Project 4: Reading and writing development

Assessing the reading and writing proficiency of at-risk adolescents

in multilingual contexts

Roel van Steensel, Ron Oostdam, Amos van Gelderen and Mirjam Trapman

Study into Adolescent Literacy of Students At-risk

SALSA

2Roel van Steensel, EARLI 2009

Project SALSA

• Large groups of students in secondary education lag behind in literacy skillsOECD (2001)

• Relatively little is known about the factors that influence at-risk students’ literacy developmentCurtis (2002)

• Hence: Project SALSA

Project SALSA

• Central research questionWhich factors contribute to/impede the reading and writing development of at-risk adolescents in multilingual contexts?

• Sample– Lower tracks of prevocational secondary education (vmbo): basic

and middle-management program– Grades 7, 8 and 9 (age range: appr. 12-15)– 30% lowest scoring on CITO End of Primary School Test– Year 1 (2007/08): N=63– 32 monolinguals, 31 bilinguals (based on student questionnaire)

• International contextParallel projects in Canada en Switzerland

5Roel van Steensel, EARLI 2009

The test

• Newly developed literacy test:– Reading: text comprehension– Writing: text production

• This presentation: (construct) validity of the reading test

6Roel van Steensel, EARLI 2009

The test

• 9 reading tasks

• Text selection on the basis of:

– Text type: narrative, expository, instructive, argumentative

– Medium: school books, newspapers/magazines, internet, ‘official documents’ (house rules)

– Subject: context-neutral, relevant for the target group

The test

• Item construction on the basis of hypothesized subskills:

– Retrieving: retrieving relevant details from the text

– Interpreting: making inferences from shorter passages in the text (e.g. cause-effect relationships)

– Reflecting: reflecting on larger passages/the text as a whole

10Roel van Steensel, EARLI 2009

Validity study

• Messick (1989) - aspects of (construct) validity:

– Construct (ir-)relevance: does the test only reflect aspects of the construct to be measured? Or are the test results influenced by variables irrelevant to the construct?

– Internal structure: can (theoretical) expectations about relations between items be confirmed?

– External structure: can (theoretical) expectations about relations with other measures be confirmed?

11Roel van Steensel, EARLI 2009

Validity study

• Test administered to 200 students in the lower tracks of prevocational secondary education (school year 2007-08)

• Additional tests administered to a subsample of 63 students

12Roel van Steensel, EARLI 2009

Construct (ir-)relevance

• Assumption: difficulty of the tasks is determined by difficulty of the texts

• Comparison between:– Text difficulty measured by Flesch/Douma readability

index– Task difficulty indicated by mean task score as % of the

maximum task score

Construct (ir-)relevance

• INS1 en INS2 are both discontinuous texts:– INS1 is a set of house rules

discontinuity makes the task easier

– INS2 is a website

discontinuity makes the task more difficult

Internal structure

• Do the data show a:– 1-factor model?– 3-factor model?– 2-factor model?

• Confirmatory factor analysis using Structural Equation Modeling (EQS 6.1)

• Individual test items were combined into 6 parcels (RTR1, RTR2, INT1, INT2, RFL1, RFL2)

External structure

• Assumption: text comprehension is facilitated by:

– Well-developed decoding skills

– A rich vocabulary

– Well-developed morpho-syntactic skills

– A good working memory

– (Metacognitive) knowledge of reading and writing

• And: text comprehension is associated with IQ

22Roel van Steensel, EARLI 2009

Conclusions: support for validity?

• Construct (ir-)relevance:

Task difficulty largely corresponds with text difficulty– Exceptions (INS1, INS2) are explainable

• Internal structure:

No support for the presence of subskills

Data do show that the test measures one construct

• External structure:

Substantial correlations with other skills– Exception (decoding skills) is explainable
