Higher Education Science Student Perspectives on Classroom Instructional Methods: A Pilot Study

Abstract: Constructivist‐based inquiry instruction has been popularized for several decades in primary‐ and secondary‐science education, with overwhelmingly positive results across all sciences. Importantly, higher education faculties have begun to embrace inquiry instruction in many subject areas. In fact, a growing body of literature illustrates the positive impact of inquiry instructional methods on science student achievement, such as in Food Science. While it has long been shown that student's instructional preference has a positive impact upon achievement, very little work has been done to assess college student's instructional preferences, especially in lecture‐based classes. A recent study was conducted at the Univ. of Idaho to identify student preferences of generic instructional models. Students from 4 majors (Food Science, Geological Sciences, Secondary Education, and Elementary Education) participated in the study. A 35‐question survey was developed to gather data on student's instructional strategy preferences. The data were analyzed to determine (a) instructional preferences inclusive of all majors, (b) instructional preference within each of the 4 majors, (c) a comparison of preferences of each major to other majors, and (d) gender issues within and across majors. The results suggest that there is perceived value of particular instructional methods over others, both within and across majors. In addition a gender relationship with methodology exists, particularly within certain subject areas.     

Some Illustrated Comments on Hypothesis Construction and Research

Abstract

This study investigated the cognitive preferences of first-year college students in Israel and Canada, their relationship to sex, achievement, major field of study, and career expectations, and to what extent cognitive preference styles are different for the same college students across three science disciplines: chemistry, biology, and medicine. Canadian students were found to have a much stronger reliance on memory than similar Israeli students. Students exhibited a general science cognitive preference style along with similar but not identical discipline dependent styles. No relationship could be detected between cognitive preferences and sex and only weak correlations were found with achievement. The major field of study and career expectation were correlated with cognitive preferences in the anticipated direction. The "utility" and "curiosity" scales found in earlier studies were confirmed, this time across three disciplines with both ipsative and normative data.     

The impact of Israel's class-based affirmative action policy on admission and academic outcomes

In the early to mid-2000s, four flagship Israeli selective universities introduced a voluntary need-blind and color-blind affirmative action policy for students from disadvantaged backgrounds. The program allowed departments to offer admission to academically borderline applicants who were above a certain threshold of disadvantage. We examine the effect of eligibility for affirmative action on admission and enrollment outcomes as well as on academic achievement using a regression discontinuity (RD) design. We show that students who were just barely eligible for this voluntary policy had a significantly higher probability of admission and enrollment, as compared to otherwise similar students. The affirmative action program also led to higher rates of admission to the most selective majors. Moreover, after enrollment, AA-eligible students are not falling behind academically, even at the most selective majors. Our results suggest the potential for a long-lasting impact of class-based preferences in admission on social and economic mobility.     

Israeli Students’ Conceptions of Science and Views about the Scientific Enterprise

Abstract

Israeli students’ conceptions of the nature of science and views about the scientific enterprise were studied within the framework of the Second International Science Study (SISS). Representative samples of 10, 14 and 17year‐old student, about 2000 in each, responded to background questionnaires and a battery of tests and scales. The Science Understanding Measure, a 20 item, multiple choice instrument provided data on understanding the nature of science by 14 and 17 year‐olds. An Attitude toward Science Scale provided data on the views of 10, 14 and 17 year‐olds on the importance of science to society and to individuals, the usefulness of science in everyday life and on harmful aspects of science. A comparison was made between the view of Israeli, British and USA students. The relationships of the conceptions and views of 17 year‐olds with personal, home and school variables as well as with achievement in science, intentions for further learning and career aspirations were explored as well. Based on the results and conclusions some recommendations are offered on how to enhance the understanding of science and promote more positive attitudes towards the scientific enterprise     

Science motivation questionnaire II: Validation with science majors and nonscience majors

From the perspective of social cognitive theory, the motivation of students to learn science in college courses was examined. The students—367 science majors and 313 nonscience majors—responded to the Science Motivation Questionnaire II, which assessed five motivation components: intrinsic motivation, self‐determination, self‐efficacy, career motivation, and grade motivation. Exploratory and confirmatory factor analyses provided evidence of questionnaire construct validity. The motivation components, especially self‐efficacy, were related to the students' college science grade point averages. The science majors scored higher than the nonscience majors on all of the motivation components. Among both science majors and nonscience majors, men had higher self‐efficacy than women, and women had higher self‐determination than men. The findings suggest that the questionnaire is a valid and efficient tool for assessing components of students' motivation to learn science in college courses, and that the components play a role in students' science achievement. © 2011 Wiley Periodicals, Inc.

Science Anxiety and Gender in Students Taking General Education Science Courses

Earlier studies [Mallow, J. V. (1994). Gender-related science anxiety: A first binational study. Journal of Science Education and Technology 3: 227–238; Udo, M. K., Ramsey, G. P., Reynolds-Alpert, S., and Mallow, J. V. (2001). Does physics teaching affect gender-based science anxiety? Journal of Science Education and Technology 10: 237–247] of science anxiety in various student cohorts suggested that nonscience majors were highly science anxious (SA), regardless of what science courses they were taking. In this study, we investigated science anxiety in a cohort consisting mostly of nonscience majors taking general education science courses. Regression analysis shows that the leading predictors of science anxiety are (i) nonscience anxiety and (ii) gender, as they were for different cohorts in the earlier studies. We confirm earlier findings that females are more SA than males. Chi-square analysis of acute science anxiety shows an amplification of these differences. We found statistically significant levels of science anxiety in humanities and social science students of both genders, and gender differences in science anxiety, despite the fact that the students were all enrolled in general education science courses specifically designed for nonscience majors. We found acute levels of anxiety in several groups, especially education, nursing, and business majors. We describe specific interventions to alleviate science anxiety.     

Beliefs and Attitudes about Science and Mathematics in Pre-Service Elementary Teachers,STEM, and Non-STEM Majors in Undergraduate Physics Courses

Elementary teachers often hold inaccurate beliefs about the Nature of Science (NoS) and have negative attitudes toward science and mathematics. Using a pre-post design, the current study examined beliefs about the NoS, attitudes toward science and mathematics, and beliefs about the teaching of mathematics and science in a large sample study (N = 343) of pre-service teachers receiving a curriculum-wide intervention to improve these factors in comparison with Science, Technology, Engineering, and Mathematics (STEM) and non-STEM majors in other physics courses (N = 6697) who did not receive the intervention, over a 10-year period. Pre-service teachers evidenced initially more negative attitudes about mathematics and science than STEM majors and slightly more positive attitudes than non-STEM majors. Their attitudes toward mathematics and science and beliefs about the NoS were more similar to non-STEM than STEM majors. Pre-service teachers initially evidenced more positive beliefs about the teaching of mathematics and science, and their beliefs even increased slightly over the course of the semester, while these beliefs in other groups remained the same. Beliefs about the NoS and the teaching of mathematics and science were significantly negatively correlated for STEM and non-STEM majors, but were not significantly correlated for pre-service teachers. Beliefs about the NoS and attitudes toward mathematics and science were significantly positively correlated for both pre-service teachers and STEM students pursing the most mathematically demanding STEM majors. Attitudes toward science and mathematics were significantly positively correlated with accurate beliefs about the teaching of mathematics and science for all student groups.     

The Relationship of Discipline Background to Upper Secondary Students’ Argumentation on Socioscientific Issues

In the present STEM (Science, Technology, Engineering, and Mathematics)-driven society, socioscientific issues (SSI) have become a focus globally and SSI research has grown into an important area of study in science education. Since students attending the social and science programs have a different focus in their studies and research has shown that students attending a science program are less familiar with argumentation practice, we make a comparison of the supporting reasons social science and science majors use in arguing different SSI with the goal to provide important information for pedagogical decisions about curriculum and instruction. As an analytical framework, a model termed SEE-SEP covering three aspects (of knowledge, value, and experiences) and six subject areas (of sociology/culture, economy, environment/ecology, science, ethics/morality, and policy) was adopted to analyze students’ justifications. A total of 208 upper secondary students (105 social science majors and 103 science majors) from Sweden were invited to justify and expound their arguments on four SSI including global warming, genetically modified organisms (GMO), nuclear power, and consumer consumption. The results showed that the social science majors generated more justifications than the science majors, the aspect of value was used most in students’ argumentation regardless of students’ discipline background, and justifications from the subject area of science were most often presented in nuclear power and GMO issues. We conclude by arguing that engaging teachers from different subjects to cooperate when teaching argumentation on SSI could be of great value and provide students from both social science and science programs the best possible conditions in which to develop argumentation skills.     

Relationship of sex,achievement, and science self-concept to the science career preferences of black students

Science career preferences of junior high school-aged students, while not stable predictors of ultimate career choice, do serve to direct and maintain individuals along the paths to careers in science. In this study, factors relevant to science career preferences of black eighth grade students were investigated. This issue is of particular import to blacks since they are severely underrepresented in the scientific fields. The sample consisted of 113 males and 148 females in an inner city junior high school. The Science Career Preference Scale, the Peabody Picture Vocabulary Test, and the Self-Concept of Ability Scale (Form B-Science) were administered. Mathematics and science grades were obtained from class rating sheets. Treatment of the data involved multiple regression analysis according to a hierarchical model. Results showed that of all the independent variables, sex was the strongest predictor of science career preferences, accounting for 25% of the criterion variance. The findings suggest that early adolescent science career preferences are related more to interests that are consonant with sex-role considerations than realistic assessment of mathematics or science achievement.     

Science Learning Outcomes in Alignment with Learning Environment Preferences

This study investigated students’ learning environment preferences and compared the relative effectiveness of instructional approaches on students’ learning outcomes in achievement and attitude among 10th grade earth science classes in Taiwan. Data collection instruments include the Earth Science Classroom Learning Environment Inventory and Earth Science Learning Outcomes Inventory. The results showed that most students preferred learning in a classroom environment where student-centered and teacher-centered instructional approaches coexisted over a teacher-centered learning environment. A multivariate analysis of covariance also revealed that the STBIM students’ cognitive achievement and attitude toward earth science were enhanced when the learning environment was congruent with their learning environment preference.     

Cognitive Preferences in Agriculture of Middle‐School Students and their Teachers‡

Summaries

English

A special cognitive‐preference inventory dealing with agriculture was developed, validated and administered to 943 middle‐school students and their teachers. This is the first reported study of cognitive preferences of 7th and 8th grade (12 to 13 year‐old) students. The inventory was found to be a valid and reliable measure of cognitive preferences related to agricultural topics studied in Israeli schools.

Preference for application (A) was found to be negatively correlated in different students with either recall (R) or principles (P) or critical questioning (Q).

Studying the ‘new’ agriculture compared with the ‘old’, resulted in a lower preference for R and a higher preference for A. Female students had, on the average, a higher preference for R and P while males tended to prefer A and Q. Children whose fathers were simple workers had the highest preference for R while children whose fathers were academics had the lowest preference for R. Teachers, when compared with their students, had a much higher preference for P and a much lower preference for R. A close correspondence was found between reported emphasis in classroom tests and the cognitive‐preference modes of teachers.

     

Increasing Persistence in Undergraduate Science Majors: A Model for Institutional Support of Underrepresented Students

The 6-yr degree-completion rate of undergraduate science, technology, engineering, and mathematics (STEM) majors at U.S. colleges and universities is less than 40%. Persistence among women and underrepresented minorities (URMs), including African-American, Latino/a, Native American, and Pacific Islander students, is even more troubling, as these students leave STEM majors at significantly higher rates than their non-URM peers. This study utilizes a matched comparison group design to examine the academic achievement and persistence of students enrolled in the Program for Excellence in Education and Research in the Sciences (PEERS), an academic support program at the University of California, Los Angeles, for first- and second-year science majors from underrepresented backgrounds. Results indicate that PEERS students, on average, earned higher grades in most “gatekeeper” chemistry and math courses, had a higher cumulative grade point average, completed more science courses, and persisted in a science major at significantly higher rates than the comparison group. With its holistic approach focused on academics, counseling, creating a supportive community, and exposure to research, the PEERS program serves as an excellent model for universities interested in and committed to improving persistence of underrepresented science majors and closing the achievement gap.     

Differences in the Scientific Epistemological Views of Undergraduate Students

The purpose of this study was to examine whether science and non‐science major students have different scientific epistemological views (SEVs). A multidimensional instrument previously developed by the authors was used to assess differences in college students’ SEV of various aspects. A total of 220 freshmen (42% science and 58% non‐science majors) attending two public universities participated in this investigation. Results indicated that the science majors have less sophisticated beliefs in the theory‐laden and cultural‐dependent aspects of science than non‐science majors. Analysis of variance results further revealed significant differences in SEV dimensions among the three major fields: non‐science, pure science, and science education. Science education students gained the lowest scores on the entire scale among the groups. Findings of this study imply that science major (including science education) students might be involved longer in such an epistemic environment that described scientific knowledge as objective and universal. It is also possible that beliefs about certainty and objectivity lead these students to select science as their major field. Implications for future research and science teacher education are discussed.     

Toward equity and excellence in math and science education

Two studies examined the effectiveness of an innovative program, Mathematics, Engineering Science Achievement (MESA), designed to prepare high school minority students for math-based fields. The program is noteworthy because it incorporates recommendations of educators and policymakers for improving the quality of math/science education and decreasing the underrepresentation of minorities in these fields. Study 1 showed that MESA seniors completed more math/science courses and showed higher academic performance than similar minority students. However, their verbal and mathematics performance was below seniors nationwide planning math-based college majors. Study 2 revealed that the majority of former MESA students were pursuing a math-based major at the university level and showed satisfactory postsecondary progress. Features contributing to program effectiveness and areas requiring additional action are explored.     

Science Teaching Efficacy of Preservice Elementary Teachers: Examination of the Multiple Factors Reported as Influential

This study explores the science teaching efficacy beliefs of pr-service elementary teachers and the relationship between efficacy beliefs and multiple factors such as antecedent factors (participation in extracurricular activities and number of science and science teaching methods courses taken), conceptual understanding, classroom management beliefs and science teaching attitudes. Science education majors (n?=?71) and elementary education majors (n?=?262) were compared with respect to these variables. Finally, the predictors of two constructs of science teaching efficacy beliefs, personal science teaching efficacy (PSTE) and science teaching outcome expectancy (STOE), were examined by multiple linear regression analysis. According to the results, participation in extracurricular activities has a significant but low correlation with science concept knowledge, science teaching attitudes, PSTE and STOE. In addition, there is a small but significant correlation between science concept knowledge and outcome expectancy, which leads the idea that preservice elementary teachers’ conceptual understanding in science contributes to their science teaching self-efficacy. This study reveals a moderate correlation between science teaching attitudes and STOE and a high correlation between science teaching attitudes and PSTE. Additionally, although the correlation coefficient is low, the number of methodology courses was found to be one of the correlates of science teaching attitudes. Furthermore, students of both majors generally had positive self-efficacy beliefs on both the STOE and PSTE. Specifically, science education majors had higher science teaching self-efficacy than elementary education majors. Regression results showed that science teaching attitude is the major factor in predicting both PSTE and STOE for both groups.     

Students’ Perspectives on Worldwide “Greening” of Tertiary Education Curricula

Several scholars have suggested the introduction of an environmental literacy requirement into the curricula of Non-Environmental Science disciplines in tertiary institutions of the world as a “greening” strategy for fostering global environmental stewardship necessary for enhancing understanding and collaboration in tackling the major environmental risks facing our global village today. However, there is no study on students’ opinion on this issue. This study was therefore initiated to 1) evaluate the opinion of undergraduate students on the introduction of a worldwide environmental literacy into the curricula of Non-Environmental science majors as a graduation requirement; and 2) identify any possible demographic differences in opinions among the student subjects polled. We sought the opinion of 800 undergraduates from African, North American and European universities on the subject and 99% responded. The result showed that a majority (67%) of them supported the worldwide environmental literacy requirement and those already trained were significantly (P < 0.0001) more likely to support it than those untrained. Students from developing countries were significantly (P < 0.0001) more likely to support it than those from developed countries; similarly students in the Arts’ disciplines were more likely to support it than Non-Arts’ students as a group. However, no significant differences were observed between students from Francophone versus Anglophone countries; Social Sciences versus Non-Social Sciences majors and between Education versus Non-Education majors. Some similarities were observed between the opinion of university-age students in this study and 15-year old secondary school students from two major international surveys (Research on Science Education-ROSE, and Program for International Student Assessment-PISA) on science education; further studies comparing these two categories of students is suggested. The need for all professionals to be literate about the science of their surroundings was the most identified reason for supporting the literacy requirement by the students polled. The results of this study thus provide evidence of support by students in the on-going paradigm shift towards “greening” the curricula of tertiary institutions and thus reinforces its implementation by leaders of academe and policy makers worldwide.

Disciplinary Categories, Majors, and Undergraduate Academic Experiences: Rethinking Bok’s “Underachieving Colleges” Thesis

Using data from the 2008 University of California Undergraduate Experience Survey, we show that study time and academic conscientiousness were lower among students in humanities and social science majors than among students in science and engineering majors. Analytical and critical thinking experiences were no more evident among humanities and social sciences majors than among science and engineering majors. All three academically beneficial experiences were, however, strongly related to participation in class and interaction with instructors, and participation was more common among humanities and social sciences students than among science and engineering students. Bok’s (Our underachieving colleges: A candid look at how much students learn and why they should be learning more. Princeton and Oxford: Princeton University Press, 2006) influential discussion of “underachievement’ in undergraduate education focused on institutional performance. Our findings indicate that future discussions should take into account differences among disciplinary categories and majors as well.     

Gender disparities in science and engineering in Chinese universities

Gender disparities in science and engineering majors in Chinese universities have received increasing attention from researchers and educators in China in recent years. Using data from a national survey of college students who graduated in 2005, this study documents gender disparities in enrollment and academic performance in science and engineering majors, and explores gender disparities in initial employment experiences of science and engineering graduates. It finds that females lag far behind males in enrollment in science and engineering majors overall. However, females actually are more represented than males in some majors such as mathematics and chemistry though the reverse is true for other science and engineering majors. Also, in science and engineering majors, females perform better than males in both general course grades and in English competency tests. Male science and engineering graduates have a clear advantage over their female counterparts in initial employment after graduation: they have a high employment rate, a higher starting salary, and are more likely to be employed in such jobs as business management and technical specialist. The male advantage in employment rate and starting salary persists even after controlling for other factors.     

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.
