The undergraduate chemistry laboratory is an ideal place for meaningful learning to occur, and the laboratory work is considered as an integral part of most chemistry courses; however, a significant proportion of laboratory experiments remain highly prescriptive and fail to challenge undergraduate students. This study investigated the chemistry laboratory environment among 170 undergraduate students at a private university in Beirut, Lebanon. Data were collected using the Chemistry Laboratory Environment Inventory with its both versions: Actual Chemistry Laboratory Environment Inventory and Preferred Chemistry Laboratory Environment Inventory. The findings of this study showed that the students prefer a chemistry learning environment with greater levels of integration and material environment, but less level of open-endedness. Suggestions for improving chemistry laboratory learning environments are provided. Keywords: Chemistry, laboratory, undergraduate courses, learning environment.

Students can perceive the laboratory environment in a variety of ways that can affect what they take away from the laboratory course. This qualitative study characterizes undergraduate students’ perspectives of a project-based Organic Chemistry laboratory using the theoretical framework of phenomenography. Eighteen participants were interviewed in a semi-structured format to collect their perspectives of the Organic Chemistry lab. Eight qualitatively different ways in which students perceived the lab were uncovered and an outcome space was derived. The findings of this work are intended to inform the design of the undergraduate laboratory curriculum in chemistry that facilitate better student learning. Implications and suggestions for design of laboratory courses based on the results of this work are also presented.

A series of quantitative studies investigated undergraduate students' perceptions of their cognitive and affective learning in the undergraduate chemistry laboratory. To explore these quantitative findings, a qualitative research protocol was developed to characterize student learning in the undergraduate chemistry laboratory. Students (N= 13) were observed and video recorded while performing one of their assigned laboratory experiments. Each student wore an action camera as well as a lapel microphone attached to a voice recorder to capture the experiment from the students' perspective. A tripod camera was also placed unobtrusively in the lab to record the student from a third person perspective. Students were interviewed within 48 hours of their video recording and asked to identify specific learning experiences in their laboratory experiment. The self-selected video episodes were shown to the students, and they were asked to describe what they were doing and why they were doing it. The students' descriptions were analyzed using Novak's theory of meaningful learning to characterize their cognitive and affective experiences. The self-identified learning experiences were dominated by descriptions of psychomotor learning with few students discussing cognitive experiences. The limited connections between cognitive and affective experiences revealed missed opportunities for meaningful learning.

The paper describes how to improve and evaluate learning outcomes in writing and critical thinking in the laboratory courses in the Bachelor program in Chemistry at the University of Bergen.  The suggested changes are based on research that show that these learning outcomes are improved when the students are involved in self-assessment, where they perform peer-review and are encouraged to reflect on their own learning experience. This process needs to be accompanied with systematic and frequent feedback.  It is also crucial to establish formal collegial groups where one can maintain systematic discussion regarding teaching in the laboratory courses. Suggested changes, and how they can be evaluated, are described in detail for two of the five mandatory laboratory courses in the program.

Experimental work supposes a unique opportunity to learn procedural contents. However, the conditions and constraints to learn procedures have not been sufficiently discussed or investigated in a laboratory environment. Students` difficulties in organic chemistry laboratory at university are described and explained. A case study (n=15 undergraduate students) was performed. The study was carried out in an actual laboratory class, using different ways for data gathering: 1) A comparison between declarative knowledge of students about experimental work and observations of procedures in class. 2) An evaluation of the effect of laboratory work on the knowledge of students related with the assembly of the apparatus. This research suggests that students’ difficulties in performing experimental work are deeply related to a deficient interrelationship between conceptual and methodological frameworks. Key words: experimental work, learning difficulties, organic chemistry laboratory, procedural contents, university.

This paper proposes a learning environment in which manual operations of school chemistry laboratory experiments, such as titration and aliquoting, are automated by means of computer controlled devices. The educational study focuses on characteristics of learning in the automated laboratory environment. Pilot teaching indicated that using automation devices significantly reduces the performance time of titration laboratory work. The students also noted that automated titration experiments are more simple and accurate. Therefore, automation of manual operations in laboratory practice has been found to provide a very positive learning environment.

In the era of digital learning, multimedia-based classroom has been commonly used in higher education including Malaysian higher education institutions. A case study has been performed to evaluate web-based learning using Level 1 to 3 of Kirkpatrick's model in a multi-disciplinary course at Multimedia University, Malaysia. In this study, mixed method research was employed in which triangulation was performed from multiple sources of data collection to give deeper understanding. Students perceived that learning with multimedia was enjoyable. They were also motivated in learning and engaged through the use of web module as multimedia was perceived to motivate them and make learning fun. Students showed significant improvements in their knowledge based on the pre-test and post-test results on learning evaluation. Students were perceived to transfer the learning from web-based learning into the learning outcome. The systematic evaluation can provide the feedback that educators and institution as a whole need to improve the learning environment and programme quality. This study contributes to the research field by adding another perspective in evaluations of web-based learning. It also provides empirical evidence on student perspectives, learning and behaviour in a private university. It demonstrated that the Kirkpatrick's model is useful as an evaluation tool to be used in higher education.

<p>Large, multi-section laboratory courses are particularly challenging when managing grading with as many as 35 teaching assistants (TAs). Traditional grading systems using point-based rubrics lead to significant variations in how individual TAs grade, which necessitates the use of curving across laboratory sections. Final grade uncertainty perpetuates student anxieties and disincentivizes a collaborative learning environment, so we adopted an alternative grading system, called specifications grading. In this system each student knows exactly what level of proficiency they must demonstrate to earn their desired course grade. Higher grades require demonstrating mastery of skills and content at defined higher levels. Each students’ grade is solely dependent on the work they produce rather than the performance of other students. We piloted specifications grading in the smaller, third quarter course of the lower division organic chemistry laboratory series held during a summer term. Open-ended questions were chosen to gather student and TA perceptions of the new grading system. TAs felt that the new grading system reduced the weekly grading time because it was less ambiguous. Responses from students about the nature of the grading system were mixed. Their perceptions indicate that initial buy-in and multiple reminders about the bigger picture of the grading system will be essential to the success of this grading system on a larger scale.</p>

Psychological wellbeing has gained much prominence over the recent years. Parallel to organizational domains, empirical attention is also being paid across the academics as well. The present study attempted to examine the much important role and relationship between academic press and student engagement and to what length academic psychological capital can potentially mediate in the relationship. A total of 371 undergraduate students were sampled for the present study from a private university in Bahrain. Through using structural equation modelling using Smart PLS 3 the results of the mediated model reported significant relationship between academic press and academic psychological capital (i-e academic efficacy and resilience). Though the study did not find any support for academic press and student engagement relationship, nonetheless, found a significant mediation of academic psychological capital in the relationship between academic press and student engagement. The findings have suggested that students’ perceptions about how much their teacher presses them to do thoughtful work, facilitation in explaining and motivating for full efforts can act as a key ingredient for nurturing students` connectivity with the studies in general and views about their own learning. Accordingly, the study has also underlined that students with positive academic press from their teachers tend to be higher in engagement due to enhanced efficacy and resilience. The present study has attempted to address a major research gap with acute empirical findings for academicians to enhance their students` wellbeing.
