Recently I pointed out that the widely-quoted Babson survey on online learning estimates 7.1 million US higher ed students taking at least one online course while the new IPEDS data indicates the number as 5.5 million. After looking deeper at the data, it appears that the difference in institutions (whether or not an institution offers any online courses) is even greater than the difference in students. This institutional profile is important, as the Babson report (p. 13) noted that institutions offering no online courses had very different answers than others, a theme that ran through much of the report: [emphasis added]

The results for 2013 represent a marked change from the pattern of responses observed in previous years. In the past, all institutions have consistently shown a similar pattern of change over time. Different groups of institutions typically reported the same direction of change – if one group noted an improvement on a particular index, all other groups would show a similar degree of improvement. The overall level of agreement with a particular statement might vary among different groups, but the pattern of change over time would be similar. This is not the case for 2013.

As noted above, there was a year-to-year change in the overall pattern of opinions on the strategic importance of online education, and on the relative learning outcomes of online instruction, as compared to face-to-face instruction. In both cases, the historic pattern of continued improvement took a step back for 2013, and all of the changes are accounted for in a single group of institutions: those that do not have any online offerings.

Institutions with no online offerings represent a small minority of higher education – how are they different?

Let’s look at the IPEDS data on institutions versus the Babson data, first by institutional control. I took the data on page 32 of the Babson report and recreated the graph, then I ran the same analysis using IPEDS data. (NOTE: these interactive charts do not come through on RSS feeds, so you probably will have to click through to post to see.) (more…)

Update: I should have guessed this, but the visualizations don’t come through on RSS feeds, so you’ll need to click through to the article.

Reader Mike Himmelstein has rightly pointed out that our analysis of the new IPEDS data would benefit from using visualization tools instead of just tables. This comment led me to a multi-day investigation of which data visualization tool would best integrate into a WordPress blog while maintaining interactive data exploration. I tried MicroStrategy (great tool but cannot share without login), IBM Many Eyes (good public tool but limited in formatting), and several variations of Google Charts (not as rich in features as MicroStrategy, but close, and supports public sharing). In the end I’ve ended up using the Visualizer plugin to display Google Charts. All data below is for degree-granting institutions.

Let’s first look at the state-by-state data in a Geochart. This data tracks online ed in public higher ed institutions as of Fall 2012. I’m showing the data broken out by undergraduate and graduate students. The color scale is based on the percentage of students taking at least one online course, but if you hover over a state you can also see the percentage of students taking all of their courses online.

For the basic data combining undergraduate and graduate students in a table format, see this post.

I’ve written several posts recently looking at the new IPEDS data on distance education (for the most part equivalent to online education). In one post I pointed out [emphasis added]:

Previously, the best data available on total student counts came from the Babson Survey Research Group with their annual survey (prior to 2012 called the Sloan survey). This is the survey tracking the total number of students taking at least one course online. When I talked to the researchers earlier this year, they mentioned that they hoped the new IPEDS data would ‘put them out of business’. I hope this comment was half in jest, as their survey measures much more information than just total student counts and they have very useful longitudinal data. I have asked BSRG for an updated statement on their plans but have not been able to get a response yet.

Some additional notes on the data:

According to the IPEDS data, 5.5 million (26%) degree-seeking students in the US took at least one online course in Fall 2012, which is significantly less than that reported by Babson (6.7 million / 32% for Fall 2011 data). Keep in mind the different methodologies involved – IPEDS collects data reported directly from colleges and universities, while Babson is based on a representative survey; IPEDS measures “distance education”, while Babson measures “online courses”. I would look forward to this year’s Babson survey to explain the differences, but for now, I’ll just note the difference.

The new Babson Survey came out yesterday morning, and I was disappointed to find out that they did not address or acknowledge the differences in the data. With the new survey data (p. 15, using Fall 2012 data just like IPED), they came to a dramatically different conclusion [emphasis added]:

It’s Tuesday, so it must be time for my daily post on the new IPEDS data including online education. There are so many ways to slice this data that just was not possible before, and with a little spreadsheet engineering, I’m finding it easy to come up with new views. Today let’s look at the adoption of online education per state for public institutions (both 4-year and 2-year schools). Note that this data does not include private non-profit or for-profit institutions as I wanted to focus on official state involvement in online ed.

IPEDS tracks information now about students taking exclusively distance education courses, students taking some but not all distance education courses, and students not taking any distance education courses. Please note the following:

• I am using the terminology “online courses” rather than “distance education”. For the most part these terms are interchangeable, but they are not equivalent as “distance education” can include courses delivered by a medium other than the Internet (e.g. correspondence course). Part of the reason I stick with “online course” is that there is a growing use case where students local to a campus choose to take a course online, which is not really at a distance.
• I have combined the fields for students taking “exclusive online courses” and “some but not all online courses” to derive the “at least one online course”, as this roughly equals the data reported by the Sloan survey / Babson Survey Research Group survey.

Last week I mentioned how the National Center for Educational Statistics (NCES) and its Integrated Postsecondary Education Data System (IPEDS) are now providing preliminary data for the Fall 2012 term that for the first time includes online education. Let’s look at a profile of online education in the US for degree-granting colleges and university, broken out by sector and undergrad / grad  degrees.

IPEDS tracks information now about students taking exclusively distance education courses, students taking some but not all distance education courses, and students not taking any distance education courses. Please note the following:
