The curriculum for undergraduate Agricultural Engineering does not usually include much laboratory practice. In order to address this, here we propose the design of a practical class on legume-rhizobia symbiosis, using an interdisciplinary approach that takes elements from botany, agriculture, and microbiology. The students perform an assay to…

'A lack of prior knowledge in the other discipline' is often given by geoscience instructors to explain why students struggle to apply knowledge from other disciplines to the Earth. We examine this assumption by considering the disciplinary crossing of buoyancy (physics) to isostasy (geoscience). We investigate the teachers' perspective through…

Numerous studies have proven the learning benefits of concept maps in science subjects, particularly for students with low prior knowledge. There is a scarcity of research dedicated to the examination of chemistry courses at the university level, and the findings pertaining to academic performance in that subject exhibit a lack of consistency.…

Undergraduate courses on the nature of science (NOS) often involve teaching a set of core elements. Without extensive unpacking and reflection, the complexity of those NOS elements could be easily misinterpreted and oversimplified by the students. Our paper will explain how we teach our Hong Kong university students the NOS by introducing…

Preparatory or bridging courses are widespread and have a long tradition at universities. They are designed to increase students' academic success -- in particular of students with low prior knowledge -- and to reduce dropout rates. However, critics of these short and compact bridging courses complain that preparatory courses are not able to fill…

Symbols are a cornerstone of the written language of physics and mathematics but inconsistencies in their use pose a challenge to students. This article reports on interviews held with first-year undergraduate physics students, focused on their early experiences with symbols in university physics. Students reported being confused by the symbolic…

Both attitude and previous experiences play a large role in shaping a student's approach to and achievement in a given subject. Similarly, students' enjoyment of their learning experiences is an important factor in determining their retention in their course of choice. Here, we explore the attitudes toward the study of chemistry amongst a cohort…

The objective of this work was to evaluate the implementation of a metavisual strategy for students to revise and self-regulate concepts arising in a study of a chemical reaction between ions. For this purpose, two chemistry education undergraduate students at a Brazilian public university carried out an investigative activity, involving…

This paper examines the relationship between mathematics anxiety and students' performance, gender, length of the studies and postponed calculus courses in scientific faculties. The data were collected from Calculus 2 students at the Hashemite University during the academic Year 2015/2016. The student sample consisted of 179 students with both…

Students' responses to energy & momentum (EM) concepts were investigated. EM concepts are fundamental and crosscutting in physics. A standardized Energy and Momentum Conceptual Survey (EMCS) test were used to collect quantitative data from 108 first year science students enrolled in a university in Ethiopia. Concentration analysis was used to…

In this explorative study, a diagnostic test on diffusion and osmosis (DTDO) was developed and used to assess pre-degree students' conceptual understanding and application of diffusion and osmosis in biology. The 25-item DTDO is a two-tier test--adapted from Odom and Barrow's (1995) Diffusion Osmosis Diagnostic Test (DODT)--developed and validated…

This study investigates the knowledge acquisition of biology and physics freshmen students with special regard to differences between high school (HS) high performing and low performing students. Our study is based on a prior knowledge model, which describes explicit knowledge as a composite of four knowledge types: knowledge of facts, knowledge…

Visualizations and visual models are of substantial importance for science learning (Harrison and Treagust, 2000), and it seems impossible to study chemistry without visualizations. More specifically, the combination of visualizations with text is especially beneficial for learning when dual coding is fostered (Mayer, 2014). However, at the same…

In Australia, a significant number of students enrol in first-year university biology without the benefit of high school biology. In order to help students support each other, the authors of this paper (a central unit academic developer and a biology coordinator of first-year biology) created a classroom activity that facilitated the distribution…

This study aims to identify students' misconceptions regarding covalent bonds. Seventy-seven graduate students in the middle of Indonesia participated in the study. Data were collected in three stages. First, misconceptions were identified by using the Semi Open Diagnostic Test. Ten students who experienced the worst misconceptions were…
