Wolfram Computation Meets Knowledge

Online Enrichment with Free Daily Study Groups

Online Enrichment with Free Daily Study Groups

Students are spending countless hours online for classes this year, pushing educators to offer more engaging and worthwhile virtual content. We debuted Wolfram Daily Study Groups in early April with this in mind, and the results have far surpassed our expectations! Throughout this ongoing program, we’ve been able to keep students, professionals and lifelong learners engaged and connected in an enriching online community. With several Study Groups completed, and more in the works, we thought we’d share some of our successes so far.

How Do Study Groups Work?

The idea is pretty simple: one- to four-week topical programs made up of daily hourlong sessions Monday through Friday. Study Groups feature fun, directed, incremental learning resources. An instructor guides each session by sharing lesson videos, polling the group to review key concepts, introducing practice problems and answering questions.

Highly motivated attendees can demonstrate their newly honed skills by completing autograded quizzes (deployed to the Wolfram Cloud, of course!) and earn certificates of completion. To date, four hundred Study Group participants have earned these certificates that can be shared on college applications, resumes and CVs and posted to LinkedIn profiles.

Start at the Beginning: Introduction and Fundamentals

Our inaugural Study Group started with—you guessed it—a primer on the Wolfram Language. Video lessons were borrowed from Stephen Wolfram’s course An Elementary Introduction to the Wolfram Language. During progressive daily sessions over four weeks, participants built skills by writing their first programs in the Wolfram Language, doing computations and visualizing data. Our poll results showed that different members of the group had a range of plans for their new skills:

How would you like to use the Wolfram Language?

Rory Foulger, instructional designer and technologist in our Outreach & Communications department, led this Study Group, bringing practical teaching experience from various Wolfram student outreach programs. Each week on Friday, Rory introduced fun mini-project activities that provided a recap of topics from that week. In one of the projects, the group applied what they had learned about defining variables and manipulating lists in the Wolfram Language to generate random slot machine (AKA fruit machine) results:

In a mini-project from the final week of this introductory program, participants used geographic functionality to explore the well-known traveling salesman problem by creating a map of the shortest tour connecting all African countries:

Building Skills, Exploring More Courses and Certifications

Daily Study Group sessions during the month of May were devoted to more advanced programming concepts. Wolfram certified instructor Jayanta Phadakar presented lessons on functions, expressions, patterns and package development, among other topics. The Programming Fundamentals series was our most popular Study Group, with over three thousand participants during the month. This extensive program required an extended commitment from participants, with almost 10% successfully completing assigned exercises to earn Level I Certification in Wolfram Language Programming Fundamentals.

Level I Certification in Wolfram Language Programming Fundamentals

In June and July our Study Groups branched out to dive into topics from Wolfram U interactive courses including Introduction to Notebooks, Introduction to Image Processing and Multiparadigm Data Science. Wolfram U course authors and veteran instructors Dave Withoff and Abrita Chakravarty provided insights from their courses and encouraged everyone to take the full interactive courses and pursue the certifications available there.

This Study Group represented an interesting mix of members, attracting more academic and business professionals and fewer students than our previous groups:

Which best describes you?

We were impressed by the interaction among the diverse participants, who learned a lot by helping each other work through problems. Many attendees agreed that these informal discussions taking place on Wolfram Community and in the Study Group chat provided invaluable perspective that helped them further solidify their understanding of the concepts.

Special-Interest Study Groups: Mathematics, Modeling and Analysis

The remainder of the 2020 Daily Study Groups have been devoted to specific topics in mathematics, modeling and COVID-19 data analysis. The three-week calculus group was scheduled just prior to the start of the new school year in August and proved to be our second most popular group. Many group members were interested to learn calculus functionality, of course, but others used the Study Group to explore teaching techniques and methods for supporting their students.

What is your primary motivation for attending this calculus Study Group?

Our linear algebra Study Group just wrapped at the end of October, advancing our progression of mathematics topics. We hope to cover more math material in future sessions. (Until then, check out self-study math courses from Wolfram U.)

System modeling was the focus of another Study Group in September. We were surprised to see in our first-day poll that 87% of the group entered with little to no prior knowledge of the subject:

How familiar are you with modeling?

The challenge for our instructors was to offer a full range of examples and topics to cater to different interests and experience levels. Their efforts paid off; at the end of the weeklong program, our poll showed that every category was useful to at least some of our participants:

Which topics from this Study Group were most useful to you?

Our subsequent data analysis Study Group focused on computations using publicly available COVID-19 epidemic data from the Wolfram Data Repository. This Study Group expanded on the fast-paced lessons from the similarly named Wolfram U video course, taking time to explain concepts and field questions from the group.

Up Next: Machine Learning… Then Start Again!

Heading into the final two months of the year, we have time to squeeze in a couple more Daily Study Groups. We’re having too much fun to stop now!

Machine learning in the Wolfram Language is a topic that is in high demand, and we have plans for two new groups. The first will spend a week in November covering machine learning basics such as supervised and unsupervised learning, neural networks and the built-in machine learning functions in the Wolfram Language. The second group will follow this introductory week and will feature explorations in biodiversity using machine learning.

We’ll continue Daily Study Groups in 2021, starting fresh with a reprise of introductory Wolfram Language topics. We’re also planning to explore bundles of the beautiful new workflows featured in Wolfram Language documentation on topics from data analysis to API deployment, as well as the tremendous catalog of training material in our Wolfram U archives. Visit Wolfram U to browse our collection of self-directed courses and available certifications.

With all this new material, we have a little something for everyone. So sign up for one of our upcoming Daily Study Groups, check out the archived content from our previous sessions and let us know if you have any suggestions for topics. We hope to see you soon—and until then, never stop learning!


Special Thanks

At Wolfram, we’re fortunate to be surrounded by colleagues with specialized fields of interests and experience in academia and teaching. We’re thankful for all the Study Group instructors and teaching assistants who have helped us to provide such a rich resource to so many, and we’re inspired by the folks from all sorts of backgrounds, from all around the world, who have participated in Daily Study Groups. In short, the secret to the success of Wolfram Daily Study Groups comes down to a combination of talented instructors, reliable event management and the power of the Wolfram Language. Running a daily online program is a big task and requires much coordination and teamwork. My thanks go to Cassidy Hinkle, technical project manager for Wolfram U, and all the instructors and teaching assistants who helped make Daily Study Groups a reality.

Check out Wolfram U for a wealth of free interactive courses, video courses and special events.
