Lesson studyLesson study (or jugyō kenkyū) is a teaching improvement process that has origins in Japanese elementary education, where it is a widespread professional development practice. Working in a small group, teachers collaborate with one another, meeting to discuss learning goals, planning an actual classroom lesson (called a "research lesson"), observing how their ideas work in a live lessons with students, and then reporting on the results so that other teachers can benefit from it.
Nine Lessons and CarolsNine Lessons and Carols, also known as the Festival of Nine Lessons and Carols and Service of Nine Lessons and Carols, is a service of Christian worship traditionally celebrated on or near Christmas Eve. The story of the fall of humanity, the promise of the Messiah, and the birth of Jesus is told in nine short Bible readings or lessons from Genesis, the prophetic books and the Gospels, interspersed with the singing of Christmas carols, hymns and choir anthems.
Bending momentIn solid mechanics, a bending moment is the reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend. The most common or simplest structural element subjected to bending moments is the beam. The diagram shows a beam which is simply supported (free to rotate and therefore lacking bending moments) at both ends; the ends can only react to the shear loads. Other beams can have both ends fixed (known as encastre beam); therefore each end support has both bending moments and shear reaction loads.
A Lesson in RomanticsA Lesson in Romantics is the debut studio album by American rock band Mayday Parade. The band resulted from a merger of two separate bands, Kid Named Chicago and Defining Moment. In June 2006 the band released an EP, Tales Told by Dead Friends, which they sold to people by following the 2006 edition of Warped Tour and offering copies; it eventually sold 10,000 copies. The band signed to Fearless Records in August. A Lesson in Romantics was recorded in early 2007 with producers Zack Odom and Kenneth Mount.
BendingIn applied mechanics, bending (also known as flexure) characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element. The structural element is assumed to be such that at least one of its dimensions is a small fraction, typically 1/10 or less, of the other two. When the length is considerably longer than the width and the thickness, the element is called a beam.
Economics in One LessonEconomics in One Lesson is an introduction to economics written by Henry Hazlitt and first published in 1946. It is based on Frédéric Bastiat's essay Ce qu'on voit et ce qu'on ne voit pas (English: "What is Seen and What is Not Seen"). The "One Lesson" is stated in Part One of the book: "The art of economics consists in looking not merely at the immediate but at the longer effects of any act or policy; it consists in tracing the consequences of that policy not merely for one group but for all groups.
Swimming lessonsSwimming lessons are the process of learning to swim. In most countries there is a definition of a number of swimming levels that are reached in the process of the curriculum. The respective certificates of swimming tests are required for further training in aquatic abilities. Many countries have defined a minimum swimming level that children should reach by the end of primary education, in most cases with the help of school swimming classes being part of the normal curriculum.
Reinforced concreteReinforced concrete, also called ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials.
Sabbath SchoolSabbath School is a function of the Seventh-day Adventist Church, Seventh Day Baptist, Church of God (Seventh-Day), some other sabbatarian denominations, usually comprising a song service and Bible study lesson on the Sabbath. It is usually held before the church service on Saturday morning, but this may vary. It includes programs that are Bible based, to foster Christian growth. This period usually lasts for a period of 1 hour 40 minutes. During this time the "lesson study" is also conducted.
BabbelBabbel GmbH, operating as Babbel, is a German subscription-based language learning software and e-learning platform, available in various languages since January 2008. Babbel is operated by Babbel GmbH in Berlin, Germany. Babbel has around 450 full-time employees and freelancers. The company is based in the Berlin neighborhood of Mitte. The company was founded in August 2007 by Thomas Holl, Toine Diepstraten, Lorenz Heine and Markus Witte. In January 2008, the language learning platform went online with community features as a free beta version.
Shear and moment diagramShear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam. These diagrams can be used to easily determine the type, size, and material of a member in a structure so that a given set of loads can be supported without structural failure.
