The term 'inference' refers to the process of using observation and background knowledge to determine a conclusion that makes sense. Inference is a foundational skill which is a prerequisite for higher-order thinking and different learning skills. Inferences are what we figure out based on an experience. Helping students understand when information is implied or not directly stated, will improve their skill in drawing conclusions and making inferences. Inferential thinking is a complex skill that develops over time and with experience.
