A vocabulary tool for ESL teachers to increase student’s audible/reading comprehension.
This app helps students to learn and practice vocabulary that may have been taught in class, but which they have not yet mastered.
Students who are completely new to a language, and especially those whose prior knowledge differs highly from the target language, cannot read the directions in the target language. So the app plays audio of a word, and the student simply taps or clicks the tile that shows the correct word.
This app is most useful to students who can both see and hear, but the word also appears above the tiles, so deaf students can also benefit. It is also useful for teachers to see the students’ progress. The app will keep track of students’ average score per category as well as per quiz and display them in an admin area that only the teacher can access.
We used Vue.js are the UI frameworks with Nuxt for SSR. We use Express to write the REST API which connect to the PostgrSQL database running in a Docker instance. We used Google’s Firebase to handle user authentication and implemented a QR scanner to make logins simpler for illiterate students.

Trong bài viết này, tôi sẽ cố gắng hướng dẫn cách tạo một bảng động trong react. Tôi biết nó khá đơn giản, nhưng hướng dẫn này dành cho người mới bắt đầu và người mới bắt đầu nên biết cách thực hiện loại công việc này., Ý bạn là giả sử bạn muốn tạo bảng 3 × 4? Tôi không thực sự chắc chắn nhưng bạn có thể lưu trữ số hàng và số cột thành biến và dựa vào đó tạo bảng. , cách thêm tìm kiếm và sắp xếp trong bảng

В этой статье я постараюсь научить создавать динамическую таблицу в React. Да, я знаю, что это довольно просто, но этот урок предназначен для новичков, и новичок должен знать, как это сделать. Вы имеете в виду, что, скажем, вы хотите создать таблицу 3 × 4? Я не совсем уверен, но вы можете хранить номера строк и столбцов в переменной и на основе этого создавать таблицу. , как добавить поиск и сортировку в таблицу
