Global environmental change coupled with increased demand for food and competition for diminishing water places the issue of disaster risk management high on the global political agenda. Drought is one of the most complex natural hazards, affecting natural resources and human development recurrently. Drought affects agricultural production globally, triggering significant food and health insecurity and habitat loss through land degradation and desertification. While the consequences of droughts can usually be predicted, preventive action is frequently absent or insufficient to prevent serious impacts in many regions of the world. We believe that lack of a common understanding of what drought is stands in the way of cohesive anti-drought action. This paper examines drought definitions emerging from influential scholarship, practitioners' discourse and multilateral policy processes that emphasise diverging aspects of the phenomena of dry periods, including the source, duration, spatial extent, impact and affected stakeholders. This paper begins by examining the concepts of hazard and disaster. It then explores the various perceptions associated with drought and the problems posed by inconsistency in definitions. It concludes that a common conceptual understanding of drought is essential for effective action to address the growing need for reliable food supply, poverty alleviation and increased agricultural productivity globally.

Standardized assessment of content knowledge for STEM (Science, Technology, Engineering, Mathematics) topics is pervasive in both K-12 and postsecondary institutions. Yet, most instruments are developed with little to no validation for students with learning disability (LD), attention deficit hyperactivity disorder (ADHD), and autism spectrum disorder (ASD). In this study, we evaluate the effectiveness of new test instruments designed to assess conceptual understanding of statistics content and the extent to which construct-irrelevant factors, such as language processing, influence the performance of students with disabilities. Generalized linear mixed-effects modeling was used to identify the factors that were predictive of student performance. Results indicate that the average sentence length in word problems was uniquely predictive of student performance on emerging assessments of conceptual understanding. The results provide new evidence of the barriers facing students with disabilities on emerging tests of conceptual knowledge. A general framework for measuring the impact of these barriers and the effectiveness of accommodations is discussed.

Abstract Product dissection, in either physical or virtual form, has been found to be an effective learning tool. With the rapid growth of technology, effective virtual education tools have the potential to continue increasing in value. Although physical product dissection is often implemented in the classroom, there are some limitations to employing these tools. One such limitation is the inability to see into a product and view the internals of a product while it is functioning. Recent research has found that students who dissect physical or virtual products have similar conceptual understanding of products after dissection. Although there are promising findings for virtual dissection, there is still room for improvement in these virtual environments to enable better understanding of products. One way this may be possible is through the addition of animations, which show the functions of the internal components in a product, a capability that is currently not offered in virtual product dissection tools. These animations have the ability to show how a product works in ways unobtainable through physical product dissection and currently unavailable in virtual product dissection. Therefore, this research aims to explore the impact that animation in virtual product dissection has on learning and cognitive load for engineering students.

Research has demonstrated the positive impact of active learning on students’ learning outcomes, particularly in science, technology, engineering and mathematics (STEM) fields. However, few studies have explored the impact of active learning via problem-based collaborative games in large mathematics classes in the context of Asian tertiary education. This study assesses the effects of active learning on students’ learning outcomes using class test scores and the calculus concept inventory (CCI) to test the conceptual understanding of the basic principles of differential calculus, in a first year calculus course in Hong Kong. Three hypotheses were tested to determine the effects of game-based collaborative learning on learning mathematics among students. Active learning through a problem-based collaborative learning methodology was employed, using Kahoot!, a game-based learning platform. Results supported all three hypotheses, demonstrating a statistically significant increase in students’ conceptual understanding and examination performance, based upon their individual perceptions of active engagement and time spent in active learning. Our results indicated that active learning “levels the playing field”, in the sense that students with less pre-requisite background knowledge, using a problem-based collaborative learning methodology, were relatively more inclined to catch up or even exceed the performance of students with a stronger prerequisite background knowledge, at the end of the course.

The design process and implementation of a hands-on unit on fractions in the sixth grade. The unit uses pattern blocks to help students develop conceptual understanding of fractions. Student misunderstandings and outcomes are presented, as well as the teacher's perspective on the impact on her classroom.

  The term numeracy is used widely in schools today and brings with it the expectation that students will be taught both how to do the mathematics, alongside an understanding of the concepts associated with the procedural application. One issue, which has arisen with the terminology ‘numeracy classroom’, is how to best support teachers to enhance their teaching of mathematics to allow this understanding to occur. This article stems from a larger research study that analysed the professional knowledge of teachers when teaching numeracy, and the impact their mathematics knowledge and procedural application had on children’s learning. This article presents observations of three teachers teaching a multiplication lesson (the first in a series of lessons over a six-week period) as they developed their students’ understanding of the mathematical concepts associated with the interpretation of the multiplication symbol. An analysis of the findings shows when the teachers used manipulatives, related word problems to the children’s lives, and promoted discussion in groups, a greater understanding of multiplication was apparent.

Purpose: The purpose of this study is to determine the impact of an Inquiry-based Flipped classroom model on the conceptual understanding and science process skills of junior high school students in the Philippines. Method: A two-group pretest/post-test design was conducted on 55 Grade 9 students for the study. One group received instruction using the flipped classroom format while the other group serving as control was taught in the conventional format. A Conceptual Understanding Test (CUT) and a Science Process Skills Test (SPST) were used to measure the impact of instruction on the two groups. Independent samples t-test was used to determine if there was a significant difference between the groups while paired samples t-test was conducted on both groups to determine if the groups improved significantly after a 7-week intervention. Linear regression was performed to determine if science process skills was a positive predictor of conceptual understanding. Findings: Inquiry-based flipped classroom did not make students perform better than the non-flipped inquiry-based learning environment in the Conceptual Understanding Test (CUT) and Science Process Skills Test (SPST) except on one biology topic (non-Mendelian Genetics) where the Flipped Inquiry Group scored significantly higher than the control in the CUT. Students’ science process skills positively predicted their conceptual understanding in biology. Significance: Inquiry–based flipped classroom can be as effective as the non-flipped inquiry-based instruction in improving students’ conceptual understanding and science process skills but can be made even more effective depending on the content, the manner the content is uploaded and the choice of LMS for uploading the online content. The study also showed the importance of science process skills in enhancing students’ conceptual understanding in biology.
