Statistics education research integrated with Islamic studies (A study of validity and practicality of textbook development)

Introduction

Statistics education research integrated with islamic studies (a study of validity and practicality of textbook development). Develops a highly valid & practical statistics education research textbook integrated with Islamic studies, fulfilling the need for effective educational resources.

Abstract

This research is based on the need for a textbook of educational research statistics that is suitable for use, while its availability has not been met. Therefore, this research is a development study with ADDIE design (analysis, design, development, implementation, and evaluation), which aims to develop and produce an Islamic integrated educational research statistics textbook that meets valid and practical criteria. The data in this study were collected using questionnaire techniques and validity and practicality questionnaire instruments. Development is first carried out before these two instruments are used to ensure their feasibility. The data that has been obtained is analyzed using the Aiken index formula related to the calculation of validity and percentage related to practicality. The results of this study can be summarized in two conclusions. First, the Islamic integrated educational research statistics textbook is at the "very valid" validity level. The Aiken index score is 0.9215. Second, the Islamic integrated educational research statistics textbook based on mathematical communication skills is at the "practical" level of practicality. The numerical validity value is 77.66%. The implication of the results of this study is the production of a textbook that is suitable for use and tested for its effectiveness in learning educational research statistics.

Review

This study addresses a compelling need for a specialized textbook in educational research statistics, uniquely integrating Islamic studies. The researchers' objective to develop a valid and practical resource for a identified gap in available materials is highly relevant and commendable. The adoption of the ADDIE design framework (Analysis, Design, Development, Implementation, and Evaluation) provides a structured approach to the development process, promising a systematic output. This innovative intersection of statistics education and Islamic studies has the potential to offer a culturally relevant and engaging learning experience, making a distinct contribution to pedagogical resources. The methodology for assessing validity and practicality appears appropriate for a development study. The use of questionnaire techniques, the Aiken index for validity (resulting in a "very valid" score of 0.9215), and percentage calculations for practicality (achieving a "practical" level with 77.66%) provides clear metrics for the textbook's quality. However, some aspects warrant clarification. The abstract mentions that the practicality assessment is based on "mathematical communication skills," yet the abstract does not elaborate on how these skills were integrated into the textbook design or specifically measured within the practicality questionnaire. Furthermore, the term "numerical validity value" attributed to the 77.66% practicality score is confusing and likely a misstatement, as this percentage reflects practicality rather than validity. While the ADDIE model includes "implementation" and "evaluation," the abstract primarily details development-phase assessments of validity and practicality, leaving the extent of actual classroom implementation and a broader evaluation of learning effectiveness somewhat ambiguous. The development of a textbook achieving "very valid" and "practical" status is a significant outcome, offering a much-needed resource for educational contexts aiming to blend these disciplinary perspectives. The stated implication of producing a textbook "suitable for use and tested for its effectiveness in learning" is promising, although the abstract's results mainly detail initial suitability and perceived practicality rather than direct evidence of improved learning outcomes. Future research could greatly benefit from a more explicit articulation of the pedagogical philosophy underpinning the "Islamic integration" and the role of "mathematical communication skills" within the textbook's design. A follow-up study focusing on the long-term impact on student engagement, understanding of statistics, and application of research methods in a practical learning environment would further solidify the value and effectiveness of this developed resource. Overall, this study presents a valuable initial step in creating specialized educational materials, enriching the field of statistics education.
