Redox reaction is an important concept in chemistry, and a well-organized knowledge structure of redox reaction is beneficial for concept learning. This study investigated the knowledge structure regarding redox reaction from 459 Grade 10 students. The pool of 15 redox reaction concepts was developed by content analysis, questionnaire survey, and…

Redox reaction is a core concept in teaching and learning chemistry. This article explores a new method for balancing organic redox reactions that requires the balancing of both atoms and charges. The H+, O, H[subscript 2]O, and e- are used as balanced vehicles in two half reactions. A non-oxidation number approach can be applied to both molecular…

Specific to the topic of oxidation-reduction (redox), teachers are obligated by the discipline to prioritise symbolic traditions such as writing equations, documenting oxidation states, and describing changes (e.g., what undergoes oxidation/reduction). Although the chemistry education research community endorses connecting the vertices of…

For the present lab demonstration, we have developed fluorescent indicators to detect the end point in microscale redox titration of ferrous ions in permanganometry, cerimetry, and dichrometry. Microscale redox titrations were carried out effectively in micromolar(µM) concentrations and semi-microvolumes of the analytes. At the end point,…

Redox reactions are considered one of the most difficult chemistry subjects to teach and learn. However, this is an important content that permeates several topics and includes many everyday life-related phenomena. To understand the teaching and learning difficulties of the 'redox reactions' topic, a systematic literature review was conducted.…

The schoolyard as a setting for teaching and learning is rarely the focus of chemistry education. Therefore, a chemistry unit combining activities in the classroom and the schoolyard was designed to support pre-service teachers'(PSTs) learning of redox chemistry. This study was conducted to investigate the PSTs' talk about redox chemistry as they…

This study aimed at designing a framework to help students develop a conceptual understanding of redox reactions, which draws on constructivist learning theory. This framework was in the form of participatory teaching and learning approach comprising Insight, Interaction, Task, and Forum. The framework was designed and developed based on the…

The mercury beating heart is a dramatic demonstration of redox chemistry that allows for the direct conversion of chemical energy to mechanical energy without involving a machine to accomplish the transfer. Unfortunately, instructors often avoid this demonstration due to difficulties initiating the oscillating redox reaction that drives the…

This article describes a study of 149 preservice chemistry teachers' misconceptions of concepts related to a reduction-oxidation reaction. A mixed-method approach was used to obtain data through the ROXCI (Redox Concept Inventory) instrument and interviews. Result indicated that the highest misconceptions were for item number 10 (4.03% or only 6…

As simple and ubiquitous redox-active organic molecules, quinones participate in diverse electron transfer processes in chemistry and biological systems for energy transformation and signal transduction. We introduce here a practical exercise to study the redox potentials of benzoquinone and its two derivatives by combining the electrochemistry…

Redox titration problems are considered difficult for students to learn due to their abstract nature, the myriad amount of representations, and the mathematical competency required to learn and solve. The goal of this research project is to examine challenges students face in learning about redox titration-related problems, approaches they use in…

This study investigated the use of collaborative instructional approaches on form two science students' performance in redox reactions. The sample for this study consisted of 106 science students from Winneba Senior High School in Ghana. The sample was selected from two intact classes in the school. After a pre-test organized for both classes, the…

The redox reaction between dioxovanadium(V) and oxalate is proposed as a suitable system to analyze the kinetics of a twostep reaction mechanism using UV-vis spectroscopy. First, the spectra of dioxovanadium(V) and its reduced counterpart oxovanadium(IV) are compared and explained using the crystal field theory. The change in absorbance can be…

Describes the exploratory assessment of strategy for learning redox reactions in High School, which seeks to prevent students from developing memoristic and mechanical skills, in addition to emphasize the experiences of daily life that go unnoticed or unexplained to the student in the classroom and at the same time are able to incorporate the key…

Understanding redox reactions in biochemistry requires a clear grasp of three definitions: electron exchange, oxidation number, and oxygen atom insertion. Here, the electrochemical cell is explained for redox-active ions, introducing a new comparison between the measurement of midpoint potential and the measurement of initial velocity for enzymes.…
