EDLAB

Devices to support active experimental activitities of pupils

The Vision

Raising pupils' interest in learning, better knowledge fixation and improving the atmosphere in classes.

The current generation is closely-knit with information technologies and the technologies are part of their everyday lives. The children need to use what is close to them in the process of acquiring knowledge; something they have experience with and something that fulfills the famous Comenius' "learning through games".

The Solution

When using measuring devices in computer-aided experiments, the teacher has the opportunity to visualize the lectured passages of the curriculum, thus fulfilling the illustrative principle that directly affects pupils' attention span (this also applies to pupils with learning disabilities) and significantly extends it. When working independently with measuring systems, the pupil can choose the pace of work that suits him/her. They can slowly and carefully read the measured values and save them for later use. The pupil can bring up the results of each measurement and its course at any time. Using additional utility program add-ons, the pupil can use the built-in data analysis functions to fill in the protocol with transmitted measured values ​​in the form of tables and charts. Suddenly, the teacher appears not only as a rigorous examiner, but informs the process of acquiring knowledge from the position of a mentor and tutor. Pupils are encouraged to think independently, create hypotheses and find the right answer to the task with the support of the teacher. This method also has the motivation effect associated with the process of discovering the unknown. A no less important by-product opf this way of teaching is the increasing knowledge and skills in computer literacy.

Edlab hardware

EdLaB is a Czech provenance plant, manufactured by Connexia, s.r.o. Dětmarovice, the development of which involves teams of teachers and technicians from the Czech Republic, Poland and Slovenia. The EdLaB measuring device is connectable to a USB PC port, its skeleton is characterized by high durability suitable for school conditions. The device has ROHS and CE certificates. Approximately 150 attempts were made for teachers for subjects of biology, chemistry, physics, environmental education, geography and physical education for primary and secondary schools. EdLaB employs approximately 500 schools in the Czech Republic.

Basic characteristics:

The EdLaB - Digital Control Unit periphery, for which a special, simple scripting language has been created, is also used in the process of controlling electrical devices based on measured data - regulation of lighting, temperature, motor control, switches, etc.

There are 40 sensors currently available, characterized by high measurement accuracy. New types of sensors are being constantly developed. The measuring interface is designed using a reduction for the use of sensors produced by Vernier and C.M.A.

Sensors

Edlab – software

The interface is controlled by EdLaB software running on Windows XP or higher. The main features are autodetection of sensors, the possibility of configuration of new sensors, calibration of sensors, possibility of software change in the range of measurements. The measurement takes place in automatic mode, the user can set the measuring time, the sampling frequency, the trigger function can be used. The program allows you to graphically display outputs from 6 sensors simultaneously, enlarge individual parts of a graph, merge graphs into one view, data can be displayed in a table, basic statistical operations can be performed over the data. The program allows the approximation of measured data by linear, quadratic, logarithmic and exponential functions. From the point of view of didactics, the software is useful for processing reports from the measurement, allowing the user to insert their own data, notes, charts, tables and calculations from the measurements.
