Cast iron with magnesium induced spheroidised graphite
Cast iron is a brittle material and it is advantageous to process it in such a way to improve its ductility. The brittleness is partially due to the graphite flakes which act as nucleation sites for cracks. Therefore it is an advantage to have the graphite present as spheres. This can be achieved by a heat treatment regime or by the addition of a small amount of Mg which poisons the graphite growth directions.
NASA CONNECT The Right Ratio of Rest: Proportional Reasoning
In the activity, The Right Ratio of Rest, students will collect and record data in a sleep journal about their sleeping habits for 5–7 days. They will analyze their data by using math skills to convert between fractions, decimals, and percentages and will create graphs and fraction wheels that correspond to their data. They will use proportional reasoning to determine amounts of sleep time that people need in space, given the different lengths of light-dark cycles for various planets. Grades 6
Improving Literary Understanding Through Classroom Conversation Booklet
Effective literature instruction develops reading, writing, thinking, and other literacy skills -- but that is easier said than done. A new booklet by Judith Langer and Elizabeth Close shares some of the most effective strategies, drawing on the research and including real classroom examples. The booklet is designed for teachers and administrators who wish to improve their students' reading comprehension
Factors influencing meaningful integration of technology into the high school curriculum: a case stu
Technology has significantly impacted American life. Children today grow up with a profusion of electronic wonders. Technology use in schools has lagged behind technological uses in society as a whole. As school districts strive to meet public expectations for technology use, school budgets devote significant dollars to technology related initiatives designed to improve student achievement. While money has been spent on technology, districts struggle to document improvement in student achievemen
Implications of resource management in La Parguera, Puerto Rico (The)
A recent rezoning of La Parguera, southwest Puerto Rico, as a tourist zone has resulted in an imbalance between development and appropriate resource management. Development associated with tourism is destroying the sub-tropical dry forest and adding pressure on the marine resources through increased boat traffic and marine structures. Declining water quality and benthic community health are two of the impacts seen in La Parguera associated with these land use changes. This study is three-fold. F
Patient Communication Skills, 2009
The materials on this page represent a curriculum for teaching effective patient communication to dentistry students. These techniques could be useful for other healthcare providers, as well: medical students, nursing students, public health providers, and in-practice health care providers. There are two main types of resources: performance keys and videos.
Performance Keys are text documents that articulate key patient interaction skills, and give examples of more and less effective techniques
Algebra IB
Welcome to the NROC Introductory Algebra course. This curriculum emphasizes a multi-representational approach to algebra, with concepts, results, and problems being expressed graphically, analytically, and verbally. It develops algebraic fluency by providing students with the skills needed to solve equations and perform important manipulations with numbers, variables, equations, and inequalities. In addition, the course develops proficiency with operations involving monomial and polynomial expre

DoHistory
This site invites you to explore the process of piecing together the lives of ordinary people in the past. It is an experimental, interactive case study based on the research that went into the book and film A Midwife’s Tale, both based upon the remarkable diary of 18th-century midwife/healer Martha Ballard. Although DoHistory is centered on the life of Martha Ballard, you can learn basic skills and techniques for interpreting fragments that survive from any period in history.
Learning Domains or Bloom's Taxonomy
This website provides an explanation of Bloom's Taxonomy for the three domains of learning: cognitive, affective, and psychomotor. The cognitive domain involves knowledge and the development of intellectual skills, the affective domain deals with emotion, and the psychomotor domain includes physical movement, coordination, and use of motor-skills. This site presents a compilation of Bloom's Taxonomy in a table that divides the three domains into subdivisions, going from the simplest learning beh
Private Universe Project in Mathematics: Workshop 5. Building on Useful Ideas
One of the strands of the Rutgers long-term study was to find out how useful ideas spread through a community of learners and evolve over time. Here, the focus is on the teacher’s role in fostering thoughtful mathematics.,Englewood—Kindergarten: Stacking Blocks In Englewood, New Jersey, a kindergarten teacher uses blocks as mathematical objects in an addition activity.

Technology and Society
Students of engineering and surveying need to understand and be convinced that through their future professional work they will relate to the rest of society. Throughout their careers they will need to strive to ensure that this relationship is meaningful and successful. Only then will they earn respect for themselves and their profession, and ensure their work will be valued and recognised. For engineers and surveyors to meet their responsibilities towards society they must be able to appreciat
Teaching Students with Special Needs: Behaviour Management
In this course students are introduced to a wide range of methods and strategies for meeting the needs of children with behavioural and adjustment problems in regular preschool, primary and secondary classrooms. The course explores research on teaching and defines what is currently known about how to effectively teach children with special needs with a particular emphasis on maintaining student attention and on-task behaviour. First, basic classroom teaching and management skills and procedures
Studying to Succeed: Planning your study program day by day
Students progress through a program which requires them to manage their own learning and establish their own future goals through a process of self development. Career planning is a key component of the program. Effective study skills and attitudes will be developed and applied to areas of communication studies to prepare the student for entry into a tertiary undergraduate course. The language content is provided in a broad context to best enable students to continue in the career of their choic
Money and Banking
The financial crisis of 2007-8 has already revolutionized institutions, markets, and regulation.
