Abstract

Perkembangan teknologi digital telah mendorong munculnya berbagai aplikasi edukatif untuk anak usia dini (2 hingga 6 tahun). Namun, hingga saat ini sebagian besar aplikasi tersebut belum dirancang secara optimal sesuai dengan prinsip perkembangan anak, terutama dalam hal seperti beban kognitif, interaktivitas, dan sosial kontekstual. Penelitian ini bertujuan untuk mengidentifikasi dan mengelompokkan indikator krusial yang seharusnya dimiliki oleh aplikasi pendidikan anak usia dini, guna mendukung proses pembelajaran yang efektif, menyenangkan dan sesuai dengan tahap perkembangan mereka. Metode yang digunakan yaitu menggabungkan literatur review, aplikasi aktual dan kuesioner berbasis expert judgement, dengan melibatkan tiga kelompok yaitu pengembang aplikasi pendidikan, guru taman kanak-kanak, dan orang tua murid. Sebanyak 55 indikator dievaluasi, dikaji serta dianalisis menggunakan pendekatan Relative Importance Index (RII). Hasilnya menunjukkan bahwa terdapat 28 indikator dinilai penting oleh para ahli, yang kemudian hasil tersebut diklasifikasikan ke dalam tiga dimensi utama yaitu (1) faktor kognitif dan pembelajaran, (2) faktor interaktivitas dan teknologi, serta (3) faktor sosial dan kontekstual. Temuan ini menghasilkan sebuah kerangka evaluasi multidimensi yang dapat dijadikan sebagai acuan dalam perancangan dan penilaian aplikasi pendidikan anak usia dini yang lebih efektif dan sesuai dengan tahapan perkembangan anak usia dini.  Abstract[Development of an Evaluation Framework for Early Childhood Educational Application: Integrating Cognitive, Interactivity and Social Contextual Aspect] The advancement of digital technology has led to the emergence of various educational applications for early childhood (age 2 to 6). However, most of these applications have not been optimally designed in accordance with child development principles, particularly regarding cognitive load, interactivity, and socio contextual aspects. This study aims to identify and categorize the key indicators that should be incorporated into early childhood educational applications to support effective, enjoyable, and developmentally appropriate learning experiences. The method combines a literature review, analysis of existing applications, and an expert judgement based questionnaire involving three groups such as educational application  developers, kindergarten teachers, and parents. A total of 55 indicators were evaluated and analyzed using the Relative Importance Index (RII) approach. The findings reveal that 30 indicators were rated as important by the experts, which were then classified into three main dimensions such as (1) cognitive and learning factors, (2) interactivity and technology factors, and (3) social and contextual factors. These results form a multidimensional evaluation framework that can serve as a reference for designing and assessing early childhood educational applications that are more effective and aligned with children’s developmental stages.Keywords: cognitive load; early childhood educational application; interactivity; multidimensional evaluation; social context

Abstract

Recent empirical research on mathematical creativity using eye-tracking (ET) technology has faced challenges in developing comprehensive overviews due to the diversity of tools, task types, ET metrics, and identification methods. Thus, this systematic review attempts to examine studies that focus on mathematical creativity and incorporate ET technology. Guided by Newman and Gough’s seven-step approach, a Scopus database search covering publications up to 2024 identified five eligible empirical studies collected for this study. The review reveals that researchers employed two primary types of eye trackers: screen-based trackers, which are affordable and unobtrusive, and eye-tracking glasses, which enable participants to engage in paper-and-pencil tasks while moving naturally. To stimulate creative thinking, the studies utilized open-ended mathematical tasks—particularly geometry-based multiple solution tasks (MST) and visual modeling tasks—that encourage divergent exploration. In analyzing creative processes, researchers combined ET metrics such as fixation duration, fixation count, and scan paths with gaze-overlaid videos, offering complementary insights into visual attention patterns and idea development. Additionally, several studies integrated ET with stimulated recall interviews (SRI), allowing participants to reflect on their strategies and deepening the interpretation of cognitive processes. This methodological combination effectively captures both visual behaviors and participants’ reflections, highlighting the complexity of creative thinking in mathematics and offering guidance for future research and instructional practice.
