Linking Questions: History and Ways of Knowing


Boats
In this post I’d like to present a list of questions linking History with the different Ways of Knowing for classroom discussion.

Linking the different Areas of Knowledge (AOK) with different Ways of Knowing (WOK) can be quite challenging at times. I now attempted to link History with Language, Logics, Emotion and Sense Perception.

History and Language:

  • Does the way (the language) that certain historical events are presented in history books influence the way that the reader understands these events?
  • What role does loaded language play when talking about historical events?
  • What role do connotation and denotation play when talking about historical events?
  • How can language introduce bias into historical accounts?
  • How does language help or hinder the interpretation of historical facts?

What are the four Ways of Knowing (WOKs)?


old arches
In this post, a quick introduction into the four Ways of Knowing (WOK)!

So, you are now sitting in front of your computer reading this very post about the Ways of Knowing. How do you know that? Honestly! How do you know that you are reading this text right now? Is it because someone told you? Of course not. You know it because your senses tell you so. You can read the text with your eyes (vision), you hear the sound of the computer fan humming (hearing), and you feel that you are sitting on a chair (touch).

Philosophers have identified these four ways of knowing: Sense Perception, Language, Emotion/intuition and Logics/Reason. Pick one fact that you know and ask yourself what the sources of this piece of knowledge are. From where do you know it? You will soon discover that it is possible to trace you knowledge back to one of these four Ways of Knowing. Let’s start with a little example: “I know that atoms exist”. How do you know it? Have you ever seen, heard or felt atoms before? I can hardly imagine. Sense perception is therefore an unlikely source. Do you intuitively and emotionally feel their existence? Hopefully not! The most likely source of this knowledge is that someone told, most probably a teacher, you or that you read about them. The source of this knowledge is therefore language. Continue reading »




What is Logical Positivism?


Office Windows
Logical Positivism was one of the most important schools of philosophy of science in the beginning 20th century. The “Vienna Circle”, a group of scientists, mathematicians and philosophers, contributed greatly in promoting this philosophical view.

When I was younger, in my teens, I started to discover my love for the sciences. I was fascinated by Biology and Physics and I think I must have driven my teachers crazy with my constant request for “proofs” and evidence. I liked science so much that I even included chemical formulas in my literature essays. Instead of saying “The water waves are gently moving in the sunset.” I’d write “Waves made of H2O are gently moving in the solar spectrum.” My English teacher then responded, “Don’t forget about the H2SO4 (sulfuric acid) which is dissolved as well!”. An then I didn’t feel as bad about the bad mark on the test anymore… Now I am teacher myself and occasionally I meet some students who remind me very much of myself. They are constantly confronting me with the words “How do you know that?” – always eager for empirical, scientific evidence. They want to see things before they believe it. They want formulas. They want cause and effect relationships. Without having been aware of it, I myself as well as my students, were followers of a certain philosophical school. We were “Positivists”.

Newspaper Articles – Does Size Matter?


 

Metal door and key hole
How does the optical appearance of a newspaper article, the size of the headlines, the size of the pictures, influence its perception of its content by the readers? How does the context in which a newspaper article appears influence its perception by the readers?

I like to keep myself informed and I therefore like to read newspapers. Now with the internet being so widespread, I do not buy newspapers anymore, but rather visit my favorite newspapers online. Usually I start out with the computer news to keep myself updated on new products and developments, followed by science (deep in my heart I am a scientist, after all!) and politics and economics. The sports section I usually skip, I have to admit to you that I am not very competent in this particular area of knowledge. But I do read the sports section during the Olympics.

What is the “4-Ears Model” of Communication?

According to Psychologist Friedmann Schulz von Thun, when a person talks to another person he/she is passing on four different messages. This communication model is called the “4 Ears Model” and is useful in understanding why people misunderstand each other.

Alice and Bob are both sitting in the car, Alice is driving. They are waiting at an intersection, the traffic light is red and then changes to green.

Bob: The traffic light is green.

Alice: Don’t be so impatient!

… and they start arguing. What went wrong? According to the psychologist Friedemann Schulz von Thun, a message that is passed from one person to another person carries four pieces of information: Continue reading »




What are Formal Systems?

Introduced here: the MIU puzzle as an example of a formal system. A formal system is composed of axioms, to which rules of inference are applied to produce theorems to which the rules can be applied again. Confused? Try to MIU puzzle yourself – it’s fun!

The MU Puzzle is an example of a formal system. The objective of the MU Puzzle is to try to reach the string MU starting from MI, using only these four rules:

  • Rule 1: xI ? xIU. If there is an I at the end of the string of letters, then you can add a U. For example if your string is MI then you can change it into MIU. You can only add a U if the last letter is an I.
  • Rule 2: Mx ? Mxx. You can double any string that follows the M. So if your string is MIU then you can double the IU after the M. You will then get MIUIU. We have doubled the IU.

What are the differences between Facts, Theories and Opinions?

The terms facts, theories and opinions are often confused. The objective of this edition is to clarify these terms. Facts are observations or measurements from an experiment, theories are the explanation of these facts, while opinions are assessments or evaluations.

The terms facts, theories and opinions are often confused. The objective of this edition is to clarify these terms. Facts are observations or measurements from an experiment, theories are the explanation of these facts, while opinions are assessments or evaluations. Opinions are often not scientifically verifiable or falsifyable.




What are Thought Experiments?

It is not always necessary to conduct real-life experiments to reach a valid scientific conclusion. Thought experiments may in some cases also suffice. In this edition I will illustrate you a thought experiment from physics: In a vacuum, all objects accelerate the same way and they both have the same velocity. Heavy objects will not fall faster. But how can we test this? We do not have a large vacuum chamber to test this. A thought experiment can be useful in this case.

In this edition of TOK-Talk I will explain you what a thought experiment is. Is it always necessary to conduct real-life experimets to reach a valid scientific conclusion? Listen to find out!

Why are Simpler Explanations Usually Better?


 

Old door and hinge
The purpose of science is to make things simpler and not more complicated. Scientists strive to discover theories and explanations that simplify the view of our world and not complicate them. According to Wiliam of Ockham (c. 1288 – c. 1347), if there are competing explanations for a phenomenon, the simpler explanation is to be preferred. The simpler explanation is often the correct one. It can be summarized as “With all other things being equal the simpler solution is the better one.” Simpler explanations rely on fewer assumptions which can not be proven or disproven.

In this edition of TOK-Talk I would like to explore the difference between a good and a bad explanation. Why are simpler explanations usually the better ones? Listen to find out! Continue reading »




What is the Observer Effect?


 

Lonely tree
Every measurement changes the object that we want to measure. This is called the Observer Effect. When we stick a thermometer into a glass of water to measure its temperature, then the thermometer will change the temperature of the water as well. Similar effects can be observed when measuring voltage or current in electrical circuits. Also in the social sciences we have a similar problem: people will not behave naturally when they feel that they are observed.

In this edition of TOK-TALK we will explore if it is in principle possible to measure anything accurately. How does a measurement change the value of that what you want to measure? Listen to find out!

Here in front of me, I have a cup of hot water, and over here we have a thermometer. Let’s put the thermometer into the glass, we have to wait a bit for the temperature reading to adjust. For our listeners, it’s a digital thermometer with a metallic probe. You use similar thermometers to measure the inside temperature of a cake to check if it is finished baking. Continue reading »

Education is a private matter between the person and the world of knowledge and experience, and has little to do with school or college.
