I never uploaded Part 3! Apologies. Part three is about mind mapping - the advatages to it and how to do it. The grade 9's seemed much more comfortable with this, as opposed to part one and two, which indicates that that is clearly their weakness.
Grade 9 CAPS-aligned. The grade 9's are expected to know the symbology involved in chemsitry. This is the introduction of formulae, symbols and atoms and molecules and elements and compounds. This is also a handy tool for grade 8 chemistry.
Grade 10 eletrostatics unit, CAPS- aligned. The unit includes calculation of charge on two isolated spheres, and quantisation of charge. Text taken/adapted form Andries Olivier's Textbook and Workbook.
Grade 10 CAPS-aligned unit on magnetism, from magnetic domains to visual representation of magnetic fields. Includes the magnetosphere and aurora phenomenon.
Part 2 of a multi-part lesson. Part 2 covers the narrow techniques required to memorise lists and sequences. This lesson turned out log - we spent two hours on it.
This is part one of a multi-part lesson. I chunked it, because each individual skill is so important. The textbook barely does this section justice, so my principal gave me licence to extend it and do the work as detailed as I can afford, taking time constraints into consideration.
Part 1 focuses on reading to extract knowledge from a text,
Life long learning and planing (lesson 2)Lily Kotze
I have to teach Life Orientation this year, ensuring I cover the syllabus as well as some study methods.
This lesson was focused on what life-long learning is and it's importance. I also included Planning for studies, as the time for all of this is not enough and we have to double-up on lessons sometimes.
The grade 9's do a basic introduction to the systems in the human body. This slide focuses on the respiratory system. The text is derived from the DocScientia series, which is CAPS-aligned.
Focus on the atmosphere of the earth, its layers and composition as well as its functions. Grade 9 CAPS - aligned, text taken from the DocScientia series.
A quick overview regarding redox reactions for grade 10's. There are no ionic equations here, and no oxidation numbers yet. This will be re-uploaded as soon as the chapter is completed.
A CAPS-based slide show on the Earth and Beyond Module for grade 9's.
The focus is on recapping the different spheres of the earth, looking at the Lithosphere, and discussing the rock cycle, ores and minerals.
Text comes from the DocScientia Workbooks for grade 9's.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
