A New Approach to Teaching Programming
Motivation
• For students:
• Biggest Challenge to Student Innovators: They Can’t
Build Their Vision
• Steep and long learning curve
• Existing classes are intimidating (everyone gets it but
me) and it’s hard to build a business in just python.
• For faulty:
• Coding courses require way to much prep & re-prep
• Could we bring students from no coding experience to
confidently build a full-stack app in just one semester?
• Can we make it easier on faculty? A light-lift / high-
impact so they’ll want to teach this?Learn to Program Using Swift
for iOS Development
• Flipped Class - Lectures via video, Exercises in Class
• Traditional Approach vs. Swift for iOS Development
• Student misses something & they’re lost vs. constant review
• Chalk & talk vs. hands-on
• Homework struggles vs. Skill-building challenges and classroom camaraderie
• 1st courses are usually dull, text-based examples w/tired, unreliable standards like
“programming fibonacci sequences” and “find the Prime number”. vs. App coding right

• A Very Light Lifting Programing Course

• Class questions + answers prepped

Showcase, promote on social media)More Motivating than Python, Java, or Visual Basic Traditional Approach: • Many intro courses use text-heavy languages like python • Classic courses rely on tired computer science staples that fail to excite students (e.g. find prime numbers, code Fibonacci sequences) • Students usually aren’t building apps until several courses into their college career (3 at BC, CS1, CS2 come first)

flipped classroom style.”Minimal Prep and Light Lifting for the Instructor Traditional Approach: • Faculty prep multiple lectures, with ever- changing technologies. • Instructors fill much of class time with lecturing, being “on” constantly, and sometimes sidelined by uncooperative tech or unexpected bugs. • New students demand a lot of instructor time when struggling with unfamiliar concepts.
Minimal Prep and Light Lifting for the Instructor
Flipped Approach:
• Professors have no lecture prep. All lectures are delivered
via videos in the online book.
• Online quizzes at the end of each section verify learning,
and point students to reference if they answered incorrectly.
• The text’s animations explain abstract concepts, like loops
and indexing, better than chalk or slides.
• Class time is spent with students solving problems related
to video projects they’ve completed during the week.
• Collaborative work is encouraged, with students learning
from peers and learning more by explaining concepts.
• Slides + Solutions to all exercises are provided to faculty
in advance.
• Students are less demanding of instructor time since they
can review lessons and many exercise solutions online.
