The document discusses the discriminant of a quadratic equation ax^2 + bx + c = 0, which is the value b^2 - 4ac. The sign of the discriminant (whether it is zero, positive and a perfect square, positive but not a perfect square, or negative) determines the nature of the roots of the quadratic equation. Examples of quadratic equations with different discriminants are provided.

introdution-to-html.ppt
HTML is a markup language used to create web pages. It uses tags to describe and format the structure and content of a web page. An HTML document has two main parts - the HEAD and the BODY. The HEAD contains metadata like the title and is not visible. The BODY contains all the visible content, including text, images, and other media. To create a basic HTML document, it needs tags for the HTML, HEAD, and BODY elements.

This document discusses trigonometric ratios of special angles, specifically the 45-45-90 right triangle theorem. It defines a 45-45-90 triangle as an isosceles right triangle where the two legs are equal to each other and the non-right angles are both 45 degrees. The 45-45-90 triangle theorem states that in this type of triangle, the legs are congruent and the length of the hypotenuse is twice the length of one leg. There are examples of applying this theorem to find missing side lengths. The document ends with a quiz and an assignment problem involving a 45-45-90 triangle.

South African Journal of Science: Writing with integrity workshop (2024)Academy of Science of South Africa
A workshop hosted by the South African Journal of Science aimed at postgraduate students and early career researchers with little or no experience in writing and publishing journal articles.A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Assessment and Planning in Educational technology.pptx
In an education system, it is understood that assessment is only for the students, but on the other hand, the Assessment of teachers is also an important aspect of the education system that ensures teachers are providing high-quality instruction to students. The assessment process can be used to provide feedback and support for professional development, to inform decisions about teacher retention or promotion, or to evaluate teacher effectiveness for accountability purposes.

- 1. The Nature of the Roots of a Quadratic Equation
- 2. The value of the expression b2 – 4ac is called the discriminant of the quadratic equation ax2 + bx + c = 0.
- 3. This value can be used to describe the nature of the roots of a quadratic equation. It can be zero, positive and a perfect square,
- 4. positive but not perfect square, or negative. Example: 1.x2 -4x + 4 = 0 3. x2 + 6x + 3 = 0 2.x2 + 7x + 10 = 0 4. x2 + 2x + 5 = 0
