Welcome to Computational Thinking for K-12 Educators: Nested If Statements and Compound Conditionals. This course is for educators who not only may want to learn about nested if statements and compound conditionals, but also want to learn to teach it to others, specifically students. In this class, we'll be engaging you with learning not only nested if statements and compound conditionals with better pedagogies, than maybe the ones that you either learn about it before or that we traditionally use with students. Which is just like, "Hey, let me introduce you to a concept, Now go write a program with it." In this particular class, we're going to have an extra focus on debugging. Not only will I share, again my debugging expertise with you about these particular concepts, that we're going to see later our pedagogy focus this course is also about debugging and how to really help our students develop debugging skills. Finally, you'll be experimenting with and also learning yourself how to help your students deepen their analysis skills and their understanding through classroom discussions, around code that engages with nested if statements and compound conditionals. Let me tell you, that's going to be a specially important of course because these two concepts and especially compound conditionals, are where students can really start to get into some challenging difficulties. So, they really need to discuss and argue out in order to figure it out. We'll be starting with an unplugged activity for nested if statements, where we realize that there are some places in our lives where there's just a set of independent conditions where something might be. Students really understand this with grade assignments. You either get an A, a B, a C, a D or an F. There's no other option. But we'll look at these in a variety of places in our life. As usual, we'll be using snap for the majority of our learning of the concepts in this course. But excitingly in this course, we're going to be using an old new free online resource that you can engage students in both block based programming, but also in transitioning from block based programming to typed programming, and that's pencil-code.net. In particular, we'll be looking at some of the default options in pencil-code.net and we'll explore translating a three separate if statements into a nested if statement. Additionally, we're going to be working with compound conditionals. Again, this is, and is always a really challenging thing. It's a logic thing with and's and or's and it's easy to confuse yourself multiple times. We're going be looking at a soccer game and implementing a potential soccer game, and keeping score and keep finding out when things go out of bounds both in our unplugged activity and then we're going to come back to it in our teacher power-up activity. But games are really great place to have students really experience compound conditionals in really relevant and realistic ways. Again, as I said our pedagogy section in this course is about debugging, and debugging is a very challenging skill and we're going to lay out some very specific things that you can engage students and doing to help build up their debugging skills. Finally, for our equity section, there's a very popular activity every year around the world called the Hour of Code. This is a great way to try to promote your course not only just worth for your own students, but particularly about promoting your course and computer science is something that all students should be able to do with both your colleagues, your principal, your administrators and other students in your school. So we'll give you the opportunity to go and explore on the Hour of Code website and see what kinds of things you might want to do in your area with Hour of Code. Finally, as always, our goal in this class is that you never do any busy work. That everything that you do, is something that you can immediately turn around and use in your class or help you to develop your class. Through our peer review activities, that you have the opportunity to share ideas and materials with other people and benefit from that. So, thank you so much for joining us in our class on nested ifs and compound conditionals. I hope you enjoyed.
