Soft rot diseases cause crop losses all over the world. These losses can have large economic impacts and threaten international food security. Soft rot bacterial pathogens produce pectolytic enzymes that attack the pectin around plant cells resulting in smelly, wet, and mushy tissue maceration. Once symptoms are visible, the crop cannot be used or…

For many students biochemistry is a demanding course because they are expected to apply previously learned foundational concepts to new biological contexts. These foundational concepts serve as a scaffold onto which to build threshold concepts such as the physical basis of interactions. Unfortunately, many students possess misconceptions or gaps…

This paper discusses the significance of model-based teaching on the topic of ionic and metallic bonding in Year 12 Chemistry in a New Zealand secondary school. Based on the conceptualization of the sub-macro level understanding of the bonding structure and properties of ionic and metallic compounds, models and drawings were used as an effective…

Understanding chemical models can be challenging for many university students studying chemistry. This study analysed students' understanding of molecular structures using the Lewis structure as a model, and examined what hinders their understanding. We conducted pre- and post-tests to analyse students' conceptions and changes in them. The…

The abstractness of the chemistry concept can be understood easily through chemistry learning using multiple representations. This article used the Systematic Literature Review (SLR) method to review eleven articles published from 2012 to 2021 and focused on chemistry learning using various representations. The articles are systematically obtained…

This study aimed to determine the extent of pre-service science teachers' (PTS) process and materialistic understanding of sound concept and the role of their task value beliefs in their scientific conception of sound. With this aim, the Sound Concept Inventory Instrument (SCII) was translated and adapted to Turkish. The SCII was administered to…

Background: Being able to think independently is a must for students to construct new knowledge in their minds. Self-explaining is a constructive learning strategy that encourages students to think for themselves and to make inferences that go beyond the given information. The Self-explain--Discuss--Re-explain (SDR) strategy adapted from…

The proper learning strategy, mainly in cellular respiration topic, can be determined as mapping teacher candidate's prior knowledge was done. This study aimed to get the profile of prior knowledge of teacher candidates in cellular respiration topic. This survey research used four-tier diagnostic test as data collection instrument. The number of…

The purpose of this study was to investigate both the individual and relative effectiveness of two conceptual change interventions, gender and their interactions on preservice science teachers' conceptual understanding and their misconceptions in mechanical waves. The interventions are conceptual change texts enriched with concept cartoons (CCTCC)…

The primary focus of this education leadership portfolio is to reconstruct lessons on chemical reaction concepts for teachers to use and reach all learners of chemistry in Cecil County Public Schools. As a high school chemistry teacher, I have observed that student enrollment in chemistry is relatively low, and students show little enthusiasm…

Educational researchers and teachers are well aware that misconceptions--erroneous ideas that differ from the scientifically accepted ones--are very common amongst students. Daily experiences, creative and perceptive thinking and science textbooks give rise to students' misconceptions which lead them to draw erroneous conclusions that become…

Conceptual change instruction recognizes that students bring personal, or naive, conceptions to the classroom, which they use to explain their world, interpret situations, and create meaning (Driver et al. 2007). But what happens when students' personal conceptions are inconsistent with experts' views of scientific knowledge? Even after direct…

Within the field of education, there has been an increasing recognition of the importance of formative assessment and of structural knowledge. In an effort to fill needs in each of these areas, this article describes an innovative feedback strategy intended to improve students' structural knowledge. Twenty-four high school physics students were…

The aim of this study is to investigate Emiratii high school students' understandings of stoichiometry, their use of metacognitive strategies, and the influence of students' use of metacognitive strategies on their understandings of stoichiometry. Two instruments were used in this study, the first to measure students' understandings of…

Pedagogical strategies have been experimentally applied in large-enrollment biology courses in an attempt to amplify what teachers do best in effecting deep learning, thus more closely approximating a one-on-one interaction with students. Carefully orchestrated in-class formative assessments were conducted to provide frequent, high-quality…
