Assessment is a technique for evaluating student learning outcomes and deciding whether or not the learning objectives have been achieved. This study aims to determine the validity, reliability, and difficulty level of the tested items. The data collection technique used a documentation technique in the form of an answer sheet for the odd semester final exam for the 2021/2022 academic year for class XI at SMAS Al-Amjad Medan with a total of 222 respondents, and the form of the question was 45 multiple-choice questions (dichotomies) with five categories of answers. The Rasch model is used to obtain fit items. This analysis was carried out with the help of Winsteps software version 3.7.3. Based on the results of the analysis of the results of the item analysis using the Rasch model, the following conclusions can be drawn: in terms of validity, the questions consist of 86,67% valid and 13,33% invalid; Cronbach's alpha value of 0,95 in the very good category, the Person Reliability value is 0,93, which is included in the excellent category; the Item Reliability value is 0,95 in the special category; the distribution of the difficulty level of the item items is by the rules for making questions because 8 items (17,78%) are in the very difficult category, 9 items are about (20%) are in the difficult category, 23 items are about (51,11%) are in the easy category and 5 items (11,11%) in the very easy category.

This study aims to determine students' learning difficulties in chemistry by using zoom in achieving cognitive, sociological and psychological aspects and to further examine the difficulties faced by students. Data collection using questionnaires and tests, then using the K-Means Cluster data analysis technique, with three clusters (groups) followed by crosstab and graph analysis, using SPSS IBM 22 and followed by the RASH model. the results obtained are that (a) cognitive aspects in the form of student thinking, followed by sociological aspects and psychological aspects related to students' internal factors (b) cognitive results are tested more deeply with the Expended Score Graph. The ICC is in accordance with the RASH Model, the difficult questions to work on are questions 10 and 13 are in the analysis (C4), the Outfit MNSQ value is between 0.5-0.15 and then from the Probability graph of Student Cognitive Ability is well distributed, thus the difficulty in the cognitive aspect lies in the questions presented. These results are very useful for identifying students' cognitive limitations in chemistry learning. Thus, from the results, it is explained that cognitive is the main difficulty, with the RASCH test it is known that the level of difficulty is at the analysis.

Every student is required to master science literacy in social life because this literacy is related to the ability of students to relate issues about science and their ideas as citizens. The logical influence of the demands of teacher professionalism in the presentation of chemistry learning is the teacher's ability to create the right learning strategy in accordance with the problems faced in the world of education. One of the things that can be done in solving the problem in question is to transfer the old learning method with the new one. This study aims to determine the improvement of HOTS literacy by integrating the PjBL model with the Crossword Puzzle media on the Reaction Rate material in class XI SMA and to describe the most developed aspects of HOTS literacy. This research is a Quantitative Descriptive research using an experimental method with a One-Group Pretest-Posttest Design design. The results showed that students' HOTS literacy ability increased through learning with the PjBL model with Crossword media, this was proven through a t-test that obtained a value tcount > ttable (7.152 > 2,03452) with an N-gain value of 0.7079 (70.79%).

Science literacy in social life is a very important competence for students as it relates to their ability to link problems in science with their perspective as citizens. One of the logical consequences of the need for teacher professionalism in the presentation of chemistry learning is the teacher's ability to create the right learning strategies that fit the problems facing today's education world. The transfer of old learning methods to new ones is one way to solve the problem. The aim of this study is to find out whether the increase in HOTS literacy occurs when the PBL model is integrated with the iSpring Presenter media on the Reaction Speed material in class XI SMA. The research will also explain the most evolving HOTS element of literacy. This study is a Quantitative Descriptive Study using experimental methods with One-Group Pretest-Posttest Design. The results of the study showed that the literacy ability of HOTS students improved through learning with the PBL model with iSPring Presenter media, this was demonstrated through the t test obtained thitung values > tables (10,55 > 2,032245) with N-gain values of 0.7639 (76.39%).
