Abstract:
Harmful Einstellung effect creates a serious source of aversion for students in Mathematics. It may not be clear whether students fail Mathematics due to lack of knowledge or due to aversion arising from Einstellung effect. This study therefore investigated students’ susceptibility to harmful Einstellung effect in Mathematics instruction using logistic-empirical model approach. A cross-section of senior secondary school (SS 2) students of Alvana Model Secondary School Owerri, Imo State numbering 93 were continuously observed (using direct observational technique with observation schedule) and surveyed to decipher their susceptibility to harmful Einstellung effect. The result indicates increasing susceptibility to harmful Einstellung effect. That is, a high prevalence of Einstellung phenomenon was observed among students. It is important to note that this has consequently resulted in the increase of aversive behaviour in Mathematics learning. It was recommended among others that teachers should inform the students about harmful Einstellung effect during teaching and encourage them to think critically about any mathematical problem before finding solutions. Also, teachers should adopt some approaches when teaching Mathematics, such as, delayed formalization approach and target task approach.

Abstract:
This study was conducted to answer the question, "What is the description of the mathematical critical thinking ability of middle school students in Tidore city based on gender and background?". This question is essential to answer because it is motivated by the mathematical performance of students in Tidore is low nationally and is reinforced by the results of the 2015 and 2018 PISA and OECD surveys. Gender is used as a distinguishing factor because this factor is still culturally rooted in this area and affects the role of society in life socially. Tidore comprises three significant communities, namely coastal, urban, and mountainous communities, each of which has a unique pattern of social life. Therefore, researchers also use "background" as a distinguishing factor. Data collection was carried out in three schools representing the three communities using a questionnaire, math problems (arithmetic, geometry, algebra), and semi-structured interviews on two subjects (male and female) in each location. The results of the analysis show, based on gender and background the ability of students to think critically mathematically are categorized as sufficient (close to less) with a mathematical critical thinking (MCT) achievement ratio of 0.27. Male subjects had an achievement ratio of 0.3 (sufficient) higher than female subjects of 0.24 (insufficient). Based on the background subjects from urban areas had the highest MCT achievement ratio of 0.49 (sufficient) while the subject achievement ratio of the coast and mountains were 0.17 (insufficient) and 0.15 (insufficient), respectively.

Abstract:
The focus of this research was to verify if there was a link among anxiety toward mathematics, learning engagement, and their perception of technology's usefulness in mathematics. This ex-post research looked into the relationship and predictive degree of students' math anxiety, learning engagement, and perceived usefulness of technology to their mathematics achievement. Students' math anxiety and perceived usefulness of technology were found to be high in the study, whereas student engagement was found to be low and level of students' performance in mathematics was also high. Both math anxiety and students' perceptions of the utility of technology in learning have a significant impact on students' mathematics performance, but not on their engagement. The findings showed the importance of a high level of anxiety in improving student math performance. Additionally, math anxiety and the perceived usefulness of technology were discovered to be predictors of student mathematics performance. The findings suggest that anxiety, engagement, and perceptions of technology's usefulness should all be considered when improving students' general mathematics performance.

Abstract:
Research publications show that they are many different theories which explain how adults learn, but none of them individually fully explains what happens when adults learn, hence cannot be applied universally. Each theory has its own merits and demerits, therefore to maximise learning, a combination of theories should be used. Adult teacher educators’ familiarity with this knowledge base of adult learning improves effectiveness in meeting adult learner needs, since implementation of the most effective ways for adult learning is made possible. The current study sought to find out the nature of experiences of secondary school teachers recruited to be teacher educators at a secondary teachers’ college, had during the transition from teaching children (pedagogy) to teaching adults (pre-service mathematics and science teachers). Interviews were done, with the view to enable teacher educators to compare their experiences during training (as adult learners) in various teacher education institutions, teaching children at secondary school level, and teaching adults at the teachers’ college in the current study. Interview responses were coded to come up with themes which were analysed. Findings show that learning and application of adult learning theories is a missing link in teacher preparation institutions in Zimbabwe. In order to align teacher preparation with the current Zimbabwean curriculum, training institutions must prepare prospective teachers for both pedagogy and adult learning theories, so that they adapt as the situation requires. This resonates with metagogy, a hybrid of pedagogy and adult learning theories. Preparing teachers this way is in line with best practices, which engender competitiveness to deal with diverse teaching and learning situations, in the 21st century.

Abstract:
Mathematics learning still tends to be structuralistic and mechanistic. It resulted in students' difficulties and errors in understanding mathematical concepts and principles. Whereas mathematics is a human activity that is always in contact with their culture. One of the cultures that becomes the starting point for learning mathematics is a traditional house, such as the “Rumah Tuo”. The purpose of this study was to describe the mathematical activity at the Rumah Tuo. This type of research is a qualitative-research with an ethnographic approach. The research instrument used in the form of observation, interviews, and documentation. The results of this study are that there are mathematical activities carried out at Rumah Tuo, namely counting activities using Gantang Biheh, measuring activities in making poles in the form of a 16-sided prism, and designing traditional houses in such a way that they can be shaped like ancient means of transportation, namely ships. The conclusion of this research is that there are three mathematical activities through the “Rumah Tuo” culture, namely measuring, designing and calculating.

Abstract:
This study aims to describe the mathematical literacy of Indonesian students based on research articles published in the last decade. This study used a systematic literature review method by collecting 163 relevant journals and then re-selected to meet the inclusion criteria and the criteria for assessing the quality of study results. It was found information on the development of research analyzing the mathematical literacy of Indonesian students starting from elementary school, junior high school, high school, and College Level. The literacy level of students at the elementary level is still considered low, while at the junior high school level it is assessed from various perspectives ranging from the low mathematical literacy of students to the factors that influence it. At the high school level, students' mathematical literacy is also still low even though a mathematical literacy test has been carried out in the Indonesian context. Finally, mathematical literacy at the university level is found that different student learning styles will go hand in hand with different mathematical literacy abilities.

Abstract:
STEM problem-solving is a core standard in education to tackle the 21st-century challenge. However, the under-represented mathematics in STEM assessment has become an issue. Moreover, the existing frameworks of STEM problem-solving are suitable for assessing activity during teaching and learning. This study covers the limitations by developing a new mathematical problem-solving-based integrated STEM framework and applying it into practice. The new framework combines and integrates frameworks in every STEM discipline. It applies in developing scenario based-test with prompting questions to show the practical use of the framework. The test was administered to 31 of 7th graders students (M=12.29, SD=.46) to prove the consistency of the new framework and the effective role of scenario and prompting questions. The results revealed four types of flows in the problem-solving process posed by students with different in evaluating, representing, and designing phases. The flow of problem-solving and the indicators in a new model were consistent but shown as a dependent process. The scenario and prompting questions worked effectively regardless of a multidimensional prompting question. Several recommendations for developing a test based on the new framework are discussed. Quantitative analysis with large sample size is required for future study.

Abstract:
This study intended to explore and understand the academic experiences of senior high school students studying English in a distance modular approach. The researchers investigated the academic experiences, the challenges encountered, the techniques in facing challenges, and the suggestions in addressing the challenges. The four Grade 12 SHS learners of General Santos City National High School, one representing each track: Academic, TVL, Sports, and Arts and design, were the participants of this study who were selected through purposive sampling. The current qualitative inquiry is phenomenological in nature. The data were interpreted through coding, categorizing, and conceptualizing. It revealed that the academic experiences of the senior high school students are categorized into two themes; 1. Learners’ Learning Preferences and Time Management and 2. Learners’ Difficulty in Learning English. The learners experienced difficulty in understanding and comprehending lessons in English subjects. The findings also showed the learners’ learning preferences and the techniques employed in time management like the time blocking method. The challenges were the learners’ intrinsic and extrinsic motivation specifically rooted from being unmotivated and lacking parental support in tackling their learning difficulty; learners' learning preferences and time management specifically identifying their lack of time management technique; learning environment at home that shows unstable network connection and inability to allocate specific time for school work and chores; and learners' difficulty in learning English that shows the difficulty in understanding and comprehending lessons in English subjects.

Abstract:
Personal Finance, Investing, and Trading are life skills that prepare individuals to become financially comfortable in their lives and lead happy life. While some of these skills can be acquired from family members or can be drawn from first-hand personal experiences, training programs are found to make a profound positive impact. A questionnaire is administered to 278 stock market participants to understand the impact of stock market training programs conducted in the form of seminars and webinars. The study finds that the training programs have given substantial edge in their trading and investing activities and are worth spending time and money on them. Self-experiences, training programs, and stock market books are the most significant sources of stock market wisdom. Findings from this research can help financial intermediaries in better building investor awareness programs.

Abstract:
Students who exhibit hyperactive behavior can be at high risk such as failing at school, experiencing serious social problems, including difficulty getting along as well as conflict with family members, being hated by siblings, often scolded and punished by caregivers. All of these factors can have an impact on students' social lives and influence the emergence of chaos in student attitudes and behavior. Indicators of student hyperactivity include: 1) difficulty focusing, 2) often not doing assignments, 3) unable to sit quietly, 4) often flicking friends, 5) impulsive, 6) often monopolizing activities in social interaction. The impact of students' hyperactive behavior is: 1) decreased learning achievement, 2) lack of harmony in social relations with peers. Hyperactive behavior is influenced by the pattern of parental care that is authoritarian and unattended. This research aims to improve the behavior of hyperactive students in teaching and learning activities in SMP Negeri 3 Surabaya with the method of self-counseling. The type of research used is qualitative research in the form of case studies of students who behave hyperactively. The techniques used in collecting data are interviews, observation, and documentation analysis. The data obtained were analyzed by qualitative descriptive analysis. The results showed that hyperactive student behavior can be improved by using the self-counseling method in teaching and learning activities. This is indicated by an increase in the activity of students in the first cycle of students who are active at 85.71% and in cycle 2 by 100%. from the initial value (62%) then cycle 1 (75%) and cycle 2 (85%). The action of the first cycle grade average value increased to 79.18 (completeness 52.6%), in the second cycle increased again to 87.87 (completeness 86.8%).

Abstract:
Picture Word Inductive Model (PWIM) is an inquiry-based vocabulary strategy which uses pictures to transmit information to the learners. This study investigated how PWIM affected the vocabulary achievement and attitude of the Grade 8 students. There were 50 participants of the study, 25 from the group exposed to PWIM and 25 from the group not exposed to PWIM. The vocabulary achievements of the students were identified using the 64-item teacher-made pre-test, posttest, and retention test. Students’ attitudes towards vocabulary learning were determined through a 20-item Likert-Scale Questionnaire on The Learners’ Attitude Towards Vocabulary Learning adapted from Gimolatan (2016). Results showed that the group exposed to PWIM strategy outperformed the unexposed group in vocabulary achievement in terms of posttest and retention test. Non-PWIM strategy was able to increase the students’ vocabulary achievement, but the increase was not as high as of the learners exposed to PWIM. Also, the students exposed to PWIM improved their attitude towards vocabulary learning from moderately positive to positive attitude while the group not exposed to PWIM remained to have a moderately positive attitude. Moreover, the vocabulary achievement of students exposed to PWIM was significantly higher than the students who were not exposed to PWIM. There was also a significant difference on the attitude of the students exposed and not exposed to PWIM towards vocabulary learning. Thus, PWIM was effective in improving the students’ vocabulary achievement as well as in enhancing their attitude towards vocabulary learning.

Abstract:
In developing countries and Nigeria in particular more and more educated people are wallowing in poverty due to diminishing standards of living. Despite the launch and re-launch of the universal Basic Education scheme by successive government in Nigeria since 1999, inequalities relatively to standards of living chances have remained little altered. This study makes use of annual time series data sourced from the world bank development index (WDI) covering the period of 1981 to 2017. Jarque-Bera Normality test, Unit root test, test for multicorrelation, cointegration test were used for the pre-test while the Fully Modified Ordinary Least Squares (FMOLS) approach was used for the estimation. The result shows that educational attainment (=0.029, t = 7.986, p 0.05) and formal education complementary skills ( = 0.00001, t = 3.752, p 0.05) exert a significant positive effect on household standard of living in Nigeria. Income redistribution ( =-0.019, t = -2.112, p 0.05) does not show any effect on household standard of living in Nigeria. The study submitted that educational attainment and formal education complementary skills contribute positively to household standard of living.

Abstract:
The purpose of this study is to understand the essence of language action in legal construction as a means of communication that should rely on language grammar in interpreting the meaning of sentences. Such a method is an attempt to avoid the different interpretations of the multiple interpretations of the meaning of language. The simplification of legal language must be linked to the content of the rules, where there are two arguments regarding "intentions and extensions", before carrying out legal interpretation, then interpretation is generally understood as a process, action, series of interpreting and explaining the meaning of something that is less clear or opinion, view of the context in which it is interpreted. This study uses a normative juridical method that explains the interpretation of manuscripts, legal principles and principles, legal rules, theories and legal doctrines that apply as a tool to understand the meaning of legal language communication and to understand the substance of a statutory regulation. The research approach uses a conceptual approach to examine and examine the subject matter. The consequences of blurred inter-connections result in a disparity in the factual application of the law which is correlated with a “policy during decision-making” in a formulaic policy which is a “policy” context. Based on these aspects, especially in language action, it is essentially an "effort in realizing clarity of meaning in laws and regulations so that they are in accordance with current and future implementation and conditions.
