Involving High School Students in Constructing and Using Devices for Automation of Chemistry Laboratory


Computerized systems which include data loggers and sensors have been introduced recently in high school chemistry laboratories. The systems provide automation of collecting, processing, and communicating data, however hands-on manipulations are performed manually. This paper proposes additional automation of basic manual laboratory operations and construction and use of two devices, developed in our study: an automatic titrator, and a computer controlled dispenser. We present results of pilot implementation of the proposed approach in high school chemistry laboratory classes. As found, the use of the automation devices enabled to save time needed for performing laboratory work and devote it to inquiry activities. The automation devices increased accuracy and precision of the measurements. The students participated in the study noted that experiments in the proposed automated environment required less time, were more accurate, convenient and safety. They appreciated the opportunity to use advanced technology and have more time for inquiry activities.


Rapid development of automation technologies cardinally changes experimentation in chemistry research laboratories1. Information management systems automate collecting and analyzing data of chemical experiments and communication of results thereby freeing laboratory stuff from routine manual operations.

Laboratory automation courses have been introduced in undergraduate and graduate chemistry curricula2. A number of papers report on applying industrial titrators3 or constructing an automated titrator based on industrial automated devices, such as an automated pipette4, a metering pump5, or a computer-controlled syringe pump6. Some earlier studies reported original prototypes of construct constant rate burettes.

Recently the automation trend has involved high school chemistry laboratories. In Israel the Advanced Chemistry discipline includes a unit "Computerized Laboratory" in which the learning environment provides to students automation in experimental data collection and analysis by means of sensors, data loggers and computers7. Educational studies indicated the positive effect of this practice on fostering higher order thinking skills of the students.

In this study we constructed an automatic titrator and a computer controlled dispenser and followed up their use by high school students in chemistry laboratory experiments. The Student Learning Environment Inventory (SLEI)8 was employed in order to examine students' perceptions of a learning environment which integrates the automation devices in basic chemical experiments.
