GloSS (Global Strategy Stage Assessment) |
| Assessment Area |
Mathematics-Numeracy
|
| Year level |
0-10 |
| NZ origin? |
Yes |
| Standardised? |
No |
| Administration to individual or group? |
Individual |
| What does it assess? |
It provides a global strategy stage across the operational domains of the numeracy project i.e. addition/subtraction, multiplication/division, proportions/ratios. |
| Purpose |
Quick identification of the global stage students have reached in number strategies. Strategies are the mental processes students use to estimate answers and solve operational problems with numbers. |
| Validity |
Items are tested for validity. |
| Reliability |
There is evidence of test/retest reliability. |
| What measures does it give? |
Stages for operational strategies which are linked to curriculum levels. |
| How long does it take to administer? |
Depends on the stage of the student, from 5 to 20 minutes. |
| How much training is needed? |
Careful training in test administration and assessment. |
| Scoring and data analysis |
A strategy stage/curriculum level is identified. A record sheet for each student tracks their progress longitudinally. A document of expected levels of achievement enables an assessment of whether students are at risk, a cause for concern, achieving at or above expectations or high achievers. |
| Does it provide 'what next' strategies? |
Yes , there are activities suggested for each stage in the Numeracy Development Projects books, available from the NZ Maths website. |
| Is it available in te reo Maori? |
Yes , there are versions of the test in te reo Māori. |
| Cost? |
No cost. Project materials can be accessed on the NZ Maths website. |
| Author, date of publication and publisher |
Materials for the Numeracy Project were written and published through the Ministry of Education from 2002. Revised GloSS forms were uploaded in June, 2013, informed by testing undertaken by NZCER. |
| Availability |
Materials are available from the NZ Maths website. |
| Further Information |
The interview consists of a series of questions that increase in difficulty and includes questions in all three strategy domains. Students move through these questions until they become too difficult for them to answer correctly. The assessment materials include:
- the series of questions you need to ask
- instructions about the actions you need to take, the words you need to say and the decisions you need to make at key points in the assessment
- a set of cards containing the questions to use with students
- recording sheets to document students' strategies for solving problems during the interview
- a student record sheet which can be used as a record of an individual student's progress over several years.
Multiple forms of the interview are available so that students do not become too familiar with the questions. |
