Assessment plays a critical role in instruction and curriculum. Existing literature on instructors' assessment practices and related factors has been intensively focused on primary and secondary education. This study extended the contexts of previous literature to post-secondary chemistry education by exploring general chemistry instructors'…

Providing students with feedback on their performance is a critical part of enhancing student learning in chemistry and is often integrated into homework assignments, quizzes, and exams. However, not all feedback is created equal, and the type of feedback the student receives can dramatically alter the utility of the feedback to reinforce correct…

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…

What and how instructors assess understandably impacts student learning and performance in undergraduate science courses. However, there is limited research on the ways in which assessment practices might be altered to combat inequitable outcomes in these settings. Here we characterize the nature of assessment questions in one second-semester…

Knowledge space theory (KST) is a mathematical framework for modeling and assessing student knowledge. While KST has successfully served as the foundation of several learning systems, recent advancements in machine learning provide an opportunity to improve on purely KST-based approaches to assessing student knowledge. As such, in this work we…

This study developed and implemented a learner-centered assessment named Creative Exercises (CEs) in introductory chemistry courses at a four-year university and a two-year community college. CEs were developed and implemented as an intervention for treatment groups. The control groups only used traditional assessments such as multiple-choice and…

The present paper offers a competency-based approach to evaluate high school laboratory skills during a chemistry course. The "Secretaría de Educación Pública" (Mexico's Ministry of Education) has identified experimental sciences specific competencies that are to be established in high school. This study investigated the following…

The Canadian Remote Sciences Laboratories (CRSL) website (www.remotelab.ca) was successfully employed in a study of the differences in the performance and perceptions of students' about their learning in the laboratory (in-person) versus learning at a remote location (remote access). The experiment was completed both in-person and via remote…

The purpose of this research is to design assessment instrument to evaluate science generic skill (SGS) achievement and chemistry literacy in ethnoscience-integrated chemistry learning. The steps of tool designing refers to Plomp models including 1) Investigation Phase (Prelimenary Investigation); 2) Designing Phase (Design); 3)…

This article summarises the practical requirements for new science A-levels in biology, chemistry and physics for first teaching from September 2015. It discusses the background to how the new approach was reached and how OCR has seen this taking shape in our assessment models. The opportunities presented by this new approach to practical…

"Visible teaching and learning" is an educational philosophy that makes the processes and endpoints in a classroom highly visible and understandable to all involved. This was translated into a series of lesson "roadmaps" for a group of chemistry students studying rates of reaction and reaction energetics. Their end-of-unit…

In this study, two groups of 11th grade chemistry students (n = 210) performed a sequence of hands-on and virtual laboratories that were progressively more inquiry-based. One-half of the students did the laboratory sequence with the addition of a teacher-led discussion connecting student data to student-generated visual representations of…

We developed an online exam to diagnose students who are underprepared for college-level general chemistry and implemented a program to support them during the general chemistry sequence. This transition program consists of extended-length recitations, peer-led team-learning (PLTL) study groups, and peer-mentoring groups. We evaluated this…

Education is one of the fundamental and critical indices of development in a nation or an individual. The challenges post by our fast changing and dynamic world informed the need to constantly access the educational process so as to guarantee quality of educational assessment; several factors have been identified to be responsible for students'…

It is a common complaint among teachers that students forget what they have learned soon after taking a test. The phenomenon is seen in both secondary and undergraduate chemistry courses. This study examines the length of time after a test that students in three different chemistry courses (undergraduate nursing, nonscience majors, and high school…
