Teacher reports - Mastery Progress & Activity Overview (Hindi)

jeu, 2020-05-28 15:01
Let's see how can we check mastery progress and activity overview for our students on Khan Academy.

How to manage your class and roster (Hindi)

jeu, 2020-05-28 15:01
In this video, we discuss about how teachers can manage their class on Khan Academy. We also talk about how can they add students from one class to another, stop coaching students, and change their passwords.

Student experience on Khan Academy (Hindi)

jeu, 2020-05-28 15:01
In this video, Anmol talks about Khan Academy from a student's point of view. How would students see the content assigned by the teachers? How can they start solving the assignments? We will be discussing all these questions in this video.

Creating a teacher account on Khan Academy (Hindi)

jeu, 2020-05-28 15:01
Let's see how you can create your teacher account on Khan Academy and use it to create class, assign content, and check the performance of your students.

Teacher reports - assignment reports (Hindi)

jeu, 2020-05-28 15:01
Let's see how a teacher can see reports and student's performance on Khan Academy after assigning homework to their students.

Introduction to Khan Academy and Khan for Educators course (Hindi)

jeu, 2020-05-28 15:01
Listen to Khan Academy school implementation team - Vipul Redey, Mathu Shalini, Veenus Katyal about Khan Academy, what makes Khan Academy special and why is this course important.

How to assign mastery goal to your students (Hindi)

jeu, 2020-05-28 15:01
Let's see how can we assign a mastery goal to our students. Assigning mastery goal is similar to assigning an entire class book. Students can do that at their own pace and time.

Our content and course structure (Hindi)

jeu, 2020-05-28 15:01
In this video, we will talk about Khan Academy's content and course structure. We will also see what makes Khan Academy videos and exercises unique.

How to assign content to your students (Hindi)

jeu, 2020-05-28 15:01
Let's see how teachers can assign videos, exercises, and articles on Khan Academy as homework to their students directly from their Teacher dashboard.

Pedagogy at Khan Academy (Hindi)

jeu, 2020-05-28 15:01
Learn about the Khan Academy pedagogy principles - personalized, mastery-based learning that transforms students' mindsets.

How to create and manage student account? (Hindi)

jeu, 2020-05-28 15:01
Let's learn how we can create a Khan Academy account for our students, add them to the class created by us on Khan Academy, and manage the settings for their accounts.

Worked example: Using the ideal gas law to calculate number of moles

mar, 2020-05-19 23:52
The ideal gas law relates four macroscopic properties of ideal gases (pressure, volume, number of moles, and temperature). If we know the values of three of these properties, we can use the ideal gas law to solve for the fourth. In this video, we'll use the ideal gas law to solve for the number of moles (and ultimately molecules) in a sample of gas.

Worked example: Using the ideal gas law to calculate a change in volume

mar, 2020-05-19 23:52
The ideal gas law can be used to describe a change in state for an ideal gas. In this video, we'll apply the ideal gas law to the initial and final states of a gas to see how changes in temperature and pressure affect the volume of the gas.

Representing solids, liquids, and gases using particulate models

ven, 2020-05-08 18:27
In this video, we'll learn how to represent solids, liquids, and gases using particulate models. The particles in a solid are either highly ordered (if the solid is crystalline) or have no regular arrangement (if the solid is amorphous). In both cases, the motion of the particles is limited. The particles in a liquid are close together and are constantly moving and colliding. Finally, the particles in a gas are generally well-separated and are in constant, random motion.

Crystalline and amorphous polymers

ven, 2020-05-08 18:27
Polymers can exist as both crystalline and amorphous solids. In fact, most polymers are semicrystalline, which means that they contain a mixture of crystalline and amorphous regions. In this video, we'll see different examples of semicrystalline and amorphous polymers and learn how their structures can be represented using particulate models.

Creating objective summaries | Reading

mer, 2020-05-06 19:14
All we want are the facts! Today, let's talk about what it means to be objective (and how difficult that is!). When you're summarizing a text, leave your opinions out—save them for analysis! When you summarize a text, do your best to leave judgment behind.

Covalent network solids

mar, 2020-05-05 20:26
Covalent network solids are composed of atoms covalently bonded together into a three-dimensional network or layers of two-dimensional networks. Due to the strength of the covalent bonds, covalent network solids tend to have high melting points. Three-dimensional network solids (such as diamond or silica) are typically hard and rigid, whereas two-dimensional network solids (such as graphite) are much softer due to the ease with which the network layers can slide past each other.

Molecular solids

mar, 2020-05-05 20:26
Molecular solids are composed of discrete molecules held together by intermolecular forces. Because these interactions are relatively weak, molecular solids tend to be soft and have low to moderate melting points. Molecular solids are also poor conductors of electricity because their valence electrons are tightly held within each individual molecule.

Metallic solids

mar, 2020-05-05 20:26
Metallic solids are composed of metal cations held together by a delocalized "sea" of valence electrons. Because their electrons are mobile, metallic solids are good conductors of heat and electricity. Metallic solids also tend to be malleable and ductile due to the ability of the metal nuclei to move past each other without disrupting the bonding.

Ionic solids

mar, 2020-05-05 20:26
Ionic solids are composed of cations and anions held together by electrostatic forces. Due to the strength of these interactions, ionic solids tend to be hard, brittle and have high melting points. Ionic solids are poor conductors of electricity except when their ions are mobile, such as when a solid is melted or dissolved in solution.
