The purpose of this article is to present a battery of three new systems for measuring Academic Learning Time-Physical Education. All three systems incorporate updated features and unique observational technologies for coding this student process variable in physical education. The first system uses analogue chronometry to make duration recordings of student behavior. The second system uses the Data Myte 801 electronic recorder for data collection. The third system introduces the first microcomputer-based data collection system for ALT-PE, considered to be the forerunner of many more such systems in the near future.
