Article Discussion
(1) As a reply to this post, give a title and URL of an article of interest. Make sure your article discusses the hypothesis being tested, the methods used to test the hypothesis done and the conclusion that was research.
Give a brief description to make this appealing to other students. Your description should include the hypothesis and conclusion but not the methods. Use your own words and avoid quoting here.
(2) Reply to at least one other poster to say why you thought the article was interesting. Then, by e-mail, send me a description of the methods used to determine the conclusion. Use your own words and avoid quoting.
Note: this site will be used for 3 different classes. You might be replying to someone from a different class. I teach BIOL 121 (intro biology for health science students) BIOL 127 (Cell Biology for transfer students) and BIOL 270 (Human Genetics)
(3) This is a game of sorts. The person who gets the most responses will be the “winner”.

Sequence Games 2019
In order to help students understand biological processes, I have developed several “sequence” games. In these games, students try to put several events in order. Several of them require little or no understanding of the particular process, the students are able to use logic to figure out the correct order.
Activity 1 Introduction to Meiosis
I give this activity before any discussion of meiosis. The students are able to understand basic concepts of meiosis without being told anything about how meiosis works.
In this activity cards representing different stages of meiosis (and the preceding interphase) are arranged in order. The original cell has an X chromosome (long) and and a Y chromosome (short) which makes it easier to determine what is happening at each stage.
Preparation. The game cards powerpoint has cards that can be printed out on card stock. Each group of 3-4 students should get one set and one set of instructions ( The Meiosis activity document below).
Prior to the exercise, I go over what happens to the X and Y chromosomes in mitosis using the same type of diagrams. This is shown below
Introduction to meiosis description
Activity 2 steps in Meiosis
This activity is an activity that has 2 purposes
(1) To help students integrate genetics and meiosis
(2) To help students understand the order and relationship between events in Meiosis
The activity is a game based loosely on Timeline a commercial game in which players attempt to put historical events in order.
In this game, students form teams of 2-3 players. The players start with 2 cards describing events of meiosis. The students must put these in the correct order. Once this students have attempted this, they check the first page of a key that tells then whether they are correct. If they are, they get a point. The team then goes to the next card and tries to order the event with respect to the first 2 cards. The students check the key as before. There are a total of 7 cards and the task becomes more difficult as there are more choices at each step.
Rules for The Basic Meiosis Game
Here is an electronic version of the game above
Activity 3 Steps in Respiration
Here is a game to help students understand respiration. Teams of students will get points for putting steps of respiration in the correct order.
The game includes a set of rules, game cards and a key
Insulin Signal Transduction
In this activity, students put steps in insulin signalling in order. The students can accomplish this with limited knowledge of this process. However, it helps to have been introduced to membrane transport and macromolecule biosynthesis. The activity will then reinforce what they know they know about these processes. For example, after completion of this activity students are asked about how conversion of glucose to glycogen affects the concentration gradient of glucose from the blood to the cell. This question and others are in the worksheet that is listed below.
The cards are here
There are 2 ways to play the game. The first is best used when students have had no exposure to the material, the second can be used as review.
In the first version, all of the cards are placed face up and the students put them in order. The letters in the front are ignored, but the back of the cards are marked with the letters to spell “Great Job” when the cards are put in the correct order. You can make this exercise a race in which the first team to get the cards in correct order wins.
The second game uses the same cards The rules and key are shown below
Rules for Insulin Signalling Game 2
The key should be printed out and each step should be a separate page. The whole key is then stapled together and the students turn one page at a time to check whether they have done the exercise correctly.
Discussions
I was asked to contribute to LCC’s new online teaching certification course by saying something about on-line discussions. I thought maybe the best way to do this would to be to have…an online discussion. While I have taught a couple of hybrid classes, last fall was the first time I have taught a class fully online. Thus, I am a novice at on-line classes in general, and discussions specifically. However, one online discussion went fairly well and I will give all of the credit to the source material which was written well and touched some nerves.
Here are the two source articles which center on two people dealing with different types of muscular dystrophy. One is a mother whose sons suffer from the condition and the other is a young woman who has a form of the disease that doctors have had trouble diagnosing.
THe DIY Scientist, the Olympian and the Mutated Gene
Below is a link to the discussion itself
It should be noted that while this discussion was required for the on-line class, my face to face class students could also participate for extra credit. Since I have separate sites for my online and FTF classes (Some people manage to combine these into one class, but I am way too disorganized to pull that off) one can not easily have this kind of discussion in D2l. However, the OpenLCC site is perfect for this (Thanks, Jim Luke!)
It should be noted that I had several purposes in mind when assigning this discussion
First, to give understanding of the ethical issues involving serious genetic conditions
Secondly, to understand what is meant by spontaneous mutations and why conditions like muscular dystrophy can arise without previous family history (Based on exam results, I need to discuss this a bit more thoroughly)
Thirdly, a more general question about one’s responsibility to understand what one is talking about and at the same time, how someone with little formal training can make important contributions by making the effort to learn.
Any comments on this or other advice to newbys on discussion forums is very welcome!
