The purpose of this exploratory study is to investigate students’ use and perceptions of online videos and intrinsic motivation toward the online videos in an organic chemistry laboratory course, which used online videos to assist students’ preparation and learning in the lab. Students’ responses to an anonymous survey showed that they watched the online videos one or more times based on their available time. Descriptive statistics showed that students had positive perceptions about the effect of online videos in terms of their preparation of labs, understanding the concepts, doing hands-on activities, and other aspects in the lab, which were consistent with their written comments. 44% of students showed positive intrinsic motivation toward the online videos according to items based on self-determination theory. Correlation results showed that the effect subscales were strongly related to each other, and students’ intrinsic motivation was significantly and positively related to students’ perceived effect of the online videos on their understanding and preparation with medium to large effect sizes. Inferential tests showed that students who had a positive perception of intrinsic motivation scored significantly higher on the understanding subscale with a medium to large effect size. The findings in this study suggest the online organic chemistry laboratory videos have significant potential to improve students learning and it is important to stimulate student intrinsic motivation toward the online videos which will help students benefits more from the effects of the online videos.

Grade Uncertainty

<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>

Ego Involvement

Competition is an apt place to experience intrinsic motivation, as competitive settings are often rich with optimal challenges and immediate, effectance-relevant feedback. Yet competition can also undermine intrinsic motivation and sustained engagement by introducing controlling pressures and negative feedback. To explain the contrasting effects of competitive settings on intrinsic motivation, this chapter presents a self-determination theory analysis. According to the theory, when elements of competitive settings are experienced as controlling or pressuring, they undermine competitors’ autonomy, decreasing intrinsic motivation. However, when these elements are perceived as both non-controlling and competence-informing, they can satisfy both autonomy and competence needs, enhancing intrinsic motivation. Unpacking these motivational crosscurrents, the authors identify the motivational implications of different elements of competition, including competitive set, pressure to win, feedback and competitive outcomes, challenge, leaders’ motivating styles, team interpersonal climate, and intrapersonal events such as ego-involvement. The authors also examine both positive and negative effects of competition on the need for relatedness. The chapter concludes by discussing how conditions that foster the need-satisfying aspects of competition not only enhance intrinsic motivation but also help prevent the emergence of competition’s darker sides, such as cheating, doping, objectifying opponents, aggression, and poor sportspersonship.

Contingency Perspective

Much of the work in public management indicates that public service motivation (PSM) generally leads to higher levels of organizational commitment. We argue that this relationship is more complex than generally assumed. First, drawing from self-determination theory, we propose that intrinsic motivation is conceptually distinct from PSM and that the two variables could interact. Second, drawing from the fit perspective, we further propose that ethical leadership is a contextual variable that will enhance the effect of PSM. A field study of public employees in Thailand provides support for this contingency perspective. We found that intrinsic motivation moderated the effect of PSM, such that the effect was positive only for individuals with high-intrinsic motivation but negative for those with low-intrinsic motivation. Furthermore, our analysis revealed a three-way interaction, which indicated that PSM was most positively related to organizational commitment when accompanied by high-intrinsic motivation and ethical leadership.
