AbstractAttrition is an important issue in higher education, especially in the field of computer science (CS). Here, we investigate to what extent an education reform affects the attrition of students by analyzing the pattern of grades of CS students’ academic achievement from 2010 to 2018 by IRT, based on Rasch-model analysis. We analyze data from 3673 undergraduate students of a large public university. In 2016 an education reform—as an intervention—was added to our BSc program: all theoretical lectures became compulsory to attend and we introduced a learning methodology course for all first-year students. According to our results, after the education reform most subjects became accomplishable, and students with lower levels of ability also tried to take exams. We succeeded in retaining 28% of our students. Analyzing students’ results could help administrators develop new programs in order to increase retention.

Purpose: Students entering university often lack knowledge about fats; whether students gain such information during four years at university is unclear. Students’ knowledge of fat in the first and fourth years was measured and compared. The effect of a nutrition course on knowledge was also examined. Methods: A total of 215 science students at a small undergraduate university completed a 15-item, closed-ended questionnaire concerning knowledge of fats in the diet. Results: Fourth-year science students have greater nutrition knowledge of fats than do first-year science students (p<0.005). Given that the majority of first-year students reside on campus and the majority of fourth-year students reside off campus, the purchasing of food and preparation of meals may explain the senior students’ greater knowledge of fat. Students who have taken a nutrition course know more about fats than do those who have not (p<0.001). Conclusions: Taking even one course in nutrition greatly increases nutrition knowledge. Universities could encourage undergraduate students to take a basic nutrition course, which should emphasize the identification and understanding of different types of dietary fats.

The study aimed to assess the prevalence of religious orientation, academic stress, and the use religion as a means to cope with academic stress among first-year undergraduates. The sample consisted of 321 first year students from five faculties of a religiously oriented public university in Malaysia. The data were collected using three separated instruments: a Religious Coping Questionnaire, an Academic Stress Scale, and an Orientation Scale. Frequency analysis was used to examine the prevalence of stress, and religious orientation, while Pearson moment correlation was used to analyze the relationship among the three main constructs: religious coping, religious orientation and academic stress. The analysis ran an independent sample t-test to check for gender-differences in academic stress, religious coping and academic stress. The results showed high incidences of the religious orientation and religious coping among the sample of undergraduates, but no significant gender differences. The study substantiated that one of the means by which the first year students reduced their academic stress is through religious coping and religious orientation.

Social perception is an evaluation process, which uses any information available &lrm;in order to form impressions, &lrm;understanding, and judgments about others. It is also &lrm;considered as an essential element of social skills. This study &lrm;aims to examine the psychometric analysis of students&rsquo; social perceptions of mathematics using Rasch model &lrm;analysis.&lrm; This study uses a quantitative survey approach. The sample comprised 40 first year students at King Faisal University&lrm;. The Rasch model is used because it is considered an effective tool for assessing constructs&rsquo; validity and reliability of the instrument. It also generalizes results and inferential studies. The developed questionnaire consists of six dimensions. Every dimension consists of six items. They are verifying the validity based on the Rasch model using item polarity, item fit, and dimensionality. In addition, the reliability was verified using person and item reliability, and item and person separation. The results of the Rasch model analysis show that the items of social perception of mathematics SPoM fit the model appropriately.

In this study, we report findings from the PCBuildAR project, in which students developed augmented reality (AR) artifacts following a guided design-based learning (DBL) approach. Sixty-two students participated in the study and were either in their first year to learn about computer science or were more experienced computer science students. In terms of learning performance, only the first-year students benefited from our guided DBL approach. In contrast, the experienced students were highly motivated to learn computer science not only immediately after the intervention, but also in the long term. For first-year students, this effect was only evident directly after the intervention. Overall, the guided DBL design proved to be effective for both motivation and learning, especially for younger students. For older learners, a better balance between guidance and autonomy is recommended.

A desired outcome of education reform efforts is for undergraduates to effectively integrate knowledge across disciplines in order to evaluate and address real-world issues. Yet there are few assessments designed to measure if and how students think interdisciplinarily. Here, a sample of science faculty were surveyed to understand how they currently assess students’ interdisciplinary science understanding. Results indicate that individual writing-intensive activities are the most frequently used assessment type (69%). To understand how writing assignments can accurately assess students’ ability to think interdisciplinarily, we used a preexisting rubric, designed to measure social science students’ interdisciplinary understanding, to assess writing assignments from 71 undergraduate science students. Semistructured interviews were conducted with 25 of those students to explore similarities and differences between assignment scores and verbal understanding of interdisciplinary science. Results suggest that certain constructs of the instrument did not fully capture this competency for our population, but instead, an interdisciplinary framework may be a better model to guide assessment development of interdisciplinary science. These data suggest that a new instrument designed through the lens of this model could more accurately characterize interdisciplinary science understanding for undergraduate students.

Objective: This study sought to better understand the research expectations of first-year students upon beginning university study, and how these expectations differed from those of their professors. Most academic librarians observe that the research expectations of these two groups differ considerably and being able to articulate where these differences are greatest may help us provided more focused instruction, and allow us to work more effectively with professors and student support services. Methods: 317 first-year undergraduate students and 75 professors at Mount Saint Vincent University in Halifax, NS were surveyed to determine what they each expected of first-year student research. Students were surveyed on the first day of term so as to best understand their research expectations as they transitioned from high school to university. Results: The gulf between student and professor research expectations was found to be considerable, especially in areas such as time required for reading and research, and the resources necessary to do research. While students rated their preparedness for university as high, they also had high expectations related to their ability to use non-academic sources. Not unexpectedly, the majority of professors believed that students are not prepared to do university-level research, they do not take enough responsibility for their own learning, they should use more academic research sources, and read twice as much as students believe they should. Conclusions: By better understanding differing research expectations, students can be guided very early in their studies about appropriate academic research practices, and librarians and professors can provide students with improved research instruction. Strategies for working with students, professors and the university community are discussed.

A Review of: Hulseberg, A., & Twait, M. (2016). Sophomores speaking: An exploratory study of student research practices. College & Undergraduate Libraries, 23(2), 130-150. http://dx.doi.org/10.1080/10691316.2014.981907 Abstract Objective – To understand sophomore undergraduate students’ research practices. Design – Mixed methods online survey and participant interviews. Setting – A small liberal arts college in the Midwestern United States of America. Subjects – The sample consisted of 660 second-year students; 139 students responded to the survey (21% response rate). In-depth interviews were conducted with 13 of the 139 survey respondents. Methods – A 13-item survey was emailed to sophomore students during October 2012. To analyze the results, the authors and a library student intern developed a coding scheme to apply to open-ended survey questions. Survey respondents could also volunteer for in-depth interviews. A total of 50 survey respondents volunteered, and 14 were invited for in-depth interviews between December 2012 and January 2013. The interview protocol included open-ended questions about students’ research experiences. Students were also asked to identify and discuss one recent research project. Interviews were audio and video recorded; data from one interview was lost due to technology failure, resulting in data analysis of 13 interviews. Interview transcripts were coded by an anthropology doctoral student, the study authors, and a library student assistant. Main Results – The survey found that students completed fewer research projects and used fewer library resources as sophomores than they did as first-year students. For example, only 4.9% (n=7) of students reported completing zero research assignments in their first year, compared with 34.5% (n=48) in their second year. When asked if there were library resources or skills they wanted to know about sooner in their academic career, students’ top reply was “Nothing” (34.5%, n=48), followed by “Navigating the physical space” (15.8%, n=22), “Librarians/staff & reference desk” (11.5%, n=16), and “Effective searching & evaluating sources” (10.8%, n=15). Male and female students’ responses differed, with male students less likely overall to express interest in library resources. While 42.4% (n=59) of students replied that they would consult with a librarian for help with their research projects, this option ranked third after professors (83.5%, n=116) and peers (70.5%, n=98). Again, responses varied by gender, with female students (49.5%, n=49) more likely than male students (26.3%, n=10) to contact a librarian about a research project. Most interview participants replied that searching online, including library resources, was their research starting point. Students most often selected research topics, based on their interest, from a professor-approved list. Students identified “relevant content, familiarity . . . , and credibility” (p. 138) as important source evaluation characteristics. The majority of students also used library information sources in their research, including databases, research guides, and the catalogue. Students most often mentioned struggling with “finding sources/identifying keywords” (n=6) and “finding known items” (n=6). Unlike survey respondents, interview participants unanimously reported consulting with a librarian. Most students (n=11) received library instruction as first-year students, and some suggested that this instruction helped them feel comfortable asking for help. Finally, most students felt that their research habits improved from their first year to their second year, specifically with regards to “their research technique, improved confidence . . . and an expanded source horizon” (p. 143). Conclusion – The authors recommend continuing strong information literacy support to first-year students, as well as working with faculty members and other campus partners to promote reference services to sophomores. When compared to previous research, the current study reports a higher percentage of students seeking librarian assistance; however, because some students also reported confusion about when and how to ask for help, further analysis could explore how reference librarians capitalize on peer and faculty “referral networks” (p. 145). Finding that students face significant challenges early in the research process was consistent with previous research, and future study might reveal more about this specific phenomenon in sophomores. Interviews should also be extended to include students who are non-library users. Finally, the authors suggest that the findings provide no evidence of a “sophomore information literacy slump” (p. 146).

Expressing an authoritative voice is an essential part of academic writing at university. However, the performance of the authorial self in writing is complex yet fundamental to academic success as a large part of academic assessment involves writing to the academy. More specifically, the performance of the authorial self can be complex for English as a Second Language (ESL) student-writers. This research investigated the extent to which ESL first-year students at the Fiji National University perform their authorial voice using interactional metadiscourse in their academic writing. The study employed a quantitative analysis of corpus produced by 16 Fijian ESL undergraduate students enrolled in an EAP course. The research found that the ESL authorial voice was predominantly expressed through boosters and attitude markers, with relatively little usage of other interactional metadiscoursal elements such as hedges, engagement markers and self-mentions. Further, the research showed that this particular cohort expressed their authorial voice and identity through boosted arguments and avoiding language that directly mentions the authorial self. The study concludes that the ESL authorial self for this cohort manifests itself in a selected range of selected interactional metadiscoursal elements, requiring the need to raise the awareness of self-reflective expressions for ESL students. The study also encourages further exploration of ESL authorial identity construction in academic writing at undergraduate level and beyond.
