Implementing the learning assistant model in European higher education

The learning assistant (LA) model is a widely used and researched model for institutional and course transformation towards research-based instructional strategies (RBIS). The LA model leverages learning assistants, pedagogically trained students, to facilitate student learning in active learning environments. However, although the LA model has shown significant results when implemented in university contexts in the United States, there has as yet been little documentation of similar implementation or results in European higher education. In this study, we present the results of a three-semester design-based research project to implement the LA Model in a Scandinavian physics department. The three core elements of the LA model (pedagogical training, course content meetings, and teaching in active learning environments) were implemented and iteratively refined, with necessary adjustments due to the specific institutional and cultural contexts documented. Throughout all three semesters, data was collected on how participation in the LA model affected LAs’ buy-in to RBIS using focus groups, pre/post surveys, and teaching observations. A thematic analysis of these data showed that participation in the LA model helped ensure LA buy-in to both the interactive engagement methods and goal of cultivating conceptual understanding that underlie most RBIS, and that the combination of teaching practice and pedagogical training seminars were key to this buy-in. We argue that these results demonstrate the potential usefulness of the LA model for creating institutional and cultural change in European higher education.

Can we teach students to think like scientists while learning science?

In the past 20 years the educational community has accumulated enough data to say with conviction thatinteractive engagement methods lead to better student learning gains than traditional transmission-modemethods (MICHAEL, 2006; FREEMAN et al., 2014). As MITCHELL WALDROP (2015) said “At this point itis unethical to teach in any other way.” But what is this way? There are many models of interactive engagement methods. One popular approach is the “flipped classroom” (FULTON, 2012). In the flipped classroom students read the textbook (or watch a video with the instructor explaining the material), then come to class and discuss what they read through answering questions posed by the instructor. They often work in pairs and participate in voting for the best answer. An example of a flipped classroom in physics education is the method of Peer Instruction (MAZUR, 1997). While the students in these classrooms work collaboratively answering questions and the professor limits lecturing to a minimum, the knowledge that students begin with comes from authority. Students get acquainted with physics concepts by reading the book or watching a video with an authority figure on the screen. While such methods lead to more learning than traditional lecturing, what message about physics are they sending to the students? One answer is that science is an area of study that can be learned by reading the book and discussing what you read in class. Is this the message we want our students to get from our science classes?

Prevalence and nature of computational instruction in undergraduate physics programs across the United States

A national survey of physics faculty was conducted to investigate the prevalence and nature of computational instruction in physics courses across the United States. 1246 faculty from 357 unique institutions responded to the survey. The results suggest that more faculty have some form of computational teaching experience than a decade ago, but it appears that this experience does not necessarily translate to computational instruction in undergraduate students' formal course work. Further, we find that formal programs in computational physics are absent from most departments. A majority of faculty do report using computation on homework and in projects, but few report using computation with interactive engagement methods in the classroom or on exams. Specific factors that underlie these results are the subject of future work, but we do find that there is a variation on the reported experience with computation and the highest degree that students can earn at the surveyed institutions.

Reaching More Students Through Thinking in Physics

Thinking in Physics (TIP) is a new curriculum that is more effective than commonly used interactive engagement methods for students who have the greatest difficulty learning physics. Research has shown a correlation between learning in physics and other factors, including scientific reasoning ability. The TIP curriculum addresses those factors. Features of the curriculum and evidence of its effectiveness are described. The most recent version of the TIP curriculum has greatly reduced a substantial gender gap that previously existed. More details and sample materials are provided in Thinking in Physics, a book intended for instructors of introductory physics, published in 2014 by Pearson as part of its Educational Innovation series. Additional materials, both for students and instructors, are provided on the website http://thinkinginphysics.com. Both the book and the website are free.

Exploring the Relationship Between Factors That Contribute to Interactive Engagement and Academic Performance

In an educational context, technology can prompt interactive engagement only when it is used in conjunction with interactive engagement methods. This study, therefore, examines the relationships between factors that contribute to higher levels of interactive engagement and performance, such as interactive engagement methods, technology, intrinsic motivation and deep learning. Five hundred and twenty-six (526) higher education students participated in this study. With structural equation modelling, the authors test the conceptual model and identify satisfactory model fit. The results indicate that interactive engagement methods, technology and intrinsic motivation have significant relationships with interactive engagement; deep learning mediates the relationships of the other variables with performance.

The impact of interactive engagement methods on students' academic achievement

Interactive engagement (IE) is a process that promotes students' conceptual understanding through activities, combined with immediate feedback from peers and/or instructors. The present study investigates the impact of IE on students' academic performance, using the comprehensive model of educational effectiveness. Engineering students (n = 158), randomly divided into three groups (self-assessment, collaborative learning, and control) provided the study data on questionnaires as well as with their test scores. Analyses of covariance reveal significant differences across groups, along with significant interaction effects. These findings have notable implications for improving students' academic achievement.

Impact of equity models and statistical measures on interpretations of educational reform

We present three models of equity and show how these, along with the statistical measures used to evaluate results, impact interpretation of equity in education reform. Equity can be defined and interpreted in many ways. Most equity education reform research strives to achieve equity by closing achievement gaps between groups. An example is given by the study by Lorenzo et al. that shows that interactive engagement methods lead to increased gender equity. In this paper, we reexamine the results of Lorenzo et al. through three models of equity. We find that interpretation of the results strongly depends on the model of equity chosen. Further, we argue that researchers must explicitly state their model of equity as well as use effect size measurements to promote clarity in education reform.

Assessing the Effectiveness of Computer Assisted Instructions in Physics at Undergraduate Level

Previous researchers have demonstrated significant improvement in students’ conceptual understanding of basic physics using interactive engagement methods of instruction. In this study, the effects of interactive computerbased simulations and animations investigated in classroom on students' conceptual understanding of electrostatics. Two groups – one control and one experimental of students at third year undergraduate level were studied to determine the role of computer simulations and animations in the development of functional understanding of the concepts of force, field, and potential in electrostatics. While few misconceptions persisted, the overall results indicate that students seem to have acquired a good general understanding of these concepts using such package. This occurred mainly in the area of verbal, vector and diagrammatic representation of the abstract physics concepts involved in the study.

Learning and retention of quantum concepts with different teaching methods

We measured mastery and retention of conceptual understanding of quantum mechanics in a modern physics course. This was studied for two equivalent cohorts of students taught with different pedagogical approaches using the Quantum Mechanics Conceptual Survey. We measured the impact of pedagogical approach both on the original conceptual learning and on long-term retention. The cohort of students who had a very highly rated traditional lecturer scored 19% lower than the equivalent cohort that was taught using interactive engagement methods. However, the amount of retention was very high for both cohorts, showing only a few percent decrease in scores when retested 6 and 18 months after completion of the course and with no exposure to the material in the interim period. This high level of retention is in striking contrast to the retention measured for more factual learning from university courses and argues for the value of emphasizing conceptual learning.

“Radio-Active” Learning: Visual Representation of Radioactive Decay Using Dice

The idea of using a dice game to simulate radioactive decay is not new.1 However, modern pedagogy encourages, if not requires, us to provide multiple representations and visualizations2 for our students. The advantage of interactive engagement methods also has been made clear.3 Here we describe a highly visual and interactive use of dice to develop student understanding of radioactive decay.

The New Studio format for instruction of introductory physics

We have developed the New Studio format of instruction for improved conceptual learning while retaining problem-solving skill development in large, first-year physics courses. This format retains the large lecture, but combines traditional recitation and laboratory instruction. The New Studio format integrates simplified laboratories with assigned homework problems to integrate conceptual and problem-solving skills. The studio format combines 2hours of lecture with 4hours of studio each week. The studio is taught for 2hours twice per week, and consists of up to 40 students working in groups of four at tables equipped with modern instructional technology and apparatus. The group setting allows for peer instruction and development of group skills. The combination of traditional lecture with the studio format enables a research-oriented physics department with a large service teaching load to implement research-based pedagogy. Student gains on the Force Concept Inventory were similar to other courses taught by interactive engagement methods.

Reducing the gender gap in the physics classroom

We investigate if the gender gap in conceptual understanding in an introductory university physics course can be reduced by using interactive engagement methods that promote in-class interaction, reduce competition, foster collaboration, and emphasize conceptual understanding. To this end we analyzed data from the introductory calculus-based physics course for non-majors at Harvard University taught traditionally or using different degrees of interactive engagement. Our results show that teaching with certain interactive strategies not only yields significantly increased understanding for both males and females, but also reduces the gender gap. In the most interactively taught courses, the pre-instruction gender gap was gone by the end of the semester.

Integrating Web-Based Teaching Tools into Large University Physics Courses

Teaching students in our large, introductory, calculus-based physics courses1 to be good problem-solvers is a difficult task. Not only must students be taught to understand and use the physics concepts in a problem, they must become adept at turning the physical quantities into symbolic variables, translating the problem into equations, and “turning the crank” on the mathematics to find both a closed-form solution and a numerical answer. Physics education research has shown that students' poor math skills and instructors' lack of pen-and-paper homework grading resources, two problems we face at our institution, can have a significant impact on problem-solving skill development.2–4 While Interactive Engagement methods appear to be the preferred mode of instruction,5 for practical reasons we have not been able to widely implement them. In this paper, we describe three Internet-based “teaching-while-quizzing” tools we have developed and how they have been integrated into our traditional lecture course in powerful but easy to incorporate ways.6 These are designed to remediate students' math deficiencies, automate homework grading, and guide study time toward problem solving. Our intent is for instructors who face similar obstacles to adopt these tools, which are available upon request.7

Using an online homework system enhances students’ learning of physics concepts in an introductory physics course

We report the results of a comparison of student understanding of physics concepts with and without online homework, as measured by the force concept inventory. We compared students in large introductory courses taught by interactive engagement and noninteractive engagement methods and with ungraded homework and with online homework. We also compared the understanding of students in different grade subgroups. The increase in the average force concept inventory normalized gain was statistically significant for all students taught with online homework, indicating that graded homework increases student understanding of physics concepts. The gain was significantly higher for those students taught with interactive engagement methods together with online homework. The C grade subgroup taught by interactive engagement methods benefited more from the implementation of online homework than the other subgroups.

Buzzwords and newspeak

You have to read beneath the lines in this business. Every week I get manuscripts filled with words and phrases fraught with cabalistic meaning. Would you believe, for instance, that in using the modeling method of teaching that the carefully structured development and concept flow would lead through Socratic dialogue to a rich classroom discourse? Perhaps it would help if I reminded you that a model is a primary unit of coherently structured knowledge. Of course, I am speaking only of the essence of models that are at the heart of modeling theory. These depend on student-centered teaching that is research-informed, leading to interactive engagement methods and cooperative learning.

Interactive-engagement versus traditional methods: A six-thousand-student survey of mechanics test data for introductory physics courses

A survey of pre/post-test data using the Halloun–Hestenes Mechanics Diagnostic test or more recent Force Concept Inventory is reported for 62 introductory physics courses enrolling a total number of students N=6542. A consistent analysis over diverse student populations in high schools, colleges, and universities is obtained if a rough measure of the average effectiveness of a course in promoting conceptual understanding is taken to be the average normalized gain 〈g〉. The latter is defined as the ratio of the actual average gain (%〈post〉−%〈pre〉) to the maximum possible average gain (100−%〈pre〉). Fourteen “traditional” (T) courses (N=2084) which made little or no use of interactive-engagement (IE) methods achieved an average gain 〈g〉T-ave=0.23±0.04 (std dev). In sharp contrast, 48 courses (N=4458) which made substantial use of IE methods achieved an average gain 〈g〉IE-ave=0.48±0.14 (std dev), almost two standard deviations of 〈g〉IE-ave above that of the traditional courses. Results for 30 (N=3259) of the above 62 courses on the problem-solving Mechanics Baseline test of Hestenes–Wells imply that IE strategies enhance problem-solving ability. The conceptual and problem-solving test results strongly suggest that the classroom use of IE methods can increase mechanics-course effectiveness well beyond that obtained in traditional practice.
