Investigating the optical properties of various chemical compounds using UV-vis spectrophotometers is an essential part of education in chemistry. However, commercial spectrophotometers are usually treated as "magic black boxes", where the dominant majority of optical elements are hidden "under the hood". This often limits…

Past research suggests that children, particularly those with autism spectrum disorder, with general behavioral inflexibility to objects, persons, and environments may be at risk for feeding problems. However, questions remain about whether feeding problems are better predicted by behavioral inflexibility or sensory sensitivity, and whether…

Recent research has begun to explore the specific social challenges experienced by persons with Tourette syndrome (TS); however, it does not specifically address the challenges that often arise interpersonally as part of people's communicative interactions and these interactions socially construct the individual and collective well-being of all…

Many individuals diagnosed with intellectual and developmental disabilities (IDD) are uncooperative during routine dental exams, leading to poor oral health in this population. Few studies have evaluated methodologies for preparing dental students and professionals to work effectively with patients diagnosed with IDD. In this study, experimenters…

Path analysis is used to provide estimates of the magnitude and significance of hypothesized causal connections among sets of variables displayed using path diagrams. It is an extension of multiple regression analysis and holds strength as a methodology as it allows researchers to assess both direct and indirect effects of multiple independent…

Although several studies have focused on why school climate is important, the timing of the collection of climate measures should be considered. This is of particular interest to schools that gauge school improvement efforts within a school year and are interested in how climate changes from the beginning to the end of the academic year. We show…

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 study explored negative emotional, behavioral, and academic performance outcomes for highly mobile students and potential protective factors. Participants were fourth and fifth-grade students (N = 647, 51% male) from three schools with low socioeconomic status, highly mobile student populations within a large, suburban school district in the…

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…

The study aims to compare the effectiveness of Guided Inquiry Learning (GIL) and Problem-Based Learning (PBL) model. A number of prior studies have implemented the GIL model for a limited area such as science. Similar to the PBL learning design, the previous studies that highlighted the application of GIL model was commonly targeted to find out…

Employing student-driven project work in a higher education setting challenges not only the way in which we understand students' learning and how we define the expected learning outcomes, it also challenges our ways of assessing students' learning. This paper will address this question specifically and illustrate with a case that highlights some…
