Improving Problem Solving Ability through A Scientific Approach on Grade VII MTs Students

Problem-solving skills are highly important in various aspects of life and professions, particularly in mathematics education. However, many students struggle to develop these skills due to a lack of understanding, critical thinking abilities, practice, and motivation. To address this, educators need to adopt teaching strategies that strengthen students' problem-solving skills. One effective approach is the scientific learning model, which emphasizes the scientific process, critical thinking, collaboration, and real-world applications. This study aims to assess the improvement of seventh-grade students' mathematical problem-solving skills using the scientific learning model. The research utilizes a descriptive quantitative approach with a two-group pretest-posttest design. The sample consists of seventh-grade students from an Islamic Junior High School, and data collection includes pretest and posttest questions. The N-gain formula is used to measure improvement. The findings indicate a significant improvement in problem-solving abilities among students who receive instruction using the scientific learning model compared to those who do not. The improvement is categorized as moderate in the experimental class, while the control class shows a lower level of improvement. Factors such as students' enthusiasm, implementation of real-life problems, and increased independence contribute to the improvement in students' problem-solving abilities. The implementation of the scientific learning model significantly enhances students' mathematical problem-solving skills. Based on the field findings, there is a need for improvement in soft skills to support meaningful learning activities.

The Differences of Male and Female Students’s Problem Solving Ability in Environmental Change Topic Based on Education for Sustainable Development (ESD)

This study aims to determine the differences between male and female students’s problem solving abilities in environmental change topic based on ESD. This study used pre-experimental method with one group pretest – post test design. This study located at MA Darul Muqorrobin with subjects 30 students of class X who selected using a purposive sampling technique. Generally, female students’s problem solving ability is higher than male student’s, with a final value of 77.7 for male students and 82.3 for female students. Male students have an average total score higher than female students on the problem understanding indicator, namely 7.7 for male students and 7.4 for female students. In the problem-solving design indicator, female students have a higher average total score than male students, namely 6.1 for male students and 6.5 for female students. Female students have an average total score higher than male students on the indicator of carrying out problem solving, namely 5.8 for male students and 6.4 for female students. In the indicators evaluating problem solving, female students have an average total score higher than male students, namely 5.3 for male students and 5.9 for female students. The high female students’s problem solving ability due to the structure of woman’s corpus collasum which thicker than the men’s. Testosterone hormone causes men prefer learning that hands-on. The preoptic region in the men’s hypothalamus is larger than women’s so men can understand problem better than women. The interpretation of the N-Gain value is sufficient, so the learning of environmental change topic based on ESD is effective to improve problem solving ability in both students.

Use of FOSS for Teaching the Parser Types to Improve Problem Solving Ability A Case Study on Analysis of Gender based Discrimination in Education

Compiler Design is one of the core courses of Computer Science and Engineering. Syntax Analyzer or Parser is important phase in designing the compiler. So while designing this phase of the compiler, students must have thorough knowledge about the types of parser such as LL(1), SLR, Canonical LR and LALR. In the parser phase, the parsing table is built for given Context Free Grammar (CFG). While implementing this parsing phase in laboratory session, two Free Open Source Software (FOSS) - JFLAP and Parsing Emulator, are considered to explain the types of parser and building the parsing table for the CFG using these parser types. JFLAP is software for experimenting with formal languages topics including nondeterministic finite automata, nondeterministic pushdown automata, multi-tape Turing machines, several types of grammars, parsing, and Lsystems. So this tool is considered for parsing phase of Compiler. JFLAP tool is used to explain the steps to be followed to solve the given problem using the parsing technique. Parsing simulator is a software which implements the parsing table for the Context Free Grammars in tool. This simulator is used to generate parsing table (LL1, SLR, LR, and LALR). Parsing Emulator tool is used for practicing the problem statement given in the tool. In current study, use of FOSS such as JFLAP and Parsing Emulator is considered for teaching parser types to improve problem solving ability. The Learning Objectives (LOs) of this study are: To build the parsing table for given CFG using LL(1) and SLR parser (LO1) and to parse the given string using LL(1) and SLR parser (LO2). The research questions for this study are – whether the use of FOSS improves the problem solving ability of the students? and whether gender bias is there in education? Two groups post-test method is considered to check the effectiveness of this use of FOSS in learning the parser types. Also the students’ perception about this method is also considered. The result shows that the students’ problem solving ability of experimental group is improved as compared to the control group irrespective of gender. Keywords- FOSS (Free Open Source Software) JFLAP, Parsing Emulator, Bloom’s Taxonomy, Post-test, t-Test.

A randomized controlled trial of a peer-facilitated self-management program for people with recent-onset psychosis

Early patient-centered interventions can improve mental health and prevent psychotic relapse in people with recent-onset psychosis (ROP). However, limited effective peer-facilitated early interventions are found worldwide. We aimed to test the effects of a four-month peer-facilitated self-management intervention (PFSMI) for Chinese patients with ROP compared with a psychoeducation group (PEG) and treatment-as-usual (TAU) group. A randomized controlled trial was conducted at six Integrated Community Centers for Mental Wellness in Hong Kong. The primary outcome was level of recovery. Secondary outcomes were improvement of problem-solving ability, insight into illness/treatment, and functioning, and reducing psychotic symptoms and re-hospitalization rates. Overall, 180 ROP patients were randomly selected, and after collecting baseline data, randomly assigned to the PFSMI, PEG or TAU (60 per group). Their outcomes were measured at 1-week and 6-month post-intervention. One hundred and sixty-one patients (89.4 %) completed their interventions, with an overall attrition rate of 7.8 % (n = 14). Based on intention-to-treat principle, results of generalized estimating equation test indicated that the PFSMI group reported significantly greater improvements in levels of recovery, functioning and insight into illness/treatment and reductions in psychotic symptoms and duration of re-hospitalizations (p = 0.0007–0.02, with moderate to large effect sizes) than the TAU group at 1-week post-intervention, and both the TAU and PEG at 6-month post-intervention. Significantly fewer PFSMI participants were hospitalized than the TAU and PEG over 6-month follow-up (p = 0.003). The findings support that PFSMI can produce medium-term positive effects on the mental health and functioning of patients with ROP.

The research data was obtained from the results of a limited trial in the tenth grade MIPA 4 SMAN 1 Mataram with a total of 33 people. The data obtained from the next study were tested for the value of n-gain to find out the improvement in problem solving abilities. The results showed that the overall value of n-gain was 0.66 in the medium category. In addition, the n-gain analysis of each problem solving indicator shows that the indicators of recognizing problems and planning strategies have increased with the n-gain value being in the medium category, while the indicator implementing strategies and evaluating solutions has increased with the n-gain value being in the high category. These results indicate that the physics learning tools using blended learning model with video assistance on momentum and impulse materials is effective to improve problem solving ability of students.
