For the past couple weeks, I’ve been immersed in deep, self-directed research to gain a full understanding of two topics: the DNA replication process and logical proofs. Because I missed classes in both of these subject areas during the time of their instruction, it was incumbent upon myself to rectify these gaps of knowledge. In the process however, my faith in the power of inquiry-based learning has been renewed.
According to Queens University, with inquiry-based learning, “students arrive at an understanding of concepts by themselves and the responsibility for learning rests with them.” Students take more responsibility for:
- Determining what they need to learn
- Identifying resources and how best to learn from them
- Using resources and reporting their learning
- Assessing their progress in learning
By missing classes and the direct instruction provided on these topics, it became necessary to conduct my own individual research to understand the concepts. While the process certainly isn’t easy, and could’ve functioned quicker with the appropriate facilitation, I do believe being forced to research the topic in greater depth has given me an improved understanding of the concepts. Here’s how it went down:
With DNA replication, my issue stemmed from an inability to understand the process via the textbook. I certainly appreciated the little colour pictures of meiosis and chromosomes, but there was just too many terms/steps and I didn’t see how they connected. Most of the static information I found on websites left me with the same problem, although those pages without pictures completely threw me off (there’s real value in visualization sometimes!).
The one source I ended up finding tremendously useful was the Khan Academy, a one-man repository for visual lectures on math and science topics. Fortunately for me, Khan had a couple great videos explaining DNA, the replication process, and the difference between chromatin, chromatid, and chromosome. His videos, coupled with the brief background I had established from my textbook and other research, allowed me to finally grasp the concept. Unfortunately, the midterm had far more questions on archaeologists than on biology!
For logical proofs, I haven’t quite reached my ‘aha’ moment. Without the class lectures, I’m undoubtedly at a loss. My textbook’s semantics make for a difficult read (it is written by philosophers!), and, as I’ve noted in a prior post, my TA for the class doesn’t provide much aid due to a lack of background in effective teaching. As a result, I turned to the internet to solve my problem – this time however, it hasn’t quite helped.
Logical proofs is one of those higher level, less common topics, which I think is at the core of my issue. Because it is such a specialized area, there’s a severe lack of information about it online. While I found a couple of great videos on YouTube made by teachers or profs for their courses (but shared for the world!), a lot of this information covered the foundations of sentential logic, rather than discussing how to actually solve proofs.
The one resource that has proven handy is a free online course from Carnegie Mellon. While the curriculum certainly isn’t parallel to my class, it has been a great resource. By structuring and teaching the content in a different way, it forced my brain to dig up what I had previously learnt and use it in unfamiliar methods, helping to review and solidify concepts.
In both scenarios, I had been provided with a brief, sometimes unintelligible background on a topic through my assigned textbooks. With these pieces of knowledge, I ventured out into the world wide web to discover how other people explained the topic. Some were helpful, many were not, but the process of researching, sifting through information, and collating the most useful tidbits ultimately helped develop a deeper understanding of the topics than I would have received via direct instruction. Certainly, I remember much more about DNA replication than almost anything else this entire semester.
Inquiry-based learning isn’t perfect by any means though. As I noted with logic, a lack of accessible information online has made the process much more difficult than with simple biology. In addition, researching can become overwhelming to those unaccustomed to the process of information gathering. The lack of control over what a student learns can also be an issue – i.e. I ended up focusing way too much on DNA replication than on learning what archaeologist discovered which fossil, although this can be solved with the proper direction and clear guidelines provided by a teacher. This final downside, a lack of scaffolding in my case, is the biggest concern with inquiry-based learning and, I believe, reveals exactly what teachers need to be to help their students engage deeply in research: education facilitators on the student’s side, helping and challenging them every step of the way, providing that essential human scaffolding as the student’s skills develop.
