This study aimed to determine the effectiveness of using an interactive e-module to reduce students' misconceptions on salt hydrolysis material at grade XI in senior high school. This study implemented a pre-experiment with one group pretest-posttest research design, which utilized one class as the experimental class. Samples were selected by…

General Chemistry is a course where students are expected to nurture the development of their fundamental concepts in chemistry. Students begin general chemistry with alternative conceptions about the topics and fragmented knowledge structures. Majority of students who successfully complete the general chemistry course sequence continue to hold…

This study investigated the perceptions and quality of argumentative and summary writing of the Pre-service Science Teachers (PSTs) who participated in a knowledge generation approach to learning, which is known as the SWH approach, and who had had experience with it across different time periods. A total of 41 PSTs were divided into three groups…

Lewis structures are a very important, foundational concept in chemistry. Students usually acquire this knowledge in General Chemistry and need to review it in preparation for Organic Chemistry. However, many students find the task of drawing Lewis structures to be challenging, and not all instructors can budget enough time in class to review this…

Students in advanced undergraduate chemistry laboratories are required to undertake a wide range of complex and multistep syntheses and analytical procedures, and prospective employers of chemistry graduates seek students with proven skills in these areas. Our approach has been to use video resources which are made available to students both ahead…

The 100th anniversary of the first article (published in 1921) examining student success and the high school to university transition in chemistry provides an excellent opportunity to consider what has -- and has not -- changed in chemistry education. This review details the development and findings of chemistry education research specifically as…

IUPAC nomenclature competence (INC)--defined as the ability to name chemical structures using IUPAC rules and draw structures from IUPAC names--is considered a foundational skill in the training of professional chemists. For students of non-European language background, the challenge of acquiring INC is often complicated by the fact that IUPAC…

General chemistry students need to understand the concept of intermolecular forces and use them to predict the properties of materials. To do this, they must create symbolic representations of molecules, relate these to physical observations, and explain them using submicroscopic theoretical constructs. When these concepts are taught separately,…

While there have been an increasing number of evidence-based instructional strategies propagated, less literature exists on how to propagate a curriculum. This paper is meant to present how the theory of "Design-Based Implementation Research" (DBIR) can be used as a framework to propagate such innovative curricula. DBIR is a research…

The International Year of the Periodic Table of Chemical Elements in 2019 provided a perfect opportunity to implement community engagement activities that repositioned the public image of chemistry, from one detrimentally linked to the long-term impacts of its previous achievements such as plastic waste and polluting industrial plants to one that…

Structure-property reasoning (SPR) is one of the most important aims of chemistry education but is seldom explicitly taught, and students find structure-property reasoning difficult. This study assessed two design principles for the development of structure-property reasoning in the context of demonstrations: (1) use of a POE task…

Among the new educational tools and new ways of teaching/learning of the last 20 years, educational approaches based on constructivism are of great interest because they offer the possibility for students to build scientific concepts from experimental observations. Cooking is truly a universal topic--it can be considered a true multidisciplinary…

Online teaching and learning as an electronically supported approach relies mainly on the Internet as the medium for knowledge transmission. The utmost efforts are being made so that learning will be possible, even during the time of the COVID-19 pandemic, while also maintaining academic integrity. In this paper, we discuss the major steps taken…

The course design "Training OC" for training the application of basic concepts consists of four topics: formula language, structure-property relations, reaction mechanisms, and complex tasks that the students should solve with the conceptual knowledge they acquired in the first three topics. A main goal of the course was to enable the…

Over 40 years of research, concept maps have shown that they are beneficial for learning. However, much of this research has been conducted in laboratory settings. Although there are a few studies conducted in the classroom, there is little understanding of the instructional efficacy of using different types of concept maps. In a between-subjects…
