INTRODUCTION
Education creates an environment and learning process that allows students to actively develop their potential, including mental strength, self-discipline, individuality, intelligence, character, and skills needed for themselves, society, state, and nation [1]. Educational goals can be categorized into three main domains, namely the cognitive domain, affective domain, and psychomotor domain. Indonesia has now introduced the learning independence curriculum. It is an improvement from the previous curriculum to enhance learning, regulated in Permendikbudristek No.2 Number 56 of 2022 [2]. Learning outcomes are an indicator of the expected success of education.
The development of learning outcomes has a vital role in the learning process. Learning outcomes can be used as indicators to measure students' suitability level based on evaluations conducted through tests [3]. Substantially, learning outcomes involve changes in behavior that cover various aspects [1].
Chemistry is a science group subject at the Senior High School/Madrasah Aliyah level, included in the independent learning curriculum. One of the learning outcomes of chemistry is using acid-base concepts in everyday life, including acid-base titration material [4]. An acid-base titration is also taught to grade XI high school students every semester. The material about acid-base titration is abstract and complex for most students [5]. This material is considered difficult by students, especially in determining the concentration of two-valence acids, the concentration of monovalent acids, and the type of titration based on the acid-base titration curve [5].
Based on the results of preliminary studies at SMA Negeri 1 Menganti Gresik, out of a total of 36 students, 55.56% considered acid-base titration material quite complex, 30.56% difficult, and 5.56% found it very difficult. The remaining 8.33% of students do not think acid-base titration material is involved. The results of the preliminary study also showed that 72.2% of 36 students who studied chemistry did not use a particular learning method. It is closely related to the learning methods used in the learning process. Poorly structured learning methods can lead to unachievable results. Therefore, it is necessary to teach the correct learning methods to students that are planned and easy to implement [6]. Educators' assessment approach helps students find the right way of learning for them. Therefore, it is necessary to have an assessment approach that helps motivate students to learn. In general, the assessment approach educators use is limited to summative assessment [7] and focuses only on the end-of-learning test. Based on the above, there needs to be a learning demand emphasizing post-learning feedback, namely review for learning evaluation.
Assessment for learning involves collecting and interpreting evidence about students' learning outcomes to assess the level of students' learning outcomes and identify areas where further support is needed and most appropriate. It is an ongoing evaluation process to help them succeed [8]. The quality of learning assessment used by educators can significantly impact the process and achievement of student learning outcomes. Students' performance and learning progress is revealed through assessment for learning, where students' performance on various tasks is assessed over a semester [9]. Feedback implementing afl is vital for educators to provide feedback on every task students do [10]. The aim is to improve students' learning outcomes and monitor the achievement of learning objectives by providing regular feedback.
In the 21st century, ensuring students are motivated to learn and innovate using information technology and media in the educational environment [11]. It is due to the ease of information dissemination, access, and vast communication opportunities. Therefore, the use of technology is crucial in this modern era to meet the needs of students during the learning process. For example, using Electronic Student Worksheets as a learning resource [11].
Electronic Student Worksheets is a student work guide written in electronic format to facilitate understanding of learning materials [12]. This guide can be accessed from computers, notebooks, and smartphones. Electronic Student Worksheets are created using the Zine web application. Heyzine is a web-based application that makes flipbook media in HTML format that can be accessed from various devices such as Android, iPhone, tablet, and PC [13].
According to research by [14], Student Worksheets not only function as a task that students must complete but also as a learning approach that helps understand concepts. Therefore, Electronic Student Worksheets can be combined with the assessment for the learning approach. Adopting this approach allows Electronic Student Worksheets to influence the assessment system used during the learning process. Some studies show that learning based on the assessment for learning approach can improve learning effectiveness. For example, [15] showed that applying afl assessment-based learning can improve students' learning outcomes on chemical equilibrium materials. Another study by [16] also found that assessment for learning-based learning effectively enhances students' learning outcomes, especially for reaction rate materials.
Based on the results of the analysis above, in improving the quality of learning, especially in the field of chemistry, the researchers are interested in conducting research with the title "Development of Assessment for Learning-Oriented Electronic Student Worksheets to Improve Student Learning Outcomes on Acid-Base Titration Material."

RESEARCH METHODS
This study uses the R&D research and development method, which refers to the Borg and Gall research and development model. The Research and Development (R&D) method produces certain products and tests their validity, practicality, and effectiveness [17]. This research was only limited to product trials. The study was conducted in May 2023 within two weeks, with the research subjects being students in class XI-2 in the 2022/2023 school year. The data collection techniques used were questionnaires, observation, and test methods. Data results were obtained from the effects of validity, practicality, and effectiveness in the form of quantitative data.
Validation of the Electronic Student Worksheet includes content and construct validity conducted by three validators with quantitative descriptive method. Validators will provide an assessment score of 1-5 on the validation sheet. The data obtained is then converted based on the Likert scale in the following The assessment of each aspect by the validator is declared valid or highly valid if it has a mode score ≥ 4. If there are aspects that do not meet the valid requirements, it is necessary to make improvements (revisions) and revalidation until they reach the specified criteria [19].
Practicality is also measured in addition to measuring validity [20]. The practicality of the Electronic Student Worksheet can be known from the results of the students' response questionnaire and observation of students' activities as supporting data. Data on the results of the learner response questionnaire is obtained based on calculations using the Guttman scale score in the following table: The data obtained was calculated using the formula below: The percentage of the results of the student response questionnaire is then interpreted according to the categories listed in the following table:  [21].
Analysis of student activity observation data during the learning process was obtained using the student activity sheet. The data was analyzed using the following formula: % student activity = ∑ frequency of student activities that appear ∑ frequency of overall student activity × 100% Students' activities are declared to be well implemented and support the practicality of the application of the developed Electronic Student Worksheets if the percentage of relevant student activities is more excellent than irrelevant student activities by ≥85%.
Feasibility is also measured by effectiveness. The effectiveness of Electronic Student Worksheets can be seen from the improvement of each student's pretest and posttest results. The pretest and posttest score data obtained by each student is then analyzed to determine the value using the following equation: value = ∑ score obtained ∑ maximum score × 100 Learning outcomes can be assessed using a discrete assessment with a scale of 0-100. Students are said to be complete if they have reached the KKM (Minimum Completeness Criteria) value set by the school, which is ≥ 75.
The improvement in learning outcomes after applying the assessment for learning-oriented Electronic Student Worksheets was analyzed with the N-gain test to determine the difference in scores between the pretest and posttest after using the Electronic Student Worksheet developed with the following equation: < g > = posttest score − pretest score maximum score − pretest score The calculation results obtained are then converted according to the gain score level criteria in the following table:

Effectiveness
The effectiveness of Electronic Student Worksheets can be seen from the increase in pretest and posttest results for each student. The students' learning test questions are multiple-choice questions totaling 6 with 5 answer options. The cognitive domains researchers use in making questions are C3 (application) and C4 (analysis). In the implementation of product trials, a pretest was conducted before being given treatment by applying the developed Electronic Student Worksheets and posttest two times. Students are declared complete if they have obtained a score of ≥75.
The results of increasing the N-gain value of each student are different. The improvement in learning outcomes is likely successful if the N-gain obtained is in the high or medium criteria. The results of the percentage of students' N-gain are in the following figure: Figure 1. Percentage of N-Gain Based on the picture above, there are 2 N-gain scores, namely Pretest-Posttest 1 and Posttest 1-Posttest 2. In the Pretest-Posttest 1 N-gain score, 1 student obtained N-gain in the low criteria with a percentage of 6%. In contrast, as many as 15 students obtained N-gain in the medium criteria with a percentage of 83% and as many as 2 students obtained N-gain in the high criteria with a percentage of 11%. Then in the Posttest 1-Posttest 2 N-gain score, there were no students who obtained N-gain in the low criteria so that the percentage was 0%, then as many as 2 students obtained N-gain in the medium criteria with a percentage of 11%, and as many as 16 students obtained N-gain in the high criteria with a percentage of 89%. Students learning outcomes have increased by obtaining an average N-gain pretest-posttest 1 value of 0.53 on medium criteria and an average N-gain posttest 1-posttest 2 value of 0.88 on high criteria. When summed up, The percentage of students in high and medium criteria is 94% at the first meeting. In the second meeting, the percentage of students who were in the high and medium criteria, when summed up, increased to 100%.
