This study provides a framework for the production of Hypermedia Instructional package. It also assessed the effectiveness of hypermedia instructional mode of delivery on students’ performance in Chemistry. This is with a view of improving the learning of Chemistry which may eventually help to improve students’ performance. The developmental study employed a pre-test, post-test control group design. The research sample consisted of 60 private secondary school students in Osun State with an enrolment of 30 students from each of the two schools selected. The students were thereafter assigned to experimental and control groups. The stimulus material used for the experimental group was the Hypermedia Instructional Package, while the Control group received instruction with similar content through the conventional method. The test instrument used was Hypermedia Learning Achievement Test (HLAT). Content and face validity of the instrument used was carried out by experts in the area of tests and measurement. The Cronbach’s alpha reliability coefficient for the HLAT gave a value of 0.72. Data collected were analyzed using descriptive and inferential statistics. Results obtained showed that students exposed to the Hypermedia Instructional Package (HIP) performed significantly better than those exposed to the conventional teaching method (t = 5.458, df = 58, p < 0.05). Results also revealed a significant difference in the retention ability of students in Chemistry between those exposed to the package and those that were not (t= 6.842, df=58, p<0.05). The study concluded that the use of HIP was an intervention which improved students’ performance retention and attitude towards Chemistry.

Facilitating effective mathematics learning and higher mathematics achievement have long been recognized as a key to the scientific and technological advancement of the African continent. While the central role that language proficiency plays in mathematics teaching and learning has received an overwhelming research attention in the literature over the past two decades, this is not the case among African policy-makers and political leaders. Drawing mainly from our professional experiences as mathematics educators and from the international research literature, our primary intent in this paper is to answer this question: How does the learning of mathematics in English at the basic school level help or hinder students’ mathematical proficiency? To answer this question, the paper is organized as follows. The first part, the introduction, gives a brief overview of the language of learning and teaching in Africa. The second part describes the method and conceptual framework undergirding the research. In the third section, we have analyzed the effects of mathematics learning and teaching through English for basic students whose mother tongue is a Ghanaian language. The conclusion offers four recommendations for developing and improving the mathematics proficiency of students in basic schools.

This study examined Programmed Instruction (PI) a panacea to students’ dwindling interest in mathematics. Descriptive research of survey design was adopted for the study. A questionnaire was designed to collect data from a sample of seven hundred and fifty (750) respondents which include 700 Students and 50 Teachers from Public and Private Secondary Schools in Ado-Ekiti Local Government Area of Ekiti State in Nigeria. The study revealed that usage of programmed instruction beef up curiosity in mathematics students and resulted to greater retention and mastery of subject matter. Also, the study revealed that lack of trained personnel to help guide students in the use of programmed books, scarcity of programmed books in the society, high cost of procuring programmed books and machine and lack of necessary infrastructural facilities have been the factors militating against the implementation of programmed instruction in schools. Based on the findings, it was recommended that curriculum experts should develop various using the programmed instruction approach. Government should release fund for the development of programmed books and school authority should encourage their teachers to attend seminars and workshops, were they could gain knowledge of how to implement programmed instruction and other pedagogical skills that will enhance the teaching and learning of mathematics. Also, there should be provision of necessary infrastructural facilities in schools for easy implementation of programmed instruction.

Mathematics is well known as a subject area where there can be problems in terms of understanding as well as retaining positive attitudes. In a large study involving 813 school students (ages approximately 10-12) drawn from two different school systems in Pakistan, the effect of limited working memory capacity on performance in mathematics was explored along with a survey of areas of difficulty and student attitudes. This involved looking at student perceptions of their experiences, the nature of the difficulties they have with mathematics and possible reasons for these difficulties. The overall aim is to explore the extent of the effect of working memory and to gain insights so that practical ways forward to enhance mathematics education can be identified. It was found that limited working memory capacity has a very strong influence on performance, confirming other studies. Indeed, if the cognitive load exceeds the capacity of working memory, understanding becomes a casualty, with consequent attitude deterioration. Students need to be able to see that mathematics has a purpose in being able to be applied to real-life situations. However, attempts to develop applications may often generate further working memory overload. Curricula devised by those outside the classroom can sometimes be inappropriate while topics causing the greatest problems at these ages and include areas of geometry, statistics and the applications of mathematics.

Creativity is regarded as one of the cornerstones for economic and social progress in every society. There are two possible ways to get creative people to work for an enterprise or community. The first is by attracting creative employees by good working conditions – a solution for those who can afford such an approach. For communities that are not so rich, the only solution is to foster creativity by education and by helping small and medium enterprises to create products based on creative ideas and innovations. In Slovenia, proposals for nourishing creativity and innovations emerge from the government thus forgetting that creativity does not start at University or on the first day of employment. To increase creativity, immediate action should be taken throughout the educational system, recognizing that society needs not only creative artists but scientists, economists and engineers as well. Through the analysis of the legislation, syllabi and textbooks, it can be recognized that they do not promote or even allow creativity in science education; even more, they can be regarded as creativity killers. In such a way key documents and teaching resources are placing creative science teachers in the position of guerrillas in a battle against prevailing teaching methods influenced by highstakes external exams or measurable outcomes. To improve science creativity, the legislation should be changed to give creativity appropriate value, and teachers must be educated to use methods that increase creativity in students, with the aim of producing open minds that will be able to work in a creative way.

The purpose of this study was to investigate how mental rotation strategies affect the identification of chemical structural formulas. This study conducted event-related potentials (ERPs) experiments. In addition to the data collected in the ERPs, a Chemical Structure Conceptual Questionnaire and interviews were also administered for data collection. Eighteen university students majoring in chemistry were recruited. In the ERP experiments, the participants were required to identify 2D figures, 2D chemical structural formulas, 3D objects and 3D chemical structural formulas. The contours of 2D figures are similar to those of 2D chemical structural formulas, but they contain no content knowledge. Likewise, the contours of 3D objects are similar to 3D chemical structural formulas without content knowledge. The results showed that all students used similar strategies of mental rotation in identifying 2D figures, 3D objects and 3D chemical structural formulas. However, the high-achieving students used different strategies in identifying 2D figures and chemical structural formulas, while the low-achieving students tended to use similar strategies of mental rotation in identifying both 2D figures and chemical structural formulas. The results indicate that some of the difficulties in identifying 2D chemical structural formulas that students encounter are due to their inappropriate strategies of mental rotation.

concept maps meaningful learning teaching science

Muhammad Safdar , Azhar Hussain , Iqbal Shah , Qudsia Rifat


...

This paper describes the procedure of developing an instructional tool, ‘concept mapping’ and its effectiveness in making the material meaningful to the students. In Pakistan, the traditional way of teaching science subjects at all levels at school relies heavily on memorization. The up-to-date data obtained from qualitative and quantitative research strongly supports the value of concept mapping as an instructional tool both for cognitive and affective gains. This study seeks to contribute to this development by considering how the insights of Ausubel can be converted into an effective and efficient instructional method. It was found that concept maps help improving achievement of the students and make learning more meaningful so that retrieval is possible.

The purpose of the present study is to investigate pre-service history teachers’ perceived self-efficacy and the effect of pedagogical formation training on this perception. The study is based on a one-group pretest-posttest research design, which is a type of pre-experimental design. For the purpose of the study, in the first week of the formation training, the “Teachers’ Sense of Efficacy Scale” developed by Tschannen-Moran and Hoy and adapted to Turkish by Capa, Cakiroglu and Sarikaya was administered as a pre-test to a group of 178 pre-service history teachers who underwent pedagogical formation training in 2016-2017 academic year in two different universities in Turkey. The same scale was administered again as a post-test at the end of the 28-week training. The study has found out that the pedagogical formation training did not make a significant difference in pre-service history teachers’ perceived self-efficacy except for the classroom management subscale, in which the self-efficacy scores of pre-service history teachers decreased after the pedagogical formation training.

This study aims to explain the extent to which prospective physics teachers’ views and practices are consistent with the constructivist framework. A case study design was employed as the research approach. The study was conducted with 11 prospective physics teachers attending a state university in Turkey. Data was collected through semi-structured interviews, observation notes and lesson plans. The interview guide consisted of questions which allowed the interviewer to probe participants’ views of constructivism based on 5E learning model. Such questions as “how do you plan your teaching?” (introducing new topics, continuing the lecture, types of questions to ask, evaluating students’ understanding etc.) were included in the interview. Following the analysis of the interview data, participants’ profiles were classified into three categories: traditional, transition and constructivist under the dimensions “beginning of a lesson,” “learning process,” “learning environment” and “assessment.” Observations were carried out using an observation checklist consisting of 24 items based on 5E learning model. Another checklist developed by the researchers was used to evaluate participants’ teaching qualifications. Interview results showed that seven participants had transitional, three had constructivist and one had traditional views. However, none of the participants were observed to exhibit constructivist teaching styles. Moreover, observation and interview results were consistent only for six participants, indicating that almost half of the participants had difficulty putting their views into practice.

Self-regulation is an active and constructive process in which students regulate and observe their own behaviour, motivations and cognition by setting their own goals during their learning process. In this study, the aim is to investigate the effects of biology laboratory practices that are supported by self-regulated learning strategies on students’ readiness for self-directed learning and their attitudes towards science experiments in laboratory settings. This study, which was undertaken as a quasi-experimental study in accordance with the pretest-posttest design with a control group, was implemented. Second year students who studied science teaching in the faculty of education at a state university in Konya in the academic year of 2018-2019 made up the sample of this study. There were two groups in the study which were “The Control Group” and “The Experimental Group”. In order to measure the students’ self-directed learning readiness levels, “Scale of Self-Directed Learning Readiness in Laboratory” was used and to measure attitudes towards science experiments “Scale of Attitudes towards Science Experiments” was utilized. Both scales were implemented as pre-tests before the study and as post-tests after the completion of the implementation process. The analysis of the data was conducted via SPSS 18. Independent samples t test was conducted to understand whether biology laboratory practices supported with self-regulated learning strategies have any effect on students’ readiness for self-directed learning and their attitudes towards science experiments in laboratories. According to the findings of the study, biology laboratory practices supported with self-regulated learning strategies were observed to make a significant difference in favour of the experimental group considering their self-directed learning readiness and their attitudes towards science experiments.

In this study, it was aimed to investigate the academic motivations and academic achievements of pre-service visual arts teachers in the Division of Art Education in the Department of Fine Arts in the Faculty of Education in terms of some variables. The study group consisted of 127 (79 female/ 48 male) students in the division of art education. As the data collection tool, the “Academic Motivation Scale (AMS)”, developed by Vallerand et al. and then, translated into Turkish for university students by Karaguven, was used to find out the academic motivations of students, and the personal information form was used to get the personal information of students in the study. In the research, in which the relational screening method was used, the descriptive analysis was applied to determine the motivation levels of pre-service visual arts teachers; independent sampling t-test to compare their average scores according to gender; one-way variance analysis to test according to the class variable, and Pearson Correlation test to determine the relationship between their academic motivation and academic achievement. The findings of the study show that the intrinsic and extrinsic motivations of pre-service visual arts teachers are at a good level. It was found that the amotivation levels of pre-service visual arts teachers were at a low level. As the average scores according to gender were investigated, the meaningful difference was encountered in favour of female participants for intrinsic motivations. It was found that the intrinsic motivations of females related to the achievement were higher. An increase, from 1st year to 4th years students, was observed in terms of the academic motivation levels of pre-service visual arts teachers according to the class variable. However, no meaningful difference was encountered between the average scores of the students' academic motivations according to the class variable. It was found that the relationship between academic motivation and academic achievement was low.
