The inclusion of the InChI or SMILES codes as a one-sentence answer allows web-based classroom response systems to provide instant feedback to some of the most typical drawing-based questions asked in organic chemistry courses. This paper discusses the implementation and scope of this strategy using smartphones as the only hardware requirement.

The use of Moodle quizzes as a continuous assessment and an integral part of the educational methodology in higher education has been analyzed in a case study of physical chemistry subject. Two types of quiz designed with different item types and different settings, called basic quiz (BQ) and thematic block quiz (TBQ), were elaborated making use…

Acid-base chemistry, and in particular the Lewis acid-base model, is foundational to understanding mechanistic ideas. This is due to the similarity in language chemists use to describe Lewis acid-base reactions and nucleophile-electrophile interactions. The development of artificial intelligence and machine learning technologies has led to the…

The use of technology in assessment continues to evolve the field of educational measurement. This article reports on development and use of new accessible, technology-enhanced assessments designed to measure the three-dimensional science abilities of middle school students. The assessments were piloted with over 70 teachers and 8,000 students…

We present lessons learned from an ongoing attempt to conceptualize, develop, and refine a way for teachers to gather formative assessment evidence about classroom argumentation as it happens. The system--named DiALoG (Diagnosing Argumentation Levels of Groups)--includes a digital scoring tool that allows teachers to assess oral classroom…

Assessing students' participation in science practices presents several challenges, especially when aiming to differentiate meaningful (vs. rote) forms of participation. In this study, we sought to use machine learning (ML) for a novel purpose in science assessment: developing a construct map for students' "consideration of generality,"…

Two out-of-class formative assessments that have been developed and used in a General, Organic, and Biochemistry course are reported herein. The first assessment, called Daily Feedback, used the collaborative word processor, Google Docs. This assessment required students to place topics/objectives in one of three categories based on their level of…

The purpose of this study was to reveal the experiences of science teachers during the pandemic and their recommendations about the post-pandemic process. In the study, the "first period" referred to the period when the pandemic first appeared (the period between March-June 2020) and the "second period" referred to the…

Physics educators keep adding many skill developments to science and engineering students during their education as individuals and groups including critical thinking, conceptual understanding, problem-solving, mathematical implementation, computational implementation, etc. Here, we are discussing how to reach and analyse students' outcomes within…

The Computer has occupied a comprehensive coverage, especially in education scopes, including in learning-teaching processes, testing, and evaluating. This research aimed to develop computerized adaptive testing (CAT) to measure physics higher-order thinking skills (HOTS), namely PhysTHOTS-CAT. The Research Development used the 4-D developmental…

Effective assessment is an extremely important area of chemistry education. Typically tests measure students' knowledge of critical thinking skills, chemistry vocabulary, and application of concepts from one chapter to another. While it is relatively straightforward to measure concepts such as chemical vocabulary and algorithmic problem solving…

When teachers first wrap their heads around scientific modeling, it can be a bit tricky to distinguish scientific models from diagrams and three-dimensional models. If a fifth grader draws and labels a food web, it's a model. Right? Not necessarily. When creating a model, students should be representing a system inspired by an inquiry or…

The COVID-19 outbreak has altered chemistry laboratory instruction and forced us to reconsider the balance between face-to-face and online teaching. Our students preferred face-to-face teaching (score 4.1/5 on a Likert-like scale) to virtual laboratory exercises (3.4/5) despite the fact that their performance score was actually lower in…

The COVID pandemic forced many higher education institutions to pivot and switch to an online learning environment with minimal preparation. This transition was put in place during the middle of the spring semester, in March. During this transition, instructors had to quickly learn the tools of online teaching, navigate platforms like Webex and…

This qualitative study sought to explore Malaysian novice chemistry teachers' experiences in teaching mixed-ability students during their teaching practicum, focusing on their instructional strategies for dealing with those learners in the class. The researchers employed purposive sampling to select 12 trainee teachers to be involved in…
