2.1. Mathematical Creativity
There are plural definitions of mathematical creativity. Mathematical creativity, compared to creativity in a more general sense, is widely known as the ability involved with concept-developing and problem-solving processes in mathematics. Early theories on mathematical creativity include Poincare’s research on creativity as insight through intuition in relationships between mathematical problem solving and the unconscious. Wallas [
12] posed another early theory of mathematical creativity, claiming that creativity is nurtured from the unconscious work of incubation and then externalized through symbols, words, and logic. These early studies of creativity contributed to the theoretical foundation of mathematical problem-solving models thereafter, such as Polya’s and Schoenfeld’s notion of heuristics.
As problem solving has become a regular part of mathematics instruction, so has the educator’s interest in framing creativity within the strategies of problem solving. Divergent thinking is often used as a strategy to generate multiple creative ideas, and is regarded as an important component for mathematical creativity by contrasting convergent thinking. Convergent thinking is a technique that structures and organizes various ideas from different participants and attempts to culminate in one best solution to a question. However, both are crucial for developing mathematical creativity as these strategies point to the importance of connecting existing ideas in order to build new ideas. When mathematical creativity is defined as the process of making unique and insightful results for a problem, this connection of building ideas is an important process in mathematically creative thinking [
13].
On the other hand, research proposed different types of mathematical creativity for different contexts. For instance, Liljedahl and Sriraman [
14] suggested distinguishing school-level creativity from professional-level creativity. Professional-level creativity refers to originality or ingenuity in academic products for discovering what was previously unknown. School-level creativity is the process of developing exceptional and unconventional solutions in problem solving. School-level mathematical creativity also encompasses gaining the knowledge of school mathematics, integrating disconnected ideas, and building new relationships. As described next, considering creativity in this study, we noted the importance of mathematical tasks that afford students opportunities to communicate and use tools in describing an appropriate level of creativity for students.
2.2. Creativity Education Program in the Study
In designing a unit to support participants as they learn to conceptualize a pedagogy for facilitating student creativity in the mathematics classroom, we propose a student-centered method consisting of three specific approaches: storytelling, use of manipulatives, and use of multiple representations. More specifically, our curriculum provides preservice teachers with educational contexts in which students participate in story-based, problem-solving tasks using technology or manipulatives. The use of technology and manipulatives allows students to explore various representations of mathematical thinking and reasoning, and to produce diverse solutions to problems; our participants were asked to engage in these problems as learners.
This approach builds upon a research base on the educational opportunity to (1) build a rich conception of situations and to express concepts and ideas through
storytelling [
15]; (2) build relationships between concepts and objects through the use of
manipulatives; and lastly (3) link relationships in a network of ideas and to engage in problem solving through the use of various
representations, including those demonstrated through technology. In this way, the use of storytelling, manipulatives, and multiple representations combine to afford meaningful opportunities for students to engage in inductive reasoning, synthesis, and ultimately creativity in the mathematics classroom [
16].
Table 1 shows the literature to categorize subdomains of creativity and to support our rationale for the connection between creativity and teacher practice in the classroom [
7].
Storytelling. Teachers can use stories as a learning tool in the mathematics classroom [
15]. More specifically, stories can foster creativity in students by prompting their interest, curiosity, sensitivity, and imagination about mathematics. These stories can be told through mathematical enrichment activities, using the history of mathematics and mathematicians, diverse mathematical ideas, structures, modeling situations, and other cultural artifacts [
28]. As the teacher tells stories, students can use the information, as well as their imagination, to understand the narrative accounts and construct their own. In this sense, stories can engage students in the process of learning [
29].
Use of manipulatives. Use of manipulatives in the mathematics classroom is a student-centered process in which students touch and move objects while they explore and connect mathematical ideas to ultimately expand their creativity. Manipulatives are cognitive tools that are a dynamic visual representation of otherwise abstract mathematical ideas. The theory of experiential learning states that learning is meaningful when students acquire knowledge through active processes that engage mind and body [
30]. Further, an appropriate use of manipulatives enables students to objectify abstract concepts, helping students transition from concrete experiences to abstract reasoning [
31,
32,
33].
Use of multiple representations. Mathematical representation refers to the ways of capturing an abstract mathematical concept or relationship [
34]. A mathematical representation may be either symbolic in nature or more of an internal way of thinking about mathematical meanings [
35]. Regardless of their form, Duval [
36] asserts that representations are essential to communicate meaning drawn from or evident with mathematical objects and concepts. For example, using multiple representations can support students in visualizing (e.g., diagrams and graphs) mathematical concepts, making connections, and creating new ideas. Through activities with multiple representations, including various modes of expression (e.g., speaking, writing) for communication, students broaden their repertoire of illustrating mathematical ideas and gain deeper mathematical understanding.
2.3. Character in Mathematics Education
Character is defined in the field of education as moral qualities, ethical values, and responsibility for self and others in society. Character education involves students developing a moral sense and positive character traits [
37]. Traditionally, character education in schools belonged to civics classes which taught respect, responsibility, and caring for family and community members. However, there has been increasing interest in teaching moral and civic virtues through academic content [
38,
39]. Interest has also risen as to how the kinds of civic education that promote a responsible citizenry can be used in conjunction with curriculum on creativity. Particularly, the national curriculum in Korea [
40] emphasizes the key abilities of creative thinking and a sense of community; competence of each is related to character education. Similarly, in the U.S., Common Core State Standards for Mathematics [
3] highlights the mathematical practices involving perseverance in solving mathematical problems in addition to the mathematical content. In this study, we use the term
character not to distinguish it from other terms, such as disposition or personality, but more to attend to the kinds of social–emotional development promoted and nurtured through learning in educational contexts.
Educational philosophers such as Pestalozzi, Herbart, and Froebel have highlighted character education as an important component of mathematics education [
41]. According to Pestalozzi, the goal of mathematics education as an essential discipline to cultivate character is developing cognition and powers of thought. Similarly, Woo [
42] stated learning mathematics paralleled performing mental gymnastics such as judgment and inference, thus teaching mathematics to include character education can lead students to exercise judgment and justice in the moral sense. These views point to the potential of mathematics instruction to inculcate not only the nature of mathematical truth, but also aesthetic and moral values.
2.4. Character Education Program in the Study
Beginning with group processing [
43], we attended to the importance of learning through positive interactions with others in the classroom. This theory posits a close relationship between positive interdependence and cultivation of character through how relationships with peers influence individual behavior for psychological process and goal achievement.
Our approach builds upon a research base to identify three process-based teaching practices with the potential to foster student character.
Table 2 shows the literature that supports the connection between the elements of character and teacher practices to promote process-based learning in the classroom.
Classroom norms. Classroom norms are an important construct for the analysis of classroom cultures [
48]. In this study, we considered socio-mathematical norms of the classroom community, including the normative aspects of student behaviors and interactions in the learning of mathematics [
49]. The development of classroom norms would involve students debating acceptable social norms and ways to participate in mathematical discourse in order to create a safe and productive mathematics-learning environment. Then, the students selected the norms for their classroom and learned to cultivate acceptable social and mathematical behaviors, which are evident in character traits such as: respect, kindness, responsibility, helping, persistence, reasonableness, and/or productivity. As classroom norms are associated with future behavior in the classroom [
50], when students exercise the classroom norm, for example, supporting each other in listening actively, contributing ideas, and sharing struggles, students have the opportunity to build characteristics such as kindness, respect, and productivity.
Collaborative learning. Collaborative learning is an educational approach in which groups of learners work together to accomplish shared learning goals [
51]. Research has claimed that as students participate in collaborative learning and practice social skills, they have the opportunity to develop core virtues such as leadership, responsibility, and cooperation [
52]. In this study, the meaning of learning mathematics is believed to lie in the participatory opportunity to communicate mathematical knowledge with others in the community. Therefore, collaborative learning can provide space and opportunity in which to develop concepts within the learner and to use the communication with others as negotiation of knowledge and experience to change thinking with new or improved ideas. As the learner works collaboratively with the teacher and peers, and as they participate in the negotiation of knowledge and ideas, the ability to listen to others and engage in this meaningful conversation may positively address a number of emerging challenges such as bullying or harassment.
Multirater feedback. The multirater feedback approach is a type of assessment in which individuals working as part of a group are asked to offer feedback on the peer’s performance [
53]. Multiple performance feedback provides a student with the opportunity to analyze, assess, and improve his or her learning in light of support and collegial feedback from members of the classroom community. It makes the student aware that being successful is not solely about pleasing the teacher—success is identified in the
process of working with peers, helping others who share goals or problems find success, and improving oneself. In the context of this study, multiple methods of assessment for character education such as group-, peer-, and self-evaluation are designed and implemented in the classroom. Evaluations by teacher, self, and peers are intended to enrich components of character such as responsibility and fairness in oneself, as well as in the classroom norms which reflect the values and beliefs of the classroom community. Additionally, designing assessments in which students engage in evaluating knowledge across various modes of communication can help individual students recognize the intellectual contributions of others in the community as equal in value to the dominant knowledge.
Integrated approach: Creativity and character education. In the study, we define creative character education as an integrated educational approach which fosters both mathematical creativity and character in the mathematics classroom. Our design of the creative character education program is summarized in
Figure 1.
Research on creativity in mathematics education has been conducted separately from the research on character education. An education geared towards creativity may overlook the importance of cooperation and group work, while on the other hand, character education may overlook mathematical content. While multiple studies on mathematical creativity education have provided investigation into concept, learning, teaching, and problem solving [
13,
54], there have been few studies on character building in mathematics education. In light of the need for research on the integration of creativity and character education, to include the initial pedagogical models in teacher education, this study investigated a new model of pedagogy in the context of teacher education. Extending the literature on creativity and character in education, we frame creativity in the mastery of content through pedagogical strategies such as storytelling and the use of manipulatives and representations. Character education is framed in the process (not product) of participatory learning through classroom norms, collaborative learning, and multirater feedback.
