Implications of Problem Based Learning Model on Students' Critical Thinking Ability in Arithmetic Sequence
No full textEffective education requires an approach that encourages ability to analyze critically, particularly when learning mathematics which is often considered challenging by students. Problem Based Learning model is considered capable of developing students' critical thinking abilities through real problem solving and collaboration. The purpose of this study is to find out how the Problem Based Learning approach affected the critical thinking abilities of Grade X students at SMAN 1 Driyorejo in the subject of arithmetic sequences throughout the 2024–2025 school year. The research employs an appropriate experimental design, namely the pretest-posttest control group design, and takes a quantitative approach.. The sample includes two classes: class X-6 as the experimental group implementing the Problem Based Leaning model, and class X-7 as the control group applying conventional teaching methods. Critical thinking assessments were used to gather data both before and after the intervention. To ascertain whether there was a significant difference between the two groups, the data were examined using a t-test. The findings indicated that the average pretest scores for the control and experimental classes were 31,91 and 58,71, respectively, while the average posttest scores were 46,48 and 90,05. Before testing the hypothesis, students' critical thinking test scores must be checked for normality and homogeneity to ensure the data is normally distributed and has the same variance. The data analysis's findings demonstrate the worth of t_count>t_table, result is |-19,826>-1,995 | for pretest questions and the value of t_count>t_table, result is |-48,278>-1,995| for posttest questions. Thus, when compared to conventional teaching approaches, the data analysis results demonstrate that the Problem Based Learning model significantly improves students' critical thinking abilities.Keyword: Problem Based Learning, Critical Thinking Abilities, Arithmetic Sequenc
Impact of Discovery Learning Model on Students' Critical Thinking Skills in Mathematics Learning
No full textCritical thinking abilities and mathematical content are closely related since students must use critical reasoning, analysis, and problem-solving techniques to grasp mathematical ideas. However, field data reveals that many students still experience difficulties in developing adequate mathematical critical thinking abilities. This study aims to investigate the influence of implementing the Discovery Learning model on students’ mathematical critical thinking skills. The research employed a quantitative approach with a quasi-experimental design. The population included all grade X students at SMAN 1 Driyorejo in the academic year 2024/2025. Through purposive sampling, two classes were selected as research samples: class X-1 as the control group taught using conventional learning methods such as lectures and repetitive practice, and class X-5 as the experimental group that received instruction through the Discovery Learning model. Data were collected through a posttest administered after the learning intervention. The instrument consisted of five story-based questions centered on arithmetic sequences, designed to assess students’ critical thinking in mathematics. The data analysis process began with the normality test using the Chi-Square method, followed by a homogeneity test using the F-test to validate statistical assumptions. Upon meeting these requirements, the t-test was conducted to examine the research hypothesis and compare the posttest results of both groups. The findings revealed that the Discovery Learning model had a significant positive impact on students’ mathematical critical thinking skills. Therefore, it is recommended that this model be utilized more broadly across various subject matters and educational levels to foster deeper engagement and critical thinking among students
Exploring the Relationship Between Lateral Thinking and Creativity
No full textThis study aims to analyze the relationship between lateral thinking ability and creativity among high school students. A total of 158 students were assessed using lateral thinking and creative thinking tests to evaluate their skills. The results revealed a significant positive correlation between these two abilities, indicating that students with higher lateral thinking scores tend to have better creative thinking scores. Linear regression analysis showed that lateral thinking skills could be a significant predictor of student creativity. However, despite the regression model indicating a strong relationship, some data variation suggests that other factors, such as motivation or learning environment, may also influence creativity. This study highlights the importance of lateral thinking skills in fostering creativity and provides recommendations for further research to consider additional variables and employ more complex modeling approache
