The ALOP Workshop includes 6 modules:
MODULE I: Geometrical Optics: Rectilinear Propagation of Light, Reflection and Refraction
To discover how the light is diffused from a natural source
To quantitatively examine how the light intensity varies with the distance from a point source
To discover how the light rays can be used to represent how light is diffused from a point source
To discover the origin of parallel light rays
To qualitatively observe the interaction of light with surfaces of transparent objects
To qualitatively examine light reflection in a surface between two transparent materials
To understand reflection’s law
To understand Snell’s law of refraction
To observe the total internal reflection and discover under which conditions it happens
To examine the light dispersion and how a rainbow is formed
To explore how lens form images
MODULE II: Lens and Eye’s Optic
To learn the differences between images formed by positive and negative spherical lens

To observe and explain the behavior of light when a light wave from coherent sources are superposed (interference)
To observe and explain the behavior of light when it interacts with material obstacles (diffraction)

MODULE IV: Atmospheric Optics
To demonstrate simple and multiple dispersion
To show effects of dispersion in the intensity of transmitted light
To demonstrate the difference between absorption and dispersion in terms of the intensity of transmitted light
To show – by analogy – that multiple dispersion is responsible of the white color in clouds and the foam that is produced when water waves hit a beach
To show – by analogy – that the dispersion of particles and molecules in the air cause a visible haze that reduces the contrast between the shiny sky and the mountains in the horizon
MODULE V: Optical Data Transmission
To explore how information can be transmitted from a transmitter to a receiver
To explore how information can be transmitted using light
To design a simple optical source (LED and laser diode) and optical detector circuits (phototransistor)
To show the optical modulation (i.e. the conversion of an electronic signal in an equivalent optical signal, and then how to convert the optical signal back into an electronic signal)
To introduce the concept of information codification
MODULE VI: Wavelength Division Multiplexing (WDM)
To explore the factors limiting transmission rate or speed between transmitter and receiver
To explore the way to increase the quantity of transmitted information through fiber optic
To explore the dispersion of light

To demonstrate the WDM
To explore practical WDM systems
CERTIFICATES – EXPERIMENTATION KITS

10 experimentation kits will be donated to the institutions of the participants
THE TEAM OF UNESCO FACILITATORS
Prof. Angela GUZMAN
Physics Department, Florida Atlantic University, Boca Raton, USA.
Angela M. Guzmán joined the Physics Department of Florida Atlantic University in 2007. She is Professor Emeritus of the National University of Colombia, where she obtained her B. Sc. and M. Sc. degrees in Physics, and worked for over 25 years. She obtained her Ph.D. degree from the Ludwig Maximilian University in Munich for research conducted at the Max Planck Institute for Quantum Optics in Garching, Germany, and did her post-doctoral work at the Optical Sciences Center of the University of Arizona, Tucson, Arizona, USA. In 1988, as a young scientist, she was awarded the Colombian “Third World Academy of Science” Prize. In 1989 she was appointed Regular Associate Member of the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy. She is the recipient of the 1992-93 “Sarwar Razmi” Prize of the ICTP. In 1998 she was elected a member of the Colombian Academy of Science, and became Senior Associate of the ICTP. Currently she chairs the Advisory Group for the Trieste System on Optical Sciences and Applications (TSOSA). Prof. Guzmán Chaired the International Council of the Optical Society of America (OSA) and served as a Member of that Society’s Board of Directors during the period 2003-2004. From 2005 to 2008 she served as a Vice President of the International Commission for Optics (ICO) and Member of the ICO Bureau. In 2007 she was made an OSA Fellow for her contributions to quantum and atom optics and to the promotion of optics in developing countries. She was the ICO Secretary General until 2011; a part of her duties is to serve as the editor of the ICO Newsletter.
She attended her first ALOP Workshop in 2007, served as assistant facilitator in 2009 for ALOP-Bogota and as director of ALOP-Chile. She is in charge of coordinating ALOP Workshops in Latin America.
Prof. David R. SOKOLOFF
Department of Physics, University of Oregon, Eugene, USA
David Sokoloff is Professor of Physics at the University of Oregon. He earned his BA in Physics at Queens College of the City University of New York in 1966, and his Ph.D. in AMO Physics at the Massachusetts Institute of Technology in 1972 under Ali Javan. For over two decades, he has studied students’ conceptual understandings, and developed active learning approaches (with NSF and U.S. Department of Education, FIPSE support) including the four modules of RealTime Physics: Active Learning Laboratories (RTP) and Interactive Lecture Demonstrations (ILDs), (both developed with Ronald Thornton and Priscilla Laws and published by John Wiley and Sons). He has conducted numerous international, national and local institutes and workshops to disseminate these active learning approaches. Since 1999, he has been part of a UNESCO team presenting active learning workshops in developing countries, such as Active Learning in Optics and Photonics.. He is the editor of the Training Manual for the ALOP workshop that has been presented in Ghana, Tunisia, Morocco, India, Tanzania, Brazil, Mexico, Zambia, Cameroon, Colombia and Chile. The American Physical Society awarded him its 2010 Excellence in Physics Education Award (with Priscilla Laws and Ronald Thornton), and the American Association of Physics Teachers (AAPT) awarded him the 2007 Robert A. Millikan award for “notable and creative contributions to the teaching of physics.” He is currently the AAPT President Elect.
