Abstract:
Purpose. The purpose of this study is the development of portfolio assessment handbook to promote
the standard of mathematics learning results in Indonesia.Design / methodology / approachThe current
study adopted a mixed methods approach in which both quantitative method and qualitative
method is considered. For qualitative purpose, data collection is carried out by using interviews and
survey is carried out to collect quantitative data. The current study is carried among the elementary
schools of South Kalimantan, Indonesia. Additionally, purposive random sampling is employed
to collect the data from primary school teachers. FindingsThe results of the study demonstrated that the
internal expert and practitioner as part of the evaluation and enhancement of the test cycle is most
significant for developing the learning assessment tool. Furthermore, portfolio evaluation is a novel
learning tool developed for primary mathematics learning activity which is most significant to use
based on the results of internal and external tests. Practical implicationsFindings of the study offer
important insights for educationalists, practitioners, and administrative authorities to design special
lesson plans and evaluation methods for educational institutions. The results of the study are valuable
for practitioners to improve learning and gauge the capacities of students.Originality/valueThis study has
significant contribution to the body of knowledge. Especially, the development of portfolio assessment
handbook has valuable addition to the literature. In rare case, any study developed the portfolio
assessment handbook
