SLOG#3

At the beginning of studying this course, the format of typing might seem a bit strange, but it is important to get used to that format by reading through the activities each week, because if you wait until it gets difficult, you might already be lost in how to read the functions and struggling to catch up.

While doing the labs, it can also be frustrating when trying to design our own functions but it can become a great accomplishment after completing a single function.

Depending on the complexity of the function, there are certain strategies that are helpful such as:

Writing out a check-expect for what you want your function to get as outputs, then start to draft the function base on the result you want

To just start writing one function at a time and edit it as you run the function

Think about the outputs you want and set the limits in the function for the inputs as it leads to the output you need

As for the preparation for this course, because there are basically no requirements for any knowledge before getting into this class, therefore, it would be nice to have a laptop or notebook to the lectures and keep good notes. (I would recommend going to all lectures if your time permits). As long as you keep up with the lessons, you will be in good shape for this course.

Midterm 2

Need to focus my study on local and filter for lists for my final exam😂

If the first condition is false, it will go to the next. If the next condition is false, it will continue to proceed the next condition until its either true or else.

SLOG#2

After the midterm, I have started to get a bit used to how the course works and get a sense of how I should study depending on the subject. For the quizzes and tests, I prepare them by doing the activities posted every week before the tutorial and summarize the points for each new function on my notebook. The notes posted on the classes is also a really helpful tool, whenever I begin to review the notes there can always be a time when I forget how to apply a function and those notes reminds me of the correct usage of the functions.

The first image I created for practice using define to name the images is staredown and it was the one that I was most proud of. I created staredown myself using my favorite picture, it was difficult back then to understand, but as I get used to the concepts I start to know certain rules within writing an expression.

It was intimidating at first, to differentiate between map and apply, I was really confused when the lecture was given. The two function seemed similar to me, but the midterm was approaching, therefore, I needed to understand it fast and review other functions as well. I went to see the examples of both functions in the DrRacket documentation. It really helped me understand the concepts of the inputs and outputs of both functions. For now, I am fine finding my way to get the points of the concepts, but if I have any question, I might prefer trying to ask it on Piazza first then as in person to the office if I really don't understand it.

Thus is what I experiences whenever I tries to type in an expression, as for the solution, keep trying is the only way😂

Midterm

Re-write notes, try the past test, stucking the expressing onto DrRacket and see what I get next. The tiny mistakes leading to errors, and the misspelled words I usually don't do. It took days to get the things under control, please, I wish the effort and the time I put into this will give me a good result.

SLOG#1

I began to have an interest in computer science when I first know that the computers, games, and the apps we use are all programmed. It looked astonishing in the drama, with a screen full of codes and the fast-paced typing fingers which are fiction but really attractive and impressive for me. I was excited knowing that there are courses offered for studying programming and I decided to choose the course no matter what. However, I hesitated between 104 and 108  unsure whether or not I was going to master the material. At the end, I chose 104 because I want to first learn about computer science in the introductory level. I am hoping to get to know something relate to how to write certain codes making a mini game after studying the course. 

Before starting to take the lecture, I was expecting it to be something like fairy tale that everything I type will have a result coming back to me, but it is proved untrue as I randomly typing words in DrRacket. As I study the material, I get to know that programming requires definitions functions for the code to run. The order of the variables and functions I write in the code will also affect the steps and results. It is easy to get errors. I now know that programming is time consuming after my experience in the course so far. I find the defining part interesting where I can name pictures, strings, numbers, and functions. It took me some time to understand the order a code proceeds containing multiple brackets, and I think it will still be something difficult as the code becomes complicated. 

The course overall was harder than I expected. I study the quizzes from reading the notes I write in the lecture, do the lab activities stepping each of the code, and try writing the codes again myself in DrRacket. I am not really satisfied with my performance on the quizzes, I will practice writing codes and get used to writing complicated codes.I am really interested in knowing how to program games or other applications.
