Sharing assignments in OpenClass
OpenClass is on a mission to improve & democratize education. Through our platform, educators can share assignments privately or with our entire community to improve accessibility of the best learning resources around the world.
Our assignments guide students through research-backed study sessions to reinforce learning. If this review is relevant to your teachings, feel free to add it to one of your classes!
Our format is simple and engaging: students are asked a retrieval question, then shown corrective feedback and a multiple-choice mastery question to assess their understanding of the material. Assignments adapt to unique student needs and continue to draw questions until a student has demonstrated mastery.
Imagine you are creating a simple text-based game where the player can collect coins. Write a Python snippet that initializes a variable to store the number of coins a player has, increases the number of coins by 10, and then prints the total number of coins.
Consider a scenario where you need to keep track of the number of times a button is clicked in a web application. Write a Python function that uses a global variable to count the number of clicks and returns the updated count each time the function is called.
Calculate the area of a rectangle using variables.
Calculate the average of three numbers using variables.
Imagine you are creating a simple program to track the number of books you read each month. Write a JavaScript snippet to declare a variable that will store the number of books read in January. Explain why you chose the specific type of variable declaration.
You are tasked with creating a program that calculates the total cost of items in a shopping cart. Write a JavaScript snippet to declare a variable that will store the total cost, and explain your choice of variable declaration.
You are developing a game where players collect points. Write a JavaScript snippet to declare a variable that will store the player's score, and explain your choice of variable declaration.
Declare and initialize a variable to store your favorite color.
Create a variable to store the sum of two numbers.
Use a variable to store a greeting message.
You are collaborating on a project and need to incorporate changes from a remote branch into your local branch. Describe the Git command you would use and explain how it works.
You have been working on a feature branch and are ready to integrate your changes into the main branch. Describe the Git command you would use to merge your feature branch into the main branch and explain any potential conflicts that might arise.
You want to create a new branch to experiment with a new feature without affecting the main codebase. Describe the Git command you would use to create and switch to this new branch, and explain why branching is useful in Git.
Creating a Simple HTML List
Creating a Hyperlink in HTML
Imagine you are creating a simple webpage for a local bakery. Describe how you would use HTML elements to structure the page, including a header, a list of bakery items, and a footer with contact information.
Imagine you are designing a simple webpage for a local library to display a list of available books. Describe how you would use basic HTML elements to create a structured list of books, including the title, author, and genre for each book. Consider how you would organize this information to make it clear and accessible to users.
You have been working on a feature branch and are ready to integrate your changes into the main branch. Describe the Git command you would use to merge your feature branch into the main branch and explain any potential conflicts that might arise.
(Student response here)
To merge a feature branch into the main branch, you would use the `git merge` command. First, switch to the main branch using `git checkout main`, then execute `git merge <feature-branch>`. This command combines the histories of the two branches. Conflicts may arise if changes in the feature branch overlap with changes in the main branch. Git will pause the merge and mark the conflicting files, requiring manual resolution before completing the merge.
git checkout main (switch from feature_branch back to the main)
git merge feature_branch (merge feature_branch into main)
A potential conflict that might arise would be if someone has changes to the same code on a different branch. A choice would have to be made between the two changes.
git checkout main (to make sure we are in the main branch)
git switch main
git pull origin main
git merge feature_branch
git push origin main
git checkout feature_branch
Make sure your'e on the main branch by running git checkout main/ git switch main. Update the main branch by using git pull origin main, merge the feature branch using the git merge feature-branch and then replace feature-branch with the actual name of your branch. The potential conflicts may arise if the both the main branch and the feature branch have modified the same lines in a file or if a file has been deleted in one branch but modified in another.
When resolving a merge conflict in Git, what is the purpose of the conflict markers (e.g., `<<<<<<<`, `=======`, `>>>>>>>`)?
They delete the conflicting lines from both branches.
They automatically resolve the conflict by choosing the most recent change.
They indicate that the merge was successful without conflicts.
They indicate the conflicting changes from each branch, helping you decide how to resolve the conflict.
