Three sources on math placement, each checked by reading about its author and funder elsewhere, are judged in the Unit 4 source evaluation exercise for CM220 shown here. Searches like "cm 220 unit 4 assignment example", "cm220 unit 4 sample" and "cm220 unit 4 example" land here.
What a finished CM220 Unit 4 source evaluation exercise looks like
About three pages, one section per source, with a summary table at the end. The first source is a national advocacy organization's brief reporting large gains from corequisite placement; lateral reading shows the organization's stated mission is ending prerequisite remediation and that foundations with that goal fund it, and the exercise traces two of its headline figures back to the state reports they came from. The second is a news feature quoting a college president; checking shows the college had recently adopted the model and was promoting it. The third is a faculty association statement whose authors are experienced instructors but which cites no outcome data. Each section records the checks run, what they showed, and a verdict on how the source may be used. The table compresses those verdicts into a single page.
How a CM220 Unit 4 example is structured
Many CM220 prompts supply an evaluation framework, and the example uses the four moves often taught as SIFT: stop, investigate the source, find better coverage, and trace claims to their original context. Each source section follows those moves in order, reporting what was done and found rather than restating the framework. Investigating the source means reading what others say about the organization, not what it says about itself. Finding better coverage means checking whether reputable outlets or researchers report the same finding. Tracing means following a statistic to its origin and confirming it was quoted accurately. A verdict closes each section in two parts: what the source can support and what it cannot. The summary table lists source, producer, interest, evidence quality and permitted use, and a closing paragraph explains how the exercise changed two annotations from Unit 3.
Reading about the source, not from it
The advocacy brief's own About page describes neutral research. Searching the organization's name elsewhere shows its policy goals and funders. The exercise records both and explains why the second view governs.
A statistic traced home
The brief's headline gain appears in a state system report, but for one college year and one course. The exercise notes the brief reported it without either limit, and restricts its use accordingly.
An interest disclosed, not a disqualification
The college president quoted in the news feature has a reason to promote the model. The verdict keeps the feature for its student interviews and drops its outcome claims.
Experience without data
The faculty association writes from classroom experience but cites no outcomes. The exercise treats its statement as evidence of a concern held by practitioners, not as evidence about results.
Verdicts in two parts
Every source ends with what it can support and what it cannot. That split keeps useful material in the essay while preventing any source from carrying more weight than its evidence allows.
Where marks go in CM220 Unit 4
Surface signals are the trap in this exercise. A source judged reliable because its website looks professional, ends in .org, or has a named author has not been evaluated in the sense the exercise means, and many rubrics say so. The all-or-nothing verdict comes next: a source declared unusable because it has an interest, when the stronger move is to say what it can and cannot support. Claims left untraced, where a brief's statistic is accepted without checking its origin, cost points in sections using a lateral reading framework. Evaluations that summarize the sources' content at length instead of examining them miss the task. A missing summary table or framework, where required, is a routine loss. Citations still count here, and APA 7 errors in the source list draw small deductions.
Get a CM220 Unit 4 example written to your instructions
Pick the sources you are least sure of, or use any your CM220 Unit 4 prompt assigns, and pass them along with the evaluation framework and rubric. Each is checked laterally, traced back wherever it cites figures, and given a two-part verdict on what it can and cannot support, all within 24-48h. First custom samples are free.
CM220 Unit 4 questions, answered
What is lateral reading?
Checking a source by leaving it and seeing what other sources say about its author, publisher or funder, rather than judging it from its own pages. Professional fact-checkers work this way, and many composition courses now teach it through frameworks such as SIFT. In an exercise like this one, the write-up reports what was searched and what turned up.
Is a source with an agenda automatically unreliable?
No. Most sources have some interest, and advocacy organizations often publish useful data. The evaluation question is how that interest might shape what the source reports and which of its claims can be checked independently. A strong exercise keeps such a source for what can be verified and says plainly where its interest limits it.
How is this different from the annotated bibliography?
The bibliography evaluates each source briefly as part of a list. This exercise goes deeper on fewer sources, recording the checks performed and what they revealed. Many CM220 sections use it to test the method itself, so the process matters as much as the verdict, and the results often lead to revised annotations.
