Although kinetics forms a foundational part of the chemical curriculum, laboratory experiences with the subject are often limited and lack relevance to the actual practice of chemistry. Presented is an inquiry-based lab focused on Michaelis-Menten kinetics, implemented in an upper-level, university physical chemistry laboratory. Student learning…

Overall, the major chemical information retrieval products Reaxys and SciFinder have several similarities such as numbers of document records, numbers of characterized substances (counting the PubChem Compounds integrated in Reaxys), and, possibly, numbers of different chemical reactions. Reaxys has well over 100 times the number of experimental…

The Leidenfrost nanochemistry synthesis of gold colloids was introduced in this "Journal" as an advanced method to synthesize gold nanoparticles during an undergraduate nanochemistry research project. When trying to repeat these experiments in the laboratory, we experienced difficulties in the synthesis of the gold nanoparticles since…

Numerous previous studies have reported the difficulties associated with learning the Brønsted-Lowry acid-base model. The Brønsted-Lowry acid-base model requires complex systems thinking because it considers random interactions between reactant and product particles and effective particle collisions in forward and reverse reactions. The system…

Thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and computational chemistry are used in concert to evaluate the thermal decomposition of calcium acetate monohydrate, Ca(C[subscript 2]H[subscript 3]O[subscript 2])[subscript 2]·H[subscript 2]O, and to engage students in high-level thinking as they synthesize results…

This article presents an investigation into the environmental impacts of plastic waste and discusses the importance of cradle-to-cradle design thinking. An example lesson is provided that aims to focus students' attention on the influences of design decisions and conceptualizes design as an iterative process, whereas previous solutions may address…

Multiple chemistry education research studies at the secondary level have characterized students' difficulties regarding a conceptual understanding of the quantum model of the atom. This research explores undergraduate students' interpretations of multiple representations of the atom. Semistructured interviews were conducted with first-year…

When characterizing students' item-solving strategies, methods such as interviews and think-aloud protocols are often used. However, these measures provide limited information about sub-or preconscious signals and cognitive processes that also affect students' item-solving strategies and abilities. A growing number of researchers in chemical…

BYOL (Bring Your Own Lime), a novel laboratory experiment, is introduced in this paper. Students are encouraged to bring affordable household and grocery store chemicals into the classroom. The Bring Your Own Chemical (BYOC) concept demonstrates to students that food and household products are chemicals too. Citruses are often used to highlight…

A method for using electronic structure calculations to predict the standard molar enthalpy of combustion for hydrocarbons is presented. In this approach, simple geometry optimizations can be used to accurately compute the enthalpy of combustion within 3% of the experimental value using Hartree-Fock, MP2, or virtually any functional in density…

The purpose of this research was to understand the misconception level of 10th grade students in Yogyakarta province of Indonesia in understanding the concept of ionic and covalent bonds. The ionic and covalent bonds were chosen based on the need assessment on chemistry teachers. This study was included qualitative descriptive research which…

Gay-Lussac's law states that the pressure of an ideal gas is directly proportional to its absolute temperature if the volume is constant. Students observe this relationship by taking measurements on the pressure of gas in a flask or metal sphere at different temperatures and then extrapolate the data to estimate absolute zero. In our college…

Through problem solving especially in the chemistry courses, individuals are required to solve difference types of problems both in traditional and innovative ways, and to reveal different points of views. Both correct results and correct units are achieved through the conversion factors. The fact that the teacher candidates approach problem…

Many teachers do not notice, or do not understand, the chemistry going on in and around their homes and hence do not point it out to their students. Thus they miss out on an important motivating experience. This article gives a few random examples, most of them well within the understanding of students at key stages 3 and 4 (age 11-16). From…

This article argues that we need to make use of our everyday experiences when introducing concepts in chemistry that are often obscure. It uses reaction rates as an example and explores a common misconception related to the explanation of the effect of rising temperature on the rate of slow reactions.
