The LUPE-Toolbox
The LUPE-Toolbox has been developed and field-tested over several years in a strategic research-practice partnership involving researchers from Trier University and over 20 elementary schools in eight German federal states.
The LUPE-Toolbox is based on the following understanding of potential: Potential is the achievement-related developmental potential of an individual. A student’s potential is not limited to a single ability, but consists of a variety of characteristics (referred to as talent characteristics), including abilities, personality traits, and acquired skills. Potential can be developed and nurtured, and it can differ by domain (e.g., mathematical or scientific potential).

The LUPE-Toolbox is a toolbox for the classroom. It contains modular materials that create a variety of opportunities for students to show their potential. Teachers can use it to observe their students’ talent characteristics in mathematics and natural science education, which helps teachers to identify potential.
The LUPE-Toolbox provides opportunities to observe the following talent characteristics:

To use the LUPE-Toolbox, the following requirements must be met:
- Participation in a LUPE training course
- Familiarization with the manual
- Formation of a LUPE team with at least two members at the school
Contents of the LUPE-Toolbox
Core material
Manual for the users of the LUPE-Toolbox including background information and practical tips
LUPE-Lessons
- Detailed lesson plans, observation sheets, work materials with mostly open-ended tasks, and instructions for evaluating students’ behaviors
- To be conducted with the whole class or with groups
- 1 to 4 related lessons on a topic
LUPE-Interviews
- Guides for short conversations supported by pictures as well as instructions for evaluating students’ answers
- To be conducted with the whole class, groups, or individual students
- 10 to 30 minutes
LUPE-Questionnaires
- Work materials with closed tasks or questions with answer options for the students as well as instructions for evaluating students’ answers
- To be conducted with the whole class, groups, or individual students
- 10 to 30 minutes
Potential-Portfolio
- Collection of individual student’s results, documentation of observations of the student and his or her developments
- Observation plan for the whole class
The materials can be used specifically in mathematics lessons, in natural science lessons or in both subjects (cross-curricular). The following figure shows the assignment of materials to subjects:
