Parameterized assessments

For all assessment types except Gradebook and Random, you can set up parameterized assessments by writing python code on the Parameters tab.

Parameterized Assessment

For more information and to get started, see Prairielearn for the popular implementation.

Setting up parameters

To set up your parameters, create them using codio_parameters[“parameter name”] = yourparamevalue on the Parameters tab and you can then refer to them throughout the assessment within double curly brackets.

e.g. creating a parameter of codio_parameters[“parameter name”] = random_int, you can then refer to {{parameter name}} in your assessment. This can be in the instructions on the General tab, in fields on the Execution tab as well as in the rationale on the Grading tab.

Parameter variables

We are not using global variables but explicitly storing parameter values in a dictionary. Here is an example:

import random
import uuid

# init codio_parameters dictionary
codio_parameters = dict()

# generate random values
random_int = random.randint(0, 100)
random_string = str(uuid.uuid4())
random_boolean = random.choice([True, False])
random_float = float(random.randint(0, 1000)/100)
random_array = []
random_array.append(random.randint(0, 100))
random_dict = dict()
random_dict["int"] = random.randint(0, 100)
random_dict["str"] = str(uuid.uuid4())
random_dict["boolean"] = random.choice([True, False])

# add random values to codio_parameters dictionary
codio_parameters["int"] = random_int
codio_parameters["str"] = random_string
codio_parameters["boolean"] = random_boolean
codio_parameters["float"] = random_float
codio_parameters["array"] = random_array
codio_parameters["dict"] = random_dict
