Self-directed online learning is becoming increasingly prevalent. We describe a study on the use of an online laboratory for self-directed learning through the construction and simulation of conceptual models of ecological systems. We analyzed the modeling behaviors of 315 learners and 822 instances of learner-generated models using a sequential pattern mining technique. We found three types of learner behaviors: observation, construction, and exploration. We found that while the observation behavior was most common, exploration led to models of higher quality.
Mental illness such as psychosis and schizophrenia are serious public health concerns. However, timely detection of an episode of psychosis is often difficult due to several reasons such as social stigma, lack of mental health awareness and literacy, and the retrospective nature of clinical therapy. We examine the potential of leveraging social media disclosures as a new kind of lens in characterizing and predicting experiences leading up to a psychotic episode.
