Abstract

Public speaking is an essential part of communication skills that are not easily mastered by everyone. Anxiety about speaking in public often hinders individuals from developing. The negative impacts can be seen from the physical and emotional health disorders they experience. Lack of confidence when speaking in public is also experienced by students of MAN 2 North Lampung. The right solution is to hold public speaking training that can build students' confidence in speaking in public. The approach is a sequence of training sessions that are precisely and clearly organized within a given time period, tailored to the organizer's time and location available. The activity's outcomes demonstrate that a large number of high school students are interested in public speaking, and we can observe that each student has good potential when it comes to public speaking practice. The inference that may be made is that public speaking abilities are fundamental and should be had by everyone, particularly high school pupils who will find them valuable in the future.

Abstract

Creative thinking ability is one of the essential skills that students must possess and is also a mandatory competence in accordance with educational objectives. The low level of creative thinking ability among Grade X students at MAN 2 Lampung Utara is one of the main concerns of this study. The aim of this research is to determine how students' creative thinking ability is influenced by the open-ended learning paradigm and Adversity Quotient (AQ), and to examine how the interaction between the learning model and AQ affects creative thinking ability. All Grade X students at MAN 2 Lampung Utara were involved as research subjects, with Class X-4 serving as the control group and Class X-5 as the experimental group, selected through cluster random sampling. An essay test consisting of four questions, validated both by experts and empirically, was used to measure creative thinking ability. The Adversity Response Profile (ARP) instrument, consisting of 30 items, was used to assess AQ. Two-way ANOVA was employed to evaluate the data. The conclusions drawn from the analysis are as follows: (1) students' creative thinking ability is significantly influenced by the use of the open-ended learning model; (2) students' creative thinking ability is significantly influenced by AQ; and (3) no interaction was found between the variables.

Abstract

The low mathematical literacy of junior high school students in Indonesia remains a challenge, as reflected in PISA results that consistently place Indonesia at the bottom in mathematical reasoning. This study aims to examine the effectiveness of Problem-Based Learning (PBL) assisted by H5P interactive videos in improving mathematical literacy compared to PBL without digital media. A quasi-experimental method with a Nonequivalent Control Group Design was applied to two grade VIII classes of a state junior high school in Cirebon, each consisting of 36 students. The instrument was a mathematical literacy test based on three PISA indicators: formulating, employing, and interpreting. Data analysis included normality, homogeneity, and an Independent Samples T-Test, supported by N-gain calculation. The results showed no significant difference in pre-test scores between the groups, indicating comparable initial ability. However, the experimental class achieved an N-gain of 0.71 (medium–high category), higher than the control class of 0.38 (low–medium category), with a significance level of 0.000 < 0.05. These findings confirm that integrating H5P into PBL significantly improves students' mathematical literacy. The study concludes that interactive media serve not only as a learning aid but also as a pedagogical tool that fosters participatory, contextual, and meaningful learning, providing practical recommendations for mathematics teachers to adopt innovative digital approaches.
