-E-BOOK Electronic workbook typed in electronic-book and sheet workbook using proof relationship between given text and item

摘要

One embodiment of an electronic workbook based on e-book comprises: a user key input unit which receives an order from a provider of pre-registered questions, and a user answer; a display unit which provides the pre-registered questions; and a control unit which, if an order from the provider of the pre-registered questions is received, provides the pre-registered question to the display unit to take a test, and evaluates a user answer of the question. The pre-registered questions comprise a question in a text type having objective choices, and the text is a proof text and classifies the text by preset content units to have a plurality of reading content logic sections, indicates a reading content logic section for each of the reading content logic sections, matches a reading content logic section identifier for identifying other reading content logic sections, respectively, and writes names. The objective choices of the text are relating objective choices having correlation with the reading content logic sections of the text. The control unit provides the proof text and the relating objective choices to verify whether objective choices are valid or not, when a question in the text type is provided, and gathers objective choice answers comprised of user selection objective information and semi-objective choice answers comprised of a user selection reading content logic section identifier, and applies the same to verify whether the objective choices are valid or not, and to evaluate user answers. Due to the present invention, a thinking power for increasing accuracy of question judgment and for discovering a logical correlation between a text and choices can be improved.
