Review of Classbook e-textbook – VnReview

Classbook – electronic textbook Still a concept quite new in Viet Nam. Newly introduced by Education Publishing House in June 2013, the product includes an 8-inch tablet computer that integrates digitized content of 12 textbooks from grade 1 to grade 12 with the purpose of replacing conventional textbooks. often at all levels. However, in addition to reducing the weight of the school bag that students are using every day, what is a good Classbook that parents have to pay nearly 5 million to own it?

Classbook has been sold in more than 100 stores nationwide. Currently, users can order Classbook e-books directly on the website of the educational e-book JSC (EDC), hotline or buy at authorized stores. Classbook has built-in textbooks, exercises from grades 1 to 12, using the Android operating system has been modified to suit the learning of students, dual-core processor chip, 1GB RAM, memory 16GB and there is an expansion slot microSD … and is sold for about 4.8 million.

Following are quick reviews of VnReview about Classbook e-textbooks.

Classbook e-textbook

Design and feel

Considering the overall outside, the machine has a fairly simple design. The only highlight is the two dark borders on the top and bottom edges where the back is reminiscent of the design used on the Samsung Galaxy Tab 8.9 tablet.

Classbook owns 8.0 inch screen with 4: 3 aspect ratio equivalent to a traditional textbook. This is the hinge direction in the design that the manufacturer has calculated so that the students can use it comfortably like normal paper textbooks.

With only a machine weighing 500g instead of the whole textbook, the weight of the daily backpacks that children have to carry before is greatly reduced. However, compared to most similar sized tablets, this weight is not small, even a bit heavy. It is also much heavier than a daily textbook so the elementary students holding it will quickly get tired. Therefore comes with an additional cover machine just has the effect of protecting the machine, just can rotate and support the base on the table. Moreover, this leather case also makes the grip feel more firm when the machine is “naked” because the edges of the machine are slightly beveled and the back is a bit slippery.

Classbook shell material is made of plastic similar to the “Chinese” tablet costing about 2 million VND is sold on the market, when pressing on the back of the machine slightly subsided a bit, tap the click to feel Low-end product sensory.

The back of the machine we experience is painted gray like silver on the motorcycle. The Education Publisher logo with the device name and device code (ID) is printed quite clearly. This ID number is very important in identifying your device, but you do not need to remember this confusing character sequence because it will automatically be recognized when connecting to the management program (Classbook Manager) installed on the computer.

The bottom left corner has rows of small holes where the speakerphone is played. The speaker is placed in a suspended position, causing the device to lose its symmetry and be easily obscured during handling when using, resulting in the best sound to the listener. Even when not being covered, I found that the speaker of the device is not very loud, the bass is small, sometimes the phenomenon is timid when the volume up to full size.

The upper edge is cramped because it contains most of the Classbook’s communication ports, this design is like many cheap tablets on the market. These ports do not have lids, so they are prone to dust and do not look very favorable.

Top edge from the left includes: microSD card slot, reset hole, charging jack, HDMI connector, microUSB port, mic hole, headphone jack ….

The left side has the power button and the volume up and down button

For me, the on / off switch on the left side is not convenient to manipulate. If placed on the right side, when holding the device with your left hand and opening the case cover, your right hand will press this button more conveniently.

The right edge has no slots or buttons

The bottom and the other edges are rounded and quite smooth

The edge of the screen is a bit big, but it is suitable for students to use to avoid “mistaken touch” when holding. The screen of the device has a glossy mirror surface that is easy to catch fingerprints, when used much will show up fingerprints looking dirty and difficult to clean.

The manufacturer says the screen has a resolution of 1024 x 768 pixels, using IPS technology for true, natural color display and wide viewing angle up to 178 degrees. However, the use of tablets instead of textbooks will certainly more or less affect the eyesight of students. In fact, when adjusting the brightness to the fullest I found the screen quality is only average when used in bright light or outdoors because the brightness, contrast and resistance to glare is not good. In the classroom or indoor space is fine, sometimes also affected by glare.

8-inch screen, 4: 3 aspect ratio

As a learning device, the device does not have a webcam, but I think there should be a stylus to facilitate writing, drawing or underline students.

Currently, the device must be used through the Classbook Manager management software installed on the computer (Windows support, not yet supporting Mac OS) to download and manage content. In the near future, the WiFi connection will be opened to be able to directly download content from the bookstore.

Consumers now only have one option to buy this device and all 12 books from grade 1 to grade 12, the vendor does not sell the book separately and does not allow any other device to use this book. The fact that content must be used on a separate device raises questions about the Classbook’s exclusivity. The features of a tablet are virtually locked out. If users use Root and install another ROM, it will not be Classbook anymore but will become a normal tablet.

On the other hand, each device is used for a student, when parents want to teach their children, it will be inconvenient, perhaps not buy more equipment? Is such a non-premium device strong enough to accompany a student in grades 1 through 12?

Accessories and warranty

Comes with the device is a charger, headset, microUSB connection cable, leather case.

The headset has a soft, anti-tangle and ugly form. The plastic grip feels rough, light, and low quality. The design also doesn’t fit into the ear, so it feels uncomfortable and comes with a relatively low sound quality.

The synthetic leather cover protects the machine against impact and can rotate and support on the table.

Machine warranty for 12 months.

“Ecosystem” and content

Classbook has 310 textbooks, homework from grade 1 to grade 12 and more than 20 learning support applications. The content of textbooks must ensure standards and comply with the regulations of the Ministry of Education and Training. In addition, they are encrypted to avoid messy modifications and cannot be removed for use on other devices. When it is re-released or updated, it will quickly be downloaded without the cost of acquisition. Users do not have to worry about losing books downloaded by the machine ID has been verified, when the machine fails or changes to another machine it will automatically sync.

The book content is in a .pdf file, the feature of automatically viewing the text when enlarging is not available, leading to frame overflow, which takes 1-2 seconds after releasing the finger to bring the content to the resolution. tallest. This phenomenon does not occur on specialized reading machines such as Kindle, Nook …

Zoom in on overflowing content

The content of music books, English (from grades 3 to 12), literature, embedded interactive features with users or multimedia features such as emitting speakers, reading. In addition, users can highlight, write notes, take quizzes …

It also offers a set of learning tools, including a dictionary, a scheduling tool, a calculator and will continue to be updated on the Classbook Store …

… feelings about use

A wooden bookshelf-like interface like Apple’s iBook pops up when the device is turned on. On the bookshelves are the types of textbooks arranged in turn according to the class. This bookshelf is always fixed vertically but cannot be rotated horizontally, does not allow to enlarge, so it is sometimes difficult to find books because there are books with small names and color sinking text labels but quite similar labels. For example, the “Chemistry 8” book has a small, hard-to-see color “exercise”.

Users have 2 ways to switch back and forth between the shelves of the bookshelf: clicking on the edge of the sides (the support is only 1cm wide) or click the arrows on the sides of the dim border of the bottom of the display.

In addition to the three function buttons commonly found on the Android operating system (Back, Home and task buttons are running) along with the display of time status and battery level, the interface of Classbook bookshelf also has 2 buttons top right corner and 1 button in the left corner. The serrated button in the left corner is the Settings button, the user can adjust the brightness, turn on and off the silent mode, turn on and off the screen rotation mode, set the screen brightness time and set information label personal. The magnifying glass button when clicked will display a book search box in the shelf, just press the number 7 and then click on the magnifying glass below will quickly display all grade 7 books and the titles containing numbers 7 … Next to this button is a button with a 3 dash symbol. This button is a drop-down menu containing titles for books from Grades 1 through 12 respectively (including advanced books) and then to the common applications and books used. I find this button very useful when I want to quickly move to a bookshelf of each class or to applications that need to be used.

In the process of using it, I saw a slight lag when opening or quickly turning pages of the book. Open a book and zoom in. You’ll see it takes about 2 seconds to display in a clear state. When using the book search feature, the machine will produce results after 1 to 3 seconds depending on the search content and the results are listed down, sliding your finger to drag the screen to see the device jerky. I easily realize this because I have experienced many different tablets.

Interoperability of the machine with the user is an advantage but incomplete because it is still poor. When opening a book page, users touching the page surface 1 time will show two toolbars above and below. The toolbar below includes the main menu with features from left to right including: an arrow to the previous page, a button to return to the bookshelf, an interaction button, an active action button, a multimedia function button, a button Other apps and arrows turn the next page. If the book page has interactive content or multimedia content, the buttons will light up as shown below, when activated it will show a yellow bar at the bottom, if the page does not have these features then the buttons That will dim.

For example, in 1st grade music books there are many songs and each song is often digitized as 2 pages of books with its own purposes. Page 1 is the title of the song, the author and the lyrics are written as paragraphs like a poem, below is an illustration. When using the interactive feature, you can select each piece of music to listen to sample songs or you can click on the title or the first paragraph to listen from the beginning. Page 2 has additional music staves, notes of these songs and an interactive function that will play the entire song from the beginning, but cannot hear each paragraph like page 1 but students have illustrations and learn more about notes music. Can search for content related to musicians or other related songs. You can write notes on content pages.

English books in grades 3 to 12 incorporate many native voices to enhance listening ability, students can look up the meaning or hear the pronunciation of any word or paragraph by touching the word that on the screen.

In language arts, students can also listen to the teacher’s standard voice, learn the author’s biography, take a quiz or learn through textual instruction.

In 6th grade grammar books, essays are sometimes annotated with author biographies, multiple-choice questions or references that are teachers’ voice, related songs … and instructions on perceptual analysis. copy.

A little more about these interactions: the author’s biography is basic information about the author including the illustrations, the fonts displayed in this frame (this frame is quite small) is a thin font type , close to each other, unable to zoom in, so I don’t see clearly. This information is mainly obtained from and the internet. Multiple choice questions will appear with a frame showing the current question in the total number of questions, the questions above and below are the answers made in the form of multiple-choice questions, below are the calculations. Power: move to the previous question – the answer, the answer and the end. If you click on the answer, the program will give you the correct answer for that question.If you click Finish, the program will show a confirmation of the end.If ok, the results of all questions in that lesson will be displayed – which shows whether your result is right or wrong and a review mode for each question.

The multiple choice test on the machine can be done under either test or practice mode to help students self-assess their comprehension level as well as teachers and parents to monitor the test results.

However, as mentioned above, the ability to interact and mutimedia in the content of the book is low. The titles that need such content as: geography, biology, history … are not yet available.

Battery life

If I use the device continuously, I can use it for about 7 hours, which is enough for a school session, if the boarding school is full day, I need to charge more.

It takes about 4.5 hours to fully charge the battery.

Using continuously for about 1 hour, I found that the hottest area was at the surface edge of the top right corner of the screen, the other areas on the surface were almost cool.


Investing VND 4.8 million for a tablet integrated with educational content is still too expensive compared to the cost of buying paper books and learning tools. Moreover, besides the price “acrid”, the quality of new equipment is the issue that consumers are most concerned about. The current quality of the Classbook cannot satisfy users.

The device is a bit heavy for elementary students, especially for grades 1 and 2, but it is a bit small and monotonous for high school students. So the manufacturer offers more equipment options, improved improve device quality and also have additional application packages that allow users to choose the solution that best suits them?
