This work seeks to add to the growing body of chemistry education research that emphasizes the teaching and learning of advanced topics, focusing on students' understanding of enzyme kinetics. The data corpus relevant to this study involved 14 second-year undergraduate students enrolled in an introductory biochemistry course taught in a chemistry…

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…

Securing a first academic job in the United States as a young professional can be a very time consuming and stressful process. Candidates must carefully apply and then typically navigate off- and on-campus interviews. Although there is some literature dedicated to aiding in this process, some areas are not extensively discussed, such as contract…

Kinematic models are often very useful. The back and forth throw of a ball between two ice skaters may help us appreciate the meson exchange theory of Yukawa. If the skaters throw the balls at each other, they move backward, which is equivalent to a repulsive force between them. On the other hand, if they snatch the ball from each other, the…

The goal of this study was to assess students' level of conceptual understanding of chemical kinetics and equilibrium using topic-specific pedagogical content knowledge (TSPCK)-based instruction in chemistry grade 11 students. The research was a mixed approach that involved 159 grade 11 chemistry class students from Addis Ababa administrative…

In this paper we describe a simple alternative to the telephone book friction experiment, a classic demonstration where a small force (generated for example by the bending of the outer pages) is amplified by the large number of surfaces in contact, resulting in a huge maximum static friction force that has to be counterbalanced in order to…

Student-centered teaching has become increasingly common in higher education as researchers have demonstrated its efficacy in recent decades. Herein, we hope to establish an efficient problem-based learning (PBL) method, which can help upper-division students learn organic chemistry content by combining teaching materials, experimental literature,…

The law of conservation of momentum can be applied to a wide range of processes whether it is the collision of subatomic particles, rocket propulsion, or the recoil of a cannon. In this experiment two technologies, the Arduino microcontroller and a PASCO smart cart, are used to create a movable rubber band launcher. The Arduino microcontroller is…

A qualitative biomechanics (functional anatomy) course is a typical course in kinesiology curriculum. Most evidence suggests that biomechanics learning could be improved with the inclusion of laboratory experiences. However, implementing laboratories into biomechanics curriculum is difficult due to cost and time constraints. This study was…

This research aimed to measure the coefficient of restitution (COR) for tennis and golf balls using smartphone sensors. The ball and smartphone were attached at the ends of a long plastic strip: one end was a pivot with the attached smartphone and another end was for the attached ball. The ball on the plastic strip was swung to bounce the ball.…

Enzyme kinetics is an essential topic in undergraduate Biochemistry courses. A laboratory work that covers the principal basic concepts of enzyme kinetics in steady state is presented. The alkaline phosphatase catalyzed reaction of phenyl-phosphate hydrolysis was studied as a model. The laboratory experience was designed to reinforce the concepts…

Student understanding regarding topics in upper-division courses, such as biochemistry, is not well represented in the literature. Herein we describe a study that investigated students' reasoning about Michaelis-Menten enzyme kinetics and enzyme inhibition. Our qualitative study involved semistructured interviews with fourteen second-year students…

This study examined the effects of using the Feedback Loop Model (FLM) in Grade 12 Senior High School (SHS) Physics classes. Using a one-group pretest-posttest design, 58 students identified from a simple random sampling method were tested for their conceptual understanding and engagement with in kinematics. The results showed that students'…

This study reported the application of an interactive Open Education Resource, namely, an open virtual experiment simulator education tool (OVESET), in teaching the kinetics of atom transfer radical polymerization (ATRP) in a polymer science classroom. The OVESET ATRP kinetic simulator aims at improving students' inductive reasoning skills.…

Scientific literacy is an important skill for students' success, given the characteristics of today's society. However, not all students have a natural predisposition toward science, chemistry in particular. Considering the relevance of transdisciplinary learning, schools should foster the scientific abilities for which students may have less…
