The effect of portfolios on students' learning: student teachers' views

This study reports on student teachers' views of portfolios as a learning tool when they are combined with a weekly test conducted at the end of each lesson to help student teachers self‐evaluate. Student teachers' written reflections during the process provided data for the study. Analysis of the data showed that a majority of student teachers initially felt that compiling a portfolio would be time‐consuming and an extra burden added to their already busy schedule. However, later on they all found that the process was a useful learning experience. Moreover, the portfolio process – especially combining self‐reflection with weekly tests – encouraged students to study regularly, increased retention and made learning more enjoyable. Suggestions for the successful portfolio implementation include the following: guiding students both at the beginning of and during the process, providing continuous and prompt feedback during the process and making self‐reflection – especially guided by reflection prompts – an essential part of the process.     

College students' views on criminal justice

We surveyed 683 college students to examine their attitudes toward the death penalty, other criminal sanctions, and the war on drugs. College seniors were consistently less likely than freshmen to hold punitive views; this suggests a “liberalizing” effect of the college experience. This liberalizing college effect on attitudes toward criminal justice was not apparent for criminal justice majors, however, particularly when criminal justice seniors' attitudes toward the death penalty were compared with those of freshmen in criminal justice. The views of criminal justice majors overall did not differ appreciably from other students' views. We found no support for the expectation that criminal justice majors with experience in criminal justice would express more conservative, more punitive views than would criminal justice majors in general.     

A structural analysis of students' epistemic views

Student responses to a structured questionnaire concerned with views on mathematical knowledge, activity and learning, were analysed and interpreted using factorial techniques. The constructs which emerge from the analysis may provide heuristically useful for understanding student beliefs. The findings suggest that there is no simple systematic relationship between beliefs about the nature of mathematical knowledge and activity and about the teaching and learning of mathematics.     

Physics students' epistemologies and views about knowing and learning

Classrooms are complex environments in which curriculum, students, and teachers interact. In recent years a number of studies have investigated the effect of teachers' epistemologies on the classroom environment, yet little is known about students' epistemologies and how these interact with those of teachers. The purpose of this study was to document students' epistemologies and their concurrent views about knowing and learning. Using a written essay, short-answer responses to statements, a preferred classroom environment inventory, and interviews, students' views on scientific knowledge and their own knowing and learning were collected from 42 students in three sections of an introductory physics course. Our rather broad, qualitative inquiry provides a dynamic view of students' understanding of knowing and learning in high school physics. Our analyses reveal a spectrum of epistemological commitments commensurable with positions from objectivism to relativism, most of them with experientialist coloring. Even within individuals, these commitments could be at once commensurable and incommensurable with the same epistemological position. We also find rather significant inter- and intra-individual differences with respect to the consequences of a specific epistemological stance to learning, the learning strategies employed, and the learning environment preferred. Students' views on knowing and learning in physics are presented in the form of an emergent theory. The findings are discussed in terms of their application to classroom environments.

Assessing working students' college experiences: a grounded theory approach

This study explores working students' college experiences using the grounded theory approach. Focus groups were conducted to allow working students to elaborate on their college experiences, clarifying issues not easily addressed through surveys. Two theoretical propositions are offered to describe how working students are constantly searching for meaningful work as well as meaning in their work. It is important for institutions to consider work as an educationally purposeful activity outside classroom and to create job opportunities that benefit students academically, socially and financially.

Teachers' and students' views and attitudes towards a new mathematics curriculum: A case study

The education system in Portugal is in the midst of a period of intensive reform. This paper describes the findings of a qualitative case study focusing on the views and attitudes of teachers and students participating in a pilot curriculum development programme stressing active methodologies and group work, conducted by the Ministry of Education. In particular it discusses their views and attitudes about mathematics, mathematics teaching and curriculum innovation. The teachers were found to struggle with a contradiction: whilst they approved the new orientations, which were seen as adequate and innovative, they complained strongly about the design and implementation of the programme — Students had a generally positive attitude towards mathematics, although there were differences among them. The 7th graders were satisfied with their mathematics classes and with the new curriculum. The 10th graders did not consider the changes as significant in themselves, but expressed concern for their academic progress.     

College students' views of male and female college teachers: Part II—Evidence from students' evaluations of their classroom teachers

Although a majority of studies have found that male and female college teachers do not differ in the global ratings they receive from their students, when statistically significant differences are found, more of them favor women than men. Across studies, the average association between gender and overall evaluation, while favoring women (averager=+.02), is so small as to be insignificant in practical terms. Considering specific instructional dimensions of evaluations, female teachers receive very slightly higher ratings on their sensitivity to and concern with class level and progress than do men (averager=+.12). On other specific dimensions, men and women either do not differ or the differences are trivial in size (or, for two dimensions, while nontrivial, based on too few studies to be generalizable with any degree of certainty). Students tend to rate same-gendered teachers a little higher than opposite-gendered teachers. Although interaction effects on evaluations have also been found between gender of teacher and other factors (academic rank of the teacher, academic area, class level of the course, difficulty of the teacher or course, and the teacher's pedagogical orientation or personality characteristics), they are inconsistent across studies. Moreover, ratings of teachers are sometimes enhanced by gender-typical, and sometimes by gender-atypical, attributes, behaviors, and positions. The findings are discussed in terms of the expectations or demands of students and whether or not student ratings are biased by the gender of the teacher.     

The "Digital Divide": Hispanic college students' views of educational uses of the Internet

Concern has been expressed recently regarding the presence of a digital divide between majority and minority groups. Surveyed were 226 Hispanic college freshmen enrolled at a doctoral intensive institution in the Southwest regarding their attitudes toward educational uses of the Internet and their uses of technology. Statistically significant differences were found between males and females in their attitudes toward and uses of the Internet and computer technology. Differences were also revealed between students whose primary language spoken at home was English and students whose primary language spoken at home was Spanish in their attitudes toward and uses of the Internet and computer technology. Interestingly, no differences were present between first-generation and non-first-generation college students. Implications of our findings and relationships to existing literature are provided.     

Teacher education students' views on class discussion: Implications for fostering critical reflection

In an attempt to understand what factors motivate teacher education students to participate in class discussions, questionnaires were administered to students from two teacher education programs in the U.S.A. In addition, 30 students were interviewed. Findings point to the estimation of the worth of one's ideas as a key issue in class discussions. Men and older students believed that their ideas made important contributions more often than other students. Findings revealed that the topic, the classroom climate, and advance preparation are central factors influencing students' participation. The importance of fostering students' reflection about, as well as through, discussion is emphasized.     

The influence of history of science courses on students' views of nature of science

This study (a) assessed the influence of three history of science (HOS) courses on college students' and preservice science teachers' conceptions of nature of science (NOS), (b) examined whether participants who entered the investigated courses with a conceptual framework consistent with contemporary NOS views achieved more elaborate NOS understandings, and (c) explored the aspects of the participant HOS courses that rendered them more “effective” in influencing students' views. Participants were 166 undergraduate and graduate students and 15 preservice secondary science teachers. An open‐ended questionnaire in conjunction with individual interviews, was used to assess participants' pre‐ and postinstruction NOS views. Almost all participants held inadequate views of several NOS aspects at the outset of the study. Very few and limited changes in participants' views were evident at the conclusion of the courses. Change was evident in the views of relatively more participants, especially preservice science teachers, who entered the HOS courses with frameworks that were somewhat consistent with current NOS views. Moreover, explicitly addressing certain NOS aspects rendered the HOS courses relatively more effective in enhancing participants' NOS views. The results of this study do not lend empirical support to the intuitively appealing assumption held by many science educators that coursework in HOS will necessarily enhance students' and preservice science teachers' NOS views. However, explicitly addressing specific NOS aspects might enhance the effectiveness of HOS courses in this regard. Moreover, the study suggests that exposing preservice science teachers to explicit NOS instruction in science methods courses prior to their enrollment in HOS courses might increase the likelihood that their NOS views will be changed or enriched as a result of their experiences with HOS. © 2000 John Wiley & Sons, Inc.

Assessing students' disciplinary and interdisciplinary understanding of global carbon cycling

Global carbon cycling describes the movement of carbon through atmosphere, biosphere, geosphere, and hydrosphere; it lies at the heart of climate change and sustainability. To understand the global carbon cycle, students will require interdisciplinary knowledge. While standards documents in science education have long promoted interdisciplinary understanding, our current science education system is still oriented toward single‐discipline‐based learning. Furthermore, there is limited work on interdisciplinary assessment. This article presents the validated Interdisciplinary Science Assessment of Carbon Cycling (ISACC), and reports empirical results of a study of high school and undergraduate students, including an analysis of the relationship between interdisciplinary items and disciplinary items. Many‐faceted Rasch analysis produced detailed information about the relative difficulty of items and estimates of ability levels of students. One‐way ANCOVA was used to analyze differences among three grade levels: high school, college Freshman–Sophomore, college Junior–Senior, with number of science courses as a covariate. Findings indicated significantly higher levels of interdisciplinary understanding among the Freshman–Sophomore group compared to high school students. There was no statistically significant difference between Freshman–Sophomore group and Junior–Senior group. Items assessing interdisciplinary understanding were more difficult than items assessing disciplinary understanding of global carbon cycling; however, interdisciplinary and disciplinary understanding were strongly correlated. This study highlights the importance of interdisciplinary understanding in learning carbon cycling and discusses its potential impacts on science curriculum and teaching practices.

First-year engineering students' views of the nature of engineering: implications for engineering programmes

A study was conducted on the views of the nature of engineering held by 114 first-year engineering majors; the study built on prior work on views of the nature of science held by students, their instructors, and the general public. Open-coding analysis of responses to a 12-item questionnaire suggested that the participants held tacit beliefs that engineering (1) involves problem solving; (2) is a form of applied science; (3) involves the design of artefacts or systems; (4) is subject to various constraints; and (5) requires teamwork. These beliefs, however, were often unsophisticated, and significant aspects of the field of engineering as described in the literature on engineering practices were missing from the student responses. The results of this study are important because students' beliefs have a strong influence on what they value in a classroom situation, what they attend to in class, and how they choose to study for a course.     

Preservice elementary teachers' views of their students' prior knowledge of science

Pre‐service teachers face many challenges as they learn to teach in ways that are different from their own educational experiences. Pre‐service teachers often enter teacher education courses with pre‐conceptions about teaching and learning that may or may not be consistent with contemporary learning theory. To build on preservice teachers' prior knowledge, we need to identify the types of views they have when entering teacher education courses and the views they develop throughout these courses. The study reported here focuses specifically on preservice teachers' views of their own students' prior knowledge and the implications these views have on their understanding of the formative assessment process. Sixty‐one preservice teachers were studied from three sections of a science methods course. Results indicate that preservice teachers exhibited a limited number of views about students' prior knowledge. These views tended to privilege either academic or experience‐based concepts for different aspects of formative assessment, in contrast to contemporary perspectives on teaching for understanding. Rather than considering these views as misconceptions, it is argued that it is more useful to consider them as resources for further development of a more flexible concept of formative assessment. Four common views are discussed in detail and applied to science teacher education. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 45: 497–523, 2008     

Third grade African American students' views of the nature of science

This study examined the nature of science (NOS) views of lower elementary grade level students, including their views of scientists. Participants were 23 third‐grade African American students from two Midwest urban settings. A multiple instrument approach using an open‐ended questionnaire, semi‐structured interviews, a modified version of the traditional Draw‐A‐Scientist Test (DAST), and a simple photo eliciting activity, was employed. The study sought to capture not only the students' views of science and scientists, but also their views of themselves as users and producers of science. The findings suggest that the young African American children in this study hold very distinct and often unique views of what science is and how it operates. Included are traditional stereotypical views of scientists consistent with previous research. Additionally, participants expressed excitement and self‐efficacy in describing their own relationship with science, in and outside of their formal classrooms. Implications for teaching and learning NOS as it relates to young children and children of color are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 49: 1–37, 2012
