Instructional and implicit objectiv

Instructional and implicit objectives.
Conditions that call for implicit objectives.
Some situations call for implicit objectives. First, implicit objectives may provide general guidelines or act as reminders to teachers that some goals are important even though their measurement may not be. For example, teachers may want children to learn “to think on their own.” This may not be a part of any structured lesson, but it can be a byproduct of how the teacher treats students and how lesson are presented even though no formal attempt is made to assess proficiency. Nothing, of course, prevents teachers from specifying what behavior the are willing to accept as evidence that students do “think on their own” and thus writing instructional objectives, but the fact that they can do so does not argue that they should.
Second, some objectives are important, but they measurement may not always be feasible or necessary. Teachers often have little control over what students do at home or what they will do as adults, but this does not mean that teachers are concerned only with what students do in school. The art cr shop teacher, for example, may want students to learn to use leisure time wisely but may have no intention of directly measuring wheter students have accomplished that objectives. If teachers are not planning to measure student attainment of an objective, there is no purpose in stating that objective in instructional terms.
Third, implicit objectives can form the basis for instructional objectives. By beginning with an imlicit objective, the teacher can generate different instructionally stated objectives that are tied together by a common element. For example, if teacher want to teach students how to think for themselves and if they want to hold themselves accountable in this regard, they could accept any one or all the following as evidence that they had been succesful:
• The student orally defends a political and social belief even when attacked by an authority figure.
• The student goes to the library to gather evidence to support a belief.
• The student questions statements found in a textbook.
Although these pbjectives differ from each other, they could all be summarized by an implicit objective such as “students think on their own.”
Fourth, implicit objectives may be more communicable to the public than instructional objectives. An objectives such as “the student will be able to read critically” may make more sense to parents than would “the student will be able to read critically by supporting an opinion with four facts found in specific story.” The behavior, though it is more specific and measurable, might not be information that parents desire or understand.
Fifth, implicit objectives may be useful to implement the writing of items that operationally define the attribute being measured. In thid case, test perfomance is specified as acceptable evidence that the objective has been obtained. Instead of describing verbally what the behavior is, the test itself may define the operations uswed to produce it. For example, suppose a teacher who wants to measure “the ability to discriminate facts from opinions” develops a series of paragraphs and asks students to list “facts” on one side of the page and “interpretations” on the other. This test describes clearly what the teacher wants the students to do; it defines the students task.
The difficulty with this approach is that most test are samples of different behaviors, traits, skills, or abilities. If the teacher provides only the test itself, it might be difficult or impossible to determine from what domain (a domain consist of a complete set of items tied closely to rules for generating those items. The rules for generating these items are specified on page 76-77.) these items were being sampled. Consider the following ten addition problems:
What do thes items measure? The addition of single-digit whole numbers whose sums are equal to or less than 15? Or perhaps the addition of any two single-digit whole numbers from 0 to 9? It is important to specify what these ten items represent if teachers want to include more items of the same type. Given the implicit objective “the student will know how to add two single-digit whole numbers,” the universe of possible items would be delineated, and the teachers could add more items to the samples and disregard wheter the sums of the two numbers were equal to or less than 15.
Immediate and ultimate objectives.
.................................................................................................................................................................
Many school activities are designed to prepare the students for future events such as marriage, employment, managing leisure time in four-fay workweek, and voting intelligently. Measuring the efectiveness of a curriculum in meeting these long-range objectives would require expensive and complex procedures. In some instances teachers might have to wait a considerable time before the student is ready for marriage or a job or is capable of voting. Because the school has little influence over what adults do, it ussually concerns itself with more immediate objectives over which it has some control.
Although teachers annot check directly on their effectiveness in teaching ultimate objectives, they can and should be certain that students have learned those behaviors within their ability and time limitations to teach. Thus, although “intelligent wrong” could not easily be measured by teachers, it it possible to make certain that students understand the immediate issues related to voting—the various political parties, advantages and limitations of various forms of government, the historical conditions that lead to social unrest, and so forth.
In recent years students have questioned the relevance of some aspects of the currivulum. Their charge is valid when teachers assign such tasks as “memorize the names of all vice-presidents of the United States” or “memorize a list of 70 adverbs” (these examples, by the way, are not contrived) without explaining their importance. Sometimes close examination confirms that an objective is picayunish; in other cases, presenting the rationale for a topic’s unclusion in the curriculum might make it more palatable.
Restricted and inclusive objectives.
Restricted objectives specify the content of single item; inclusive objectives permit the measurement of more than one item.
Some objectives are so restricted that they are practically equivalent to the test item itself; others are more broadly stated to allow for the inclusion of numerous sample of behaviors from the same designated domain. Some examples ef restricted and inclusive objectives are listed in Table 3.1. examine the list of restricted objectives. Each of the three examples contains objectives. Each of the three examples contains objectives that, when taken separately, closely approximate a test item. Thus, “add 1+1” could by itself be transformed into a test item by asking the student to write the answer to that problem on a sheet of paper. However, when all the addition objectives are considered together, they completely describe the inclusive objective “adds group of two single-digit whole numbers from 1 to 9.” The same line of reasoning applies to the second example. One could write six separate objectives to represent all primary and secondary colors or write the more inclusive objectives “orally identifies two examples, the inclusive objectives completely encompass their restricted counterparts.
The third example is different from the first two in a number of ways. First, the inclusive objective does not specify which facst or stories will be selected for the student to recall. Second, whichever ones are selected will not comprise the universe, or totality, of all possible stories that could have been selected. Third, if teachers werre given only the restricted objectives, they might have difficulty determining the more inclusive one.
Only inclusive objectives need be written by the teacher if the restricted counterparts are completely enumerated, as in the first two examples in Table 3.1, because these objectives contain all elements commong to the restricted objectives. However, if the inclusive objective can be measured by many different restricted objectives, first write the inclusive objective and then indicate what specific restricted samples will be used.
One other point should be made. If a restricted objectives is not a part of a clearly defined inclussive objective, the teacher should reconsider its value for the student. For example, knowing the names eks is not by itself a particularly important objective. Whatever importance it has is gained by being related to a more inclusive objectives, such as teaching children how to read for detail.
Research evidence regarding the use of objectives.
As discussed in Chapter 1, objectives are a necessary in teaching, whatever they are written and given to students. Every assignment given by a teacher, for example, is designed to lead to student improvement. Determining whether improvement has occured requires knowledge of what the teacher is trying to accomplish. At least insofar as evaluation in concerned, knowledge of the teacher’s objective is acrual.
Studies comparing the effects of objectives on student achievement, however, are beset with methodologic problem. First, determining if students pay attention to objectives is difficult (to paraphrase the adage: You can lead the students to objectives, but you can’t make them learn). Second, no one would claim that objectives will be met if the entering behavior required of students is at an inappropriate level. Giving students objectives for a very simple task means that the effects of objectives, if any, would be small. Third, the effectiveness of objectives depends on the adequacy of the instructional strategy. An ineffect
