Introduction
Learning media has a significant role in the learning process (Durmaz, 2023;Sulistyawati et al., 2021).One of the important roles of learning media is as a means to channel messages from teachers to students (Ain & Mustika, 2021;Yasa et al., 2020).This statement is supported by Latifa et al. (2020) which states that the application of learning media aims to transfer learning materials that can facilitate the development of student learning abilities.In line with this opinion, Suryaningrat et al. (2021) states that the use of learning media can also provide motivation and enthusiasm for students in developing students' conceptual understanding skills.Septinaningrum et al. (2021) also states that learning media is an alternative for teachers to achieve learning goals and create quality and interesting learning.
This learning media makes it easier for students to understand the material provided (Aksoy et al., 2022;Yasa et al., 2020).At the elementary school level, learning media that are easy to use can attract students' attention in learning (Syamsi & Dharma, 2023;Yasa et al., 2020).This condition occurs because elementary school students are still at the level of concrete thinking, where they learn better by seeing, feeling, and trying something independently (Andini et al., 2023;Hermita et al., 2021;Kayhan, 2022).
Teachers need to facilitate students' curiosity and motivation in learning (Özdemir & Gundogan Onderoz, 2022).This is necessary because students' curiosity and motivation can improve students' critical and creative thinking skills (Hermita et al., 2021;Korkmaz et al., 2022).One step in facilitating student curiosity and learning motivation is the use of media in learning.Suryaningrat et al. (2021) states that learning media can facilitate students in understanding the concept of the material being taught.Interactive learning media that integrates contextual problems make it easy for students to understand the material being taught (Utomo et al., 2021).This statement is supported by Rizqiyana et al. (2021) which states that the application of thematic learning media based on the STEM approach can develop students' critical and creative thinking skills.
Teachers still use conventional learning methods,therefore they have not been able to facilitate students' abilities as a whole (Pereira et al., 2021).This statement is in line with the results of research Yasa et al. (2020) which states that the results of the analysis of the learning process show that teachers do not use interesting learning media and students do not pay attention to teachers during learning.This condition is in line with the opinion Dinayusadewi & Agustika (2020) which states that there is still a lack of application of interactive learning media by teachers in elementary schools.This condition occurs because there is still a lack of understanding and ability of elementary school teachers in designing mathematics learning media (Ain & Mustika, 2021;Widiastuti et al., 2023).As a result, the teacher has difficulty conveying material, especially for abstract material.Therefore, interesting and appropriate learning media are needed to facilitate the process of understanding student material (Gusteti et al., 2021;Subanji et al., 2023).
Learning media that are in accordance with the characteristics of elementary school students which contain elements of images, text, animation, and illustrations that have been adapted to learning materials (Aprilia et al., 2023;Fatkhiyani & Dewi, 2020;Triwahyuningtyas et al., 2022).The application of this learning media makes students become active in participating in class learning (Anggito & Sartono, 2022;Firdaus et al., 2022).One of the learning media that can be implemented in elementary school learning is the picture story book learning media.
Picture story book learning media is a learning media that contains aspects of images, text, and practice questions (Parwati et al., 2022).Sources state that students become more active in learning in class when learning by utilizing this picture story book learning media (Farindhani & Wangid, 2019).Therefore, this study aims to determine the effectiveness of using picture story book learning media to develop critical and creative thinking skills for fifth grade elementary school students.

Methods
This study aims to determine the effectiveness of using picture story book learning media in terms of critical and creative thinking skills of fifth grade elementary school students.This study uses a quantitative approach with experimental research.This experimental research uses a quasi-experimental design with a pre-test and post-test design.In this study design, there was an experimental class and a control class which were not randomly selected but had been selected from several elementary schools as research subjects in cluster IV of Sintang District.This research was conducted at several elementary schools in cluster IV of Sintang District, West Kalimantan, Indonesia.
The subjects of this study consisted of 50 grade V elementary school students in cluster IV of Sintang District.The subjects of this study were taken from 25 students at Sintang 7 Elementary School for the experimental class and 25 students for the control class at Mambok 20 Elementary School.The sampling technique uses purposive sampling with research samples that have been determined according to the knowledge possessed by students, namely high, medium, and low abilities.
Data collection was carried out through questionnaires and test instruments.The needs questionnaire was obtained through the teacher's response to find out the initial problems of fifth grade elementary school students.The test instrument is used to measure the critical and creative thinking skills of fifth grade elementary school students.The feasibility of this research instrument was then tested using validity and reliability tests.Test the validity of this instrument aims to obtain a research instrument with a valid category.Test the validity of this instrument using product moment interrelation with the help of the SPSS application.The instrument is declared valid and feasible to be implemented in research if it fulfills rxy > rtable with a significance level of 5%.The reliability test aims to determine the degree of reliability or constancy of the research instrument.The analysis technique used in the reliability test uses Cronbach Alpha with the help of the SPSS application.The instrument is declared reliable if the degree of constancy is in the interval 0.61 -0.80 with the category of degree of constancy, namely high reliability.
Data analysis was carried out quantitatively using statistical tests, namely the independent sample t-test and the MANOVA test with the help of the SPSS application.Data analysis begins by carrying out an assumption test consisting of a normality test, homogeneity test, and linearity test.
This research was conducted to determine the effectiveness of using picture story book learning media in developing critical and creative thinking skills.Research activities began by analyzing the questionnaire with the aim of obtaining information related to the problems that students and teachers have in the learning process.Based on the need analysis questionnaire, students' critical and creative thinking skills are still low.This condition is indicated by students who are not active in learning.When students present their work, other students find it difficult to provide feedback related to the material presented.This happens because there is still a lack of understanding of students' concepts related to the material provided (Álvarez-Huerta et al., 2022;Ayçiçek, 2021).Atma et al. (2021) states that students' low understanding of concepts is due to several factors such as low learning motivation and the influence of the application of learning methods implemented by the teacher.The learning methods implemented by the teacher must be varied and able to facilitate the characteristics and abilities of elementary school students (Fitriyadi & Wuryandani, 2021;Nawangsari et al., 2022;Suryatin & Sugiman, 2019).One solution to this problem is to implement media in classroom learning.Based on the student response questionnaire, 53% of students strongly agreed if they studied with learning media that integrated images, text, and practice questions.Learning media based on images, text, and practice questions can develop students' curiosity and learning motivation (Dewi & Rukmini, 2019;Maryati et al., 2019;Sulthon et al., 2021).This student's curiosity and learning motivation are needed to develop critical and creative thinking skills (Facione, 2020;Gunawan & Suhardi, 2019).Therefore, researchers carry out learning that utilizes picture story book learning media to develop critical and creative thinking skills of fifth grade elementary school students.
Before the implementation of the research begins, the researcher first prepares research instruments and tests the validity and reliability of the instruments.Test the validity of the instrument includes a critical thinking skill test instrument and a creative thinking skills test instrument.The results of the validity test of the critical thinking skill test instrument are presented in Table 1.Based on Table 2, there are five creative thinking skill test items that meet valid criteria so that they can be used to measure the creative thinking skill of fifth grade elementary school students.After carrying out the validity test, then the instrument reliability test was carried out.Instrument reliability using Cronbach Alpha with the help of the SPSS application.The results of the instrument reliability test are presented in Table 3.

Instrument
Reliability Estimation Critical Thinking Skills 0.782 Creative Thinking Skills 0.611 Table 3 states that the estimated reliability of the test instruments for critical and creative thinking skills each scored 0.782 and 0.611 in the high reliability category.These results indicate that this test instrument can be used to measure critical and creative thinking skills.
After learning was carried out by utilizing the picture story book learning media, the research data were then analyzed to identify whether there was an increase in the critical and creative thinking skills of fifth grade elementary school students.The first step taken is to test the assumptions before and after the use of picture story book learning media in learning.Data from the normality test results before using the picture story book learning media are presented in Table 4 and Table 5. Tables 4 and 5 state that the data from the normality test results in the experimental and control classes with sig.< 0.05.These results indicate that the data comes from a normally distributed population.The next step is to test the homogeneity of the covariance matrix.The results of the covariance matrix homogeneity test are presented in Table 6 and Table 7.  6 and 7 state that the covariance matrices of the critical and creative thinking skills variables are homogeneous.The next step is to do a linearity test before using picture story book media.The results of the linearity test before using the picture story book media are shown in Table 8.Table 8 shows that the results of the linearity test in the experimental class obtained sig.0.512 > 0.05.These results state that the variables of critical and creative thinking skills fulfill the linearity requirements in the experimental class.Similar results were also obtained in the control class.The results of the linearity test in the control class obtained a sig.1.489 > 0.05, the variables of critical and creative thinking skills also fulfill the linearity requirements in the control class.
The next step is to test the MANOVA assumptions after using the picture story book learning media.This assumption test also includes the normality test, homogeneity test, and linearity test.The results of the normality test after using the picture story book learning media are shown in Tables 9 and  10.Tables 9 and 10 state that the data from the normality test results in the experimental and control classes with sig.< 0.05.These results indicate that the data comes from a normally distributed population.The next step is to test the homogeneity of the covariance matrix.The results of the covariance matrix homogeneity test after using the picture story book learning media are presented in Table 11 and Table 12 Tables 11 and 12 state that the covariance matrices of the critical and creative thinking skills variables are homogeneous.These results indicate that the variance of the pre-test and post-test data for the values of critical and creative thinking skills of fifth grade elementary school students is the same or the homogeneity of variance in all dependent variables is fulfilled.
The final stage of testing this assumption is to carry out a linearity test after using the picture story book media.The results of the linearity test after using the picture story book media are shown in Table 13.
Table 13 13, the significance obtained in the experimental class and control class is greater than 0.05.These results indicate that the variables of critical and creative thinking skills fulfill the linearity requirements in the experimental class and the control class.
The effectiveness of using picture story book learning media in developing critical and creative thinking skills was then analyzed using the MANOVA test.The MANOVA test results before using the picture story book media are presented in Table 14.H0 is accepted.Therefore, it can be concluded that the critical and creative thinking skills of fifth grade elementary school students do not have a significant difference in critical and creative thinking skills between fifth grade elementary school students who have participated in learning by utilizing picture story book learning media with does not use picture story book learning media.
After doing the learning by utilizing the picture story book learning media, the test results were analyzed again using the MANOVA test.The MANOVA test results after using the picture story book learning media are presented in Table 15.Therefore, it can be concluded that there is a significant difference in the critical and creative thinking skills of fifth grade elementary school students who take lessons using picture story book learning media and students who do not use picture story book learning media.These results state that the use of picture story book learning media can improve critical and creative thinking skills of fifth grade elementary school students in cluster IV Sintang District.
To see the difference in the average increase in the value of critical and creative thinking skills of students who take part in learning by using the picture story book learning media, an independent sample t-test is carried out.The results of the independent sample t-test for the variable critical thinking skills are shown in Table 16.Table 16 states that the sig.0.000 < 0.05.That is, H0 is rejected.Therefore, it can be concluded that students who take part in learning by using picture story book learning media have increased critical thinking skills that are superior to students who learn not to use picture story book learning media.Judging from the creative thinking skill variable, the results of the difference test on the increase in the creative thinking ability of fifth grade elementary school students are shown in Table 17.Based on Table 17, the sig.obtained by 0.021 <0.05.That is, H0 is rejected.Therefore, it can be concluded that students who take lessons using picture story book learning media have an increased ability to think creatively which is superior to students who learn not to use picture story book learning media.

Conclusion
Learning media picture story book is very necessary in learning in class V elementary school.This statement is proven by the significance results which show that the use of picture story book learning media is effective for developing critical thinking skills and creative thinking abilities of fifth grade elementary school students.Based on Pillai's Trace value, Wilks' Lambda value, Hotelling's Trace value, and Roy's Largest Root value shows the Sig value. of 0.000 which means Sig.< 0.05.These results indicate that there is a significant difference in the critical and creative thinking skills of students who take pictures story book learning media and those who do not use picture story book learning media.Therefore, it can be concluded that there is a significant increase related to the critical and creative thinking skills of students who learn to use the picture story book learning media.
