Millikan. MicroSIFT Courseware Evaluation.
Northwest Regional Educational Lab., Portland, OR.
THE FOLLOWING IS THE FULL TEXT OF THIS DOCUMENT (Except for the Evaluation Summary Table): VERSION: Copyright 1979. PRODUCER: Mentor Software, Inc., Box 8082, St. Paul, Minnesota 55113. EVALUATION COMPLETED: March 14, 1982 by the staff and constituents of Texas Region X Educational Service Center. COST: $19.95. ABILITY LEVEL: Grade 11+. SUBJECT: Physics: Millikan Oil Drop Experiment. MEDIUM OF TRANSFER: 5-1/4" flexible disk. REQUIRED HARDWARE: Apple II or Apple II+ with one disk drive. REQUIRED SOFTWARE: Applesoft, DOS 3.3. INSTRUCTIONAL PURPOSE: Standard instruction. INSTRUCTIONAL TECHNIQUES: Problem solving, simulation. DOCUMENTATION AVAILABLE: The computer program contains student instructions. Supplementary materials include the following: suggested grade/ability level(s), instructional objectives, prerequisite skills/activities, program operating instructions, teacher's information and student worksheets. INSTRUCTIONAL OBJECTIVES (Stated): Students will be able to describe the principles involved in the Millikan Oil Drop Experiment, and given the necessary experimental data, students will determine the charge on a single electron. INSTRUCTIONAL PREREQUISITES: (Inferred): Instruction in concepts underlying the measurement of an electron's charge. CONTENT AND STRUCTURE: This package provides a simulation of the Millikan Oil Drop Experiment. By varying voltage across plates, students find conditions that keep drops stationary. Listing and alteration of this program are not permitted. ESTIMATED STUDENT TIME REQUIRED: (Approximately) 20-30 minutes. POTENTIAL USES: The program may be used in a classroom setting to provide practice in working up a famous experiment without the hazards and costs of the necessary equipment to perform this complex experiment. The program may also be used as a demonstration, a pre-lab activity, or as an alternative to the school's actual laboratory experiment. MAJOR STRENGTHS: The program is an example of the use of a computer for an activity which is difficult to set up and carry out and for which a number of repetitions in a short time period is desirable but difficult using actual apparatus. MAJOR WEAKNESSES: The Millikan worksheet should have a space for percent of error. EVALUATION SUMMARY: Evaluators indicate they would use or recommend use of this package with little or no change.
