LANTERN as a learning sensor

Lantern collects information that can be of great value for the teacher:

  • How much time the students spent on each exercise
  • How long they waited for help
  • How much assistance they needed on each exercise
  • If there were teams who did not progress as expected

We offer online visualization tools that let you measure your class performance and spot the the patterns of success and shortcoming.

Exercise Difficulty

For each exercise there is a vertical bar and the y axis represents time. In figure below , each bar indicates how much time on average the teams spent working on the corresponding exercise (in blue), how much help or explanation it required (in red), and how long students had to wait until receive help on that exercise (in yellow). The teacher may interpret that Exercise 2 was particularly complex and the students could not solve it without help, whereas Exercise 4 was straightforward even though it required much time. 

Team Performance 

Each team of students is represented by a vertical bar and the y axis represents time. In Figure below a bar corresponding to each team indicates how long they worked on the exercise set (in blue), how much help they received from the tutors (in red), and how long they waited (in yellow). Any combination of the three indicators can be shown within the same chart. 

Interactive Diagrams

Lantern data can be shown in a more interactive and intuitive way than static bar charts. Figure below represents each lamp by a colored block and arranges the blocks in such a way that it simulates a classroom viewed from above. The colors of the blocks represent the status of teams and the evolution of the lamps is shown through the change of color over time in consecutive frames. The user can interact with the diagram by zooming (to change the interval between snapshots or to change the size of the blocks) and panning (to browse through the different snapshots.)

In another version, we modified the idea so as not to display a view of a classroom but to have one team per row (Figure below). This way, the progress of a team over the session can be tracked on one horizontal line. The states of the teams are represented as colored blocks (progress, waiting, and receiving help).  The brightest blue corresponds to the first and the darkest to the last exercise. The white gaps show the times when a team was taking a break.

Customized Solutions 

Apart from general visualization tools that are designed to serve supervised collaborative problem solving session, we offer customized visualization and data analysis that work the best for your special project.
