The Role of Teaching Assistants in Student-Centered Learning: Benefits, Costs, and Negotiations

As more faculty members utilize student-centered methods, we should also expect to see an increase in graduate teaching assistants (TAs) who are asked to co-teach these classes. However, little is written about the challenges TAs face and the adjustments they make when teaching student-centered courses. This study examined a student-centered course taught by the hevruta method, a dyadic approach that emphasizes text-based student discussions. Although students reported significant learning gains, both they and TAs had to negotiate new instructional roles. Based on student and TA feedback, strategies are presented to facilitate effective student learning in a student-centered course co-taught by TAs.     

A comparison between traditional and constructivist teaching in college biology

Two large sections of introductory biology for nonmajors were given the same course information with two different teaching styles. One group (N=86) was presented material in the traditional teacher-centered manner of lecture and laboratory while course information was given to the second group (N=98) in the student-centered, constructivist format. Learning was assessed in both groups with the same evaluative instruments and the results compared. This analysis revealed that the experimental (constructivist taught) population did significantly better than the control (traditionally taught) population. Furthermore, the students in the experimental group maintained a better attitude throughout the semester and enjoyed the introductory course more than the students in the control population.     

Assessment of the effectiveness of the studio format in introductory undergraduate biology

Kansas State University converted its introductory biology course, previously taught as an audio-tutorial (A-T), to a studio format in 1997. We share with others information about the process involved and present assessment data for the studio format course that address 1) student exam performance in A-T and studio; 2) student course grades in A-T and studio; 3) student and instructor perceptions and attitudes for A-T and studio; 4) student performance in subsequent biology courses for A-T and studio; and 5) gains in student learning for the studio course and other traditional lecture/lab courses. Collectively, these measures demonstrate that the studio format is as effective as or more effective (for some measures) than the A-T approach and traditional approaches in providing an effective learning environment. We discuss the issues involved in comparing course formats.     

The ability to understand and use conceptual change pedagogy as a function of prior content learning experience

This research examined the relationship between content instruction and the development of elementary teacher candidates' understanding of conceptual change pedagogy. Undergraduate students (n = 27) enrolled in two sections of a science methods course received content instruction through either traditional or conceptual change methods, followed by instruction about conceptual change pedagogy. Candidates were interviewed pre- and postinstruction about their content and pedagogical knowledge and also wrote conceptual change lessons. Twelve of the 27 subjects were videotaped teaching in the field. Results indicate that prior to instruction, most candidates had weak content knowledge and held traditional pedagogical conceptions. After instruction, students in the conceptual change group had significantly larger gains in their content knowledge than those in the traditional group, gave qualitatively stronger pedagogical responses, and used conceptual change strategies more consistently in practice. These results indicate that personal experience of learning science content through conceptual change methods facilitated the development of understanding and use of conceptual change pedagogy in teaching practice. Thus if conceptual change methods are to be incorporated into teacher candidates' repertoire, science content courses that students take prior to teacher education should be taught using conceptual change pedagogy. In addition, courses in science education should use pedagogy more in line with that taught in methods courses.     

Cooperative learning in industrial-sized biology classes

This study examined the impact of cooperative learning activities on student achievement and attitudes in large-enrollment (>250) introductory biology classes. We found that students taught using a cooperative learning approach showed greater improvement in their knowledge of course material compared with students taught using a traditional lecture format. In addition, students viewed cooperative learning activities highly favorably. These findings suggest that encouraging students to work in small groups and improving feedback between the instructor and the students can help to improve student outcomes even in very large classes. These results should be viewed cautiously, however, until this experiment can be replicated with additional faculty. Strategies for potentially improving the impact of cooperative learning on student achievement in large courses are discussed.     

New Books

ABSTRACT

How can we best support instructors to learn, practice, and retain student-centered, active-learning teaching strategies in their undergraduate courses? While approaches like professional development workshops may inspire some, permanent adoption of new pedagogy is rare. Here, we investigate “paired teaching” to achieve adoption and continued use of evidence-based practices. In this model, an instructor with little or no experience in student-centered teaching is paired with an experienced instructor in a semester-long course that has established student-centered pedagogy. This study evaluates information from eight pairs of instructors over a three-year period. Data was collected before, during, and after the paired teaching semester through interviews, written reflections, and teaching observations. Results indicate that paired teaching is beneficial as a professional development model for new instructors who have little teaching experience. The teaching practice of these instructors evolved to be increasingly student-centered, and they continued to use this pedagogy in subsequent classes. More established instructors who were less familiar with active learning showed lower tendencies to incorporate new pedagogies into their existing classes. We suggest best practices to maximize benefits and mitigate challenges associated with paired teaching.     

An Assessment of the Perception of Learning Gains of Freshmen Students in an Introductory Course in Nutrition and Food Science

ABSTRACT: The assessment of learning gains of students in science and other disciplines is becoming a reality following the gradual shift from the traditional style of teaching to a curriculum-based assessment of learning outcomes. The degree to which students perceive to have obtained the outcomes of a course can be measured through an assessment of students' learning gains. This study evaluated the perceived learning gains of freshmen students in an introductory class FSC 110-Introduction to Human Nutrition and Food Science (FSC 110)-over a 4-semester period. Students used the Assessment of Learning Gains Survey Instrument, developed by the Wisconsin Center for Education Research, to assess the level of their perceived learning gains. The data collected indicated that, overall, students favorably perceived their learning gains in the course. Through the instrument, students identified areas of the course that they perceived to have contributed positively to their learning experiences and those they perceived to have not contributed in any meaningful way to their learning experiences. The students' perception of their learning gains could be useful to the instructor because it offers opportunities to revise the course with respect to delivery method, assessment methods and tools, and course resources, and to improve individual support given to students to enhance their learning experience. Such alterations in pedagogy could lead to significant improvements in course quality, which could be archived and transferred to subsequent classes.     

Enhancing Student Performance Using Tablet Computers

Tablet PCs have the potential to change the dynamics of classroom interaction through wireless communication coupled with pen-based computing technology that is suited for analyzing and solving engineering problems. This study focuses on how tablet PCs and wireless technology can be used during classroom instruction to create an Interactive Learning Network (ILN) that is designed to enhance the instructor's ability to solicit active participation from all students during lectures, to conduct immediate and meaningful assessment of student learning, and to provide needed real-time feedback and assistance to maximize student learning. This interactive classroom environment is created using wireless tablet PCs and a software application, NetSupport School. Results from two separate controlled studies of the implementation of this model of teaching and learning in a sophomore-level Introductory Circuit Analysis course show a statistically significant positive impact on student performance. Additionally, results of student surveys show overwhelmingly positive student perception of the effects of this classroom environment on their learning experience. These results indicate that the interactive classroom environment developed using wireless tablet PCs has the potential to be a more effective teaching pedagogy in problem-solving intensive courses compared with traditional instructor-centered teaching environments.

The Use of E-Mail and In-Class Writing to Facilitate Student–Instructor Interaction in Large-Enrollment Traditional and Active Learning Classes

Student–instructor communication was examined in freshman biology classes taught either in traditional lecture style or by using a variety of student-centered, active learning approaches to engage students in the learning process (cooperative learning groups, wireless microphones, permanent name tags, in-class and out-of-class writing). In both classes students were encouraged to send questions, comments, and suggestions to the instructor via e-mail. In the active learning class, students also wrote in-class notes to the instructor. All messages could be classified as either content-related or procedural. More content-related messages were received in the active learning class than in the traditional class. Also, the percentage of students who sent content-related messages was much higher in the active learning class than in the traditional class. Finally, content-related messages from students in the active learning class were generally more thoughtful and insightful than those from students in the traditional class.     

Flipped-Class Pedagogy Enhances Student Metacognition and Collaborative-Learning Strategies in Higher Education But Effect Does Not Persist

In flipped-class pedagogy, students prepare themselves at home before lectures, often by watching short video clips of the course contents. The aim of this study was to investigate the effects of flipped classes on motivation and learning strategies in higher education using a controlled, pre- and posttest approach. The same students were followed in a traditional course and in a course in which flipped classes were substituted for part of the traditional lectures. On the basis of the validated Motivated Strategies for Learning Questionnaire (MSLQ), we found that flipped-class pedagogy enhanced the MSLQ components critical thinking, task value, and peer learning. However, the effects of flipped classes were not long-lasting. We therefore propose repeated use of flipped classes in a curriculum to make effects on metacognition and collaborative-learning strategies sustainable.     

Increasing Access with Intensive Hybridized Course Formats in a Community College Setting

This study compared the effectiveness of courses taught in a five-week intensive hybrid format with courses taught in an 11-week traditional classroom format in order to explore options for expanding access to higher education in a community college setting. Course effectiveness was measured quantitatively with student academic performance indicators, such as grades, pass rates, pretest/posttest results, and student perceptions of academic rigor. The study is unique in that it investigated course effectiveness when intensive and hybrid instructional delivery methods were combined into one format. Additionally, the study compared matched pair courses with the same instructors and coursework who taught each course in both the five-week intensive hybrid format and the 11-week traditional format, which controlled for instructor influence on student learning. The historical rationale behind community colleges and contemporary initiatives to expand them have underscored the need to increase access by providing a range of options to higher education that meet the varying needs of students. The comparison found that the five-week hybrid course format was academically equivalent to the 11-week traditional format. The study indicates that course delivery combining hybrid and intensive instructional delivery can be academically effective and, therefore, has the potential to improve access in a community college setting.     

Performance and perception in the flipped classroom

Changes in the conceptualisation of higher education have led to instructional methods that embrace technology as a teaching medium. These changes have led to the flipped classroom phenomenon - where content is delivered outside class, through media such as video and podcast, and engagement with the content, through problem-solving and/or group work, occurs in class. Studies investigating the impact of the flipped classroom have mainly looked at the student experience with little focus on whether exam outcomes are enhanced by flipping. An undergraduate Material Technology course at The University of the West Indies was taught in two formats over two successive years. The course was taught during the 2012/13 academic year in a ‘traditional’ format but, after reflecting on student feedback and personal pedagogy, the lecturer restructured the class and taught it in a flipped format during the 2013/14 academic year. This research examines whether the flipped format improved the learning experience in relation to exam performance and student perception. Data was gathered through analysis of course grades and student evaluation questionnaires. The lecturer’s reflective comments were also reviewed before and after the study. Analysis of the qualitative data shows that the flipped format led to a slight improvement in how students perceived the course and the lecturer’s reflection shows that they are keen to continue with the flipped format as it allowed more time for them to work with students at an individual level. While no significant change in relation to average cohort exam performance was found, fewer students in the flipped classroom achieved marks at the highest level. It is therefore recommended that practitioners who intend to flip their classroom pay as much attention to student performance as they do to student perception.     

Teachers as co-designers of technology-rich learning activities for early literacy

Although kindergarten teachers often struggle with implementing technology, they are rarely involved in co-designing technology-rich learning activities. This study involved teachers in the co-design of technology-rich learning activities and sought to explore implementation and pupil learning outcomes. A case-study method was used to investigate: the co-design experiences of seven teachers; implementation in three kindergarten classes; and pupil learning outcomes. Interviews were used to study teacher perceptions about pedagogy, technology, early literacy, co-designer role, practicality and co-ownership. Process notes were made during design team meetings. Observations were made of implementation, and pupil learning was pre- and post-tested in non-equivalent control quasi-experimental design (N = 111). Findings indicate that teacher perceptions about pedagogy affect their co-design involvement. The extent of integration of on- and off-computer activities was similar between teachers. Significant pupil learning gains were found, thus indicating that the co-designed activities had positive effects on pupil learning outcomes.     

Affective Learning in Online Multimedia and Lecture Versions of an Introductory Computing Course

This study evaluated students' affective learning in an introductory computing course that was taught in Hong Kong once in a lecture format and twice in a rich interactive multimedia online format to 414 college students in all. A simplified experience sampling method was used to assess affective learning at the midterm and end of each course in terms of intrinsic engagement (positive affect, perceived challenges, perceived skills in course activities), extrinsic engagement (performance expectations, performance goals, performance self‐efficacy), and negative affect in course activities. Controlling for students' computing background and pre‐enrollment academic ability, multivariate analysis of covariance indicated that, compared to lectures, e‐learning modules fostered more intrinsic engagement, comparable extrinsic engagement, and more negative affect. Findings suggest directions for developing online courses that optimise both cognitive learning and affective learning.     

Learn before lecture: A strategy that improves learning outcomes in a large introductory biology class

Actively engaging students in lecture has been shown to increase learning gains. To create time for active learning without displacing content we used two strategies for introducing material before class in a large introductory biology course. Four to five slides from 2007/8 were removed from each of three lectures in 2009 and the information introduced in preclass worksheets or narrated PowerPoint videos. In class, time created by shifting lecture material to learn before lecture (LBL) assignments was used to engage students in application of their new knowledge. Learning was evaluated by comparing student performance in 2009 versus 2007/8 on LBL-related question pairs, matched by level and format. The percentage of students who correctly answered five of six LBL-related exam questions was significantly higher (p < 0.001) in 2009 versus 2007/8. The mean increase in performance was 21% across the six LBL-related questions compared with <3% on all non-LBL exam questions. The worksheet and video LBL formats were equally effective based on a cross-over experimental design. These results demonstrate that LBLs combined with interactive exercises can be implemented incrementally and result in significant increases in learning gains in large introductory biology classes.     

Investigating Strategies for Pre-Class Content Learning in a Flipped Classroom

In a flipped classroom model, learning of basic content is shifted before class while in-class time is used for concept application. Empirical and controlled research studies are lacking on the best strategies to provide the necessary pre-class content instruction. In this study, we tested three methods of pre-class content learning—interactive online tutorials, video lectures, and textbook-style readings—while holding the content and the in-class application activities constant. Identical introductory, non-majors biology classes were manipulated at both a public, open-enrollment institution and a private, highly selective institution. We found that video lectures offer a small advantage to overall student learning over interactive tutorials or textbook-style readings. Although our two populations differed in their ability to effectively learn from pre-class activities, through a student-centered flipped classroom approach, students at both institutions demonstrated equal learning gains by the final assessment. Potential reasons for some observed differences are suggested.     

The One-minute Paper as a Catalyst for Change in Online Pedagogy

ABSTRACT

Online/virtual educators face challenges related not only to technology and pedagogy, but also to student assessment, which remains a critical function to reinforce. Brief assessment tools can be used by the instructor to tailor the learning experience, and where appropriate, to reinforce student-centered learning. In this qualitative study, we explored the use of a one-minute paper as a brief and consistent assessment tool in master’s level social work courses in research and advanced clinical practice with individuals courses. The coded segments of qualitative responses (# of coded segments n = 728) from 52 students were examined to explore common themes from the student’s experience. Discussion is offered on the use of this tool for brief and consistent assessment of knowledge gains in class, as well as the impact these themes may have for the intentional pedagogy for the facilitation of learning.     

Flipped Active Learning in Your Mathematics Classroom Without Videos

We explored the effectiveness of a flipped active learning pedagogy in a liberal arts mathematics course without video or interactive preparation. In both control and active learning classes, students were required to respond to a reading before class and take a quiz after class. During the active learning class, students worked together in groups on problems instead of listening to a lecture. This modest change in the in-class course structure showed that students were more willing to work with peers and ask questions of the instructor. Sources examined include common grade items as well as pre- and post-course attitude surveys.     

Teacher-as-Researcher Reform: Student Achievement and Perceptions of Learning Environment

This study reports the results of a research project conducted as part of high school teachers' efforts to bring about reform of science education in their school. Two classes of Grade 8 students (N = 43) taught by the same teacher were monitored in terms of students' perceptions of their learning environment, achievement levels, and conceptual understanding of research. Quantitative methods (questionnaire, tests and examinations, GPA) and qualitative methods (interviews, videotaped lessons, artifacts) were combined while the learning environment was changed to a student-centered open inquiry format. Not unexpectedly, relationships between the Autonomy and Student-Centeredness scales of the Constructivist Learning Environment Survey (CLES) and immediate (unit test) and delays post-tests (examination subsection) were detected. On the other hand, although student-student interactions in small-groups and whole-class sessions were a significant part of the learning environment, the Negotiation scale was not related to achievement. Three case studies of representative students (in terms of achievement and perceptions of the learning environment) are featured, further underscoring the importance of monitoring reform of teaching at the classroom level.
