The document summarizes a study that examined how perceptions influence the use of learning tools. 58 university students completed tasks using different tool conditions (guideline, video, both or none) and questionnaires on self-efficacy and metacognition. Results showed that the video condition outperformed other conditions, indicating tool functionality. Tool choice did not affect performance. Variables like self-efficacy and metacognition did not significantly predict tool choice perception. The study suggests further research on tool design and familiarity factors that influence learners' tool perceptions.
