Cases of Science Professors’ Use of Nature of Science

Study provides qualitative analysis of data that answers the following research question: how college science faculty teach science and NOS and incorporate aspects of NOS and the history of science into their undergraduate courses? Study concentrates on four cases and more specifically on three introductory science classes and on four instructors who taught those courses. These instructors were chosen as case studies to explore in greater detail what occurs inside introductory science courses in one particular higher institution in the Northeastern United States. Participants’ teaching styles are presented through a combined and detailed presentation of interview data and classroom observations supported with examples from their classroom activities. Constant comparative approach was used in the process of organizing and analyzing data. Findings revealed that participants preferred to use the traditional teacher-centered lecturing as their teaching style and whose main concern was to cover more content, develop the problem solving skills of their students, and who wanted to teach the fundamental principles of their subjects without paying special importance to the NOS aspects. The study also revealed that other variables of teaching science, such as large class size, lack of management and organizational skills, teaching experience, and instructors’ concerns for students’ abilities and motivation are more important for these scientists then teaching for understanding of NOS.     

Course Format and Student Learning Styles: A Comparison of Political Science Courses

ABSTRACT

This study investigates whether differences in learning styles exist between students in online and face-to-face (FTF) sections of political science courses taught by three instructors. Some studies suggest that student preferences regarding online or FTF formats are influenced by their preferred modes of learning. Independent learners, for example, may prefer online courses since they provide individualistic opportunities to study outside of the traditional classroom. This study uses original survey data to assign students one of six learning styles in order to assess whether independent learners are more common in online courses. Our analysis finds no significant differences in independent learners when comparing the two formats. This finding runs counter to studies that argue that independent learners tend to prefer online courses. In fact, the only learning style where we observe a meaningful difference among online and FTF formats is among dependent learners. Contrary to expectation, students enrolled in online versions demonstrated a greater tendency toward dependent modes of learning. Further survey responses suggest that student lifestyle drove course format selection rather than learning style. These findings have important implications for universities that increasingly turn to online courses to address decreasing enrollments and attempt to remedy the high attrition rates associated with those courses.     

Analysis of Student–Instructor Interaction Patterns in Real-Time, Scientific Online Discourse

The characteristics of the online environment alter how students and instructors interact. Scientific discourse among students and instructors in an online text-only synchronous environment was analyzed. In converting dialogue to text, many of the nonverbal cues, such as facial expression and tone of voice, which instructors use to gauge student understanding are lost. The participants adapt their communication style to the medium, and we present a new interaction pattern for student–instructor communication found prevalent in the synchronous, text-only, online environment. This study has implications for instructors who use synchronous, text-based communication for their courses, namely the value of posing additional questions from the instructor to verify student understanding.     

The Force of Personality: Gottfried Keller's Educational Philosophy

We set out to identify the benefits and drawbacks of using more than one instructor to teach single section science courses at a large research university. Nine courses were investigated involving widely differing subjects and levels. Teaching models included: sequential teaching with two to six instructors each covering only their own modules, two teachers present in class at all times, and hybrids of these two models. A three-question survey was answered by 957 students and 17 instructors. Dominant advantages identified by both groups were variety of teaching style or perspectives and instructor expertise, with instructors being more likely to identify expertise as the primary advantage. Dominant disadvantages identified were adjustment to teaching style and expectations and confusion and communication issues. Data suggest that advantages are maximized and disadvantages minimized either in courses with two or more instructors interacting and collaborating in class or when special care is taken with coordination and collaboration if the course is sequentially taught. We conclude with specific recommendations to instructors and departments based on evidence from the data.     

Instructional Strategies to Help Online Students Learn: Feedback from Online Students

Increased enrollment in online programs and courses has prompted a plethora of research on instructional strategies that impact online students’ learning. Most of these strategies came from instructors, and others were solicited from students. While the literature notes that students who have more university experience tend to provide more substantive responses when solicited, there seems to be limited representation of online master’s students’ preferences on what instructional strategies work for them. There is paucity in the literature on how these preferred instructional strategies inform existing theoretical and practical frameworks that could impact online learning performance. This article discusses the Top Ten Instructional Strategies preferred by master’s students who responded to a dissertation survey question - What specific things would you like your online instructors do to help you learn successfully? - and relates these strategies to the Seven Principles for Good Practice in Undergraduate Education and the Quality Matters Rubric.     

INSTRUCTOR AND STUDENT ATTITUDES TOWARD DISTANCE LEARNING

Eleven community college instructors and the 334 students in their distance learning classes were surveyed. Data showed instructors had conflicting attitudes about distance education. They were willing to teach a distance learning class again, but they rated the quality of the courses as equal or lower quality than other classes taught on campus. Their students, on the other hand, were highly satisfied with these instructors and the courses . But the critical factor in much of traditional classroom instruction, direct interaction with instructors, played no role in determining students' satisfaction in these courses. This difference in the nature of student-teacher interaction in distance learning classes may explain instructors' conflicting attitudes.     

COMMUNITY COLLEGE STUDENT ATTRACTION TO AN ENGLISH COURSE: THE ASSOCIATIONS AMONG STUDENT GENDER,THE GENDER OF THE AUTHOR OF ASSIGNED READING,AND THE STYLE OF READING

This article reports the results of a factorial experiment that investigated the reactions of male and female students to a hypothetical English course offered at the community college level. The participants (N = 136) consisted of students enrolled in English 101 courses at four community colleges in a southeastern state. The independent variables were gender of the student, gender of the author assigned, and the type of reading assigned (narrative, expository). The dependent variable was a composite rating of student attraction to the English course. Females rated the course more favorably than males, and testing detected an interaction effect between gender of the student and the gender of the writer. Females preferred female authors, and males were attracted to male authors. There also was an interaction effect between gender of the author and style of writing. Participants preferred female authors and expository style. The findings have practical implications for educational programs, English instructors, and future research.

College Student Perceptions of The (In)Appropriateness and Functions of Teacher Disclosure

This study investigated college student perceptions of the (in)appropriateness of instructor disclosures and perceived functions of instructor disclosures. An interpretive analysis of 35 college students identified that family relationships, life experiences and background, and everyday talk and activities were forms of appropriate disclosures; whereas, intimate relationship details, personal problems, personal opinions, and drinking behavior were considered inappropriate topics for instructors to disclose. In terms of the function of instructor disclosures, students perceived that these disclosures worked to humanize instructors, make instructors approachable, and create affect for instructors and courses. Implications and future research are also discussed.     

Problems in Service Learning and Technical/Professional Writing: Incorporating the Perspective of Nonprofit Management

As service learning becomes a popular pedagogical approach to technical and professional writing courses, instructors need to examine critically the causes of practical problems that arise when classroom work involves nonprofit agencies. Nonprofit management theory provides a possible solution in its discussion of some basic characteristics of organizations in the nonprofit sector. By understanding these characteristics, instructors and students might anticipate and solve problems they encounter.

Collaborative Effort to Develop Middle School Preservice Teachers’ Mathematical Knowledge

Abstract

This article describes reflections of two mathematicians and a mathematics teacher educator who collaborated on the development and implementation of courses (probability and statistics connections, number concept connections, and middle school mathematics methods) for middle school mathematics preservice teachers. The instructors of the courses, two in mathematics and one in mathematics education, worked together to more explicitly link course materials, assignments, and the pedagogical approaches. Collectively, the courses were designed to address the five components of preservice teachers’ mathematical knowledge for teaching (PT-MKT), and to model effective teaching practices. Using their collective experiences co-planning and implementing these course adjustments were made in the subsequent year. The instructors were pleased by their implementation and student outcomes in all three courses.

We describe how each component of the PT-MKT framework was approached in these courses and discuss challenges experienced by the instructors, who were part of a larger effort to develop and implement a middle school teacher preparation program. The information shared is based on data collected as part of a program evaluation effort, and is bolstered by the instructors’ recollection of events. Overall, the instructors enhanced the curricula and their instructional practices and found that the attention placed on developing PT-MKT support the mathematical development of middle school mathematics preservice teachers.     

Who teaches mathematics content courses for prospective elementary teachers in the USA? Results of a second national survey

This article reports on a second national survey of higher education institutions in the USA to answer the question “Who teaches mathematics content courses for prospective elementary teachers, and what are these instructors’ academic and teaching backgrounds?” and addresses valuable information not collected with the first survey conducted in 2010. We surveyed 1740 institutions and a faculty member from each of 413 institutions (23.7%) participated in the survey. The survey results demonstrate that the majority of these institutions are not meeting the recommendations of the Conference Board of Mathematical Sciences (2012) and the Association of Mathematics Teacher Educators (2017) for prospective elementary teachers to take at least 12 semester-hour credits of mathematics content designed specifically for them. The data do indicate that there is movement toward more activity-based approaches for these courses as compared to the 2010 survey. Additionally, there is an increase in these courses having instructors with doctorates in mathematics education as well as an increase in instructors having grades 7–12 teaching experience. Most instructors for these courses do not have elementary teaching experience and have likely not had opportunities to think deeply about the important ideas in elementary mathematics. While most institutions still do not provide training and/or support for these instructors, formalized support and training appear to be increasing since the 2010 survey.

     

Characterization of human genetics courses for nonbiology majors in U.S. colleges and universities

We characterized college human genetics courses for nonscience majors (NSM) by 1) determining the number of U.S. institutions offering courses and the number of students taking them; and 2) surveying course instructors on course demographics, content, materials, and pedagogies. Between 2002 and 2004, an estimated 480 institutions of higher education (15.2%) offered a course: 8.4% of 1667 associate colleges, 16.1% of baccalaureate institutions, 25.3% of master's institutions, and 32.9% of doctoral institutions. This indicates a need to increase access to genetics education in 2-yr colleges. Based on instructor responses, approximately 32,000–37,000 students annually complete an NSM human genetics course out of approximately 1.9 million students earning a college degree each year (2.0%). Regarding course content, instructors consistently rated many concepts significantly higher in importance than the emphasis placed on those concepts in their courses. Although time could be a factor, instructors need guidance in the integration of the various concepts into their courses. Considering only 30.2% of the instructors were reportedly trained in genetics (another 25.4% in molecular and cellular biology) and the small fraction of students completing NSM human genetics courses, these results demonstrate the need for increasing the availability of these courses in undergraduate institutions of higher education, and particularly at 2-yr colleges.     

Design Features for Online Examination Software

Online education and computer‐assisted instruction (CAI) have existed for years, but few general tools exist to help instructors create and evaluate lessons. Are these tools sufficient? Specifically, what elements do instructors want to see in online testing tools? This study asked instructors from various disciplines to identify and evaluate the importance of several features that they want to see in testing tools. Along with standard elements, the respondents evaluated the importance of more advanced elements including adaptive responses and programmability, which would be used to add responsiveness and intelligence to provide more tailored questions and assistance. A latent variable analysis of the detailed model was performed and the results reveal that several advanced features not commonly available today would be useful to many instructors—particularly to handle higher level courses. Instructors teaching lower level courses tended to emphasize basic testing and simple grading features. The features were grouped into nine categories: question formats, feedback, programmability, grading, question bank, page display capabilities, platform, data analysis, and security. The results of the study examine the relative importance of the categories as well as the detail items within each category.     

Mind the gap: Enabling online faculty and instructional designers in mapping new models for quality online courses

Distance education has provided the foundation for new generations of learning, including courses delivered through various web-based educational technologies, also referred to as online learning. Many post-secondary institutions face the challenge of creating processes and systems to support instructors who are required to design, deliver, and frequently update online courses. Effective online course design prioritizes a student-centered pedagogical approach through active learning and meaning-making using modern technologies. This requires a wide spectrum of experience, technological skills, and pedagogical knowledge that is difficult to achieve. On one hand of the spectrum, are instructors with experience in online course delivery, learning technologies, and knowledge of online learning pedagogies. On the other hand of the spectrum, are instructors with insufficient experience, technological skills and awareness of online pedagogies. This disparity in instructors’ experiences, skills and knowledge results at times in a gap in ability. By providing a flexible and interactive model of support to instructors, instructional designers can shorten this gap in theoretical knowledge and practical skills. This paper explores the skill gap that some instructors face in the online learning domain and presents selected approaches to support instructors when transitioning to online courses based on the authors’ professional experiences. This paper considers two models of course design support from two unique higher educational institutions in the United States and in Canada, using different learning management systems. The results show that while these models have different contexts, they offer significant insights about common goals, flexible content, and learner-centered course design.     

Learning management system implementation: a case study in the Kyrgyz Republic

ABSTRACT

In this paper, the determinants of the intention to use online learning management system (LMS) among students in one of universities in the Kyrgyz Republic were studied, using quantitative and qualitative analysis. A total of 541 responses from students, enrolled in online courses during the fall and spring semesters 2016–2017, were used to examine students attitude toward online education. In addition, interviews with six instructors were conducted. Results showed that success of students in e-courses depend on year of education and the academic major of students. Factors, defined in the scope of this work, namely, technical characteristics of LMS, ease of use, feedback options of LMS and advantages of LMS use, were also found to be significant for students in their success in online courses. In interviews with instructors, three main points were highlighted, namely, problem with students’ perception of online courses, lack of online education experience among instructors and administrative issues.     

Distance Education

Abstract

Social work educators are increasingly using advanced information technologies in their distance education programs. Despite the widespread use of distance learning in social work education, there is limited information available regarding the effectiveness of courses, particularly practice courses, that use these technologies or the experiences of the students and instructors who are helping to pioneer these technological initiatives. This article presents reflections from students from two MSW practice classes linked together through interactive TV, also known as compressed video. The authors, who were course instructors using this technology, present their reflections on the process and make recommendations for future distance learning courses.     

Ratings of university teacher instruction: how much do student and course characteristics really matter?

Several student and course characteristics were examined in relation to student ratings of instruction. Students at a major Canadian university completed the Universal Student Ratings of Instruction instrument at the end of every course over a three‐year period, providing 371,131 student ratings. Analyses of between‐group differences indicate that students who attend class often and expect high grades provide high ratings of their instructors (p < .001). In addition, lab‐type courses receive higher ratings than lectures or tutorials, and courses in the social sciences receive higher ratings than courses in the natural sciences (p < .001). Regression analyses indicated, however, that student and course characteristics explain little variance in student ratings of their instructors (<7%). It is concluded that student ratings are more related to teaching instruction and behavior of the instructor than to these variables.     

Similarity of student ratings across instructors,courses, and time

This study raised three questions about the similarity or generalizability of student ratings of courses and instructors. First, how stable are student ratings of the same instructor giving the same course during twodifferent semesters? Second, how similar are student ratings of the same instructor in twodifferent courses? Third, how similar are student ratings of a given course being taught bydifferent instructors? Instances were identified in which student ratings on seven different factors were available for pairs of courses for each of these questions. For the case of the same instructor — same course—different semesters, student ratings were reasonably similar (median r for seven factors about 0.70). For the case of the same instructor—different courses, the median r was surprisingly low — about 0.40. For the case of the same course—different instructors, substantial correlations were obtained for some factors and insignificant correlations for other factors. Implications of these findings for practical use of student ratings and suggestions for further research in the area are discussed.
