WebAssign Increases Retention in Astronomy Course [Case Study] – The Cengage Blog

Keeping students enrolled in an astronomy course can feel a little like keeping a telescope steady during a windy night: the target is clear, but the conditions are not always friendly. Students arrive with different math backgrounds, different comfort levels with science, different schedules and, let’s be honest, different levels of enthusiasm for anything involving equations before 10 a.m.

That is why the Cengage Blog case study about WebAssign increasing retention in an astronomy course is worth a closer look. It is not just a “new platform, happy ending” story. It highlights a problem that many higher education instructors know too well: students do not usually leave STEM courses because they dislike the universe. They leave when the course feels confusing, rigid, disconnected or impossible to manage alongside work, family and other classes.

In the featured case study, instructor Mark Montgomery needed an online learning platform that could support both astronomy majors and non-majors. His course required online labs, accessible assignments, flexible grading tools and enough student support to prevent the dreaded academic black hole: falling behind, missing work, losing confidence and disappearing from the course roster. After adopting WebAssign, Montgomery reported a 75% decrease in his course’s drop, fail or withdraw rate, along with improved final grades and strong student feedback about ease of use.

That result matters because retention is not just a number on an institutional dashboard. In a gateway science course, retention represents students who stayed long enough to discover that astronomy is not only about memorizing planet names. It is about evidence, measurement, reasoning, data and the delightful realization that the Moon is not following them home personally.

Why Astronomy Courses Are a Retention Challenge

Introductory astronomy is one of the most fascinating general education science courses on campus, but it can also be sneaky. Students sign up expecting stars, galaxies and maybe a dramatic photo of Saturn. Then they meet light-years, spectra, orbital motion, scale models, lab data, graphs and quantitative reasoning. Suddenly, “cool space class” becomes “wait, there is math in space?”

For majors, astronomy can be a serious stepping stone into physics, engineering, data science or planetary science. For non-majors, it may be one of the few college science experiences they ever take. That makes the course important. A good astronomy class can build scientific literacy, improve confidence with data and help students understand how evidence works. A poorly supported one can confirm a student’s fear that science is for “other people.”

The retention problem often starts with friction. Students may not know where to find assignments. They may submit work late because the platform is confusing. They may get stuck on one problem and have no immediate feedback. Instructors, meanwhile, may spend hours grading, extending due dates, answering repeated technical questions and trying to identify struggling students before it is too late.

WebAssign addresses this friction by putting assignments, practice, grading, feedback, course materials and analytics in one structured environment. That sounds simple, but in online and hybrid learning, simplicity can be the difference between a student staying engaged and a student deciding the course has launched them into deep space without oxygen.

What WebAssign Changed in the Case Study

The Cengage Blog case study centers on a practical instructional need: Montgomery taught a completely online astronomy lab and needed experiments and data that students could access on their own schedule. In a traditional lab, students can gather around equipment, ask questions in real time and work through uncertainty together. Online, the course design must create that structure digitally.

WebAssign helped by offering astronomy-specific content that could support different stages of learning. Students were not simply handed a PDF and wished “good luck, brave space traveler.” They could work through interactive resources, complete online labs, practice with guided problems and receive feedback while the learning was still happening.

1. Online Labs That Fit Real Student Schedules

One of the strongest points in the case study is scheduling flexibility. Astronomy students are often juggling jobs, commutes, athletics, caregiving or other classes. A lab that can be completed only at one narrow time may become a retention barrier. WebAssign’s Virtual Astronomy Labs and related online activities allow students to interact with data and simulations at any time of day.

This matters because flexibility is not a luxury feature. It is often a persistence feature. When students can complete meaningful lab work after work, between responsibilities or during their most productive study window, they are more likely to stay on track.

2. Faster Feedback Before Confusion Becomes Panic

In STEM courses, delayed feedback can be brutal. A student who misunderstands one concept on Monday may build three more misunderstandings on top of it by Friday. By the time graded work returns, the problem has grown legs, packed a suitcase and moved into the final exam.

WebAssign gives students immediate feedback on many assignments, helping them recognize mistakes early. For astronomy, that can mean correcting a misunderstanding about scale, units, motion, graphs or observational data before it damages later learning. Feedback also helps students develop independence. Instead of waiting for an instructor to rescue them from every wrong turn, they can revise, retry and learn from the process.

3. Better Workflow for Instructors

Retention is usually discussed from the student side, but instructor workload matters too. If a platform makes grading, extensions, assignment design and student monitoring easier, instructors have more time for teaching. In Montgomery’s case, WebAssign was easier to grade in and made it easier to extend due dates than his previous platform.

That may sound administrative, but it has instructional consequences. When instructors are not buried under routine platform maintenance, they can spend more time answering conceptual questions, improving assignments and supporting students who are at risk of slipping away.

Why a 75% DFW Reduction Is a Big Deal

DFW stands for drop, fail or withdraw. In plain English, it measures how many students do not successfully complete the course. A high DFW rate is often a warning sign that students are not receiving the support, structure or clarity they need. A lower DFW rate suggests more students are making it through successfully.

A reported 75% reduction in DFW rate is significant because it points to more than improved convenience. It suggests the learning environment became easier to navigate, more supportive and better aligned with student needs. Of course, no single tool magically solves every retention problem. Teaching quality, course design, instructor communication, institutional support and student circumstances all matter. But in this case, WebAssign appears to have played a meaningful role in reducing barriers.

Think of it like a telescope mount. The mount does not create the stars, but it helps students see them clearly. WebAssign did not replace teaching; it supported teaching. That distinction is important. Technology works best when it amplifies good pedagogy rather than pretending to be the professor in a hoodie.

How WebAssign Supports Active Learning in Astronomy

Research in STEM education consistently points toward active learning, timely feedback and student-centered course design as important drivers of success. Astronomy is especially suited to this approach because the subject naturally invites exploration. Students can analyze spectra, compare planetary data, simulate motion, interpret images and test claims about the universe.

WebAssign’s astronomy tools are built around these learning moments. Animation Tutorials can help students visualize concepts that are hard to grasp from text alone. Virtual Astronomy Labs can bring data analysis into online environments. Optimized Problems can challenge students to apply concepts rather than search for copied answers. Course Packs can save instructors time when building a structured sequence of assignments.

For example, a student learning about the phases of the Moon may struggle if the concept is explained only through a static diagram. An interactive activity can let the student manipulate positions, observe changes and connect the visual model to the sky they see outside. Suddenly, the Moon is not just “doing Moon stuff.” It is following a pattern the student can explain.

Benefits for Majors and Non-Majors

A good astronomy course must serve two audiences at once. STEM majors need rigor, data skills and problem-solving practice. Non-majors need accessibility, relevance and confidence. WebAssign can support both by allowing instructors to customize assignments and blend conceptual, quantitative and lab-based work.

For majors, the platform can reinforce habits that matter beyond astronomy: reading graphs, checking units, interpreting evidence and solving multi-step problems. For non-majors, it can reduce intimidation by breaking complex ideas into manageable learning steps. That balance is one reason the case study is useful for instructors beyond astronomy. The same retention logic applies in physics, chemistry, math, statistics and other demanding courses.

Affordability and Access Matter Too

Retention is not only academic. Cost and access shape whether students stay enrolled. WebAssign includes options that can pair with lower-cost materials, including open educational resources in some courses. It also integrates with learning management systems such as Canvas, Blackboard, Brightspace, Moodle and Sakai, helping students avoid the “Where do I click now?” scavenger hunt that turns simple homework into a campus-wide detective drama.

When access is streamlined, students are more likely to start assignments on time. When course materials are easier to reach, they are more likely to use them. When the platform is predictable, students can spend less energy navigating technology and more energy learning why Jupiter has so many moons and apparently no sense of moderation.

What Instructors Can Learn from This Case Study

The first lesson is that retention improves when course design removes unnecessary obstacles. Students should still be challenged by astronomy, but they should not be challenged by confusing navigation, delayed feedback or avoidable administrative friction.

The second lesson is that online labs need intentional structure. A strong online lab is not a worksheet wearing a space helmet. It should involve data, inquiry, feedback and clear expectations. WebAssign’s astronomy content gives instructors a way to build that structure without creating every activity from scratch.

The third lesson is that student feedback matters. In the case study, students responded positively to WebAssign’s ease of use. That is not a small detail. If students find a system frustrating, they may disengage even when the content is strong. A platform that feels intuitive can support motivation because students feel capable before they even begin the assignment.

Practical Examples of WebAssign in an Astronomy Course

Imagine a module on stellar brightness. Students begin with a short reading and an animation explaining apparent magnitude and luminosity. Then they complete a WebAssign activity using simulated star data. They answer questions, receive immediate feedback and revise mistakes. The instructor reviews analytics and notices that many students missed questions involving inverse-square reasoning. The next class announcement includes a quick clarification and a practice problem.

Or picture an online lab on exoplanet detection. Students analyze light curves to identify possible transits. Instead of passively reading about planets crossing stars, they work with data patterns. They make predictions, test interpretations and learn why tiny dips in brightness can reveal worlds beyond our solar system. That kind of activity gives students a reason to persist because the work feels like discovery, not digital paperwork.

Experience Notes: What This Looks Like in Real Teaching and Learning

From a teaching experience perspective, the biggest value of a platform like WebAssign is not that it makes astronomy “easy.” Astronomy should still stretch students. The real value is that it makes the work more visible. In a traditional setup, an instructor may not know a student is lost until the first major exam. By then, the student may already be mentally packing up and heading for the academic escape pod. With online homework, topic-level performance and assignment data, instructors can spot patterns earlier.

For students, the experience can feel more manageable because the course has a rhythm. They log in, see what is due, work through guided problems, receive feedback and know where to ask for help. That structure is especially important for online learners, who may not have the casual reminders that happen before and after an in-person class. In a digital course, silence is dangerous. A good platform creates touchpoints that keep students connected.

Another experience worth noting is confidence-building. Many students enter astronomy with curiosity but not confidence. They may love NASA images but panic when asked to interpret a graph. When assignments offer immediate feedback and multiple opportunities to practice, students can improve without feeling publicly embarrassed. That private trial-and-error process matters. It turns mistakes into learning events instead of identity statements like “I am bad at science.”

For instructors, WebAssign can also reduce repetitive tasks. Extending a due date, copying an assignment, adjusting settings, reviewing submissions and checking student progress can become less time-consuming. That saved time can be reinvested in better announcements, clearer examples, short review videos or targeted outreach. In other words, automation can make the course feel more human when instructors use the extra time to communicate.

The most successful experience, however, comes when WebAssign is not treated as a storage closet for homework. It should be part of a learning strategy. Instructors can preview common mistakes before an assignment, use results to plan review sessions and connect online labs to real-world astronomy news. A unit on eclipses can connect to current sky events. A lab on spectra can connect to how scientists study exoplanet atmospheres. A module on scale can include the classic reminder that space is not merely big; it is “your group project file size after everyone adds images” big.

Students also benefit when expectations are explicit. Tell them why the assignment matters, how much time it should take and what to do if they get stuck. Encourage them to use feedback rather than click randomly until the platform surrenders. Remind them that persistence in STEM often grows through repeated practice. The goal is not to get every answer instantly correct. The goal is to become the kind of learner who can recover from confusion.

That is the deeper message of the case study. Better retention did not happen because students were entertained into passing. It happened because the learning environment gave them a better chance to stay organized, practice meaningfully and receive support at the right time. In an astronomy course, that is a beautiful outcome. After all, the universe is already hard enough. The homework platform does not need to be another celestial hazard.

Conclusion

The Cengage Blog case study on WebAssign and astronomy retention shows how thoughtful educational technology can support student success when it is matched with real teaching needs. Mark Montgomery needed a platform that could make online astronomy labs practical, flexible and engaging. WebAssign helped him deliver that experience, and the reported 75% reduction in drop, fail or withdraw rate suggests that students benefited from the change.

For instructors, the takeaway is clear: retention improves when students receive structure, feedback, flexibility and meaningful practice. For students, WebAssign can make astronomy feel less like a maze and more like a guided exploration of the universe. For institutions, the case study offers a reminder that course-level improvements can support broader goals around persistence, completion and STEM confidence.

Astronomy is a course about looking outward, but this case study asks educators to look inward at course design. Are students getting feedback early enough? Are online labs truly interactive? Is the platform helping or hindering learning? Are instructors spending their time on teaching or troubleshooting?

When those questions are answered well, students are more likely to stay in the course, earn stronger grades and leave with a better understanding of science. And if they also stop thinking Mercury is in retrograde every time their homework is late, that is a bonus for civilization.
