Easier Coding Assignment Creation with Solution Templates & Code Freezing

When testing auto-graded coding assessments, it’s easy to forget to remove the solution coding lines from the starter code file before publishing..

Then, with one click, students have a fully completed coding assessment! This defeats the purpose of helping them to learn to code by creating their own solutions to computer programming assignments. This is a common problem faced by computer science educators and trainers who use auto-graded assignments.  This becomes even more likely when you go back to check old assignments with coding or have newer authors, such as TAs, helping build the course. Now, Codio lets you automatically use Solution Templating to remove coding lines with solutions from starter code files for your online course. This ensures that students will not be able to access the coding lines with solutions to the coding assignment. Additionally, when authoring coding assessments and programming homework, it is common to want coding lines inside the student's file that interfaces with auto-graders that you don’t want students to change. While surrounding the code with DO NOT EDIT comments helps – Codio now lets you freeze lines of code so students cannot edit them. This is now more important as it gives educators full control over the student’s coding environment and creation code. This makes sure that vital parts of the starter code are not edited so the auto-grading still works and the assignment can accurately test the knowledge of students.

Solution Templating: Automatically Remove Solutions from Starter Code Files

To indicate where a solution is within a code file, simply add a ‘Codio Solution Begin’ comment before the solution coding lines and a ‘Codio Solution End’ comment at the end of the solution coding lines.

When the assignment is published, the student sees the following in the code file:

While the above example is in python, solution templating works in a variety of programming languages:

• HTML / CSS / JS

You can see the complete list of file extensions supporting solution templating in our documentation .

Solution templating can be used more than once in a file – for example, if you want students to complete a number of Java methods but you want the method headers declared for them:

When the student opens the assignment, they see:

It is important to note that the publishing process removes these coding lines with solutions – so when teachers and TAs are in a student’s assignment to provide help or grade, these solutions will not be visible. This helps maintain the integrity of the assignment.

To provide a solution or any other help or grading information to teachers or TAs within a student’s assignment, you can use a guidance call-out block or a separate teacher-only page .

Freezing Lines of Code so Students Cannot Change Starter Code

When using Codio’s script-less code auto-grader, coding lines are  frequently included as part of the starter code to parse keyboard input or command line arguments into a student-ready format. Currently, many content authors try their best to clearly communicate not to edit this code to the student through comments :

Instead of relying on students reading and following directions, teachers can now freeze lines of code that the auto-grader relies on. Similar to Solution Templating, simply add a ‘FREEZE CODE BEGIN’ comment before the lines to be frozen and a ‘FREEZE CODE END’ comment at the end of the lines to be frozen. The example above would then look like this:

You can see the complete list of file extensions supporting freezing lines of code in our documentation .

You can also have multiple sections of frozen code within the same code file. For example, you can freeze the entirety of the starter creation code:

Better Together: Combining Solution Templating and Code Freezing

Solution templating and code freezing can be combined in a single code file to ensure that the solution does not get passed to students and that students do not edit code that connects to the auto-grader. For example:

Will be presented to the student as follows:

Create Better Coding Assignments with Codio

It doesn’t matter if you teach coding for beginners, coding languages or development processes for programming experts, you need a solution that can help you to assess your computer science students fairly. Autograders are designed to assess the coding skills of computer science students while minimizing the manual work for educators and trainers. If the integrity of the assignments are compromised because coding lines with solutions are readily available, then students won’t be graded based on their own skills. The true mark of a thorough assessment is the integrity and fairness of its grading. Educators should have to do double the work to ensure their assessments reveal coding lines with solutions or that coding problems can be edited accidentally. This is why Solution Templating and the ability to code freeze-specific sections are so important.  It makes the planning creation process of assignments much easier, especially among teams. All in all, this simplifies the grading process and reduces the time to go back and check for errors in coding lines. You can foster learning by having students work directly in online environments like Python fiddles to create solutions. Let Codio help you deliver a better user experience with your computer science courses with easy coding environments.  Get Started Today - schedule a demo, create a free instructor account .

Restart or Reset Box ¶

You can restart or reset your project’s box from the Project menu.

To restart the box, click the Project tab and choose Restart Box . The reboot normally takes a few seconds.

Resetting a box is fairly destructive and should be used with caution. When performing a box reset, the box is returned to a fresh state but your code files are untouched. It also results in the following:

Any new folders or files that have been created will be deleted.

All parts of the box outside the ~/workspace folder will be reset.

All code files in the ~/workspace folder are untouched.

Box restart.

After a Reset, you must reinstall components (npm modules, ruby gems, etc.) and other modifications you may have made.

Students want to recover a deleted file which got deleted accidentally.

If you delete a file in an error, you can use the Code Playback option to find that file. Please follow the below steps to recover a deleted file:

Open the assignment then go to Tools -> Code Playback .

Click on the folder icon.

Find the file which you have deleted.

Review the file and it will show how it was built

You can find your last saved work by clicking on the Previous change , Play/Pause, and Next change buttons (from left to right) or by dragging the timeline bar along

You can create a new file and copy/paste from the code playback into a new file that you created.

Note: If you don't have Tools -> Code Playback , right-click on a tab or in the file tree and select Code Playback

Rating Action Commentary

Fitch Assigns Arbour CLO XI DAC Reset Notes Expected Ratings

Mon 20 May, 2024 - 11:57 AM ET

Fitch Ratings - London - 20 May 2024: Fitch Ratings has assigned Arbour CLO XI DAC reset notes expected ratings, as detailed below.

The assignment of final ratings is contingent on the receipt of final documents conforming to information already reviewed.

• Class A-R Loan
• Class B-1R Notes
• Class B-2R Notes
• Class C-R Notes
• Class D-R Notes
• Class E-R Notes
• Class F-R Notes

VIEW ADDITIONAL RATING DETAILS

Transaction Summary

Arbour CLO XI DAC is a reset securitisation of mainly senior secured obligations (at least 90%) with a component of senior unsecured, mezzanine, second-lien loans, first-lien, last-out loans and high-yield bonds. The note proceeds will be used to redeem the existing notes (except the class M and subordinated notes) and to fund a portfolio with a target par amount of EUR500 million, which is actively managed by Oaktree Capital Management (Europe) LLP. The transaction will have a 2.5-year reinvestment period and a 6.5-year weighted average life test (WAL) at closing.

KEY RATING DRIVERS

Average Portfolio Credit Quality (Neutral): Fitch assesses the average credit quality of obligors to be in the 'B'/'B-' category. The Fitch weighted average rating factor (WARF) of the identified portfolio is 25.95.

High Recovery Expectations (Positive): At least 90% of the portfolio will comprise senior secured obligations. Fitch views the recovery prospects for these assets as more favourable than for second-lien, unsecured and mezzanine assets. The Fitch weighted average recovery rate of the identified portfolio is 61.0%.

Diversified Portfolio (Positive): The transaction will have two matrices effective at closing corresponding to the 10 largest obligors at 20% of the portfolio balance and two fixed-rate asset limits at 7.5% and 15% of the portfolio. The transaction also includes various concentration limits, including the maximum exposure to the three-largest Fitch-defined industries in the portfolio at 40%. These covenants ensure that the asset portfolio will not be exposed to excessive concentration.

Portfolio Management (Neutral): The transaction will have a 2.5-year reinvestment period and includes reinvestment criteria similar to those of other European transactions. Fitch's analysis is based on a stressed-case portfolio with the aim of testing the robustness of the transaction structure against its covenants and portfolio guidelines.

Cash Flow Modelling ( Positive ): The WAL used for the transaction stress portfolio and matrices analysis is six years. This reduction to the risk horizon accounts for the strict reinvestment conditions envisaged by the transaction after its reinvestment period. These include, among others, passing both the coverage tests and the Fitch WARF test post reinvestment as well a WAL covenant that progressively steps down over time, both before and after the end of the reinvestment period. Fitch believes these conditions would reduce the effective risk horizon of the portfolio during the stress period.

RATING SENSITIVITIES

Factors that could, individually or collectively, lead to negative rating action/downgrade.

A 25% increase of the mean default rate (RDR) across all ratings and a 25% decrease of the recovery rate (RRR) across all ratings of the identified portfolio would have no impact on the class A-R notes and would lead to downgrades of no more than two notches for the class B-R to F-R notes.

Based on the current portfolio, downgrades may occur if the loss expectation is larger than initially assumed, due to unexpectedly high levels of defaults and portfolio deterioration. Due to the better metrics and shorter life of the current portfolio than the Fitch-stressed portfolio, the class F-R notes display a rating cushion of three notches, the class B-R, D-R and E-R notes of two notches and the class C-R notes of one notch.

Should the cushion between the current portfolio and the Fitch-stressed portfolio be eroded either due to manager trading or negative portfolio credit migration, a 25% increase of the mean RDR across all ratings and a 25% decrease of the RRR across all ratings of the stressed portfolio would lead to downgrades of up to four notches for the notes.

Factors that Could, Individually or Collectively, Lead to Positive Rating Action/Upgrade

A 25% reduction of the mean RDR across all ratings and a 25% increase in the RRR across all ratings of the Fitch-stressed portfolio would lead to upgrades of up to three notches for the rated notes, except for the 'AAAsf' rated notes, which are at the highest level on Fitch's scale and cannot be upgraded.

During the reinvestment period, based on the Fitch-stressed portfolio, upgrades may occur on better-than-expected portfolio credit quality and a shorter remaining WAL test, leading to the ability of the notes to withstand larger-than-expected losses for the remaining life of the transaction. After the end of the reinvestment period, upgrades may occur on stable portfolio credit quality and deleveraging, leading to higher credit enhancement and excess spread available to cover losses in the remaining portfolio.

USE OF THIRD PARTY DUE DILIGENCE PURSUANT TO SEC RULE 17G -10

Form ABS Due Diligence-15E was not provided to, or reviewed by, Fitch in relation to this rating action.

DATA ADEQUACY

Fitch has checked the consistency and plausibility of the information it has received about the performance of the asset pool and the transaction. Fitch has not reviewed the results of any third party assessment of the asset portfolio information or conducted a review of origination files as part of its ongoing monitoring.

The majority of the underlying assets or risk presenting entities have ratings or credit opinions from Fitch and/or other Nationally Recognized Statistical Rating Organizations and/or European Securities and Markets Authority registered rating agencies. Fitch has relied on the practices of the relevant groups within Fitch and/or other rating agencies to assess the asset portfolio information or information on the risk presenting entities.
