Kritieke- en ontwikkelings uitkomste

Die leerders moet uiteindelik kan:

1. probleme identifiseer en oplos, en ook besluite neem deur kritiese en kreatiewe denke;

3. hulself en hul aktiwiteite verantwoordelik en doeltreffend bestuur;

4. inligting versamel, ontleed, organiseer en krities evalueer;

5. doeltreffend kommunikeer deur middel van visuele, simboliese en/of taalvaardighede in verskillende vorme;

6. wetenskap en tegnologie doeltreffend en krities gebruik deur verantwoordelikheid teenoor die omgewing en die gesondheid van ander te toon;

7. begryp dat die wêreld ‘n stel verwante stelsels is waarin probleme nie in isolasie opgelos word nie;

8. na te dink oor en ondersoek te doen na ‘n verskeidenheid strategieë om doeltreffender te leer;

9. as verantwoordelike burgers aan die lewe van die plaaslike, nasionale en wêreldgemeenskap deel te neem;

10. in verskeie sosiale kontekste kultureel en esteties sensitief te wees;

11. opvoedings- en beroepsmoontlikhede ondersoek; en

12. entrepreneursgeleenthede te ontwikkel.

Integrasie van Temas:

  • ‘n Gesonde Omgewing: Ons paaie word deur baie voertuie gebruik en dit is ‘n belangrike oorsaak van besoedeling. Bespreek. Veiligheid op ons paaie is essensieel. Leerders moet padreëls en veiligheidsreëls wat deur die skool en die owerhede ingestel is, gehoorsaam. Bespreek wat gedoen kan word om die leerders se veiligheid na en van die skool te verseker. Plante en blomme versier ons omgewing en moet beskerm word. Moenie hulle vernietig nie.
  • Inklusiwiteit: Mens, dier en plant is van mekaar afhanklik om te oorleef. Bespreek en gee voorbeelde.
  • Voertuie maak ‘n belangrike deel van leerders se ervarings uit. Aktiwiteite soos tel tot by 150, ‘n grafiek wat afstande en voertuie bepaal, asook die uitbreiding van samestellings van 16, word gebruik.
  • Voorwerpe tot 50 word geskat, gegroepeer en getel.
  • Die vermenigvuldigingstafel van 2 word bekend gestel en optelling en aftrekking van 6, 7, 8 en 9 word ingesluit.
  • Vorms word geïdentifiseer en gesorteer deur hulle in te kleur.

Assessering

Leeruitkomste 1: Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.

Assesseringstandaard 1.9: Dit is duidelik wanneer die leerder hoofberekeninge uitvoer;

1.9.1 optelling en aftrekking van getalle tot minstens 20;

Leeruitkomste 5: Die leerder is in staat om data te versamel, op te som, voor te stel en krities te ontleed om gevolgtrekkings en voorspellings te maak en om toevallige variasie te interpreteer en te bepaal.

Assesseringstandaard 5.4: Dit is duidelik wanneer die leerder teken prente en stel prentdiagramme (piktogramme) saam met ’n 1-1-ooreenstemming tussen eie data en voorstellings;

Assesseringstandaard 5.5: Dit is duidelik wanneer die leerder eie versameling voorwerpe of dié van ’n maat beskryf, verduidelik hoe dit gesorteer is en beantwoord vrae daaroor.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
