The Effect of Age and Employment on Students’ Perceptions of Online Course Quality

ABSTRACT

Three thousand, one hundred sixty students involved in online instruction at 31 colleges and universities across the United States completed a survey designed to probe into whether statements derived from 8 standards in the Quality Matters^TM (QM) rubric contributed to their success. The 43-item survey instrument measured students’ perceptions of online course quality. The effect of age and employment status on their perceptions was measured. Based on a series of ANOVA (analysis of variance)s, it was found that the highest rated standard was QM3 on Assessment and Measurement. There were significant differences between age groups. Students under 45, contrasted to those over 45, highly valued clarity and appropriateness of assessments and clear criteria for grading. For students above the age of 45, QM6 on Course Technology was valued highest. They placed a high value on the tools and media that support learning objectives and classmate interactivity. QM3 was rated highest across all employment groups—those employed part-time, full-time, and those who were unemployed. Standards 1 (Course Overview and Introduction), 2 (Learning Objectives), 4 (Resources and Materials), and 7 (Learner Support) were valued higher by students working full-time and those who were unemployed compared with those working part-time. It is likely that students who work part-time are not as focused on academics as are those who do not work. They may not be as motivated to perform well as students who work full-time. Implications for course designers and instructors are discussed.     

University Students’ Conceptualization and Interpretation of Topographic Maps

This study investigates the strategies and assumptions that college students entering an introductory physical geology laboratory use to interpret topographic maps, and follows the progress of the students during the laboratory to analyze changes in those strategies and assumptions. To elicit students’ strategies and assumptions, we created and refined a topographic visualization test that was administered before and after instruction to 26 students during the first semester of the study and to 92 students during the second semester. To more deeply understand how students think about and conceptualize topographic maps, we focused on eight individual students who were interviewed about their pretest and posttest answers as well as videotaped during three laboratory sessions. We found that even students who claim never to have worked with topographic maps often perform impressively on their pretests by making useful assumptions about symbolic topographic information. Some students, however, begin with less productive assumptions that may be unfamiliar to some instructors (e.g., thinking that the spacing of contour lines indicates elevation instead of slope). Initial success should not be misinterpreted, however, as an integrated understanding of topographic maps. Only in posttest interviews do most students express explanations integrating multiple normative assumptions. In addition to highlighting the strategies and assumptions that college students use to interpret topographic maps, we outline the implications of these findings for the design of learning objectives, curricular activities, and assessments for topographic lessons in introductory college geology courses and the training of future geoscientists.     

Geoethics: Master’s Students Knowledge and Perception of Its Importance

In the 1990s, the field of geoethics started its development, associated with a set of ethical principles that regulate the profession of geologists in their relationship with society and with nature. Given the importance of this field, but also its youth, 36 higher education students attending a Master’s of Geology course were surveyed (20 were from an educational branch and 16 were from a scientific branch). The questionnaire applied to them aimed to achieve the following goals: (a) to identify the knowledge of the respondents about this new field and to verify their position about the inclusion of geoethics in the curriculum, (b) to understand how they consider the importance of geological knowledge in political decisions and (c) to investigate possible differences in the thinking of the respondents, given the specificities of their educational branches. The study concluded that the field of geoethics is unknown to the majority of the respondents. However, the recognition of its importance was also verified, after getting familiar with the definition of the concept, as well as the need for its inclusion in formal education. The respondents also considered relevant the creation of a deontological code that could provide geologists with ethical guidance. They also considered that geology should influence political decisions, but they did not consistently recognise the limits of its influence, which seems to reveal the need of a deeper understanding of the specific nature of geological knowledge when compared with other sciences. Almost all the results were similar in both groups, but the students from the educational branch offered more elaborate answers about the issues present in the questionnaire.     

The Impact of a Science Education Game on Students’ Learning and Perception of Inhalants as Body Pollutants

This study investigated the knowledge gains and attitude shifts attributable to a unique online science education game, Uncommon Scents. The game was developed to teach middle school students about the biological consequences of exposure to toxic chemicals in an environmental science context, as well as the risks associated with abusing these chemicals as inhalants. Middle school students (n = 444) grades six through eight participated in the study consisting of a pre-test, three game-play sessions, and a delayed post-test. After playing the game, students demonstrated significant gains in science content knowledge, with game usability ratings emerging as the strongest predictor of post-test content knowledge scores. The intervention also resulted in a shift to more negative attitudes toward inhalants, with the most negative shift occurring among eighth grade students and post-test knowledge gains as the strongest predictor of attitude change across all grade levels. These findings suggest that the environmental science approach used in Uncommon Scents is an efficacious strategy for delivering both basic science content and influencing perceived harm relating to the inhalation of toxic chemicals from common household products.     

Cultural Perspectives on Student Behaviors： A Study of American and Chinese Students

To explore factors that influence the behavior of Chinese students and strategies for interventions, this paper presents a cross-cultural study on Chinese and American students. It examines the relationships between students＇ behaviors and the cultural influences; implications for special educators who work with minority students with emotional/behavioral disorders （E/BD） will also be discussed.

Students’ Reflections on Their Field Practicum: An Analysis of BSW Student Narratives

This qualitative study was undertaken to explore what undergraduate students reflect on during their learning to practice social work in the field. Reflection is essential in the social work field practicum where students learn the practice of social work by doing. Seventeen BSW students’ final field practicum learning papers are analyzed. Four themes emerge that highlight the content of their reflections: situations of uncertainty, opportunities for application, tensions in action, and confrontations with others. This article presents in detail these 4 themes. Discussion includes suggestions for helping students better engage in reflective learning.     

Effects of Problem-Based Learning on University Students’ Epistemological Beliefs About Physics and Physics Learning and Conceptual Understanding of Newtonian Mechanics

This study investigated the effects of problem-based learning on students’ beliefs about physics and physics learning and conceptual understanding of Newtonian mechanics. The study further examines the relationship between students’ beliefs about physics and their conceptual understanding of mechanics concepts. Participants were 124 Turkish university students (PBL = 55, traditional = 69) enrolled in a calculus-based introductory physics class. Students’ beliefs about physics and physics learning and their physics conceptual understanding were measured with the Colorado Learning Attitudes about Science Survey (CLASS) and the Force Concept Inventory (FCI), respectively. Repeated measures analysis of variance of how PBL influence beliefs and conceptual understanding were performed. The PBL group showed significantly higher conceptual learning gains in FCI than the traditional group. PBL approach showed no influence on students’ beliefs about physics; both groups displayed similar beliefs. A significant positive correlation was found between beliefs and conceptual understanding. Students with more expert-like beliefs at the beginning of the semester were more likely to obtain higher conceptual understanding scores at the end of the semester. Suggestions are presented regarding the implementation of the PBL approach.     

Development and Validation of an Instrument to Measure University Students’ Biotechnology Attitude

The impact of biotechnologies on peoples’ everyday lives continuously increases. Measuring young peoples’ attitudes toward biotechnologies is therefore very important and its results are useful not only for science curriculum developers and policy makers, but also for producers and distributors of genetically modified products. Despite of substantial number of instruments which focused on measuring student attitudes toward biotechnology, a majority of them were not rigorously validated. This study deals with the development and validation of an attitude questionnaire toward biotechnology. Detailed information on development and validation process of the instrument is provided. Data gathered from 326 university students provided evidence for the validity and reliability of the new instrument which consists of 28 attitude items on a five point likert type scale. It is believed that the instrument will serve as a valuable tool for both instructors and researchers in science education to assess students’ biotechnology attitudes.

Abstract

Based on the survey of “undergraduate family and educational background and freshman learning experience,” a statistical analysis of Guangzhou University first-year undergraduate students’ family backgrounds and participation in student organizational activities found a significant correlation between family background and the degree of student participation in such activities. A preliminary discussion of the findings is presented on the basis of cultural reproduction theory.     

Exploring Students’ Ideas About Risks and Benefits of Nuclear Power Using Risk Perception Theories

Due to increased energy demand, Turkey is continuing to explore the possibilities of introducing nuclear power. Gaining acceptance from local populations, however, may be problematic because nuclear power has a negative image and risk perceptions are complicated by a range of psychological and cultural factors. In this study, we explore the views about nuclear power of school students from three locations in Turkey, two of which have been proposed as sites suitable for nuclear power plants. About half of the student cohort believed that nuclear power can supply continuous and sufficient electricity, but approximately three quarters thought that nuclear power stations could harm organisms, including humans, living nearby. Rather few students realized that adoption of nuclear power would help to reduce global warming and thereby limit climate change; indeed, three quarters thought that nuclear power would make global warming worse. There was a tendency for more students from the location most likely to have a nuclear power plant to believe negative characteristics of nuclear power, and for fewer students to believe positive characteristics. Exploration of the possible nuclear power programmes by Turkey offers an educational opportunity to understand the risk perceptions of students that affect their decision-making processes.     

The Effects of a Chemistry Course with Integrated Information Communication Technologies on University Students’ Learning and Attitudes

The purpose of this study was to evaluate the instructional effects of using animations, static figures, PowerPoint bulletins, and e-plus software as chemistry texts with the aid of computer-based technology. This study analyzed the characteristics of students involved in three multimedia courses and their achievement and attitude toward chemistry and learning chemistry. The three samples included in this study involved 257 undergraduate engineering students enrolled in the courses during the academic year in which the study occurred. The results indicate that: (a) students acquired a better understanding of targeted chemistry concepts during the multimedia courses, (b) some categories of students, based on their major area of study, computer use, and attendance status at orientation achieved significantly (p < 0.05) higher post-test scores when adjusted for pre-test performance, and (c) significant differences and Cohen’s effect sizes in attitudes toward chemistry and learning chemistry were detected for students’ level of computer use, disposition toward computer multimedia, gender, and attendance at the multimedia orientation session. It appears to be helpful to incorporate computer-based multimedia (animations, images, sounds) teaching while utilizing constructivist design principles to facilitate students’ chemistry understanding and attitude toward chemistry and learning chemistry.     

University Students’ Knowledge Structures and Informal Reasoning on the Use of Genetically Modified Foods: Multidimensional Analyses

This study aims to provide insights into the role of learners’ knowledge structures about a socio-scientific issue (SSI) in their informal reasoning on the issue. A total of 42 non-science major university students’ knowledge structures and informal reasoning were assessed with multidimensional analyses. With both qualitative and quantitative analyses, this study revealed that those students with more extended and better-organized knowledge structures, as well as those who more frequently used higher-order information processing modes, were more oriented towards achieving a higher-level informal reasoning quality. The regression analyses further showed that the “richness” of the students’ knowledge structures explained 25 % of the variation in their rebuttal construction, an important indicator of reasoning quality, indicating the significance of the role of students’ sophisticated knowledge structure in SSI reasoning. Besides, this study also provides some initial evidence for the significant role of the “core” concept within one’s knowledge structure in one’s SSI reasoning. The findings in this study suggest that, in SSI-based instruction, science instructors should try to identify students’ core concepts within their prior knowledge regarding the SSI, and then they should try to guide students to construct and structure relevant concepts or ideas regarding the SSI based on their core concepts. Thus, students could obtain extended and well-organized knowledge structures, which would then help them achieve better learning transfer in dealing with SSIs.     

The Influence of Perceived Disgust on Students’ Motivation and Achievement

There are a wide range of student emotions in academic settings, but apart from emotions such as interest and well-being, disgust is a negative emotion which might be relevant in biology education, for instance, during dissection or when encountering living animals. This paper addresses the issue of situational disgust during a course at the university using living animals and prepared mounts. The course covers a wide range of organisms from protists (e.g. Paramecium) through invertebrates to vertebrates and uses many methods (e.g. microscopy, dissection, and behavioral observations) and specific content (anatomy, structure, and behavior). The dissection of the trout was rated as most disgusting, followed by working with living woodlice, living earthworms, and living snails. The least disgusting lessons were those dealing with microscopy, mammalian skulls, honeybee dance, and bird flight. Based on animals, macro-invertebrates were rated as most disgusting and mammals as least disgusting. Concerning methods, observing through a microscope was perceived as being least disgusting, followed by experiments without animals, then followed by experiments with living animals and, most disgusting, dissection. Disgust was correlated negatively with interest, well-being, and competence but positively with pressure and boredom. Thus, low disgust is related to high interest, well-being, and competence, while higher disgust is related to higher pressure and boredom. The results show a need for measuring situational disgust in addition to survey studies. They also suggest that perceived disgust negatively affects intrinsic motivation. This has implications for biology teaching, because carrying out dissections or experiencing living animals in the classroom may have a detrimental effect on motivation.     

Effects of Labels and Competence on Teachers’ Attributions for a Student

The extent to which special education teachers judged the mathematics performance of a fourth-grade youngster to be a function of his handicapping condition and/or his competence was evaluated. A videotape presentation and brief case study were reviewed and participating teachers were asked the extent to which various attributes were influential in the child’s performance. Differences were indicated for both labels and levels of competence. The results are discussed with regard to previous research and implications for reducing the effects of labels.     

Effects of Early Field Experience on Student Teachers’ Self-Concepts and Performance

This research was designed to determine whether (1) selecting a pre-student teaching field-based experience brought about significant differences in secondary student teachers’ self-concepts and performance; and (2) whether self-concept scores were predictors of performance ratings. Student teachers who had selected Project Interaction (PI) and those who had no early field experience (NF) were pre-and posttested on four self-concept variables, and rated on performance by cooperating teachers, supervisors, and by self-ratings. Pretest self-concept scores were correlated with performance ratings. Results indicated the PI group had significantly more conflict on the pretest, which was reversed on the posttest to produce a trend toward significantly less conflict. The PI group had significantly higher self-esteem than the NF group on the posttest. No significant differences were found on performance ratings, but cooperating teachers’ ratings did correlate with pretest self-concept scores. It was concluded that early field experience appeared to have latent positive effects on self-concept.     

Mexican-American Students’ Perceptions of Teachers’ Expectations: Do Perceptions Differ Depending on Student Achievement Levels?

This exploratory study examines the learning beliefs of high and low achieving, low-income Mexican-American students. Semi-structured interviews were conducted with 11 ninth grade students. The qualitative analysis shows that students’ perceptions of their teachers’ expectations of a “good” student or a “not so good” student did not differ along achievement lines. However, the students’ perceptions about what it means to be a good student differentiated the low-achievers from the high-achievers. This study’s findings may be used to inform educators about Mexican-American students’ orientation towards school and learning, in hopes for creating more equitable educational settings where all students achieve to their fullest potential.

Effects of Instructional Type and Feedback on Prospective Teachers’ Self-Efficacy Beliefs

Undergraduate teacher education students were randomly assigned to observe two types of instruction and two types of attributional feedback concerning teaching a child how to find the main idea of a paragraph. Dependent measures were the students’ self-efficacy beliefs regarding teaching the skill and their predicted persistence in teaching the skill. Two (cognitive modeling vs. direct instruction) by two (self-efficacy vs. task-oriented statements) ANOVAs revealed significant effects for cognitive modeling related to increases in self-efficacy beliefs and persistence levels, and for task-oriented statements in raising persistence levels. Implications for research in self-efficacy theory are discussed.
