Content

Topics: Cognitive bases of digital development in children and dyscalculia - Pre-numerical tools in babies, including the analog line metaphor (or ANS: approximate number system)
- Counting (development of the verbal numerical chain) and enumeration (principles and development of the cardinal value of number words)
- Symbolic codes :
- oral/written verbal numbers, arabic numbers, lexicon, syntax, transcoding
- base 10 representation
- Access to the magnitude of large numbers
- Link between these basic numerical capabilities and arithmetic performance
- Calculation :

1. o Sensitivity to additions-removals in babies; non-verbal calculations in infants, approximate calculation ;
2. o strategy development, Siegler's association distribution model, base 10 for complex calculations

- word problem solving
- Rational numbers: decimal numbers and fractions
- Dyscalculia :

1. o definition, prevalence, difficulties presented, associations with other disorders,
2. o causal hypotheses (genetic contribution; role of general cognitive factors, deficit in basic numerical factors, etc.)
3. o neuro-functional correlates
4. - Rehabilitation and experimental training

- Special issues that may be considered:

1.  relationship between fingers and numbers ;
2. hypersensitivity to interference in arithmetic fact deficits;
3. deficit of the semantic representation of number in visuo-spatial dyspraxias.

Teaching methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

This year, the course will alternate between a few lectures (the first and last) and presentations by teams of students.

Evaluation methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

The certification evaluation is carried out in two parts: on the one hand, the oral presentation of a precise synthesis carried out in a team on one of the topics covered by the course and on the other hand, by a written exam containing mostly open questions requiring a short and precise answer. The exam may also include some multiple choice questions. During the September session, if a very small number of students are registered for the exam, the teacher may decide to propose an oral exam instead of a written exam.
