Dictionary meaning of discipline: the practice of training people to obey rules or a code of behavior, using punishment to correct disobedience So discipline is all about rules and punishment for not obeying it. To go deeper into discipline we should question, What should be the rules? And what should be the punishment? Without defining the two, we can't really address discipline issue. Most of the time neither the rules are defined and made public. Neither the rules are practical enough to be followed. The first step should be to define the classroom rules, rules must be simple so that students remember the rule, as no one will remember complex rules: While I teach I have made 4 rules that work pretty well. 1) As I teach with discussion friendly, inquiry-based learning, I faced a big problem, where students always try to talk out of the context and irrelevant things. So I made a rule that for half an hour no one will talk or ask any irrelevant questions (not related to the topic)...

Growth of the bacteria refers to an increase in bacterial numbers When bacteria is grown in a liquid nutrient medium, the population is counted at many time intervals, and we get a bacterial growth curve that represents growth of cells over time. Why bacterial growth curve is so important? It gives the idea to learn about the impact of competition in the simplest way. It gives the answer what happens to a population when resources are limited. Bacterial growth best suits even to describe the human population. In science, there are 4 phases, but for simplistic understanding, without any scientific jargon it can be three stages: Thrive, Survive, and Deteriorate Image from wikipedia (A: Lag phase, B: Log phase, C: Stationary phase, D: Death phase) Stage 1: Thrive In this phase bacteria has sufficient resources, so bacteria flourish, prosper or grow vigorously. In science, it's the lag phase and log phase. In the lag phase, there is no cell division, but cells are not dormant, they und...

Jupyter notebook can be used to make your notes and solve exercises with programming without using pen and paper. In order to write notes, you can use markdown which is a very simple markup language and can be learned within 15mins to get started. You can use latex and Unicode characters to write equations and symbols. To learn latex you can use google, e.g. website https://en.wikibooks.org/wiki/LaTeX/Mathematics Jupyter notebook can be used in any subjects where the calculation is required, such as physics, mathematics, economics, even biology etc. No need to scratch your head, if you forgot the formula, or made mistakes in calculation when done with pen and paper. Learn by applying things that will be useful in real life situations Everyone should learn code, in early age just like other subjects. One computer to each child is required. https://github.com/amiyatulu/teaching_chemistry View: https://nbviewer.jupyter.org/github/amiyatulu/teaching_chemistry/blob/master/Integrated%20Rate...

If you are popular and have power, everything you do, share influences others. Anything you speak or write publicly, it's shared by thousands of people. So it's become very important to learn how to speak and write publicly.  You become the center of information, which gets transferred to everyone. Whatever you speak is most likely to be attacked because different people have different opinions, and some may have vested interest to attack. More controversial the topic is more attackers you will have. As a human we dislike attacks, so we start defending the attacks. Does responding to the attacks helps? In most of the time, it doesn't. You are only giving free airtime to them, knowing that you will respond, they will attack with a greater intensity. So what to do in such situation? If the critic is as popular as you, he/she can propagandize his opinion in a biased manner, even spreading rumors, non-factual, partial information that is logically correct to convince people tha...

Simplifying UTS Ticketing System which can be used in every station: We need two things: 1) OTP generator in Station (To track the location, no requirement of GPS) 2) A mobile app for payment and entering the OTP Railways job is to provide a unique account id and password to each customer after authenticating them. Use that unique account id and password to register on the app. You can add and change the mobile number. You can also change the password. When you go to the station, in the OTP generator, enter the unique account id, and get the OTP displayed on the OTP generator. OTP can also be sent to the mobile. OTP will work only for 15 mins etc. Enter the OTP on the registered mobile app, choose the route, pay and get ticket by SMS Payment can be done with using payment gateways or with balance kept on the account. You can add balance with payment gateways, may be with depositing money through railways or directly through gateways when you have no balance in your account. It solves m...

Mathematics needs a disruptive change, students who are not better problem solvers in all other fields are bad in it. UNDERSTANDING how the calculation works is the most important step to test and analyze a problem. A most common problem with students who are scared of mathematics is not understanding how fractions work. What will happen if you divide a decimal number between 0 and 1 with 1000 and 10,000 etc? What will happen if you multiply it with 1000 and 10,000 etc.? What is the meaning of 1/3 * 1/4? What is actually happening in it? How to divide a smaller number, for example, a decimal number between 0 and 1,  with a bigger number? What are you actually doing in this way, how will you explain it with the example, such as a cake or tiles? How to subtract a decimal number between 0 and 1 with a number greater than one? Fractions are everywhere, you will find not a single field in which you will not find its (mathematics) application, whether you do physics, chemistry, biology,...

Using just MCQs for entrance exams has many drawbacks. MCQs just test examiner way of thinking, not students, neither it tests originality of students. MCQs don't test what approach a student took to solve the problem, or why he/she was unable to solve it. Also, even if (s)he knows the strategy to solve the problem, many times (s)he can't reach the solution, because of mistakes in intermediate steps. The result is losing the marks. There are situations like unable to do the calculations, unable to recall the formula, even if he/she understand how the formula works. How many times you as a student feel frustrated for doing irrelevant silly mistakes and lose marks? I find many being frustrated for doing minor calculation errors, unable to recall even if they know it. Students are treated in a manner as if they are completely not allowed to make any mistakes. A question in chemistry about the rate of reaction does not test your logarithmic knowledge of mathematics. Even though it...

In a test, it's important to know the thinking process of a student, why a student is able to solve a problem and most importantly why he/she COULDN'T. If you understand why he/she couldn't do in details, you can address his/her problem and take corrective measure. TEST QUESTIONS (LEVEL 5) CLIMBING MOUNT FUJI Mount Fuji is a famous dormant volcano in Japan. QUESTION: The Gotemba walking trail up Mount Fuji is about 9 kilometres (km) long. Walkers need to return from the 18 km walk by 8 pm. Toshi estimates that he can walk up the mountain at 1.5 kilometres per hour on average, and down at twice that speed. These speeds take into account meal breaks and rest times. Using Toshi's estimated speeds, what is the latest time he can begin his walk so that he can return by 8 pm? The answer says 11 a.m., but the problem with me is understanding the question itself. I didn't know the meaning of trail, so I checked the dictionary,  which says a long line or series of marks that...
