Developing nationalism character-based children ' s literature module to increase Islamic elementary school students ' critical thinking

This study aims at producing a literature module of children based on nationalism character to improve the critical thinking ability of fourth grade students MIN Boyolali, and measuring the effectiveness of the module use in classroom toward critical thinking ability of fourth grade students MIN Boyolali. Set within the research and development type, this study adapts 10 (ten) stages of development procedure as formulated by Borg and Gall (1983). The subjects of the research were students and teachers of grade IV MIN Boyolali. Data collection was conducted through interview and observation, product validation, teacher and student response questionnaire, and performance of pre-test and post-test—which was analyzed using independent sample t-test. Meanwhile, product effectiveness was tested through quasi experiment. The result of the research showed that the module was categorized as ―fit‖ by material and language expert; while the media expert categorized it as "very fit". In the other hand, teacher and student responses to the use of learning module were categorized as "excellent". Further, the output of the independent sample t test showed that the p value (0.000) was less than the 0.05 significance level (p≤0.05), indicating that the module was effective to improve students' critical thinking skills.


INTRODUCTION
Indonesia as a developing country has many problems faced.For example, the problems faced today are terrorism, radicalism, and degradation of the character of society, and all of those problems can be traced back to the roots of education.The type and content of education greatly affects the students' thinking culture which of course will also influence them as adults (Schnabel, 2018).The demoralization phenomenon that is increasingly massive in the world of education can be easily found.Starting from the finding of textbooks for elementary school children (SD) containing inappropriate content until the case of an elementary school child impregnating a junior high school student (Widodo, 2018).It is the evident that increasing participation of education has not been fully followed by the increase of character and noble attitude that can build a strong shape of the nation.Character education has an important role in character building efforts in a broad sense involving related ministries, society, schools and parents to support the realization of a nation civilization which is superior and noble.
The phenomenon of weakening of such a character is very alarming.Lickona (1991) reveals that there are ten signs of the times to watch out for because if these signs already exist, it means that a nation is heading for the brink of destruction.Those signs are: (1) increasing violence among adolescents, (2) the use of worsening language and words, (3) strong peer group influence in violence, (4) increasing self-destructive behavior, such as the use of drugs, alcohol, and free sex behavior (5) the blurring between the good and bad moral norms, (6) decrease in work ethic, (7) the low respect toward parents and teachers, (8) the low responsibility of individuals and citizens, (9) increase of dishonesty, (10) the sense of mutual suspicion and hatred against others.The same symptoms can be found as presented by Lickona above with the conditions present in the elementary school at this time.Behaviors of disrespect of elementary students to parents and teachers, cheating or cheating on exams, bullying children, and their familiarity with sarcasm words and cigarette can be found easily; although this is not an attempt to generalize the character of all elementary students.
One way that can be used to shape character is through the learning of children's literature in elementary school.Students who study literature can learn to understand their friends, learn empathy between friends, and can understand the moral of an event narrated through characterization in children's literature (Tomlison & Brown, 2002: 4).
Supporting that opinion, Saracho and Spodek (2010: 401) also reinforces that children's literature helps students to connect the emotions through aesthetic experiences while engaging in the story.
Children's literature in elementary school cannot be separated from Indonesian Language subject in elementary school.This close linkage is due to the fact that the teaching of children's literature has been delivered in a limited way only with the portion of 10% (Wibowo, 2013: 22).Such expressed views are in contrast to the existence of Indonesian language in the integrative thematic curriculum 2013, which provides an advantage to children's literature learning since its materials delivered through Indonesian language get more opportunities to be taught by linking them to other subjects such as social studies, mathematics, and science.
According to Zuchdi (2009), the activities of using language which is in the domain of Bahasa Indonesia, including listening, reading, speaking, and writing, other linguistic forms learned, as well as literary appreciation, are integrated comprehensively and are incorporated into the themes which also cover the target values to be developed.This implies that the use of children's literature can also be related to subjects other than Bahasa Indonesia, so that the teaching of characters through children's literature gets the widest possible opportunity.However, learning practices that occur in the classroom, teachers rarely give the content of the character value of the subject matter that is delivered through the children's literature.
The significance of children's literature in learning is not only limited to its ability as a media to instill characters, but more than that, it also contributes significantly to the cognitive development of students as it contains not only personal value, but also academic one (Tomlison & Brown, 2002: 3-8).Regarding the function of children's literature in terms of cognitive enhancement, Saxby (1991: 8) states that it provides hardknowledge and soft-knowledge simultaneously.Hard-knowledge in literature is connected to fact and data while soft-knowledge is related to human heart, both of which cannot be found in the laboratory but through life experiences.Such a life experience is expressed metaphorically in children's literature.
Further, Chen (2012: 89) conveyed that the literature of children can also be used to improve students' thinking ability up to the stage of critical thinking.Critical thinking appears as students' response to what they read, especially in the form of literature which is metaphorical in nature and full of logic of causality.Children can also criticize it by guessing, finding evidence, reasoning, finding a way out of the difficulties faced by the character in the story, including predicting how the story will be solved.However, such a significance of children's literature which contributes to the development of students is not fully understood by teachers.
Teachers can use children's literature as a medium to instill character and critical thinking skills of elementary school students in the process of daily learning activities.They can employ literature-based materials to be implemented in teaching and learning.However, in contrast, 2013-curriculum-teachers mostly use teaching materials in the form of textbooks issued by Education and Culture Ministry which are still lack of the content on children's literature.
Basically, teaching materials have various types, one of which is printed material, included in module-type.Compared to other types, the module has superiority, that is, it only contains some primary subject matter, is more user-interactive, and can be completed according to the level of each student's ability (Prastowo, 2013).For that case, module is considered appropriate to be developed as a children's literature-teaching material.
Based on the documentation study conducted on teaching materials used by fourth grade students of MIN Boyolali, students use textbooks for learning instead of module-type material.Specifically, the book discussing theme 8 (Daerah Tempat Tinggalku/My Living Place) subtheme 3 (Aku Bangga dengan Daerah Tempat Tinggalku/I am Proud of My Living Place) has connection between basic competence of the subject, yet its literary content is not correlated with Boyolali area, in which most stories only contain information outside Boyolali area.In fact, the theme and subtheme used as a bound material is the students' area, i.e.Boyolali.
While based on interviews in December 2016 with a fourth grade teacher (AM), it can be concluded that the learning activity conducted at the moment did not fully focus on the efforts to increase critical thinking.
Learning taking place was more of in the level of remembering and understanding.Furhter, when presented a story, the students were only required to understand the story which is reflected through their quality in answering questions.Whereas, teachers could have improved students' critical thinking skills using materials that require students to think critically; those were the material that could be analyzed, synthesized, discussed and proven (Shirkani and Fahim, 2010).Such criteria can be obtained through children's literature.

METHODS
Applying research & development method, this study used the findings of the research to design a module that were systematically tested and evaluated to create an effective and efficient product scientifically (Gall & Borg, 2007: 589) 2) Need analysis through interviewing & observing the teacher as well as analysis of teaching materials to seek the weaknesses of learning process undertaken by the teacher and to find solutions required by the teacher.From these stages, it was found that a learning module that covers character and critical thinking instilment-based materials was required; (3) a preliminary module was then composed to be validated by the media expert and the material & language expert to obtain suggestions or feedbacks for improving the quality of the module; (4) moving to the stage of preliminary field testing, the revised module was tested, with a class IV C teacher and three students from the same class as the subjects.
The purpose of this stage was to gain information regarding teacher and students responses, to be used as consideration in improving the module.
Based on the data gained from the previous stage, the researcher conducts the next steps of: (5) main product revision, (6) main field testing, (7) operational product revision, (8) operational field testing, (9) final product revision and (10) dissemination and implementation.
In the main product revision stage, the data obtained was used to revise the product (step 5).The revised module was again brought to the experts to get input from the media expert and the material & language experts.After the input from the experts were applied to the module, the next step was to test the product in a broader scale that is main field testing.The subjects were the teacher, and other 6 students of grade IV C which were different from the three students from main field testing stage.The data obtained, in the form of teacher and students response were then used as guidelines to revise the module, which later would be tested in the operational field testing phase.In operational field testing, quasi experimental method was implemented to monitor the effectiveness of the module in improving the ability to think critically.Therefore, two classes were given different treatment, as shown in Table 1.Data obtained from this stage, in the form of student scores, was then measured using homogeneity test and t-test.The next step was final product revision, which aimed at producing a module that was feasible and effective for learning.The data gained from post-test and pre-test of the students, on the other hand, was tested using t-test.This analysis was conducted to determine whether there was any difference in students' critical thinking achievement when using conventional learning (control class) compared to that of using module (experimental class).

Material and language expert's assessment
The module was validated by the material and language expert based on the conformity of the material description with the core competence and basic competence, the accuracy of the material, the learning support material, the suitability of the learner's development level, the level of communicativeness of the language used, and the structure & unity of ideas.The results of the assessments are presented in Table 4.The table above shows that the average score given by material and language experts was 4.20.When referring to the scale-5 conversion table, the module was categorized into value B or good, which is between 3.40 and 4.21, and is above the minimum score (3.41) as described in the following graphic.

Furthermore, the scores of each subcomponent can be seen in Table 5.While based on the conformity of material description with core competence and basic competence, the accuracy of the material, as well as the learning support materials, the product is in category B (good).In terms of language, the structure and unity of ideas of the product are in the category A and communicativeness level of language is at level B.

Media expert's assessment
In terms of how media were attached, the module was assessed based on the feasibility of presentation that included presentation techniques, learning presentation, and presentation completeness.While from the aspect of fonts, the indicators scrutinized were related to module size design; cover layout; cover typography; contents layout; harmony, acceleration of understanding, and completeness of content layout; as well as illustration.

Picture 2. Results of children's literature module assessment by media expert
Table 6 shows the average score of the media experts at 4.25.When referring to the scale 5 conversion table, the product gets a very decent predicate (A), where the value is above 4.21, and is above the minimum score of 3.41.This is illustrated in Picture 2. The results of average score for each aspect can be seen in Table 7.  Table 7 shows that in terms of media, aspect of graphics is superior over that of the feasibility of the presentation with the score of 4.70 and 4.15 respectively.This indicates that the former is in category A or excellent while the later is at the level B, or good.

Students' response
Having validated by the experts, the module was then tested to the students to gain their responses regarding its usability for learning.The two main aspects examined were to what extent the module could encourage independent learning and how friendly it was to the users.Self Instruction The material presented in sequence to be understood easily

B
The clarity of instructions in each activit The suitability of time allotment.
The module composition eases students to understand materials independently with measured guidance.

User Friendly
Interesting module display 4,3 A The stories included in the material completed by attractive pictures.The clarity of the passage in the material and the activity.The language used is straightforward and communicative.

Total score 8,3 A
The overall score above shows that the average total score was 8.3 and therefore was in category A or "excellent".This means that based on the learners' opinion, the module was very interesting and encouraged them to study independently.While in terms of assessment per aspect, self instruction was in category B or "Good".On the aspect of user friendly, the score obtained was 4.3 with category A or "Excellent".

Teacher's response
Based on the response of the teacher toward the module developed, the data obtained is presented in Table 9.The results of the average total score above (4.8)indicates that based on the teacher's response in the questionnaire, the learning module was "excellent" and feasible to be used in operational field test.Specifically, in both aspects, the score were categorized with predicate A. Further, the feedback from the teacher was just to be consistent in designing the competence mapping between one learning session and the others.

Module's effectiveness test
The t-test was performed to determine whether there was any difference in critical thinking ability between control and experimental class.Firstly, normality and homogeneity tests were used as a prerequisite for analysis.
The results are presented as follows.In other words, Ho was accepted or the data has a normal distribution.When homogeneity test was performed, the p value obtained in the pretest data was 0.325.This means that the p value was greater than significance level (Sig> 0.05).Thus, Ho was accepted.While in the homogeneity test of posttest data, the p value was 0.13, which shows that Sig> 0.05 i.e. the significance value is greater than the specified significance level.Hence, it can be concluded both data is homogeneous.
The next test performed after the data was proven normal and homogenous was independent sample t test using SPSS 16.0 for Windows, which aimed to see whether there was any difference in critical thinking skills between students from control class and experimental class.

The proposed hypothesis formulation was:
H 0 : There is no significant difference in critical thinking skills between students who perform the lesson using children's literature-based module and those who don't.H i : There is significant difference in the ability of critical thinking between students who perform the lesson using children's literature-based module and those who don't.
The result of the t-test is described in the Table 11.The result of independent t-test shows that the variance of critical thinking ability ratio between the control and experiment class was in the value of 0.000.When compared with the significance level of 5% (α = 0.05), it can be drawn that the p value was less than 0.05 (p ≤ 0.05 / 0.000 ≤ 0.05).
This proves that there was significant difference between the control class and the experimental class, in which the students using the nationalism character-based module (in experimental class) for six times of learning process outperformed critical thinking ability compared to those of who did not use the module (in control class).
After going through the independent sample t-test, in other words, the product of this research and development study, in the form of children's literature module, was considered effective to improve student's thinking ability.The effectiveness of the product could of course be achieved after going through and meeting a series of development stages so as to produce a module that was worth-using.This was also proven by the P value Sig.level Information 0,000 Sig < 0,05 rejected data gained from the students' response who perceived that the module was excellent to be used for learning.That means students found it easy to use the module.It could be felt by them when they were able to learn at their own pace or when they found it familiar as it was interesting and systematic in terms of the design.This is corroborated by the opinion of Chengizhan (2008: 99) which states that "... is the modular instruction design that provides a flexible learning environment in its design, the active participation of students, and the opportunity for students to progress at their own rate and make their ownself assessment ".
In terms of the feasibility of the module in inculcating the character of nationalism through literature can be corroborated by the opinion of Logli (2015) who explains that the national identity is actually a feeling of a group towards the fundamental features that form the homeland or the same feeling of cultural similarity.In the other side, it is important to be understood that literature is a cultural product of a community system.This makes literature able to be used to instill character on the society, in this case the character of nationalism.
The effectiveness of this children's literature-based module in improving critical thinking skills can be seen based on the t-test result where p value (0,000) was less than determined significance level (p ≤ 0.05 / 0.000 ≤ 0.05).This is also confirmed Ellen's statement in Santrock (2011: 33) that the fundamental element in critical thinking is the attentive attitude in daily activities.In correlation that, the developed module has proven eligibility to attract students' attention to use it for learning, accompanied that is the dissemination of the research findings will be more useful if it can be adopted by the teacher, or even more i.e. by adopting the method of module development.
(3) Teachers should be able to enrich learning resources to be used by students in learning, for the reason that government-published textbooks are sometimes not in accordance with student environmental conditions.Therefore, it would be better for teachers to develop the module as another teaching material reference in order to encourage students' independent learning attitude in pursuing their needs.
Derived from the existing condition, this research focuses more on developing character-based children's literature module to increase critical thinking ability of fourth graders in MIN Boyolali on the theme of My Living Place subtheme I am Proud of My Living Place.This study is conducted as one of solutions to complete module need in MIN Boyolali and to foster good character in fourth grade students.
. Subjects in this study were students of class IV A, B, and C of MIN Boyolali.The subject of preliminary field testing consisted of 3 students of class IV C with high, moderate and low cognitive ability.Meanwhile, the main field testing comprised of different 6 students of grade IV C. For the operational field testing, class IV A was selected as the experimental group and class IV B as the control group.Those subjects were chosen using purposive sampling technique.The research stages were adapted from the design made by Borg & Gall i.e.: (1) & ( by self-awareness to learn step by step of what makes them interested during learning process.CONCLUSION The research and development (R & D) procedures developed and implemented are aimed at reducing the chances of failure and increasing the chances of successful study.However, along with the involvement of human element i.e. researcher in it, it will certainly experience certain level of limitations in the research conducted.The limitations in this study are as follows: (1) Limited material developed, this research only developed one sub theme due to the limited time in the study.Thus, the module generated could not closely embrace all the needs in the field.(2) The absence of empirical validation of the exercises used in measuring students' critical thinking skills.Validation employed was only restricted to that of the construct by the instrument expert.(3) The instilment of nationalism character through the developed module was only conducted in the scope of cognitive aspect.Meanwhile, the fundamental principle of character shaping is basically derived from a habit that is done repeatedly.For further research and the elementary school academic community, constructive suggestions are structured as follows: (1) innovation in learning can be continuously performed in the future by, one of many, developing modules with broader material coverage which are emphasized on fostering positive values or characters suited with learning needs -not limited to a mere single subtheme.(2) The school should facilitate improvement effort in the learning process, in the context of this study
