Memorandum

Opdrag:

Kirstenbosch Botaniese Tuin in Kaapstad

  • blindes kan die blare in die kruietuin tussen hulle vingers vryf om dit te ruik en die tekstuur te voel
  • daar is ‘n reling vir hulle om aan vas te hou terwyl hulle stap
  • langs elke plant is ‘n nota in Braille-skrif, sodat hulle kan lees watter plant dit is.

Die storie van Louis Braille

Baie jare gelede het ‘n seuntjie met die naam van Louis in Frankryk saam met sy ouers gewoon. Hy was baie nuuskierig en geïnteresseerd in alles wat rondom hom gebeur. Sy pa was ‘n saalmaker van beroep en hy het vir ander mense saals vir hulle perde gemaak.

Eendag het Louis sonder toestemming in sy pa se werkswinkel ‘n stuk leer met sy pa se skerp mes probeer sny. Hy het nog nooit vantevore met die mes gewerk nie, die mes het geglip en een van sy oë raakgesny. Binne drie dae was daar infeksie in altwee oë en gou daarna was hy blind in beide oë.

Louis was steeds baie geïnteresseerd in alles wat rondom hom aangaan, maar hy het agtergekom dat dit baie moeilik was om blind te wees. Hy moes na ‘n spesiale skool vir blindes gaan waar hy dit baie moeilik gevind het om met hulle metodes te lees. Die letters was so half uitgeswel op die bladsy en hierdie metode was ‘n baie stadige manier van lees, en nog moeilik ook daarby.

Louis was vasberade om ‘n makliker manier te vind om te lees. Eendag het ‘n weermagoffisier vir hulle by die skool kom toespreek oor metodes wat hulle volg om boodskappe in die nag te stuur. Louis het toe die idee gekry om ‘n alfabet met 6 verhewe kolletjies te vorm. Hierdie skrif word Braille-skrif genoem wat ‘n kode van kolletjies op papier is. Jy lees deur jou vingers oor die kolletjies te beweeg.

Louis het later ‘n onderwyser aan die skool geword en het al die blinde leerders geleer om Braille te lees. Hierdie metode was ‘n geweldige vooruitgang in die tegnologie, want vandag kan blinde mense baie meer lees as voorheen, dus kan hulle net soos gewone kinders leer.

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.
