# Smart leerdoelen
Na de retrospective die ik heb gedaan, heb ik besloten om de volgende smart leerdoelen te stellen:
1 **Ik wil in de volgende blok meer gaan opletten op mijn teamgenoten om zo goed te weten waar iedereen mee bezig is.**
**specifiek:**
ik heb in onze groep de taak als voorzitter alleen merk ik op dit moment dat ik niet goed weet waar iedereen mee bezig is. Dat is niet handig omdat ik dan als voorzitter niet goed kan inschatten of iedereen op schema ligt.
**meetbaar:**
Ik wil dat ik aan het einde van de blok meer contact heb gehad met mijn teamgenoten en dat ik weet waar iedereen mee bezig is. Dit zorgt ervoor dat ik beter kan inschatten of iedereen op schema ligt en of ik moet ingrijpen.
**acceptabel:**
Dit is acceptabel omdat ik als voorzitter de taak heb om te zorgen dat iedereen op schema ligt en dat iedereen weet wat hij/zij moet doen. Zonder deze informatie kan ik niet goed mijn taak uitvoeren waardoor de teamgenoten niet goed kunnen werken.
**realistisch:**
Dit is realistisch omdat ik als voorzitter de taak heb om te zorgen dat iedereen op schema ligt en dat iedereen weet wat hij/zij moet doen.
**tijdgebonden:**
Ik wil dit doel behalen aan het einde van de blok. Dit is een realistische tijd omdat ik dan genoeg tijd heb om dit doel te behalen. Ik kan mij later ook nog tijdens de opleiding verbeteren op dit punt.
---
2 **Ik wil in de volgende blok meer gaan opletten op mijn eigen documentatie.**
**specifiek:**
In tegen stelling tot vorig jaar hou ik nu mijn documentatie niet goed bij. Dit is niet handig omdat ik dan niet goed kan zien wat ik daadwerkelijk heb gedaan en wat ik allemaal heb geleerd. Ook is het fijn dat ik dan kan terug kijken op mijn werk als ik het later nodig heb. Ik wil daarom minimaal 2 keer per week mijn documentatie bijwerken.
**meetbaar:**
Ik wil dat ik aan het einde van de blok mijn documentatie goed heb bijgehouden. Dit zorgt ervoor dat ik kan zien wat ik heb gedaan en wat ik allemaal heb geleerd. Ook kan ik dan terug kijken op mijn werk als ik het later nodig heb.
**acceptabel:**
Dit is acceptabel omdat ik dan toekomst gericht kan werken. Ik kan dan terug kijken op mijn werk als ik het later nodig heb. Ook kan ik dan zien wat ik heb gedaan en wat ik allemaal heb geleerd.
**realistisch:**
Dit is realistisch omdat ik dit vorig jaar ook heb gedaan. Ik weet hoe ik mijn documentatie moet bijhouden en wat ik allemaal moet opschrijven. Mijn eis van 2 keer per week is ook realistisch omdat ik dan genoeg tijd heb om mijn documentatie bij te werken.
**tijdgebonden:**
Ik wil dit doel behalen aan het einde van de blok. Dit is een realistische tijd omdat ik dan genoeg tijd heb om mijn documentatie bij te werken.

/*
TinyGPSPlus - a small GPS library for Arduino providing universal NMEA parsing
Based on work by and "distanceBetween" and "courseTo" courtesy of Maarten Lamers.
Suggestion to add satellites, courseTo(), and cardinal() by Matt Monson.
Location precision improvements suggested by Wayne Holder.
