Women's experiences in the engineering laboratory in Japan

This qualitative study aims to examine Japanese women undergraduate engineering students’ experiences of interacting with departmental peers of the same year in the laboratory setting by using interview data of 32 final-year students at two modestly selective national universities in Japan. Expectation state theory that explains unequal relationship between men and women is used as a framework. Findings suggest that women generally had a discouraging experience while working with their male peers. Specifically, women participated less and lost confidence by comparing with the men who appeared to be confident and competent.     

An analysis of global problem issues in sixth-and seventh-grade textbooks

The study examines the extent to which the global issues of population growth, world hunger, air quality and atmosphere, and water resources were treated in sixth- and seventh-grade science textbooks. Ten textbooks were examined by five raters to determine the amount of content presented by different textbooks on global issues, the number of pages of content devoted to each issue, and the degree of depth in which issues were treated. Differences between grade levels were also explored. Of the 4,393 pages of content analyzed, less than 2 percent was devoted to these issues identified as the most serious human problems. No significant differences were found between textbook series. Significant differences were found in the number of pages of content presented on each issue. Most of the content fell into the categories of water resources, population growth, air quality, and atmosphere. The issue of war technology had the least amount of content. Distribution of content did not vary by grade level. Both levels addressed the issues of population growth, air quality, and water resources with a greater degree of depth than the issue of world hunger or war technology. The study concludes that the most widely used textbooks at the sixth- and seventh-grade levels avoid serious discussion of major global problems. And like the career indecision of a recent Miss America contestant, purchasers don't seem to be able to decide whether they want science textbooks to be “a brain surgeon or a movie actress.” Implications stemming from this dichotomy and its relationship to future science education curricular are also explored.

Curriculum as open-ended inquiry in higher education

Abstract

Throughout the world, education curriculum are determined and guided by knowledge perceived as being critical for the advancement of humanity. Often such progress is indicated and determined by curriculum shaped by the ways of knowing of the dominant cultural group or languages that have achieved hegemonic status in such communities, in the process marginalizing any ‘indigenous’ ways of knowing as embedded in the language of other cultures. Sometimes such curriculum have little or no connection with contemporary reality. In this article I therefore argue that inclusive curricular knowledge types are critical in education in order to enable all people, individually and collectively, to progress without being inhibited by the hegemony of so-called ‘scientific’ knowledge. I also argue that knowledge as embedded in a language is power, and should therefore be connected to reality. Using critical social theory, I propose an alternative, inclusive treatment of knowledge types in education curriculum – open-ended inquiry – in order to level the learning field for all learners, and, in so doing, to adequately prepare tomorrow's world citizenry.

Engineering design processes in seventh-grade classrooms: bridging the engineering education gap

This paper reports on some findings from the first year of a three-year longitudinal study, in which seventh- to ninth-graders were introduced to engineering education. Specifically, the paper addresses students’ responses to an initial design activity involving bridge construction, which was implemented at the end of seventh grade. This paper also addresses how students created their bridge designs and applied these in their bridge constructions; their reflections on their designs; their reflections on why the bridge failed to support increased weights during the testing process; and their suggestions on ways in which they would improve their bridge designs. The present findings include identification of six, increasingly sophisticated levels of illustrated bridge designs, with designs improving between the classroom and homework activities of two focus groups of students. Students’ responses to the classroom activity revealed a number of iterative design processes, where the problem goals, including constraints, served as monitoring factors for students’ generation of ideas, design thinking and construction of an effective bridge.     

Gender differences in responding to open-ended problem-solving questions

We reanalyzed data from published studies (Harp & Mayer, 1997, 1998; Mayer & Moreno, 1998, Mayer et al., 1995, 1996) in which college students learned about the formation of lightning, and were then given open-ended problem-solving question. When asked, “What could you do to decrease the intensity of lightning?,” females were approximately eight times more likely than males to refuse to answer on the grounds that nature cannot be altered. The pattern persisted across four data sets involving 810 participants. The results have practical implications for the design of alternative assessment instruments involving open-ended questions and theoretical implications for gender-based differences in verbal communication styles.     

Parental teaching styles in an open-ended teaching-learning environment

The present study extends earlier work on parental teaching style by making the task to be completed less structured, extending parent-child interaction over a 2 week time period, and equalizing the expertise of the parent relative to the child. Additionally, the study examines the effects of parental intrusiveness on a subsequent task. Subjects were 22 Caucasian middle class parent-child dyads. Audiorecordings were taped over a 2-week period while dyads were learning aspects of Logo computer programming. Even in this prolonged nonspecific learning situation, in which parents were encouraged to proceed at the child's pace, parents were overwhelmingly directive. Additionally, children of directive parents performed best on a subsequent generalization task.

Cultivating divergent thinking in mathematics through an open-ended approach

The purpose of this study was to develop a program to help cultivate divergent thinking in mathematics based on open-ended problems and to investigate its effect. The participants were 398 seventh grade students attending middle schools in Seoul. A method of pre- and post-testing was used to measure mainly divergent thinking skills through open-ended problems. The results indicated that the treatment group students performed better than the comparison students overall on each component of divergent thinking skills, which includes fluency, flexibility, and originality. The developed program can be a useful resource for teachers to use in enhancing their students’ creative thinking skills. An open-ended approach in teaching mathematics suggested in this paper may provide a possible arena for exploring the prospects and possibilities of improving mathematical creativity.

Nursing students' experiences and perceptions of an anatomy laboratory session: Mixed methods study

Many nursing curricula do not offer anatomy laboratories and exposure to cadaveric material. In this mixed methods study, nursing students' perceptions and experiences from an anatomy laboratory session were examined. Students from two academic nursing programs (a four-year general baccalaureate nursing program and a two-year accelerated nursing program for non-nursing baccalaureate graduates) took part in an anatomy laboratory session (N = 223). Participants' learning experiences, emotional experiences, and satisfaction with the anatomy laboratory session were assessed by their responses to closed-ended questionnaires. Participants' reasons for participation and suggestions for improvement were examined by open-ended questions. A mixed methods analysis of the data revealed a high level of satisfaction with the anatomy laboratory experience. Positive attitudes and learning experiences correlated with a sense of identification with the nursing profession. Satisfaction was positively associated with a perceived quality of learning and negatively associated with a negative emotional experience. Curiosity and self-challenge, as well as the quest for tangible, in-depth learning, were major motivators involved in the students' desire to participate in the session. Both qualitative and quantitative analyses indicated that the educational experience was significant. Therefore, it is recommended to integrate anatomy laboratory sessions into anatomy courses for nursing students. This will help to illustrate and assimilate classroom material and strengthen nursing students' sense of identification with their profession.     

Insightful learning in the laboratory: Some experiences from 10 years of designing and using conceptual labs

This paper describes a series of projects on the design and implementation of ‘conceptual labs’ aimed at developing insightful learning, following work that began in 1994/1995. The main focus has been on courses in mechanics and electric circuit theory. The approach taken in designing these innovative curricula can be described as ‘design-based research’. A common feature in these learning environments is the use of technology as a tool to aid students’ inquiry. In addition, systematic variation, based on the theory of variation, has been introduced into the design of the assigned tasks. Results from conceptual inventories have demonstrated the success of conceptual labs. In the later projects, video recording was used to study students’ courses of action in labs. This paper describes how these studies have provided insights into conditions that are critical for learning and how these insights have helped the present author and his co-workers make further improvements to learning environments.
