1. An apparatus for providing questions for learning, comprising:

a memory configured to store instructions which, when executed, cause the apparatus to perform operations;

a processor configured to, by executing the instructions stored in the memory, generate a learning screen on which text information and problem information are outputted at different time points, based on question information and a question solving type of a learner, output a question solving type evaluation request signal and a learning screen output signal including the learning screen, and output a learning evaluation request signal when an answer to a question of the learning screen is inputted; and

a display configured to output the learning screen in response to the learning screen output signal; and

a camera configured to generate an eye movement image by capturing an image of eye movement of the learner in response to the question solving type evaluation request signal,

measures a question solving time on the learning screen displayed by the display, in response to the question solving type evaluation request signal,

detects a sight area of the learning screen, at which the learner stares, based on the eye movement image generated by the camera, while the learning screen is outputted by the display,

determines whether a learner input answer is correct or wrong, based on an answer of the question information and the learner input answer, in response to the learning evaluation request signal, and

determines and updates the question solving type based on the question solving time, the correct/wrong answer evaluation result, and the sight area detected,

wherein the processor determines the question solving type based on a type determination target question and the sight area, divides the learning screen of the type determination target question into a text area and a problem area, and determines the question solving type based on a text area ratio indicating the ratio of the time during which the sight area stays in the text area and a problem area ratio indicating the ratio of the time during which the sight area stays in the problem area,

wherein the processor determines that the question solving type is a text concentration type, when the text area ratio is higher than the problem area ratio, and the difference between the text area ratio and the problem area ratio exceeds a maximum reference value,
