Why 3D Print? The 21st-Century Skills Students Develop While Engaging in 3D Printing Projects

The emergence of 3D printing has raised hopes and concerns about how it can be used effectively as an educational technology in school classrooms. This paper presents the results of a survey asking teachers from multiple grade levels and subject fields about the impact of 3D projects on student learning. Teachers were asked about the kinds of 3D projects they were doing with students and what skills or knowledge students were developing by participating in those projects. Participants reported that their students developed a number of skills while working on 3D printing projects, including 3D modeling, creativity, technology literacy, problem-solving, self-directed learning, critical thinking, and perseverance. Parallels between teacher-identified skills and widely cited lists of 21^st-century skills suggest that 3D projects are a promising approach to preparing students for life and work in a digital age.     

Teachers' learning while constructing technology‐based instructional resources

Grounded in a constructionist paradigm, this study examined elementary school teachers' learning while creating technology‐rich instructional materials. Sixteen teachers at an elementary school were interviewed about their experience. Using the components of Technological Pedagogical and Content Knowledge as an analytical framework, inductive qualitative analysis indicated that these professional learning activities led to teachers' growth primarily in technological knowledge, technological pedagogical knowledge and content knowledge. These findings as well as implications for designing professional learning activities for teachers are also shared.     

Enhancing Teachers' Technological Knowledge and Assessment Practices to Enhance Student Learning in Technology: A Two-year Classroom Study

This paper reports on a two-year classroom investigation of primary school (Years 1–8) technology education. The first year of the project explored emerging classroom practices in technology. In the second year intervention strategies were developed to enhance teaching, learning and assessment practices. Findings from the first year revealed that assessment was often seen in terms of social and managerial aspects, such as teamwork, turn taking and co-operative skills, rather than procedural and conceptual technological aspects. Existing formative interactions with students distorted the learning away from the procedural and conceptual aspects of the subject. The second year explored the development of teachers' technological knowledge in order to enhance formative assessment practices in technology, to inform classroom practice in technology, and to enhance student learning. Intervention strategies were designed to enhance the development of procedural, conceptual, societal and technical aspects of technology for teachers and students. The results from this intervention were very positive. This paper highlights the importance of developing teacher expertise pertaining to broad concepts of technology, detailed concepts in different technological areas and general pedagogical knowledge. The findings from this research therefore have implications for thinking about teaching, learning and assessment in technology.     

Teacher use of evidence to customize inquiry science instruction

This study investigated how professional development featuring evidence‐based customization of technology‐enhanced curriculum projects can improve inquiry science teaching and student knowledge integration in earth science. Participants included three middle school sixth‐grade teachers and their classes of students (N = 787) for three consecutive years. Teachers used evidence from their student work to revise the curriculum projects and rethink their teaching strategies. Data were collected through teacher interviews, written reflections, classroom observations, curriculum artifacts, and student assessments. Results suggest that the detailed information about the learning activities of students provided by the assessments embedded in the online curriculum motivated curricular and pedagogical customizations that resulted in both teacher and student learning. Customizations initiated by teachers included revisions of embedded questions, additions of hands‐on investigations, and modifications of teaching strategies. Student performance improved across the three cohorts of students with each year of instructional customization. Coupling evidence from student work with revisions of curriculum and instruction has promise for strengthening professional development and improving science learning. © 2010 Wiley Periodicals, Inc.

Motivating Project-Based Learning: Sustaining the Doing,Supporting the Learning

Project-based learning is a comprehensive approach to classroom teaching and learning that is designed to engage students in investigation of authentic problems. In this article, we present an argument for why projects have the potential to help people learn; indicate factors in project design that affect motivation and thought; examine difficulties that students and teachers may encounter with projects; and describe how technology can support students and teachers as they work on projects, so that motivation and thought are sustained.     

Effects of active‐learning experiences on achievement,attitudes, and behaviors in high school biology

Active‐learning labs for two topics in high school biology were developed through the collaboration of high school teachers and university faculty and staff and were administered to 408 high school students in six classrooms. The content of instruction and testing was guided by State of Texas science objectives. Detailed teacher records describing daily classroom activities were used to operationalize two types of instruction: active learning, which used the labs; and traditional, which used the teaching resources ordinarily available to the teacher. Teacher records indicated that they used less independent work and fewer worksheets, and more collaborative and lab‐based activities, with active‐learning labs compared to traditional instruction. In‐class test data show that students gained significantly more content knowledge and knowledge of process skills using the labs compared to traditional instruction. Questionnaire data revealed that students perceived greater learning gains after completing the labs compared to covering the same content through traditional methods. An independent questionnaire administered to a larger sample of teachers who used the lab‐based curriculum indicated that they perceived changing their behaviors as intended by the student‐centered principles of the labs. The major implication of this study is that active‐learning–based laboratory units designed and developed collaboratively by high school teachers and university faculty, and then used by high school teachers in their classrooms, can lead to increased use of student‐centered instructional practices as well as enhanced content knowledge and process learning for students. © 2007 Wiley Periodicals, Inc.

To design or to integrate? Instructional design versus technology integration in developing learning interventions

Instructional Design Knowledge (IDK) can inform technology integration decisions and Technology Pedagogy and Content Knowledge (TPACK) can help instructional design processes. As a means to understand how teachers may draw from their TPACK and IDK as they design instructions and develop technology-enhanced learning activities, we examined the final projects of two groups of teachers enrolled in graduate-level instructional design and technology courses. By using both content and social network analysis methods, we identified the IDK and TPACK components exemplified in teachers’ projects. While the content analysis revealed differences between the two groups, some findings were common across the courses such as teachers minimally connecting technology to their content areas, exhibiting limited knowledge on learning needs, and having difficulties in engaging in design thinking processes. Furthermore, the social network analysis identified various communities of the knowledge components, highlighting when teachers tended to use their IDK and TPACK as they planned technology-enhanced learning activities and were engaged in instructional design respectively.

     

An analysis of student teachers' understanding of integration of science and technology activities

Abstract

The research reported on in this article was conducted to determine if student teachers enrolled in a Bachelor of Education programme at a South African University are able to integrate science and technology in their teaching. The participants were a cohort of students registered for a course aimed at preparing them to teach grades 4 to 6 in the primary school. The theoretical framework applied in the study is Rogan's Zone of feasible Innovation (ZFI) which uses the analogy that curriculum strategies are good when they proceed just ahead of current practice. Students' understanding of integration of two learning areas was compared to their knowledge base. The findings suggest that students who have very little knowledge of science and/or technology have difficulty in understanding what the scientific and technological processes mean and without this understanding are unable to integrate science and technology effectively in their teaching. It is recommended that the B.Ed programme at this university focuses more on providing opportunities for students to acquire sound knowledge of the two disciplines before attempting any form of integration.     

Technological,pedagogical and content knowledge in one-to-one classroom: teachers developing “digital wisdom”

One-to-one (1X1) laptop initiatives become prevalent in schools aiming to enhance active learning and assist students in developing twenty-first-century skills. This paper reports a qualitative investigation of all 7th graders and their 15 teachers in a junior high-school in Northern Israel gradually implementing 1X1 model. The research was conducted during a second year of 1X1 implementation at the school level, which was a first year of teaching and learning with laptops for all study participants. The study triangulates non-participant lessons’ observations and semi-structured interviews with 15 teachers. The data were collected twice: at the beginning and toward the end of the 2011–2012 academic year – in total, 30 observations and 30 interviews were conducted. The results were examined through phenomenological research techniques and discussed in terms of the technological, pedagogical and content knowledge (TPACK) and “digital wisdom” approaches. The teachers showed significant increase of technological knowledge. However, only moderate connections between technology and pedagogy as well as between technology and content were found. Some of the teachers functioned as moderators, scaffolding students and supporting their individual or collaborative learning. However, many teachers struggled with effective management of 1X1 classroom. Neither conjunction of teacher TPACK nor facilitation of student digital skills was observed. The paper suggests an overlap of the TPACK framework and the digital wisdom approach and provides implications for curriculum developers and educational policy-makers.     

Conditions for Successful Use of Technology in Social Studies Classrooms

The purpose of the authors in this review is to examine how teacher-related, context-related, and project-related conditions interact in successful cases of technology integration projects in social studies classrooms. A close examination of different dimensions of these conditions in the implementation of 33 successful cases of technology-assisted projects showed the importance of strong pedagogy-technology alignment. This is in line with the emphasis given to the centrality of technological pedagogical content knowledge by the practitioner in the technological pedagogical content knowledge framework. Other conditions found to be important for the success of the projects were focus and clarity of targeted learning outcomes and the supportive role of teacher educators when collaborating with teachers in designing and implementing the projects. The implication of these findings for school research and practice and teacher education is discussed.     

Tracking Professional Development of Novice Teachers when Integrating Technology in Teaching Mathematics

This research traced changes in choices of technological tools and attitudes toward technology use among novice mathematics teachers at three stages of their professional development: as pre-service teachers, a year later, and in their work as novice teachers. At each stage, the participants were required to evaluate the benefits of technology use in their learning/teaching.

We found that the novice mathematics teachers used a variety of technological tools, while as students they preferred to use digital presentations or dynamic software. Moreover, the novice teachers used two additional tools: the school platform and the WhatsApp instant messaging application. The novice teachers placed significantly higher value on the benefits of using technology in teaching in terms of improvement in learning, enhancement of pupils' motivation and increased effectiveness of the lesson. These results indicated that only as practical teachers were the participants able to see the benefits of technology.     

基于学习共同体的中小学生学习心理机制及有效教学策略

学习共同体的学习方式有别于传统的教师主讲式的课堂授课形式。学习共同体特别强调"师-生"之间,"生-生"之间缔结一个相互联系、相互制约、彼此促进的共同体来完成学生的学习活动。基于学习共同体的中小学生学习心理机制是一种主动建构、信息加工的过程,即:"1.输入信息、注意保持、认知观念;2.加工信息、内化知识、建构系统;3.改组经验、解决问题、生成能力"。学习共同体旨在教师引导下,让学生通过自主探究、小组讨论、合作分享、获得知识、生成能力。教师实施有效的教学策略,充分发挥学习共同体的功能,会促进培养中小学生的核心素养,提升学生分析问题解决问题能力。     

Explaining Student Achievement: the Influence of Teachers’ Pedagogical Content Knowledge in Statistics

Statistics is an increasingly important component of the mathematics curriculum. StatSmart was a project intended to influence middle-years students’ learning outcomes in statistics through the provision of appropriate professional learning opportunities and technology to teachers. Participating students in grade 5/6 to grade 9 undertook three tests, a pre-test, a post-test and a longitudinal retention test over a period of 2 years. Their teachers completed a survey that included items measuring pedagogical content knowledge (PCK) for teaching statistics. Despite the development of valid instruments to measure both student and teacher content knowledge and teachers’ PCK, linking teachers’ knowledge directly to students’ learning outcomes has proved elusive. Multilevel modelling of results from 789 students for whom there were 3 completed tests and measures from their teachers indicated that students’ outcomes were influenced positively by their initial teacher’s PCK. Extended participation of teachers in the project also appeared to reduce negative effects of changing teachers.     

How teachers learn: the roles of formal,informal, and independent learning

A qualitative study of math and science teachers at two middle schools identifies how their system for learning to integrate technology into their teaching goes beyond what school leaders typically consider when planning for teachers’ learning. In addition to (a) the district-initiated, or formal, system of professional development (PD) and professional learning communities (PLCs), it includes (b) teacher-initiated, or informal, learning with colleagues as well as (c) teachers’ independent learning activities. Analysis of why and how they form their system highlights how by only supporting the formal PD activities and PLCs, the district not only loses the valuable collective knowledge of the districts’ teachers derived from their informal and independent learning activities, but also diminishes the learning teachers derive from the formal PD activities since informal collaborations and independent work after formal PD activities often helps to bring the learning from the training room to the classroom. We present teachers’ insights and then discuss implications for the design of a holistic approach to facilitate teachers’ formal, informal, and independent learning that is tied together and supported by technology. While research on formal, informal and independent teacher learning exists, with technology frequently mentioned as a potential support for each of these three modes, these approaches have not been considered together as interdependent parts of the same holistic system for teacher learning nor has the way technology might knit these modes of teacher learning together been imagined as a part of that system.     

Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.     

Preservice teacher education

Conclusion Responsible educators find the need for continual renewal. The rapid advance of technology requires teachers learn new strategies and techniques for the productive use of these tools. The projects described above provided preservice faculty, students, and inservice educators with opportunities to learn about new technologies and to explore innovative uses of the technology. Opportunities to utilize distance education systems, such as the Iowa Communications Network, are numerous throughout the entire teacher preparation process. Iowa teacher educators have the opportunity to prepare their students to be capable classroom teachers who have the knowledge and skills to facilitate learning in an array of educational environments.     

Students’ Perceptions of Their Science Teachers’ Pedagogical Content Knowledge

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK.     

Incorporating Concept Mapping in Project-Based Learning: Lessons from Watershed Investigations

The concept map tool set forth by Novak and colleagues is underutilized in education. A meta-analysis has encouraged teachers to make extensive use of concept mapping, and researchers have advocated computer-based concept mapping applications that exploit hyperlink technology. Through an NSF sponsored geosciences education grant, middle and secondary science teachers participated in professional development to apply computer-based concept mapping in project-based learning (PBL) units that investigated local watersheds. Participants attended a summer institute, engaged in a summer through spring online learning academy, and presented PBL units at a subsequent fall science teachers’ convention. The majority of 17 teachers who attended the summer institute had previously used the concept mapping strategy with students and rated it highly. Of the 12 teachers who continued beyond summer, applications of concept mapping ranged from collaborative planning of PBL projects to building students’ vocabulary to students producing maps related to the PBL driving question. Barriers to the adoption and use of concept mapping included technology access at the schools, lack of time for teachers to advance their technology skills, lack of student motivation to choose to learn, and student difficulty with linking terms. In addition to mitigating the aforementioned barriers, projects targeting teachers’ use of technology tools may enhance adoption by recruiting teachers as partners from schools as well as a small number that already are proficient in the targeted technology and emphasizing the utility of the concept map as a planning tool.
