Colin Powells Leadership Presentation297MCPennyfather
This document contains 18 lessons on leadership from General Colin Powell. Some of the key points covered in the lessons include: being responsible means making difficult decisions that will upset some people; leaders must be accessible and address their employees' challenges; leaders should not be afraid to challenge experts or conform to stereotypes; and effective leadership relies on attracting talented people and keeping them motivated.
The document summarizes the Texas STaR Chart, a tool used to evaluate schools' progress in technology integration. It provides an overview of the chart's key areas and levels of progress. For Smithson Valley High School, it finds they are currently at the "Developing Tech" level for Educator Preparation and Development. It analyzes their goals and benchmarks to advance to the "Advanced Tech" level within two years by improving staff training through weekly learning sessions.

Technology Organizational Chart and Action Plandeanhofer
The document provides instructions for a Week 4 assignment in an educational leadership course focusing on instructional leadership and the integration of technology. Students are asked to develop an action plan with four components: 1) Identifying data sources; 2) An organizational chart of technology decision making; 3) A comprehensive professional development plan; and 4) An evaluation plan to assess progress. Students will post their action plans online and review another student's plan with a focus on organizational leadership and technology. The assignment is due by the end of Week 4 and will be evaluated based on a provided rubric.

This document appears to be discussing various symbols and sections. It contains symbols like §, , , and à repeated in various configurations with some text between symbols that is unclear. The document lacks context or identifiable meaning within 3 sentences.
1. This document is a portfolio submission sheet for an ITCE (Information Technology for Continuous Education) program submitted by Wong Hang Chi, a student in the PGDE(S) Mathematics program at HKIEd with a student number of 09451331 and expected graduation date of July 2010.
2. The sheet includes a declaration that the three required ITCE portfolio items have been completed at the Upper Intermediate Level, including a project-based learning proposal, reflection on changes to teaching philosophy/subject due to IT, and a conclusion on the pros and cons of integrating ICT in education in Hong Kong.
3. Wong Hang Chi signs the sheet to declare the work as his own and the instructor,
1) ICT tools can enhance the effectiveness of teaching by allowing teachers to demonstrate concepts like graphs and functions in new ways. However, it also increases the pressure on teachers who must acquire new skills and ensure appropriate use of technologies.
2) While ICT helps students learn independently, it risks exacerbating inequality if not all students have equal access. Weaker students especially benefit from tools like graphing calculators, but quality of access may differ by individual backgrounds.
3) Schools must be aware of both the advantages of ICT in modernizing education, as well as the disadvantages like potential increases in differences between strong and weak students due to unequal access, in order to develop policies that mitigate risks.
The document discusses two approaches to teaching students about the area of a circle - using ICT tools or a traditional non-ICT method. Using ICT tools like Mathematica Player allows the teacher to demonstrate incrementally increasing the number of sectors in a circle to show the limiting case of a rectangle, which helps students understand that the area is πr2. The traditional method involves students physically cutting a paper circle into sectors but is more time consuming and limited. While ICT tools save time and help demonstrate the limiting concept, the traditional approach allows students to physically manipulate the materials.
The document proposes a project-based learning activity to teach students about Fermat's problem for Torricelli. Students will form groups and use dynamic geometry software to investigate Viviani's theorem. They will then perform an experiment involving drilling holes in acrylic boards and attaching strings to masses to measure angles. Finally, students will research the Fermat point online and present their findings to the class. The teacher's role is to facilitate learning through questioning rather than simply providing answers. ICT tools like dynamic geometry software and videos are used to enhance collaboration and make the activities more interactive.
This document discusses logical reasoning and provides 3 examples of problems solved through logical reasoning. Logical reasoning involves breaking down problems into logical steps and using techniques like deduction and contradiction to arrive at solutions. The first example asks if 44 silver dollars can be distributed into 10 pockets with each pocket containing a different number of dollars. The second example asks if a notched checkerboard with squares removed can still be covered with the remaining dominoes. The third example asks if the equation x2 + y2 = 3(u2 + v2) has any integral solutions other than (0, 0, 0, 0). The document concludes by listing references on problem solving strategies and mathematical methods.
1. The document discusses the "pizza problem" of dividing a circle into slices using chords and determining if the black and white areas are equal.
2. It introduces the Tiffany Lemma, which shows that the sum of the squares of the lengths of four chords through a point is a constant equal to 4 times the radius squared.
3. By using polar coordinates and the Tiffany Lemma, the solution shows that the integral of the black and white areas over any interval of length π/2 is π/2, proving the areas are equal.
The document discusses the trial scheme on school drug testing in Tai Po District from three sociological perspectives - structural functionalism, social conflict theory, and symbolic interactionism. From the structural functionalist view, the scheme aims to fulfill the social functions of the education system and narcotics division by deterring drug use and motivating abusers to seek help. However, it also creates social dysfunctions like increased public tension and labeling effects. The social conflict perspective sees the scheme as imposing government authority and creating social inequality between authorities and students. Finally, the symbolic interactionism perspective analyzes how the government constructs positive perceptions of the scheme through explanations, media coverage, and protecting students' self-concepts and esteem.
This document discusses a proof in geometry about angles in a triangle. It shows that the angle between a line parallel to one side of a triangle and another side is equal to the opposite angle in the triangle. It provides two steps to prove this using properties of parallel lines and the angle sum of a triangle being 180 degrees.
El documento presenta una demostración geométrica de que si AB = CD y AD//BC, entonces BD = CA. Primero establece que si AB = CD y AD//BC, entonces EBC ~ EAD y BE = CE. Luego, usando propiedades de triángulos similares y congruentes, deduce que BD = CA.
El documento describe un triángulo ABCD donde se dan los ángulos A = 63° y D = 117° y las longitudes BC = AD. Se deduce que la suma de los ángulos internos es 180° y que los lados AB y CD son paralelos, por lo que ABCD es un paralelogramo.
