SYSTEMATIC LITERATURE REVIEW: THE EFFECT OF PROBLEM-BASED LEARNING MODELS ON STUDENTS' MATHEMATICAL PROBLEM-SOLVING SKILLS AND EMOTIONAL INTELLIGENCE
In modern education, two elements are considered crucial: mathematical problem-solving ability and students' emotional intelligence. Both are seen as vital assets for facing the challenges of the 21st century. The Problem Based Learning (PBL) model is often hypothesized as an approach that can sharpen both of these domains simultaneously. However, this hypothesis needs to be proven by synthesizing existing empirical findings. Therefore, this systematic literature review was conducted to answer the question: to what extent does PBL influence these two abilities? Guided by the Systematic Literature Review (SLR) method and the PRISMA framework, we searched and screened various research articles from scientific databases. We focused on experimental and quasi-experimental studies published in the last decade. After a rigorous selection process, a number of eligible articles were identified and analyzed. Our analysis reveals a consistent finding: the implementation of the PBL model has a proven, positive, and significant impact on students' mathematical problem-solving abilities. In a PBL environment, students do not just memorize formulas; they are actively involved in understanding problems, designing solution strategies, and evaluating outcomes. Furthermore, the collaborative and interactive learning process in PBL also turns out to be fertile ground for nurturing emotional intelligence. Students learn to manage their emotions when facing difficulties, build intrinsic motivation, empathize with teammates, and hone their social skills. From this synthesis, we can conclude that the Problem-Based Learning model is more than just a strategy to improve math scores. It is a holistic approach that successfully bridges the development of critical thinking skills with emotional maturity. This finding underscores the urgency of further integrating PBL into the curriculum, aiming to shape a generation that is not only intelligent but also resilient and collaborative
Basic Anatomical Study of Pollen, Stigma, and Sheath in Bougainvillea Flowers
It is important to study the basic anatomy of pollen, pistils and midribs of bougainvillea flowers to improve the quality of plant reproduction, breeding and improving varieties, as well as optimizing the use of bougainvillea as ornamental plants. Bougainvillea plants have various varieties, there are three varieties sampled in this research, namely pink paper flowers (Bougainvillea bambino baby lauren), orange paper flowers (Bougainvillea afterglow), and purple paper flowers (Bougainvillea barbara karst). This research aims to determine the anatomical structure of pollen, stigma and midrib of bougainvillea plants. This research method uses descriptive methods. The sampling technique used was purposive sampling and sample measurement under a light microscope with 10x magnification. The results of the research show that three varieties of paper flowers, namely Bougainvillea bambino baby lauren, Bougainvillea afterglow, and Bougainvillea barbara karst, all three have pollen that allows the trichoporate type, with finger-shaped, rather slender, and elongated stigmas. then the long petals are orange, pointed or slightly curved, and layered around the original flower. Furthermore, the stigma of each flower has a color that matches the color of the sheath. This research provides a reference for bougainvillea flower variability, reproductive ecology, and genetics in context and conservation
Study on the Development of Indonesia and Malaysia Shallot Imports
This study analyses shallot import trends in Indonesia and Malaysia from 2010 to 2023. Indonesia, while a net exporter, experiences fluctuating imports, primarily due to seasonal production variations and occasional supply shortfalls. Malaysia, lacking significant domestic production, consistently relies heavily on imports, primarily from India. The study utilises a descriptive qualitative method, incorporating both primary (interviews, observations) and secondary data (government reports, trade statistics). Key findings highlight Brebes, Indonesia, as a major shallot production centre, employing technologies like Controlled Atmosphere Storage (CAS) to extend shelf life. Data mining techniques, specifically linear regression, are used to predict shallot yields based on factors like land area, fertiliser use, and labour. Despite improved productivity per hectare, total production in Brebes fluctuated, indicating challenges in maintaining production scale. Malaysia's shallot import dependence is underscored by its reliance on 24 countries, with India being the largest supplier. MARDI's efforts to cultivate local shallot varieties represent a step towards self-sufficiency. The study examines factors driving imports, including resource limitations, consumption needs, competitive advantages, and economic policies. The instability of shallot production, particularly during the rainy season, contributes to price fluctuations. The analysis concludes by emphasising the need for both countries to enhance domestic production through technological advancements, improved cultivation techniques, and supportive government policies to reduce import dependence and stabilise prices
Self-Regulated Online Learning and Students’ Attitude as Predictors of Skill Proficiency Development in Mathematics
This study aimed to determine if self-regulated online learning and student’s attitude were predictors of skill proficiency development in Mathematics. 200 GE 4 students of UM North Campuses were the respondents of this research. The statistical tools used were Mean, Pearson-r, and Regression Analysis. Quantitative non-experimental research utilizing correlational technique with regression analysis was the research design of this paper. Results revealed high self-regulated online learning among GE 4 students in terms of metacognitive skill, time management, environmental structuring, persistence, and help seeking was high. The level of students’ attitude towards learning Mathematics yielded a descriptive equivalent of high confidence in Mathematics, the importance of Mathematics, and engagement in Mathematics. The level of skill proficiency development of the students in Mathematics yielded a high-level result in terms of conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and productive disposition. There was a positive significant relationship between self-regulated online learning and students’ attitude to skill proficiency development in Mathematics.

THE EFFECTIVENESS OF HOTS-ORIENTED LEARNING ON ACHIEVEMENT OF STUDENT HOTS
This research is motivated by the findings regarding the difficulties experienced by students in solving combinatorial problems as an indication of weak High Order Thinking Skills (HOTS) students. The reason is that the lecture process has not facilitated active and interactive student involvement, where the lecture process is dominated by lecturers through the lecture method. Lecturers' formative and summative assessments are mostly because they only access understanding and mastery of the material, are not contextual, and have not facilitated student HOTS achievement. This study aims to improve student HOTS through the application of HOTS-oriented learning. The HOTS-oriented learning components in this study include HOTS-based strategies and models, media, and assessments. The type of research used is a quasi-experimental study with a one-group pretest-posttest design. The sample for this research was 17 students taking discrete mathematics courses for the 2022/2023 Academic Year. The data obtained were analyzed descriptively in the form of mean, standard deviation, and n-gain and inferential analysis using the one-way Multivariate Analysis of Variance (MANOVA) test. The results showed that students' HOTS experienced an increase after applying HOTS-oriented learning in the four aspects of the skills assessed, namely the skills of analyzing, evaluating, and creating; problem-solving skills; creative thinking skills, and critical thinking skills, with an average increase in the medium criteria. Learning that is applied effectively to student HOTS achievement
Promoting self-reflection over re-teaching: Addressing students’ misconceptions with ‘my favorite no’
Misconceptions are an important aspect of learning and teaching mathematics. What are effective ways for teachers to confront misconceptions and prevent their reoccurrence?  This mixed-methods study examined instrumental and conceptual understandings of students’ errors, mistakes, and misconceptions in a 7th grade mathematics classroom utilizing the ‘My Favorite No’ strategy. Fifty-five students from a Midwest middle school were divided into two groups with similar abilities, with one group confronting misconceptions using the ‘My Favorite No†strategy while the other group received information about a potential error directly from a teacher. A brief survey of questions followed for students in the “My Favorite No’ class. One group was concerned with conceptual understanding and making connections, and able to solve similar problems. In the second group, students improved from pretests, yet did not improve as much as students using ‘My Favorite No.’ Thus, teachers are encouraged to consider using “My Favorite No†a strategy where students are in an environment in which they discover their errors and believe in the value of making a mistake.Â
