Here are the best free Data Structures and Algorithms courses for Beginners to Join online: Table of Contents Data Structure and Algorithm is one of the essential topics for programmers, both to get a job and do well on Job. Good knowledge of data structure and algorithm is the foundation of writing good code. If you are familiar with essential data structures like an array, string, linked list, tree, map, and advanced data structure like Tries, AVL trees, etc and know when to use which data structure and compute the CPU and memory cost of your code in terms Even though you don't need to write your own array, linked list or hash table, given every major programming SKD provides them like JDK or C++ STL library, you will need to understand them so that you can use them in right place. Using the right data structure can drastically improve the performance of an algorithm. Ideally, we should all learn the data structure and algorithm in our school and college but it mostly didn't happen. Most of the programmers, including myself, only get introduced to a data structure in our computer science courses but we didn't really learn the real-world importance of them and that's why we didn't understand them better. For us, they are just the algorithms and data structure like some concept, not a tool which you can use to write good programs like we didn't know that Facebook would use them to store our details or Google will use them to store web pages and linked to search queries. Anyway, it's never too late. If you think that your data structure knowledge is not at par or you want to improve your data structure knowledge then you have come to the right place. Earlier, I have shared some of the free books to learn data structure and algorithms and in this article, you will learn about some of the best data structure and algorithm courses that are available for free online. Btw, if you can spend some bucks to learn valuable skills like Data Structure and Algorithms then I highly recommend you to join Data Structures and Algorithms: Deep Dive Using Java course by Tim Buchalaka on Udemy.

Remember when students would fill out their information on index cards? Thank goodness all that stuff is now in our computer data bases! But having easier record keeping meant I missed out on the opportunity for my students to provide information I needed in order to get to know them. Knowing your students well is such a vital part of building a classroom community. It helps with management, motivation, and shows your students that you really care about them as people. There's no better way to get to know a shy student than to ask him or her about something you already know they are interested in. This year why not ask your students to tell you about themselves in a really cool and timely way. Everybody's tweeting! Why not take advantage of the familiar format of hashtags, tweets and trends to get a glimpse at your students' interests and goals. I have used a sheet like this one with a lot of success in the past and I love to see the students react when they see that I'm not as un-cool as they might be expecting! Please leave feedback!

Are you in the middle of #dataoverwhelm? Data collection is hard. How do special education teachers juggle it all and still keep their students engaged?

Collecting data on the IEP goals...(even and especially the ones you didn't even write) can be annoying, difficult, a lot of work, is just what us special education teachers gotta do... I recently had a question about what kinds of forms I keep on my clipboards so I snapped a couple of pictures. Mostly, I have data sheets to collect data on IEP goals. And also a few behavior data sheets.
