Liu, Li; Ling, Yizhou; Yu, Jing; Fu, Qiang – Journal of Chemical Education, 2021
This study developed a complexometric titration simulation program based on LabVIEW. With built-in approximation and rigorous algorithms, the program can easily simulate and plot a single or a group of complexometric titration curves. On the basis of this program, we developed and implemented an online course to guide undergraduates to (i) compare…

Stefaniak, Kristina R.; Winfrey, Merrie K.; Curtis, Anna C.; Kennedy, Sarah A. – Journal of Chemical Education, 2021
General chemistry laboratory curriculum reform is underway at a midsized state university through a collaborative, inclusive, and iterative approach. Using a backward design approach, faculty collaborated to actualize a shared vision, define laboratory learning objectives, and outline considerations for inclusivity during summer workshops that…

Howitz, William J.; McKnelly, Kate J.; Link, Renée D. – Journal of Chemical Education, 2021
Large, multisection laboratory courses are particularly challenging when managing grading with as many as 35 teaching assistants (TAs). Traditional grading systems using point-based rubrics lead to significant variations in how individual TAs grade, which necessitates the use of curving across laboratory sections. Final grade uncertainty…

Chiang, Chih-Yun; Huang, Hsin-Wei; Chen, Shao-Yen; Chen, Yun-An; Chang, Yuan-Mou; Huang, Hao-Jen – Biochemistry and Molecular Biology Education, 2021
Volatile-mediated impacts of microbes on plants have aroused interest among scientists in the life science field. This study describes an inquiry-based laboratory module named "Microbial Talk", which related to microbial volatile-mediated communication, including the process of design, implementation, and assessment. First-year biology…

Monsurat M. Lawal; Tugba G. Kucukkal – Journal of Chemical Education, 2024
An undergraduate-level Computational Chemistry project was incorporated initially into a Physical Chemistry course and then into the laboratory curriculum in the subsequent application. Before the introduction of the project, the lectures covered quantum chemistry, spectroscopy, and kinetics while simultaneously including computational chemistry…

Wiseman, Emily; Carroll, David J.; Fowler, Samantha R.; Guisbert, Eric – Journal of the Scholarship of Teaching and Learning, 2020
The advantages of active learning approaches have prompted national recommendations for the development of inquiry-based laboratories to replace traditional laboratory classes. However, there is little consensus for the most-effective implementation strategies. Frequently, a single inquiry-based exercise is incorporated at the end of a traditional…

Koeper, Ingo; Shapter, Joe; North, Vanessa; Houston, Don – Journal of University Teaching and Learning Practice, 2020
In science courses in general, but especially in first year chemistry classes, the amount of content that is delivered is often overwhelming and too complex for the student to easily cope with. Students not only have to gain knowledge in a variety of different fields, they also have to learn new laboratory skills and analytical techniques.…

Wheeler, Lindsay B.; Clark, Charles P.; Grisham, Charles M. – Journal of Chemical Education, 2017
Laboratory course redesign and effective implementation of an inquiry-based curriculum can be challenging, particularly when teaching assistants (TAs) are responsible for instruction. Our multiyear redesign of a traditional general chemistry laboratory course has included transitioning to a project based guided inquiry (PBGI) curriculum that…

Nguyen, Van Bien; Vylaychit, Xayparseut; Nguyen, Anh Thuan – Online Submission, 2019
How to help teachers to design teaching plan for raising student's competency at secondary school in Laos is now of great concern. On the other hand, teachers teach sciences almost by lecturing theoretical only. They rarely explain the problems based on actual phenomena that occur in pupils' daily life nor do experiment during the class. Thus, one…

Cipková, Elena; Karolcík, Štefan; Dudová, Natália; Nagyová, Sona – Curriculum Journal, 2018
Decreasing interest in Science among students, confirmed by several investigations, calls for the need to revise the contents of the curricula for Science subjects, including Biology. Modern Biology curricula should not only contain key biological concepts but also provide a teacher with sufficient space to develop students' competencies of…

Kerstiens, Geri Anne – ProQuest LLC, 2019
Recently, there have been many calls for an increase in instruction on the nature of science (NOS) in schools (i.e. NRC, 1996; NGSS Lead States, 2013). These calls recognize the importance of this topic at all levels of science education, but there is little guidance in terms of how to address it effectively in curricula. Similarly, there have…

Brookes, David T.; Ektina, Eugenia; Planinsic, Gorazd – Physical Review Physics Education Research, 2020
[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] This paper discusses the theoretical framework and curriculum materials that form the basis of the Investigative Science Learning Environment (ISLE) approach to learning and teaching physics. ISLE, as a philosophical approach to learning, has two core…

Kim, Sun Young; Hamdan Alghamdi, Amani K. – International Journal of Science and Mathematics Education, 2019
This mixed methods study explored how Saudi Arabia's science education reform is functioning in 2 public girls' secondary schools located in Dammam, 1 of the main cities in Saudi Arabia. Saudi Arabia recently launched a new initiative to promote science education innovation by providing science curriculum change, professional development for…

Boltax, Ariana L.; Kosinski-Collins, Melissa S.; Pontrello, Jason K. – Journal of College Science Teaching, 2016
This article describes the development of a model for an optional, research-based course that bridges two existing, traditionally separate, introductory science courses. This research course provided freedom for students to design and implement new experiments on the basis of technical foundations built from enrollment in separate introductory…

DeKorver, Brittland K.; Towns, Marcy H. – Journal of Research in Science Teaching, 2016
Efforts to reform undergraduate chemistry laboratory coursework typically focus on the curricula of introductory-level courses, while upper-level courses are bypassed. This study used video-stimulated recall to interview 17 junior- and senior- level chemistry majors after they carried out an experiment as part of a laboratory course. It is assumed…
