Effect of prior knowledge and peer evaluation ratings on final exam performance in a team-based learning chemistry course.

INTRODUCTION: Various reports have been published regarding adoption of team-based learning (TBL) in pharmacy education. However, there is insufficient published evidence on the effect of student characteristics on student learning outcomes in a TBL curriculum. The purpose of this research was to evaluate the effects of pre-study examination results and peer evaluation ratings on learning outcomes. METHODS: The TBL strategy was adopted for a basic chemistry exercise for first-year students at a private pharmacy school in Japan (2012-2019). For the analysis, students were divided into four analytical groups according to quartiles of pre-study examination results. The students were further divided into the high-peer evaluation rating group and low-peer evaluation rating group. We compared the final exam performance results between these groups. RESULTS: In all four groups by quartiles of pre-study examination results, the course final exam performance was higher for the high-peer evaluation rating students than for the low-peer evaluation rating students. CONCLUSIONS: Within the TBL framework, students with higher peer evaluation scores performed better on the final exam, regardless of the pre-study examination results.

[Studies Using Text Mining on the Differences in Learning Effects between the KJ and World Café Method as Learning Strategies].

The KJ method (named for developer Jiro Kawakita; also known as affinity diagramming) is widely used in participatory learning as a means to collect and organize information. In addition, the World Café (WC) has recently become popular. However, differences in the information obtained using each method have not been studied comprehensively. To determine the appropriate information selection criteria, we analyzed differences in the information generated by the WC and KJ methods. Two groups engaged in sessions to collect and organize information using either the WC or KJ method and small group discussions were held to create "proposals to improve first-year education". Both groups answered two pre- and post- session questionnaires that asked for free descriptions. Key words were extracted from the results of the two questionnaires and categorized using text mining. In the responses to questionnaire 1, which was directly related to the session theme, a significant increase in the number of key words was observed in the WC group (p=0.0050, Fisher's exact test). However, there was no significant increase in the number of key words in the responses to questionnaire 2, which was not directly related to the session theme (p=0.8347, Fisher's exact test). In the KJ method, participants extracted the most notable issues and progressed to a detailed discussion, whereas in the WC method, various information and problems were spread among the participants. The choice between the WC and KJ method should be made to reflect the educational objective and desired direction of discussion.

[A self-improvement and participatory career development education program involving internships and volunteer training experience for pharmacy students: results verified in a follow-up survey three years after participation].

The Faculty of Pharmaceutical Sciences, Setsunan University, offers the Self-improvement and Participatory Career Development Education Program: Internship and Volunteer Training Experience for Pharmacy Students to third-year students. We previously reported that the training experience was effective in cultivating important attributes among students, such as a willingness to learn the aims of pharmacists, an awareness of their own role as healthcare workers, and a desire to reflect on their future careers and lives. A follow-up survey of the participants was carried out three years after the training experience. The questionnaire verified that the training experience affected attendance at subsequent lectures and course determination after graduation. We confirmed the relationship between the participants' degree of satisfaction with the training experience and increased motivation for attending subsequent lectures. Through the training experience, participants discovered future targets and subjects of study. In addition, they became more interested in subsequent classroom lessons and their future. The greater the participants' degree of satisfaction with their training experience, the more interest they took in practical training and future courses. The present study clarified that the training experience was effective in cultivating important attributes such as a willingness to learn and an interest in future courses. Moreover, the training positively affected the course determination after graduation.

[Practical chemistry education provided by team-based learning (TBL) and peer evaluation].

Learning chemistry is cumulative: basic knowledge and chemical calculation skills are required to gain understanding of higher content. However, we often suffer from students' lack of learning skills to acquire these concepts. One of the reasons is the lack of adequate training in the knowledge and skills of chemistry, and one of the reasons for this lack is the lack of adequate evaluation of training procedures and content. Team-based learning (TBL) is a strong method for providing training in the knowledge and skills of chemistry and reaffirms the knowledge and skills of students of various levels. In our faculty, TBL exercises are provided for first-year students concurrently with lectures in physical chemistry and analytical chemistry. In this study, we researched the adoption of a peer evaluation process for this participatory learning model. Questionnaires taken after TBL exercises in the previous year showed a positive response to TBL. Further, a questionnaire taken after TBL exercises in the spring semester of the current year also yielded a positive response not only to TBL but also to peer evaluation. In addition, a significant correlation was observed between the improvement of students' grades in chemistry classes and the feeling the percentage (20%) of peer evaluation in overall evaluation low (logistic regression analysis, p=0.022). On the basis of the findings, we argue that TBL provides a generic, practical learning environment including an effective focus on learning strategy and evaluation of knowledge, skills, and attitudes, and studies on the educational effects of TBL and peer evaluation.

[Adaptation of peer evaluation to small group discussion (SGD) and its validity for summative evaluation].

We adopted peer evaluation (mutual evaluation between students) for small group discussion (SGD) among first graders. The peer evaluation criteria were 5 grade scales for 5 fields: "preparation," "remark," "listening," "activeness," and "role." A comparison with tutor evaluation clarified the validity of peer evaluation for summative evaluation. Although the average of peer evaluation (4.2 (4.0-4.4)) was higher than that of tutor evaluation (3.8 (3.7-4.1)) (p=0.0601, Mann-Whitney U test), the value of the correlation coefficient between peer evaluation and summative evaluation of SGD (average 0.35 (0.12-0.54)) was almost the same as that of the coefficient between tutor evaluation and summative evaluation of SGD (average 0.36 (0.24-0.42)) (p=0.6761, Mann-Whitney U test). Principal component analysis showed that the tutor could not evaluate "remark" and "listening" independently, while students evaluate "listening" independently from other evaluation criteria. The combination of peer and tutor evaluation may be multilateral evaluation for SGD. The questionnaire about peer evaluation for students showed that they recognized the value of peer evaluation and favorably accepted its use.

Preparation of antibodies against a novel immunosuppressant, FTY720, and development of an enzyme immunoassay for FTY720.

FTY720 (1) is a novel immunosuppressant (immunomodulator), derived from ISP-I (2: myriocin and thermozymocidin). To clarify the pharmacokinetic properties of 1, antibodies against 1 were prepared and a competitive enzyme immunoassay (EIA) was developed. Two kinds of haptens, 3 and 4, for 1 were synthesized and coupled to ovalbumin (OVA). Rabbits were immunized with 3-OVA or 4-OVA, and corresponding antibodies were obtained. Both antibodies recognized the 2-amino-2-(2-phenylethyl)propane-1,3-diol moiety in 1. Using the anti-3-OVA antibody, a competitive EIA for 1 was developed and evaluated. The range of quantification by the EIA was 0.06-10 ng/mL. The application of the EIA has enabled us to measure the FTY720 concentration in serum after oral administration of 1 (1mg/kg) to rats.
