Digital Laboratory for the Chemistry Classroom (Student) with Methodological Guide and AI-Powered Digital Course

• Purpose: a teaching aid for collecting, processing and visualising experimental data; student laboratory, practical and research work in the chemistry classroom and in other science and mathematics subjects
• Configuration: student set — sensors for acidity, conductivity, temperature, gas pressure and optical properties of solutions, for work at a student desk individually or in a small group
• Number of sensors: 6 (5 types; temperature sensor — 2 pcs)
• Sensor type: wireless, self-contained, working without additional devices or wires; a datalogger or other analogue-to-digital converter is not required to transfer readings to a computer or tablet
• Readout on the sensor: own colour LCD screen, 1.8 in diagonal, showing the current value with its unit at the moment of measurement
• Data acquisition: real-time measurement data from the laboratory set-up, uploaded and displayed on the end device (screen, web platform) for further use and processing by students on the AI-powered electronic platform
• Data transfer: wireless, simultaneous reading from several sensors, to a computer, mobile device or cloud service, automatically and without manual entry
• Software: displays data as tables and graphs, exports data to spreadsheet editors and other programs
• Interface language: Ukrainian by default, English as an option
• Digital course volume: 70 academic hours
• AI assistant: integrated into the platform, built on retrieval-augmented generation
• Licence (right of access) to the software and materials: 12 months

The digital learning materials and the AI assistant are an integral part of the set and are supplied with it; access is provided on the edu.unowa.eu platform.

The AI assistant is a separate tool of the digital course, integrated into the learning management system and built on retrieval-augmented generation: it forms its answers from a localised knowledge base aligned with the national curriculum of Ukraine. Data from the sensors reaches the platform automatically, without manual entry, so full-scale digital investigations can be run and analysed there. The assistant uses generative artificial intelligence.

The digital laboratory is a modern educational solution that combines software, multimedia content and elements of generative artificial intelligence to support inclusive and engaging learning.

AI Assistant Functions

• Task selection: automated selection of research tasks and experiments matching the topic of the lesson
• Methodological support: step-by-step description of the procedure for conducting experimental research
• Error analysis: identification of typical student errors and personalised recommendations for correcting them
• Tasks of different difficulty: selection of tasks of different difficulty levels according to the students' level of preparation
• Reports and conclusions: support in compiling reports on research results and in structuring the conclusions drawn from experiments
• Knowledge base: operation on a localised knowledge base aligned with the national curriculum of Ukraine
• Licence: right of access to the software and materials valid for 12 months
• Language: platform interface in Ukrainian by default, English interface as an option; content and learning materials in Ukrainian

Work with experimental data

• Visualisation: presents the measured values as graphs and tables
• Analysis: analyses the results obtained in the experiment
• Patterns: identifies the relationships observed during the experiment
• Reference comparison: compares the measured data with reference values
• Interpretation: helps students form hypotheses, conclusions and interpretations within a defined 'knowledge corridor'

Development of key skills

Work with the platform develops attention, logical and imaginative thinking, creative abilities and collaboration skills. Students can complete assignments individually or in groups, building learning independence and interaction.
