Week 3: What I really want to teach?

-

 

I already knew a little bit about CSS which is related to styling of the website. However, I've never actually used CSS because I've never actually built a website. Before taking this class, I thought that building a website was just like making an app. It was the same in making the website according to the desired specification by coding it, and putting the desired function into the website to make it work. However, I found that the way of putting the styling and functions to the website was quite different from making a mobile app. It was really interesting to me. To develop a website, three programming language are needed, HTML, CSS, and JavaScript. It is the different point from mobile app development which needs only one programming language, such as objective C, Swift, Android Java, or Flutter. HTML is responsible for the layout of, CSS is for styling of, and JavaScript is in charge of functions of the website. Also, writing a code at any text editor is different from mobile app development which runs at the specific tool, such as iOS is with XCode. In this respect, it can be easy and convenient to start learning web development compared to app development. It can be expected that web development to be easy to the developer. However, the language systems are so different that it gets very confusing every time I code. Of course, the basic concept, writing code makes the product run, is same for both, so understanding how website works is not a problem. Learning a new development language is always challenging and also refreshing.


My original plan is to develop the instruction that teaches how to create educational mobile apps for people in education. After receiving feedback from Dr. Karlin, I got to know this is too long to make a 1-hour instruction. So, I had to redesign the instruction, and finally decided to teach the first part of making a mobile app for education, designing the mobile app. This is the most important step in app development to design the overall layout and interface. I'm trying to think from the perspective of people who don't know anything about app development. I considered carefully what I want the potential learners to do it after the planned instruction as Mager (1984) mentioned. I wanted that the learners will understand the given specification, design the layout and interface according the specification, and draw the design (it can be a mockup for coding). I planned four lessons for this instruction: 1) what a mobile app is, 2) overall process of developing a mobile app, 3) review the existing mobile app in education, and 4) design the quiz app according to the provided specification. The basic layout of each lesson is composed of three parts: 1) explaining the concept of the lesson, 2) demonstrating lesson concept, and 3) assess how much learners understand by assessment tools. I think three types of assessments for this lesson: 1) pop quiz, 2) critique of the existing mobile app, and 3) design project to design the mobile app. But I will improve the current plan according to the lesson I will take. 


Mager’s tips on instructional objectives helped me to better understand how to set the objectives of the intended instruction. Before taking this class, I thought abstractly about the purpose of instruction. I thought it was meant to gain new knowledge or acquire a skill. However, after reading Mager's explanation, I learned that the purpose of instruction is quite specific and clear. It is for changing the behavior of the learner or letting the learner to acquire and express new knowledge. That is, the focus of instruction is not on the process of delivering the instruction, but on the change that occurs in the learner after delivery of instruction. However, I think it is possible to quickly analyze the cause and find a way to solve the problem quickly when the desired result is not obtained by carefully observing the process of delivering the instruction. I strive to set a clear goal of the intended instruction and come up with a way to help potential learners take this instruction without problems or boredom.

ITEC830 (Week2): New Technology

Potential and side-effect of Mobile Technology  Using mobile application to review the previous own learning in a classroom   Answer 1.      I believe Mobiles will have the greatest impact for instruction. As the Horizon Report mentions, over 75% of internet users in Japan already use a mobile as their first choice for access. Also, manufacturer Ericsson reports 80% of people accessing the internet will use with their mobiles by 2015. As these numbers show, a great number of populations are using mobiles in their lives. In addition, considering the current trend toward the consolidation of open-source mobile operating system platforms [1] and that mobile phone ownership among children has increased by 68% in the past five years [2], there could be no better time to take advantage of these affordances.      A myriad of populations and affordances including children can support the assertion that mobile technology...

Week2 : learning HTML & CS

-
I majored in electronics engineering and have been working in the IT field for many years. Most people can expect to be able to do all sorts of coding if they work in the IT field, but that's not true. IT is a huge field and there are too many sub-fields. It is the same that being able to speak doesn't mean they can speak all languages. I knew a little about HTML & CSS, but I haven't coded them properly until the present. Self-study of HTML & CSS gave me a good opportunity to actively interacting with learning content, searching for more resources, merging my previous knowledge of HTML & CSS into the newly acquired knowledge, and applying the new knowledge to creating web-based instruction. I reviewed multiple websites and watched several videos to better understand how basic elements of HTML & CSS were implemented into the web formats, and learn how to design my instruction in the website. I will not master web development, but I will be able to what HTML ...
