Teaching introductory modules and classes of undergraduate programmes can present a number of subjective and objective challenges. Objective challenges include a high degree of variation in students’ prior learning experiences combined with a high student-teacher ratio. Subjective challenges include the transitional changes which first year students undergo that include cognitive, affective and physiological changes as they make the leap from the often small and secluded secondary-level environment to the all-consuming tertiary-level environment. For introductory chemistry modules, such as General Chemistry, the pertinence of these challenges can have negative repercussions on students’ acquirement of basic chemical concepts in first year which could inherently go on to hinder their successful progression through their third-level education. In an effort to tackle the challenges posed against effective learning in General Chemistry modules, this exploratory research study set out to understand how the potential incorporation of a new approach to teaching and learning would be received by the three main cohorts involved. The attitudes and recommendations of undergraduate students, post-graduate students who have a role as laboratory demonstrators and module leaders towards the potential incorporation of Student-Inquiry activities and laboratories into General Chemistry were investigated. All three cohorts welcomed the incorporation of Student-Inquiry as part of the approach to teaching and learning. While the researchers and module leaders had an initial awareness of the challenges that come with teaching General Chemistry, little was known of the potential significance of the opportunity which lay amongst these challenges.

Abstract Objective The application of molecular graphics software as a simple and free alternative to molecular model sets for introductory-level chemistry learners is presented. Results Based on either Avogadro or IQmol, we proposed four sets of tasks for students, building basic molecular geometries, visualizing orbitals and densities, predicting polarity of molecules and matching 3D structures with bond-line structures. These topics are typically covered in general chemistry for first-year undergraduate students. Detailed step-by-step procedures are provided for all tasks for both programs so that instructors and students can adopt one of the two programs in their teaching and learning as an alternative to molecular model sets.

This article reports on and discusses the experience of a contrapuntal approach to teaching poetry, explored during 2016 and 2017 in a series of introductory poetry lectures in the English 1 course at the University of Johannesburg. Drawing together two poems—Warsan Shire’s “Home” and W.H. Auden’s “Refugee Blues”—in a week of teaching in each year provided an opportunity for a comparison that encouraged students’ observations on poetic voice, racial identity, transhistorical and transcultural human experience, trauma and empathy. It also provided an opportunity to reflect on teaching practice within the context of decoloniality and to acknowledge the need for ongoing change and review in relation to it. In describing the contrapuntal teaching and study of these poems, and the different methods employed in the respective years of teaching them, I tentatively suggest that canonical Western and contemporary postcolonial poems may reflect on each other in unique and transformative ways. I further posit that poets and poems that engage students may open the way into initially “less relevant” yet ultimately rewarding poems, while remaining important objects of study in themselves.

This study is directed to obtain information how peer feedback can improve students’ ability in writing. Specifically, it is directed to investigate whether peer feedback works and can improve students’ writing ability in writing sentences and narrative paragraphs, at the first year students of SMA Negeri 1 Balikpapan. The study was conducted based on the result of preliminary study at the school. It is found that the students’ ability in the language skills especially in writing is still insufficient. In the teaching and learning process the teacher provides fewer portions in writing activities for the students in class. In addition, the strategies used in the teaching and learning process are uninteresting because the students have to do the writing activities in under pressure. To answer the problems, a classroom action research is conducted. The teacher as a researcher works in planning the action, implementing the action, observing, and analyzing and reflecting the action. The subjects of the study are the second year students (X-IPA-1) of 2019/2020 academic year consisting of 40 students. The results shows that peer feedback obviously can improve the students’ ability in writing sentences and narrative paragraphs at the first year students of SMA Negeri 1 Balikpapan. It has been observed that the improvements are caused by the regular writing practice done by the students and the teacher’s response given to their writing. It becomes a sort of on going dialogue.

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).

In the Education context, the focus of Science, Technology and Society (STS) allows researchers with social, political and environmental nature themes, among others, which involve the active participation in the human being in face of society problems, in the sense of reflect, criticize and act. Therefore, the aim of this work was to develop conceptual and atheist learning based on the urban garbage theme in an intervention project with activities involving sustainability, reuse, consumerism and responsibilities. The research had a qualitative nature based on action research principles, developed by the pedagogy of projects, with the participation of thirteen (13) high school first year students from a public institution located in the city of Manaus-AM, the students were all volunteers. Data collection occurred through questionnaires, textual production, discussions and oral exposure and then they were qualitatively analyzed in an exploratory way. The results revealed that the students presented signs of conceptual understanding of the theme related terms, such as: garbage, solid waste, recycling and reuse, then sought to draw associations with chemical concepts and to propose environmental issues solutions using sustainability and social responsibilities. The students showed sensitivity regarding the theme and were willing to change their attitudes towards the problem.

The fast transition to fully online studies due to the pandemic made the universities around the world question many of their accepted notions on teaching foreign languages in general and English for Specific Purposes (ESP) methodology in particular. Putting stress on the synchronous remote teaching and learning has proven to yield a reductionist perspective missing asynchronicity, the dimension which makes reconsider the whole educational process. With its shift from the sole focus on learning terminology to training skills in authentic professional contexts, the task-based approach has long excelled in meeting the diverse needs of students. Thus, the research question is how well task-based teaching (TBT) solves the problems raised with asynchronous learning in a university ESP course. The research of available literature on TBT yielded the framework for constructing an extended task applicable in the advanced medical English. The case study with 120 first-year students of medicine organised around an informational interview with health professionals demonstrated easy adaptability of the task to the asynchronous nature of the educational process. Personal observations by the course instructor, summaries of student-conducted interviews, and student written feedback proved the responsiveness of the method to the learners’ needs and the potential of the approach in terms of motivation. The emphasis on self-directed learning, however, threatens the systematicity of the acquired language skills, as a more controlled teaching environment would not allow “skipping” any learning step. Additionally, TBT does not solve the problem of the voluminous teaching load.

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.

In this mixed methods study, we draw upon a systemic perspective to investigate the way that effective mathematics teaching is constructed in the ASPETE (School of Pedagogical and Technological Education) learning system. We focused on the perspectives of the first-year students (through questionnaires), of the lecturer who taught the course (through interviews), as well as of the research team (through observations). We considered both the pragmatic level (what they actually experienced) and the desired level (what they would prefer to experience). The results of the conducted analyses support the proposed research approach, revealing convergences and divergences in the mapped perspectives, which identify the mathematics teaching effectiveness of the subsystem of the mathematics class in ASPETE as an emergent, systemic phenomenon. The pedagogical implications are discussed, with respect to the planifications of teaching and learning mathematics in the ASPETE learning system.
