What is Microcomputer-Based Laboratory

Chapter 18
Handbook of Research on Driving STEM Learning With Educational Technologies
Laboratory session supported by a computer, an interface and probes to collect data in real time. Students are able to experiment real physical phenomena, manipulate data and observe directly the nature´s behavior. At the present, electronic devices are more sophisticated and easy to handle, this allow to substitute a desktop computer with smaller devices.

Abstract
This study reports the outcomes of comparing three methods to carry out a physics laboratory with active learning strategies: Tutorials in Introductory Physics (Tutorials) and RealTime Physics (RTP). A sample of 476 students was divided into three groups, about one third of the students used Tutorials, another third used RTP, and the last third used RTP with graphing calculators and probes. A multiple choice test was used to find that the three groups had statistically-significant differences on conceptual understanding of current concepts. Additionally, it was found differences in gains among the three groups using a multiple-choice pretest and posttest. With an analysis of misconceptions it was found that an important portion of students still holding misconceptions. The change of instruction seems to affect conceptual understanding when students have to analyze difficult circuits. Besides, it was found that students still holding misconceptions, they continue using terms like current and voltage interchangeably.
