Système d'écriturevignette|400px|Carte légendée des systèmes d'écriture dans le monde. Un système d’écriture est un ensemble organisé et plus ou moins standardisé de signes d'écriture permettant la communication des idées. En général, il s'agit de la transcription de la parole énoncée dans une langue parlée : on parle alors de glottographie. Il existe cependant des systèmes transmettant des idées sans l'intermédiaire direct de la parole : on parle alors de sémasiographie, que tous les spécialistes ne s'accordent cependant pas à considérer comme de véritables systèmes d'écriture ; on parle donc également de pré-écriture ou de proto-écriture.

Expérience de terrainUne expérience de terrain est une expérience scientifique qui a lieu dans le monde réel plutôt que dans un laboratoire. Ce protocole est souvent utilisé en économétrie appliquée pour évaluer l'effet causal d'une politique publique. Le Projet STAR (Student-Teacher Achievement Ratio) est une expérience de terrain menée dans l'État du Tennessee à partir de 1985 pour évaluer l'effet de la taille des classes sur les résultats scolaires des élèves.
Video lessonA video lesson or lecture is a video which presents educational material for a topic which is to be learned. The format may vary. It might be a video of a teacher speaking to the camera, photographs and text about the topic or some mixture of these. The Khan Academy has been successful in teaching mathematics using notes written using Yahoo!'s doodle pad with a voiceover by Salman Khan (educator). These were then loaded onto YouTube where they have been popular and influential.
TutoringTutoring is private academic support, usually provided by an expert teacher; someone with deep knowledge or defined expertise in a particular subject or set of subjects. A tutor, formally also called an academic tutor, is a person who provides assistance or tutelage to one or more people on certain subject areas or skills.

Tutoring can take place in different settings.
OrchestrationOrchestration is the study or practice of writing music for an orchestra (or, more loosely, for any musical ensemble, such as a concert band) or of adapting music composed for another medium for an orchestra. Also called "instrumentation", orchestration is the assignment of different instruments to play the different parts (e.g., melody, bassline, etc.) of a musical work. For example, a work for solo piano could be adapted and orchestrated so that an orchestra could perform the piece, or a concert band piece could be orchestrated for a symphony orchestra.

Contre-réactionvignette|Modèle simple de contre-réaction. En électronique le principe de la contre-réaction permet le contrôle des circuits d', de filtrage ou d'asservissement. Elle permet de rendre leurs caractéristiques de fonctionnement indépendantes, dans une large mesure, des différents constituants internes de ces systèmes. Le principe de la contre-réaction a été découvert par Harold Stephen Black le 2 août 1927. Cette idée lui serait venue alors qu'il se rendait à son travail aux laboratoires Bell.
