I Do and I Understand

Curiosity is an inherent human nature. We want to learn about the world around us. And we have been doing so since the day we were born. When we are curious, we actively engage with the world around us and in that process learn about it. Unfortunately, our education system undermines this basic instinct of human beings. It treats students as passive learners or empty vessels. And the job of the instructors is to “fill students’ minds” with knowledge. Classrooms are treated as places to transfer information where the instructors act as the “sea of knowledge” who aim to transfer their knowledge to the students.

However, this system of knowledge transfer does not lead to students’ learning. Yes, the students do get some information in this process but they do not necessarily understand it. And they forget it after some time. Students are not empty vessels which can be filled with knowledge. They have a mind of their own. They think and construct knowledge out of what they hear, see and experience. And they learn in this process of knowledge construction.

If we want students to construct their own understanding, the only way to do that is to engage them in the process of learning instead of delivering content to them. And the way we can engage students in the learning process is by involving them in activities which lead to their learning. When students are engaged, they can learn the most difficult and intricate topics. This is because while they are engaged, they try to connect the new information to their long-term memory. This, in turn, leads to their understanding of the topic they are trying to learn. As the author James Paul Gee notes in his book What Video Games Have to Teach Us About Learning and Literacy, kids tend to learn even the most complicated of video games because they are deeply engaged in the process of learning it. There are multiple instructional strategies which can be used to involve students in the learning process. These include, but are not limited to, project-based learning, problem-based learning, case-based teaching, discovery learning, collaborative learning, co-operative learning and peer-teaching.

An old proverb suggests, “I hear and I forget. I see and I remember. I do and I understand.” If we want students to understand the content, we need to engage them in doing activities instead of making them hear lectures from the instructors.

Are Grades Credible?

Grades are used in the education system to assess the level to which students have achieved the learning objectives of a course or an assignment. Grades also act as feedback to students to indicate what they have learned and the deficiencies in their understating. While this system of giving feedback to students using grades has adverse impacts on students’ motivation and learning, I argue that grades do not necessarily say much about students’ learning and their ability to apply learning to real life problems. This is because the problems which students are required to solve on assignments or tests to obtain a grade are different from real life problems. This diminishes the credibility of grades to assess students’ learning.

Real life problem solving requires collaboration. I cannot think of any profession which does not require one to work with others. An engineering product is an outcome of the collaborative effort of all the people working on the product development team. A researcher is required to collaborate with other researchers to conduct their study. An airplane pilot needs to collaborate with other members of the flight crew and the ground staff to fly the plane. A surgeon needs to collaborate with other members of the medical team to perform a surgery. However, a majority of assignments which students submit for grade and almost all the tests which they take for grades are based on individual efforts. There is a possibility that a student works better when put in team as compared to when the same student is asked to do a task individually. Similarly, a student who does well on individual tests might not perform as well while working on a team. As a result, the grades which a student gets on individual work does not say much about their ability to apply their learning in the real world setting which is based on collaborative work.

Real life problems require the use of tools such as computing tools, drawing tools, design tools to solve problems. A lot of problems asked in the tests and assignments require students to do mental work. A good grade on a test may indicate proficiency with mental work but does not say much about whether one has learned the required skills to solve problems using tools in real life situations.

Real life problems are context-dependent. On the other hand, the questions which students are required to do for assignments are mostly abstract and devoid of context. For example, while writing an essay or an article, the writer needs to consider who the intended readers are, the kind of knowledge the readers will have about the topic and other such contextual details. However, such contextual details are usually missing when students write something for an assignment or a test. As a result, one cannot conclude whether the student has acquired the skills to write in a given context and for a given set of readers even if the student gets a perfect grade on an essay assignment.

There are a lot of skills required to solve real life problems. A lot of times, these skills are a part of course learning outcomes. However, all of these skills are difficult to measure. For example, it is difficult to measure students’ learning of teamwork and ethical issues in problem solving. As a result, the grade which a student gets in a course at the end of the term might not be based on the evaluation of all the skills which the students are required to learn from the course.


To answer the question I asked in the title of this blogpost, I would say that the grades which a student gets on a test or an assignment are not credible; and we need to stop valuing grades as much as we do and treating them as a measure of student’ learning.

A Better Teacher!

I had read somewhere that there are no difficult subjects, just bad teachers. For some reasons I believed in this and tried to see any student failure as the inability of the teacher or the system as a whole to transfer knowledge to the student. This was a year back and I had recently joined Virginia Tech as a graduate student and teaching assistant. The past one year in both the roles has taught me a lot about teaching and learning. And I hope working in both the roles during the next academic year will add to my learning.

Learning something is not like drinking a magic potion which a student can just gulp down the throat and be equipped with the desired knowledge.  It is like a bridge which can only be crossed with joint efforts of the teacher and the student. While a teacher has to understand the needs and attitude of the student and teach them accordingly, the later has to put an equal amount of effort in learning what is being taught. Even the smartest teacher cannot teach a student who is not willing to learn and even the smartest kid cannot learn from a teacher who is unable to understand the needs of the student and accordingly modify his/her style of imparting knowledge.

As a child I was told that learning is a difficult endeavor. Not that it is painful but it requires hard work and dedication. For some reasons I feel that is true. Working as a teaching assistant, I came across many students who would just be interested in getting the right answer instead of learning the subject. Needless to say they did not learn much from the class and during the time they spent with me. These are the kind of students who graduate from universities without much idea about what they learned in four years while they were attending college. I have heard my fellow teaching assistants complaining how students in their senior year at times are unaware of what they should know by the end of their senior year. On the other hand, there would be students who would try to understand the subject matter while trying to get their homework done. And the later were the ones who actually were able to appreciate the course material.

While I was in my undergrad, I had the same attitude towards education. I just wanted to score well in tests without trying to learn the course content. I managed to do fairly well when it came to getting a good GPA, but failed to learn what I should have during those days. On the contrary, in grad school, when I started putting serious efforts in learning, I feel that I am learning a lot. Not that the quality of teaching has drastically changed but it’s the step required to be taken by me which has lead to the difference. I had good teachers in my undergrad days and I have great teachers now, but the extra step taken by me has made me a better student.

While it is important to understand the role of student effort in learning, blaming just the kids for not putting in the required efforts can be overstretch. Students these days are forced to go on the traditional educational paths which can secure jobs for them while their interest lies somewhere else. For example, I know so many students who are studying engineering because it is a secure way of getting a job after graduating. Moreover, when the capability of a person is measured in terms of the degree he or she has or the grades obtained in tests, the quality of learning is bound to deteriorate. This system of education puts in little value in a child’s interest. If a potential musician is forced to become a doctor, he will surely end up becoming a bad one.

As Sir Ken Robinson says that the present education system was modeled to cater to the need of industrial revolution. We are now way past the industrial revolution time, and hence the system of imparting knowledge needs to change. And then we will have not only better teachers but also better students.

Goose Bumps!

What is knowledge? Who decides what knowledge is? How does the socio-cultural conditioning of the one who constructs it determine the nature of knowledge? I do not know the answers to these seemingly abstract questions, but I am sure I will know them someday. And very soon! However, what I know is that learning in any form makes me happy, be it technical, historical, social, information-based, or even understanding of knowledge as a concept.

But what has this to do with goose-bumps? Well the story which follows answers this question. Having a terrible day with respect to comprehending the lecture (Numerical Analysis & Software) today, I was looking for courses which I could pick up if I decide to drop the mathematics course (Gosh! I suck at mathematics!).  And then I decided to randomly browse the courses from each department till I stumbled upon the course “Constructivism and Knowledge”. I saw the course listed at 6:40 pm with one seat still left in the class. Interestingly the first lecture for the course was to start exactly 20 minutes later. I quickly decided that I was going to attend it: I looked for the location of the classroom and ran for the bus only to realize that I was late. The bus had already left, but luckily (for me), there was a road accident a few minutes back leading to a road block, which helped me catching the bus after a few minutes of running. As I got down from the bus, incessant rains welcomed me. I had to run again, this time to prevent myself from entering the classroom in rain-soaked cloths.

It is said that “what man proposes, God disposes.” But what I think is if man keeps on proposing, he entire cosmos conspires and forces God to accept the proposal. I reached the class on time, just on time. And this is when it began. Two hours of absolute fun, talking about knowledge, its nature and construction, and then how the learning about knowledge would be accessed by the professor. The class has people from six different nationalities, each having a different reason to take the course. It was fun to see how a skiing instructor who wanted to teach in high school was sitting with someone who just wanted to know something about constructivism and analyze it as a concept.

However, I have my concerns about taking the course. There are issues of getting a good grade in a non-technical course, taking a course which is completely out of sync with my major, pressure of making sure that my actions do not have any negative repercussions on my future and other such worries. But the joy which I got in a single class is incomparable. I wish each class had a similar feeling to it, a similar joy associated with it.


One thing I am extremely happy about is the fact that I broke the inhibition and went ahead to attend the class. To learn whatever I want to is the only reason that I wanted to go to grad school. To study and acquire knowledge without being constrained by factors like grades and funding gives me a joy unparalleled to anything else in the world. Not that I have become fully free from these entanglement (and I believe that one cannot ever be free from such restraining factors)but those few hours of boundary-less leaning made me suck the marrow out of life every moment. And hence the goose bumps!
