Test - a method of measuring a persons ability or knowledge in a given domain.
assessment - an ongoing process that encompasses a much wider domain.
informal assessment - incidental, unplanned comments and responses from "coaching" your students and giving feedback
formal assessment - includes exercises or procedures specifically designed to tap into a storehouse of skills and knowledge.
Principles of language assessment;
practicality - a test should be written within means of financial limitations, time constraints, ease of administration and scoring and interpretation. norm-referenced tests the score is interpreted in relation to mean, median, standard deviation, and/or percentile rank. purpose is to place test-takers along a mathematical continuum in rank order. criterion-referenced tests are designed to give test-takers feedback on specific course or lesson objectives.
Reliability - test must be consistent and dependable. sources of unreliability can be the test itself, the administration of the test, the test taker, the scoring of the test.
Validity - the degree with which a test actually measures what it is intended to measure. can only be measured by observation and theoretical justification. content validity can be determined by observing if you can clearly define the achievement you are measuring. face validity is that the test appears to the student to test what it was designed for. construct validity is that the test taps into the theoretical construct as it is defined. authenticity is the degree of correspondence of the characteristics of a given language test task to the features of a target language task.
Washback - comment generously and specifically on test performance to students. provide information as to what they have done wrong to understand the feedback.
Kinds of tests;
Proficiency tests - a test aimed at tapping global competency in a language. types of tests include standardized multiple choice items on grammar, vocabulary, reading comprehension, aural comprehension and sometimes a sample of writing.
Diagnostic tests - designed to diagnose a particular aspect of a language. tests offer checklists of features for the administrator
Placement tests - purpose is to place the student into an appropriate level of section of a language curriculum or school. includes a sampling of material to be covered in the curriculum.
Achievement tests - related directly to classroom lessons, units or even a total curriculum. limited to particular material covered in a curriculum within a particular time frame.
Aptitude tests - a test given to a person prior to any exposure to the second language, a test that predicts a persons future success.
Practical steps to test construction - test towards clear, unambiguous objectives, from your objective draw up test specifications, draft your test, pilot the test in a trial run, revise your test, finalize your test, utilize feedback after administering the test, provide ample washback.
Transforming and adapting existing tests - facilitate strategic options for test-takers, establish face validity, design authentic tasks, distinguish between summative and formative assessment, work for beneficial washback.
Alternatives in assessment;
portfolios - a purposeful collection of students work that demonstrates to students and others their efforts, progress and achievements in given areas.
journals - specify to students what the purpose of the journal is, give clear directions, give guidelines on length of entries and other formal expectations, includes self-reflection, self-assessment language learning logs and responses to readings.
conferences - through conferences a teacher can assume the role of facilitator and guide. is a dialogue that is not to be graded. are formative not summative
observations - the ability to observe students as they perform. things to look for include interaction with classmates, frequency of student-initiated response, quality of teacher-elicited responses and evidence of listening
