This study aims to conduct a critical study of the teaching materials for Islamic Religious Education and Character Building (PABP), specifically on the material "Avoiding Backbiting and Carrying Out Tabayun" used in class VII of SMPIT Takhassus Al-Qur'an Ashabiq. The focus of the study in this study covers several important aspects, namely learning objectives, the material delivered, the learning methods and models applied, evaluation of learning outcomes, and sources and references for teaching materials used by teachers and students. The approach used in this study is descriptive qualitative with data collection techniques through document studies of teaching materials, observations of the learning process in the classroom, interviews with teachers and students, and data validation is carried out through expert audits to ensure the accuracy of the findings. The results show that the teaching materials used have referred to the principles of the Independent Curriculum and the Pancasila Student Profile, which emphasize the development of character and student competencies as a whole. However, several significant weaknesses were found, especially in terms of integration between learning objectives with learning activities and evaluations carried out. Learning materials are structured in a normative and idealistic manner, but they do not adequately accommodate students' real-life contexts, particularly in facing the challenges of today's digital era, which significantly impact how they understand and internalize religious values. Learning evaluation is still dominated by cognitive measures such as written tests and conceptual understanding, while the attitudinal and skill dimensions, which are crucial for character education, have not been optimally measured. Furthermore, the learning resources used are quite limited, relying solely on textbooks and student worksheets (LKS), without any support from contemporary literature or digital media that could enrich the learning process and make it more engaging and relevant to today's students.

This study aims to observe the phases of mitosis in the meristem cells of shallot roots (Allium cepa) through microscopic observation as part of the Cell Biology learning model. Mitosis is an important part of the cell cycle that plays a role in growth, tissue repair, and asexual reproduction in organisms. A deep understanding of the mitosis process is an important foundation in various branches of biology, including genetics, biotechnology, and histology. Shallot roots were chosen because they have actively dividing meristem tissue at the root tip,as well as a large and transparent cell structure that facilitates the staining and observation process. Preparation was carried out by soaking the onion roots in a solution of acetic acid and alcohol for fixation,then staining with acetocarmine acid so that the chromosomes are clearly visible. The process of crushing the root tip and pressing it on a glass object (squash method) was used to expand the observation area. A light microscope with a magnification of 400x and 1000x was used to identify the division phases. Observation results show the presence of all phases of mitosis, namely prophase (nucleolus and nuclear membrane begin to disappear,chromosomes condense), metaphase (chromosomes line up at the equator), anaphase (chromatids separate to opposite poles), and telophase (nuclear membrane and two daughter cell nuclei re-form). Visual documentation in the form of microscopic photographs and descriptive tables clarify the identification of these phases, thus facilitating student understanding.From a pedagogical perspective, this microscopic practicum-based learning has been proven to improve students' observational skills, laboratory skills, and conceptual understanding of cell division. Students not only memorize theories, but directly experience the scientific process through exploration and discussion of observation results. Evaluation of learning outcomes is carried out through post-practicum quizzes and student worksheets, showing an increase in understanding scores of more than 30%.

Critical thinking skills are a fundamental aspect that needs to be instilled early in the educational process in elementary schools. However, the application of conventional learning media such as textbooks and worksheets tends to be less supportive of the development of these skills, especially in complex materials such as the solar system. To overcome this, the use of solar system diorama media is considered capable of bridging students' conceptual understanding with more contextual visual and exploratory experiences. Through a constructivist approach, students are given space to be actively involved in observing, discussing, and linking materials to real phenomena, so that their critical thinking skills can be honed more optimally. This study aims to evaluate the effectiveness of the use of diorama media in improving the critical thinking skills of elementary school students and examine students' responses to this learning method. The results of this study are expected to contribute to the development of innovative learning strategies that can support the quality of elementary education.

Reading comprehension is a crucial skill in learning English, particularly at the Islamic high school level. Students at this stage are often exposed to lengthy texts, yet they still encounter difficulties in fully understanding the content. This challenge may stem from limited use of interactive learning media and the predominant reliance on traditional media, such as monotonous paper-based worksheets that are less engaging. Therefore, this study aims to evaluate the effectiveness of paper worksheets versus Liveworksheet in enhancing reading comprehension among Islamic senior high school students. The research employed a quasi-experimental design with two classes: an experimental group and a control group. Data collection involved pre-tests and post-tests using Islamic-themed reading materials. Data analysis was performed using SPSS software version 25 for Windows, employing paired sample t-tests and effect size calculations to assess the impact of the treatments. Results indicated that the mean post-test score for the experimental group (92.47) exceeded that of the control group (73.63), with the difference being statistically significant (p < 0.05). This suggests that Liveworksheet is more effective than traditional paper worksheets in improving reading comprehension. The effect size, measured using Eta Squared (η² = 0.869), showed a substantial medium effect of using Liveworksheet on students' reading skills. These findings demonstrate that Liveworksheet can effectively enhance reading comprehension and serve as a valuable alternative media for reading instruction.
