Learning objectives
Objective of the teaching is to provide a general framework of the History of Chemistry from its origins to the beginning of the 20th century, outlining the main themes and conceptual acquisitions that have characterised its evolution, with particular attention to the Periodic Table of Elements. The assumptions of the development of scientific thought, the historical and cultural context in which Chemistry developed and the effects that this evolution had on society and the environment, especially after the emergence of the first inorganic industrial processes, will be illustrated. A section will be dedicated to illustrate the main methods and tools of chemical didactics, aimed at the acquisition of fundamental competences for the design of effective teaching paths. This will be followed by exercises with applied examples of the teaching methods learnt.
Expected learning outcomes
At the end of the learning process, the student will be able to historically frame the fundamental discoveries of Chemistry from its origins to the beginning of the 20th century, describe its evolution in relation to the historical and cultural context and explain its impact on society and the environment. In addition, the student will learn and be able to apply the main methods and tools of chemistry didactics aimed at the acquisition of fundamental competences for the design of effective teaching paths.

6 CFU = 56h (5 CFU = 48h + 1 CFU 8h)
1. The origins of chemistry: protochemistry, alchemy and iatrochemistry
The beginnings of chemistry; Greco-Alexandrian alchemy; Chinese alchemy; alchemy in the Islamic world; alchemy in Western Europe; Paracelsus and iatrochemistry; the birth of phlogiston.
2. The scientific method, pneumatic chemistry, the Age of Enlightenment, the birth of the new chemistry
The scientific method; early pneumatic chemists; the discovery of oxygen, nitrogen and hydrogen; the Enlightenment and the end of phlogiston; Lavoisier's revolution, its condemnation and legacy; the birth of the new chemistry in Europe and Russia.
3. Atoms and the theories of matter.
Chemical affinity; stoichiometry and chemical equivalents; the law of definite and multiple proportions; Dalton and his atomic theory; the law of volume combination by Gay-Lussac; Dalton's supporters and opponents; Prout and primal matter; Berzelius and the theory of dualism; Faraday: a chemist lent to physics.
4. Atomic and molecular weights
Avogadro and the modern concept of a molecule; Cannizzaro and the Karlsruhe Congress.
5. The language of chemistry
The birth of chemical nomenclature.
6. The separation of the inorganic and organic worlds.
Vitalism. The development of elementary analysis; Berzelius and the theory of radicals.
The birth and development of the concept of valence.
From valence theory to coordination chemistry.
7. The periodic system of the elements.
Early ideas of periodicity; Mendeleev and the periodic system; Lothar-Meyer: confirmation of periodicity; some 'minor' scholars who contributed to the birth and development of the periodic table; from atomic weight to atomic number; Curie and radioactivity; transmutation of the elements; transuranic elements and the development of the periodic table.
9. Early inorganic industrial processes.
The ammonia industry (Haber-Bosch process) and the controversial figure of Fritz Haber.
10. Fundamentals of Chemistry Didactics:
o Planning a lecture: the importance of aligning with course objectives and assessment mode; key features of a lesson plan; proper use of technology in the planning the activities; and the importance of testing knowledge and learning before, during, and after the course.
o Lecturing a class: balancing lecture materials (e.g., slides); the importance of verbal and nonverbal communication; strategies to engage and motivate students; the importance of soliciting/receiving questions and providing accurate answers in class.
o Strategies for engaging and motivating students during a lecture: plainly state the relevance of teaching content in the context of the education process and for the future professional career; building and maintaining a positive learning environment; the key role of interacting with students and the different types of questions which can be used; the relevance of different types of communication (verbal, nonverbal and para-verbal) implemented by the lecturer when answering.
o Teaching approaches and their use in the classroom: teacher-centered, learner-centered, and action-centered approaches; the main characteristics of a "transmissive" lesson and strategies to make it effective; examples of teaching techniques: "Team-Based Learning", "Flipped classroom" and "Think, Pair, Share".
Prerequisites for admission
The student must possess the basic knowledge of general chemistry acquired in the General Inorganic Chemistry course of study.
Teaching methods
The lectures are held in the classroom with the projection of 'slides' in power point format and in-depth video documentaries, with the use of some innovative didactic tools such as the Wooclap digital student engagement platform. Students have access to the professor's Ariel website, where various teaching materials, including lecture slides, are regularly posted.
Teaching Resources
Lecture slides, video-documentaries and in-depth material on the professor's Ariel website.

Assessment methods and Criteria
The examination consists of a written test and an oral test, the grade being expressed in thirtieths.
The written test (duration 1 hour) consists of 14 multiple-choice questions. The aim is to ascertain the student's knowledge of the syllabus. If the written test is passed with a mark of at least 18/30 (8 correct answers out of 14), the student may proceed to the oral test.
The oral test consists of a report on a topic of the student's choice. The file of the report will be sent to the professor no later than 1 week before the date of the oral examination and will be presented on the day of the exam as a power point presentation and/or video and/or podcast (duration of presentation about 15 minutes with discussion). The professor will assess the student's ability to explore the chosen topic in depth, framing it in its chronological and conceptual development with rigour and clarity of presentation. At least a mark of 18/30 is required to pass this test. The arithmetic mean of the marks of the two tests represents the final examination grade in thirtieths.
