INTRODUCTION Research on teaching and learning of mathematics has become an area of research focusing on the teaching of mathematics in the past decade. Studies have indicated that teachers need to equip themselves with more flexible approaches (Galton & Eggleston, 1979) in the teaching of mathematics. The teaching and learning of mathematics is no longer regarded as only a simple and technical procedure involving teaching objectives and learning outcomes. Teachers are encouraged to adopt progressive teaching styles to accommodate the varied abilities of students, in order to enable these students to excel in their learning. Consequently, the teaching methods for teaching mathematics should be focused on serving the needs of learners by establishing a suitable learning environment for students. For mathematics teaching and learning, students are not only required to have knowledge of numerical facts, but also be adept in problem solving that are adjustable in accordance with their individual strength and weaknesses (Jones & Tanner, 2002). So, lessons in mathematics should be structured into three parts: a mental and oral introduction, the main teaching and activity and a conclusion. Effective teaching of mathematics does not depend on a fixed structure of instructional strategy but involves with a lively and interactive two-way process in https://creativecommons.org/licenses/by-sa/4.0/ 42 which students play an active part by answering questions and engaging in discussions, explaining and demonstrating their methods to others in the class where a rich set of teaching strategies is required from the teachers to ensure the effectiveness of the lesson (Sulaiman et.al., 2010). Calculus for Engineer 1 is the subject that helps to improve the thinking process and allows students to experience the creative thinking for self-problem solving. It is also the fundamental course for further learning in advanced calculus and engineering. However, there were many factors which negatively affected the teaching Calculus for Engineer 1 which resulted in the failure of being successful based on the goals of the subject such as the content of the subject itself which were overwhelming and difficult, the attitude of students towards learning mathematics, teaching time limitation due to the amount and difficulty, and the teachers lack of teaching techniques and materials. The researchers, therefore, were aware of the importance of the implementation of teaching techniques basing on the individual differences and the cooperative learning giving the students opportunities to develop knowledge, analyze and synthesize information, think creatively and critically, be able to search for information by themselves, to be continuously develop themselves, have working skills, and work with others (Parchagool et.al., 2016). It is utterly challenging for teachers to help students learn mathematics effectively. Teachers have to realize that a single teaching method is insufficient (Sulaiman, 2011). Effective teaching strategies are essential in ensuring a successful teaching and learning process. Individual qualities within each teacher have been recognized as a major influence on their capacity and ability in creating opportunities for their students to learn effectively (Ball & Perry, 2009). Discovering the effective teaching strategies that teachers are comfortable with in teaching and students learn with happiness and in a relaxed manner will be beneficial for learning mathematics. It is important to mention that all learning materials should include opportunities for students to develop their strengths and strengthen their weaknesses in each particular intelligence area (Lash, 2004). Therefore, it is necessary to assess the effectiveness of our current teaching style and consider innovative ways to improve our teaching to enhance the teaching and learning effect (Delaney & Shafer, 2007). Regarding the situation mentioned earlier, the researchers studied the theory of multiple intelligences (MI) of Howard Gardner (1983) basing on the belief of different capabilities and abilities of individuals resulting in the different functions of brain which affect the multiple intelligences in one person. This theory influenced on the principle of education aiming at developing the students to be complete persons, paying attention to individual differences, developing students based on their actual capabilities and aptitudes, integrating arts, self-awareness, communication, and promoting body language (Ezeh et.al., 2021). According to Gardner (1996), Multiple Intelligences included: Linguistic Intelligence, Logical-Mathematical Intelligence, Spatial Intelligence, Musical Intelligence, Bodily-kinesthetic Intelligence, Interpersonal Intelligence, Intrapersonal Intelligence, Naturalist Intelligence, and Existential Intelligence. The teaching that relates, connects, and integrates multiple intelligences can develop the intelligences of individuals regarding the potential of ones stimulating the learning, reducing the stress, and increasing happiness (Bullough, 2011; Keawchuer, 2014). The Team Assisted Individualization or TAI is the learning process which integrates the cooperative learning and individualized instruction. It focuses on group work. Each group consists of the multi learning ability including high, medium, and low abilities. The member of each group will be assigned a learning task that suites their learning ability. The members in the group will help each other to learn and work through sharing experiences for improving the learning ability, learning and working skills, and responsibilities (Adams & Slater, 2002; Peysner, 2021). In regards with the aforementioned, the researchers, as the lecturer in mathematics teaching Calculus for Engineering 1) are interested in studying the learning instruction based on the theory of multiple intelligences integrated with the TAI cooperative learning to improve the students’ critical and systematic thinking and mathematics process skills. The developed instruction was based on Limit Calculation included 3 steps which were : 1) Preparation 2) Teaching and 3) Formative and Summative Evaluations as illustrated in Figure 1. 43 Figure 1 Learning procedures 2.

DISCUSSION The results of the study revealed that the mean score of pre-test of learning through the learning activity developed by integrating the multiple intelligences theory and TAI cooperative learning which was 11.29 while the mean score of post-test was 31.29 respectively. This obviously shows that the mean score of the post–test was significantly higher than pre-test at the level of .05. This might be due to the fact that learning through the integration of the theory of multiple intelligences and TAI cooperative learning helped students to improve their learning via multiple ways of teaching and learning (using all 9 intelligences). The students could learn in the way that they prefer as a main approach, while the other less preferable ways of teaching might be the beneficial support of their learning. Moreover, they could use multiple ways to present their knowledge such as song mind map, pictures instead of using only writing work in the traditional classroom. Moreover, working in group under both interpersonal intelligence and TAI cooperative learning also helped students to learn effectively since they can help explaining, sharing ideas, or discussing for finding the answer and solving problems in learning. When they feel satisfied or comfortable in learning, the results of learning are higher as well. This corresponds with the study of Sulaiman et.al. (2010) who stated that effective teaching of mathematics does not depend on a fixed structure of instructional strategy but involves lively and interactive two-way process in which students play an active part by answering questions and engage in discussions, explaining and demonstrating their methods to others in the class where a rich set of teaching strategies is required from the teachers to ensure the effectiveness of the lesson. Moreover, the success of the integration of theory of multiple intelligences with the TAI cooperative learning for teaching mathematics in this study was supported by the study of Serin et.al. (2009) who proposed that teachers should be aware that there is no single and absolute method in 47 any teaching and learning process. Regarding what has been discussed, these were the reasons why the developed lesson plans based on the integration of the theory of multiple intelligences with the TAI cooperative learning could help students get the higher learning achievement. The mean score of the students’ satisfaction on learning through the developed the lesson plans on of Calculus for Engineering 1 subject on differentiation of algebraic functions basing on the theory of multiple intelligences and TAI cooperative learning was 4.61 which was the highest level. This might be the fact that the developed lesson plan and learning activities encouraged students to learn happily and effectively since there were multiple ways of both teaching, learning, and presenting knowledge are well-designed to serve the different needs and aptitudes of students. When they had a chance to learn in the manners that they like, they could learn happily and effectively. Due to the high satisfaction of students in learning, it encouraged to learn effectively and actively since they have multiple ways wo learn and to express their understanding. This was supported by the study of Haley (2004) who mentioned that students in the experimental classes were more enthusiastic about learning and behavior problems were minimized. Teachers felt that their classroom management skills were enhanced. One surprising result of the MI study was the affective outcome that most students expressed positive feelings about teachers using a variety of instructional strategies as well as assessment practices that addressed the multiple intelligences. 6. SUGGESTION Regarding the results of this study, the researchers would like to present the suggestion for both utilization and further study as follows: Suggestion for utilizing the results of study 1. Teaching through the integration of both the theory of multiple intelligences and TAI is quite different from traditional way that almost all students are familiar with, the teacher who would like to adopt this teaching activity should, therefore, use the first hour of teaching explain the process of teaching and learning to help students understand the learning process and reduce problems in learning. 2. Since the teachers try to integrate all 9 intelligences in both teaching and learning, this might cause some problems for some students in creating individual work. The teachers who would like to adopt this teaching activities should, consequently, adapt the activities basing on the individual differences of the target students. Suggestions for the further study 1. The study of implementing the theory of multiple intelligences and TAI cooperative learning should be done with the other mathematics subject not only calculus such as mathematics for business to see whether the results will be similar as in this study. 2. Since most of the subjects in this study were male students, there should be the study on implementing the theory of multiple intelligences and TAI cooperative learning with the class that has a lot of female students to see whether the results will be similar as in this study. 3. Since there are 9 different intelligences regarding the multiple intelligence theory, to use all of them for teaching one subject might be difficult. So, there should be the study that investigates the suitable intelligences that are suitable for mathematics learning. 7.
