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 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.     

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 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.     

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.     

The use of design practice to teach mathematics and science

Relatively low participation in the hard sciences (mathematics, science, engineering and technology) has become a concern with respect to the capacity of Australia to meet critical infrastructure projects. This problem has its roots in poor student attitudes towards and perceptions about the study of prerequisite subjects including mathematics and science. Perception formation commences early in students’ education where students have claimed that mathematics was not intrinsically useful and was difficult to understand. With this mind, an intervention was planned and implemented in which technology and design practice was used to integrate the study of mathematics so students could produce and explain a useful artefact. The integrated design project included a focus upon instructional and regulatory discourse. Useful integration tools were developed that facilitated positive cognitive discourses such that students demonstrated a functional understanding of mathematical concepts, reported a broader and more applied understanding of the nature of mathematics and a belief that integration had helped them to make more sense of mathematics.     

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.     

Occupational matching into science and technology jobs—gender‐based differences

Policy to remedy gender disparities in science, technology, engineering and mathematics (STEM) occupations in the US have typically focused on educational achievements. However, an analysis of mid‐career STEM workers reveals that significant gender‐based differences exist in the role that education and other factors play in occupational matching.     

Understanding attitude measurement: exploring meaning and use of the PATT short questionnaire

The pupils’ attitudes toward technology survey (PATT) has been used for 30 years and is still used by researchers. Since it was first developed, the validity of the questionnaire constructs has primarily been discussed from a statistical point of view, while few researchers have discussed the type of attitudes and interest that the questionnaire measures. The purpose of this study is to increase the knowledge about student interpretations and the meaning of their answers in the recently developed PATT short questionnaire (PATT-SQ). To research this, a mixed methods approach was used, where the qualitative data from six interviewees (students aged 14) help to explain and interpret the quantitative data from 173 respondents (students aged 12–15). The interviewed students completed a Swedish version of the PATT-SQ 3 weeks prior a semistructured interview. The results from this study imply that the PATT-SQ survey can be used mostly as it is, but this study also shows that there are some categories that require some caution when being analyzed and discussed. For example, the gender category cannot be used as intended since it does not measure what it is supposed to and it might be gender-biased. The interest category can advantageously be reduced to four items to focus on school technology, which will indicate how deep a student’s well-developed individual interest is. And the career category seems to only detect students’ who urge a career in technology, while the other students lack knowledge about what that career might be and therefore they are not interested in such a career.     

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.     

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.     

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.     

Student response to an Internet-mediated industrial design studio course

The purpose of this study is to investigate student attitudes towards and perceptions of using the Internet and information technology to mediate a design studio course and to propose guidelines and suggestions for developing Internet-mediated design studio courses. Two classes of third-year undergraduate industrial design students in two collaborating universities in Taiwan—Chang Gung University and National Yunlin University of Science and Technology—participated in an experimental design studio course mediated with an online design learning environment. Surveys and focus group interviews were conducted at the end of the course to record students’ attitudes and perceptions. The students thought that the approach used had a positive influence on design teaching and learning and expressed acceptance of using the Internet to support design education. Finally, suggestions were proposed to help design educators in adopting, modifying, and developing systems for using the Internet to mediate design studio courses.     

STEM education in the twenty-first century: learning at work—an exploration of design and technology teacher perceptions and practices

Teachers’ knowledge of STEM education, their understanding, and pedagogical application of that knowledge is intrinsically linked to the subsequent effectiveness of STEM delivery within their own practice; where a teacher’s knowledge and understanding is deficient, the potential for pupil learning is ineffective and limited. Set within the context of secondary age phase education in England and Wales (11–16 years old), this paper explores how teachers working within the field of design and technology education acquire new knowledge in STEM; how understanding is developed and subsequently embedded within their practice to support the creation of a diverse STEM-literate society. The purpose being to determine mechanisms by which knowledge acquisition occurs, to reconnoitre potential implications for education and learning at work, including consideration of the role which new technologies play in the development of STEM knowledge within and across contributory STEM subject disciplines. Underpinned by an interpretivist ontology, work presented here builds upon the premise that design and technology is an interdisciplinary educational construct and not viewed as being of equal status to other STEM disciplines including maths and science. Drawing upon the philosophical field of symbolic interactionism and constructivist grounded theory, work embraces an abductive methodology where participants are encouraged to relate design and technology within the context of STEM education. Emergent findings are discussed in relation to their potential to support teachers’ educational development for the advancement of STEM literacy, and help secure design and technology’s place as a subject of value within a twenty-first Century curriculum.     

An analysis of the impact of student–scientist interaction in a technology design activity,using the expectancy-value model of achievement related choice

Many education initiatives in science and technology education aim to create enthusiasm among young people to pursue a career in Science, Technology, Engineering, and Mathematics (STEM). Research suggests that personal interaction between secondary school students and scientists could be a success factor, but there is a need for more in-depth research on the actual effects of science education initiatives. This paper describes an in-depth, qualitative assessment of a technology design activity, using as a theoretical framework the expectancy-value model of academic choice Eccles and Wigfield (Annu Rev Psychol 53:109–132, 2002). A core element in the studied education initiative is the interaction between secondary school students and scientists. Semi-structured interviews were conducted with participating students and analysed qualitatively to disentangle the factors in their motivation to participate in this initiative and their experiences and memories gathered during participation. Last, this paper reflects on the use of the expectancy-value model for in-depth assessments of science education initiatives. Results show that interest-enjoyment values and attainment values are most important in the students’ motivation to participate in the studied activity. These values are connected to educational principles of authentic practice, and of providing meaningful contexts for scientific concepts. Furthermore, results show that the interaction between students and scientists is not automatically a success factor. Disappointment in this interaction, can cast a shadow on students’ whole experience. This leads us to propose to include an additional factor in the expectancy-value model of achievement related choice: educational environment, including ‘personal interaction’ as an element. Adding this factor would—in our opinion—create an even better framework for in-depth assessment of science education initiatives.     

Examining design cognition coding schemes for P-12 engineering/technology education

Cultivating students’ design abilities can be highly beneficial for the learning of science, technology, engineering, and mathematics (STEM) concepts, and development of higher-order thinking capabilities (National Academy of Engineering and National Research Council in STEM integration in k-12 education: status, prospects, and an agenda for research, The National Academies Press, Washington, 2014). Therefore, examining students’ strategies, how they distribute their cognitive effort, and confront STEM concepts during design experiences, can help educators identify effective and developmentally appropriate methods for teaching and scaffolding design activities for students (National Research Council in standards for k-12 engineering education? The National Academies Press, Washington, 2010). Yet, educational researchers have only recently begun examining students’ engineering design cognition at the P-12 level, despite reports such as Standards for K-12 Engineering Education? (National Research Council 2010) designating this area of research as lackluster. Of the recent studies that have investigated engineering design cognition at the P-12 level, the primary method of investigation has been verbal protocol analysis using a think-aloud method (Grubbs in further characterization of high school pre- and non-engineering students’ cognitive activity during engineering design, 2016). This methodology captures participants’ verbalization of their thought process as they solve a design challenge. Analysis is typically conducted by applying a pre-determined coding scheme, or one that emerges, to determine the distribution of a group’s or an individual’s cognition. Consequently, researchers have employed a variety of coding schemes to examine and describe students’ design cognition. Given the steady increase of explorations into connections between P-12 engineering design cognition and development of student cognitive competencies, it becomes increasingly important to understand and choose the most appropriate coding schemes available, as each has its own intent and characteristics. Therefore, this article presents an examination of recent P-12 design cognition coding schemes with the purpose of providing a background for selecting and applying a scheme for a specific outcome, which can better enable the synthesis and comparison of findings across studies. Ultimately, the aim is to aid others in choosing an appropriate coding scheme, with cognizance of research analysis intent and characteristics of research design, while improving the intentional scaffolding and support of design challenges.     

The ethical implications of collecting data in educational settings: discussion on the technology and engineering attitude scale (TEAS) and its psychometric validation for assessing a pre-engineering design program

International Journal of Technology and Design Education - K-12 Engineering Education has placed a lot of attention on students’ attitudes or predispositions towards science and technology....
