This document outlines a marking scheme for grading student investigations in geography. Students will be awarded grades based on their investigation skills and use of detailed, colorful PowerPoint slides. The levels progress from asking simple questions to identifying relevant questions and establishing investigation sequences. Data collection starts with indoor/outdoor observation and progresses to selecting diverse sources and complex data types. Analysis moves from finding answers to presenting conclusions consistent with evidence to justifying valid explanations. The highest levels involve growing independence and analyzing evidence to construct substantiated conclusions.
