The Digital High Stakes Assessment Programme in Cambridge University Press & Assessment is developing digital assessments for UK and global teachers and learners. In one development, the team are making decisions about the assessment models to use to assess computing systems knowledge and understanding. This research took place as part of the…

This learning module for a secondary electronics course contains two lessons that teachers can use to help students do the following: (1) access an Apple II computer with a PZ-90 interface to read input ports and send information to output ports with the aid of a computer program; and (2) demonstrate the use and relationship of binary numbers in…

This learning module for a high school course in graphic communications is designed to introduce students to the Aldus Page Maker 3.0 software for desktop publishing. The module activities allow students to use the software to prepare a two-page publication. The six sections of the module are the following: module objectives, content outline,…

This manual is the first of three manuals for teaching repair skills to entry-level microcomputer service technicians. Although it focuses on basic computer repair skills, it also highlights the people skills needed by service providers. The manual contains 11 units. Each instructional unit includes some or all of these basic components:…

This learning module for a high school architectural drafting course introduces students to the use of Claris CAD (Computer Aided Drafting) to develop a floor plan. The six sections of the module are the following: module objectives, content outline, teaching methods, student activities, resource list, and evaluation (pretest, posttest). Student…

This learning module for a high school metals and manufacturing course is designed to introduce the concept of computer-assisted machining (CAM). Through it, students learn how to set up and put data into the controller to machine a part. They also become familiar with computer-aided manufacturing and learn the advantages of computer numerical…

The relationship between the multiple-choice and free-response sections of the Computer Science and Chemistry tests of the College Board's Advanced Placement program was studied. Confirmatory factor analysis showed that the free-response sections measure the same underlying proficiency as the multiple-choice sections for the most part. However,…

This document contains 20 competency-based examinations with student and instructor manuals for computer science microcomputer-related occupations. For each of the examinations, the student manual contains the following: the competency, the performance objective, directions, the facility to be used, the materials and equipment needed, a space to…

The relationship of an expert-system-scored constrained free-response item type to multiple-choice and free-response items was studied using data for 614 students on the College Board's Advanced Placement Computer Science (APCS) Examination. Implications for testing and the APCS test are discussed. (SLD)

Restricted factor analysis shows that the multiple-choice and free-response sections of the Computer Science and Chemistry Advanced Placement examinations (College Board) measure the same proficiencies for the most part. There is a small degree of multidimensionality because of local dependence among free-response items. (SLD)

The use of constructed response items in large scale standardized testing has been hampered by the costs and difficulties associated with obtaining reliable scores. The advent of expert systems may signal the eventual removal of this impediment. This study investigated the accuracy with which expert systems could score a new, non-multiple choice…

This study examined the relationship of a machine-scorable, constrained free-response computer science item that required the student to debug a faulty program to two other types of items: multiple-choice and free-response requiring production of a computer program. The free-response items were from the College Board's Advanced Placement Computer…

Computer learners often develop explanations of events they observe during training. Recent work on generalization suggests that explanations may be valuable in permitting learners to develop generalizations from one or a few examples. This study explores the idea by describing four generalization paradigms in which explanations play a part:…

New developments in the use of automatically scorable constructed response item types for large-scale assessment are reviewed for five domains: (1) mathematical reasoning; (2) algebra problem solving; (3) computer science; (4) architecture; and (5) natural language. Ways in which these technologies are likely to shape testing are considered. (SLD)

The accuracy with which expert systems (ESs) score a new nonmultiple-choice free-response test item was investigated, using 734 high school students who were administered an advanced-placement computer science examination. ESs produced scores for 82 percent to 95 percent of the responses and displayed high agreement with a human reader on the…
