Abstract

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. Initially, 318 articles were mapped, between the years 2000 to 2019, related to the teaching of redox reactions. The inventoried articles were analyzed to identify, in their results, the aforementioned difficulties. Only 54 presented difficulties related to teaching and learning redox reactions. To analyze these articles, the year of publication, the conceptual/procedural difficulties resulting from the study, the researched participants, and the strategies used throughout the data collection were adopted as categories. As a result, the main participants of the investigations were students. It was observed that the research studies favored bac...

A green chemistry teaching material: Its validity, practicality, and effectiveness on redox reaction topics
Ida Bagus Nyoman Sudria

2021

Currently, the chemistry practicums that are carried out in high schools still use hazardous chemicals. The use of these materials can make teachers and students less comfortable in carrying out practicums. This affects students’ interest and motivation in learning chemistry which in turn also affects students’ learning outcomes. This study aimed to develop a green chemistry teaching material on the topic of redox reactions in improving students’ learning outcomes. The development of this teaching material used a research and development method of the ADDIE model, including analysis, design, development, implementation, and evaluation phases. The analysis phase resulted in the approval of chemistry teachers to develop green chemistry teaching materials. The design phase produced the design of the teaching material with characteristics including the green chemistry principles, information about the dangers of chemicals used in the redox reaction practicum and countermeasures, replace...

Participatory Teaching and Learning Approach: A Framework for Teaching Redox Reactions at High School Level
Kenneth Adu-Gyamfi (PhD)

International Journal of Education and Practice

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 literature and used in a teaching trial. At the prototype phase of the design-based approach, a mixed methods design was employed in data collection. Fifteen students from a second-year senior high school class responded to the achievement test and interacted with the researchers. A stratified sampling procedure was used to select the students. In lessons on redox reactions, the framework helped the teacher to identify students" alternative conceptions and confronted them through cognitive engagements leading to conceptual understanding in redox reactions. Percentages, related samples t-test, and themes were used to analyse data. The results showed that there was an improvement in students" conceptual understanding of redox reactions. It is, therefore, recommended that chemistry educators and researchers should use the framework in large scale research to assure the scientific community the efficacy of it in developing conceptual change in students. Contribution/Originality: The study contributes to the existing literature by the design and development of an alternative framework for participatory instruction, which is all encompassing in approach. Unlike other instructions, the framework; Insight, Interaction, Task, and Forum, takes advantage of alternative conceptions and ends with students" ability to evaluate colleague"s presentations. 1. INTRODUCTION Concepts in electrochemistry (such as oxidation-reduction reactions) are considered to be challenging to high school students with associate alternative conceptions (Osterlund and Ekborg, 2009; Adu-Gyamfi et al., 2015; Bong and Lee, 2016; Adu-Gyamfi and Ampiah, 2019a;2019b). Students labelled the cathode of an electrolytic cell as the positive terminal and the anode, as the negative terminal, which is considered as an alternative conception. This was an alternative conception because students have explained oxidation occurs at the anode and the reduction, at the cathode, something they picked from text books with no conceptual understanding (Bong and Lee, 2016). Regarding balancing redox reactions, students" alternative conceptions are associated with the introduction of H2O, OH-, and H +. For instance, students have explained balancing of redox reactions in acidic medium as H + ions being introduced just because the reaction occurs in the acidic medium (Adu-Gyamfi et al., 2015). Students have

Students' Alternative Conceptions Associated With Application of Redox Reactions in Everyday Life
Kenneth Adu-Gyamfi (Ph.D)

Asian Education Studies, 2019

The study explored chemistry students' alternative conceptions associated with application of the processes of oxidation and reduction in real life context. As part of a design-based research approach, a case-study design was followed. Purposive and convenient sampling procedures were employed to select 213 senior high school students to respond to a diagnostic test. Data obtained were analysed using item difficult index, percentages, and themes. The results showed that alternative conceptions existed as preconceived notions, conceptual misunderstanding, and factual misconceptions. It is recommended that chemistry educators should select most appropriate instructional strategies to unearth and address alternative conceptions students may bring to the classroom.

Survey of High School Students’ Understanding of Oxidation-Reduction Reaction
Mei-Hung Chiu

Journal of Baltic Science Education, 2014

This study investigated the conceptions of 340 Taiwanese high school students (grades 10 to 12) regarding oxidation–reduction reactions. The diagnostic tool used was a two-tier test based on a concept map of redox reactions as presented in high school curriculums. The reliability of the two-tier test items was 0.82. The results show that most 11th graders performed equally well in questions related to the concept of the gain and loss of electrons during oxidation–reduction. In terms of working with oxidation numbers, scores increased with grade level. The results of this study provide valuable reference for curriculum designers and science instructors. Key words: concept map, oxidation–reduction, redox, two-tier.

Problems in Teaching the Topic of Redox Reactions: Actions and Conceptions of Chemistry Teachers
Adry junior

Journal of Research in Science Teaching, 1995

Although there is growing interest in studies of teachers' actions and conceptions, little is known about content-related teaching problems arising in science classrooms. This article presents a case study of problems which can occur when teaching the topic of redox reactions to Grade 11 students. Two chemistry teachers, a senior and a junior teacher, were involved in the study. Their reflective comments on the teaching problems were also investigated. Research data were obtained from classroom observations and audiotaped recordings of classroom practice. After the lessons, we conducted semistructured interviews with the teachers. The teaching problems are reported in terms of teaching activities causing difficulties for students in considering new conceptions to be necessary, intelligible, plausible, or fruitful. Analyses of the teachers' comments on these teaching activities clarifies a number of reasons why they acted as they did. It can be concluded that teachers' scientific expertise is an important source of difficulties when teaching redox reactions. Implications for an improvement of current chemistry classroom practice and content-related teacher training are offered.Received: 11 April 1994; Revised: 5 June 1995;

Exploratory Assessment of Strategy for Learning Redox Reactions in High School
Angelita Morales

International Journal of Education (IJE)

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 elements for understanding the terminology used in the language of Chemistry, all through proposal for a strategy. The sample consisted of sophomores from CBT High School No. 2 Bicentennial Huehuetoca in Mexico. The students are in the subject of Chemistry I.The didactic sequence was appropriate, for the learning of redox reactions, since it managed to increase by 41.9% the conceptual gain in the students.

Students’ Understanding of Redox Reactions in Three Situations
Margareta Ekborg

Nordic Studies in Science Education

Redox models that explain electrochemical issues have been found to be difficult to teach and to learn. The aim of this study was to investigate students’ reasoning about redox reactions in three situations, how they used the activity series of metals and if they transferred knowledge between domains. Semi-structured interviews were carried out with ten students on two different occasions and dealt with three situations 1) a laboratory practical on corrosion; 2) a demonstration of zinc and copper sulphate solution; and 3) a corroded sculpture. The results indicated that the electron model was fundamental and reinforced. The identification of the reducing agent in the situations was unproblematic. The students’ conceptions regarding the oxidizing agent varied and diverged from the scientific model in some situations. Depending on the situation, the activity series of metal became a tool as well as an obstacle. Some transfer of knowledge between the classroom and the outdoor situation...

Two Ideas of Redox Reaction : Misconceptions and Their Challeges in Chemistry Education
Garba Shehu

2015

In interpretations of chemical phenomena students particularly of Secondary School level like to mix substances from the macroscopic level, that is substances that can be seen, touched and smell with particles from the sub-micro level; atoms, ions, molecules etc. “hydrochloric acid is giving one proton” (instead of “One H3O (aq) gives one proton”). For redox reactions students are doing this too: “one Copper two ions takes two electrons and is reduced to Copper”: (instead of “to one Copper atom”). That is Cu2 + ion + 2e – Cu atom. Another difficulty seems to be the historical redox definition with the “Oxygen transfer”, this idea is so attractive that students argue most with Oxygen participation instead of the transfer of electrons. On the one hand the students do not see any connection between both levels; on the other hand it is left up to them to figure out which mental model they may choose concerning the sub-microscopic level. They are building up ideas on their own, mostly wr...

TEACHERS' PROBLEMS OF TEACHING OF OXIDATION-REDUCTION REACTIONS IN HIGH SCHOOLS
Kenneth Adu-Gyamfi (Ph.D)

European Journal of Education Studies, 2018

The study explored how teachers taught redox reactions to senior high school students. Within a case-study research design, six chemistry teachers with a minimum of 7 and a maximum of 12 years teaching experiences from three schools were interviewed. The results revealed four themes; inhibition of instruction, weak instructional strategy, inability to teach concepts, and teachers' professional development. It was found that teachers employed weak instructional strategies such as expository and out of class group assignments in teaching redox reactions. The study recommends that chemistry educators and researchers should design and develop subject-specific pedagogical content knowledge for teaching redox reactions.

    Evidence of the Development of Pedagogical Content Knowledge of Chemistry Teachers about Redox Reactions in the Context of a Professional Development Program
    Luciane Goes

    Education Sciences

    In this study, we investigated the impact of a continuing professional development program (CPD) on the development of pedagogical content knowledge (PCK) of chemistry teachers regarding the topic of redox reactions. For this purpose, a CPD program designed to develop teachers’ PCK on redox reactions was examined. During the course, teachers were observed and their activities were analyzed. The data collected were based on responses to the CoRe instrument, lesson plans, vignettes, and audiovisual records of the CPD program. Qualitative thematic analysis was employed to analyze the data, focusing on the five components of PCK proposed by Park and Oliver. The results demonstrate that teachers, after participating in the continuing education program, were able to independently develop the components of PCK at different levels, with the knowledge of instructional strategies showing the most prominent improvement. Additionally, it was observed that the components could potentially be int...
