Spatial ability learning through educational robotics

Several authors insist on the importance of students’ acquisition of spatial abilities and visualization in order to have academic success in areas such as science, technology or engineering. This paper proposes to discuss and analyse the use of educational robotics to develop spatial abilities in 12 year old students. First of all, a course to introduce robotics to 6th grade primary school students was designed. The key intention was to prepare practical and motivating sessions in order to foster the students’ involvement in hands-on learning. Hence, during the sessions of the course, challenges were provided for the students, in order to develop their capabilities as proficient problem solvers. The teacher assisted and guided the students, and the students were encouraged to solve the problems by themselves, working in 3-members teams. The main goal of this paper is to discuss and analyse the potential usefulness of educational robotics to develop spatial abilities. To carry out the analysis, students were randomly divided into an experimental group (EG), which participated in the robotics course, and a control group (CG), which did not take part in the robotics course. The extensive existing literature for spatial ability evaluation was analysed and reviewed and a pre-test and a post-test were prepared for use in the research study. Initially, the spatial ability of both EG and CG students was assessed with the pre-test. Then, after finishing the robotics course, the same sets of students were tested with the post-test. An extensive analysis of the results is provided in the paper. Results show that the positive change in spatial ability of the participants in the robotics course (EG) was greater than change evident in the students who did not join the course (CG). The improvement was statistically significant. The results also show that the overall performance of the students depends on the instruments used to evaluate their spatial abilities. Hence, this study manifests clearly the importance of the selection of those instruments.     

The impact of problem-based learning strategies on STEM knowledge integration and attitudes: an exploratory study among female Taiwanese senior high school students

This study was designed to explore the effects of problem-based learning (PBL) strategies on the attitudes of female senior high school students toward integrated knowledge learning in science, technology, engineering, and mathematics (STEM). Content analysis and focus group methods were adopted as the research processes. Data and information about the STEM internet platform, an attitude scale and the contents of interviews were also collected for analysis. The subjects were 10th grade students at a girls’ senior high school who volunteered to organize teams for a Solar Electric Trolley Contest. A total of 40 students were grouped into 18 teams. The results of the study indicate: (1) that PBL strategies can be helpful in enhancing students’ attitudes toward STEM learning and the exploration of future career choices; (2) that the PBL teaching strategy helped to lead students step by step toward completing the contest’s mission and to experience the meaning of integrated STEM knowledge; (3) that not only that students can actively apply engineering and science knowledge, but also that students tend to gain more solid science and mathematics knowledge through STEM learning in PBL; and (4) that PBL can enhance students’ abilities and provide them experiences related to knowledge integration and application. Therefore, it is recommended that the curriculum at the girls’ senior high school include more content related to specialty subjects to enhance their technological capabilities. In addition, a learning mechanism should be offered to aid advisers or teachers in strengthening students’ integrated and systematic knowledge about STEM.     

How an integrative STEM curriculum can benefit students in engineering design practices

STEM-oriented engineering design practice has become recognized increasingly by technology education professionals in Taiwan. This study sought to examine the effectiveness of the application of an integrative STEM approach within engineering design practices in high school technology education in Taiwan. A quasi-experimental study was conducted to investigate the respective learning performance of students studying a STEM engineering module compared to students studying the technology education module. The student performances for conceptual knowledge, higher-order thinking skills and engineering design project were assessed. The data were analyzed using quantitative (t test, ANOVA, ANCOVA, correlation analysis) approaches. The findings showed that the participants in the STEM engineering module outperformed significantly the participants studying the technology education module in the areas of conceptual knowledge, higher-order thinking skills, and the design project activity. A further analysis showed that the key differences in the application of design practice between the two groups were (a) their respective problem prediction and (b) their analysis capabilities. The results supported the positive effect of the use of an integrative STEM approach in high school technology education in Taiwan.     

Robotics and STEM learning: students’ achievements in assignments according to the P3 Task Taxonomy—practice,problem solving,and projects

This study presents the case of development and evaluation of a STEM-oriented 30-h robotics course for junior high school students (n = 32). Class activities were designed according to the P3 Task Taxonomy, which included: (1) practice—basic closed-ended tasks and exercises; (2) problem solving—small-scale open-ended assignments in which the learner can choose the solution method or arrive at different answers; and (3) project-based learning—open-ended challenging tasks. The research aimed at exploring students’ working patterns, achievements in learning the course, and the impact of this experience on students’ motivation to learn STEM subjects. Evaluation tools included a final exam on factual, procedural and conceptual knowledge in the STEM subject learned in the course, class observations, interviews with the students, and administrating an attitude questionnaire before and after the course. Since the experimental class was quite heterogenic in regard to students’ prior learning achievements and motivation to learn, some of the students completed just the basic exercises, others coped well with the problem-solving tasks, and only a few took it upon themselves to carry out a complex project. However, all students showed high motivation to learn robotics and STEM subjects. In summary, robotics provides a very rich and attractive learning environment for STEM education. Yet, the realization of this potential depends largely on careful design of the course methodology and especially the students’ assignments in the class. One should recognize that often only some students are capable of learning a new subject on their own through project work, and these students also need to gain additional knowledge and skills before dealing with complex projects.     

Connecting the STEM dots: measuring the effect of an integrated engineering design intervention

Recent publications have elevated the priority of increasing the integration of Science, Technology, Engineering, and Mathematics (STEM) content for K-12 education. The STEM education community must invest in the development of valid and reliable to scales to measure STEM content, knowledge fusion, and perceptions of the nature of STEM. This brief report discusses the development of an instrument to measure student perceptions of the interdependent nature of STEM content knowledge in the context of a complex classroom intervention implemented in five Colorado high schools (N = 275). Specifically, cross-functional science, technology, engineering, and mathematics teams of high school students were formed to complete engineering design problems. Exploratory (pretest) and confirmatory (posttest) factor analyses indicated that a newly adapted scale to measure student perceptions of the interdependent nature of STEM content knowledge had possessed adequate model fit. Furthermore, analysis revealed a novel pattern of results for the intervention. Specifically, students with initially high perceptions of the interdependent nature of STEM sustained their high perceptions at posttest; however, students with initially low perceptions exhibited statistically significantly positive gains from pretest to posttest. Therefore, this intervention may work best with students who are at risk of losing interest in STEM disciplines. The implications of these research findings are discussed.     

The senior high school students’ learning behavioral model of STEM in PBL

The purpose of the study was to explore a learning behavioral model of project-based learning (PBL) for senior high school students in the context of STEM (science, technology, engineering, and mathematics). Using “audio speakers” as the project theme, a series of tasks were designed to be solved using STEM knowledge via an online platform and student group discussions. A total of 84 volunteer students from a senior high school and a vocational school in Pingtung, Taiwan, were divided into 21 groups. Text analysis and questionnaire survey were administered. Data sources were the participants’ information collected via the STEM online platform and the questionnaire survey regarding STEM in PBL. The findings of the study are as follows: (1) the learning behavioral model for STEM in PBL showed a positive influence on students’ behavior in the form of cognition and behavioral intentions. In addition, cognition and behavioral intentions were positively influenced by attitude. The overall model fit was positive and could effectively explain senior high school and vocational school students’ learning behavior as related to STEM in PBL; (2) according to the results of the analysis of STEM from the online platform, students displayed a positive attitude, attained integrated conceptual and procedural knowledge, and demonstrated active behavioral intentions through STEM in PBL. In addition, the students’ creative and organized project outcomes revealed the effects of their behavior.     

Engineering attitudes: an investigation of the effect of literature on student attitudes toward engineering

The growth of STEM career occupations is outpacing the college enrollment of STEM students in the United States. There have been many research projects investigating this issue. There has not however been a study which investigated the impact non-fiction literature has on student interest in studying STEM (specifically engineering) content. The purpose of this study was to investigate the change of student attitudes toward engineering after reading literature involving non-fiction engineering centric narratives. The study used a modified version of the PATT (Pupils Attitudes Towards Technology) called the TEAS (Technology and Engineering Attitudes Scale) to measure student attitude change. The students were high-school aged students in the United States (ages: 15–17) who were enrolled in an English Literature course. The students completed the TEAS before and after reading and studying two engineering and technology centric non-fiction books (The Boy Who Harnessed The Wind and October Sky). The data revealed that student attitude after reading and studying the two books did not statistically change.     

How school context and personal factors relate to teachers’ attitudes toward teaching integrated STEM

Integrated Science, Technology, Engineering and Mathematics (STEM) education is an emerging approach to improve students’ achievement and interest in STEM disciplines. However, the implementation of integrated STEM education depends strongly on teachers’ competence, which entails, among others, teachers’ attitudes. Nonetheless, not much is known about the factors that influence teachers’ attitudes toward teaching integrated STEM. Therefore this paper uses a survey method to get insight into the relationship between three groups of variables and teachers’ attitudes toward teaching integrated STEM: teacher background characteristics, personal attitudes and school context variables. The results of the multiple regression analyses reveal three variables that are positively linked with teachers’ attitudes: professional development, personal relevance of science and social context. Moreover two variables show a negative correlation: having more than 20 years of teaching experience and experience in mathematics. The results of this study provide valuable information about factors related to teachers’ attitudes toward teaching integrated STEM. Moreover, these results can be deployed by school administrators to guide them when implementing integrated STEM education in their school.     

Piloting technological understanding and reasoning in Icelandic schools

A pilot research was undertaken in Icelandic schools during the 2013–2014 school year, in order to explore students’ technological understanding and reasoning at the ages of 11 and 13. The survey included a questionnaire regarding mechanical movement, power and thermodynamics, while the project considered the congruity between students’ undertakings within Design and Craft education in the national curricula and their ability to understand technology. This article examines the literature and considers the value of technology lessons within Icelandic Design and Craft education, in terms of students’ technological competence. Data was collected using a questionnaire distributed to three elementary schools and is highlighted with the researchers’ reviews of the national curricula. Findings were discussed and conclusions drawn and the results highlighted a general lack of understanding in technology, within the context of students’ daily lives. In addition, there were differences between boys and girls.     

Effects of web-based versus classroom-based STEM learning environments on the development of collaborative problem-solving skills in junior high school students

Collaborative problem-solving skills are one of the key competencies required in the twenty-first century. In this study, researchers attempted to compare the effectiveness of web-based collaborative problem-solving systems (wCPSS) and classroom-based collaborative hands-on learning activities (cCHLA) in the development of collaborative problem-solving skills in junior high school students who were learning science, technology, engineering, and mathematics (STEM)-related subjects. A quasi-experimental, nonequivalent pretest–posttest control group design was employed, and 241 junior high school students were invited to participate in the study. According to the results, a wCPSS-supported environment with teacher guidance was found to be more effective than either a wCPSS-supported environment without teacher guidance or a cCHLA-facilitated environment in developing students’ collaborative problem-solving skills in STEM fields. The study suggested that a web-based collaborative problem-solving system with teacher guidance can be used in developing junior high students’ collaborative problem-solving skills in STEM education.     

Nanotechnology awareness, opinions and risk perceptions among middle school students

The present study investigates awareness, factual knowledge, opinions, and risk perceptions of students from Turkish middle schools with regard to nanotechnology in a very general sense. The study was carried out among 1,396 middle school 6th, 7th, and 8th grade students. The students’ perceptions of and opinions about nanotechnology were elicited through a questionnaire developed by the authors. Students have some awareness of nanotechnology and most students had positive emotions and opinions about it. Students’ risk perceptions of nanotechnology and the influence of the demographic and affective domain, achievement in science courses, and science motivation on these perceptions were also investigated. The results show that, for gender, no significant difference was observed. However, for some of the demographic and affective domain factors, and achievement in science courses, significant differences were found.     

Attitudes towards science, technology, engineering and mathematics (STEM) in a project-based learning (PjBL) environment

Many scholars claimed the integration of science, technology, engineering and mathematics (STEM) education is beneficial to the national economy and teachers and institutes have been working to develop integrated education programs. This study examined a project-based learning (PjBL) activity that integrated STEM using survey and interview methods. The participants were 30 freshmen with engineering related backgrounds from five institutes of technology in Taiwan. Questionnaires and semi-structured interviews were used to examine student attitudes towards STEM before and after the PjBL activity. The results of the survey showed that students’ attitudes to the subject of engineering changed significantly. Most of the students recognized the importance of STEM in the science and engineering disciplines; they mentioned in interview that the possession of professional science knowledge is useful to their future career and that technology may improve our lives and society, making the world a more convenient and efficient place. In conclusion, combining PjBL with STEM can increase effectiveness, generate meaningful learning and influence student attitudes in future career pursuit. Students are positive towards combining PjBL with STEM.     

Modeling the relation between students’ implicit beliefs about their abilities and their educational STEM choices

Despite the large body of research on students’ educational and career choices in the field of technology, design, and science, we still lack a clear understanding of how to stimulate more students to opt for a study path or career within the STEM fields (Science, Technology, Engineering, Mathematics). In this article, we outline a new theoretical framework to describe how students’ implicit belief about the malleability of their intelligence can be an important precursor of their STEM educational and career choice behavior. Based on the different bodies of literature about STEM choices and about students’ implicit beliefs about their abilities, we present three hypothetical pathways, in the form of testable models, that describe potential relations between the implicit theories that students may hold regarding the malleability of their STEM ability and students’ intentions to pursue a STEM career. Each pathway outlines a specific mediating factor influencing this relation: (a) self-efficacy beliefs, (b) stereotypical thinking, and (c) motivational beliefs. These pathways provide more insight into the underlying mechanisms that may affect STEM choice behavior. In our view, such a theoretical underpinning is a necessary prerequisite for further scientific investigation into the potential relations between students’ implicit beliefs about their potential development, relevant psychological variables, and STEM choice behavior. Furthermore, we believe it provides a theoretical foundation for practical interventions that aim to stimulate STEM choice behavior.     

Assessing changes in teachers’ attitudes toward interdisciplinary STEM teaching

Integrating engineering and technology concepts into K-12 science and math curricula through engineering design project-based learning has been found to increase students’ interest in science, technology, engineering, and mathematics (STEM), however preparing teachers to shift to interdisciplinary teaching remains a significant challenge. Primarily teachers need to develop both skills and attitudes toward interdisciplinary teaching. In doing so, professional development (PD) is considered a key component in helping teachers through this transformation process. In an educational environment of accountability, measuring the effects of PD programs on teacher behaviors and capacity is essential but often elusive. The current study describes the change in attitudes to interdisciplinary teaching of 29 self-selected middle and high school teachers who participated a PD workshop and in delivering a 12–15 week interdisciplinary teaching and design problem unit that spanned multiple STEM subjects. This quasi-experimental pilot study implemented a single group pretest–posttest design using survey methods to collect data from the participants at two intervals; at the time of the PD workshop and at the completion of the teaching unit that emphasized a long-term engineering design problem. The goals of this research are to (1) assess the changes in attitudes to interdisciplinary teaching, attitudes to teamwork, teaching satisfaction, and resistance to change, (2) explore relationships among these changes, (3) and describe the variation in these changes across teachers’ gender, school level, discipline taught, and education level.     

Monopolising the STEM agenda in second-level schools: exploring power relations and subject subcultures

The ubiquitous and often pervasive expansion of the science, technology, engineering and mathematics (STEM) agenda across global education systems has largely gone uncontested. Strategic efforts to build on perceived natural subject synergies across the separate STEM disciplines are promoted as central to supporting the growth of economies through the development of human capital and by ensuring the supply of suitably trained individuals for vocational roles in these areas. However, these efforts are predicated on the assumption that such perceived natural subject synergies can easily support pedagogical complimentary and in so doing, often fail to acknowledge the social histories of the subjects involved. In this paper the authors examine the divergence in treatment of STEM subjects within the Irish second-level context through the lenses of subject hierarchies and social class. The cultural capital associated with studying each of the respective STEM subjects in school is considered and the objectives of the STEM agenda are problematised.     

Learning to think spatially in an undergraduate interdisciplinary computational design context: a case study

Spatial thinking skills are vital for success in everyday living and work, not to mention the centrality of spatial reasoning in scientific discoveries, design-based disciplines, medicine, geosciences and mathematics to name a few. This case study describes a course in spatial thinking and communicating designed and delivered by an interdisciplinary team over a three-year period to first-year university students. Four major elements provide a framework for the sequencing of instruction and acquisition of 2D and 3D spatial thinking and reasoning skills in a computational design context. We describe the process of introducing students to computational design environments beginning with a fun and familiar tool in preparation for a more complex, industry-standard system (SolidWorks). A design project provides diverse student teams an opportunity to integrate and apply foundational spatial concepts and skills including sketching, 2D and 3D representations, as well as digital and physical modeling. Samples of student work illustrate the scaffolding necessary for students to successfully draw upon the spatial thinking and communication skills required to complete their team projects beginning with applying sketching techniques; modeling individual 3D parts; creating digital assemblies; and finally building the equivalent 3D physical model. Key instructional principles provide a framework for the analysis of what worked and what didn’t in relation to spatial skills development in students. The lessons learned are identified along with potential future directions for teaching and learning scholarship in spatial thinking development within a computational design context.     

Design and technology productions among middle school students: an Indian experience

The focus of this paper is students’ design productions as they engaged in designing and making a windmill model to lift a given weight. This work is part of a project on the development of design and technology (D&;T) education units and its trials among Indian middle school students (Grade 6, age 11–14 years) in different socio-cultural settings. Since D&;T is not a part of the Indian school curriculum, the students had no earlier experience of design. Our trials included an exploratory phase followed by groups of students producing technical drawings and a plan for the making action (procedural map) before engaging in making the windmill model. The paper presents findings from a qualitative analysis of urban and rural students’ pencil and paper productions, complemented by observations from video recordings of the collaborative engagement of these naïve designers. Students used graphical symbols, analogical, spatial and functional reasoning in their design activities. Choice of materials and tools, the nature of exploratory sketches, variety in design and attentions to issues of stability showed differences between the urban and rural groups. Some potential implications of D&;T units for classroom learning have also been discussed.     

Why do students present different design objectives in engineering design projects?

Engineering design practice has been recognized as an effective approach to engage students in STEM learning. However, we noticed that students who possessed strong STEM knowledge did not necessarily perform well on their design projects. Thus, this study sought to explore factors that shaped students’ design objectives and means. A design-based research was adopted using a single group teaching experiment, in which students’ performance in relation to conceptual knowledge, engineering design practice, and their STEM attitudes were assessed in different design complexity groups. Based on the findings of this study, we concluded that students’ interest and metacognitive skills might be the key factors affecting their motivation during the engineering design process. Their abilities in predictive analysis and testing/revising were core elements affecting their design thinking. Our work provides preliminary evidence on how students form and present different design purposes and objectives in an engineering design project.     

Australian enrolment trends in technology and engineering: putting the T and E back into school STEM

There has been much political and educational focus on Science, Technology, Engineering and Mathematics (STEM) in Australian schools in recent years and while there has been significant research examining science and mathematics enrolments in senior high school, little is known about the corresponding trends in Technologies and engineering. Understanding these subjects is essential for educators and policy-makers alike if Australians are to embrace the challenges of an innovation economy. We have collected raw enrolment data from each of the Australian state and territory education departments from 1992 to 2014 and analysed this across five Technology and Engineering subject areas. We also consider some of the relationships between these subject areas and other areas of the STEM equation. The results of these analyses are discussed in terms of absolute enrolments, participation rates and sex balance. We have found that the total number of students in Year 12 increased year on year and that this growth is echoed, to a lesser extent, in the participation rates for design technology, food technology and engineering. Digital Technologies however, grew rapidly until 2000, after which time it has been in steady decline. We identify that while the trends mostly show growth, there is a concerning male bias to many of these subject areas. We suggest that the broadening of the upper high school curriculum, confusion surrounding vocational training enrolments, and gamesmanship of the university entrance system, may be contributing to the limited growth observed. Finally, we identify a number of important areas for further research in this key learning area.
