At the moment there is a focus on the use of the Ministry’s equipment. To this end, cables are being created with which sensors can work with as many boards as possible, the STEM Extension with which we can program S1 & S2 with Mind+, Lego type building materials, Supporting materials with related lessons and books and suggestions. Seminars have been started to make use of the equipment available in schools.

The preparation of the Panhellenic Competition is in progress, for which the registration form for teams, information, the webinars for teachers’ preparation, etc. can be found here.

We can design our own knowledge and skills path.

Starting from what I am and where I want to go, we end up going through similar educational material, which is available in the [Repository] and in the [Repository structure] that is organised to facilitate this journey.

What is STEM

An attempt to clarify the term and the approach
through relevant examples of scalar complexity.

It refers to approaches to education that integrate all four domains interdependently: Science, Technology, Engineering and Mathematics, encouraging interdisciplinary learning, critical thinking and problem solving.

What is STEM

STEM (Science, Technology, Engineering, Mathematics) refers to an interdisciplinary approach to education that integrates science, technology, engineering and mathematics. The aim of this approach is to provide authentic learning experiences that link theory to practice (stemedresearch.siu.edu)

From a pedagogical point of view, it promotes learning through the discovery and solution of real problems. This is achieved through the use of engineering design, where students are asked to define problems, develop and test solutions, thus enhancing their understanding and application of their knowledge to real-life scenarios (doe.virginia.gov).

The integration of mathematics and other sciences is seen as critical to the quality of STEM curricula. However, studies have shown that effective integration of these elements can be challenging, indicating the need for ongoing professional development for teachers and careful curriculum design (docs.lib.purdue.edu).

According to the guidelines of international organisations such as theNext GenerationScience Standards(NGSS, 2013) and UNESCO (2021), STEM education aims to develop critical thinking, creativity and problem-solving skills through experiential and inquiry-based learning.

STEM education is based on the principle of constructivist learning, where students build knowledge through active engagement in experimental activities. The interdisciplinary approach allows students to develop skills related to computational thinking, mathematical modelling and designing technological solutions. Research shows that participation in STEM activities increases students’ engagement with science and technology, preparing them for the demands of modern society(Bybee, 2013).

After completing the activity, students will have an understanding of basic meteorological parameters, such as temperature, humidity, wind and precipitation, and will be able to analyse sensor data, applying physics and mathematics principles. They will construct and calibrate a weather station, programming data collection and analysis with visualized interfaces.

At the same time, they will develop scientific thinking skills, collaboration and environmental sensitivity, by linking their measurements to real data and investigating the impact of meteorological phenomena on the environment.

General examples of STEM activities

Example 1: Investigating engineering structures

An introductory STEM activity might involve designing and building bridges using simple materials such as cardboard and sticks. Students work together to create models that can withstand different loads, applying engineering and physics principles. This activity promotes collaboration, computational thinking and the ability to analyse data.

Example 2: Programming and automation

Students use programming platforms, such as Scratch or Mind+, to create microcontroller-based automation (e.g. Arduino, micro:bit). Through exploratory learning, students develop algorithmic thinking skills and understand the importance of sensors and data in automation.

Learning outcomes

Based on the Curriculum, STEM activities should incorporate objectives that include:

  • Understanding basic scientific principles through experimentation and simulations.

  • The development of modelling and problem-solving skills.

  • Familiarity with programming and the use of technological tools.

  • Promoting teamwork and communication through collaborative activities.

More examples of STEM activities

Example 3: The construction of a simple solar oven from recyclable materials

Students will learn about physics (heat and energy), engineering (design and construction), mathematics (calculations of dimensions and angles) and technology (use of tools and materials). An activity that encourages combinatorial thinking, collaboration, experimentation, applying theoretical knowledge to practice, and searching for critical resources.

Example 4: Digital Temperature Meter

Another interdisciplinary example involving micro:bit automation is the construction of a “smart thermostat”. This activity combines elements from science, technology, engineering and mathematics, and can be linked to the education curriculum.

Students will use a microprocessor and two more IoT (temperature sensor and LEDs) to create a temperature gauge that will detect the temperature of a room and light different coloured LEDs (depending on the temperatures observed).

The “engagement” of the sciences:

  • Science: discuss the basic concepts of temperature, the Celsius and Fahrenheit scales, and how different factors affect the temperature in an environment.
  • Technology: we explore the operation of the microprocessor and the features it offers, such as temperature sensors and LEDs. Students will utilize programmable structures (conditions) and instructions and functions to read, display temperatures, and light LEDs under conditions.
  • Engineering: students design the automation layout and argue how to place it in a specific environment and with which construction, keeping in mind both the aesthetics and ergonomics of their construction.
  • Mathematics: we use mathematical equations to calculate the average temperature and see how the data varies over time. We create graphs to illustrate changes in temperature by period based on our measurements.

Link to the Curriculum:

This activity can be integrated into courses in Science (energy flows, thermodynamics), Technology (programming and robotics), and Mathematics (statistics and data analysis). At the same time, it encourages critical thinking, collaboration and an interdisciplinary approach. Students acquire practical knowledge and skills in an enjoyable and creative way, which will be useful in the future.

Evaluation in STEM education

Assessment is a fundamental element of the learning process as it allows for continuous monitoring of student progress and feedback to improve skills (Black & Wiliam, 1998). Particularly in STEM education, where skill development includes cognitive, practical and metacognitive dimensions, assessment needs to be multidimensional and based on a variety of strategies (Sadler, 1989).

Evaluation:

Assessment is a fundamental element of the learning process as it allows for continuous monitoring of student progress and feedback to improve skills(Black & Wiliam, 1998). Particularly in STEM education, where skill development includes cognitive, practical and metacognitive dimensions, assessment needs to be multidimensional and based on a variety of strategies(Sadler, 1989).

Dimensions of the Evaluation
  • Understanding basic concepts and applying them to real problems

    Students are assessed on their understanding of fundamental principles and their ability to apply them to authentic problems(Bransford, Brown, & Cocking, 2000).Assessment includes discussions, case study analysis and laboratory reports(Harlen, 2013).

  • Operation and programming of microprocessors and sensors

    Emphasis is placed on practical application through the creation of microprocessor-based systems, such as Arduino and micro:bit(Grover & Pea, 2013).Students are assessed by presenting projects, documenting their code and analysing the algorithmic structures they use(Linn et al., 2015).

  • Understanding of system design and manufacturing processes

    Mechanical thinking and problem-solving skills are key elements of STEM education(National Academy of Engineering, 2009).Assessment includes the creation of functional prototypes, analysis of design options, and teamwork(Kolodner et al., 2003).

  • Application of mathematical tools in data analysis

    Students are assessed on their use of statistical and mathematical tools to process data and create graphs(Tufte, 2001).An important element of assessment is the accuracy of calculations and clarity in the presentation of data(Wilks, 2019).

Evaluation strategies
  • Continuous assessment (Formative Assessment)

    Continuous monitoring and feedback improves the learning experience and enhances students’ self-regulation(Black & Wiliam, 2009).It includes observations, verbal questions and progress monitoring during activities(Sadler, 1989).

  • Portfolio-Based Assessment (PBA)

    The systematic collection of deliverables, such as assignments, programming projects, and data analyses, allows for the recording of students’ learning progress(Paulson, Paulson, & Meyer, 1991).
    Qualitative analysis of projects helps to identify strengths and weaknesses in learning(Shepard, 2000).

  • Peer Assessment (Peer Assessment)

    Peer assessment fosters collaboration and metacognitive thinking, helping students to understand quality criteria and develop feedback skills(Topping, 1998).Students are involved in evaluating their peers’ work using clear and structured criteria(Falchikov & Goldfinch, 2000).
