Integrating mathematics,science, and technology: effects on students

Few studies have examined the student learning effects of integrating science with mathematics and technology. We compared a school that integrated mathematics, science and technology in grade 9 to a school in the same district that taught the three courses separately. The distinguishing feature of the integrating school was the reorganization of instruction in the three subjects to prepare students for seven group projects (involving a total of 25 h) that required the application of knowledge and skill that were shared by the three subjects, as well as learning outcomes that were unique to each. The study detected benefits for students in the integrated setting in terms of their ability to apply shared learning outcomes, student motivation, ability to work together and attitudes to appraisal of group work. Female students in the integrated school had a better understanding of selected science learning outcomes. Attitudes toward mid‐term exams were higher in the control school.

     

Inquiry-based science teaching competence of primary school teachers: A Delphi study

Earlier, extracted inquiry-based science teaching competency elements and domains from the international literature were compared to the United States' National Science Teaching Standards. The present Delphi study aimed to validate the findings for the Netherlands, where such standards are lacking. Experts (N = 33) were asked about the importance of 23 identified competencies. They confirmed the importance; proposed to add one competency and to differentiate between novice and experienced teachers. They suggested that teachers be provided with opportunities to integrate competence development regarding science knowledge, attitude and teaching skills throughout their career.     

Proof schemes and learning strategies of above-average mathematics students

What patterns can be observed among the mathematical arguments above-average students find convincing and the strategies these students use to learn new mathematical concepts? To investigate this question, we gave task-based interviews to eleven female students who had performed well in their college-level mathematics courses, but who differed in the number of proof-oriented courses each had taken. One interview was designed to elicit expressions of what students find convincing. These expressions were categorized according to the proof schemes defined by Harel and Sowder (1998). A second interview was designed to elicit expressions of what strategies students use to learn a mathematical concept from its definition, and these expressions were classified according to the learning strategies described by Dahlberg and Housman (1997). A qualitative analysis of the data uncovered the existence of a variety of phenomena, including the following: All of the students successfully generated examples when asked to do so, but they differed in whether they generated examples without prompting and whether they successfully generated examples when it was necessary to disprove conjectures. All but one of the students exhibited two or more proof schemes, with one student exhibiting four different proof schemes. The students who were most convinced by external factors were unsuccessful in generating examples, using examples, and reformulating concepts. The only student who found an examples-based argument convincing generated examples far more than the other students. The students who wrote and were convinced by deductive arguments were successful in reformulating concepts and using examples, and they were the same set of students who did not generate examples spontaneously but did successfully generate examples when asked to do so or when it was necessary to disprove a conjecture.     

Using technology in assessing integrated science and mathematics learning

Drawing from current models, research, and science and mathematics education reform documents, this article first defines and/or delimits three broad domains of education: integrated school science and mathematics, assessment, and technology. Based upon this three-tiered discussion, a list of characteristics is then distilled to guide in the development of assessment for integrated school science and mathematics using technology. Two integrated school science and mathematics activities are provided to illustrate the alignment of instruction and assessment and the systematic integration of technology into both.The writing of this paper was supported by The National Center for Science Teaching and Learning under grant R117Q00062 from the Office of Educational Research and Improvement, U.S. Department of Education.

Digital curation for promoting personalized learning: A study of secondary-school science students’ learning experiences

Abstract

The article presents a research study that examined the ways in which digital curation promotes personalized learning, as well as the students’ experiences of this learning process. The study was conducted in the context of K-12 education. Participants spent three months on a project that included curating a personalized digital collection. The study was conducted using a phenomenological qualitative approach for the collection and processing of data. Findings demonstrate that digital curation provides a productive learning activity that supports significant personalized, emotional, and cognitive learning experiences, enabling the curator to construct a personal subject ontology.     

Student group presentations: a learning instrument in undergraduate mathematics for engineering students

In this study we created an environment for peer learning, where students teach students by making oral presentations in groups about solving mathematical problems and explaining the theoretical background in mathematics, during the first year of an undergraduate engineering programme at the Norrköping campus of the Linköping University. In order to strengthen the students’ understanding and perception of central mathematical concepts, the study was designed to take the students through five different learning experiences, preparing the presentation, presenting the mathematics, listening to others presenting, discussion by all students after the presentation and feedback by the teacher to the small group of students separate from the other students. We study how oral presentations work as a learning and assessment method. The study consisted of three stages. After a first run of the presentations as a learning instrument, three guidebooks with recommendations for students and teachers were developed in order to assist students as well as teachers about their role in this learning environment. Students’ and teachers’ views on the student presentations as learning instrument were surveyed before and after the intervention. In stage three, students were interviewed individually to ascertain the relevant success of the different learning experiences.

Messy learning: Preservice teachers’ lesson-study conversations about mathematics and students

Research about lesson study and other forms of collaborative, practice-based professional development has tended to focus on identifying structures that support teacher learning. This study builds on this work by examining preservice elementary teachers’ efforts to conduct lesson studies in mathematics. Analysis showed that the structures of the lesson study project supported some groups in developing mathematical and equity lenses for looking at teaching; however, the use of these lenses simultaneously led to productive and problematic learning. This finding suggests that future research focus on challenges present in collaborative, practice-based work even when productive structures are in place.     

Inquiry-based science instruction and performance literacy for students who are deaf or hard of hearing

Deaf and hard of hearing students, who cannot successfully access and utilize information in print, experience various difficulties in conventional science instruction, which heavily relies on lectures and textbooks. The purpose of the present review is threefold. First, an overview of inquiry-based science instruction reform, including the so-ciohistorical forces behind the movement, is presented. Then, the author examines the empirical research on science education for students who are deaf or hard of hearing from the 1970s to the present and identifies and rates inquiry-based practice. After discussing the difficulty of using science texts with deaf and hard of hearing students, the author introduces a conceptual framework that integrates inquiry-based instruction and the construct of performance literacy. She suggests that this integration should enable students who are deaf or hard of hearing to access the general education curriculum.

A new look in representations for mathematics and science learning

Representations such as formal notations and diagrams routinely figure in students' learning of mathematics and science. However, in light of the extensive research on students' misunderstanding in these subject matters, it is reasonable to ask whether other kinds of representations might help students to reach better understandings. Indeed, a number of educators have developed innovative representations, typically on computers, that supposedly foster understanding through suggestive visual analogies and microworlds to manipulate. Evaluative research on these new look representations as we call them suggests that they indeed can help students to understand.In this review, we focus on exactlyhow these representations aid understanding. We propose that they do so by facilitating the learner's construction of explanations, justifications, predictions, and the like. These constructions require search in problem spaces, in the sense of Newell and Simon (1972). The representations in question reduce the cognitive load of such searches, clarify the structure of the problem spaces that need to be searched, and make certain moves in the problem spaces more immediate. We invoke Gentner's (1983) theory of structure mapping to explain how these advantages are attained. We also examine several characteristic pitfalls of representations in this style.     

Persistence and withdrawal by students in a preservice science and mathematics teacher education course

At a time when recruitment into preservice teacher education courses in mathematics and science is difficult, one strategy to increase the number of graduates is to minimise the number of students who fail to complete their university courses. This study sought to determine factors which distinguish withdrawers from persisters in the first semester of a B.Ed course. Discriminant analysis was employed; a discriminant function employing seven factors resulted in correct classification in 81% of cases. Further analysis distinguishing between dropouts and transferees resulted in two discriminant functions with some common variables. Specializations: Science Education, Pedagogy.

Learning with collaborative inquiry: a science learning environment for secondary students

When inquiry-based learning is designed for a collaborative context, the interactions that arise in the learning environment can become fairly complex. While the learning effectiveness of such learning environments has been reported in the literature, there have been fewer studies on the students’ learning processes. To address this, the article presents a study of science learning in a computer-supported learning environment called Collaborative Science Inquiry (CSI), which integrates guided inquiry principles for activity design, employs modelling and visualisation tools for promoting conceptual understanding and incorporates key computer-supported collaborative learning (CSCL) elements for enabling students’ collaboration. With the aim of understanding the process of students’ conceptual changes supported by the CSI learning environment as used in a secondary school, data on students’ test achievements, responses to learning tasks and peer discussions in collaboration were collected, analysed and discussed. The results of the qualitative and quantitative data analysis indicated that guided inquiry coupled with CSCL elements facilitated by the CSI system can engage students in inquiry activities and promote their conceptual understanding in a progressive way.     

RESEARCH SECTION: Curriculum integration and at‐risk students: a Canadian case study examining student learning and motivation

The combining of subject areas or disciplines, referred to in this article as curriculum integration, has been recognised as being linked to high levels of student motivation and learning. Sheryl MacMath of the University of Toronto, Jillian Roberts of the University of Victoria, and John Wallace and Xiaohong Chi of the University of Toronto discuss the findings of their case study (n = 23 students) based in a Canadian secondary school where an integrated unit on energy was taught to pupils identified as being ‘at risk’ of not completing high school. Teacher and student interviews, classroom observations and surveys were used in the case study to investigate student motivation and learning. Results from the study illustrate that students experienced higher levels of motivation and academic success compared to work on previous units. The authors explore how higher levels of student self‐efficacy were also recorded due to the repetition of content in different classrooms and across different contexts. The authors argue that further research in this area should examine more than student learning and motivation and highlights the need to focus specifically on opportunities for successful academic experiences where student efficacy is increased.     

Inquiry-based science education: towards a pedagogical framework for primary school teachers

Inquiry-based science education (IBSE) has been promoted as an inspiring way of learning science by engaging pupils in designing and conducting their own scientific investigations. For primary school teachers, the open nature of IBSE poses challenges as they often lack experience in supporting their pupils during the different phases of an open IBSE project, such as formulating a research question and designing and conducting an investigation. The current study aims to meet these challenges by presenting a pedagogical framework in which four domains of scientific knowledge are addressed in seven phases of inquiry. The framework is based on video analyses of pedagogical interventions by primary school teachers participating in open IBSE projects. Our results show that teachers can guide their pupils successfully through the process of open inquiry by explicitly addressing the conceptual, epistemic, social and/or procedural domain of scientific knowledge in the subsequent phases of inquiry. The paper concludes by suggesting further research to validate our framework and to develop a pedagogy for primary school teachers to guide their pupils through the different phases of open inquiry.

Data-based individualization in mathematics to support middleschool teachers and their students with mathematics learning difficulty

Project STAIR (Supporting Teaching of Algebra: Individual Readiness) aims to develop and iteratively refine a framework for using data-based individualization (DBI) to support the readiness for algebra of middle-school students with mathematics learning difficulty. Project STAIR was tested in four middle schools in the United States to assess the impact of intensive professional development, ongoing coaching, and frequent student progress monitoring on teachers’ DBI practices, school-level culture and climate, and students’ algebra readiness. Findings from this exploratory research point to the promise of Project STAIR for improving teacher perceptions of school culture and climate related to support of students experiencing mathematics learning difficulty as well as increasing specific DBI practices, including teachers’ ratings of importance, understanding, and confidence with assessment practices. Students’ mathematics outcomes improved on several algebra-readiness progress monitoring measures, along with a diagnostic measure, but not on a more distal measure of mathematics performance.     

Connecting distance learning communities to research via virtual collaboratories: a case study from library and information science

This case study reports on patterns of participation in a virtual collaboratory organised around goals associated with the involvement of graduate students in research and writing projects. Traditionally, distance learning classrooms have been devoted to teaching content matter (in a virtual context) yet this case study reports on the use of synchronous learning contexts to support research and professionalisation on the part of graduate students in library and information science. Focus is placed on discussing virtual collaboratories as a form of learning design that modifies the use of existing (synchronous) distance learning classrooms.
