A computational experiment investigating common organic chemistry mechanisms has been developed and implemented in a junior/senior-level physical chemistry laboratory course at two institutions. Students investigated various reactions that proceed via S[subscript N]1, S[subscript N]2, E1, and E2 mechanisms using hybrid Density Functional Theory…

This study aimed to determine the effect of a cooperative learning model (CLM) on preservice classroom teachers' attitudes towards science experiments. The sample consisted of 45 students in the department of primary education of the faculty of education of a public university in the 2017-2018 academic year. The sample was divided into two groups:…

The framework of ecosystem services (ES) and disservices (ED) has increasingly been used in various science, technology, engineering, and mathematics (STEM) disciplines, including soil science. The objectives of this study were to use ES/ED concepts to extend and test an existing lecture and laboratory exercise on soil organic carbon (SOC) in an…

In response to remote learning needs during the COVID-19 pandemic, introductory lecture and laboratory courses typically delivered fully in person were offered in a completely virtual format for the first time. Introductory laboratory courses are pivotal foundations for future discipline-specific learning and serve as prerequisites for a myriad of…

Clustered regularly interspaced short palindromic repeats (CRISPRs) represent a novel type of adaptive immune system found in eubacteria and archaebacteria. CRISPRs have recently generated a lot of attention due to their unique ability to catalog foreign nucleic acids, their ability to destroy foreign nucleic acids in a mechanism that shares some…

Laboratory courses are often designed using step-by-step protocols which encourage students to conduct experiments without thinking about what they are doing or why they are doing it. Such course design limits the growth of our students as scientists and can make it more difficult for a student to transition to the expectations of a research…

Here, we describe the implementation a hybrid general chemistry teaching laboratory curriculum that replaces a portion of a course's traditional "wet lab" experiences with online virtual lab modules. These modules intentionally utilize representations on all three levels of the chemistry triplet-macroscopic, submicroscopic, and symbolic.…

The purpose of this research is to determine the effects of different laboratory approaches on students' understanding of wave concepts. For this purpose, three experiments and experiment instructions have been designed for each of the three approaches (verification, hypothesis testing, and the 5E laboratory approach). Quantitative aspects of the…

The development of computer-based experiment set has become necessary in teaching physics in schools so that students can learn from their real experiences. The purpose of this study is to create and to develop the computer-based experiment set on simple harmonic motion of mass on springs for teaching and learning physics. The average period of…

Teaching blackbody radiation within the framework of astrophysics can motivate students to learn and obtain a more profound and qualitative understanding of the subject. In this paper we present a teaching module that intertwines teaching blackbody radiation via the continuous spectrum of hot objects, especially the stars. The module's approach…

Along with substantial consensus around the power of active learning, comes some lack of precision in what its essential ingredients are. New educational technologies offer vehicles for systematically exploring benefits of alternative techniques for supporting active learning. We introduce a new genre of Intelligent Science Station technology that…

Analytical method transfer (AMT) and dissolution testing are important topics required in industry that should be taught in analytical chemistry courses. Undergraduate students in senior level analytical chemistry laboratory courses at Kennesaw State University (KSU) and St. John Fisher College (SJFC) participated in development, validation, and…

The purpose of this study was to investigate the effectiveness of the experimental system design related to plasma state on the gifted students' understanding on the subject of the plasma state. To test the research hypothesis, one group pretest-posttest research model was carried out with 18 eighth-grade (4 girls and 14 boys) gifted students in…

We devised a half-day laboratory exercise for a group of 10th grade homeschooled students enrolled in an honors-level high school general chemistry course organized by a collective of homeschooling families associated with local Christian churches. Anecdotal evidence suggested that the students met the learning objectives of the exercise. The…

This paper discusses laboratory activities that can improve the meaningfulness of natural product chemistry course. These laboratory activities can be useful for students from many different disciplines including chemistry, pharmacy, and medicine. Students at the third-year undergraduate level of chemistry education undertake the project to…
