KISP - Gantt Chart of Tasks and ActivitiesAve Mejia
The Gantt chart outlines the tasks and activities across 3 phases of the project from February to July. Phase 1 involves initiating communication between teachers and the core team to identify topics, process, and calendar for the project. Phase 2 focuses on implementing national projects and sharing processes and products between countries. Phase 3 has teachers work on a multi-national/inter-cultural group project by identifying topics, implementing the project, and sharing outputs online.
This document discusses object-oriented programming concepts. It defines encapsulation, abstraction, inheritance, and polymorphism as key features of OOP. Encapsulation hides implementation details and abstraction focuses on essential object characteristics. Inheritance creates a class hierarchy for code reuse. Relationship types between classes include kind-of, is-a, part-of, and has-a. Inheritance can be single, from one superclass, or multiple, from more than one. Polymorphism means an entity takes on different meanings in different contexts.
The document discusses object-oriented programming concepts like inheritance, relationships between classes, and implementing inheritance in C++. It aims to help students understand key terms like superclass and subclass, different types of relationships like inheritance and composition, and how to derive a subclass from a base class in C++. The document also provides examples and problem statements for students to practice these OOP concepts.
This 3-week project examines whether humans are more alike or different. Students will independently answer the driving question in their electronic portfolios based on lab activities. Content standards address genetics and inherited traits. Students will break into groups to compare physical traits and create a chart of their similarities and differences. Assessments include quizzes, presentations, journals, and an electronic portfolio. The project provides scaffolding to develop an understanding of concepts through inquiry and hands-on activities.
Students created two-sided identity masks representing their personal identity on one side and a chemical element symbolizing their personality on the other. Over four weeks, they learned about atomic structure, the periodic table, and trends to understand which element best represented them. They gave oral and written presentations explaining their masks to classmates and connecting their cultural identity to an element's properties.

Java is an object-oriented programming language developed by James Gosling at Sun Microsystems in 1991. It derives much of its syntax from C and C++ but is designed to have as few implementation dependencies as possible so that applications written in Java can run on any device with a Java Virtual Machine (JVM). The JVM converts Java bytecode into machine code that can be executed by the device's processor. This allows Java programs to run on any platform that has a JVM without needing to be recompiled.
The document discusses inheritance and interfaces in Java. It explains that inheritance allows a subclass to inherit data members and methods from a superclass. It also describes method overriding, where a subclass overrides a method from the superclass with the same signature. The document also discusses interfaces, which define a common behavior for multiple classes to implement, allowing for multiple inheritance in Java.
The document provides an introduction and history of Java, outlining how it was developed in the 1990s as a platform-independent language by James Gosling at Sun Microsystems, and discusses some key advantages of Java like being object-oriented, portable, robust, and having built-in support for security and multithreading.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
