English Learning App Case study

Topic:

Many students have misunderstood, the software engineering course is the theory course? Or is there a few bulls who are desperately writing code, others soy sauce classes? Or do you learn a programming language and have a vocational training class? all wrong, software engineering has theory, there is practice, more important is analysis, speculation, summary . In the course, it is a good way to learn software engineering by organizing teams to write a software, and then analyze it, but we can also get a lot from others ' success/failure.

We have a lot of time in our lives to deal with the software, we have to play in class when the mobile games, buy train tickets website, contact with each other, QQ, and so are software, are worth analyzing. Why do you become their users? What did their team do right and what was wrong? Would you do better if you did it?

Through various case analysis, evaluation, debate, summary, we can see the principles of software engineering in the practice of all kinds of embodiment, learn software engineering, help us to do better in practice.

Evaluation software:

The first part of the research, evaluation

Download and use to describe the simplest and most intuitive personal first-time experience.
1, the screen is clean and fresh, mainly without advertising (unlike some dictionary and a certain mountain word bully); a daily sentence is highly recommended, we learn English in the accumulation of the accumulated.

--------Good, good------------

Part II Analysis

Using all the features of this software (including back words, word challenges, oral exercises, etc.), contact the second part of the analysis to estimate how much time this project will take (team size is around 6 people, computer university graduates, and have professional UI support).

I think it's going to take about a year.

Analyzing the current merits of the software (compared with similar software, at least 2 software), infers the important aspects that the software team can improve in terms of software engineering (specific recommendations). The results of the comparison are asked to List a table comparing the advantages and disadvantages of each software.

[Additional questions] for different dimensions of the score, the user experience, UI aesthetics, core functions, respectively scored (can give more detailed score more excellent).

	Interface	Language	Interpretation	Offline download	Score
