Research use a qualitative approach with subjects of this study were students from Mathematics Education Study Program of universities in Semarang who were carrying out teaching practice programs in schools. It can be concluded from the results of the above research analysis that the readiness of prospective mathematics teachers to use technology in 21st century learning is included in good criteria. The readiness is seen from: the knowledge that has been obtained during learning process in college; the facilities and infrastructure at college are adequate for students to access technological developments; the planning in creating the lesson tailored to the material, objectives and characteristics of students in the class; there is support from schools; mathematics teacher candidates also have good perceptions related to the integrated technology in mathematics learning.

Learning and learning must focus on the use of emerging or existing technological innovations [1]. In teaching and learning process, there are three subjects that cannot be overlooked, namely: educators, learners and materials. Educators here can be teachers or lecturers. The scary challenge facing the education system is the lack of competent teachers that are proficient in literacy or information technology [2]. Information communication technology (ICT) expertise is the ability to use technological tools and networks to determine, access, manage, integrate and evaluate the information from various sources; this ability is known as Information literacy [3]. Information and communication technology in learning act as a liaison in the implementation of knowledge transfer without completely eliminating the initial model of learning that takes place face-to-face in the classroom [4]. Utilization of technology in the learning process is of course intended for all fields of science, including mathematics. Mathematics which is more abstract is easier to learn if the abstract object is changed in a concrete form. Therefore, the need for tools in the use of technology in mathematics learning can be in the form of instructional media. One form of utilizing the technological ICE 2019, September 28-30, Purwokerto, Indonesia Copyright © 2020 EAI DOI 10.4108/eai.28-9-2019.2291090
