1. Introduction
In the field of computer science, artificial intelligence (AI) has experienced several golden-age periods after the concept was first agreed at the Dartmouth Conference in 1956, but faced a dark age due to the limitations in research because of the underlying hardware technology and difficulties in commercialization [
1]. However, since mid-2010, we have been facing a new revival due to the development of neural networks and parallelization processing technology, and a significant amount of research based on this is being conducted in academia as understanding and using AI is a very important factor in future human life and national prosperity [
2,
3]. It is causing many changes and innovations in all areas, such as politics, economy, culture, and education in modern society [
4]. In line with this trend, countries around the world consider AI as their major future project for their country and are sparing investment and support, and this is also the case in education [
5]. Education for adolescent students is a process to prepare for 10–20 years into the future, when these students will participate in economic activities. In other words, it is necessary to consider not only the immediate changes in the present, but also in the future, 10 to 50 years after the learner becomes an adult and a member of society [
6]. Students’ current learning experiences can have a profound impact on their lives and help guide their overall life. Therefore, there is no shortage of artificial intelligence education (AIED), even if it plays a pivotal role in forming the future of human society and contributing to the national economic development. Therefore, providing an appropriate approach to AIED and an effective learning experience is an important task for education officials.
What is the goal of education? It is to achieve the learning goals according to the specific subject and learning elements, to gather these achievements to logically solve the problems encountered in one’s life, to feel the beauty of life, and to nurture a holistic human being who enjoys life [
7]. Therefore, educators and administrators must provide specific and meaningful education so that the knowledge, skills, and attitudes that students have experienced and achieved in school education can be used meaningfully in the lives of learners beyond simply experiencing them. Various teaching and learning methodologies have been proposed to ensure the significance of education and help students to be truly useful in their lives, and STEM education is also one of the effective methods. STEM education provides an experience that allows students to acquire knowledge and skills in science, technology, engineering, and mathematics in the course of solving real-life problem situations and use them meaningfully in their lives [
8]. Numerous studies have confirmed that STEM-based learning has a positive effect on learners’ knowledge utilization, proving the importance and effectiveness of STEM education in the modern curriculum [
9].
As a content element of learning, AI education is essential from the perspective of sustainable education to prepare for the future, and in terms of learning methods, STEM education is an effective way to help learners use the knowledge acquired in education meaningfully in their lives. This study aims to develop a STEM-based AIED plan by linking the importance of the content of AIED with the method efficiency of STEM education and apply it to analyze the educational effect. Despite the effectiveness and importance of STEM-based AIED, very few related studies have been conducted, and research results on elementary school students targeted in this study are harder to find.
The research objectives that guide this study are as follows:
Develop a STEM-based AIED program using backward design for K-12 students.
Measure the effectiveness of the developed program on students’ creative problem-solving ability, literacy of AI, and attitude toward AI.
3. Methods
3.1. Backward Design
Tyler’s curriculum design method, which has been used as a method for setting up an education plan for a long time, consists of goal defining, learning experience selection, learning experience organization, and evaluation, which is called forward design [
34]. In the past century, this forward instructional design has been practiced by many schools and teachers and has produced excellent educational cases and research results, but the learning goals and the contents of the evaluation plan are not connected to each other, and there is a gap or the results of evaluation are not satisfactory. It has also caused problems that could not be utilized for intellectual growth. In the teaching and learning scene, the purpose of evaluation is not to classify and rank who is good at what, but to help each learner achieve their learning goals by examining student achievement and understanding the level of each student. If the viewpoint of evaluation focuses on the growth of students in the process of learning rather than the learning outcome, the organic relationship between learning content and evaluation becomes important.
The backward method of instructional design can focus more on the educational use of evaluation. The backward instructional design [
35] direction proceeds by identifying desired results, determining acceptable evidence, and planning learning experiences and instruction. It is different from forward teaching and learning design in the order of the evaluation plan, and it is also called reverse teaching and learning design. This has the advantage of focusing the content of the evaluation thoroughly only on the learning goal and preventing the provision of a learning experience that is not related to the achievement of the goal [
36]. As shown in
Figure 2, the STEM-based AIED program developed in this study was also developed through backward design to focus on the achievement of students’ achievement of AIED learning goals.
3.2. Research Participants
To investigate the effect of the STEM-based AI education program developed in this study on learners’ creative problem-solving ability, literacy of AI, and attitude toward AI, 120 students in five classes in grades K–6 of elementary school were targeted. It was applied for one semester. Curriculum during this period consisted of the application of development materials as well as classes of general other subjects individually. All the participating students (62 males, 58 females) were subjected to verification and statistical analysis of the application results. Instead of conducting classes in a separate computer room, the smart devices provided in the classroom were actively used, and hence, an environment for using one device per person was prepared. Teachers with more than 10 years of experience held a pre-training session and a monthly meeting to discuss the progress of the class and effective learning process to improve their competency to operate the developed program.
Prior to the experiment, participating students responded to two types of preliminary questionnaires and the results are shown in
Table 3. The first survey was conducted to determine the use of information devices during class activities as a question asking students’ ICT using ability, and the average result was 3.89 (5-point Likert scale). The second survey is a question that asks students about their experiences with various teaching and learning methods, such as cooperative learning, convergence class, and inquiry learning, to choose effective learning ways during the STEM class. They answered that they had experience in various teaching and learning methods, and that more learning occurs in the process of exploring and discussing with peer learners rather than transferring knowledge from the teacher. In addition, the students subject to the experiment had sufficient experience in computer programming education using Scratch and using ICT devices and were familiar with teaching methods, such as cooperative learning and convergence education, as well as traditional classes. The actual class was conducted as a method of collaborative learning with peer learners and inquiry learning that guides them to solve problems on their own.
Students participating in this study were informed that they would participate in the pre-post-developmental test in the form of a questionnaire, and that the questionnaire had complete anonymity and non-identification. In addition, it was announced that the results of the test are not analyzed for each individual, but values such as the average score and variance are calculated for each group. As such, the contents of the test were thoroughly guaranteed anonymity and there was no room for infringement of individual rights, but the experiment was conducted on non-adult students, so written consent was obtained from the students’ parents or guardians regarding the experiment and participation guide.
3.3. Data Collection and Analysis
In this study, students were asked to respond to two types of questionnaires. The first was a questionnaire for quantitative analysis. It consists of a creative problem-solving ability test tool (2004, MI Research Team, Psychology Lab, Seoul National University) and two types of AI-related questionnaires (AI literacy, AI attitude). The reliability of Cronbach’s alpha for the creative problem-solving ability test tool is 0.93 and consists of four sub-domains: self-confidence and independence of learners, divergent thinking, critical logical thinking, and motivational thinking. Creative problem-solving ability is an important competency in a learner’s life, and the sub-elements of this test tool are good indicators to check how they affect the development of problem-solving ability, which is very important to students. Therefore, it can be confirmed whether the effect of STEM-based AIED is a stepping stone for sustainable growth and meaningful learning in a student’s lifetime. The AI-related questionnaire used the test tool of Chang-mo Yang (2022), and this test has a total of 17 questions, with a total of 5 questions on AI literacy, consisting of a 1-point to 4-point Likert scale and its Cronbach’s alpha is 0.72. Scores of 1 were “I do not know at all”, 2 points were “I have a memory but I don’t know”, 3 points were “I know but I can’t explain it”, and 4 points was “I know well and can explain it well”. The AI literacy area asks how well students understand the meaning of AI and how it affects our lives, and how students can use and apply AI in the process of solving their own problems. The remaining 12 items are about AI-related attitudes and consisted of a Likert scale ranging from 1 to 5, with 1 being “not at all”, 2 being “not at all”, 3 being “normal”. A score of 4 was measured as “agree” and a score of 5 as “strongly agree”. Attitude towards AI is an ethical area of AI, which is about the positive and negative effects of using AI, and the tendency to use AI in life. Details of the questionnaire for quantitative research can be found in
Appendix A. The results of these surveys are statistically processed in SPSS to prove their significance.
The second type of survey is a satisfaction survey for qualitative surveys. We received participants’ opinions about the STEM-based AIED program in a free form and qualitatively analyzed participants’ tendencies, interest, and immersion in the development program using ORAGNE3’s text mining technique. All questionnaires were presented in Korean and responses were received in Korean in consideration of the age of the test subjects, and for qualitative analysis, they were translated into English that can contain the same meaning as much as possible.
5. Discussion and Conclusions
With the innovative increase in computing power, large-scale parallel processing can be efficiently processed; therefore, artificial intelligence technologies, such as classification, regression, and natural language recognition, are being developed explosively. In the future, AI computational ability will be used more actively in various fields of human society, and creative problem-solving ability using AI is an essential competency for students who will live in future society.
STEM education is an effective educational methodology that helps students not only know what they have learned, but also applies them to real life. There are various views on AI education, but in this study, it was viewed from the perspective of providing an experience of problem solving using AI. Therefore, in this study, a STEM-based AIED education program for elementary school students was developed and applied to present problem situations that students can encounter in real life and to solve problems by linking various academic contents, including AI. The theme of the developed program took into consideration the interests of the students and their social issues. The selected topics are about creating a program for the socially disadvantaged, an infectious disease prevention system based on mask recognition, and conservation of the ecosystem, and the details were explained in
Section 4.
This study aimed to investigate the change in creative problem-solving ability, attitude toward AI, and AI literacy. In addition, by receiving students’ free opinions, sentiment analysis was conducted on the student’s thoughts on the development program and AI. The experiment was conducted for K–6 students, and the results of this study are as follows.
First, an AI education program based on STEM education was developed for students to use AI. The level of difficulty was set for the program to suit the developmental level of the students, and it was structured to proceed through discussion and cooperative activities from setting up a plan to solve problems on their own, to implementing them, and organizing the results.
Second, to review the effectiveness of the development program, pre- and post-tests were conducted on creative problem-solving ability, attitude toward AI, and AI literacy. In all three items, the post-test results were improved compared to the pre-test, and statistical significance was confirmed. In an age based on AI, creative solving ability that thinks about solutions to problems in various ways is very important, and education should also be set in the direction of using AI and enhancing creativity. The results of our study could be the basis for these claims.
Third, as a result of the emotional analysis of free-form responses to questions about the development program and one’s own thoughts on AI, positive results were found in all analysis methods, and through this, it was confirmed that the STEM-based AIED education program provided students with a positive perception of AI and a learning experience. The fact that students have a positive perception of AI can also be said to have increased their tendency to accept AI technology in the future. In other words, by using AI in problems where AI can be used in students’ lives, attitudes to make their lives more enriching and convenient for themselves are formed.
Looking at the above results, the STEM-based AIED education program developed by us had a positive effect on students’ creative problem-solving ability and basic literacy and attitude toward AI. Therefore, education officials should consider providing real-life-oriented problem-solving experiences using AI among various educational contents when composing the curriculum and teachers should also recognize the importance and value of convergence education that includes the use of AI.
This study is a STEM-based AIED program for K–6 students, and it has specificity and differentiation compared to other studies. However, it cannot be denied that the classification model consisting of text and images is mainly used among various AI fields and that the main content is simulation programming to solve problems. Research to develop various AI-related educational programs for students who are the future leaders and to confirm their effectiveness should be continuously conducted. This study—the development and effectiveness analysis of STEM-based AI education materials for elementary school students conducted—serves as a beacon of a new field of AI education and STEM education, and we hope this article can inspire you to research practice.
