Astri Hapsari2 Department of English Language Education. Universitas Islam Indonesia. Indonesia 21322062@students. hapsari@uii. Abstract: Although writing self-efficacy is essential for the development of second/foreign language learnersAo writing skills, there are still limited studies on EFL writing self-efficacy among senior high school students in the Indonesian context. This study aims to test the correlation between studentsAo EFL writing self-efficacy and their performance in writing a procedure text in a senior high school. One hundred and sixty-three students agreed to participate in this correlational study with purposive The researchers used an Indonesian version of the Second Language Writing Self-Efficacy Scales by Teng et al. The result showed a significantly negative correlation . = -. between studentsAo self-confidence in writing and their actual writing performance, with a significance A value = . 257, which it is is greater than the significance level of CronbachAos alpha ( = 0. Therefore, the null hypothesis (H. is accepted that there is no significant correlation between writing self-efficacy and writing performance. As it is limited to students from one school in grade 11 and procedural text, future research needs to be conducted with more participants and diverse text types to enrich the discussion and explore factors that contribute more substantially to these text types.

EFL writing, procedure text, senior high school students, self-efficacy INTRODUCTION The Merdeka Curriculum . r Emancipated Curriculu. , which was first introduced in Indonesia in 2020 by the Minister of Education. Culture. Research, and Technology, has been widely implemented. To this day, the Merdeka Curriculum is now under the responsibility of the Minister of Primary and Secondary Education (Mendikdasme. led by Abdul MuAoti (Sabrina. Saputra. Lahfi, & Fadhil, 2. This curriculum aims to provide a more holistic approach to education, facilitating character development, creativity, and critical thinking, as well as academic achievement. The curriculum is also more inclusive, flexible, and responsive to each individual's needs, emphasizing a learner-centered approach and integrating technology into the learning process (Zidan & Qamariah, 2023. Krishnapatria, 2. , providing a variety of intracurricular learning opportunities, designed to optimize content so that every student has ample time to explore concepts and reinforce their skills (Ndari. Suyatno. Sukirman, & Mahmudah, 2. This curriculum enhances a learning environment that support studentsAo writing self-efficacy When students have freedom in learning related to writing and sufficient time to explore deeper into writing strategies, they tend to be more confident about their writing Writing, as a productive skill in English language learning, demands not only linguistic competence, such as mastery of vocabulary and grammar, but also critical thinking abilities, including the organization of ideas and the effective articulation of arguments in a clear and comprehensible manner (Korban. Jamiluddin. Budi, & Mertosono, 2. The difficulties they Maya Tri Astuti. Astri Hapsari experience can negatively impact their academic writing performance (Nurdianingsih. Fitriati. Astuti, & Rozi, 2. Several contributing factors influence these difficulties, including confusion about selecting appropriate vocabulary in the right situation (Korban et al. , 2. difficulties with expressing and organizing ideas, and a lack of grammatical knowledge (Harmawan. Pratama, & Fadilah, 2. , and writing anxiety (Nugroho & Ena, 2. , limited vocabulary range and inadequate grammatical understanding (Falihah. Rahmawati, & Baihaqi, 2. , as well as insufficient awareness of academic writing conventions in English (Pasaribu. Pasaribu. Siahaan, & Sitompul, 2. In research involving EFL secondary students. Hafizah et al. found that the students encountered difficulties in vocabulary, language use, and mechanics. These problems influence studentsAo writing self- efficacy, which also affects their performance. The struggle arises due to several factors, including the habit of using the mother tongue rather than the English language, limited academic writing knowledge, insufficient knowledge about the topic, and limited access to reference materials (Ho, 2. Therefore, studentsAo writing selfefficacy is necessary to overcome challenges because it directly influences motivation, strategy, and writing results (Pajares, 2. Besides that, writing self-efficacy can help students face challenges through several steps, such as lowering writing anxiety (Zhou. Wang, & Wang, 2. , increasing motivation and perseverance (Martono. Dian WP. Yulianto. Purwanta, & Dwiningrum, 2. , and enhancing writing qualities (Pajares, 2. Some challenges that appeared in studentsAo writing process when the researcher conducted the teaching internship were lack of grammar, limited vocabulary, and unorganized structure, for instance, confusion about choosing appropriate conjunctions. The EFL senior high school students were in grade 11. To overcome the challenges, the researcher made several efforts, such as asking students one by one and allowing them to open their smartphones for an important occasion, such as searching for references about conjunction words. Until the end of the meeting on procedural text, some students still have problems with grammar. Therefore, the researcher decided to conduct a study about the relationship between writing self-efficacy and writing performance. Writing self-efficacy refers to one's confidence in oneAos ability to succeed in English writing tasks (Hetthong & Teo, 2. Confidence in English writing affects how students view writing in general. it influences whether they will try to master or avoid writing tasks. If students believe they can complete a writing task, regardless of their writing ability, they are more likely to work harder to overcome challenges while practicing or completing the task. When faced with difficulties, self-efficacy encourages students to remain committed and continue trying different strategies until they complete the task. Therefore, writing performance is influenced by writing self-efficacy. Similarly, in other research, writing self-efficacy refers to studentsAo belief in their ability to complete writing assignments (Zhang & Zhang, 2. Pajares . stated that writing self-efficacy is also related to other aspects, specifically writing anxiety, grade goals, depth of processing, and expected outcomes. Writing self-efficacy was positively related to several motivational factors, including the perceived importance of writing, one's self-concept, confidence in self-regulation abilities, goals focused on engaging with tasks, and goals aimed at achieving high performance. Research by Hetthong and Teo . proved that writing self-efficacy plays a role in predicting students' writing Students with higher writing self-efficacy tend to be more motivated, persistent, and confident when facing writing challenges. Writing skills are one of the important aspects of the English subject. However, in the implementation, some of the students still faced challenges, including a lack of understanding about the structure, limited vocabulary, and a lack Prominent: Journal of English Studies Vol. 09 No. 01 January 2026 p-ISSN: 2621-024x. e-ISSN: 2621-0258 Website: https://jurnal. id/index. php/Pro of social function and linguistic characteristics of the text (Irawaty. Yunanada. Simalango. Simanullang, & Lubis, 2. Meanwhile, in the procedural text, students find the challenges, particularly focusing on the topic, choosing appropriate vocabulary, using conjunctions, using imperative sentences, the generic structure of paragraphs, and using punctuation (Tiyas & Kartikawati, 2. One of the factors that contributes to these challenges is studentsAo selfefficacy. This problem needs to get more attention because the difficulties that students experience negatively influence their writing performance. Therefore, it is important to identify the correlation between writing self-efficacy and writing performance to get clear information about the correlation, especially in procedural text. Husna. Setya, and Rohmah . conducted a study to investigate the relationship between writing self-efficacy and studentsAo performance in writing recount texts. The research involved 110 participants and utilized two primary instruments for data collection: the SelfEfficacy for the Writing Scale (SEWS), adapted from Bruning et al. , and a writing task requiring students to produce a recount text of at least 200 words within a 60-minute timeframe. To evaluate writing performance, the researchers employed the EFL Composition Profile, developed by Jacobs et al. , which assesses five components: content, organization, vocabulary, language use, and mechanics. The study concluded that there was no statistically significant relationship between students' self-perceived writing abilities and their actual writing outcomes in the recount task. In contrast. Rudiyanto . focused her investigation on the relationship between writing self-efficacy and performance in the context of descriptive texts. Her study involved a selected sample of 20 to 40 students from a larger group of 60 participants. Data were collected using the L2 Writer Self-Efficacy Scale (L2WSS) by Teng. Sun, & Xu . , which evaluates learnersAo confidence in writing based on their linguistic competence, classroom experiences, and learning strategies. To assess writing quality, she utilized the Level-Specific Checklist of Binary Choice Items, created by Lukycsi in collaboration with the Euroexam International team, comprising 34 evaluation items aligned with the Common European Framework of Reference (CEFR). Unlike the findings of Husna et al. AldinaAos study revealed that in writing descriptive texts, secondary students generally demonstrate a medium level of writing self-efficacy. This statement is supported by findings showing average scores ranging from 4 to 5. Several factors, such as the variety of text types, the writing assignment, and the scoring rubric, can be the reasons for the differences in findings between Husna. Setya, and Rohmah . and Aldina . While HusnaAos study focused on recount texts and used a traditional composition profile. Aldina examined descriptive texts using a CEFR-aligned checklist that offered a more comprehensive and context-specific evaluation. Additionally, the use of different self-efficacy scales - SEWS in HusnaAos study and L2WSS in AldinaAos - may have affected the results of the However. Yuda. Rasuki, and Fathurrochman . presented an alternative view, arguing that higher self-efficacy is associated with better writing performance and emphasizing the importance of developing self-efficacy in EFL learners to enhance their writing abilities. Yuda et al. utilizes a quantitative approach for data analysis. The students were asked to write a descriptive text and complete a self-efficacy questionnaire. The collected data were analyzed statistically to determine the relationship between their self-efficacy levels and writing ability scores Yuda et al. Previous studies on the correlation of writing self-efficacy and writing performance among high school students in the EFL context, particularly in Indonesia, focus on different types of text (Rudiyanto, 2022. Binnendyk. Patty, & Jamil, 2024. Hafizah Maya Tri Astuti. Astri Hapsari et al. , 2024. Yuda et al. , 2. Therefore, this research aims to complement and expand existing studies by focusing on Indonesian senior high school students and exploring the correlation between writing self-efficacy and writing performance, specifically in writing procedure text. The novelty offered in this research is that the students participated in this study have completed the module about writing procedure text with the theme financial This research has several limitations that should be acknowledged. First, the participants are limited to EFL students in a senior high school at Yogyakarta grade 11, who completed writing procedural text during the academic year 2024/2025. Therefore, this research probably cannot be generalized to wider populations. Second, this research only focuses on the correlation between writing self-efficacy and writing performance, specifically on procedure therefore, it does not represent students' writing abilities as a whole. The research was conducted based on the following formulation of the problem: What is the correlation between studentsAo writing self-efficacy and their writing performance? The primary objective of the study is to test and analyze the correlation between the writing self-efficacy of students and their writing performance at the end of the procedure text module. On empirical grounds, this study is important in contributing to a better understanding of the correlation between writing self-efficacy and writing performance in writing procedure text. On the practical ground, the findings of this research are expected to help teachers and students identify the challenges and improve studentsAo writing performance. RESEARCH METHOD Research Design This study was designed to analyze the correlation between writing self-efficacy and writing performance for EFL senior high school students in grade 11 who have already learned about procedure text. This study implements quantitative research with two variables: the independent variable (X) indicates writing self-efficacy, and the dependent variable (Y) indicates writing performance. This study is a correlational design, which involves gathering information from individuals about two or more variables, then analyzing whether there's a relationship between them. A correlation shows how closely the variables move together, either in the same direction, which means a positive correlation, or in opposite directions, which refers to a negative correlation (Ary. Jacobs. Sorensen, & Razavieh, 2. This concept is operationalized by using the Second Language Writer Self-Efficacy Scale (L2WSS) as a research instrument. The Second Language Writer Self-Efficacy Scale was developed by Teng et al. and utilized a 7-point Likert scale, with responses ranging from 1 . ot at all true of m. to 7 . ery true of m. This construct was represented through a series of written items, each reflecting a statement about how confident learners feel during the process of learning to This instrument has been previously used in a study by Aldina . , although with a different type of text. Meanwhile, the dependent variable (Y) is the studentsAo performance. To assess studentsAo writing performance, the study used the scoring rubric employed by the teacher at the school, which the teacher had previously validated. The rubric consists of four assessment criteria: content, organization of ideas, language use, and mechanics. The rubric assessment consists of content, organization, language, and mechanics. The table below shows how the rubric assessment is used to assess studentsAo writing performance based on the English teacherAos recommendation and consistent with the theory of writing performance by Weigle .

The 11th grade has a population of 252 students, and 163 students agreed to participate in the study. Therefore, this research adopted purposive sampling, because all the participants were purposefully chosen as students who had been assessed on the learning outcomes in procedure text, and the researcher was already teaching grade 11 in this school at the teaching internship.

The first is the Second Language Writer Self-Efficacy Scale (L2WSS), which measures the level of studentsAo writing self- efficacy. The second one utilizes scoring rubrics to assess studentsAo performance in writing procedural text. Writing Self-Efficacy To measure studentsAo self-efficacy levels, a set of questionnaires was distributed directly to the students by the researcher through a Google Form. Participants accessed the form via a provided link or QR code, which included student identification, instructions, and 20-item questionnaires. The questionnaire, named the Second Language Writer Self-Efficacy Scale (L2WSS), was initially developed by Teng et al. , was modified by the researcher to suit the studyAos context. The questionnaire aimed to capture studentsAo perceptions and beliefs regarding their writing abilities. The questionnaire is structured around three key dimensions of writing self-efficacy. It consists of seven items that assess linguistic self-efficacy, which refers to studentsAo confidence in their language-related skills. Another six items focus on self-regulatory efficacy, measuring studentsAo perceived ability to manage and control their writing processes effectively. The remaining seven items address performance self-efficacy, which reflects studentsAo beliefs in their ability to produce successful writing outcomes.

Self-Regulatory Efficacy Performance Self-Efficacy Students were asked to respond to each statement using a seven-point Likert scale, as introduced by Teng et al. The Likert scale served as a tool to evaluate the writing self-efficacy of eleventh-grade Senior High School students at Yogyakarta. The 7-point Likert scale was divided into intervals reflecting relatively equal differences in responses, as illustrated in the table below. Maya Tri Astuti. Astri Hapsari Scale Table 3. 6 7-point Likert scale Description Not at all true of me Mostly not true of me Somewhat not true of me Neutral / Neither true nor untrue of me Somewhat true of me Mostly true of me Very true of me Validity refers to how accurately an assessment tool measures the specific concept it is designed to measure (Obilor & Miwari, 2. Validity of the instrument of writing self-efficacy was carried out by checking the validity value of the original instrument by Teng et al. This instrument has also been used in a previous study by Aldina . in the context of high school learning, but with different types of text. The researcher conducted two types of validity test of instrument. The first one is content validity, which means the researcher translated the instrument into Indonesian to suit the Indonesian context and the various English language abilities of students. During translated the instrument, the researcher consulted with the undergraduate thesis supervisor to make sure that the translated sentences do not changes the meaning. The second one is criteria validity, and the instrument was tested using Pearson's Correlation. A whole set of items is valid as proved by the value of PearsonAos Correlation is greater than the R-Table. Research by Taber . explained that CronbachAos Alpha is classified into 17 categories of reliability, ranging from low to excellent. In these classifications. CronbachAos Alpha, with a value of . 977, is included in the category of excellent. Writing Performance To assess studentsAo performance, the students are given various assignments, with the last one being a writing procedure text. The assignment is given once at the end of the lesson. After completing the assignment, it is submitted and assessed using the scoring rubric recommended by the English teacher at that school. The scoring rubric has four aspects that will be assessed, such as content, organization of ideas, language use, and mechanics that which have has its scoring provisions for each aspect. This instrument has been validated by experts, including the supervisor who supervised the teaching practice at the school being studied and the English teacher from the school being studied. Additionally, the rubric assessment also arranged based on writing performance by Weigle . The rubric assessment is shown in the following table.

Then, tested using the ShapiroWilk test and the Kolmogorov-Smirnov. The Kolmogorov-Smirnov test is used for comparing two samples (Yang & Berdine, 2. In this normality test, data is considered not normally distributed if the p-value is less than the chosen alpha level. In contrast, if the p-value is greater than the chosen alpha, then the data is normally distributed, considering that = 0. Meanwhile, in this research. Writing Performance showed that the p-value is at < 0. 001 and the p-value of writing self-efficacy is at 0. 050, which is tested by Kolmogorov-Smirnov and 035 by Shapiro-Wilk. Table 4. 1 Normality Test of Kolmogorov-Smirnov and Shapiro-Wilk Kolmogorov-Smirnov Shapiro-Wilk Statistic Sig. Statistic Mean Writing SelfEfficacy Writing Performance Sig. Even though the data was not normally distributed, the researcher tried to conduct a linear test. The linearity test was conducted by regression analysis using Jamovi.

In conclusion, there is no significant correlation between writing self-efficacy and writing performance in the context of procedural text type. Discussion The purpose of this research is to test the correlation between writing self-efficacy and writing performance in grade 11 senior high school students. The result of the study is not similar to the previous studies, which shows a significant correlation between writing selfefficacy and writing performance (Binnendyk et al. , 2024. Yuda et al. , 2. The differences in results can be caused by several factors, such as: mismatching between studentsAo belief about writing and their writing skills, diverse classroom instructions experienced by the students to complete the writing module, possibility inter-rater reliability in scoring studentsAo performance . ecause some of the students were not scored by the first researche. However, this study is in line with another study by Rudiyanto . and Husna. Setya, and Rohmah . found no significant correlation between writing self-efficacy and writing Prominent: Journal of English Studies Vol. 09 No. 01 January 2026 p-ISSN: 2621-024x. e-ISSN: 2621-0258 Website: https://jurnal. id/index. php/Pro In Aldina's study, she did not explain the factors that caused the insignificance of her research. However. Aldina mentioned limitations and several factors that probably influenced her research results, such as participants who only focused on EFL, especially Indonesian high school students, gender factors. IQ, and additional variables. Meanwhile. Husna. Setya, and Rohmah . stated that one of the factors that influences the differences in research findings is the difference in writing strategies between students, the rubric assessment used, the participants, and the object being measured. The better writing performance is produced by appropriate writing strategies. If the students have better writing results, it will increase students' writing self-efficacy. The successful experiences in writing that students have had are one source of student self-efficacy. Nevertheless, this study is not about writing strategies therefore, it canAot be the same measurement as Husna's. CONCLUSION The purpose of this study was to test and analyze the correlation between writing selfefficacy and writing performance in grade 11 of EFL senior high school in Yogyakarta. A total of 163 students agreed to participate. The measurement of L2 Writer Self-Efficacy Scale (L2WSS) revealed that the profile of students' writing self-efficacy from the highest to the lowest mean score is: self-regulated efficacy, performance self-efficacy, and linguistic selfefficacy. The findings of the research indicate that the correlation coefficient is: rxy= -. 089 and the pvalue = . 257 that has been measured by SpearmanAos Rho. It means that there is no significant correlation between studentsAo writing self-efficacy and their writing performance in this research. There are several limitations in this study. One of them is the type of text used, which is a procedural text, so the findings cannot be generalized to other types of texts. addition, the participants in this study were English learners in an EFL country at the senior high school level. Because of that, the results might be different if the participants were from other groups, especially from EFL learners in different countries. In addition, the researcher suggests that the next study will provide more discussion on the factor that causes an insignificant correlation between writing self-efficacy and writing performance.
