In this article, we describe a fully computational laboratory exercise that results in an increase of students' understanding of what quantum chemical geometry optimization calculations are doing to find minimum energy structures. This laboratory exercise was conducted several times over multiple years at a small private undergraduate institution,…

pH buffers are used extensively in research and industry making them an important chemistry topic for students to learn. This qualitative study uses the phenomenographic method and a resource theoretical framework to provide the first insights into how students approach conceptual buffer problems. Three scaffolded buffer question sets were…

John Dewey is well-known for claiming that school education is all about developing the ability to think. There is nothing else for schools to do so far as students' minds are concerned. Thinking is not only the aim of education for Dewey, however, but the means of achieving it. This is not because it is the method to be preferred. Rather, as…

In this report we show an investigation of how high-school students learn strategies to find intermediate numbers in an interval to understand the property of numerical density. Research has shown that some high-school students have difficulty in understanding this property. To mitigate this difficulty, we proposed a Hypothetical Learning…

This research contributes to the need to identify and expand learning environments that encourage undergraduate students to develop collaborative work skills and apply their classroom knowledge to solve real-world problems. Using qualitative methods, we examine the effects of the interaction between two teams of students when solving a…

This is the first of four columns by Tim Erikson which introduces us to the Common Online Data Analysis Platform (CODAP). CODAP is a free, web-based software tool that your students can use for many types of tasks. This first column shows how CODAP can be used for mathematical modelling and where it might fit with the "Australian Curriculum:…

This was second year's research in developing a biology learning module of ecosystem material that promotes mobile android-based local region potentials, after first year conducted a field examination on android e-module and limited testing in East Lombok Regency, West Nusa Tenggara and Sleman Regency, D.I. Yogyakarta. The second-year research…

Global education is a cross curricular discipline, originating in the 1970s and 1980s, developed for schools by international educators in the United Kingdom, Europe and North America. One definition describes it as "education which promotes the knowledge, attitudes and skills relevant to living responsibly in a multicultural, interdependent…

How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

Academic and behavior problems co-occur in students at rates higher than chance, with rates ranging from 10% to 50% (Darney, Reinke, Herman, Stormont, & Ialongo, 2013). Such comorbidities lead to an increased risk for negative symptoms, including depression, substance use, violence, and delinquency (Darney et al., 2013). Combined…

This study aims to determine whether there was differences effect in improving student's critical thinking skills (1) between students who get Problem-based Learning, Mathematical Problem Posing, and conventional learning, and (2) based on gender differences. This study used a quantitative method with the pre-test-posttest two treatment design.…

This study aims to examine the effect of Problem Based Learning learning strategies, cognitive styles, and their interaction on students' problem-solving ability in social studies subjects. The type of this research is a quasi-experiment with nonequivalent control group design. The number of samples used was 120 students consisting of 60 students…

In this work we present the design of a computer-based environment aimed at engaging primary school children in argumentative practices while solving a story problem. Argumentation has been regarded from two points of view, both as a process and as a product. Students, using the collaborative tools offered by the platform, co-constructed shared…

This study analyzed the relative importance of different cognitive abilities for solving complex mathematical word problems (CWPs)--a demanding task of high relevance for diverse fields and contexts. We investigated the effects of spatial, verbal, numerical, and general reasoning abilities as well as gender on CWP performance among N = 1282…

The main goal of this research is to study the effect of modelling with system dynamics on learning. Specifically, this research studies if using inductive or deductive learning methods applied during modelling with system dynamics has any effect on problem solving skills of students. This research has three other goals: Firstly, the successful…
