TUTOR is a programming language developed in the 1960s for use with the PLATO system at the University of Illinois. It was designed specifically for computer-assisted instruction and online courseware creation, allowing educators to create interactive lessons without needing extensive programming knowledge. TUTOR is known for its simple syntax and direct commands that facilitate creating complex educational software. Its features include support for graphics, multiple choice questions, fill-in-the-blank exercises, student tracking capabilities and more. However, it's largely obsolete today due to advancements in technology and newer languages better suited to modern systems.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with TUTOR.

What does the following Python code do?
def square(num):
    return num ** 2
This code defines a function named 'square' that takes an input 'num' and returns its square by using the power operator '**'.
What will be the output of the following Python code?
print('Hello, {}'.format('World'))
The output of this code will be 'Hello, World'. The '{}' is a placeholder that gets replaced by 'World' due to the format function.
What does the following Python code do?
numbers = [1, 2, 3, 4, 5]
squares = [n**2 for n in numbers]
This code creates a new list 'squares' that contains the square of each number in the 'numbers' list. This is done using list comprehension.
What does the following Python code do?
import threading

def print_numbers():
    for i in range(10):
        print(i)

def print_letters():
    for letter in 'abcdefghijklmnopqrstuvwxyz':
        print(letter)

thread1 = threading.Thread(target=print_numbers)
thread2 = threading.Thread(target=print_letters)

thread1.start()
thread2.start()
This code creates two separate threads that execute concurrently. The first thread executes the 'print_numbers' function and the second thread executes the 'print_letters' function.

Wrap-up questions

Final candidate for TUTOR Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle TUTOR application deployments.

How would you use Tutor to integrate an Open edX platform with a third-party service?

You can use Tutor to integrate an Open edX platform with a third-party service by creating a new plugin that adds the necessary configuration to the platform.

What are the steps to create a new Tutor plugin?
