Teaching and Learning Electrochemistry

Abstract

Numerous conceptual difficulties and misconceptions have been reported in the science and chemistry education literature about electrochemistry concepts such as electrolytes, redox equations, and about electrochemical (galvanic and electrolytic) cells. Other studies have considered teaching approaches aimed at improving learning and at overcoming misconceptions. This paper reviews these studies and considers strategies and approaches for the effective teaching of electrochemistry. Then, the review focuses on problem solving in equilibrium electrochemistry, especially problems involving the Nernst equation. The main findings of four studies with Greek university chemistry students, dealing with: (i) algorithmic problem-solving ability; (ii) practice on problem solving; (iii) the effect of the format of a problem; and (iv) the construction and evaluation of a website devoted to electrochemistry problem solving, are reported.

Improving education in electrochemistry via a modeling approach and focusing on green chemistry applications

“…3 The team thereby suggested avenues to reinvigorate electrochemistry education based on today's inexpensive electronics and open-source software providing new tools for teaching electrochemistry interdisciplinary concepts. 3 Similar findings were reported in 2019 by Tsaparlis in Greece noting that electrochemistry was a "hard subject for students" 4 due to complexity and plurality of its concepts. 4 Tsaparlis' study opens with a quotation of Japan's electrochemistry scholar Akiro Yoshino (awarded the Nobel Prize in chemistry in the same year for the development of lithium-ion batteries): 6 "battery technologies are electrochemistry, a complex and difficult interdisciplinary field".…”

“…Suddenly, recognizing the poor state of electrochemistry education in many countries, electrochemistry and chemistry education scholars started to publish a number of intervention studies on electrochemistry education. 3,4,9,10,12,12,13 In brief, evidence from numerous countries suggests that novel and better approaches to teaching and learning electrochemistry are required.…”

Pengembangan Aplikasi E-Book Elektrokimia Berbasis Android Untuk Menumbuhkan Self-Directed Learning Mahasiswa

“…Pada konsep sel elektrolisis, mahasiswa dapat menjelaskan bahwa terjadi pergerakan ion menuju elektroda yang sesuai tetapi gagal menjelaskan reaksi redok yang terjadi di elektroda tersebut (Kong, 2016). Lemahnya kemampuan memahami konten elektrokimia dapat disebabkan karena gaya belajar mereka yang masih berpusat pada pembelajaran yang dilakukan di kelas, tidak mencari alternative atau pemahaman sendiri di luar kelas dan tidak membiasakan mengevaluasi kesulitan-kesulitan belajar yang mereka alami (Tsaparlis, 2019).…”

South African twelfth grade students’ conceptions regarding Electrochemistry

“…Numerous conceptual difficulties and misconceptions regarding electrochemistry concepts such as electrode potential and galvanic and electrolytic cells have been reported in the science and chemistry education literature [2][3][4][5]. Similarly, despite the wide application of electrochemistry in industry and other fields, science ISSN: 2089-9823  South African twelfth grade students' conceptions regarding Electrochemistry (Kwaku Darko Amponsah) 363 teachers [6][7] and students alike [8][9][10][11][12][13] have difficulties with electrochemistry concepts. Correspondingly, alternative conceptions about electrochemistry have also been stated by several studies [14][15][16] which have indicated that electrochemistry can be described as one of the most challenging, problematic as well as demanding sub-disciplines of chemistry [17] since it has so many ambiguous and abstract terms with stated discrepancies and unreasonable representation [14,15,18].…”
