has been helping IIT Guwahati by delivering lectures and participating in a number of
important meetings. Department of Mechanical Engineering, very aptly, organized
this symposium in his honor. It was decided in the symposium to bring out a book
based on the papers presented and also collecting some other important papers on
the subject of pedagogy. This book is informative as well as simulative. Apart from
the topics on prevalent teaching methodologies, online teaching, and intellectual
property rights, it has several articles suggesting innovative pedagogical techniques.
This book will be very useful for budding faculty members of engineering.
There are a lot of challenges in educating the engineering students in this century.
Engineers have to be trained for becoming the leaders of change with emphasis on
sustainability. Compared to the last century, class sizes and variety of students have
increased tremendously. Hence, continuous upgradation in the teaching skills in the
need of the hour. National Education Policy 2020 of India also gives a lot of emphasis
to improving pedagogy. In fact, among Vedang (six auxiliary disciplines) of Ancient
India, Siksha, in modern terms pedagogy, is mentioned first. It is important that
leading academicians share their experience of best practices in education for the
overall improvement of teaching–learning process. This book is an attempt in that
direction.

Preface
Professor Amitabha Ghosh, former Director of the Indian Institute of Tech-
nology (IIT) Kharagpur (IITKGP) and former Professor and Head of Mechanical
Engineering at IIT Kanpur (IITK), is currently working as Honorary Scientist of
the Indian National Science Academy, New Delhi, and the National Academy of
Sciences, India, Prayagraj. He was born on December 3, 1941, in a remote village of
Birbhum district, West Bengal. As he completed the age of 80 on December 2, 2021,
he had served more than 56 years as Teacher. He is Highly Reputed, rather popular,
Faculty Member of IITK from 1971 to 2006, which includes his tenure as Director
of IITKKGP from April 1997 to April 2002. Professor Ghosh has trained several
students, both formally and informally, in the field of classical mechanics. Several
of his former students, admirers, and colleagues decided to organize a lecture series
and symposium on Engineering Pedagogy to commemorate the accomplishments of
Prof. Ghosh and to get benefitted from his teachings. Accordingly, 12 online lectures
were arranged on March 5, 6, 12, 13, and 19 in the year 2022. An online symposium
on Engineering Pedagogy was also arranged on March 20, 2022, with the august
presence of Prof. Ghosh. These online events were organized by the Department of
Mechanical Engineering at IIT Guwahati (IITG) under the patronage of Prof. T. G.
Sitharam, Director of IITG, and under the chairmanship of Prof. K. S. R. Krishna
Murthy, Head of Mechanical Engineering Department at IITG. It was decided to
publish selected high-quality papers presented in the symposium in the form of a
book. Later, the editors decided to invite a few more chapters from the experts and
bring out a nice collection of chapters on teaching pedagogy in the honor of Prof.
Ghosh, thus, this book.
Engineering Pedagogy has some distinct features, and it is very important for
the budding faculty members to learn from the experience of veteran engineering
faculty. Sixteen chapters contained in this collection are believed to be highly useful
for academicians and, especially, the young faculty members. Chapter 1 “Distin-
guishing Features of Engineering Pedagogy” highlights many important features
of engineering pedagogy. It also highlights the importance of toys in teaching–
learning process. Chapter 2 “Pedagogical Teaching—Teachers’ Beliefs, Capabili-
ties, and Examples” elaborates on certain points mentioned in Chap. 1. This chapter
vii
viii Preface
highlights four important aspects in Engineering Pedagogy in which “toys in loop”
is also an important aspect. The author has presented a number of practical exam-
ples of using demonstration toys in classroom teaching. Chapter 3 “Growth Mindset
in Engineering Pedagogy for Attitude Building with Metacognition of Engineering
Students” highlights the importance of growth mindset with metacognition in engi-
neering pedagogy. Chapter 4 “A Combination of Innovative Pedagogical Theories to
Enhance the Learning Output—A Case Study with Engineering Students” presents
an interesting case study of teaching Engineering Mechanics using innovative peda-
gogical methods. Pedagogical innovations are known to improve the performance
of the students. Chapter 5 “Effective Online Teaching and Evaluation Methods”
suggests some innovative methods of online teaching and evaluation. These methods
were tried and tested by the author. Chapter 6 “Internet-Based Learning and Teaching
of a Subject by Self-prepared Notebook” presents a case study of teaching a course
on solid mechanics with the help of Internet resources. Chapter 7 “Computational
Demonstration for Classroom Teaching of Classical Mechanics” presents an example
of teaching of a course on vibrations with the help of computational demonstration.
The entire procedure of writing code for a two degree of freedom problem has been
explained in detail.
Chapters 8 “Ethics in Publishing” and 9 “Innovation and Intellectual Property
Rights in Engineering Curriculum: A Pedagogy for Higher Educational Institutes”
highlight the importance of students’ awareness regarding intellectual property rights
(IPR). As publication and filing patents are the integral part of higher education,
engineering students should be made aware about it, so that inadvertently no IPR
infringement occurs by them. Chapter 10 “A Pedagogical Gadget for Teaching Heat
Transfer” discusses how a simple low-cost pedagogical gadget can be used for
conducting several experiments of heat transfer course. Chapter 11 “Uncertainty
Quantification—An Eternal Future of Engineering and Technology” argues intro-
ducing a course on uncertainty quantification because uncertainty is unavoidable
in engineering problems. Understanding uncertainty in quantifiable terms will be
helpful in mitigating its adverse effect. Chapter 12 “Introducing the Basic Quantities
of Mechanics” discusses how the concepts like kinetic energy and momentum can
be explained to students with the help of easy demonstrations.
Last four chapters are specialized chapters on engineering pedagogy. Chapter 13
“Practicing Hydraulic Autofrettage for Strengthening a Gun Barrel: Critical Issues
and Challenges” lucidly explains the concept of autofrettage. Autofrettage of a gun
barrel is an interesting example for explaining the concept of residual stresses in solid
mechanics. Jointly authored by persons from industry and academia, this chapter also
lists a number of practical aspects, which are normally not available in the textbooks.
Chapter 14 “Biointerface Phenomena in Biological Science and Bioengineering:
Importance of Engineering Courses” explains the concept of biointerface phenomena
and their inclusion in engineering curricula. Chapter 15 “Contact of a Cylindrical
Shell with a Flat Frictionless Rigid Substrate” is a topic of shell theory, which students
normally find difficult to understand. The authors of this chapter have explained
the numerical modeling of contact of cylindrical shell with a flat frictionless rigid
substrate in a simplified manner. Last chapter is about the evolution of machines and

mechanisms. The author discusses how mechanisms topic ought to be taught to the
current generation of students as modern topics creep into the curriculum.
We are grateful to all the authors for contributing their chapters. Besides the
authors, we also thank Dr. M. K. Sinha of NIT Hamirpur, Dr. B. N. Panda and
Prof. D. Chakraborty of IIT Guwahati, and Prof. S. Pandey, former Professor of IIT
Delhi for helping in reviewing of some chapters. Finally, we are grateful to Prof.
T. G. Sitharam, Director, IIT Guwahati, Prof. K. S. R. Krishnamurthy, Head of the
Department of Mechanical Engineering, IIT Guwahati, and Prof. S. Bandyopadhyay,
