresis in biology or biochemistry…

Duarte, Rita C. C.; Ribeiro, M. Gabriela T. C.; Machado, Adelio A. S. C. – Journal of Chemical Education, 2017
The different ways microscale and green chemistry allow reducing the deleterious impacts of chemistry on human health and the environment are discussed in terms of their different basic paradigms: green chemistry follows the ecologic paradigm and microscale the risk paradigm. A study of the synthesis of 1-bromobutane at macro- ? microscale (109.3…

Davis, Eric J.; Pauls, Steve; Dick, Jonathan – Journal of Chemical Education, 2017
Presented is a project-based learning (PBL) laboratory approach for an upper-division environmental chemistry or quantitative analysis course. In this work, a combined laboratory class of 11 environmental chemistry students developed a method based on published EPA methods for the extraction of dichlorodiphenyltrichloroethane (DDT) and its…
