The document discusses the establishment of the Croatian e-portfolio chapter in September 2013. It aims to synthesize e-portfolio work in Croatia and neighboring countries and create an online community. The chapter has promoted e-portfolios' educational and career benefits through workshops and presentations. It has also established the Croatian e-portfolio network and shares resources online. The University of Zagreb's e-learning strategy now includes e-portfolios. Its e-portfolio system, run through the E-learning Centre, has over 9,400 users generating over 22,700 pages.
The Europortfolio team presented on July 2 2014 the "ePortfolios and Open Badges Maturity Matrix". The objective was to collect feedback from practitioners and experts on a document that is aimed at helping organisations to plan and reflect on current developments and lay the foundations for the development of a review tool (self-assessment) that will be used to plan, monitor and review ePortfolios and Open Badges policies, technologies and practices.
What was presented is an alpha version (draft) of the Matrix and we are looking forward to the feedback of the community to produce a beta version that will be used to build the self-assessment tool. Based on the outcomes of the self-assessment tool's exploitation, a final version of the Matrix will be produced.

The chemistry of hair dye presentationbridgettefly
ย
This document summarizes different types of hair dyes:
- Temporary hair dyes coat the hair and are easily removed, containing small amounts of peroxide that allow the natural color to return.
- Semi-permanent dyes penetrate the hair shaft more and will fade more slowly.
- Permanent dyes use hydrogen peroxide to remove pigments followed by chemicals that soak into the hair shaft to impart a new color, using ammonia to open the hair cuticle. Overuse or certain dyes can increase cancer risk or damage hair.

Researching ePortfolios: The current state of play led by Darren Cambridge, Babara Cambridge and Kathleen Blake Yancey
This webinar was held on Friday 7th Febuary 2014 by www.europortfolio.org
This webinar discusses the research on e-portfolios, presenting the work of the Inter/National Coalition for Electronic Portfolio Research as a model for collaborative inquiry embedded within the process of implementation that both generates new knowledge and leads to successful results.
Over more than a decade, the Coalition has worked with nearly 70 further and higher education institutions in the US, Canada, the UK, Australia, and the Netherlands to better understand how e-portfolios can supporting learning, assessment, and institutional change.
The webinar will provide an overview of the Coalition's process, survey some results from cohorts that have completed their work, and discuss current questions it is investigating and how they might apply to cross-sector practice in Europe.
For more information about the Coalition and its work see http://ncepr.org/
Webinar leaders will be: Barbara Cambridge, Director, Washington Office, National Council of Teachers of English, Darren Cambridge, Principal Consultant, Networked Learning Group, American Institutes for Research and Kathi Yancey, Kellogg W. Hunt Professor of English and Distinguished Research Professor, Florida State University.

2. Inhoud
1) Enkele opgaven week 3
2) Hoofdstuk 4: Cirkels
i. 4.4: Raaklijnen uit een punt buiten de cirkel (opgave 4.11)
ii. 4.5: Pool en poollijn (opgave 4.12 t/m 4.14)
iii. 4.6: De macht van een punt ten opzichte van een cirkel (opgave 4.15 t/m 4.20)
iv. 4.7: Gemengde opgaven (opgave 4.23 en 4.24)
3. Opgaven week 3
Opgave 4.2 (hint)
Twee mogelijkheden:
(i) Drie punten invullen in vergelijking van cirkel, dan ontstaan er drie
vergelijkingen voor de drie onbekenden ๐, ๐ en ๐.
(ii) Of middelpunt uitrekenen met behulp van de stelling: Middelloodlijnen van
een driehoek van koorden snijden elkaar in het middelpunt van de cirkel.
Opgave 4.3 (hint; een goede schets is hier wel handig)
Nuttige stelling: middelpunt van ingeschreven cirkel is snijpunt van de deellijnen.
Bepaal het middelpunt van de cirkel als snijpunt van twee deellijnen (ieder
tweetal kan hiervoor gekozen worden).
De straal volgt vervolgens als afstand van middelpunt tot een zijde (iedere zijde
kan gekozen worden). Gebruik hiervoor bv. de formule uit paragraaf 2.6.
4. Opgaven week 3
Opgave 4.5c) (hint)
Dit kan formeel door de vergelijking van de lijn in de vergelijking van de cirkel in
te vullen. Dan ontstaat er een kwadratische vergelijking waarvan het aantal
nulpunten met behulp van de discriminant is te bepalen.
Opgave 4.8
Zie dia 8 van week 3.
Opgave 4.10
โEerlijk delenโ toepassen (zie evt. dia 9 van week 3).
5. Raaklijnen uit een punt buiten de cirkel
Uitgangspunt
Een cirkel ๐ถ: ๐ฅ โ ๐ 2
+ ๐ฆ โ ๐ 2
= ๐2
en een punt ๐(๐ฅ0, ๐ฆ0).
Doel
Bepaal de raaklijnen aan ๐ถ door het punt ๐.
Strategie
i. Vergelijking raaklijn: ๐ฆ = ๐ ๐ฅ โ ๐ฅ0 + ๐ฆ0 (๐ onbekend).
ii. Substitueer deze vergelijking in vergelijking van cirkel en er ontstaat een
kwadratische vergelijking in ๐ฅ.
iii. Stel discriminant van deze kwadratische vergelijking gelijk aan nul en los
hieruit ๐ op.
Alternatieve strategie
Los ๐ op uit
|๐๐โ๐โ๐๐ฅ0+๐ฆ0|
๐2+1
= ๐. (waarom is dit correct?)
6. Een raaklijn in een gegeven punt (herhaling)
Uitgangspunt
Cirkel met vergelijking ๐ฅ โ ๐ 2 + ๐ฆ โ ๐ 2 = ๐2 en een punt ๐(๐ฅ0, ๐ฆ0).
Doel
Bepaal de raaklijn aan de cirkel door het punt ๐(๐ฅ0, ๐ฆ0).
Oplossing (eerlijk delen)
(๐ฅ0โ๐)(๐ฅ โ ๐) + (๐ฆ0โ๐)(๐ฆ โ ๐) = ๐2
7. Poollijn
Definitie
Gegeven een cirkel ๐ถ: ๐ฅ โ ๐ 2
+ ๐ฆ โ ๐ 2
= ๐2
en een punt ๐(๐ฅ0, ๐ฆ0) buiten de
cirkel. De poollijn van punt ๐ ten opzichte van ๐ถ is de lijn door de punten waar de
raaklijnen uit ๐ de cirkel raken. Het punt ๐ heet de pool van de lijn ten opzichte
van ๐ถ.
Stelling
De poollijn heeft vergelijking (๐ฅ0โ๐)(๐ฅ โ ๐) + (๐ฆ0โ๐)(๐ฆ โ ๐) = ๐2
.
Bewijs
Laat ๐ด(๐ฅ1, ๐ฆ1) en ๐ต(๐ฅ2, ๐ฆ2) de snijpunten zijn van de cirkel met de poollijn. Voor
beide punten volgt uit de vergelijking van de raaklijnen aan de cirkel dat
(๐ฅ1โ๐)(๐ฅ0 โ ๐) + (๐ฆ1โ๐)(๐ฆ0 โ ๐) = ๐2
(๐ฅ2โ๐)(๐ฅ0 โ ๐) + (๐ฆ2โ๐)(๐ฆ0 โ ๐) = ๐2
Kennelijk voldoen beide punten de gegeven vergelijking. Dit betekent dat deze
vergelijking hoort bij de lijn door ๐ด en ๐ต.
8. Poollijn
Stelling (opgave 4.14)
Als het punt ๐ op poollijn van ๐ ten opzichte van ๐ถ ligt, dan ligt ๐ op de
poollijn van ๐ ten opzichte van ๐ถ.
Bewijs
De poollijn van ๐(๐ฅ0, ๐ฆ0) heeft vergelijking
(๐ฅ0โ๐)(๐ฅ โ ๐) + (๐ฆ0โ๐)(๐ฆ โ ๐) = ๐2
Omdat ๐ ๐ฅ1, ๐ฆ1 hierop ligt geldt dus
(๐ฅ0โ๐)(๐ฅ1 โ ๐) + (๐ฆ0โ๐)(๐ฆ1 โ ๐) = ๐2
Ofwel
(๐ฅ1โ๐)(๐ฅ0 โ ๐) + (๐ฆ1โ๐)(๐ฆ0 โ ๐) = ๐2
Maar hier staat nu juist dat ๐ ligt op de poollijn van ๐.
9. De macht van een punt ten opzichte van een cirkel
Definities
Gegeven een punt ๐ en een cirkel met middelpunt ๐ en straal ๐, dan heet
het getal ๐๐ 2 โ ๐2 de macht van ๐ ten opzichte van de cirkel.
De verzameling punten die dezelfde macht hebben ten opzichte van twee
cirkels heet de machtlijn van de twee cirkels (opgave 4.18 en 4.19)
Het punt waarvoor de machten ten opzichte van drie cirkels gelijk zijn heet
het machtpunt van de drie cirkels.
