The Construct of Reading Literacy in PISA
5
“the ability to understand, use and reflect on written texts in order to achieve one’s goals, to develop one’s knowledge and potential, and to participate effectively in society” (OECD, 1999)
6
Reading Literacy in PISA Process of ReadingContent of ReadingContext of Reading 3 dimensions of reading
7
The Process - Five aspects of reading Retrieving information Broad understanding Developing an interpretation Reflecting on content Reflecting on form Retrieving information Interpreting Reflecting and Evaluating content and form
8
The Content – 2 categories, 11 types Text ContinuousNon-Continuous Descriptive Narrative Expositive Argumentative Injunctive Charts and Graphs Tables Diagrams Maps Forms Advertisements
9
The Context Personal Public Occupational Educational
10
The Construct of Reading Literacy for PISA Content (Format, Type) Context (Personal, Public, Occupation, Education) Process (retrieving, interpreting, reflecting)
11
The Design of PISA Literacy Assessment
12
The Hong Kong Sample PISA sampling procedure closely followed 140 schools 4405 15-year-old students
13
The assessment materials 37 stimulus texts 141 reading tasks 9 equal sets Chinese version verified by PISA
14
Formats of Response Multiple choice questions Complex multiple-choice items Closed-constructed responses Short responses Open-ended responses
15
Reporting of Reading Literacy Performance Four different proficiency scales Retrieving information sub-scale Interpreting text sub-scale Reflecting on and evaluating text sub-scale Combined scale These scores then mapped on to a five-level proficiency scale
16
Descriptors of skills demonstrated at each level of the three reading proficiency sub-scales (Appendix 3) Proficiency Level Retrieving InformationInterpretingReflecting Level 5 Locate and possibly sequence or combine multiple pieces of deeply embedded information, some of which may be outside the main body of the text. Infer which information in the text is relevant to the task. Deal with highly plausible and/or extensive competing information. Either construe the meaning of nuanced language or demonstrate a full and detailed understanding of a text. Critically evaluate or hypothesise, drawing on specialised knowledge. Deal with concepts that are contrary to expectations and draw on a deep understanding of long or complex texts. Level 3 Locate, and in some cases recognize the relationship between pieces of information, each of which may need to meet multiple criteria. Deal with prominent competing information. Integrate several parts of a text in order to identify a main idea, understand a relationship or construe the meaning of a word or phrase. Compare, contrast or categorize taking many criteria into account. Deal with competing information. Make connections or comparisons, give explanations, or evaluate a feature of text. Demonstrate a detailed understanding of the text in relation to familiar, everyday knowledge, or draw on less common knowledge. Level 1 Locate one or more independent pieces of explicitly stated information, typically meeting a single criterion, with little or no competing information in the text. Recognize the main theme or author's purpose in a text about a familiar topic, when the required information in the text is not prominent. Make a simple connection between information in the text and common, everyday knowledge.

Descriptors of performance by students at Level 1 and Below Level 1 Level 1: “capable of completing only the least complex reading tasks, such as locating a single piece of information, identifying the main theme of a text or making a simple connection with everyday knowledge.” Below Level 1 : “not capable of the most basic type of reading that PISA seeks to measure……Such students have serious difficulties in using reading literacy as an effective tool to advance and extend their skills in other areas.”

Summary of HK students’ overall performance on reading literacy HK has a relatively high performance (525, Proficiency Level 3, 6th) in reading literacy comparing with other countries Comparing with other countries, HK has a relatively small percentage (10%) of very proficient readers and poor readers The high rank of HK is largely due to the large percentage of students achieving Level 3 (33%) & 4 (31%)

Summary of HK students’ performance on the reading sub-scales HK students generally do better than OECD countries on the sub-scales HK students maintain their good performance on “reflecting and evaluation” HK high-achieving students gradually improve their performance from retrieving to evaluating, while low achievers showed a reversed pattern of results HK students’ performances show a greater disparity across the sub-scales than that of the OECD countries

Summary of HK students’ Performance across contexts of use HK students are better at texts written for educational (68%) and occupational Purposes (69%) than for personal (65%) and public uses (63%) HK students perform exceptionally better than OECD average on “Occupational” texts

Conclusion and Discussion
40
Comparatively speaking, HK lags behind in the number of very proficient readers. HK students are relatively good at high order reading skills. HK students are particularly good at argumentative text, but weak at advertisement. HK students perform better on “educational”, “occupational” than on “personal” and “public” context of reading. HK education is successful in producing a majority of students with an above-average reading literacy. Are the results contradictory to our perception? How good do we want our students to be?
