This video is about interactions between nutritional deficiencies and infections in low-income settings. First, the typical diet in low-income countries, and the most common micronutrient deficiencies will be described, and basic concepts about the malnutrition-infection cycle will be introduced. Then the role of iron, zinc and vitamin A in relation to childhood infections will be discussed. Finally, students will hear about the need for nutritional support to patients with TB and HIV patients.

The number of refugees and IDPs are increasing from fragile situations around the world. Lack of protective community structures and poor reach of health systems to these people result in both groups facing a triple burden of disease: 1) communicable diseases due to e.g. poor housing and sanitary conditions, 2) NCDs, because of poor life style and refugees are today older, and 3) injury due to e.g. violence and poor working conditions.

This presentation provides an introduction to the innovative use of technology to improve maternal and child health in low and middle income countries. Two of the major challenges in relation to reproductive and child health is access to health services and the quality of services provided in the health system. In continuation of this we’ll look into how mobile phone interventions can strengthen access to and quality of life saving interventions particularly in the time surrounding the delivery when the woman and the newborns are most vulnerable.

This learning video addresses a particular problem of selection bias, a statistical bias in which there is an error in choosing the individuals or groups to make broader inferences. Rather than delve into this broad topic via formal statistics, we investigate how it may appear in our everyday lives, sometimes distorting our perceptions of people, places and events, unless we are careful. When people are picked at random from two groups of different sizes, most of those selected usually come from the bigger group. That means we will hear more about the experience of the bigger group than that of the smaller one. This isn't always a bad thing, but it isn't always a good thing either. Because big groups ''speak louder,'' we have to be careful when we write mathematical formulas about what happened in the two groups. We think about this issue in this video, with examples that involve theaters, buses, and lemons. The prerequisite for this video lesson is a familiarity with algebra. It will take about one hour to complete, and the only materials needed are a blackboard and chalk.

The aim of this video lesson is to teach students about the different topologies of computer networks and how they function. The approach that is used is highly correlated with common knowledge about weddings and the local Malay culture associated with weddings. Students should be able to relate the act of delivering food to a large crowd of people to the basic principles of network topologies and the method of data transfer within each type of topology. The lesson will begin in a classroom with students working in small groups, answering assigned questions. Teaching aids such as color cards will be used. One student from each group will be appointed as the wedding event manager, and she/he will have to discuss and act out with group members in order to answer more challenging questions. At the end of the lesson, students will be asked to come up with their own version of a hybrid computer network topology. The lesson concept taught here not only educates students on computer topologies, but also introduces students to an important cultural perspective of Malaysia. Above all, this video is designed to assist students with their study of Computer Literacy in schools. The lesson will take up to 60 minutes to complete. Materials needed include: 10 red cards representing waitresses; 10 green cards representing waiters; 10 blue cards representing tables in the hall; a sketch book; and classroom tables and chairs.

This lesson uses the fundamentals of protein synthesis as a context for investigating the closest living relative to Tyrannosaurus rex and evaluating whether or not paleontologist and dinosaur expert, Jack Horner, will be able to "create" live dinosaurs in the lab. The first objective is for students to be able to access and properly utilize the NIH's protein sequence database to perform a BLAST, using biochemical evidence to determine T rex's closest living relative. The second objective is for students to be able to explain and evaluate Jack Horner's plans for creating live dinosaurs in the lab. The main prerequisite for the lesson is a basic understanding of protein synthesis, or the flow of information in the cell from DNA to RNA during transcription and then from RNA to protein during translation

This lesson presents the basics of aerodynamics by using kite flying as an example, i.e., forces acting on a flying object. Students will measure the net force acting on a kite due to blowing air and will learn how a simple instrument like a spring can be used to measure such force. They will also examine and experience how the force on the kite is transferred to the string in the form of tension and will again measure that tension with a simple spring. This lesson will take about 30 minutes to complete. One will need a calibrated spring to measure forces, as well as a few springs to study the coplanar forces.

This art history video discussion examines Leonardo da Vinci's "The Virgin and Child with St Anne and St John the Baptist" (Burlington House Cartoon), 1499-1500, charcoal and chalk on paper, c. 1499-1500 (National Gallery, London).

This website aims to teach the basics of Arabic to enabler users to read the Qur'an. The website breaks down YouTube video lectures into six levels of lessons, starting with the Arabic alphabet and working up through more complicated rules of recitation. Lessons also include letters that can be clicked on to see how they are drawn and word combinations with audio components so learners can hear how they are properly pronounced. The lessons are available for download, as are several PDF files relating to the study of the Qur'an.
