Assessment of learning gains associated with independent exam analysis in introductory biology

This study evaluates the impact of an independent postmidterm question analysis exercise on the ability of students to answer subsequent exam questions on the same topics. It was conducted in three sections (～400 students/section) of introductory biology. Graded midterms were returned electronically, and each student was assigned a subset of questions answered incorrectly by more than 40% of the class to analyze as homework. The majority of questions were at Bloom's application/analysis level; this exercise therefore emphasized learning at these higher levels of cognition. Students in each section answered final exam questions matched by topic to all homework questions, providing a within-class control group for each question. The percentage of students who correctly answered the matched final exam question was significantly higher (p < 0.05) in the Topic Analysis versus Control Analysis group for seven of 19 questions. We identified two factors that influenced activity effectiveness: 1) similarity in topic emphasis of the midterm-final exam question pair and 2) quality of the completed analysis homework. Our data suggest that this easy-to-implement exercise will be useful in large-enrollment classes to help students develop self-regulated learning skills. Additional strategies to help introductory students gain a broader understanding of topic areas are discussed.     

Students’ perceptions of Plickers and crossword puzzles in undergraduate studies

In higher education, there are calls to incorporate active learning experiences that place the student at the center of learning, rather than encouraging students to be passive listeners. For students to have a deeper and more meaningful learning experience, educators can use an active learning approach. This approach attempts to engage students at higher levels of thinking so that they are more interested in, better engaged with, and understand the course material better. The aim of this study was to investigate students’ perceptions of Plickers and crossword puzzles as low‐cost pedagogical tools to foster active learning in an undergraduate course in food science and technology. A mixed‐method survey consisting of a 5‐point Likert scale and open‐ended qualitative questions was administered via Blackboard to elicit student responses. A total of 121 students were enrolled for the course and 70.2% (n = 85) completed the survey. Plickers were found to be easy to use (mean = 4.66), provided opportunities to answer to formative questions anonymously (mean = 4.60), and helped increase participation in class (mean 4.05). The majority of students felt that crossword puzzles required them to think critically (mean = 4.53) and provided them with the opportunity to assess how well they understood the course content (mean = 4.45). Moreover, a statistically positive relationship was found between student collaborative learning and crossword puzzle implementation scores (r = .506, p < .01). The findings demonstrated that when implemented effectively, Plickers and crossword puzzles contributed to greater enhanced student engagement. These pedagogical tools can be applied as formative assessment instruments and offer a low‐cost alternative to the limitations encapsulated by didactic pedagogy.     

College students' ratings of student effort,student ability and teacher input as correlates of student performance on multiple-choice exams

In the class session following feedback regarding their scores on multiple-choice exams, undergraduate students in a large human development course rated the strength of possible contributors to their exam performance. Students rated items related to their personal effort in preparing for the exam (identified as student effort in the paper), their ability to perform well on the exams (identified as student ability), and teacher input that might have affected their exam performance. Students rated most student effort items higher than teacher input and student ability items. Notwithstanding, across all exams, ratings of student ability and teacher input correlated more strongly with exam performance than did student effort ratings. High and low performers on the exams differed significantly on ratings of student ability and teacher input, but were more similar on ratings of student effort.     

The effect of perceived class mean on the evaluation of instruction

A total of 232 college students in six different courses in three departments participated in a study to examine the effect of perceived course mean on course and instructor evaluations. Following a midsemester exam, students were given their actual earned exam scores and a manipulated class mean that was either ten percentage points higher or lower than the actual class average on the exam. Participants then completed an evaluation of the course and instructor. It was hypothesized that students scoring above the manipulated mean would rate the course and instructor more highly than students scoring below the manipulated mean. It was further hypothesized that students who were told that the class mean was higher would rate the course and instructor more highly than students who were told that the mean was lower. Results supported the first hypothesis. However, hypothesis two was not supported. Students receiving the lower manipulated class mean rated instructors more favorably. Results suggest the need to consider both individual exam scores and class averages in understanding the grade-teaching evaluation relationship.

Summer Conferences in Collegiate Mathematics

Courses in a wide variety of disciplines emphasize that what we think important, and are therefore likely to remember, is not the result of the objective situation but rather the result of our individual biases and interpretations. This article presents a classroom exercise that aids students in grasping the interpretive nature of historical accounts. Students in a history of psychology class and an Introduction to Human Services class (the control group) completed a questionnaire measuring the degree to which they view history as an interpretive enterprise versus a static one. In the psychology class, students then participated in an exercise that compared collective memories of a classroom event to emphasize the interpretive nature of personal history. Students in both classes completed the questionnaire a second time. Those students that completed the exercise scored higher on the follow-up questionnaire than did those in the control class. We discuss this exercise as a technique to aid students in grasping the importance of understanding the impact of individual perceptions of events.     

Using Scenarios as a Learning and Teaching Strategy with Students

This article describes and evaluates work undertaken as part of ATEE-RDC19, an exploration of using scenarios to enhance students' learning in teacher education. Action research was carried out with students who were following a module entitled National Curriculum and Beyond on an Education Studies degree. Students discussed and devised a scenario for 2020 and the need for the curriculum in schools to prepare students for life in the future. New curricula were devised to address the needs presented by the scenarios then justified, presented to and discussed with peers. Students completed questionnaires regarding their opinions of the use of this learning and teaching strategy. Students expressed their wholehearted approval for this kind of learning even though many had found the process difficult. They agreed that the use of scenarios had enabled them to widen their thinking about the curriculum and become more responsible for their own learning.     

A Search for Meaning

This article describes an active learning demonstration to increase student interest in and involvement with the topic of research ethics and deception. Students received false, low feedback on an exam and then completed a faculty evaluation form. The class was then informed about the deception and the research issue (the impact of grades on evaluations). Students then discussed their immediate reactions to the experience of deception. Two weeks later students wrote a reflective essay that described how their reactions and views had evolved. The discussion and essays indicated that the demonstration produced a high level of student involvement, empathy toward research participants, and self-examination.     

Causal attributions of students and student-proctors for performance on a university examination

Undergraduate psychology students rated the importance of several causes of examination outcomes both prior to and after taking a course exam. Similar attributions were made by advanced psychology students who served as course proctors. Students rated proctor characteristics as more important and their own characteristics as less important determinants of exam outcomes, particularly successful outcomes. Results suggested that positivity biases rather than egotism biases are operative in actual classroom settings. Further, contrary to expectancyconfirmation theory, student and proctor preexamination confidence was not strongly related to postexamination attributions.     

Identifying Key Features of Effective Active Learning: The Effects of Writing and Peer Discussion

We investigated some of the key features of effective active learning by comparing the outcomes of three different methods of implementing active-learning exercises in a majors introductory biology course. Students completed activities in one of three treatments: discussion, writing, and discussion + writing. Treatments were rotated weekly between three sections taught by three different instructors in a full factorial design. The data set was analyzed by generalized linear mixed-effect models with three independent variables: student aptitude, treatment, and instructor, and three dependent (assessment) variables: change in score on pre- and postactivity clicker questions, and coding scores on in-class writing and exam essays. All independent variables had significant effects on student performance for at least one of the dependent variables. Students with higher aptitude scored higher on all assessments. Student scores were higher on exam essay questions when the activity was implemented with a writing component compared with peer discussion only. There was a significant effect of instructor, with instructors showing different degrees of effectiveness with active-learning techniques. We suggest that individual writing should be implemented as part of active learning whenever possible and that instructors may need training and practice to become effective with active learning.     

Regulating interest when learning online: Potential motivation and performance trade-offs

Online learning may be particularly sensitive to self-regulatory trade-offs between maintaining interest and performance. Undergraduates in online or on-campus sections of the same course rated strategies used to motivate studying for the first exam, and interest after the first exam and at semester's end. First exam and final class grades were obtained. We compared online and on-campus students in reported use of strategies to enhance the importance of studying-related outcomes (goals-defined) and to enhance the studying experience (experience-defined). The latter included an Internet-based strategy (i.e., making studying more enjoyable by exploring class web page). Online and on-campus students did not differ in reported use of outcome-focused strategies but online students were more likely to report exploring the class web page. For online students, greater exploration was associated with higher interest but lower first exam grades, which predicted final interest and grades. Implications for regulating interest and online learning are discussed.     

First-year students’ appraisal of assessment tasks: implications for efficacy,engagement and performance

This study investigated students’ appraisals of assessment tasks and the impact of this on both their task-related efficacy and engagement and subsequent task performance. Two hundred and fifty-seven first-year students rated their experience of an assessment task (essay, oral presentation, laboratory report or exam) that they had previously completed. First-year students evaluated these assessment tasks in terms of two general factors: the motivational value of the task and its manageability. Students’ evaluations were consistent across a range of characteristics and level of academic achievement. Students’ evaluations of motivational value generally predict their engagement and their evaluations of task manageability generally predict their sense of task efficacy. Engagement was a significant predictor of task performance (viz. actual mark) for exam and laboratory report tasks but not for essay-based tasks. Findings are discussed in terms of the implications for assessment design and management.     

Undergraduate Students’ Preferences for Constructed Versus Multiple-Choice Assessment of Learning

Students (N = 161) in seven sections of an undergraduate educational psychology course rated ten performance-assessment options in collegiate courses. They rated in-class essay exams as their most preferred assessment and multiple-choice exams (in-class and out-of-class) as their least preferred. Also, student ratings of multiple papers and a term paper did not differ significantly from the rating for in-class essay exams. Overall, students preferred constructed forms of assessment over more objective assessment. With minor exceptions, student ratings of assessment preferences were generally consistent across gender and academic levels. In the main, student ratings of assessment options did not significantly correlate with exam performance in the course.     

Coordinating principles and examples through analogy and self-explanation

Research on expertise suggests that a critical aspect of expert understanding is knowledge of the relations between domain principles and problem features. We investigated two instructional pathways hypothesized to facilitate students’ learning of these relations when studying worked examples. The first path is through self-explaining how worked examples instantiate domain principles and the second is through analogical comparison of worked examples. We compared both of these pathways to a third instructional path where students read worked examples and solved practice problems. Students in an introductory physics class were randomly assigned to one of three worked example conditions (reading, self-explanation, or analogy) when learning about rotational kinematics and then completed a set of problem solving and conceptual tests that measured near, intermediate, and far transfer. Students in the reading and self-explanation groups performed better than the analogy group on near transfer problems solved during the learning activities. However, this problem solving advantage was short lived as all three groups performed similarly on two intermediate transfer problems given at test. On the far transfer test, the self-explanation and analogy groups performed better than the reading group. These results are consistent with the idea that self-explanation and analogical comparison can facilitate conceptual learning without decrements to problem solving skills relative to a more traditional type of instruction in a classroom setting.     

Teaching students how to study: a workshop on information processing and self-testing helps students learn

We implemented a "how to study" workshop for small groups of students (6-12) for N = 93 consenting students, randomly assigned from a large introductory biology class. The goal of this workshop was to teach students self-regulating techniques with visualization-based exercises as a foundation for learning and critical thinking in two areas: information processing and self-testing. During the workshop, students worked individually or in groups and received immediate feedback on their progress. Here, we describe two individual workshop exercises, report their immediate results, describe students' reactions (based on the workshop instructors' experience and student feedback), and report student performance on workshop-related questions on the final exam. Students rated the workshop activities highly and performed significantly better on workshop-related final exam questions than the control groups. This was the case for both lower- and higher-order thinking questions. Student achievement (i.e., grade point average) was significantly correlated with overall final exam performance but not with workshop outcomes. This long-term (10 wk) retention of a self-testing effect across question levels and student achievement is a promising endorsement for future large-scale implementation and further evaluation of this "how to study" workshop as a study support for introductory biology (and other science) students.

学习者的个体差异在外语学习过程中扮演着重要的角色。从相关的问卷调查结果来看,艺术类与非艺术类专业学生虽然在入学时根据高考成绩和摸底考试的分数被分到同一级别的班级里学习,但是经过近2年的学习,这两类学生的学习成绩和涉及学习策略的认知因素和包括动机和自我效能等在内的情感因素都表现出显著性差异。     

Project‐Based Learning Involving Sensory Panelists Improves Student Learning Outcomes

Project‐based, collaborative learning is an effective teaching method when compared to traditional cognitive learning. The purpose of this study was to assess student learning after the completion of a final meal project that involved a group of sensory panelists. A paper survey was conducted among 73 senior nutrition and dietetics students enrolling in Experimental Food Science, Spring 2013 and 2014. The survey comprised of qualitative and quantitative questions about students’ perceived learning outcomes. The project required students to prepare a 4‐course meal in 90 min, in groups of 4. Eighteen sensory panelists consisting of faculty and graduate students from the Nutrition, Dietetics, and Hospitality Management Department and administrative staff from the college evaluated the foods, asked students several food science‐related questions, and completed a survey about their involvement in the project. Students reported that this project reinforced class material (4.7 ± 0.6), and was enjoyable (4.6 ± 0.6) yet challenging (4.4 ± 0.7); numerous skills were developed, including team‐building (4.7 ± 0.5), food preparation (4.6 ± 0.5), and time management (4.4 ± 0.5). Students perceived that the involvement of sensory panelists was beneficial in terms of providing constructive feedback for improvement and motivating them to prepare high‐quality foods. It also prepared them for serving foods to individuals from different cultural backgrounds. However, some students found the experience stressful. For the sensory panelists, the project helped them to venture out of their areas of expertise. In conclusion, a meal project involving sensory panelists can result in positive learning outcomes.     

Student‐Generated Pre‐Exam Questions is an Effective Tool for Participatory Learning: A Case Study from Ecology of Waterborne Pathogens Course

This multiyear study helps elucidate how the instructional practice of student‐generated questions support learning in a blended classroom in science, technology, engineering, and mathematics subjects. Students designed multiple‐choice pre‐exam questions aimed at higher levels of learning, according to Bloom's taxonomy. Student‐generated questions were edited by the instructor and then discussed by the students in the classroom and in an online forum. We tested the hypothesis that this intervention improves student learning, measured as student achievement on the exam following the intervention, and compared to student achievement on the traditional exam (prior to which a review session focused on instructor‐led recitation of the key concepts). Following the intervention in all years, average grade on the post‐intervention exam increased by 7.44%. It is important to point out that not all students benefited equally from this activity. Students who were in the 4th quintile (60% to 80%) based on the results of the 1st exam demonstrated the highest achievement improving their performance on average by 12.37% percentage points (measured as a score on the 2nd exam). Gains were not observed in the semesters when the intervention was not implemented. In this study we provided students detailed instructions on how to design questions that focus on testing higher levels of learning.

The Synergistic Effects of Self-Regulation Tools and the Flipped Classroom

ABSTRACT

Students at open-enrollment institutions enter college with a wide range of academic preparedness and are often required to take developmental classes to increase their academic skills to be successful in higher education. Further, few students possess self-regulated learning skills to aid in their learning. Researchers posited that academically at-risk students benefit from gains in self-regulated learning skills when a modeling and scaffolding approach is used to implement self-regulated learning tools. Self-regulated skills coupled with an active learning environment like the flipped classroom provide positive synergistic effects for academically at-risk students. This study compared several iterations of the flipped classroom in a general chemistry class at an open-enrollment college where high school class rank and mathematics placement level varied significantly. The results of the multiple regression analysis indicated that mathematics level and class rank were significant when predicting overall course grade regardless of the learning environment. The results of a paired-samples t test did not reveal a significant difference upon addition of note-taking and exam wrappers in a flipped classroom learning environment. However, students graduating high school in the top third, middle third, and bottom third of their graduating class increased their overall course grades in a flipped classroom using self-regulated tools by 7%, 3%, and 6%, respectively. To enhance the quantitative results, the author provides student comments on note-taking and the use of exam wrappers.
