A number of useful and interesting exercises regarding nucleus and nuclear fission are performed to make these concepts more understandable to high school or even college students.

With improving technology and monitoring efforts, the availability of scientific data is rapidly expanding. The tools that scientists and engineers use to analyse data are changing in response. At the same time, science education standards have shifted to emphasize the importance of students making sense of data in science classrooms. However, it…

Science diagrams are an integral part of science because they are an important means of conveying and visualizing abstract science content. In recent years, researchers have demonstrated the educational benefits of encouraging students to draw their own conceptual diagrams, rather than focusing on interpreting diagrams given to them. To help…

Inquiry-based instruction has been promoted worldwide to achieve scientific literacy among citizens. This kind of reform-based instruction requires science teachers to have specialized knowledge called pedagogical content knowledge (PCK) for teaching science, which includes a set of knowledge and beliefs. Orientations to teaching science are…

This study shows how students can learn about green and sustainable chemistry by using the knowledge perspective of a local indigenous culture as a starting point. This learning approach encourages students to learn chemistry by connecting culture with learning about green chemistry. The cultural context selects the use of a phytochemical agent…

Trust in science is indispensable and very important for the development of global health, and can certainly be gained by developing the scientific literacy of the whole population. The article presents various definitions of scientific literacy and seeks its connections to science education. It further explores the progress in developing…

National and state science learning standards urge K-12 educators to offer authentic Science, Technology, Engineering, and Mathematics learning experiences. One way to fulfill this goal is to prepare preservice science teachers to integrate computer science skills, such as coding, into science education learning contexts that can benefit from it.…

With increased technology use in classrooms, teachers must design lessons that integrate technology use and stimulate cognitive processing. This dissertation explored science teachers' perceptions of integrating technology-based instruction on cognitive processing in secondary school science. It is vital to understand the neuroscience behind…

An introductory normal phase column chromatography experiment is described and evaluated for second year undergraduate chemistry laboratory class. The experiment involves a nucleophilic substitution yielding a crude mixture of reactant and one product, both of which are brightly colored and contrasting, creating a clearly visual separation when…

A flipped classroom describes a class where students complete readings and watch lectures outside of class, while in-class time is spent on activities to practice content learned. The implementation of a flipped classroom approach has been shown to increase student learning and student enjoyment of courses. This paper describes using the flipped…

Instrumentation plays a critical, ubiquitous role in modern chemistry. The undergraduate chemistry curriculum must therefore cultivate students' ability to investigate chemical phenomena via relevant instruments. The instructional laboratory serves as the primary context in which undergraduates learn about instrumentation, where use of instruments…

Catalysis and catalytic cycles are widely used in both research and industry. The addition of a catalysis experiment into the undergraduate laboratory curriculum is important and necessary training to expand student learning. Here, an experiment demonstrating iron-based tandem catalysis was developed and implemented in an organic chemistry course…

The two-semester General Chemistry laboratory sequence for nonchemistry majors at James Madison University has recently made the transition from expository, confirmation experiments to project-based (first semester) and research-based (second semester) curricula; this narrative will describe the development and current state of the Brewing Science…

This research developed learning activities for students to explore and connect the concepts of acid-base titration, equivalence points, pK[subscript a], and molar absorption coefficients. Polyphenolic compounds consisting of p-coumaric acid (CMA), caffeic acid (CFA), and 3,4,5-trihydroxycinnamic acid (3,4,5-THCA) were selected as study models.…

A straightforward procedure for the synthesis of (Ph[subscript 3]P)[subscript 3]CuCF[subscript 3], a robust, air-stable trifluoromethylating agent, is reported herein. This preparation can be completed in a single 3 h laboratory session and typically provides ample yields (~79--86%) and high purity (>90%). The target complex is characterized by…
