Abstract

Purpose: This study examines students’ ability to comprehend statistical concepts explained by ChatGPT and explores both students’ and lecturers’ perceptions regarding the clarity and instructional appropriateness of ChatGPT’s explanations within the framework of Intelligent Tutoring Systems (ITS), particularly in learning contexts that require high cognitive engagement. Method: A qualitative approach with a quasi-experimental design was employed. Participants were divided into an experimental group that utilized ChatGPT during learning activities and a control group that received conventional lecturer-led instruction. Data were gathered through quizzes, classroom observations, and Focus Group Discussions (FGDs) involving students and lecturers. The collected data were analyzed descriptively using the Miles and Huberman model to identify recurring themes related to conceptual understanding, learning behavior, and instructional effectiveness. Findings: The results reveal that most students experienced substantial difficulty in understanding statistical explanations generated by ChatGPT. Students frequently relied on copying answers without critically engaging with the reasoning process. Major obstacles included fragmented explanations, unfamiliar symbolic representations, and the use of technical language that exceeded students’ conceptual readiness, leading to weak conceptual understanding. Conversely, students who possessed a solid foundation in statistical concepts demonstrated better learning outcomes, even when using ChatGPT. Lecturers consistently emphasized that ChatGPT cannot substitute the pedagogical role of lecturers but may provide limited support when its use is guided and supervised. Significance: This study underscores that ChatGPT should be positioned as a supplementary instructional tool rather than a primary source of explanation in statistics education. Effective integration requires structured guidance, conceptual reinforcement, and the cultivation of students’ critical thinking skills to avoid misconceptions. These findings contribute to the discourse on responsible human AI collaboration in higher education and offer practical implications for implementing generative AI within ITS based learning environments.

Abstract

This study aims to analyze the human resource development (HRD) strategies implemented at the Gunung Terang Village Office, Bandar Lampung City, and to assess their contribution to improving employee professionalism and the quality of public services. A qualitative descriptive method was employed, with data collected through observation, in-depth interviews, and documentation involving all village office employees. The findings reveal that HRD practices at the village office are limited to short-term technical training without support for structured formal education or a competency-based career development system. Although the training provided is relevant to employees’ tasks, it is conducted incidentally and lacks long-term planning, while job promotions are predominantly based on seniority due to the absence of a merit-based system. These conditions create a gap between HRD needs and the strategies currently implemented, resulting in limited strategic impact on bureaucratic quality improvement. This study recommends the formulation of a structured, sustainable HRD strategy grounded in needs analysis to ensure equal access to competency enhancement and to strengthen professionalism among village office personnel.

Abstract

This study aims to develop an ethnomathematics-based pop-up book as a learning medium, integrating geometric concepts within the context of traditional Lampung houses, to enhance students' conceptual understanding of mathematics and to evaluate the responses of teachers and students as well as the effectiveness of the media. The research employed the Borg & Gall development model with seven steps: data collection, planning, initial draft development, preliminary testing, product revision, main field testing, and dissemination and implementation. Data were analyzed using qualitative and quantitative descriptive methods. Validation results indicated that the media fell into the "highly feasible" category, with a score of 90% from material and media experts. Small-scale testing received a "very interesting" response of 92%, while large-scale testing achieved a 94% positive response from 29 students. Improvement in conceptual understanding was evidenced by an N-Gain score of 0.89 (high category), and the media’s effectiveness was shown by an effect size of 1.06 (effective category). The findings imply that the ethnomathematics-based pop-up book is effective in supporting culturally responsive mathematics learning and can serve as an innovative and contextual alternative learning medium.
