The effects of testing on science process skill achievement

The purpose of this study was to examine the effects of testing on the achievement of students using self-instructional materials to learn science process skills. In one section of an undergraduate science method class, students were paced through a programmed textbook and were given short quizzes in class after each of the process skill lessons was assigned, while in another section, students worked at their own pace and were held responsible for completing the lessons by the end of the semester. Students taking the quizzes throughout the semester were expected to attain a higher level of process skill proficiency because previous studies have shown that taking a test immediately after learning leads to better retention of the material. Results indicated that taking frequent quizzes did not differentially affect process skill acquisition.     

Creating a Science E-book with Fifth Grade Students

This article explains how one teacher used iBooks Author, a free digital textbook creation tool that makes iBooks for iPads, in an upper elementary classroom to improve students’ expository writing skills and understanding of science content. The classroom teacher taught students pre-requisite writing and technology skills for two weeks, and then helped these students design, develop, and publish their own iBook. Students planned and developed content using Thinking Maps, storyboards, Google Docs, iMovie and other technology tools to create their iBook. A comparison of students’ work in the iBook to previous written work revealed an improvement in expository writing in multiple ways: better organization and connection of ideas; increased use of academic vocabulary; and an increased use of clarifying details and analogies. Students also gained a deeper understanding of science concepts as reported through their comments after the project was finished. Students became more proficient users of the technology, and also reported an increased sense of self-efficacy and confidence because they published a book in the iBookstore

Enhancing student learning of research methods through the use of undergraduate teaching assistants

By using a quasi-experimental design, in this study, we test the effect of undergraduate teaching assistants on student learning. Data were collected from 170 students enrolled in four sections of a quantitative research methods course, two sections without undergraduate teaching assistants and two sections with undergraduate teaching assistants, over two semesters. Results indicate that having undergraduate teaching assistants in the classroom can result in higher student performance. Students in the sections with undergraduate teaching assistants earned higher grades, were more likely to pass the course with a C or higher and performed better on half of the student learning outcomes than students in the sections without an undergraduate teaching assistant. Based on the overwhelmingly positive results on student learning, we would recommend the active use of undergraduate teaching assistants in the classroom, but especially for courses that students find challenging.     

The effects of teacher read-alouds and student silent reading on predominantly bilingual high school seniors’ learning and retention of social studies content

Teacher read-alouds (TRA) are common in middle and high school content area classes. Because the practice of reading the textbook out loud to students is often used out of concern about students’ ability to understand and learn from text when reading silently (SR), this randomized controlled trial was designed to experimentally manipulate text reading while blocking on all other instructional elements to determine the relative effects on learning content. Predominantly Spanish–English bilingual twelfth-graders (n = 123) were randomly assigned to either a TRA or SR condition and provided 1 week of high quality instruction in US history. Daily lessons included teaching key terms in the passage, previewing text headings, and conducting comprehension checks. Results of immediate, 1-week delayed, and 1-month delayed assessments of content learning revealed no significant differences between the two groups. Students were also asked to rate the method of reading they believed best helped them understand and remember information. Students in the SR condition more consistently agreed that reading silently was beneficial. Findings suggest low performing adolescents of different linguistic backgrounds can learn content as well when reading appropriately challenging text silently as when the teacher reads the text aloud to them.     

Does the Arrangement of Embedded Text Versus Linked Text in Homework Systems Make a Difference in Students Impressions,Attitudes, and Perceived Learning?

Students in a first-semester general chemistry course at a large southwestern university completed a 3-week homework assignment using MindTap, a Cengage Learning product. MindTap is the first major electronic system that has homework questions embedded in the text, such that students read a short section of the textbook and then answer a question set. Prior to MindTap, electronic homework systems were stand-alone or contained questions with links to the textbook. Next, students completed two 2-week homework assignments in Online Web Learning (OWL) version 1 also from Cengage Learning. The OWL system shows homework questions with a link to the textbook in a separate window. Both the MindTap and OWL systems contain the same or similar questions. After the students used both homework systems, a survey was given that included Likert-scaled and open-response questions that dealt with students’ perceived level of understanding using the different systems, how easy the systems were to use, and the advantages/disadvantages of each system. A delayed survey was given at the end of the second semester of general chemistry, during which students had used OWL for the complete semester. This paper investigates the effects of the arrangement (embedded vs. linked) on student preferences and perceived learning in this pilot study with a 300-person class. Based on the results of the study, it was found that students perceived that they learn more with MindTap and prefer the embedded text in MindTap over the linked text in OWL.     

Support of the collaborative inquiry learning process: influence of support on task and team regulation

Regulation of the learning process is an important condition for efficient and effective learning. In collaborative learning, students have to regulate their collaborative activities (team regulation) next to the regulation of their own learning process focused on the task at hand (task regulation). In this study, we investigate how support of collaborative inquiry learning can influence the use of regulative activities of students. Furthermore, we explore the possible relations between task regulation, team regulation and learning results. This study involves tenth-grade students who worked in pairs in a collaborative inquiry learning environment that was based on a computer simulation, Collisions, developed in the program SimQuest. Students of the same team worked on two different computers and communicated through chat. Chat logs of students from three different conditions are compared. Students in the first condition did not receive any support at all (Control condition). In the second condition, students received an instruction in effective communication, the RIDE rules (RIDE condition). In the third condition, students were, in addition to receiving the RIDE rules instruction, supported by the Collaborative Hypothesis Tool (CHT), which helped the students with formulating hypotheses together (CHT condition). The results show that students overall used more team regulation than task regulation. In the RIDE condition and the CHT condition, students regulated their team activities most often. Moreover, in the CHT condition the regulation of team activities was positively related to the learning results. We can conclude that different measures of support can enhance the use of team regulative activities, which in turn can lead to better learning results.     

A Guided Problem‐Based Learning (PBL) Approach: Impact on Critical Thinking

The impact of the Guided Problem Based Learning (Guided PBL) approach on Critical Thinking (CT) skills in a core business analysis course was examined. The implementation of this approach included using a textbook created for this purpose, which presents problems first, with blank spaces for students to work them out. Discussion of the concepts and theory needed to understand and solve the problems, as well as the solutions, come later in the book. This book is referred to as the Reversed Textbook. Students attempt to answer questions or solve problems in class with instructor guidance as needed, before discussion of theory. Student learning in sections taught prior to implementing the Guided PBL method was compared with student learning in sections taught with the method. Results indicate that the approach motivated learning and improved student performance on a departmental final exam by an average of 9%. When measured on CT questions alone, the improvement was on average 24%. Finally, the Guided PBL approach also improved group task performance by 6%. All the improvements were statistically significant.     

Exploring student study behaviours in engineering: how undergraduates prepared textbook problems for online submission

ABSTRACT

While textbooks serve as a primary source of content material and problem-solving practice for undergraduates in engineering, studies that investigate how engineering students prepare assignments based on textbook problems are limited. To examine how engineering students complete textbook-based assignments outside of class, this exploratory qualitative study retrospectively investigated the study behaviours of six undergraduates enrolled in a required, second-year undergraduate engineering course at a mid-size, public university in the western United States. Within the course, students solved textbook problems and electronically submitted problem answers for graded credit. Findings from in-depth, semi-structured interviews showed that students identified and used a variety of non-traditional and unsupported resources in personalised approaches to preparing assignments. Resource choice and use was affected by students’ preferences for timely support, convenience, and social connections. The online submission process seemed to influence students’ adoption of study behaviours and resources considered less effective for deep, conceptual learning.     

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.     

Learning With Dynamic Geometry Programs: Perspectives of Teachers and Learners

Abstract

In this exploratory phenomenological study, part of a larger mixed-design research project, the authors examined teacher and student roles in, and reactions to, a student-centered instructional geometry program using the Geometer's Sketchpad. Grade 7 students worked for 2 weeks in their regularly scheduled mathematics class on activities that allowed them to explain on-screen relationships among geometric shapes. A companion computer-based instructional tutorial was available as an accessible resource. The class sessions and specific dyads were observed, students surveyed, and teacher and selected students interviewed. Findings centered on 2 overarching themes: issues of power and learning. The teacher had difficulty relinquishing control of the learning environment even though she had agreed to do so. Students, however, liked their new freedom, worked hard, and expressed greater interest in the subject material.     

Beyond the Given: Stretching Mathematical Thinking Through Journaling

This paper reflects on a teaching experiment and presents details of a pedagogical technique where students periodically write down their clearest interpretation of the conditions imposed on various discrete mathematical subjects they are learning in class. Through iterations, students generate a more complete understanding of the material, one that they themselves can justify. This experiment was conducted in the Discrete Mathematical Structures course; as it contains several subtopics, each of which uses a discrete set of elements with specific conditions. The textbook does not mention how those conditions are effectively put to use, and often uses the natural numbers as the default domain. Students are required to identify in their journals the exact properties that the elements need to have, justify how they are being put to use, and in ambitious cases attempt to sharpen them if possible. This activity can be adapted to different contexts and is not specific to the topic of Discrete Mathematical Structures.     

Ways students read texts

College students responding to the Preferred Method of Study (PMOS) questionnaire explained how they approach reading a new textbook chapter for comprehension. Results indicated that a significant positive correlation exists between the number of passes a student makes at new textbook material and his/her college grade-point average. Women showed a significant preference for adopting a single method of study. Less than half of the students queried construct “organizational tools” such as outlines or diagrams as they study a textbook. Students said they would alter their textbook strategies in response to the type of test they expected significantly more often than they would for the type of subject matter being studied. Only 6% of the students said they make a conscious effort to link the new concepts in the text to prior knowledge. There was no discernable relationship between the study strategies undergraduate college students employ and their college grade level (freshman through senior).     

Using Biomedically Relevant Multimedia Content in an Introductory Physics Course for Life Science and Pre-health Students

We will describe a one-quarter pilot algebra-based introductory physics course for pre-health and life science majors. The course features videos with biomedical experts and cogent biomedically inspired physics content. The materials were used in a flipped classroom as well as an all-online environment where students interacted with multimedia materials online and prior to engaging in classroom activities. Pre-lecture questions on both the medical content covered in the video media and the physics concepts in the written material were designed to engage students and probe their understanding of physics. The course featured group discussion and peer-lead instruction. Following in-class instruction, students engaged with homework assignments which explore the connections of physics and the medical field in a quantitative manner. Course surveys showed a positive response by the vast majority of students. Students largely indicated that the course helped them to make a connection between physics and the biomedical field. The biomedical focus and different course format were seen as an improvement to previous traditional physics instruction.     

Using Q-methodology to determine students' perceptions of interprofessional anatomy education

Interprofessional education (IPE) prepares healthcare students for collaboration in their future careers. The purpose of this study was to determine which aspects of the IPE Program in Anatomy at McMaster University contributed to the development of healthcare student's interprofessional skills. Q-methodology was used to identify the students' common viewpoints of the IPE experience. A total of 26/28 (93%) of students in the course from the medical, nursing, midwifery, physician assistant, occupational therapy, and physiotherapy programs participated in this study. Students were asked to sort a Q-sample of 43 statements about the IPE dissection course derived from previous qualitative studies of the program. Using the centroid factor extraction and varimax rotation, three salient factors (groups) emerged, namely: (1) Anatomy IPE Enthusiasts, (2) Practical IPE Advocates, and (3) Skeptical IPE Anatomists. The Anatomy IPE Enthusiasts believed that students from different disciplines brought unique anatomical knowledge and each group member guided others through difficult material. The Practical IPE Advocates expressed that they would be stronger advocates for interprofessional teams in the future because of the course. The Skeptical IPE Anatomists strongly disagreed that learning with students from different disciplines helped them gain an understanding of their roles in the context of other healthcare professionals and felt that there was little benefit from the IPE program compared to other non-interprofessional programs. These findings about student attitudes are critical to drive an evidence-based evolution of the IPE dissection course, since students' perceptions can have a profound influence on interprofessional collaboration in the workplace.     

Grades,learning, and student evaluation of instruction

In the first experiment, the author employed three different grading standards, identified as stringent, moderate, and lenient, in separate sections of the course Psychology of Learning. Other aspects of the course were the same for each section. The different grading standards resulted in substantially different grade distributions in the anticipated direction. Evaluations of both the instructor's performance and the couse decreased as the stringency of the grading criteria increased. Every item on the evaluation questionnaire was systematically influenced by the grading criteria. The amount learned, as measured by performance on the objective part of the final test, increased as the stringency of the grading criteria increased. In the second experiment, the subjects were the students in two sections of the course Introductory Psychology, taught by the author during the same term. The same textbook, course notes, and grading criteria were employed. The manipulated variable was test frequency, with the two sections receiving either weekly or biweekly tests. Students in the section receiving weekly tests scored 11.9% higher, on the average, over all tests. This resulted in a substantial difference in grade distributions. The ratings of the section receiving lower grades were substantially lower on every item of the rating form. Students appear to rate instructors on the basis of a global impression (liking) which they form, which is strongly influenced by the grade the student receives.     

The Efficacy of Retesting in Relation to Improved Test Performance of College Undergraduates

Abstract

A causal-comparative analysis was done of the test performance of undergraduate students in five different sections of educational psychology taught over a 3-year period. A pretest-posttest design was used to test the hypothesis that a testing program employing fewer retests than original tests produced significant gains in mean highest test/retest scores. Original tests and retests were of comparable mean difficulty, discrimination, and cognitive level. Correlations between the unretested means and highest test/retest means for retesters in the five sections were statistically significant. Various retesting programs were not found to be significantly different in producing gains in mean test scores among retesters. Subgroup analysis revealed that retesting was used most frequently by students at the lower end of the marking spectrum. Further subgroup analysis revealed no significant difference in the frequency of retesting among sophomores, juniors, and seniors in the five sections. Students’ response to the use of retests was overwhelmingly positive.     

Fostering students’ evaluation behaviour while searching the internet

A program for teaching 9th graders course content (history) and how they should evaluate information found on the WWW was designed and tested. Goal of the program was to teach content, evaluations skills, and to achieve transfer of these skills to a different domain. In the design of the program the principles of two transfer theories were combined using a design-based research approach. Results revealed that the program improved students’ evaluation behaviour. Compared to the students of the control condition, the evaluation skills of students in the experimental condition improved to a higher level, but did not lead to transfer. Students in the experimental classes scored higher on the final content exam than students in the control class.     

Effects of thematic‐based,hands‐on science teaching versus a textbook approach for students with disabilities

Institutions of higher education, states, and local K–12 districts have been challenged to improve math and science education for our nation's students. In the past few years, there has been renewed interest in inquiry‐based, activity‐oriented instruction in science for students with disabilities. Yet, there still exists the need for further empirical evidence to support instructional improvements for students with more involved emotional and behavioral disabilities. This study describes a program in which 18 middle school students with serious emotional disturbances were instructed, over the course of 8 weeks, on “Matter” by two different instructional approaches. Students in one classroom received a traditional textbook approach to science content, whereas students in another classroom received science instruction by a hands‐on, thematic approach. Over the course of instruction, data were collected regarding students' behavior and achievement. Results indicate that, overall, students in the hands‐on instructional program performed significantly better than the students in the textbook program on two of three measures of science achievement, a hands‐on assessment and a short‐answer test. The students did not differ on a multiple‐choice format test. With regard to behavior, there were no significant differences in behavioral problems found between the two groups of students over the course of the study. Findings are discussed in relation to instructional implications for students with disabilities in the science classroom. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 245–263, 2005     

If you build it will they come?; Exploring the student perspective of weekly student evaluations of teaching

This exploratory study investigated the students’ use of formative, weekly, online evaluations of teaching through a virtual learning environment. Results were based on in‐depth interviews of seven students at a rural university college in the UK. Students from different genders, education levels and backgrounds volunteered for the study. The students thought it was a good tool and useful for providing anonymous feedback. However, their motivation to fill in the evaluations every week varied throughout the period of study, and the weekly feedback soon became routine and too onerous a task, and thus had a tendency towards being superficially conducted. Students were more inclined to comment on negative issues, rather than critically analyse positive ones. They also tended to be more positive towards conducting the evaluation if the lecturer discussed them and/or made changes to their future lectures.
