Control engineering,system theory and mathematics: the teacher's challenge

The principles, difficulties and challenges in control education are discussed and compared to the similar problems in the teaching of mathematics and systems science in general. The difficulties of today's students to appreciate the classical teaching of engineering disciplines, which are based on rigorous and scientifically sound grounds, are discussed. The new demands for modern engineering education assume that the mathematical skills of the students in modelling, analysis, synthesis, simulation and validation of control problems improve significantly, which sets a major challenge to the education system. To meet that challenge new activating teaching methods are needed, which together with traditional studies bring the students closer to practical applications. In the current paper two new teaching methods are presented, which are aimed at bringing the control world near the student more easily than the traditional courses do. These example cases are control courses in the net with self-study sections, interactive repetitive questions, problems with complete solutions (both pen and paper and computer problems). Also, new ‘interactive laboratory exercises’ have been included, where the students prepare their preliminary problems first, and after that test the controller with a real process over the net (from their home or from a computer class).     

Effects of integrating mobile technology-assisted peer assessment into flipped learning on students’ dance skills and self-efficacy

ABSTRACT

Dance courses aim to not only intensify learners’ dance skills, but also cultivate their personal dancing features, self-confidence, self-reflection ability, creative power, appreciation ability, to name just a few, in order to attain much higher level artistic performance. In the present study, an approach which integrates mobile peer assessment into flipped learning is proposed. Moreover, a 9-week experiment was conducted to explore the effects of the approach on students’ dance skills, self-efficacy, and learning satisfaction. The results indicated that the students learning with the integrated mobile peer assessment and flipped learning approach had better dance skills than those learning with the conventional flipped learning approach and traditional instruction. In terms of self-efficacy, the students learning with the conventional flipped learning approach outperformed those learning with the proposed approach and traditional instruction. In terms of learning satisfaction, the conventional flipped learning approach outperformed the traditional instruction. Discussion and suggestions are provided accordingly. It is suggested that teachers who want to incorporate flipped learning into dance courses may decide whether to combine peer assessment according to the teaching objectives.     

Applied and academic A levels: is there really a need for the applied track in UK further education?

The term ‘applied track’ in UK further education has been used to refer to the applied A level, the vocational, coursework-based version of the traditional academic A level. Vocational and coursework-based courses are often criticised for being easier than academic courses, for only attracting students who do not satisfy the requirements to take academic courses and for not developing in students the skills they need to be successful in higher education. This paper considers the extent to which these criticisms may be justified and explores the reasons why students chose to take an applied A level. The study involved 666 students at a large, mixed sex sixth form college in the UK, who were taking both applied and academic A levels. Although statistical analysis showed that students on the applied course performed worse than students on two academic courses once their different GCSE scores had been accounted for, it was also found that the applied students were relatively well qualified, that they were generally well motivated and hard working, and that they were extremely satisfied with the course. Finally, it is suggested that perhaps universities are misguided in assuming that applied courses do not develop in students the skills that they need to be successful in higher education.     

Evaluation of the effectiveness of remedial reading courses at community colleges

Limited research is available on the effectiveness of remedial college courses. The present study evaluated the effectiveness of two instructional approaches for developmental reading courses at a community college in the southwestern United States. The instructional approaches were traditional textbook-based instruction and strategic-reading instruction. The sample consisted of 64 participants. Half (n = 32) of the participants were in the control group (n = 32) and received traditional textbook-based instruction; the other half (n = 32) were in the experimental group and received strategic-reading instruction. All participants completed the Nelson-Denny Reading Form G at the beginning of the semester and then again 12 weeks later, at the end of the semester. The data were then statistically analyzed to identify any relationships between the type of instruction and the differences between the students’ pretest and posttest scores. The null hypotheses for H1 and H2 were rejected because the results of the paired t tests indicated that both traditional textbook-based instruction and strategic-reading instruction have a statistically significant positive effect on students’ performance on the test. A one-way ANOVA was conducted to determine whether the pretest/posttest difference scores varied based on the type of instruction. The findings showed that both methods of instruction were equally effective in improving the reading comprehension skills of community college students in a developmental reading course. Based on the findings, community college leaders are encouraged to assess the effectiveness of the instructional methods used in developmental courses to ensure at-risk community college students are receiving the most beneficial instruction.

The MSU Educational Technology Certificate Courses and Their Impact on Teachers’ Growth as Technology Integrators

The Educational Technology Certificate (ETC.) courses at Michigan State University are a set of three courses that can be taken as a standalone qualification or as the first three courses in the Master’s of Educational Technology degree. Together, the courses emphasize the development of technology skills and advanced mindsets for technology integration in the classroom. In this article, we provide examples of our approach to the teaching of technology skills and mindsets in ways that are adaptable across four distinct modes of instruction (online, hybrid, overseas and faceto-face). We also present student feedback and survey data that inform a critical evaluation of the program’s effectiveness. Findings suggest that the certificate courses help students to gain technological skills, to become more confident users of technology and more likely to help colleagues with tech-related questions. Interestingly, respondents also reported feeling like better teachers, in general, after taking these courses.     

Teachers’ use of class time and student achievement

We study teachers’ choices about how to allocate class time across different instructional activities, for example, lecturing, open discussion, or individual practice. Our data come from secondary schools in England, specifically classes preceding GCSE exams. Students score higher in math when their teacher devotes more class time to individual practice and assessment. In contrast, students score higher in English if there is more discussion and work with classmates. Class time allocation predicts test scores separate from the quality of the teacher's instruction during the activities. These results suggest opportunities to improve student achievement without changes in teachers’ skills.     

Revising a College 101 Course for Sustained Impact: Early Outcomes

ABSTRACT

In response to strikingly low completion rates in public 2-year colleges, including for students who are well-prepared academically, most community colleges across the country offer student success courses as one approach to improving outcomes for students. Some colleges have begun to revise these courses in response to research indicating that their impact fades over time. This article examines Bronx Community College’s efforts to restructure their student success course into a First Year Seminar (FYS) that integrates college orientation activities, disciplinary content, and academic success skills. The course emphasizes student-centered pedagogies in order to encourage learning that persists beyond the semester of participation. We use mixed methods to assess the early outcomes of students in FYS courses and understand whether and why the course’s impact has the potential to be sustained. Using propensity score matching to compare 1,138 FYS participants to 1,138 similar nonparticipants, we find early evidence that the FYS approach leads to positive outcomes, including higher grade point averages (GPA) and earning more credits. Using classroom observations (N = 40), instructor interviews (N = 10), and interviews with participants (N = 27), we find that FYS appears to facilitate student-centered, contextualized, and applied learning, thereby helping students apply their FYS-related skills in future courses. This study has implications for reforming student success courses in a way that achieves long-term positive student outcomes.

The Collaboration of Cooperative Learning and Conceptual Change: Enhancing the Students’ Understanding of Chemical Bonding Concepts

The main purpose of this study was to investigate the effects of cooperative learning based on conceptual change approach instruction on ninth-grade students’ understanding in chemical bonding concepts compared to traditional instruction. Seventy-two ninth-grade students from two intact chemistry classes taught by the same teacher in a public high school participated in the study. The classes were randomly assigned as the experimental and control group. The control group (N?=?35) was taught by traditional instruction while the experimental group (N?=?37) was taught cooperative learning based on conceptual change approach instruction. Chemical Bonding Concept Test (CBCT) was used as pre- and post-test to define students’ understanding of chemical bonding concepts. After treatment, students’ interviews were conducted to observe more information about their responses. Moreover, students from experimental groups were interviewed to obtain information about students’ perceptions on cooperative work experiences. The results from ANCOVA showed that cooperative learning based on conceptual change approach instruction led to better acquisition of scientific conceptions related to chemical bonding concepts than traditional instruction. Interview results demonstrated that the students in the experimental group had better understanding and fewer misconceptions in chemical bonding concepts than those in the control group. Moreover, interviews about treatment indicated that this treatment helped students’ learning and increased their learning motivation and their social skills.     

The effects of a competency‐oriented learning environment and tutor feedback on students’ reflection skills

This study investigates the effects of a competency‐oriented course and the effects of feedback training on students’ reflection skills. Thirty‐one nursing students enrolled in a conventional course with lectures and assignments following a traditional test. Subsequently, they enrolled in a competency‐oriented course, which included more performance‐oriented tasks based on competencies and a performance‐based assessment. In both courses, half of the students received feedback on their assignments from tutors who were trained in feedback skills (experimental group), while the other half of the students received feedback from non‐trained tutors (control group). After each course, all students wrote a reflection report. Results show that students’ reflection reports after the competency‐oriented course were of a higher quality than the reports after the conventional course. Contrary to our expectations, the quality of the reflection reports of the control group (students supervised by non‐trained tutors) was significantly higher than the quality of reflection reports of the experimental group (students supervised by trained tutors). This study shows that a competency‐oriented design of courses enhances students’ reflection skills, but that the training in feedback skills needs to be reconsidered.     

Students teach students: Alternative teaching in Greek secondary education

The students of a Greek junior high school collaborated to prepare the teaching material of a theoretical Computer Science (CS) course and then shared their understanding with other students. This study investigates two alternative teaching methods (collaborative learning and peer tutoring) and compares the learning results to the traditional learning context. A test was used to measure all participating students’ learning results and a questionnaire was distributed to record participant student attitudes towards the alternative teaching conditions. The questionnaire was designed to evaluate each aspect in terms of perceived knowledge, experience, satisfaction, diversity, oddness and interest. The analysis explores potential differences of students’ learning results between alternative and traditional teaching and also differences in the two aspects in relation to students’ preferences. Results provide evidence that active-learning methods can promote positive attitudinal shifts and improve skills in creativity, teamwork, collaboration and communication. Students perceived higher levels of learning than with traditional teaching. Finally in terms of students’ preferences, the majority wanted to have more courses taught with active-learning methods.     

Blending Synchronous Face-to-face and Computer-Supported Cooperative Learning in a Hybrid Doctoral Seminar

Online education is often assumed to be synonymous with asynchronous instruction, existing apart from or supplementary to face-to-face instruction in traditional bricks-and-mortar classrooms. However, expanding access to computer- mediated communication technologies now make new models possible, including distance learners synchronous online attendance of face-to-face courses. Going beyond traditional uses of videoconferencing (e.g., real-time remote viewing with limited student interaction), this article describes the use of freely available technologies to support synchronous cooperative learning activities involving both face-to-face and hybrid doctoral students. Specifically, we describe the rationale behind pedagogical choices and specify how various technologies were re-purposed to create a virtual classroom space in which all possible combinations of face-to-face and hybrid students worked together in multiple small-groups across single class sessions. Implications for course development, the implementation of cooperative learning activities in online settings, and the use of both synchronous and asynchronous methods of online instruction are discussed.     

Preliminary Study: Special Education Doctoral Students’ Perceptions of Self-determination

This preliminary study investigated 118 special education doctoral students’ knowledge of and attitudes toward self-determination. In addition, this study examined the relationship between self-determination coursework and special education doctoral students’ perceptions of how well they were prepared for implementing self-determination in their future careers. The results indicated that although the majority of respondents possessed adequate knowledge of self-determination concepts, they reported lacking confidence in identifying how it can be taught and assessed. Most of the respondents indicated that they would integrate self-determination knowledge and skills into their future teaching; however, more than one-half of the doctoral students felt that they were unprepared with regard to the instruction of self-determination. Also, the findings indicated that there were statistically significant relationships between pre-service courses and doctoral students’ perceptions of self-determination. The results of this study showed a gap in current doctoral students’ knowledge about self-determination and confidence related to application within pre-service teaching.

大学生的可雇佣性是指大学生成功就业与可持续就业的能力品质。可雇佣性只有融入课程,才有可能转化为大学生的实际能力。参考瓦伦、约克和奈特的可雇佣性融入课程的设计方法,结合我国大学课程设计现实,提出三个层面的课程设计方式,分别是:以可雇佣性为导向的课程体系设计、可雇佣性技能嵌入核心课程、基于可雇佣性教学的课程实施方案设计。运用这些设计方式,需要特别注意三点:一是所设计的课程体系、核心课程与教学方案尽可能保持一致性,二是充分考虑专业属性与市场需求,三是提防课程设计"学生工作化"。     

The ability to understand and use conceptual change pedagogy as a function of prior content learning experience

This research examined the relationship between content instruction and the development of elementary teacher candidates' understanding of conceptual change pedagogy. Undergraduate students (n = 27) enrolled in two sections of a science methods course received content instruction through either traditional or conceptual change methods, followed by instruction about conceptual change pedagogy. Candidates were interviewed pre- and postinstruction about their content and pedagogical knowledge and also wrote conceptual change lessons. Twelve of the 27 subjects were videotaped teaching in the field. Results indicate that prior to instruction, most candidates had weak content knowledge and held traditional pedagogical conceptions. After instruction, students in the conceptual change group had significantly larger gains in their content knowledge than those in the traditional group, gave qualitatively stronger pedagogical responses, and used conceptual change strategies more consistently in practice. These results indicate that personal experience of learning science content through conceptual change methods facilitated the development of understanding and use of conceptual change pedagogy in teaching practice. Thus if conceptual change methods are to be incorporated into teacher candidates' repertoire, science content courses that students take prior to teacher education should be taught using conceptual change pedagogy. In addition, courses in science education should use pedagogy more in line with that taught in methods courses.     

The effects of new science curricula on student performance

This study summarizes the results of a quantitative synthesis of the retrievable primary research dealing with the effects of new science curricula on student performance. This study synthesizes the results of 105 experimental studies involving more than 45,000 students and utilizes the quantitative synthesis perspective to research integration known as meta-analysis (Glass, 1976). A total of 27 different new science curricula involving one or more measures of student performance are included in this meta-analysis. Data were collected for 18 a priori selected student performance measures. The results of this meta-analysis reveal definite positive patterns of student performance in new science curricula. Across all new science curricula analyzed, students exposed to new science curricula performed better than students in traditional courses in general achievement, analytic skills, process skills, and related skills (reading, mathematics, social studies and communication), as well as developing a more positive attitude toward science. On a composite basis, the average student in new science curricula exceeded the performance of 63% of the students in traditional science courses.     

“Do I need research skills in working life?”: University students’ motivation and difficulties in quantitative methods courses

This study explored university students’ views of whether they will need research skills in their future work in relation to their approaches to learning, situational orientations on a learning situation of quantitative methods, and difficulties experienced in quantitative research courses. Education and psychology students in both Finland (N = 46) and the USA (N = 122), who thought that they would need research skills in their future work, differed significantly from the students who were not sure whether they would need these skills. The students, who considered research skills important for their future work, were more task-oriented, used a deeper approach to learning and experienced fewer difficulties in the learning of research skills than other students. This finding implies that experiences in learning, learning approaches and situational orientations are related to expectations about future work. For instruction, this means that if we were somehow able to change students’ experiences and orientations towards research into a more positive direction, students might be better prepared for their future work.
