In the 21st century, learning requires high-level thinking processes and mastery of technology. The benefits of using technology accompanied by high-level thinking include 1) having many alternative solutions to problems, 2) be a good co-worker, and 3) being more independent in finding solutions. Also, learning mathematics is one of the main lessons in class and has the main characteristics of structured learning and has a systematic flow. The attributes of existing mathematics learning may support the technology learning process, which also has an orderly system and algorithm. This study employed a cross-sectional survey—it exploring high-level thinking and TPACK in mathematics learning. The subject was 182 pre-service mathematics teachers in Universitas Muhammadiyah Purwokerto, Indonesia. This study showed high-level thinking, and TPACK indicated that the item was sufficient to perform factor analysis. The analysis results found that the Kaiser Meyer-Oikin (KMO) value for items in the high-level thinking construct questionnaire with 12 items showed 0.657 (l> 0.50). Subsequently, in TPACK construct questionnaire with 32 items showed 0.783. The results stated that higher-order thinking is the essential capital in learning mathematics. Therefore, learning mathematics also demands the dynamism of technological developments to support the success of learning mathematics.

This study aims to develop an augmented reality (AR) learning media to improve the mathematical spatial ability of junior high school in geometry material. The method used in this study is a research and development method by following the steps of level 3 development. In this study, the product developed was augmented reality learning media. Data collection techniques are unstructured interviews, questionnaires and tests with information sources from mathematics education lecturers, two junior high school teachers as material validators and informatics engineering lecturers as media validators. The data analysis technique in this study used descriptive qualitative analysis. The research instrument used a learning outcomes questionnaire, geometry learning outcomes test, and documentation. The results showed that the development of augmented reality as a learning medium can be used to have a positive influence on the effectiveness of lessons in the classroom. But on the other hand, the weakness of augmented reality media is that students must use a minimum Android-based smartphone device and have a camera in it. The study results obtained are to produce AR learning media that can improve mathematical spatial abilities.

Multiplication of fractions is one of the operations on fractions that tends to be easy, but it becomes a problem for students. Only a little previous research has examined the multiplication of fractions and the factors that cause this problem at the tertiary level. This study aims to describe the factors that cause problems in terms of the types of learning barriers that students experience. The research design is hermeneutics phenomenology. The participants in this study were 15 students aged 18-25 years, 7 boys and 8 girls, 9 students majoring in natural sciences during high school, and 6 students from social studies majors. The researcher is the main instrument, with a fraction multiplication test consisting of 2 questions developed by NCTM and a semi-structured interview guide as an additional instrument. Data is processed using NVivo-12-assisted thematic analysis to simplify the coding process. The study revealed that students experienced more learning difficulties when working on non-routine fraction multiplication problems. For routine problems, students experience learning difficulties with the type of ontogenic obstacle that is psychological (not careful). For non-routine problems, students experience learning barriers with epistemological types because they rarely work on word problems, as well as ontogenic obstacles that are conceptual and psychological.
