One of the more difficult concepts introduced in the first-year undergraduate course, general chemistry, is that of chirality. Typically, left and right hands are the common, macroscopic objects of reference used to demonstrate the quality of being nonsuperimposable, followed by the use of a mirror and molecular models, to illustrate molecular…

Rainfall is a key process in the water cycle, the most structured scientific knowledge about water movement on Earth. Nevertheless, despite being a common topic covered in school science, it entails several cognitive difficulties for young children. This study uses a pictorial task and semi-opened questions to examine primary (11/12 years old) and…

A deep understanding of mechanical waves is crucial for students to succeed in studying many advanced physics topics. Studies in existing literature have revealed that students often have widespread difficulties and misconceptions on wave propagation. This research develops and applies a conceptual framework model to examine students'…

An experimental approach to chemistry is a more meaningful way to learn than the use of textbooks alone. Working in the laboratory helps students understand basic concepts through their active engagement. Here, we present a series of inexpensive and environmentally friendly laboratory exercises on acid-base equilibrium. Their difficulty level is…

The aim of the present study is to explore on the alternative conceptions of impetus theory and projectile motion of students with high functioning autism spectrum disorders and compare them with those of typical development. For this purpose, an experimental investigation was conducted with 19 students with high-functioning autism (age range:…

The aim of this online workshop is to familiarize biomedical faculties students with the principle of RT-PCR method. The following assumption is made, students participating in the workshop: (1) are already familiar with the principle of PCR reaction; (2) can distinguish PCR from RT-PCR; (3) know the basic possibilities of using the above…

A new project-based laboratory (PJBL) was developed for general chemistry students to tackle the steps involved in chemical water quality analysis using an accessible, real-world hydrologic system (the lakes of the Lower Grand Coulee, Washington). This PJBL was developed in a joint general chemistry and environmental geology course by a…

Reasoning about organic chemistry reaction mechanisms requires engagement with multiple concepts and necessitates balancing the relative influence of different chemical properties. A goal of organic chemistry instruction is to support students with engaging in this type of reasoning. In this study, we describe our use of case comparison problems…

We present a drawing discovery lab that crosscuts multiple disciplines in biology and links concepts in genetics and evolutionary thinking to enhance understanding of the genotype-to-phenotype transformation. These combined concepts are also linked to ecological frameworks in nature through the model of biological plasticity. Students and teachers…

This research focuses on students' higher-order cognitive skill (HOCS)-oriented learning to construct effective hierarchical thinking abilities in their chemical particulate nature of matter. For in-depth knowledge and profound understanding, this research deals with students' positive developments towards HOCS with a special guidance to Marzanos'…

Molecular symmetry is a topic that requires mental manipulation of molecules when searching for symmetry elements and their corresponding symmetry operations. Such mental activities are difficult for students in a traditional classroom where only definitions and demonstrations are provided. Therefore, an exploration-based activity was developed to…

Rapidly occurring advancements in molecular genetics, such as recent developments in epigenetics, are challenging traditional genetics as it is taught at schools. For example, the adoption of epigenetics--which provides molecular mechanisms for the environment to directly alter phenotypic variation--would mean that pivotal tenets in genetics…

Global connections are an important part of the elementary classroom as they help students develop empathy through interactions while allowing them to apply classroom learning to the outside world (Suvansri 2016). Through Partnering with a classroom in another country the author hoped to create curiosity while helping students build a global…

Practical work as observation and experimentation are vital parts of science education. One way to accomplish this is by applying inquiry-based learning in laboratory activities. Inquiry enhances the development of scientific skills as well as the learning of the scientific concepts. In the present article, a laboratory activity was developed to…

Misconceptions are a major problem in learning biology and their emergence may potentially increase during online lectures. The purpose of this study was to identify student misconceptions in Department of Biology Education, Universitas Muhammadiyah Malang during online biochemistry lectures. This quantitative study involved 39 respondents.…
