Abstract

This study aims to determine the effectiveness of story card media in improving students’ self-confidence in speaking skills at the elementary school level. This research employed a pre-experimental design with a one group pretest-posttest approach. The subjects were 32 fourth-grade students of MIS Hidayatul Hasaniyyah in the even semester of the 2026 academic year. Data were collected using observation sheets of students’ self-confidence during speaking activities. The results showed that the average score of students’ self-confidence before treatment (pretest) was 45.62 and increased to 82.78 after the implementation of story card media. The improvement of 37.16 points indicates that story card media is effective in enhancing students’ self-confidence in speaking. Therefore, story card media can be used as an alternative learning medium to encourage students to express their ideas more confidently.

Abstract

This study aims to determine how the Jigsaw learning model assisted by digital media tables of snakes and ladders affects students' learning interest in mathematics learning in grade III at SDN Kota Bengkulu. This study is a quantitative study using a quasi-experimental method. The type of research design applied is a Control Group Pretest-Posttest Matching Only design. This study involved grade III students of SDN 38 Kota Bengkulu. Meanwhile, the sample consisted of grade IIIB students of SDN 38 Kota Bengkulu, which served as the experimental class, and grade IIIA students of SDN 38 Kota Bengkulu, which served as the control class. This sample was taken through a random sampling group. Non-test tools were used in measuring learning interest using initial and final questionnaires. The results of the hypothesis test in the experimental class show that the t-value with the assumption of the same difference = 4.675, the two-tailed sigma value is 0.027, and the distribution value is 1.967, so that the t-value is greater than the t-table (4.308 is greater than 1.697), and the two-tailed sigma is 0.037 less than 0.05. These data show that the difference in average learning interest between the experimental class and the control class is caused by the way each class is treated. Thus, it can be concluded that the Jigsaw learning model assisted by digital media snakes and ladders has an impact on students' learning interest in mathematics subjects in grade III at SDN 38 Bengkulu City.

Abstract

This study aims to determine the effect of the Project Based Learning (PjBL) model on the mathematical conceptual understanding of fourth-grade students in Cluster XIV, Bengkulu City. The research is quantitative, using a quasi-experimental method with a Matching Only Pretest-Posttest Control Group Design. The population consisted of fourth-grade students in Cluster XIV. The sample included class IVA of SDN 42 Bengkulu City as the experimental group and class IV of SDN 45 Bengkulu City as the control group, selected using Cluster Random Sampling. The instrument used was an essay-format test to assess students’ mathematical conceptual understanding through pretests and posttests. Data were analyzed quantitatively using descriptive statistics, prerequisite tests, and inferential analysis through a t-test. The results showed a significant difference between the posttest average scores of the experimental class (77.90) and the control class (57.86), with the experimental group scoring higher. Based on the t-distribution table with df = 41 and a significance level of 5%, the critical value was 1.683. The analysis showed that t_calculated > t_table (5.786 > 1.683) and the significance value (2-tailed) = 0.000 < 0.005. Therefore, H₀ is rejected and Hₐ is accepted. It can be concluded that the Project-Based Learning model significantly affects the mathematical conceptual understanding of fourth-grade students in Cluster XIV, Bengkulu City.

Abstract

This research aims to develop a learning media in the form of the ICARUS (Interactive Creative Active Relevant Understanding Shape) application for plane geometry material as an effort to support mathematics learning for fourth-grade students at State Elementary School 81 Bengkulu City. This research is a Research and Development (R&D) study using the ADDIE development model. The research was conducted in 5 stages: analysis, design, development, implementation, and evaluation, carried out through small-scale trials to measure teacher and student responses. The instruments used were product validation sheets, teacher response questionnaires, and student response questionnaires. The feasibility of the ICARUS application was obtained through validation results conducted by four competent expert validators, including material experts, language experts, and graphic design experts. The validity of the ICARUS application learning media was obtained based on Aiken's V calculation results with an average material validity value of 0.96, language 0.86, and graphic design 0.93, all of which fall into the "very valid" category. Reliability testing using Percentage Agreement (PA) showed an agreement percentage above 80% with a strong agreement level, proving the consistency of assessments among validators and the reliability of the validation instrument. The practicality percentage value of the ICARUS application through teacher responses was 97.3% and student response results were 92.96% with an overall average of 95.13%, falling into the "very practical" category. The validation and small-scale trials through teacher and student responses indicate that the ICARUS application is highly valid and suitable for use as a mathematics learning media for plane geometry material in elementary schools.

Abstract

This study evaluates the theoretical and empirical feasibility of a science literacy assessment instrument integrated with Bengkulu’s local wisdom, Rimbo Larangan, for elementary students. Using the R&D approach with the ADDIE model, the instrument was designed to align scientific literacy dimensions (context, competence, knowledge, and attitude) with local ecological values. Data were collected via expert validation and trials with 30 students, then analyzed using Aiken’s V and descriptive statistics. Results show high theoretical feasibility with an Aiken’s V index of 0.88 and inter-rater reliability of 0.87. Empirically, the instrument demonstrated high reliability (Cronbach’s Alpha 0.89) and valid item distribution across varying difficulty levels. Analysis of student profiles revealed that while the local context significantly boosted scientific attitudes (78%), scientific competence (58%) remains a challenge, particularly in evidence-based reasoning. This study concludes that the Rimbo Larangan-based instrument is a feasible and valid tool for measuring science literacy contextually. It bridges the gap between school science and indigenous ecological knowledge, fostering both environmental awareness and critical thinking in elementary education.
