“…The risk may arise from student misunderstood that will lead misconception for the following content. There are several misconception about electronic configuration in students caused by insufficient knowledge about quantum theory and electronic transitions (Anwar et al, 2012). The discussion of electronic transitions is essential in REE topic because of the relation to the properties of elements such as luminescence.…”

Rare Earth Elements (REE) is an interesting chemistry topic, especially due to current technology development. However, new learning designs of REE need to be developed for Pre-service Chemistry Teachers (PCT) as it is not yet available. A good design is constructed by analyzing PCT pre-conceptions based on the technical difficulties faced by the students during teaching process. The study aims to identify PCT's pre-conceptions focusing on REE topic. We conducted this research involving 17 chemistry education students at the Universitas Pendidikan Indonesia, Bandung. Data was collected through interviews and analyzed using the Qualitative Content Analysis (QCA) method. Our results highlight that PCT had difficulties with chemistry content of REE, especially about electronic configuration, magnetic, and luminescence properties. In addition, PCT faced difficulties correlating electronic configuration's chemistry content into contexts. Based on the interview results, 88.2% of the students agree with the development learning design for undergraduate chemistry students. As a result, we conclude that technical difficulties and misconceptions about REE can be overcome by developing the learning design based on the need of the students.

This study aims to obtain the feasibility of Augmented Reality-based Element Card interactive media on the electron configuration submaterial according to Bohr's theory. This research uses a 4D model which is only carried out until the development stage. This research was conducted at SMAN 1 Gedangan Sidoarjo on 30 students X IPA. This study used a validation sheet instrument, pretest and posttest questions, student response questionnaires, and student observation questionnaires. If the value of the validation result is ≥ 61% then it is considered valid, the practicality value is ≥ 61% then it is considered practical, and the effectiveness value if it is classified above 0.3 which includes medium or high then it is considered effective. The results of content and construct validation are 88% and 84% are included in the very valid category. Practicality was obtained from 94.86% and 97% of student responses and observations included in the very practical. The effectiveness is obtained from learning outcomes by calculating the N-Gain and Wilcoxon Signed Ranks Test, the value of Asymp. Sig (2 tailed) is 0.000 which is smaller than 0.05 so there is a difference in the students' pretest and posttest scores. This proves that the interactive media based on the Augmented Reality Element Card can be used for chemistry learning media.
