Comparing the Rigor of Compressed Format Courses to Their Regular Semester Counterparts

This study compared workloads of undergraduate courses taught in 16-week and 8-week sessions. A statistically significant difference in workload was found between the two. Based on survey data from approximately 29,000 students, on average students spent about 17 minutes more per credit per week on 16-week courses than on similar 8-week courses. For selected general education courses taught in both formats, a similar result was obtained. When disaggregating results by subject and instructor, we found that the subject and the instructor of the course are more likely to be the cause of any significant difference in rigor based on workload.     

Impact of Adaptive Materials on Teachers and their Students with Visual Impairments in Secondary Science and Mathematics Classes

Science, technology, engineering, and mathematics (STEM) fields, important in today’s world, are underrepresented by students with disabilities. Students with visual impairments, although cognitively similar to sighted peers, face challenges as STEM subjects are often taught using visuals. They need alternative forms of access such as enlarged or audio‐converted text, tactile graphics, and involvement in hands‐on science. This project focused on increasing teacher awareness of and providing funds for the purchase of supplemental adaptive resources, supplies, and equipment. We examined attitude and instructional changes across the year of the programme in 15 science and mathematics teachers educating students with visual impairments. Positive changes were noted from pretest to posttest in student and teacher perspectives, and in teacher attitudes towards students with disabilities in STEM classes. Teachers also provided insights into their challenges and successes through a reflective narrative. Several adolescent students resisted accommodations to avoid appearing conspicuous to peers. Teachers implemented three strategies to address this: providing the adaptations to all students in the class; convincing the student of the need for adaptation; and involving the class in understanding and accepting the student’s impairment. A variety of teacher‐created adaptations for various science and mathematics labs are reported. Another finding was many adaptations provided for the student with visual impairment benefitted the entire class. This study supports the claim that given knowledgeable, supportive teachers, and with appropriate accommodations such as tactile or auditory materials, students with visual impairments can be as successful and engaged as other students in science and mathematics.     

Visual Instruction to Enhance Teaching of Technical Subject to Design Students

Visual instruction complementing verbal lectures is known to promote learning among students. In this study, the role of visual instruction in engaging learners effectively via the simplification of technical concepts was examined. Different aspects of visualisation, such as order of presenting and dimensionality, were tested to observe their effect on students’ approach to learning and learning outcomes. In this mixed‐method quasi‐non‐experimental explanatory study, visual instruction was applied in one of the undergraduate architecture modules that teaches fundamentals of building systems, which students often find difficult to comprehend. Three key variables, including spatial cognitive ability, approach to learning and learning outcomes, were measured using statistically valid instruments along with students’ feedback and interviews. These factors were also measured for the control group that did not receive visual instruction (n = 32), to assess the effect of the intervention. When taught with visualisation, students (n = 69), showed a significant increase in deep approach to learning (e.g., deep motive: t = 2.584, p = 0.011). In interviews, students expressed a deeper interest in the subject and reported that the topic was engaging in class. Visualisation favours students with a higher spatial ability and, thus, is useful for design students who receive spatial ability training in the course. Two‐dimensional visuals must be followed and preceded by three‐dimensional visuals to provide advanced organisation and the connection of new knowledge with known organisational models to be made.     

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.     

Validity of student self-reported ratings of learning

This study examined the relationship between individual student self-reported ratings of progress on relevant learning objectives and performance on exams administered during a college course. Across three sections of the same course taught by a single instructor, 188 students rated themselves at the end of the course on two objectives identified by the instructor as either essential or important. They also rated themselves on 10 other objectives the instructor identified as having minor or no importance. Self-ratings on course-relevant objectives correlated significantly and positively with four out of five exams and the course total, whereas ratings on irrelevant objectives did not. Students who rated their progress as either exceptional or substantial generally performed better on course examinations than those who rated their progress as moderate or less. These findings support the validity of student self-reported ratings of learning.     

Distance Learning: Relationships among Class Size,Instructor Location,Student Perceptions,and Performance

This study investigated differences in student perceptions and performance among three distance learning sites taking the same off-campus M.B.A. course with the same instructor, The sites varied in class size and instructor location. Two classes (one large and one small) were linked using a two-way video system with rotating origination. The third class was small and was taught in person each week. Data were collected over an entire semester. Class size influenced performance more than location of instructor. Performance in the two smaller classes was better than performance in the large class. Student characteristics and site variables accounted for over 50% of variance in performance. One interaction effect was found. Students with initial low perceived value did best when the instructor was physically present each week. For students with high initial perceived value, location of instructor did not matter.     

Variations of Normal Children

Previous research indicates that academic emotions are largely organized along domain-specific lines. In the present study (N = 1,687; Grades 8/11), the authors explored the domain specificity of academic emotions in terms of the moderating influence of having the same versus a different course instructor across domains. The authors evaluated discrete emotions consisting of enjoyment, pride, anxiety, anger, and boredom as experienced in the academic domains of mathematics and physics. Consistent with previous findings, between-domain relations for these emotions were relatively weak. These relations were, however, significantly stronger in classes having the same instructor in mathematics and physics compared with classes having different instructors for each subject. Nevertheless, the between-domain relations in classes having the same instructor were not strong enough to disconfirm the domain-specific conceptualization of academic emotions. Last, the authors discuss directions for future research on additional factors potentially affecting the strength of between-domain relations of academic emotions.     

Are Environmental Professors Unbalanced? Evidence From the Field

Most outcomes assessment in higher education has focused on content knowledge or skills development; however, attitudinal change is also a legitimate focus of assessment. We use the New Ecological Paradigm (NEP) to test whether courses designed to meet the same university environmental literacy requirement changed student environmental attitudes, and whether these changes resulted from instructor and/or course-content effects. We found student environmental attitudes did change significantly but in different directions depending upon who taught the course. The ability to measure such changes adds to the discussion in the environmental education community on the desired nature of attitudinal change and of the responsibilities of higher education instructors.     

Self-Regulated Strategy Development at Tier 2 for Second-Grade Students With Writing and Behavioral Difficulties: A Randomized Controlled Trial

Abstract

We examined the extent to which strategies instruction, using the Self-Regulated Strategy Development (SRSD) model, would enhance the writing, engagement during writing, and behavior of 44 second-grade students identified as having behavioral and writing difficulties. This study occurred within a comprehensive, integrated, three-tiered model of prevention that included behavioral, social, and academic components. Students were randomly assigned to an experimental or control condition. Students in the experimental condition received SRSD as a Tier 2 intervention. They were individually taught strategies for planning and composing, first for opinion essays and then for stories. Students met with their instructor 3 to 4 times per week for 30-min sessions, spending 3 to 4½ weeks in intervention for each genre. Students in the control group received the regular writing program. SRSD instructed students made significantly greater gains in writing quality and composition elements than control students for both opinion essays and stories. Students in the experimental condition also made greater gains than controls in academic engagement when writing opinion essays in their regular classroom. Transfer and behavioral effects, however, were limited. Implications are discussed.     

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.     

Does Reflective Journal Writing Improve Course Performance?

Abstract. This study investigated whether a reflective journal writing assignment would improve students' course performance. A total of 166 students from undergraduate sections of a course taught by the same instructor over three semesters completed the assignment as part of their requirements. Students (N = 317) from five previous semesters of the same course taught by the same instructor, who were not required to complete the assignment, served as a comparison group. Intervention and comparison groups were comparable on a variety of variables including all assignments, excepting the journal assignment. The findings are interpreted within the context of factors such as students' study habits and motivation.     

The interplay among environmental attitudes,pro-environmental behavior,social identity,and pro-environmental institutional climate. A longitudinal study

By using a panel design in a sample of 298 undergraduate/master students at an Italian public university, the present study aimed to test longitudinally the interplay among environmental attitudes, pro-environmental behavior, social identity, and pro-environmental institutional climate. The relationships were tested with cross-lagged analysis based on two waves over a 2-month period. The cross-lagged panel analysis revealed positive cross-lagged effects of social identity on environmental attitudes and pro-environmental institutional climate perceptions on social identity. Environmental attitudes and social identity at Time 1 did not predict Time 2 pro-environmental behavior. Pro-environmental behavior at Time 1 did not predict Time 2 environmental attitudes. Pro-environmental institutional climate perceptions at Time 1 did not predict Time 2 pro-environmental behavior. Finally, social identity at Time 1 did not predict Time 2 pro-environmental institutional climate perceptions.     

Two-way and one-way video: when is ‘no difference’ significant in distance education?

This study investigated the effects of instructor monitoring on student attitudes in an interactive television course. A comparison was made between learners located at sites with and without video feedback to the instructors. Data were collected for four variables: level of interaction as perceived by the student, value of the content taught, student assessment of gains in knowledge, and overall satisfaction. Multivariate analysis of variance (MANOVA) results indicated that student perceptions were not affected by the absence of video monitoring. The effect size was estimated to be practically zero and corroborated by the qualitative evidence collected in a subsequent study using interviews in other television (TV) courses. Findings were discussed in relation to instructional characteristics and system improvement priorities. The paper concluded that given appropriate instructional characteristics, partial absence of video feedback to the instructor may be adequately rectified to justify a wider coverage by interactive TV instruction even where real-time video feedback is not feasible.     

Sources of variance in end-of-course student evaluations

Abstract

Evaluation of college instructors often centers on course ratings; however, there is little evidence that these ratings only reflect teaching. The purpose of this study was to assess the relative importance of three facets of course ratings: instructor, course and occasion. We sampled 2,459 fully-crossed dyads from a large university where two instructors taught the same two courses at least twice in a 3-year period. Generalizability theory was used to estimate unconfounded variance components for instructor, course and occasion, as well as their interactions. Meta-analysis was used to summarize those estimates. Results indicated that a three-way interaction between instructor, course and occasion that includes measurement error accounted for the most variance in student ratings (24%), with instructor accounting for the second largest amount (22%). While instructor - and presumably teaching - accounted for substantial variance in student course ratings, factors other than instructor quality had a larger influence on student ratings.     

Explicit Instruction in Decoding Benefits Children High in Phonemic Awareness and Alphabet Knowledge

This article reports a study of 32 children who had been trained to a high level in phonemic awareness and alphabet knowledge over a 12-week period at preschool. During their first 6 weeks in kindergarten, these phonemically aware children were taught to read 10 real words, using either decoding and encoding techniques or a whole word method. At posttesting the children taught by the decoding and encoding method were superior in reading and writing both novel real words and pseudowords, compared to the whole word group. The results support the contention that explicit instruction in decoding is helpful even when children have high levels of phonemic awareness.     

The generalizability of student ratings of instructors: Item specificity and section effects

A number of recent studies have used generalizability theory to examine the dependability of student ratings of instruction. This study extends this line of research by examining the consistency of ratings between different sections of a course taught in a given semester by the same instructor, and by comparing the performance of global- and attribute-type instructor rating items. Five samples of physics instructors, varying in size from 5 to 12 instructors, were rated by their students on a form containing two global and eight attribute items. Each instructor taught two sections of a course. The study found that the section effect was small (ratings of instructors were consistent across different sections of the same course), and that the generalizability of ratings was substantially influenced by item specificity. For summary purposes, one global item seemed sufficient.     

The Effects of Videoconferencing,Class Size,and Learner Characteristics on Training Outcomes

ABSTRACT We examined direct and interaction effects of learners' characteristics (cognitive ability, prior knowledge, prior experience, and motivation to learn) and classroom characteristics (videoconferencing and class size) on learning from a 16-week course. A 2times2 quasi-experimental design varied the class size between large (∼60 students) and small (∼30 students) and between traditional classes with the instructor always present and classes taught using a videoconferencing system with the instructor present at each site every other week. Theory regarding instructor immediacy was used to predict that larger and videoconferenced classes would have negative effects on learner reactions and learning, but that highly motivated learners would overcome the negative effects on learning. Interactions between videoconferencing and motivation to learn, and class size and motivation to learn, were found in support of the theory. Research and practice implications are discussed.     

Student ratings and various instructional variables from a within-instructor perspective

The relationship between class size, instructional method, course level, reason for enrollment, and student ratings of instruction was assessed from a within-instructor perspective. Two hundred fifty-four pairs of courses taught by the same instructor were correspondingly identified and subjected to a stepwise multiple regression procedure. Only class size was found to be a significant predictor of ratings once individual differences between instructors were controlled, hence underlining the importance of (1) taking cognizance of the size of the course when using student ratings of instructors as a measure of teaching effectiveness, and (2) controlling for systematic variation due to instructor idiosyncracies in instructional research.     

Attitudes of high-school students taught using traditional and reform mathematics curricula in middle school: a retrospective analysis

This paper presents findings from a larger research project that provides insight into the attitudes of high-school students who were taught using different types of mathematics curricula when they were in middle school. A total of 44 12th-grade students from 10 high schools in the same urban school district were interviewed. Eighteen (41%) of them had been taught using a reform curriculum in middle school and 26 (59%) had been taught using a more traditional curriculum. Using Di Martino and Zan’s three-dimensional model for attitude, we found that the high-school seniors who had been taught using the reform curriculum in middle school harbored attitudes toward mathematics that differed significantly from the attitudes of those who had been taught using a traditional curriculum in middle school. Our analysis of the student interviews culled seven themes that provide fine-grained information about the students’ attitudes toward mathematics. Significantly greater percentages of reform students than traditional students had a relational Vision of mathematics as opposed to an instrumental Vision; however, there was no significant difference between the proportions of reform and traditional students who had a positive Emotional Disposition toward mathematics or a positive Perceived Competence in mathematics.
