Casus 4: Leerlingen met een tweetalige thuisomgeving
4. Conclusie en Discussie
4.4 Suggesties voor vervolgonderzoek
Eventueel vervolgonderzoek zouden allereerst grotere onderzoeksgroepen moeten ontwikkelen. Door de kleine onderzoeksgroepen van het huidige scriptieonderzoek kunnen de resultaten namelijk minder betrouwbaar geïnterpreteerd worden. Daarnaast dienen de deelnemers in meerdere delen van Nederland geworven te worden, zodat de resultaten van het onderzoek te generaliseren zijn.
In het huidige scriptieonderzoek zijn de gemiddelde leerlingen zonder risico op leesproblemen bij selectie met betrekking tot het familiaal risico meegenomen in het onderzoek. Dit is echter niet geval met betrekking tot het omgevingsrisico. Hier zijn namelijk alleen de experimentele leerlingen en de controle leerlingen in de analyses meegenomen. Aangezien er geen eenduidig effect te vinden is bij de prestaties van de experimentele leerlingen en controle leerlingen op het gebied van taalstimulering, zou het erg interessant zijn om te onderzoeken wat het effect van taalstimulering is op de gemiddelde leerlingen.
Bovendien zou eventueel vervolgonderzoek rekening moeten houden met de invloed van leerlingen met een familiaal risico op leesproblemen met betrekking tot taalstimulering. In het huidige onderzoek zijn deze leerlingen niet van elkaar onderscheiden, waardoor deze leerlingen de resultaten van de analyses beïnvloeden.
Verder zou eventueel vervolgonderzoek de mate van taalstimulering beter kunnen onderzoeken aan de hand van ouderrapportages. In dit scriptieonderzoek lijkt taalstimulering (gerapporteerd door de leerlingen) namelijk geen invloed te hebben op de leesvaardigheden van leerlingen. Dit in tegenstelling tot veel eerdere studies die gebruik gemaakt hebben van ouderrapportages (o.a. Frijters, Barron & Brunello, 2000; de Jong & Leseman, 2001; Bracken & Fischel, 2008).
