Schoolhouse MUN 2024 - UNDP Committee

    Ended Sun, Jan 14, 2024
Hey everyone! We’re excited to welcome you to the committee sessions for the (committee name) committee of the Schoolhouse Model United Nations 2024!

Schoolhouse MUN is an online Model United Nations event organised by a team of schoolhouse.world volunteers in which delegates will get the chance to represent different countries in 6 different committees of the United Nations to gain exposure to how the UN works, enhancing their knowledge on current world issues and improving their public speaking, collaboration and leadership skills.

The UNDP committee will be chaired by Kirill and Alexander.
The agenda for our committee is: accelerating the creation of inclusive and sustainable industrial development.

If you haven’t already, register for the main event’s series here: https://schoolhouse.world/series/12576

Please note that you need to join at least three committee sessions to receive a certificate of participation.

If you’re unsure of your committee allocation, please take a look at the event coda doc.

If you’d like to join as an audience member, we’d love to have you there!

We look forward to seeing you at the committee sessions!

Schoolhouse Model United Nations 2024

    Ended Sun, Jan 14, 2024
Hey everyone! We are really excited to welcome you all to the second edition of the Schoolhouse Model United Nations!

What is an MUN and Why Should You Participate?
For those who may not be familiar with MUN, it stands for Model United Nations, which is a simulation of the United Nations, with delegates taking on the role of a country’s representative to discuss and find solutions to pressing global issues. MUNs are a great opportunity to develop your public speaking, negotiation and problem-solving skills. And we’re excited to host the second edition of Schoolhouse MUN to give y’all these opportunities on the Schoolhouse.world platform!

About the Event:
The event will consist of opening and closing ceremonies, with training sessions for all delegates. There are six committees, with the details for each as follows:

United Nations Development Programme: Accelerating the creation of inclusive and sustainable industrial development
United Nations General Assembly: Discussing causes and solutions to animal extinction
United Nations Environment Programme: Analysing the progress of the Paris Climate Agreement
United Nations Educational, Scientific and Cultural Organisation: Discussing the viability of a Common Universal Education System
United Nations Women: Economic and political empowerment of women
Food and Agricultural Organisation: Assessing the causes and consequences of unequal food distribution across landmasses and regions

The event will take place from 13th to 14th January, 2024 (Eastern Hemisphere time), with 3 committee sessions taking place everyday, each for one hour. Each delegate who attends at least half of the committee sessions will receive a participation certificate, and winners will receive certificates of excellence. The best delegates from each committee will also win Schoolhouse merchandise!

How to Participate:

1. Register for this series to be a part of the opening and closing ceremonies, as well as the training sessions for all delegates.
3. Your committee and portfolio will be assigned to you, and study materials for the same will be shared. After that, you’ll have to register for your committee’s series. The link for the same will be shared with you.
4. Read the rules of procedure and the study material thoroughly, and research further on your committee’s agenda and your country’s stance regarding it to prepare for the conference.
5. Take part in the conference!

For further details about the event, please take a look at the official event coda doc: https://coda.io/@hafsahm/schoolhouse-model-united-nations-2024


If you have any questions, feel free to ask them in the series public discussion below or reach out to [email protected], and we’d be happy to answer!

Note: If you’d like to join the event as an audience member, you are more than welcome to do so!

We hope you will join us for this exciting and enriching opportunity to learn about global issues and hone your public speaking and negotiation skills. We look forward to seeing you there!

Elementary Linear Algebra

    Ended Wed, Feb 14, 2024
(Reboot of my last series) Hi, everyone! I'm proud to present Schoolhouse's first series on Linear Algebra! In this class we will cover all the standard topics of a first class in Linear Algebra (typically take sometime after Calc 2 for greater mathematical maturity, though it can be taken after Calc 3 or before Calculus in the first place.) To be clear, here are the pre-requisites: Algebra (1 and 2, and including Trig) are mandatory. Calculus 1 and 2 are strongly recommended just for maturity, but not required (if you get straight A's in all of Algebra 2 and Trig you should mostly be fine); Calc 3 helps as well (and when I set up my Calc 3 series we will be employing Linear Algebra so if that interests you this course is recommended.) I've taken Multivariable Calculus with Linear Algebra (applied) as well as Linear Algebra itself (proof-based) at Stanford OHS and Stanford ULO, getting an average of B+ on both, and am currently finishing Real Analysis. Generally, here are the topics we will cover (each week): 1. Basic vector operations in R^n 2. Vector Spaces and Subspaces induction technique. 3. Linear independence and Gram-Schmidt 4. Projections and Fourier's Formula 5. Linear Transformations, Properties, and Kernel 6. Matrix operations, special matrices, and matrix properties. 7. Determinants, Linear Systems, Inverse Matrices, and LU decomposition 8. Row, Column, and Null Space, Rank and Nullity 9. Change of Basis, Eigeneverything, and Diagonalizability 10. TBD: QR Decomposition and more on Transpose, Orthogonal Complements, Markov Chains, or anything else. The course expectation is at least 5 hours per week apart from class, office hours, and quizzes. (About 3 hours reading and 2 hours doing homework.) We will meet every Thursday and Saturday at the same time. In class we will not cover all the content (there is simply not enough time), rather we will discuss and go over the proofs the main results, which also appear in the text. We will skip over proofs and results whose proofs we all understand. We will focus on examples and practice in preparation for the assigned exercises and quizzes. We will use Bronson's "Linear Algebra - Algorithms, Applications, and Techniques" as our main text, (http://ndl.ethernet.edu.et/bitstream/123456789/24629/1/Richard%20Bronson.pdf ) in addition to Stanford's Math 51 text (fragments taken under fair use law which will be posted gradually).

Pre-Algebra to Algebra 1

    Ended Mon, Apr 4, 2022
Hey guys! After receiving a considerable number of requests to host an Algebra series after my recent Geometry w/Trig, I decided to do it! :) Once again, we're going to start from the very beginning of Algebra up to Algebra 1. By the end of the series you will be familiar with... - Single/Multi-varied equations and how to solve them - Rates, Percentages, and Ratios (as well as basic rational equations and how to solve them) -Linear Functions/systems of equations w/Inequalities -Functions (domain, codomain, range, inverse, composite, transformations) -Absolute and pice-wise equations - Exponentials (properties of and functions) -Factoring basic polynomials/quadratics -Forms of quadratics/solving quadratic equations -Complex Numbers -Sequences (arithmetic and geometric). Each session is an hour to an hour and a half. We will have sessions each Monday and Wedsnday. At the end of each session we will test our knowledge with a Quizz. All of my sessions have slides that I share with learners, along with quizlets and relate resources. Homework is optional but recommended and we go over it at the beginning of each session briefly. All of the resources (slides, homeworks, etc. is organized on a google sites which I share with everyone). You can always join even after the series has begun, I'm always open to hosting catch-up sessions :) YOU CAN JOIN THE SERIES AFTER IT'S BEGUN! This is going to be a lot of fun, are you ready?

Systems of equations

**This session was made specifically for Alysia** (2 hours) Today we will cover what systems of equations are, how they are represented graphically, analyzing the three possible cases (no solutions, one solution, infinite solutions). Then, we will practice with word problems on Khan Academy and potentially attempt the corresponding unit tests.
