In order to further enhance students' sense of quality and security and sense of responsibility for food security, and learn related knowledge of food and food inspection and testing, Dongyuan Middle School affiliated to Liaocheng No. 2 Middle School launched a project-based learning activity with the theme of "Food Security Responsibility is Me". Before departure, Principal Zhang Yang assigned a task

The students listened carefully

During the event, students from the Dongyuan of Tsinghua and Peking University first visited the grain and oil testing department and the food (agricultural products) testing department laboratory on site, felt the inspection and testing work environment, understood various inspection and testing instruments, and had in-depth understanding of the inspection and testing related work processes, and had on-site communication and interaction. The teachers of the Inspection and Testing Center patiently answered the students' questions in the grain quality testing. After visiting the laboratory, according to the project-based learning design plan, the students "turned into" a food security "goalkeeper". Under the patient explanation and demonstration of the testing center teacher, some students selected wheat samples from the operating table into "impurities, gibberellum, baked grains, frostbite grains, and sprouted grains" on the operating table, and completed the calculation of the imperfect particle value of the sample according to the national standard testing method; some students operated the precision analysis balance, pipette gun , gluten washing machine, centrifuge , dryer and other equipment, studied the national standard testing method of wet gluten, and calculated the wet gluten value and moisture content of wheat flour... The students gained a lot from intense discussions, hands-on operations, and rigorous calculations, and more fully understood the responsibilities and responsibilities of the grain inspector teacher.

Hands-on recognition

Immersive situational scientific problems, knowledge, and technology experience, a large number of hands-on practical operation opportunities, scientific top-level design and careful guidance of project-based learning teachers, collaborative exploration by students, and achievement of works (or products) that are not limited to form, all demonstrate the richness and colorfulness of this project-based learning activity. The person in charge of Dongyuan Middle School affiliated to Liaocheng No. 2 Middle School said that in the future education and teaching, our school will closely follow the requirements of the new curriculum standards, and take this as an opportunity to create better learning opportunities and knowledge experience platforms for Dongyuan students.
