Advancing integrated STEM learning through engineering design: Sixth-grade students’ design and construction of earthquake resistant buildings

ABSTRACT

As part of a 3-year longitudinal study, 136 sixth-grade students completed an engineering-based problem on earthquakes involving integrated STEM learning. Students employed engineering design processes and STEM disciplinary knowledge to plan, sketch, then construct a building designed to withstand earthquake damage, taking into account a number of constraints. On testing, students redesigned to build an improved structure. Using a framework of design processes, we report on the students' capabilities in planning, creating annotated sketches, and transforming these into 3D models. An understanding of core STEM concepts was apparent in their responses, including shape properties, stability, rigidity, balance, strength, and engineering techniques. Group problem solving involved moving iteratively between design phases, frequently revisiting problem scoping, being cognizant of the problem goal, boundaries and constraints, and appreciating design sketches as guiding constructions. Students were also observed to consider a number of problem components simultaneously, indicating their capabilities in handling the complexity of the task.     

Individual Differences in Social Media Use for Information Seeking

This study investigated which social media platforms are used as information sources, and for what purposes. It also examined how user characteristics are related to the use of different platforms. A Web-based survey was used to collect data from undergraduate students. Responses from more than 800 students showed that most of the social media platforms are used as information sources, where wikis, user reviews, and media-sharing sites emerged as the top platforms. The purpose of use varied across platforms. T-test and ANOVA results also revealed individual differences. Significant differences in gender, class level, academic discipline, and Big Five personality traits were found in the frequency of information seeking using different platforms and also in the purpose of use. Study findings have implications for information literacy (IL) education and information services. Because many students are actively using social media platforms for a variety of information-seeking purposes, it is suggested that IL programs embrace social media as potential information sources and offer effective strategies for using and evaluating these increasingly popular social media sources.     

Influence of body composition on physiological responses to post-exercise hydrotherapy

This study examined the influence of body composition on temperature and blood flow responses to post-exercise cold water immersion (CWI), hot water immersion (HWI) and control (CON). Twenty-seven male participants were stratified into three groups: 1) low mass and low fat (LM-LF); 2) high mass and low fat (HM-LF); or 3) high mass and high fat (HM-HF). Experimental trials involved a standardised bout of cycling, maintained until core temperature reached 38.5°C. Participants subsequently completed one of three 15-min recovery interventions (CWI, HWI, or CON). Core, skin and muscle temperatures, and limb blood flow were recorded at baseline, post-exercise, and every 30 min following recovery for 240 min. During CON and HWI there were no differences in core or muscle temperature between body composition groups. The rate of fall in core temperature following CWI was greater in the LM-LF (0.03 ± 0.01°C/min) group compared to the HM-HF (0.01 ± 0.001°C/min) group (P = 0.002). Muscle temperature decreased to a greater extent during CWI in the LM-LF and HM-LF groups (8.6 ± 3.0°C) compared with HM-HF (5.1 ± 2.0°C, P < 0.05). Blood flow responses did not differ between groups. Differences in body composition alter the thermal response to post-exercise CWI, which may explain some of the variance in the responses to CWI recovery.     

Steps for Applying the Complex Dynamical Systems Approach in Educational Research: A Guide for the Perplexed Scholar

Abstract

In this commentary, we propose a framework for applying the Complex Dynamical Systems (CDS) approach in educational research. Drawing on the conceptual articles in the special issue for ontological, theoretical, and methodological principles, and on the empirical articles for examples of these principles’ application, we suggest six interdependent steps for researchers who seek to pursue educational research from the CDS approach: (1) Conceptualizing the phenomenon as a CDS; (2) Defining a theory of the relevant CDS level; (3) Generating a CDS research goal and question; (4) Selecting a CDS corresponding methodology for data collection and analysis; (5) Interpreting the findings as a CDS; and (6) Disseminating the knowledge to relevant audiences and participating in a CDS scholarly community. We end the commentary with several of the promises and challenges of applying the CDS approach in educational research.     

Mathematical knowledge for teaching teachers: knowledge used and developed by mathematics teacher educators in learning to teach via problem solving

In this study, we report on what types of mathematical knowledge for teaching teachers (MKTT) mathematics teacher educators (MTEs) use and develop when they work together and reflect on their teaching in a Community of Practice while helping prospective primary teachers (PTs) generate their own mathematical knowledge for teaching in learning mathematics via problem solving. Two novice MTEs worked with an experienced MTE and reflected on the process of learning to teach via problem solving and supporting PTs in developing deep understandings of foundational mathematical ideas. Taking a position of inquiry as stance, we examined our experiences teaching mathematics content courses for PTs via problem solving. We found that all of the MTEs used and developed some MKTT through (a) understanding and deciding on the mathematical goals of both the individual lessons and the two-course sequence as a whole, (b) choosing and facilitating tasks, and (c) using questions to scaffold PTs learning and engage them in mathematical processes such as making conjectures, justifying their reasoning, and proving or disproving conjectures.     

What Happens When Learning Takes Place?

When asked "What happens when learning takes place?" most people, including those involved in education, find it difficult to provide a satisfactory answer. Nevertheless, assumptions about what happens have a bearing on what we (as learners, educators, researchers, and policy-makers) do, and on our answers to other questions about learning, teaching, and education. The paper addresses the title question on the basis of an analysis of the logic of learning. The approach is philosophical rather than physiological or sociological, and draws on the work of Karl Popper. The outcome is a radical, universally applicable theory which identifies a set of features common to all processes in which learning can be said to take place. The theory has significant implications for educational policy and practice: it draws attention to factors which inhibit learning and is suggestive of ways in which learning can be promoted.     

Storyline and Associations Pyramid as methods of creativity enhancement: Comparison of effectiveness in 5-year-old children

This article presents the results of a study comparing the originality, the length, the number of neologisms and the syntactic complexity of fairy tales created with “Storyline” and “Associations Pyramid.” Both methods were developed to enhance children's language abilities and their creative thinking. One hundred twenty eight 5-year-old children were asked to tell stories using either the “Storyline” (SL) or the “Associations Pyramid” (AP) method during four routine class activities. Participants worked in 14 groups, five participants per group. The results showed that stories developed with SL and AP methods are comparably original, however more original than stories developed individually.     

The Adolescent Relational Dialectic and the Peer Roots of Adult Social Functioning

The long‐term import of a fundamental challenge of adolescent social development—establishing oneself as a desirable peer companion while avoiding problematic behaviors often supported within peer groups—was examined in a community sample of 184 adolescents, followed from ages 13 to 23, along with parents, peers, and romantic partners. The dialectical nature of this challenge appeared in findings that autonomy vis‐à‐vis peer influences predicted both long‐term success avoiding problematic behavior but also more difficulty establishing strong adult friendships. Conversely, being a desirable peer companion in adolescence predicted more positive adult relationships but also greater alcohol use. Adolescents who established themselves as both desirable companions and as autonomous vis‐à‐vis peers were rated as most successful by their parents at age 23.     

Student perspectives of engagement in learning in contemporary and digital contexts

ABSTRACT

Increasing significance has been ascribed to student engagement, as a measure of success of both teachers and programs. However, since users of the term commonly tend not to explain, rationalise or problematise their understanding of engagement, its value to understand or transform learning may be limited. While clarification has occurred in conceptual work, there is a lack of empirical work that extends beyond understandings of engagement-as-behaviour, as well as insufficient work exploring what students understand engagement to be. Further, much work on engagement is rooted in physical campuses and face-to-face delivery, which represents an incomplete picture of how students actually engage in study. This article investigates student perceptions of engagement in two blended learning Initial Teacher Education programs. It offers a critical discussion of how research can be re-considered in light of changing learning contexts and changing understandings of ways to investigate engagement. The findings of this study support previous work that found multiple levels and meanings of student engagement exist. New complex and multidimensional models of engagement are proposed, which can open new possibilities for designing studies and analysing findings. This article argues that including and questioning physical, virtual and political contexts and power, affect, relationships, linearity and essential measurability are important features of new models of engagement.
