Conceptual understanding of acids and bases concepts and motivation to learn chemistry

The purpose of this study was to investigate the effect of 5E learning cycle model oriented instruction (LCMI) on 11th-grade students' conceptual understanding of acids and bases concepts and student motivation to learn chemistry. The study, which lasted for 7 weeks, involved two groups: An experimental group (LCMI) and a control group (the traditional teacher-centered instruction [TTCI]). Based on multivariate analysis of covariance results, the LCMI students outperformed the TTCI students in terms of conceptual understanding about acids and bases. Similarly, the students from the experimental group scored higher motivation and this difference was found to be statistically significant. These findings demonstrated that instruction based on learning cycle model provide students a deeper conceptual understanding, foster high-order thinking, engage them in the learning process, and influence their motivation to learn by increasing the relevance of school chemistry to their daily lives.     

Interactive lectures in engineering education

This article discusses an alternative approach to lecturing: the interactive lecture. In the literature, interactive teaching is forwarded as a means to increase the effectiveness of lectures. Members of lecturing staff still seem, however, reluctant to incorporate interactive teaching in their classes,as interaction reduces the time they can devote to explaining subject matter. Lecturers often voice the concern that they will not get enough material across in interactive lectures and that this consequently will negatively affect student learning. In order to establish whether or not the concerns of lecturers could be empirically verified, an experimental study was conducted. This study examined the effects of interactive teaching in lectures, using an interactive voting system and peer instruction, on: the attainment of learning objectives; student motivation; and student perception of the instruction offered. From the results a complex picture emerges. Results suggest that students may learn as much in interactive lectures compared with traditional lectures, but a traditional lecture may also result in active student involvement. The study indicated that interactive teaching will not automatically result in students who are more activated, and provided additional insight into conditions for successful interactive teaching. Finally, interactive teaching was shown to influence positively student motivation.     

A qualitative approach to understanding the role of lecture capture in student learning experiences

Lectures continue to be the dominant form of university teaching, and lecture capture technologies are tentatively taken up to support this form of delivery, rather than being used as a viable alternative. Much of the previous research, however, has been self-reports or survey-based, with far less attention given to qualitative explorations. This study aims to bridge this gap by using qualitative methods in order to examine students’ experiences of lecture capture provisions within the context of their own learning by utilising six focus groups to generate data. Thematic analysis was used to understand group opinions and experiences of lecture capture within university teaching. Two conceptual themes emerged: enhancing the learning environment and working and learning strategically. Results show that the value of lecture capture provisions could not be fully evaluated by students without considering their current learning environments. The main positive function of lecture capturing was to alleviate negative perceptions of lectures as a learning event, but it also provided students an opportunity to learn strategically. The extent to which lecture capturing develops and enhances the learning experience is discussed. Recommendations for how universities could utilise lecture capturing are proposed.     

Teaching Nonverbal Communication

Abstract

Lectures remain the primary method of instruction in higher education despite several limitations: Students typically lose interest during hour-long lectures, lectures lead to rote learning by some students, and lectures do not lead to development of higher-level conceptual thinking skills. As an alternative to a lecture on the topic, an active learning exercise was developed to teach students about nonverbal communication. The exercise was used with several classes, and students reported it was motivating, educational, and thought-provoking. Advantages of implementing active learning exercises in lecture courses are discussed.     

Linking Assessment Questions to a Research Article to Stimulate Self-directed Learning and Develop High-order Cognitive Skills in an Undergraduate Module of Molecular Genetics

Assessment plays a crucial role in the learning process, but current assessments focus on assessment of learning rather than assessment for learning. In this study, a novel method for open-book continuous assessment (CA) was developed. The aim was to encourage students to learn beyond the textbook by challenging students with questions linked to a research article. Research articles closely related to lecture contents were selected and released to students before the CA for perusal. CA questions were set at three different levels to assess conceptual understanding, application, and synthesis. The CA was administered to first-year undergraduate students majoring in life science as part of Molecular Genetics, a compulsory module. It contributed 10% of the student''s grade for the module. Students’ CA scores indicated that the majority could answer correctly all the questions. Students’ feedback on the CA showed that most of them praised the CA model for its novelty, motivation, and application. Only a few criticized it due to its poor coverage of lecture contents. Overall, this CA went beyond the traditional role of assessments in the assignment of scores and stimulated curiosity and self-directed learning.     

Investigating the effectiveness of speech-to-text recognition applications on learning performance,attention, and meditation

In this study, the effectiveness of the application of speech-to-text recognition (STR) technology on enhancing learning and concentration in a calm state of mind, hereafter referred to as meditation (An intentional and self-regulated focusing of attention in order to relax and calm the mind), was investigated. This effectiveness was further explored with regard to foreign language ability and gender. Finally, students’ perceptions towards STR-texts were surveyed. 60 non-native English speaking undergraduates participated in this study. All students were randomly assigned into either a control or an experimental group, with 30 students in each group. Two lectures, both in English but at different levels of difficulty, were given in a classroom environment. Students in the control group received a lecture containing only a video of the instructor and slides; students in the experimental group received the video of the instructor and slides as well as STR-texts of the lecture. The following main findings were obtained: First, STR-texts had a positive effect on the learning performance, attention and meditation of students. In addition, most students had positive perceptions regarding the usefulness of STR-texts for learning. This is because students in the experimental group received instructional content in both verbal (i.e., speech) and visual (i.e., STR-texts) forms, which made the content more comprehensible and easier to process. Second, during lectures with STR, high ability and female students had higher levels of attention and meditation in most cases compared to their counterparts. This finding can be explained by the difference in learning motivation and in the use of learning strategies. That is, high ability and female students are more interested in learning and display greater use of various learning strategies. Based on these results, it is suggested that educators and researchers integrate STR-texts during lectures in English in order to enhance learning and to increase the level of attention and meditation of non-native English speaking students.     

Effects of primer podcasts on stimulating learning from lectures: How do students engage?

A number of factors can influence learning from lectures such as students' prior knowledge, their motivation, the instructional design, the lecturer and so forth. Instructional aid techniques such as preparing class notes, giving quizzes (either planned or spot quizzes) and the like can be used to maximise learning. This study uses two well‐documented tools for learning from text—advance organisers and higher order questions—adapted for use with podcasts. Student evaluations of their experience of being primed for lectures with podcasts are described. The findings show that audio advance organisers and questions experienced by students have a positive influence on learning, because they help students bridge the conceptual distance between new and prior knowledge, better understand the topics in the lectures and stimulate thinking more deeply about the lecture's content and the possible applications of the subject of the lecture.     

Can Wii Engage College-Level Learners? Use of Commercial Off-the-Shelf Gaming in an Introductory Statistics Course

Technological advancements and growing dependence on media outlets as sources of information compete for the attention of individuals born in a rapidly expanding digital age. As a result, educators using traditional, nondigital teaching methods struggle with keeping students engaged in the classroom. The present study assessed the extent to which a digitally enhanced learning environment can improve student involvement in learning. A traditional behavioral statistics lecture was supplemented with Nintendo Wii video gaming to increase student content knowledge comprehension and engagement with course material. A mixed Analysis of Variance (ANOVA) revealed that those in the video gaming condition improved significantly more than those receiving traditional lecture only. This research suggests that students can learn difficult conceptual material (i.e., statistics) through more novel, interactive teaching methods.     

Effects of a Demonstration Laboratory on Student Learning

Laboratory and demonstration have long been used to supplement lecture in chemistry education. Current research indicates that students are better served by laboratories which exercise the higher-order cognitive skills, such as inquiry-based laboratories. However, the time and the resources available to perform these recommended types of laboratories are continually shrinking. Due to these factors, a demonstration-laboratory was designed to allow students to make observations through demonstration rather then through hands-on laboratory. For this study, the hands-on procedures of an inquiry style laboratory were replaced by an instructor demonstration of these same procedures. A significant difference was found between student conceptual understanding before and after the experiment, indicating that students performing the laboratory experiment and students viewing the demonstration-laboratory had an increase in conceptual understanding. However, no significant difference was found between the conceptual understanding of the two groups after the experiment, indicating that students learn roughly the same from both methods and that the demonstration-laboratory at least does no harm to the students conceptually. Long-term effects on student understanding were not measured. Student opinions comparing the demonstration laboratory to a hands-on laboratory were also collected and analyzed.     

MAGNETISM TEACHING SEQUENCES BASED ON AN INDUCTIVE APPROACH FOR FIRST-YEAR THAI UNIVERSITY SCIENCE STUDENTS

The study investigated the impact on student motivation and understanding of magnetism of teaching sequences based on an inductive approach. The study was conducted in large lecture classes. A pre- and post-Conceptual Survey of Electricity and Magnetism was conducted with just fewer than 700 Thai undergraduate science students, before and after being taught the concepts, in three academic years. For 2005 and 2006, overall, the students had a better understanding of concepts associated with electricity, but a majority of the students seemed not to understand magnetism after the teaching. Drawing on these findings, the teaching sequences of the magnetism topic were developed, and then implemented in the academic year 2007. The teaching sequences included demonstrations and visuals to help students infer rules and theories for themselves (inductive method). In addition, interactive notes, information on historical science discoveries about magnetic phenomenon, questions, student discussions, and magnetism problems were used to support student learning during lectures. Students in the academic year 2007 performed significantly better after the teaching. In addition, the students had a positive perception towards the teaching sequences, which allowed them to be involved more actively during lectures.     

Development of a support environment for first year students taking materials science/engineering

This paper is based on the experience acquired in teaching materials science/engineering to first year university students. It has been observed that students struggle with some of the fundamental materials concepts addressed in the module/course. This applies to delivered lectures but extends to the incorporation of tutorial sessions provided after lectures. Moreover, when students miss a lecture or seminar the acquisition and application of knowledge and concepts becomes problematic. Consequently, or perhaps inevitably, these students perform poorly in their assessments and their motivation for the subject suffers. A careful analysis of this situation and of the nature of interaction and engagement was performed to gain an insight into the reasons for this lack of performance. A common factor is that students do not dedicate sufficient time for reading and consolidation using the chapters/sections prescribed after each topic. They also do not attempt solving tutorial problems outside the formal contact hours. This reflection and personal evaluation is difficult to administer, resource intensive and yet potentially enables each student to monitor and evaluate their own learning and understanding. A multimedia learning technology‐based environment was created in which students could engage. This was located within the University of Wolverhampton Virtual Learning Environment (VLE) called WOLF. The students were able to progress independently but with access to tutor and peer support, help and advice. The use of non‐text animations and structures was used and seen as fundamental by the students in enhancing the taught course and in developing a deeper understanding of complex atomic and crystal structures.     

Lecture attendance is a pivotal factor for improving prospective teachers’ academic performance in Teaching and Learning Mathematics

The value and importance of lectures in higher education is part of a modern education discourse worldwide. This study aims to estimate the importance of lectures for prospective teachers of kindergarten, preschool and early primary school. We analysed academic achievements of prospective teachers who had either mandatorily or voluntarily attended lectures in the subject of teaching and learning mathematics. Students’ examination grades in a maths course with mandatory or voluntary lecture attendance were analysed with a logistic model testing the association between lecture attendance requirement and grades. We show that mandatory lecture attendance (1) more than double the odds of students receiving a pass grade when their situated and tacit knowledge was examined and (2) quadrupled the odds of students achieving the highest grade (pass with distinction) when both their understanding of elementary mathematics and their situated and tacit knowledge of teaching and learning mathematics were examined. Our study provides evidence for a significant positive role of lecture attendance for students acquiring skills in Teaching and Learning Mathematics. While attending lectures students receive situated tacit knowledge of the subject which is otherwise difficult, if not impossible, for them to obtain in a different way. The observed improvement may have an additional positive effect in being a step towards overcoming a maths anxiety, which is otherwise relatively common among prospective teachers.     

Is attending lectures still relevant in engineering education?

A case study was conducted on a group of undergraduate chemical engineering students to assess the relevance of attending lectures from a student perspective and to understand why these students attend and do not attend lectures with a view to developing approaches to teaching, which are of greater interest and benefit to student learning. The students were surveyed by means of a questionnaire-type survey, which collected both quantitative and qualitative data from them. The majority of students stated that lectures are still very beneficial to their learning and are not an out-of-date mode of education. The major reasons for lecture non-attendance were time priority and curriculum overload issues with other scholarly activities and poor quality teaching. The students provided a number of suggestions to improve lectures and lecture attendance, including the incorporation of active learning in lectures, linking lectures to assessment and adding extra value to what is already in the notes.     

An Experimental Comparison of a Conventional and a Project Centered Method of Teaching a College General Botany Course

Research on teacher behaviors that actively promote student intrinsic motivation to learn has been relatively scarce. In this article, 2 studies exploring the effects of teacher enthusiasm on both students' intrinsic motivation to learn and their pychological vitality are presented (Ryan & Frederick, 1997). In Study 1, a questionnaire including measures of intrinsic motivation, vitality, teacher enthusiasm, and numerous other positive teacher behaviors was administered to 93 college students. Among the teacher variables, enthusiasm was the most powerful unique predictor of students' intrinsic motivation and vitality. In Study 2, level of teacher enthusiasm (high vs. low) was manipulated in an experimental design with 60 college students. The students who received an enthusiastically delivered lecture subsequently reported greater intrinsic motivation regarding the lecture material and experienced higher levels of vitality. The authors speculate about possible mechanisms for and limitations to the positive motivational effects of teacher enthusiasm.     

E–Learning in Hong Kong: comparing learning outcomes in online multimedia and lecture versions of an introductory computing course

This paper evaluates the effectiveness of Web–based, highly interactive, and multimedia–rich e–learning materials by comparing students' learning outcomes in the lecture and online versions of an introductory computing course. The course versions differed only in that face–to–face lectures were replaced with e–learning modules in the online course; the other course elements (laboratory sessions, use of computer–mediated communications, examinations) were the same. The e–learning trial took place at the Hong Kong University of Science and Technology, where the first author taught the lecture course to 105 students, and the online course to 180 and 129 students in the following semesters. The lecture and online students achieved comparable factual learning outcomes and the online students outperformed the lecture students in applied–conceptual learning. Findings suggest that the use of carefully designed interactive e–learning modules fosters higher–order learning outcomes.     

Teachers' enthusiasm and humor and its' lagged relationships with students' enjoyment and boredom - A latent trait-state-approach

Following Pekrun's (2006) control-value theory of achievement emotions, we investigated carry-over effects and cross-lagged relationships between student-perceived teacher enthusiasm and humor and students' enjoyment and boredom both within and between university lectures. We used a latent state-trait approach to acknowledge the role of situational factors in this relationship. Data were collected from 559 university students (76% female, mean age 21.6 years) from seven different lecture courses. We assessed students' self-reported emotions and student-perceived teacher enthusiasm and content-related humor over a period of four lectures at three random points during each lecture course. The analyses revealed that all variables were influenced by previous measures within lectures; however, between lectures, only previous enjoyment and humor influenced the subsequent measure. When students experienced boredom, they perceived less teacher enthusiasm and humor. On the other hand, perceived teacher humor positively affected enjoyment within lectures.     

Self-explanation in the domain of statistics: an expertise reversal effect

This study investigated the effects of four instructional methods on cognitive load, propositional knowledge, and conceptual understanding of statistics, for low prior knowledge students and for high prior knowledge students. The instructional methods were (1) a reading-only control condition, (2) answering open-ended questions, (3) answering open-ended questions and formulating arguments, and (4) studying worked-out examples of the type of arguments students in the third group had to formulate themselves. The results indicate that high prior knowledge students develop more propositional knowledge of statistics than low prior knowledge students. With regard to conceptual understanding, the results indicate an expertise reversal effect: low prior knowledge students learn most from studying worked-out examples, whereas high prior knowledge students profit most from formulating arguments. Thus, novice students should be guided into the subject matter by means of worked-out examples. As soon as students have developed more knowledge of the subject matter, they should be provided with learning tasks that stimulate students to solve problems by formulating arguments.     

Learning Experience and Learning Effectiveness in Undergraduate Statistics: Modeling Performance in Traditional and Flexible Learning Environments*

This project investigates the relationship between student performance, past mathematics experience, and perceptions of statistics education for two groups of university students studying statistics in different learning environments. One group received the traditional form of teaching with lectures, whereas the other group studied in a more flexible learning mode where lectures were replaced with a computer‐managed learning tool and optional small‐group workshops facilitated by written lecture notes. The results on student learning experience show that, for both groups, student enjoyment of the course is positively related to their learning attitudes and to their perceived value of statistics education, and is negatively related to anxiety with regard to their performance in the course. There is some evidence that the group studying in the technology‐supported flexible learning environment experienced more assessment anxiety and consequently less enjoyment of the subject. There is also evidence that assessment anxiety has a negative effect on student performance that is exacerbated by a lack of prior mathematics experience. Hence, the flexible learning approach in statistics education, with minimal face‐to‐face teaching, may be especially inappropriate for these students.     

Enhancing large-class teaching: a systematic comparison of rich-media materials

Large cohorts (>200 students) are an ever-increasing presence in the UK higher education (HE) sector. Providing excellent teaching and learning to these large classes is an ongoing challenge for teaching faculty, a challenge intensified when the cohort comprises 85% non-native English speakers. This paper presents the findings of a project to supplement face-to-face lectures on a large campus-based taught MSc programme with a set of rich-media materials. These resources consisted of audio podcasts, audio-narrated slides, short video segments and full-video lecture capture. The aim of the study was to examine student usage of, and preference for, these different rich-media materials. Key findings are that students valued most highly the full-video lecture capture followed by the audio-narrated slides, using the materials primarily to consolidate their understanding and as revision aids. Students also emphasised the central importance of the face-to-face lecture – viewing the rich-media materials as complementary to, rather than as a replacement for the traditional lecture. Nor did the majority of students see the provision of videoed lectures as a reason for non-attendance at lectures. The findings of this study provide confirmatory evidence of the ongoing importance of the traditional lecture in large cohort HE teaching together with an acknowledgement of the benefits that rich-media materials can bring to the student learning experience.     

Peer tutoring in conceptual design

A peer tutoring scheme has been introduced into the Department of Engineering at the University of Liverpool to help 2nd year undergraduate students tackle conceptual design problems. Conceptual design is an iterative process consisting of a series of generative and evaluative stages, which gradually converge on a preferred conceptual solution. Students are generally less comfortable with the task of generating, evaluating and presenting ideas and this leaves them less able to tackle a conceptual design project without the help and intervention of available teachers or experts. Formally, the students were taught through lectures, coursework and critique sessions. Peer tutors were trained to facilitate group sessions whereby the students were able to discuss ideas, evaluate new concepts, generate solutions and learn to communicate more effectively within a non-threatening environment. The students developed problem-solving skills, became more confident and took more responsibility for their own learning. The peer tutoring process also had a positive effect on the tutors, who felt they had become more responsible and employable, improved their communication and leadership skills and deepened their own understanding of design, as a result of the peer tutoring experience.
