A tool randomly forms the home and expert groups for the Jigsaw technique
“Rompecabezas – Técnica Jigsaw” takes a list of students and subtopics and splits them into balanced groups. It opens in the browser and is available in five languages.
“Rompecabezas – Técnica Jigsaw” is a tool for organising jigsaw cooperative learning in the classroom. In this technique, each student becomes an expert in one part of the topic, then shares it with their group, and everyone needs the others to complete the whole. The app takes care of the heaviest part for teachers: forming the groups.
The start screen has two panels. On the left, you type the students’ names, one per line, or click “Cargar ejemplo” to try the tool with sample data. On the right, you choose the number of subtopics, which matches the number of members in each home group, give each one a name (the screenshot shows four, each in a different colour) and, if you wish, enter the general topic, for example “El aparato digestivo”. When you click “Formar grupos”, the tool assigns students at random, with the subtopics spread evenly.
According to the listing, when the number of students does not divide exactly, the extras are handled as co-experts. The listing adds that the app guides the three phases of the technique (home groups, expert groups and return to the home group) with prompts, a timer and a printable view. Once the groups are formed, the app also shows steps numbered 1 to 3 and a ten-minute timer with start and stop buttons.
The listing classifies it as a creation tool for Primary, Secondary, Upper Secondary, Vocational Training, University and Teacher Training, and for any subject, since it helps organise the class and does not depend on any particular content. The interface can be switched between Spanish, Catalan, Galician, Basque and English. It is used directly in the browser, and the start screen does not ask for an account.
