A qualitative analysis of context-aware ubiquitous learning environments using Bluetooth beacons

The use of Bluetooth Low Energy (BLE) beacons is becoming widespread for context-aware learning environments. This technology can be used in indoor and outdoor settings such as museums, shops, home and schools in order to identify the location of learners and their contexts. Specifically, in the constructivist view of learning, learners can use such sensing technology for constructing knowledge and experiencing learning at any time, anywhere. However, exploration of such technology has been limited in the constructivist context-aware ubiquitous learning (U-learning) literature. For this purpose, the authors evaluated two android-based U-learning applications: one was an outdoor learning environment in a garden, the other was about locating books in a library. The applications were implemented and tested with school and university students. The qualitative results are presented in this article, and show how such sensing technology is promising for both pedagogical environments.     

Structural and linguistic variables in selected inference patterns for bilinguals in grades six to ten

Summary This study is a preliminary correlational study. Consequently, the statements given in the discussion are tentative and imply no cause-effect relationships. In general this study supports the idea that the ability to recognize valid principles is not a unitary ability which develops with age and levels off at a fixed age in the age range 11–16 years. For one thing, decisions made by children concerning the validity of inferences do not seem to be made solely on a formal basis but also on the kind of the linguistic structures of the natural language used. Moreover, there are structural variables which seem to reflect developmental growth and variables which do not. The most important single one in the latter is decidability, i.e., ability to recognise principles with no logically necessary conclusions. Further research is being planned with the hope of refining the model and isolating and studying different variables under experimental control.American University of BeirutThis research was supported by The Science and Mathematics Education Center (SMEC) of the American University of Beirut with funds from a Ford Foundation Grant.     

Engaging postgraduates in a peer research group at the research proposal stage in a Malaysian university: support and challenges

Due to the increasing workloads for supervisors and the challenges in research proposals for postgraduates, the study focused on engaging 15 postgraduates in a Malaysian public university in a peer research group. The data was collected from observations of the group meetings, video-recorded peer feedback and follow-up interviews. The qualitative analysis of the data indicates that the research group supported the postgraduates through peer feedback practices, learning how to present proposals and defend themselves and finding directions in research proposals. Although their engagement was challenged by initial reservations of some postgraduates to present their proposals and provide feedback and issues related to provision, reception and reliability of peer feedback, these challenges were minimized through mentoring and instructional strategies. While peer research groups represent a valuable pedagogical support that complement supervisors’ support to postgraduates in developing their research proposals, the value should be maximized by integrating supervisors in research groups.     

Problem solving activity in the workplace and the school: The case of constructing solids

The purpose of the present study is to document, compare, and analyze the nature of spatial reasoning by practitioners (plumbers) in the workplace and students in the school setting while constructing solids, with given specifications, from plane surfaces. Data were collected from a plumbing workshop and five high school students while constructing a cylindrical container of capacity one-liter and height of 20 cm. The results confirm the power of activity theory and its methodology in explaining and identifying the structural differences between the two activities in the two different cultural settings. Students and plumber activity structures differed in the operational aspect (actions) and the means and concrete conditions (operations) under which such a goal is carried out. Activity theory has the potential to explain the differences between the two activities in terms of differences in the motive, social-cultural settings, the tools that were available and accessible which resulted in different actions, and the constraints (operations) under which the task was executed. Theoretical and pedagogical implications were identified. This revised version was published online in July 2006 with corrections to the Cover Date.     

INTEGRATING PHYSICS AND MATH THROUGH MICROCOMPUTER-BASED LABORATORIES (MBL): EFFECTS ON DISCOURSE TYPE,QUALITY, AND MATHEMATIZATION

The purposes of this study were to understand the nature of discourse in terms of knowledge types and cognitive process, source of utterances (student or teacher), and time use in microcomputer-based labs (MBL) and verification type labs (VTL) and to gain an understanding of the role of MBL in promoting mathematization. The study was conducted in 2 grade 11 classes in which students studied Hooke’s law and Newton’s second law of motion using MBL during 1 year while a different group of students studied the same topics with the same physics teacher using a VTL approach. All sessions were videotaped, transcribed and coded using a taxonomy developed by DeVito & Grotzer (2005). In addition, evidence to support each of the 5 steps of mathematization was sought from the actions of the teachers and their discourse with the students. Results showed that conceptual knowledge type utterances were significantly more frequent in MBL sessions, cognitive processes of remembering and understanding were significantly more frequent in the MBL sessions, students spent most of their time analyzing the graphs in the MBL sessions, and MBL has a potential to promote mathematization in favorable instructional environments in physics laboratory classes.     

Teachers’ ability to identify and explain students’ actions in near and far figural pattern generalization tasks

The purpose of this paper is to explore middle school in-service mathematics teachers’ ability (1) to identify and explain students’ actions in pattern generalization and (2) to account for the variation in teachers’ explanations of students’ actions in terms of task and teachers’ factors. Two questionnaires were developed: (1) a questionnaire to measure teachers’ ability to identify students’ actions while finding the nth term in the pattern generalization and (2) a questionnaire to measure teachers’ ability to explain students’ actions in different tasks. The two questionnaires were given to a sample of 83 middle school in-service mathematics teachers from 22 schools in Lebanon. Analysis of data shows that teachers seemed to have the ability to identify students’ actions while finding the nth term in the pattern generalization and that teachers’ explanations of students’ actions in different tasks are lacking in terms of identifying variable-related counting elements. The results of stepwise multiple regression show that teachers’ ability to explain students’ actions to find the general term depends on their ability to explain students’ step-by-step counting or drawing.     

Trends in the development of student level of reasoning in pattern generalization tasks across grade level

This paper explored (1) the developmental trend of student level of reasoning across grade level in pattern generalization; (2) the mediatory role of task variables in the developmental trend of student level of reasoning within and across tasks; and (3) developmental trend of student level of reasoning associated with strategy use across grade level. A test designed to measure student level of reasoning was given to a sample of 1232 students from grades 4 to 11 from 5 schools in Lebanon. The Structure of the Learned Outcomes or Responses (SOLO) was used as a theoretical model. Results show that student level of reasoning exhibited an increasing trend across clusters of grade levels and that there were several SOLO levels in each cluster of grade levels. Type of task (immediate, near, far) and function type (linear, non-linear) seem to mediate the development of level of reasoning across grade level but the complexity of the task (simple, more complex) did not. Students used several strategies in each cluster of grade levels and the developmental trends of student level of reasoning associated with strategy use were not uniform and varied across clusters of grade levels, thus supporting a neo-Piagetian interpretation of the results.     

Contrasting Perspectives and Performance of High School Students on Problem Solving in Real World, Situated, and School Contexts

This study describes and contrasts theoretically and empirically problem solving of situated problems in school and the real world at the macro level as a social-cultural activity system and analyzes the process of solving situated problems by high school students at the micro level as an activity. Three potentially experiential problem tasks were given to 31 last year high School science students. Action map, a concept derived from activity theory, was used to represent the solutions. Qualitative methods were used to analyze the data obtained from the written solutions as well as interviews with the participants. Leont'ev's activity theory and Engeström's activity system were used as frameworks to analyze and interpret the data. The results indicate that there are fundamental identifiable differences among the activities and the activity systems of problem solving in the real world, situated, and school contexts.     

Can we engage postgraduates in active research methodology learning? Challenges,strategies and evaluation of learning

ABSTRACT

Due to the complex nature of research methodology courses, the current study focused on implementing the active teaching and learning approach to a postgraduate research method course in a Malaysian university over an academic semester. A qualitative analysis of observations, instructor-learner interactional exchanges, students’ drafts of tasks and pre-course and focus group discussion was performed. The findings revealed three types of challenges: student-oriented challenges, subject-matter-related challenges and instructor-oriented challenges. Three main pedagogical strategies: instructional scaffolding, peer scaffolding and engaging the postgraduates in drafting their tasks were employed as a response to these challenges. Although the active teaching and learning practices resulted into students’ enhancement of the assigned research methodology tasks and positive research learning experience, such practices were time and effort-consuming. Therefore, future research will need to examine the applicability of our active teaching and learning approach to research methodology courses in different contexts.
