This is how every professor, instructor, or teacher should be talking and lecturing. She talks clearly, precisely, slowly, and phase between each sentence or idea so that listeners and watchers can clearly understand. She wants to make the audience learn and comprehend not herself.

This was exactly what I needed to understand causal loop diagrams, you made it so clear and understandable. Thank you!!!

My 2 hour lecture condensed in a 16 minute KZread clip. Thank you so much!!!

Thanks a lot, Donna. You must be a wonderful professor. I love the way you deliver your lecture; it's super clear and extremely easy to understand.

Thanks a lot, Dr. Donna, you explain the concept so well in a simple way. Looking forward to more lectures from you.

Thanks a lot for explaining system dynamics in such a simple manner. This helped me a lot. Keep going.

This was a lovely, crystal clear lesson. Thank you.

Thanks alot Dr Donna, this is very helpful, you are so calm and clear, looking forward to more of your lectures.

Thank you Dr. Donna Gurule, this video has help me to better understand causal loop diagrams

Hey Dr. Donna! You are my hero, thanks a lot :)

Thank you Dr. Donna for the beautiful explanation

Modeling is the art of Simplification- the professor has well demonstrated!

Thankyou this really helped me understand causal loops much better!

Great description of causal loop diagrams!

Thank you Dr. Donna

Nice video Donna!, this was a great help!

Thank you for this video it helped me get a great grade for an assignment on causal loops

This video simplified everything for me, it's really helpful. Thank you

Thank you so much. You explained the concepts very well.

thank you do much donna, this helped me so much

Thanks. This is helpful to understand the concept in a simple way

Makes perfect sense!

Good video, also, very relaxing

it`s really help me out. Thank You !

crystal clear, thank you

Great lecture and very easy to understand. We will benefit even more with practical exercise in Vensim .

Well explained lecture. Thank you! 🙂

Very useful, thank you very much.

Thank You for the Explanation. Things are clearer now, but I need to practice.

I could not follow the logic between resource constraints and life expectancy but has been explained in comment below. It’s an amazing presentation overall.

Thank you Donna

CLDS protocols are that there is always increase at the tail then see the effect on head either positive or negative.

thanks a lot!

Thank you very much for your efforts

It is helpful....from Bangladesh.

Very effective video Dr. Gurule. I learned and enjoyed the pop quiz. Just a quick question - are causal loop diagrams and stock and flow diagrams the same? If not, Can you explain the different nuances between the two? THANK YOU :)

thanks it helps a lot.

Thanks I get it & short useful explaining keep going

Is it me that I'm not understanding correct or the first loop diagram at time 0:49 has the the arrows on both bottom loops are wrong going the wrong direction? The left top loop is going counterclockwise, right? So, the R arrow is also traveling counterclockwise. The lower left arrows are traveling clockwise, but notice the arrow around the R. The arrow is traveling counterclockwise. The same problem exists with the lower right side. Am I wrong or you all have a typo? Let me know, please.We are learning systems thinking in grad school.

In loop six, why is it not a + sign in front of herd size?

thanks DONNA

Thanks for the loop diagram information. Just one observation. I doubt you can bring data pointing to inequality driving conflicts of vice versa. Not even simple to build as conflicts might have many variables of influence. Keeping political views away helps on driving personal thoughts and so, diversity of thinking... in this case accepting my view that this doesn't work (based on reality by the way). That aside, thanks for the technical info, very useful!

good explanation

If life expectancy decreases then why it is indicated with positive sign, it should be negative

great video,.. but I would like to know the bank where I get interest for my money :)

Watching now

informative

Thanks for the interesting video! At 9:20, as there are fewer resources per person, shouldn't there be a minus in life expectancy and therefore also a plus in deaths?

Hi Alexander, Thank you for your comment. My apologies for missing it earlier. Your statement should be true. The thing to keep in mind is that when you start each factor (e.g., Resources, Life Expectancy, Deaths) in a Causal Loop Diagram, you assume an increase or positive in that variable. Then, the + or - outcome at the end of the arrow makes sense.

Hi Dr. Gurule, Thank you for your video. I actually have the same question and I read your response to Alexander and I am still confused. So does this mean that the CLD is incorrect and it should in fact be a (-) at the life expectancy arrow and a (+) at the deaths arrow?

Can somebody tell me useful softwares to make CLD's

Hey thankyou so much for video but i'm confused with quiz no #4. For the loop of number 5, is that reinforcing ? I think the answer is balancing because more grass can make less soil erosion and from soil erosion can make less new grass growth. Thankyou!

More grass leads to less soil erosion. Less soil erosion leeds to more grass growth. More grass growth leads to more grass. : reinforcing.

Im sorry- there is an age old saying you need to communicate at the level people can understand. These system diagrams seem to me there are lots of assumptions (a hypothetical population) that you could argue to the opposing. Understanding these should be easy and they are not. Someone has tried to make a complex causal and effect into a single diagram, and to be honest I find them more complex then simplier diagrams, so trying to get a message across with these type of diagram fails.

Good lukc trying to find a systems map maker online without being forced to pay money. Systems maps seem to be flavour of the month for university assignements to think about complex problems, their cause and effects. But if the tools aren't then provided to students to attempt to draw these, you'll find students needing to leanr a complex program in order to create one. This is a complete disconnect from learning outcomes and a failure of academics.

these assumptions like less grass leads to more cow death- not neseccarily- if the farmer feeds them more grain- then there wont be more cow death- I don't like the loose and generalised assumptions these causal diagrams make - it is wishy washy and mainly of these loops in complex systems diagrams could be argued the other way
