Preparing biology paper 1 examinations – cpdIan Chirambo
This document provides guidance on preparing multiple choice questions for a biology examination. It discusses the importance of using the cognitive domain, biology syllabus, and test specification table to guide question development. The six levels of cognition - from knowledge to evaluation - are outlined. Rules for writing effective multiple choice questions are also presented, such as using plausible distractors, emphasizing higher-level thinking, and avoiding clues to the correct answer. The goal is to generate questions that reliably test students' understanding of the biology concepts outlined in the syllabus.
The document provides an overview of the Forensic Science course for 12th graders. The class will apply concepts from biology, chemistry, and physics to topics like evidence collection and DNA analysis. Students will participate in lectures, discussions, group work, labs, and projects. They will need textbooks, notebooks, and will complete regular homework, vocabulary quizzes, lab reports, and a final crime scene project. Guest speakers and field trips will also enhance learning. Grades will be calculated using a points system for tests, quizzes, assignments, and labs. Late work will be accepted with a 10% per day penalty. Extra help is available by appointment.
Gregor Mendel conducted experiments with pea plants to study heredity. He found that traits are passed from parents to offspring through discrete units (now known as genes and alleles). In his F1 hybrid offspring, dominant traits always appeared, but in the F2 generation the "lost" recessive traits reappeared in about 25% of plants. Mendel's work established the foundations of genetics and showed that heredity follows basic rules of dominance and segregation.

A review of phthalates and the associated reproductive and decelopmental toxi...Emma Greenwell
This document summarizes a literature review on the reproductive and developmental toxicity of phthalates towards fish. It discusses common phthalates like DEHP, DBP, DINP and DIDP.

The simplified electron and muon model, Oscillating Spacetime: The Foundation...RitikBhardwaj56
Discover the Simplified Electron and Muon Model: A New Wave-Based Approach to Understanding Particles delves into a groundbreaking theory that presents electrons and muons as rotating soliton waves within oscillating spacetime. Geared towards students, researchers, and science buffs, this book breaks down complex ideas into simple explanations. It covers topics such as electron waves, temporal dynamics, and the implications of this model on particle physics. With clear illustrations and easy-to-follow explanations, readers will gain a new outlook on the universe's fundamental nature.
A Strategic Approach: GenAI in EducationPeter Windle
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.
