Abstract:
With the advancement of information technology, programming education has been considered important gradually. However, with the increase of programming course hours required in Curriculum Guidelines of 12-Year Basic Education, the speed of teacher training is unable to meet the demand obviously. Currently, visual programming language is widely applied in teaching programming in Taiwan in hope of helping students focus on semantic training to enhance the effectiveness of their computational thinking, whereas, there are still many difficulties in the learning process due to the lack of teachers. As a result, this research explores the usefulness of using intelligent hints to assist students in programming, anticipating the provision of different assist methods for programming teaching to enhance learners’ problem-solving ability and learning outcome. The subjects are novice programmers in the first year of college. There are two types of questions in the test. The data-driven hint generation technology is used to generate two hints as learning scaffolding, which are “Randomizing Line Numbers of the Solution” and “Multiple Choice Cloze Test”; in turn, they help to avoid hint abuse. After the experiment, students are asked to fill out the perceived usefulness questionnaire. Lastly, this research compares the effects of the two hints according to the data collected from the questionnaire. It is indicated that fill-in-the-blank questions are more helpful for programming exercises, while retaining the space for students to think independently.
