In this interview with Shuchi Grover, we discuss the importance of having a variety of assessments in a CS class, why we need more research on computational thinking, why educators and scholars should read literature outside of the field, Shuchi’s new book titled “Computer Science in K-12: An A-To-Z Handbook on Teaching Programming,” and much more.

Guest Bio
Shuchi Grover is a senior research scientist at Looking Glass Ventures and a visiting scholar at Stanford University. Her research is focused on teaching and learning of computer science, computational thinking, and programming in schools. She has been working with children and programming since 2001, first in informal afterschool settings, and recently, in classrooms. Her current research encompasses the design of curricula and assessments for all levels of preK-12 CS education, as well as the integration of computing and coding in STEM and other subjects. She has led, and continues to lead, several large research projects (often in collaboration with universities and research organizations) with grants from the US National Science Foundation and other federal agencies. She also consults globally on projects related to K-12 CS, programming, and computational thinking education. She edited and co-authored the recently released "A to Z Handbook on Teaching Introductory Programming" for K-12 teachers.

━━━━━━━━━━━━━

Each episode of the #CSK8 Podcast explores research, experiences, or perspectives on computer science education through interviews with computer science educators, scholars, and administrators, as well as episodes that summarize and unpack implications of research for classroom teachers who are interested in learning more about practical applications of research in their classroom.

_________________ABOUT_____________________
Complete K12 essentials Youtube channel and Complete K12 Essentials.com was created to offer parents and teachers an online augmentation or alternative when public schools are not available. The need for standard curriculum that can be delivered via the internet became obvious during the pandemic of 2020. Teachers and school districts were left to create lesson plans and somehow connect with the students with very little time. The challenge was to give each child a method to connect with teachers and class mates to simulate a natural learning environment. Navigating through the material suitable for each grade level is a difficult task at best, so we have created the “SAFE LEARNING PLACE” logo and apply it to all of our videos to show you our dedication to providing good learning material that can be trusted across our whole channel. The curriculum will cover Math, Language Arts, Social Studies, Science, Technology, Music, Art, Health and Fitness, Foreign Languages, Life Skills, Career training, History and Law.

Title: Writing Fractions from Drawings - Fast And Easy Math Learning Videos

In this lesson you’ll learn to write the fraction that’s shown in a picture.
For example suppose you want to write the fraction shown by the shaded part of this picture. In this case the square is the whole.
And the whole is divided into 4 equal parts.
So 4 is our denominator.
3 of the parts are shaded.
So 3 is our numerator.
The shaded part of the picture shows three-fourths.
Let’s look at another example.
In this case the whole is the triangle.
The triangle has been divided into three parts.
However, the parts are not equal in size, so we can’t write a fraction from this picture. To write a fraction, the figure would have to be divided into equal-size parts.
Let’s look at another example.
In this case the whole is a circle.
Notice that we have two wholes shown.
The wholes are each divided into five equal parts.
So the denominator is 5.
7 of the parts are shaded
So the numerator is 7.
The shaded part of the picture shows seven-fifths.
Let’s look at one last example.
In this case the whole is a rectangle.
Notice that there are 4 wholes shown.
Each whole has been divided into three parts
So the denominator is three.
10 of the parts have been shaded in
So the numerator is 10.
The shaded part of the picture shows ten-thirds. In the remainder of this lesson you’ll write the fraction shown by the shaded part of a picture. Now do the rest on your own.

A massive thanks to Prof. Hans-Thomas Janka for helping us with the physics of supernovae and GRBs. A massive thanks to Prof. Brian Thomas for all of his help with the terrestrial effects of supernovae and GRBs. This video would not have been possible without them. Also thanks to Dr. Luke Barnes for his initial help with the literature search.

Hydrogen bomb vs Supernova fact was taken from this great article by xkcd/Randall Munroe – https://what-if.xkcd.com/73/ (based on the calculation by Andrew Karam, 2002)
