TEACHING IN MY OWN PERSPECTIVE
Personally, I believed that teaching is love in its purest form. Why is that so? It is simply because, teaching is the act of sharing the knowledge given by others to us with the hope that someday in some way at some particular point it will be again passed on to someone.
My passion in teaching started blooming since I was 19. I used to teach my close friends after classes during study group session but then these group of people keep expanding from time to time particularly, when exams were around the corner! Since I really enjoyed teaching, I then requested to help the school in handing some tutorial classes as well as lab session for the undergraduate while I did my Masters. No doubt, it was quite tiring as my schedule was usually packed. But I learned a lot particularly in doing multi-tasking, which require effective time management. Besides, I also learned to deliver formal teaching technique. The main challenge I faced at that time was to draw their attention in class because I was just as young as them. But at the end of the day, I managed to teach them with full of joy. What was the secret behind that? Simple. Be kind, understand the student needs, show some empathy, be approachable and have some fun while teaching! When I was in the UK doing my PhD at Keele University, I thought I would not have the opportunity to do any teaching there. But I was totally wrong. After about 7 months of my PhD, I was given a Masters student. Her name is Jessica Bratt. I was supposed to teach her to do all in vitro biological testing for the materials provided from a company, which I myself just learned for that 7 months (bear in mind, I was a Materials Engineering student who just started venturing in Biomedical Engineering field of study)! Big task! But alhamdulillah, on top of my super duper busy days in lab working on my own experiments, I managed to teach and guide her to finish the project successfully. Although we both had to work for long hours (18 hours/ day is considered normal), we still had so much fun working and learning together. To my surprise, at the end of her project, she then decided to continue her PhD at the same place in the same group as she got inspired by me! Fantastic! Jessica Amy Josephine Bratt, you are my first student (officially) and the best student I had so far. All the best fighting in your PhD battle! I am sure soon you will make me proud. Well, you are already making me proud by being a good teacher to your student. To my two amazing teachers in my PhD journey, Dr Ian Wimpenny and Dr Yvonne Reinwald, hope I had make you both proud by passing the knowledge that you gave me to the juniors and be a good teacher (hopefully) like both of you. Thank you for continuously guiding me from day 1 of my PhD till the day I became Dr Yanny and still supporting me even to this day.
THE JOY OF TEACHING
EBB 212 RAW MATERIALS & STRUCTURAL CERAMICS
Since August 2016, I had been teaching 3 core courses, 3 lab classes and advising 1 entrepreneurship course. EBB 212 used to be one of my favourite course in my undergraduate and now I myself is teaching it. Exciting. EBB 212 is a core course with three (3) unit credits for the second year Materials Engineering students. All Engineering Schools in Universiti Sains Malaysia (USM) practices Outcome Based Education (OBE) system. Therefore, all teaching materials and assessments including examination and coursework are prepared and vetted based on the Engineering Programme Accreditation Council (EAC) Manual 2017 by Board of Engineers Malaysia (BEM). Recently, Materials Engineering Programme at the School of Materials & Mineral Resources Engineering had successfully obtained a six (6) years accreditation (2018-2023) from BEM. Congratulations to my accreditation team! We did it!
EBB 212 RAW MATERIALS & STRUCTURAL CERAMICS
COURSE SYNOPSIS
This is the first course on ceramic engineering and deals with two basic components, viz. ceramic raw materials and conventional structural products.
Raw materials for all types of ceramics will be introduced. Ceramic raw materials will be classified as powders derived from natural resources and chemical synthesis powders. The most important raw materials from natural resources will be clays, such as kaolin, ball clays, fireclays, brick clays, etc. Topics include genesis of clays, geological formation and different uses of clays will be highlighted in relation to the physical, chemical and mineralogical characteristics. Also introduced are natural resources such as silica sand, limestone, feldspars, etc. The uses of these materials on their own or in combination in present day ceramic engineering products will be highlighted, such as whitewares, glass, cement, etc. The various chemical synthesis of ceramic powders will also be introduced, such as precipitation, sol-gel, hydrothermal, pyrolysis and vapor depositions methods. The effects of powder characteristics on the properties of final products will be discussed. Additives in synthesized ceramic powders such as binders will be included.
Structural ceramics include structural clay products such as clay pipes, roofing tiles, common and facing bricks, as well as cement and concrete. Agglomerates and aggregates. Types of cements and their composition will be covered inclusive of the wet and methods for producing Portland cement. Mineralogical phases in Portland cements and their effects on properties such as hardening, strength and sulphate resistance. Bogue calculation. Function of gypsum addition in Portland cement. Other types of cement such as high alumina cement, white cement, pozzolanic cement, etc. Concrete: components typical admixtures for engineering uses.
Powder preparation will be discussed. Preparation includes crushing, grinding and mixing. Mechanisms of grinding, types grinding mills and media. Filter press, Pug milling and spray drying. Effects of heat on ceramic products including drying and firing / sintering.
