The purpose of the entry event is to engage students' curiosity and motivation, and to provide context and background information about the project.
7. In a PBL project, a student could play the role of a researcher, designer, developer, or project manager, among others.
8. The entry event is an important part of the PBL process because it sets the stage for the rest of the project and helps students understand what they will be working on and why it is important. It also helps students identify the knowledge and skills they will need to complete the project successfully.
11. Need-to-know-questions are questions that students need to answer in order to complete the PBL project successfully. These questions should be related to the project challenge or problem, and should be specific and focused.
13. The driving question is a central question that guides the PBL project and helps students focus their learning and problem-solving efforts. The driving question can be found in the entry event and in the project's final product or presentation.
14. Benchmarks are specific, measurable goals that students should aim to achieve as they work on the PBL project. They are used to track progress and ensure that students are on track to complete the project successfully.
16.. Examples of final PBL projects might include a prototype of a new product, a business plan, or a marketing campaign.
17. PBL projects are typically graded based on the quality and completeness of the final product or presentation, as well as the student's effort and progress throughout the project.
18. The three parts of the PBL Project Rubric are content, process, and product. The content refers to the knowledge and skills that students demonstrate in the project, the process refers to the steps they took to complete the project, and the product refers to the final product or presentation.
19. Two success skills might be problem-solving and collaboration.
20. Sharing what you've learned is an important piece of the PBL process because it allows you to reflect on your learning and demonstrate your understanding to others. It also provides an opportunity for feedback and further learning.
21. The ability to analyze your work is an important piece of the PBL process because it helps you to reflect on your learning and understand what you have accomplished and what you still need to work on. By analyzing your work, you can identify your strengths and weaknesses, and make adjustments as needed to improve the quality of your final product or presentation.
22. Tallo is a career and educational platform that connects students with opportunities and resources related to their interests and goals.

What are Python's fundamental concepts?Similar to the English language, Python has a straightforward syntax. Python features a syntax that makes it possible for programmers to write programs with less lines of code than with some other programming languages.Code written in Python can be executed immediately since it runs on an interpreter system. Prototyping can therefore be completed relatively quickly.The Python programming language was created by Guido van Rossum and is an interpreted, object-oriented, high-level language with dynamic semantics. In 1991, it first became available. The name "Python" is a play on the British comedy troupe Monty Python and is meant to be both simple and entertaining.Unlike actual programs, which are constrained by the syntax of a programming language, algorithms serve as prototypes for them.To learn more about Python refer to:

write a complete program to do the following: the main program calls a method to read in (from an input file) a set of people's three-digit id numbers and their donations to a charity (hint: use parallel arrays). then the main program calls a method to sort the id numbers into descending order, being sure to carry along the corresponding donations. the main program then calls a method to print the sorted lists in tabular form, giving both id numbers and donations. here are the details: (a) the main program calls a method to read in the data from a file. the main program declars two arrays idnumbers and donations and pass these 2 array to the method to fill in. the file consists of sets of data, each of which contains a person's three-digit integer id number and a donation in dollars and cents. (e.g., 456 200.00 or 123 302.34). the file is read until end-of-file is reached. the method returns how many sets of data were read in. the main program calls the return value donorcount. (b) the main program calls a separate printing method passing the two original arrays idnumbers and donations as parameters. the method prints the original set of data in the form of a neat table and sends the output to an output file. when the arrays print, there should be an overall heading, plus headings for the columns of id numbers and donations. (c)then the main program sends the array of donation to a method which is going to find out the highest, and the lowest donation. this method opens the same file as in part (b) and writes how many donations are above, below, and exactly equal to the average. (d) then the main program sends the array of id numbers, the array of donations, and the size donorcount to a sorting method. this method sorts the id numbers into numerical order using a selectionsort. be sure to maintain the match-up of id numbers and donations. for example, 456 should always be associated with 200.00, no matter where 456 moves in numerical order; similarly, 123 should stay with 302.34. then the sorting method prints two highest donations, and two lowest donations. when the sorting method finishes and returns control to the main program, the main program calls the printing method to write the sorted table once again in the same output file as in part (b). your arrays should have room for up to 50 entries. to test the program, have a set of data with at least 15 to 20 values in each array. make sure that your original order in not close to numerical order for either array or that the two numerical orders are not close to each othe
