“From their earliest school experience, students draw life-shaping conclusions about themselves as learners on the basis of the information provided to them as a result of classroom assessments.”

- Stiggins, Student-Involved Classroom Assessment, Prentice-Hall, 2001, p.48.

Recall your own assessment experiences as students.

What kind of meaningful classroom assessment information do we want to provide to our students?

Purposes of AssessmentAccording to the Ministry of Education’s curriculum policy documents, the purposes of assessment and evaluation are to:

• improve student learning;• help teachers to determine students’ strengths and weaknesses in

their achievement of the curriculum expectations;• guide teachers in adapting curriculum and instructional

approaches to students’ needs, and;• assess the overall effectiveness of programs and classroom

practices.

The improvement of student learning is the most important focus of assessment.

Key Messages

Assessment is an ongoing awareness of students’ learning and needs, rather than an occasional event in the program.

Key Messages

Of all the assessment strategies, formative assessment is the most valuable strategy for supporting students’ learning and for promoting students’ independence and responsibility as learners.

Key Messages

Observation is the most efficient and effective way for teachers to assess students’ mathematical abilities, and is an integral part of all assessment strategies.

Key Messages

Teachers should use a variety of assessment strategies in order to assess students’ mathematical development as completely as possible.

Key Messages

Teachers should not provide a grade/mark/level on an individual assessment or a collection of assessments unless the grade/mark/level serves a clear purpose: to communicate achievement of curriculum expectations to students, parents, other teachers, and administrators.

Types of Assessment

Diagnostic AssessmentAssessment FOR Learning

• The collection of information that occurs before a unit or new teaching (e.g., lesson);

• enables teachers to determine student strengths and learning needs;

• enables teachers to build on students’ prior knowledge;

• provides direction for the adjustment and improvement to programs for individual students or for the whole class.

Gathering Diagnostic Information• Ask students to explain what they already know about a

concept or skill;

• Have students use manipulative materials to represent and explain a mathematical idea;

• Conduct brief, informal conversations with students about new ideas;

• Observe and talk with students as they solve a problem or complete a task that involves the concept or skill.

Provides ongoing day to day feedback for the teacher regarding the following:

• Identifying where to focus students’ attention and effort and encouraging progress and achievement of goals

• Monitoring of student learning, identifying areas of growth or concern and providing descriptive feedback

• Identifying the effectiveness of instruction and programming in order to modify and adjust it as necessary

What conclusions can be made from assessment?

Teacher’s Assessment

The student has difficulty understanding the problem (i.e., misread the question, omitted information - 22 legs), or selecting appropriate problem solving strategies.

14 7 chickens have 14 legs

Inference From Assessment

The student may have difficulty identifying important information when reading problems or lacks a strategy for selecting an appropriate problem solving strategy.

Next Instructional StepThe teacher models the problem solving process. The teacher reads and rereads the problem aloud, underlining important information and crossing out extraneous information. The teacher prompts the student restate the problem in his/her own words.

The teacher models how to develop a plan to solve the problem, suggesting appropriate tools and strategies. The teacher uses questions and cue to prompt the student.

The teachers asks the student to explain his/her thinking to determine whether he/she understand the problem.

Teacher’s Assessment

A grade 5 student has difficulty remembering the order of the steps when using the standard long division algorithm.

Inference from the Assessment

Based on this observation, what inference can you make about this student?

Inference From Assessment

The student may not understand, at the conceptual level, the procedure for long division.

Let’s Try a Question

Using the Rubric: Code the Student Exemplars

What Code is This?

Code 20Annotation:

Student demonstrates some understanding of the relationships between important elements of the problem; shows 11 quarters equals $2.75 and draws quarters to continue adding towards the target of $5.25. 13 more quarters does not give a total of $5.25.

Code 10Annotation:

Student demonstrates a minimal evidence of a solution process; draws 14 quarters with no justification and subtracts the 11 given to conclude 3 more.

What Code is This?

Code 30Annotation:

Code 40Annotation:

Student demonstrates a thorough understanding of the relationships between all of the important elements of the problem; shows groups of 4 quarters to make $1.00; uses diagram to show an additional 10 quarters are needed to make $5.25.

• Analyse students’ written work

• Observe students as they work on learning tasks

• Conduct conversations with students about their learning

Planning for InstructionPlanning for Assessment

• Usually carried out at the end of a unit, term, semester or year;

• informs teachers’ formal judgments about students’ achievement to be used in reporting;

• helps confirm what students know and can do and whether they have achieved the curriculum expectations.

Summative Assessment Assessment OF Learning

Summative Assessment…

Examples:

• Interviews • Problem solving situations• Performance tasks• Paper-Pencil Tests

Evaluation is the summative process of:

• judging the quality of student work on the basis of previously established criteria

• assigning a value (letter or percentage grade) to represent that quality.

Evaluation

What to do if Students Responses Don’t Follow a Logical Pattern

- Realize that no assessment can ever provide perfectly accurate data about a student

- Drop some items because they are deemed to be invalid

- Rethink the classification of specific items

- Meeting individually with students

Evaluation Decide early which assessments will form the basis for

grades and which will be used in a formative way

Compare student performance against criteria and standards

No single measure will give you all the information you need

Communicate your explicit expectations about both quantity and quality to students

Involve students in the selection process

Assessment AS Learning

• Focuses on the active involvement of students in the assessment of their own learning;

• Students personally monitor their own learning and use the feedback to adjust or adapt their understanding;

• Emphasizes students as critical assessors who can use metacognition in the self-assessment process.

Let’s Review:

• Diagnostic (Assessment for learning): is assessment helps to determine entry points.

• Formative (Assessment for learning): is assessment helps to promote learning and progress.

• Summative (Assessment of learning): is assessment reflects student achievement at a given time in a specific context e.g. at the end of year to determine placement or programs.

Knowing what ingredients you already have and may require to make excellent soup, that’s diagnostic;

When the cook tastes the soup, that’s formative;

When the guests taste the soup, that’s summative.

When they think it’s good or bad that’s evaluation.
