Objective: The assessment approach is crucial to achieving learning outcomes. Contonuous-Assessment (CA) is one alternative assessment that can be used to increase various skills. This preliminary study aims to: (1) formulate CA and project-based assessment in higher education; (2) describe the lecturer's and students' perception of CA in the postgraduate program; (3) map course assignments within the framework of CA at the postgraduate level. Method: Data was collected through Forum Group Discussions (FGDs) and questionnaires. Data were analyzed both qualitatively and quantitatively. Results: The results show that the conceptual study of the CA should pay attention to the purposes, improve the learning process, involve students fully and purposefully in their learning, and explore the factors that influence the learning process. The design of CA is realized as demand mapping for each course in the form of products or small projects as part of the stages for completing a thesis/dissertation. Most lecturers and students agree that the lecture process uses a CA design in which each course contributes to achieving the thesis/dissertation. A small number of them disagree and give some suggestions. Novelty: The novelty of this research is to produce a mapping of assignments from all courses, which leads to the completion of writing a thesis/dissertation.

The aim of this research was to produce a web based instrument test to assess higher order thinking skills that are feasible and to describe the profile of students higher order thinking skills. This research using Research and Development (R&D) model from Borg and Gall with ADDIE (Analysis, Design, Development, Implementation, and Evaluation ). Data collection techniques in this study are the validation method that done by three lecturers from the physic department of State University of Surabaya and test method that done by 29 students of class X MIPA-2 SMA At-Ta’miriyyah using Quizizz. The data that has been collected were analyzed using quantitative decriptive analysis method. The percentage of average theoritical validity in the realms of construction, language, and media is is 97.03% or in the very feasible category. The result of product trials on 29 students analyzed the level of distinguishing power, reliability, and item validity. From the analysis obtained empirical validity as many as 10 questions declared empirically feasible. The appropriate test instrument is then used to describe the profile of students higher order thinking skills abilities. A viable test instrument is then used to describe the student's high-level thinking ability profile. 44.83% of students in very high categories, 13.79% with good categories, 0% with sufficient categories, and 41.38% with less categories. The ability to think high level in the competency of analyzing (C4) is lower at 67.49% compared to the evaluating competency (C5) of 80.46%.

This study aims to examine the concept of the nature of science (NOS) and attitudes towards teaching the NOS. The research used the View on Science Education (VOSE) instrument that was developed by Chen (valid and reliable) which online distributed to students of Physics Education Program from Surabaya State University and IKIP PGRI Pontianak, as well as students of Science Program from IAIN Ponorogo. The survey research method was conducted to determine the profile of students’ views on the NOS and science education. Respondents who filled out the research questionnaire were 102 students. Based on the survey results, the VOSE profile was obtained that the Science-Physics students had difficulty conceptualizing the general picture of VOSE because in some aspects of NOS it appeared that students experienced confusion.Science-Physics students have a positive attitude towards teaching NOS in terms of tentativeness, aspect of the nature of observation, as well as aspect of theory and law.However, Science-Physics students have negative attitudes towards teaching NOS in the aspect of the scientific method. Thus, the implication of this research requires that Science-Physics students learn and further research about the concept of NOS in order to have a correct understanding.

Guided Inquiry is one of the learning models that often used in research into the application of learning models in physics learning. This study aims to analyse the learning process with the Guided Inquiry model and its effect on increasing the students’ competence and skills from previous studies. This research method uses meta-analysis with stages: data collection, data reduction, data display, and drawing conclusions or verification. The secondary data used, that is, data collected indirectly on the object studied in the form of 20 national and international journal articles. The first step in this research is to collects journals, selection 20 journals with the same research design, creates a visualisation in VOSviewer software, and calculates the effect size of the research results. The meta-analysis topic discusses in the research is about to improve students' science skills, school level, subject matter and then the media used. The results of the study state that learning physics using Guided Inquiry model can improve the scientific literacy competencies, critical-thinking skills, and students learning outcomes that measured separately (moderate effect) and simultaneously (modest effect). Another results show that Guided Inquiry model recommended for students that have higher-order-thinking skills, apply with real learning-media, and used for the investigated characteristic content-material. Keywords: Guided Inquiry, physics learning, meta-analysis

This paper aims to analyse the research trend of erbium-doped tellurite glasses. To this aim, this paper applied bibliometric analysis. The comprehensive research document on the topic of erbium-doped tellurite glasses in the Scopus database is 695 documents. The result revealed that scientific publication on erbium-doped tellurite glasses has been increasing. China contributed the most documents on erbium-doped tellurite glasses. The visualization of the research trend on erbium-doped tellurite glasses assisted with VOSviewer software and resulted in four primary clusters: (1) the red cluster show the keywords about the synthesized and fabrication, (2) the blue cluster show the keywords about the characterization, (3) the green cluster show the user or the application of the glass with each characteristic of materials, (4) the yellow cluster show the way to analyse energy based on the parameters owned by erbium-doped tellurite glasses. The research findings are the networking of the keywords on the research of erbium doped tellurite glasses in all clusters. It means that this research is comprehend knowledge and need to be more investigate to further research.

The aim of this paper is to review the optical properties of tellurite glasses doped by erbium and describe their bibliometric study about it. The research documents on of optical properties of tellurite glasses doped by erbium in the Scopus database are 115, start from 1999 until now. The visualization of the research assisted by VOSviewer software. There are three clusters: (1) red cluster for the optical properties begin from the fabrication process until the characterization of glasses based on the geometrical optics phenomena, (2) green cluster for the emission spectra until the analysis using McCumbers Theory, and (3) erbium-doped tellurite glasses optical properties based on energy transfer and XRD analysis on the blue cluster. Based on the Scopus documents, not too many researchers are concerned with researching erbium-doped tellurite glasses, never more than 12 documents per year. However, the researchers are consistent to explore further exploring the characteristics of the optical properties of glass exposed to erbium ion for laser applications.The research funding shows that the tellurite glasses doped by erbium are being developed for laser applications.
