As a personal research note, this paper presents the summary and review of the course material "Assessment of English Language Learners" from the author's participation in the Massive Open Online Course (MOOC) program offered by the U.S. Department of State as the Online Professional English Network (OPEN). This article is suitable for practical tests for ESL/EFL teachers in classes where students learn English as a second language. It aims to fill the lack of literature on assessing English Language Learners, especially regarding meaningful and purposeful assessment studies in L2 language classes. This paper serves the information as a contribution to 1) determine a meaningful assessment; 2) collect and use data to use the right assessment; 3) select the types of alternative assessment; 4) foster students' motivation and engagement through assessment; and 5) making assessment fun. This paper's contributions will supplement teachers in determining the most appropriate assessment in line with their students' needs. In addition, assessment should act as an evaluation tool and be turned into something fun in the classroom so that students can get many benefits at once, namely learning experiences and learning outcomes. This article is recommended for practical assessments for EFL teachers in English second language learning classes.

Alumina (Al2O3) or Aluminum Oxide is the only oxide formed by the metal aluminum and occurs in nature as the minerals corundum (Al2O3); diaspore (Al2O3·H 2O); gibbsite (Al2O3·3H2O); and most commonly as bauxite, which is an impure form of gibbsite. The precious stones ruby and sapphire are composed of corundum (and thus also natural forms of alumina)-- getting their colors by small amounts of impurities. The importance of alumina is two-fold; it is used as a starting material for the smelting of aluminum metal, and used as a raw material for a broad range of advanced ceramic products and as an active agent in chemical processing. ("Alumina" Britannica) Although the naturally occurring corundum, ruby and sapphire are sometimes also referred to as alumina, but the proper use of the term is limited to the material that is derived from bauxite and employed in the production of aluminum, industrial ceramics, and chemical processing. In this paper, besides briefly covering the background information/ history of the material, we will describe its chemical and physical properties, its manufacturing process (the Bayer process) and its applications or uses.
