Transferable/Scientific Skills Developed
Knowing how to recognize the fundamental importance of bone marrow functions and knowing how to connect certain blood diseases to its malfunction

Description
General aims
The purpose of the teaching unit is to bring students closer to the world of research and to stimulate critical and aware attitudes in them. The entire unit wants to provide an overview of stem cells and their use in the therapeutic field. This resource addresses, in particular, the study of the bone marrow and highlights its importance for hematopoiesis.

Linguistic aims
• Improving language skills in L2
• Enriching scientific vocabulary
• Knowing how to move from one linguistic register to another
• Producing clear and coherent texts in L2
• Summarizing written texts
Subject specific aims
This resource aims to make student understand:
• the structure of the bone marrow;
• the structural and functional difference between red and yellow marrow;
• the meaning of hematopoiesis;
• the differences between myeloid stem cells and lymphoid stem cells;
• how the onset of some blood diseases, for example leukemia, are due to the malfunction of this organ

Target group age
14-15

Level of competence in English (CEFR)
B1

Time required to use the resource with the students
3h 2h resource analysis
1h comparison and discussion
How to use it
The teacher briefly describes the topic highlighting the importance of the bone marrow for the production of blood cells and for immunopoiesis.To facilitate understanding of the text the passage is divided into short paragraphs that students must summarize and schematize. Various exercises are then proposed which can be questionnaires with true / false answer, multiple choice, open-ended questions, answer questions, complete sentences, associate terms, keywords, use of certain words to compose sentences. The class is then divided into small groups and each one is assigned a topic of the resource that must be studied in depth with personal research that can also include videos or animations of the topic, this to enhance listening skills. The work carried out will then be included in the final one which will concern the entire learning unit. It can be produced in Power Point, through video, audio interviews, animations, in this way digital skills are further favored.
The work will be presented to different classes

Possible difficulties for the students
Some difficulties can be given by the classification and functions of the various blood cells

Comments
Strength/Weakness Overall, the resource provides a good overview of the topic. It lends itself to be studied in various segments and this favors the acquisition of concepts and the work of the students. Scientific reliability From their website: “ThoughtCo is a primary reference site with a focus of over 20 years on educational content created by experts. We are proud to be one of the top 10 information sites, as measured by comScore, a leading Internet information company. In 2018 ThoughtCo received a Commuynicator award in the General Education category and Davey award in the Education category. " The rating of Media bias / fact check in is very high The author of the article is Regina Bailey: Biology Expert B.A., Biology, Emory University A.S., Nursing, Chattahoochee Technical College She is a registered nurse, scientific writer and certified educator. Her work has been featured in "Kaplan AP Biology" and "Internet for Cellular and Molecular Biologists". The contents of this resource are, however, easily verifiable Pedagogical value (e.g. collaborative learning, self–directed learning, peer assisted learning, etc) The methodology used for this resource is mainly Cooperative Learning. It takes place working together, through mutual help which also promotes socialization. The linguistic competence of everyone is a valid mutual support for all students. Researches shows this methodology is very effective, allowing students to achieve prefixed goals, stimulating their potentialities and critical capacities, leading them to better self-confidence and helping them to overcome stress and anxiety.
