Thinking about learning objectives as a process of modeling

1 - Modeling begins before you ever touch a computer

• How do I understand the system of interest?
• Within that system, what phenomena am I interested in?
• What entities do I think are relevant for my model?
• How might I qualitatively describe entity relationships in the model? (Example: predators hunt prey, so predators should have some contribution to the reduction of prey.)
• What simplifications do I know I’m making?
• How can I express expectations of/predictions about the model? (E.g., with one wolf and 10 million rabbits, I don’t think there will be much of a predator effect. Or: here’s a sketch of the path I think this orbiting body might take. Or: based on my experiences with kerbal space program, I figure the object would take a path like this.)

# prunes tracking branches not on the remote.
git remote prune origin 

# lists branches that have been merged into the current branch.
git branch --merged 

# deletes branches listed on standard input.
xargs git branch -d

// Assuming the delta is entirely insert operations,
// this example wouuld convert bolded text to html bolded text.
// The key logic here is mapping over the insert ops,
// then joining the resulting array on the empty string
html = delta.slice(0, 500).ops.map(function(op) {
   if (typeof op.insert !== 'string') return '';
   let html = op.insert;
