Abstract

The purpose of this study was to determine whether there was any influence of the Logan Avenue Problem Solving Heuristic Model on the Mathematical Reasoning Ability of Class VIII Students of Haruru Christian Middle School, Amahai District, Central Maluku Regency.The method used in this study is a quasi-experimental method that is tested quantitatively. The population of this study was Class VIII class of Haruru Christian Middle School, Amahai District, Central Maluku Regency. The sampling technique used the Non-equivalent posttest only control group design technique. Class VIII1 students as the experimental class were given the Logan Avenue Problem Solving Heuristic model treatment and students in class VIII2 as the control class were given the Direct Learning model treatment. The calculation results obtained the average score of students from the experimental class = 82.82, while the average score of students from the control class = 58.6. Based on the normality test and homogeneity test of the two groups, it was found that the sample data were normally distributed and homogeneous so that the t test was used to test the hypothesis. The calculation results show t count =8.6975> t_table = 2.02108 at a significance level of α = 0.05. Thus H0“is rejected” and “H1 is accepted”. It means “There is an Influence of the Heuristic Logan Avenue Problem Solving Model on the Mathematical Reasoning Ability of Class VIII Students of Haruru Christian Middle School, Amahai District, Central Maluku Regency.

Abstract

The implementation of Natural and Social Sciences (IPAS) under the Kurikulum Merdeka requires learning experiences that connect scientific concepts with students’ real-world environments. This study examined changes in students’ science process skills and environmental awareness through a digital science magazine contextualized to the local potential of Kebon Rojo, Blitar. A pre-experimental one-group pretest-posttest design involved 59 fifth-grade students at SDN Nglegok 01, Blitar Regency. Data were collected using a science process skills test and a five-point Likert-scale environmental awareness questionnaire. Data were analyzed using descriptive statistics, the Shapiro–Wilk normality test, Wilcoxon Signed-Rank test, effect size, and normalized gain. Science process skills increased from M = 3.93 (SD = 2.27) to M = 9.80 (SD = 4.56), with a significant difference (Z = -6.69, p < .001), large effect size (r = .87), and moderate N-Gain (0.58). All six indicators improved, with the largest gains in communicating results (59.2 points) and analyzing data and information (57.2 points). Environmental awareness increased from M = 39.56 (SD = 12.39) to M = 45.90 (SD = 9.76), also showing a significant difference (Z = -4.52, p < .001) and large effect size (r = .62). Environmental responsibility showed the largest increase among the five dimensions (15 points). These findings indicate that contextualizing IPAS learning through Kebon Rojo and interactive digital resources can support improvements in students’ science process skills and environmental awareness.
