  1. LEARNING OUTCOMES
Learning Outcomes
Please describe the learning outcomes of the course: Knowledge, skills and abilities acquired after the successful completion of the course.
The course material aims to teach students the structure of wood, its chemical composition and the chemical composition of bark and foliage. Also in learning the distribution of chemical components in cell walls. As well as learning the structural components of the cell wall (cellulose, hemicellulose, and lignin) as well as the extracts. Also in learning the chemical properties of wood, the chemical utilization of wood, the chemical products of wood

Upon successful completion of the course the student will be able to:

• recognize the chemical composition and analysis of tree bark and foliage, the distribution of chemical components in cell walls, the properties of wood chemicals, the chemical properties and chemical behavior of wood as a solid material and finally the various chemicals produced or can be produced from wood

• apply laboratory experiments to determine extracts, lignin, whole cellulose, hemicelluloses

ANNEX OF THE COURSE OUTLINE

 

Alternative ways of examining a course in emergency situations

 

Teacher (full name): Vasiliki Dimou
Contact details: eclass, email
Supervisors: (1)  
Evaluation methods: (2) Written examination by remote methods, provided that the integrity and reliability of the examination is ensured
Implementation Instructions: (3) The examination of the course will be carried out through eclass according to the examination program. Students who have institutional accounts, have registered for the course and have learned the terms of distance education can take part. Students after their composition in eclass will randomly receive, from a question pool, 20 questions that you must answer in 15 minutes. Each of the questions will be graded 0.5.

The examination of the laboratory part of the course will be carried out in eclass medium according to the examination program. Students who have institutional accounts, have registered for the course and have learned the terms of distance education can take part. Students after their composition in eclass will randomly receive, from a question pool, 10 questions that you must answer in 10 minutes. Each of the questions will be graded with 1.0
