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.

mathematics proficiency english language student culture language of learning and teaching...
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.

Influence of School Characteristics on the Achievement of Secondary School Chemistry Students in the Cognitive Science process Skill of Evaluation in Kenya
influence school characteristics cognitive science process skill evaluation achievement...
Chemistry is one of the subjects that students sit for in the Kenya Certificate of Secondary Education (KCSE). The attainment of students in chemistry in KCSE has been quite low. An analysis of the past Chemistry examination papers taken in KCSE reveals that the papers test students’ competencies in various aspects of Cognitive Science Process Skill of Evaluation (CSPSE). It was hypthesised that school characteristics could be influencing students’ acquisition of various aspects of CSPSE. The school characteristics investigated were social set up (single – sex and co-educational schools) and school location (rural and urban schools). The aspects of CSPSE investigated were: reformulation of scientific statements, evaluation of experimental procedures, evaluation of inferences from scientific data, and evaluation of scientific arguments. Cross- sectional survey research design was used in this study. Cognitive Science Process Skills Test (CSPST) was constructed and administered to a stratified random sample of 386 Form Three Chemistry students drawn from Public County Secondary Schools in Rift Valley Province of Kenya. The findings of the study show that students from single-sex secondary schools performed significantly better than their counterparts from co-educational schools in all the categories of CSPSE. The school location did not have a significant influence on students’ performance on CSPSE.

It is well established that girls and boys perform differently in traditional examinations in most countries. This study looks at a sample of 754 school students in Kuwait (aged about 13) and explores how boys and girls differ in the performance in a range of tests related to learner characteristics. The fundamental question is how boys and girls differ in these learner characteristics and do any of the differences relate to examination performance. If the development of such learner characteristic is open to experiences in the formal learning situations, then this opens the door to possible ways to encourage the development of such characteristics, with possible concomitant enhancement of academic performance. It is found that girls outperform the boys in tests which measure extent of field dependency, extent of divergency and skills with the visual-spatial (all at p < 0.001). Confirming previous studies, the girls markedly outperform the boys in all school subject examinations but there are no differences in their measured working memory capacities. In looking at the relationships between various combinations of the measurements made, it is found that boys are much more dependent on working memory than girls in performing in examinations, and the boys are also much more dependent on employing skills related to divergent thought in achieving success in examinations. These observations are interpreted in terms of the way boys and girls learn, with girls being more conscientious and willing to memorise than the boys who, in turn, have to rely on working things out for success: girls tend to memorise; boys tend to try to work it out. This may offer an explanation of the greater success of girls in typical examinations where the accurate recall of information is so often the key to success.

The aim of this study was to determine mental models of 334 pre-school children concerning school. Children in the city center of Kastamonu in the Western Black Sea region of Turkey were included. Content analysis was conducted on pictures drawn by the children, and the models were split into two groups, scientific and nonscientific. The scientific group was split into three types; the nonscientific group, into four. About 40% of the children had a scientificbased school perception, while 60% were nonscientific. No significant difference was found between the mental models of females and males. Few studies have investigated mental models, so this study fills a gap, but further studies would aid the understanding of the relevant pedagogic architecture.

programmed instruction mathematics teaching science teaching...
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.

Understanding Mathematics: Some Key Factors
working memory capacity attitudes to mathematics difficulties in mathematics cognitive overload...
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.

An Event-Related Potentials Study of Mental Rotation in Identifying Chemical Structural Formulas
chemical structural formulas event-related potentials mental rotation rotation-related negativity...
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...
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.

Engineering Student’s Self-Efficacy Judgment to Solve Mathematical Problems in the Classroom or Online
self-efficacy perception mathematics students online learning face to face learning cognitive algebra...
This study explored in a sample of 560 high level education students their judgment formation to perceived self-efficacy to solve mathematical tasks. Students had to read 36 experimental vignettes describing educative scenarios to learn mathematics. Each scenario presented four manipulated pieces of information (learning modality, task difficulty, task relevance, and structure). After reading each scenario students were required to provide judgments regarding their believed self-efficacy to solve mathematical tasks described in the vignette by using a scale. Results showed that in regard to how students perceived their self-efficacy they could be grouped in two clusters (high and moderate). Most relevant factors to their judgment formation were task difficulty, task relevance and structure. Here, both groups used the same cognitive algebra mechanism to integrate factor information. Here, students valuated academic performance and feedback (e.g. difficulty and relevance) as most relevant even when they are conscious that learning is a primordial target. These and other results are discussed in the paper.

constructivism prospective physics teachers teaching practice teacher education...
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.

The aim of the research is to determine the perceptions of the preservice science teachers about the photosynthesis and to reveal the relation between these perceptions and the misconceptions of the existing concepts. In the research, field scanning method was used as a descriptive research method. The sample of the research is composed of 355 preservice science teachers trained in different universities. For the selection of the sample, purposeful sample selection was used and attention was paid to the fact that the preservice science teachers had taken the General Biology-I and General Biology-II courses at the undergraduate level in the determination of the class level to be included in the study. The "Photosynthesis Concept Achievement Test" (PCAT) developed by the researcher and composed of 4 questions was used as a data collection tool. Quantitative data obtained from the study were analyzed using SPSS.20 package program while content analysis was performed in the analysis of qualitative data. As a result of the research, it was determined that the preservice science teachers' perceptions of photosynthesis were in the direction of chemical and biological approaches and that the teacher candidates preferred the chemical approach rather than the biological approach. However, preservice science teachers who prefer the chemical approach have reached the conclusion that they are in much more misconception than the biologically approaching teacher candidates.

biology laboratory self-regulated learning strategies self-directed learning readiness attitude...
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.
