The Interview for Student Reasoning – IfSR, is an online on-demand diagnostic numeracy assessment.

The IfSR informs teachers of the way a student reasons and uses their mathematical knowledge.

What is IfSR - Number and place value?

IfSR - Number and place value or IfSR-NP is an online assessment that enables a teacher to gain insights into how a student reasons and works with numbers and place value including decimals and patterns.

From the insights a teacher can establish where students are in their learning in order to target their teaching.

The tool enables a teacher to monitor student progress through the use of PLAN2.

There are 4 sections in IfSR-NP.

Each section has 3 subsections, with 4 subsections in section 4.

All items are aligned to the Mathematics K-10 syllabus and the National Numeracy Learning Progression.

Who is IfSR-NP for?

The assessment is designed to be delivered flexibly to assess individuals or groups of students K-10 to identify their reasoning skills in number and place value.

You can select students who you would like to gather more information on. It is designed to supplement existing school practices and inform your decision making within the teaching and learning cycle to identify how students construct their mathematical understandings and to help you tailor your teaching more specifically to student needs.

How do I administer the online assessment?

Before you begin the assessment, read the assessment guide, familiarise yourself with the online assessment tool and prepare the necessary materials.

Select the year level, class or group.

Select the student, then choose to begin or continue the assessment for the student you are working with.

Confirm the student and section by selecting the ‘Start’ or ‘Continue’ button, to start or resume the assessment.

The IfSR-NP assessment has been modularised to give you flexibility in assessing sub-skills for targeted teaching.

This allows you to select the starting point when beginning each section.

When administering each question you will see: the sub-section being assessed, any materials that may be required, and instructions for the task.

Read the questions to the student that are marked with a speech bubble icon.

How are responses recorded in the tool?

Record student responses by selecting an option from the response panel.

You can record a comment, noting the student’s behaviour.

This will assist you when analysing the results.

Select the ‘Flag’ button to mark and draw your attention to particular tasks.

Select ‘Next’ to move to the next question.

Responses will be saved automatically.

How do I navigate the assessment?

The progress bar displays the count of completed tasks out of the total number of tasks for that section.

Move to a specific task by selecting ‘Go to’.

How do I review individual student progress in the IfSR tool?

View the number of questions in the sub-section and navigate to a specific question if needed.

Answered questions display in blue, not answered in white, and flagged with a black triangle in the top left corner.

Close the progress bar to return to the assessment.

To pause the interview without completion, select the ‘Exit’ button in the top right corner.

This will save your progress and close the assessment screen.

How do I finalise responses and lodge the assessment?

To lodge the assessment select ‘Finish Interview’.

Lodgement will not be possible until all tasks have been responded to.

Navigate to any unanswered tasks, or mark all unanswered tasks remaining as ‘Not given’, noting a reason and any additional comments.

You can also ‘Save and exit’ to lodge responses at a later time, or finalise student responses by selecting ‘Lodge’ once all responses have been recorded.

Once lodged, student responses cannot be modified.

How do I access student assessment analysis and responses?

View the status of an assessment and access a student analysis for each section assessed from the main page of the online tool.

Here you can continue, re-assess or begin a new assessment.

Re-assessment of a section can occur at any time.

A Student Assessment Analysis can be downloaded in the online tool for each section assessed.

The analysis can assist in making decisions about the next steps in learning to meet the needs of individual students.

Where else can I analyse student responses?

IfSR-NP maps student responses to the National Numeracy Learning Progression in PLAN2.

Direct links to class observations and cohort snapshot are available via the 'Class analysis' button.

The Area of focus template in PLAN2 is aligned with IfSR-NP to enable you to target your teaching.

Advice on use

IfSR - Number and place value (IfSR-NP) is part of a suite of teacher-led online numeracy assessments administered by the classroom teacher to individual students through one-to-one interviews. They can be administered at any point in time to reveal what a student knows, ways a student reasons with and thinks about mathematical tasks, and as a tool to investigate the gaps in a student’s mathematical knowledge.

• The assessment is modularised to give teachers flexibility in assessing sub-skills for targeted teaching.
• The administration is flexible and adaptable to enable teachers to gather information on a student's conceptual knowledge in numeracy.
• IfSR - NP does not need to be administered within a specific timeframe or from beginning to end.
• Teachers tailor the administration of the assessment to suit the needs of individual students by selecting either a section, sub-section or specific tasks. For example, a teacher may select to administer only a small group of tasks in one section.
• The teacher decides on tasks and/or sections by reviewing existing assessment such as classroom observations and/or teacher judgement.

This resource may be used across the curriculum where it supports the teaching and learning of numeracy skills aligned to syllabus outcomes.

For further advice on use, please see the IfSR-NP assessment guide.

Differentiation

When using these resources in the classroom, it is important for teachers to consider the needs of all students, including Aboriginal and EAL/D learners.

EAL/D learners will require explicit language support and scaffolding, informed by the Enhanced EAL/D enhanced teaching and learning cycle and the student’s phase on the EAL/D Learning Progressions. For further information visit the English as an additional language or dialect education webpage.

Learning adjustments enable students with disability and additional learning and support needs to access syllabus outcomes and content on the same basis as their peers. Teachers can use a range of adjustments to ensure a personalised approach to student learning.

A range of tools to identify, assess and challenge high potential and gifted learners are available to support teachers in the classroom. Identifying contributors to achievement helps teachers identify and target areas for students’ growth and improvement. A differentiation adjustment tool can be used to plan effective teaching strategies.
