A study of student outcomes and teacher characteristics in exemplary middle and junior high science programs

Recent efforts of the National Association for Research in Science Teaching (NARST) and the National Science Teachers Association (NSTA) have encouraged collaborative “research partnerships” between university researchers and classroom science teachers. This research partners study, begun in 1987, examined student outcomes and teacher characteristics in middle/junior high exemplary programs identified by the NSTA's Search for Excellence in Science Education (SESE). A second year of the study has been completed involving SESE program teachers with similar instructional profiles. Using Iowa Test of Basic Skills and National Assessment of Educational Progress (NAEP) items, key teachers in those SESE programs examined their seventh- and eighth-grade student outcomes in three domains: (a) knowledge, (b) attitudes, and (c) applications/connections. Results were compared with national populations. A similar study was conducted during the second year, involving teachers from the first year and additional teachers with instructional practice profiles similar to those in SESE programs. Teachers were surveyed using a questionnaire from the Report of the 1977 National Survey of Science, Mathematics and Social Studies Education Teachers (Weiss, 1978a) and supplemental questions (Bonnstetter, 1985). This study found that in exemplary middle/junior high programs: (a) as a group, students achieve high scores in science knowledge and maintain or develop positive attitudes toward science; and (b) students need opportunities to make connections between what they learn in science and personal responsibility.     

Factors which deter potential science/math teachers from teaching; changes necessary to ameliorate their concerns

In light of the perceived national need for more science and math teachers, this study was conceived to:

• 1. Identify “teaching oriented” students among freshmen at a mid-western engineering school, who have chosen NOT to become teachers;
• 2. Find out what reasons these “potential” science and math teachers have for deciding not to pursue teaching careers;
• 3. Determine what amelioration of these problems would be necessary for them to no longer be factors which would inhibit students from becoming teachers.

Of a random sample of 110 students drawn from a freshman class, 98 participated fully in the study. Each participant took Holland's Self-Directed Search to determine “teaching orientation” and author-constructed instruments to assess their concerns about teaching. Results showed “teaching oriented” students avoided teaching due to low starting salaries, lack of job security, low maximum salaries, not wanting to do the work teacher's do, poor job availability and discouragement by family and friends. Starting salaries of $21,693 and salaries of $32,600 for a teacher with a B.A. and 10 years experience were among the changes deemed necessary to make teaching attractive.     

Interaction between examination type,anxiety state,and academic achievement in college science; an action-oriented research

The trait anxiety profile of future science teachers, as well as their preferences concerning types of examinations in science and mathematics, have been surveyed prior to the administration—within the various science courses—of several traditional and nontraditional types of examinations and the assessment of students' state anxieties as well as their respective performance, i.e., their academic achievements. Our major findings are that

• (a) Our students prefer by far examinations in which the emphasis is on understanding and analyzing rather than on knowing and “remembering,” that the use of any relevant material during the examinations be permitted, and that the time duration be practically unlimited (e.g., “take-home”–type examinations).
• (b) Students' state anxiety correlates with the type of the examination, with a tendency towards somewhat higher anxiety for females. The preferred types of examinations reduce test anxiety significantly, and result in higher grades accordingly.
• (c) The reduction of anxiety and the improvement in achievements as a function of the examination type are far more significant for low achievers compared with medium and high achievers.
• (d) Although teachers are aware of the student preferences, they persist in giving their students their own “pet”-type examinations.

These results are discussed in terms of the implications for upgrading both science education and college student testing and assessment mechanisms.     

Meeting the Demands of the Workplace: Science Students and Written Skills

Over the last 15 years, surveys in a range of English-speaking countries, from North America and the United Kingdom, to New Zealand and Australia, have consistently shown that employers rank oral and written communication skills as highly as or more highly than any technical or quantitative skills. However, in New Zealand there has been very little research into determining exactly what is meant by the “written communication skills” employers state they desire. A further issue in this research to date has been a lack of differentiation between employers—no study has specifically targeted the requirements of employers of science graduates. This article reports the findings of ongoing research into the expectations of science students and of employers of science graduates, and centers around several key questions:

• What do New Zealand employers of science graduates specifically want in terms of their new hires' writing skills?
• How can information gained from employers of science graduates be used to motivate science students to take seriously the need to develop their writing skills?
• How can writing programs be evaluated and developed to help science students acquire communication skills that are important for their future learning and for their employment and promotion prospects?

Findings are compared with the findings of the 2004 National Commission on Writing's survey of American businesses.

     

Metacognition in Mathematical Problem Solving

Metacognition is considered by most educationists as an element necessary for many cognitive tasks. In problem solving, it has been said that possessing knowledge alone is insufficient and problem solvers need to exhibit high level cognitive skills like “self-regulation skills” (also known as metacognitive strategies) for successful problem solving.

A study on students' metacognitive strategies was carried out with over a thousand secondary and pre-university students from 12 schools. A questionnaire adapted from Biggs (1987) was administered to students at various levels (Secondary 2, Secondary 4, Pre-University 1), from different academic tracks (General, Science, Arts) and academic streams (Special, Express, and Normal). They were required to self-report on their metacognitive beliefs; their use of metacognitive strategies in mental tasks involving memory, problem solving and comprehension; and their attitudes towards the learning of various academic subjects. 20 items from the questionnaire which were related to problem solving were categorized into four stages, namely, orientation, organisation, execution and verification and data from these items were analysed.

Some findings that emerged were:

• (a) Normal stream students exhibited a lower usage of metacognitive strategies as compared to students from the Express and Special streams.

• (b) Metacognitive strategies used by Normal stream students tended to be of the “surface” type.

• (c) There was no significant difference in the frequency of usage of metacognitive strategies between students from different academic tracks.

• (d) During the problem solving process, students spent most time on evaluation of answers rather than on monitoring their understanding.

• (e) Students from different levels (Secondary 2, Secondary 4 and Pre-University) exhibited similar frequency of usage of metacognitive strategies in problem solving.

• The implications of these findings on future research and development projects as well as the teaching of metacognitive strategies are discussed in the paper.

     

Exploring Exemplary Elementary Teachers’ Conceptions and Implementation of Inquiry Science

This study was an exploration of the conceptions of inquiry science held by exemplary elementary teachers. The origins of these conceptions were explored in order to establish how best to improve elementary teachers’ understanding and implementation of inquiry science teaching. Four focus group sessions were held as well as classroom observations. Data were also collected through surveys and interviews. The six exemplary teachers in this study held ideas about inquiry as “finding things out” and all described themselves as having been children who explored and experimented with the world around them. The teachers provided information about successful classroom environments and attitudes that they use to achieve strong inquiry science learning. The teachers had a number of recommendations for helping other teachers become inquiry science teachers and suggestions for professional development for teachers are made based on these recommendations.     

Identifying exemplary science teachers through their students’ perceptions of the assessment process

This paper reports on part of a large‐scale study aimed at examining students’ perceptions of assessment. This paper will report on a study utilising mixed methodology in 150 Australian middle school classrooms. The purpose of the study described in this paper was to use the Students’ Perceptions of Assessment Questionnaire on Teacher Interaction (SPAQ) to identify and describe exemplary science teachers. With a sample of over 3000 science students, the reliability of the SPAQ scales ranged from 0.62 to 0.82. The exemplary teachers were identified as those whose students’ perceptions were more than one standard deviation above the mean on three of the five scales of Congruence with planned learning, Transparency, Authenticity, Student consultation, and Diversity. The construct validity of the SPAQ to identify these exemplary teachers was confirmed through interviews with students and these views are reported in the article.     

Science educators' perceptions of problems facing science education: A report of five surveys

Five groups of science educators representing faculty at graduate institutions, graduate students, teachers, supervisors, and leadership conferees were surveyed concerning their perceptions of current problems facing science education. A total of 144 participants provided an average of 4.7 responses. The responses were tabulated using an emergent set of categories that resulted in six major groupings, i.e. conceptual, organizational, teacher; related, student-related, university, and societal. The category with the most problems identified was in the area of conceptual problems. University related problems and organizational problems were the next two most frequently mentioned categories for problems. Specific problems in all categories most often cited include the following:

• 1 confusion and uncertainty in goals and objectives;
• 2 lack of vision and leadership in schools and universities;
• 3 absence of a theoretical base for science education;
• 4 poor quality teacher education programs;
• 5 inappropriate avenues for continuing education of teachers;
• 6 limited dialogue between researchers and practitioners;
• 7 declining enrollments;
• 8 poor quality teaching and counseling;
• 9 insufficient programs in science for the wide spectrum of students; and
• 10 public and parental apathy towards science.

     

Attitudes toward science of gifted and nongifted fifth graders

The purpose of this investigation has been to explore whether differences existed between gifted and nongifted fifth graders and between genders and related subgroups with respect to attitudes toward science. Both groups (N = 25) were matched on the demographic characteristics of school-site, race, sex, and socio-economic background. Gifted students were found to have more positive attitudes toward science than nongifted students; however, no significant differences were found. In all cases, boys (all boys, gifted boys, and nongifted boys) exhibited more positive attitudes toward science; again, no significant differences were uncovered between the boys and their counterpart group or subgroups. The item which consistently reflected the most positive rating (gifted students, all boys and gifted boys, and all girls and nongifted girls) was “usefulness of things done in science class.” Items where discrepancies surfaced included “usefulness of science when playing at home” where nongifted students and gifted girls were significantly more positive than their counterparts, and “spending more time doing science experiments” where all boys and gifted boys were significantly more positive than their counterparts.     

Age and intergroup differences in attitudes toward the teaching profession: How do teachers and students view themselves and each other?

Differences in attitudes toward the profession were determined among samples of teachers varying in CA and between teachers and students enrolled in teacher education programs. The students rated items reflecting “altruistic” and “pragmatic” needs met by teaching in terms of their importance in selecting teaching as a career and in terms of the way they perceived experienced teachers would rate them. The teachers rated the items in terms of their importance in their present teaching career and as they thought current students would rate them. The results indicated the absence of age differences in attitudes among the teacher samples. However both objective (self) and perceived intergroup differences in attitudes were found between the student and teacher samples. These results provide strong support for Neugarten's hypothesis that differences in the behavior and attitudes of adults reflect changes in social states rather than developmental differences and that the hypothesis can be generalized both to self and perceived intergroup differences in attitudes.     

Evaluation of a model science teacher education program

This study assessed the effectiveness of one science teacher education program designed to be a model program. The study provided evidence that preservice science teacher education can have a very positive effect on the development of preservice science teachers into effective practicing teachers. Thirty program graduates completed a pilot version of the 1985 National Survey of Science and Mathematics Education providing information on course objectives, teaching strategies, equipment use, time allocation, and textbook use. The responses of program graduates were compared to the responses of a select national sample of teachers. All teachers in the comparison group were from programs in the Search for Excellence in Science Education, Presidential Award winners, recognized as outstanding state science teachers, employed as department chairs, or actively involved in the development of science curriculum. Analysis of the responses indicated that both program graduates and comparison group teachers had similar course objectives and teaching strategies, used materials and equipment a similar amount of time, and allocated class time in similar ways. In another component of the study, students of 37 program graduates completed a questionnaire that assessed their attitudes toward science teachers, science classes, and the study of science. Analysis of attitudinal data from their 2871 students indicated that students of program graduates generally had positive attitudes. For instance, 89% of the students perceived their science teacher as asking questions and 80% perceived their science teacher as letting them ask questions. In general, the data are in stark contrast to the images obtained from National Assessment efforts.     

First‐year Pre‐service Teachers in Taiwan—Do they enter the teacher program with satisfactory scientific literacy and attitudes toward science?

Scientific literacy and attitudes toward science play an important role in human daily lives. The purpose of this study was to investigate whether first‐year pre‐service teachers in colleges in Taiwan have a satisfactory level of scientific literacy. The domains of scientific literacy selected in this study include: (1) science content; (2) the interaction between science, technology and society (STS); (3) the nature of science; and (4) attitudes toward science. In this study, the instruments used were Chinese translations of the Test of Basic Scientific Literacy (TBSL) and the Test of Science‐related Attitudes. Elementary education majors (n = 141) and science education majors (n = 138) from four teachers’ colleges responded to these instruments. The statistical results from the tests revealed that, in general, the basic scientific literacy of first‐year pre‐service teachers was at a satisfactory level. Of the six scales covered in this study, the pre‐service teachers displayed the highest literacy in health science, STS, and life science. Literacy in the areas of the nature of science and earth science was rated lowest. The results also showed that science education majors scored significantly higher in physical science, life science, nature of science, science content, and the TBSL than elementary science majors. Males performed better than females in earth science, life science, science content, and the TBSL. Next, elementary education majors responded with more “don’t know” responses than science education majors. In general, the pre‐service teachers were moderately positive in terms of attitudes toward science while science education majors had more positive attitudes toward science. There was no significant difference in attitudes between genders. Previous experience in science indicated more positive attitudes toward science. The results from stepwise regression revealed that STS, the nature of science, and attitudes toward science could explain 50.6% and 60.2% variance in science content in elementary education and science education majors, respectively. For science education majors, the first three scales—the nature of science, health science and physical science—determined basic scientific literacy. However, for elementary education majors, the top three factors were physical science, life science and the nature of science. Based on these results, several strategies for developing the professional abilities of science teachers have been recommended for inclusion in pre‐service programs.     

Science Process Skills and Cognitive Preference Styles

The study examined the differences in cognitive styles between two comparable groups of students at the Grade 9 (Secondary 3) level, namely the LSS (Lower Secondary Science) group who had been exposed to the practical-based, inquiry-oriented type of science and the non-LSS group of students who had studied the more traditional type of science in the “old” science curriculum. Their differences in science achievement are measured by the common IEA Science Paper-Pencil, Multiple Choice Criterion Test and also, by the Science Process or Practical Test (which measured three levels of process skills, such as the observation/manipulation, reasoning and investigation skills). Variance in science achievement thus measured is examined against the 4 cognitive preference styles of the students, (measured by the Combined Cognitive Preference Inventory) namely the “recall”, “principles”, “applications” and “questioning” modes of thinking. The findings indicated that (a) the attainment of the science process or practical skills was characterised by the type of science curriculum (LSS or non-LSS) and it was significantly associated with the achievement level of students, (b) the cognitive preference pattern covaried according to the students' level of science achievement and the type of curriculum and (c) the weak but significant relationship between performance in the science practical skills and the students' modes of cognitive style have important implications for teachers who are concerned about the intended effects of changes in the science curriculum on the consequent learning behaviour or cognitive outcome of their students.     

Implications of a comparative assessment of exemplary and novice elementary teachers

Conclusion This study points to the fact that it would be practical to compare and assess the instructional strategies of exemplary and novice elementary science teachers using a set of criteria derived from published teacher effectiveness studies. According to this study there are differences ranging from significant to null between the instructional behaviors of exemplary and novice teachers, and it indicates that it may not be appropriate to rely entirely upon the findings of individual teacher effectiveness studies to prepare effective preservice teachers. Science teacher educators need to focus more directly on the differences in instructional strategies between the exemplary and novice teachers and inquire further into determining the causes for the differences. Hurd (1982) reported that about half of the elementary teachers studied believe that their preservice education failed to prepare them to teach science in real classrooms. If what separates exemplary teachers from novices can be clearly identified, then the science teacher educator’s task of preparing effective preservice teachers will be an easier one. Then it would be also possible to develop effective preservice science teacher education programs more congruent with exemplary science teaching practices and augment the existing science teacher education knowledge base through further research.     

An Empirical Examination of the Warfare Metaphor with Respect to Pre-Service Elementary Teachers

Since its origination in the late nineteenth century, the warfare metaphor has been used to characterize the relationship between science and religion, especially orthodox Christianity. Though thoroughly discredited by historians of science, the ideological descendants of Thomas Huxley, who spoke of science in quasi-religious terms, have kept the warfare metaphor alive. On the other hand, there are substantial numbers of Christians who at least appear to oppose science given their high-profile opposition to the general theory of evolution. The research reported in this paper asked, “Does anti-science sentiment increase with increasing orthodox Christian belief?” Two validated, published instruments were used: The Thinking about Science Survey Instrument and the Christian Fundamentalist Belief Scale. The subjects for the study were 545 preservice elementary teachers. The analysis did not show that anti-science sentiment increases with increasing Christian belief. Subjects with strong Christian beliefs were found to be just as supportive of science, if not more so, than subjects with no Christian beliefs. The study concludes with a caution against projecting attitudes toward science “on the whole” based on attitudes specifically toward evolution when working with preservice elementary teachers. Such a projection could well be counterproductive. The study has implications for other modern countries having highly religious populations such as Turkey.     

An Analysis of Teacher Discourse that Introduces Real Science Activities to High School Students

Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students’ interests in participating in opportunities to do real science? What are the discursive resources they draw on to introduce authentic science to students? The purpose of this ethnographic and discourse-analytic study is to investigate the ways in which the activities of scientists are discursively presented to high school students in a biology/career preparation course. Data sources were collected by means of observation, field notes, interviews, and videotaped lessons in an eleventh-grade biology/career preparation course. Drawing on discourse analysis, we investigate the discursive resources—or, more specifically and technically, the interpretative repertoires—teachers used to explain and promote opportunities to engage students in real science activities. Our analysis identifies and characterizes six types of interpretative repertoires: specialized, a-stereotypical, relevant, empirical, emotive, and rare-opportunity. To better understand the “big picture” of how these discursive resources are drawn on in the classroom, we also report on the frequencies of the repertoires in the discourse and the ways in which repertoires changed in the course of teacher-student interactions. The findings of this case study offer teachers and researchers with a better understanding of how specific forms of discourse—i.e., the repertoires—can serve as resources to enhance teacher-introduction of authentic science to students and provide students a bridge between school and authentic science.     

Elementary mathematics teachers’ judgment accuracy and calibration accuracy: Do they predict students’ mathematics achievement outcomes?

In this study we investigated whether elementary mathematics teachers’ knowledge of their students, as reflected in both the accuracy and confidence with which they are able to estimate their students’ task-specific performance on sets of mathematics problems, predicted students’ overall mathematics achievement. Thirty-nine teachers made predictions about the performance of a random sample of target students (n = 150) in their classrooms on sets of “easy” and “difficult” multiplication and division problems. Teachers also provided confidence ratings for those judgments. From these data, indicators of teachers’ judgment accuracy, judgment confidence and calibration accuracy (a measure of metacognitive monitoring) were then related to all of their students’ (n = 834) performance on year-end standardized mathematics achievement tests. Multilevel analyses indicate that teachers’ calibration accuracy, but not their task-specific judgment accuracy, significantly predicted students’ mathematics achievement. Implications for future research on teacher knowledge as well as professional development programs are discussed.     

Identifying exemplary science teachers through students’ perceptions of their learning environment

The purpose of this study was to examine students’ psychosocial perceptions of their science classroom learning environment in order to identify exemplary teachers. This mixed-method study used the valid and reliable What Is Happening In this Class? (WIHIC) questionnaire with over 3,000 middle school students in 150 classrooms in Australia. Exemplary teachers were defined as those whose students’ perceptions were more than one standard deviation above the mean for three of the five scales of Student Cohesiveness, Teacher Support, Involvement, Task Orientation and Equity. The reliability of the WIHIC scales ranged from 0.75 to 0.87. Eta² showed that the WIHIC was able to distinguish between the perceptions of the students in the classroom. The construct validity of the WIHIC for identifying these exemplary teachers was confirmed through interviews with students and these views are reported in the article.     

A study of practical‐moral knowledge in science teaching: Case studies in physical science classrooms

This study further extends a conceptual framework that explores science teaching as a “practice” not reducible to the application of formal knowledge, but as informed by teachers' practical‐moral knowledge. A hermeneutic model was developed to examine practical‐moral knowledge indirectly by investigating teachers' commitments, interpretations, actions, and dialectic interactions between them. The study also aimed to analyze teachers' actions in terms of their interpretations and commitments as they realize “internal goods” of their practice. Ethnographic case studies of three science teachers were conducted through classroom observation, in‐depth interviews and dialogues, and artifact analysis. A commitment of preparing students for national exams was common to the three teachers but was manifested differently in classroom practices. This commitment originated from interpretations about the duty of “good” teachers not letting students and schools down. Other emergent commitments were commitments: to conceptual understandings, to “challenge” learners, and to social modeling. We present each with associated interpretations and actions. The concepts of practical wisdom (phronesis) and gap closing are used to characterize teachers' practical knowledge and its development respectively. Implications for teacher education are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 929–951, 2010     

Science teachers' pedagogical content knowledge development during enactment of socioscientific curriculum materials

The purpose of this study is to provide insight into short-term professionalization of teachers regarding teaching socioscientific issues (SSI). The study aimed to capture the development of science teachers' pedagogical content knowledge (PCK) for SSI teaching by enacting specially designed SSI curriculum materials. The study also explores indicators of stronger and weaker development of PCK for SSI teaching. Thirty teachers from four countries (Cyprus, Israel, Norway, and Spain) used one module (30–60 min lesson) of SSI materials. The data were collected through: (a) lesson preparation form (PCK-before), (b) lesson reflection form (PCK-after), (c) lesson observation table (PCK-in-action). The data analysis was based on the PCK model of Magnusson, Krajcik, and Borko (1999). Strong development of PCK for SSI teaching includes “Strong interconnections between the PCK components,” “Understanding of students' difficulties in SSI learning,” “Suggesting appropriate instructional strategies,” and “Focusing equally on science content and SSI skills.” Our findings point to the importance of these aspects of PCK development for SSI teaching. We argue that when professional development programs and curriculum materials focus on developing these aspects, they will contribute to strong PCK development for SSI teaching. The findings regarding the development in the components of PCK for SSI provide compelling evidence that science teachers can develop aspects of their PCK for SSI with the use of a single module. Most of the teachers developed their knowledge about students' understanding of science and instructional strategies. The recognition of student difficulties made the teacher consider specific teaching strategies which are in line with the learning objectives. There is an evident link between the development of PCK in instructional strategies and students' understanding of science for SSI teaching.
